各种燃气阀门的介绍 -

各种燃气阀门的介绍建设部十分重视对燃气阀门的规范性建设,燃气阀门的行业标准有CJ3005-1992《城镇燃气用灰铸铁阀门的通用技术要求》、CJ3055-1995《城镇燃气用阀门的试验与检验》、CJ3056--1995《城镇燃气用球墨铸铁和铸钢制阀门的通用技术条件》、2002年6月又通过了《家用手动燃气阀门》的行业标准。

这些标准的制订和颁布规范了阀门行业、推动了燃气阀门的进步和发展、促进了燃气事业的发展;为研制、生产、使用单位提供了参考依据;提高了对燃气阀门与通用阀门区别的认识,保证了燃气阀门的安全裕度;受到了燃气同行们的欢迎一、RX系列油密封式旋塞阀上世纪八十年代,我国燃气主要是人工煤制气,蝶阀人工煤制气中有较多的杂质和"煤气胶",原来传统使用的单闸板契式水闸阀越来越不能适应燃气工况的需要,这类阀门普遍存在"关不严"和阀杆咬死的问题,我们参考日本技术研制而成的RX系列燃气用油密封式旋塞阀,解决了关不严和阀杆咬死的问题二、RZ系列燃气用平行双闸板闸阀随着燃气事业的发展和煤气厂的纷纷建立,需要较大甚至特大公称通径的燃气专用阀门,RZ系列燃气用平行双闸板闸阀针对人工煤气形成的问题给予一一解决,最大通径达1600mm1、平行双闸板闸阀在启闭过程中能刮去密封面上的"煤气胶",解决了煤气杂质黏附在密封面上影响阀门密封的大问题2、装有阀杆保护套,使阀杆不受"煤气胶"的侵蚀3、阀门下部带有排污孔侧盖,可以清扫落在阀腔底部的垃圾4、全通径设计流阻小,又能通清管器5、阀体采用特殊设计的"鼠笼框架式加强筋"减轻了阀门总体重量,增强了壳体强度和刚度6、RZ系列燃气闸阀壳体选用灰铸铁制造,价格低廉;第七、该系列闸阀带有全封闭的启闭指示器,使操作者清楚了解阀门所处状态三、RQZ系列球墨铸铁制燃气用平行双闸板闸阀随着我国天然气进入城镇,笔者与上海煤气总公司、苏州市燃气设备阀门制造有限公司根据天然气的特点又研制了RQZ球墨铸铁制燃气用平行双闸板闸阀,该闸阀除保留了RZ系列闸阀的特点外,选用的材质增强了阀门的耐磨性,同时将压力等级提高到了高压B级四、蝶阀蝶阀相比上述几种阀门轻便,口径大,价格较低,八十年代初期部分煤气公司曾-度采用蝶阀,经过十年左右的使用,普遍认为效果不好。

全气动注油机及其油脂泵设计说明书

全气动注油机及其油脂泵设计说明书

2011届本科生毕业设计(论文)课题名称250全气动高压注油机及其油脂泵的设计专业机械设计制造及其自动化专业方向机电一体化班级07102112A1学号0710211217学生姓名陈业飞指导教师杨征瑞教研室机械电子上海应用技术学院机械与自动化工程学院250全气动高压注油机及其油脂泵的设计摘要:注油机主要运用于隧道、矿山、冶金,起重运输类的轴承及其他摩擦部位的润滑油加注。

目前大多数注油机的主要特点是手动或电动控制,效率均不高,且手动注油机劳动强度大,使用有局限性,出油压力不高。

国内对全气动高压注油机的研究较少,大多需要国外进口,价格昂贵。

本毕业设计的题目是气动注油机及控制系统的设计。

是为满足上海隧道工程的需要,为隧道工程机械润滑而设计的注油机。

设计正文气动注油机部分为总体方案选择、油脂泵的设计及控制实现方案、驱动气缸的设计三大部分注油机的设计在前期已经基本研究成功,已经投入生产。

但是,原来的注油机使用的是电控制,在隧道这种比较潮湿的环境中容易发生机器的故障及工作人员的人身安全问题。

所以,在原来的设计上加以改进,运用气动传动的优点,提高机器的适应性和可靠性。

气动注油机因以空气作为动力源,较易取得,用后的空气可直接排入大气中,处理方便,与液压相比不必设置回收油的油箱与管道,污染少,较能体现现在的环保概念。

有因空气的黏度很少,其损失也很小,所以便于集中供气,实远距离传送,这对于像隧道工程这样的地下操作是很方便的。

气压传动的环境适应性好,特别在易燃、易爆、多尘埃、强磁、辐射、振动严重的恶劣工作环境中,比如这次的隧道工程。

而且考虑到这次课题的设计要求,注油机的排量是:往复一次连续排油180ml,行程为120mm,注油压力为42 MPa,其注油量较高。

由于干油黏度很高,不易吸压,所以其工作频率不能很高,故综合考虑这些因素,本次设计的总体方案采用气动控制。

关键词:全气动注油机,高压,连续且流、排量可调The pneumatic high-pressure note oil 250mm design of themachineGeneral Information Design:Oiling machine is mainly used in tunnel, mining, metallurgy, materials handling classes and other friction bearing parts of the oil filling.Most current note oil machine main characteristic is a manual or electric control, efficiency are not high, and the manual labor intensity note oil machine, using has limitations, the oil pressure is not high. To the pneumatic high-pressure injection domestic oil feeder research less, mostly need foreign imports, the price is high.The graduation project is the subject of air oiling machine and control system design. Shanghai Tunnel Engineering is to meet the needs of lubrication for the tunnel project designed oiling machine.Design text pneumatic note oil machine parts for overall plan selection, grease pump design and control implementation scheme, driving cylinder design three sections.Pneumatic note oil machine for air as power supply, easily obtained, with the air after can be directly into the atmosphere, compared with convenient, handling of hydraulic oil tank not setting recovery less contamination with pipe, can reflect now, with the environmental protection concept. The viscosity for air, the loss is rarely facilitates concentration was small, so the supply, real long distance transmission, this for like tunnel project such an underground operation is very convenient. Pneumatic transmission good adaptability to the environment, especially in inflammable, explosive, dusty, strong magnetic, radiation, vibration serious odiously working environment, such as the tunnel project. And considering the topic design requirements, note oil machine emissions is: a continuous 180ml, reciprocating 120mm trip for the soot, note the oil pressure for 42 MPa, its note oil amount is higher. Because oil viscosity is very high, do not easy absorption of pressure, so its working frequency, it can high considering these factors, the design scheme of adopt pneumatic control.Keywords: all the pneumatic note oil machine, high pressure, flow, displacement is adjustable目录1 绪论 (1)1.1 研究目的及其意义 (1)1.2 注油机的分类 (1)1.3 发展趋势 (2)1.4 注油机的介绍 (2)1.4.1 手动液压注油机 (2)1.4.2 电动黄油注油机 (3)1.4.3 液压润滑脂注油机 (5)1.4.4 矿车轮注油机 (6)1.4.5 气动干油泵注油机 (9)1.5 总体分析 (13)2 油脂泵的设计 (15)2.1 总体方案的确定 (15)2.2 活塞杆的设计计算 (17)2.3 油脂泵缸筒壁厚的设计 (20)2.4 活塞的设计计算 (21)2.5 缸盖的连接螺栓的设计 (22)2.6 密封的设计 (23)2.7 增压盘的设计 (24)2.8 定压安全阀的设计 (25)3 气动控制系统的设计 (25)3.1 方案的比较及分析 (25)3.2 控制系统的方案确定 (27)4 驱动气缸的设计 (28)4.1 缸筒壁厚的设计 (28)4.2 活塞杆的设计 (29)4.2.1 活塞杆的初步选择 (30)4.2.2 活塞杆计算 (30)4.2.3 活塞杆强度校核 (30)4.3 耗气量的计算 (31)4.4 气缸进排气口直径的计算 (32)4.5 缸筒与缸盖的连接设计 (33)4.6 密封的设计 (33)5 升降气缸的设计 (36)5.1 缸筒内径的设计 (36)5.2 缸筒壁厚的设计 (38)5.3 活塞杆的设计 (39)5.3.1 初选活塞杆规格 (40)5.3.2 计算L/D (40)5.3.3 稳定性校核 (40)5.3.4 计算细长杆比 (40)5.3.5 确定系数m (41)5.3.6 校核活塞杆 (42)5.4 耗气量的计算 (42)5.5 气缸进排气口直径的计算 (43)5.6 密封的设计 (44)6 注油机总体设计 (48)7 设计小结 (50)8 特别致谢 (51)9 参考资料 (52)1 绪论1.1 研究目的及其意义注油机目前主要用于重型,矿山机械行业。

2、系统配置及原理
根据我国国家标准《输气管道工程设计规范》GB50251以及欧美 国家标准如《燃气输配系统中的调压站—功能要求》EN12186的 要求,燃气调压站、计量站中压力控制系统中的调压阀应优先选 用自力式调压阀,在流通能力方面宜采用流通能力较好的轴流式 调压阀。自力式调压器结构简单、维护方便,以广泛用于国内外 的压力控制系统。
调节原理:当出口用气量增加或入口压力降低时,燃气出口压力下降,造成皮膜上下压 力不平衡,此时皮膜下降,阀口开大,燃气流量增加,使压力恢复平衡状态。反之,当 出口用气量减少或入口压力增大,燃气出口压力升高,此时皮膜上升,使阀门关小,燃 气量减少,又逐渐使出口压力恢复至原来状态。

For category C5-M, an epoxy resin coating is recommended.Application, Characteristics, Technical DataDesign and function of the gas pressure regulator (GPR)The gas pressure regulators RSP 254/255 have the function of keeping the outlet pressure of a gas train downstream of a gas pressure regulator largely constant within specified limits, independently of changes in the gas tap or inlet pressure. The required auxiliary energy is obtained from the pressure gradient between the inlet pressure and outlet pressure of the gas pressure regulator. No external energy is required, and no gas whatsoever will flow out of the system into the surrounding atmosphere in standard operation. The regulator consists of the regulating unit, optionally connected upstream to a micro filter and bypass valve.The control variable - the outlet pressure - is detected by a sensitive diaphragm in the regulating unit, which is part of a double-diaphragm system. The pneumatic amplifier working by the nozzle/baffle plate principle is actuated by the comparator formed by a double-diaphragm system. The bypass valve and possible changes in the setpoint spring can be used to affect the static amplification of the regulator and adjust it to the respective condition of a gas train.The outlet pressure is applied to the top side of the double-diaphragm system in the regulating unit via a measurement line, converted into a pressure force and compared with the set setpoint spring force as command variable. Any deviation from the control value is followed by a suitable proportional change in the spacing between nozzle and baffle plate, corresponding to a proportional change in the setting pressure. The valve opening required in each case for adjusting the outlet pressure actual value to the setpoint is effected by the setting pressure generated by the actuating drive of the actuator.In the operating state, the inlet pressure taken at the inlet flows as auxiliary energy through the nozzle/baffle plate system and the bypass valve into the outlet pressure chamber, generating, depending on the position of the nozzle/baffle plate system, the setting pressure for the valve opening position required in each case against the bypass valve. The auxiliary energy gas then flows back to the outlet pressure network via the bypass valve.In case of zero tap of the gas train, the amplifier valve in the double-diaphragm system of the regulating unit will close tight, causing the closing pressure to be established.Models with pneumatic follow-up setpoint inputs with 1:1 and 1:2 pressure conversions are available. Using, for example, IP converters allows you to continuously set directly the required outlet pressure setpoint via, for example, 4 to 20 mA signals.Moreover, by means of a setting spring, variable zero points can be suppressed.Design and function of the safety shut-off valve (SSV) direct-actingIn case of inadmissible overpressure or lack of gas in the gas train, the actuator of the safety shut-off valve arranged in the same housing on the inlet side will shut off the gas flow.To this end, the outlet pressure to be monitored is passed on to the SSV control device via a separate measurement line. As a function of the change in pressure, the SSV diaphragm in the control device is raised or lowered. When the outlet pressure in the gas train exceeds or falls below a certain response pressure, the switch socket connected to the SSV diaphragm will move to the corresponding disengaging position, the balls of the engaging mechanism will release the SSV screw spindle, and the closing spring will press the SSV valve plate against the valve seat. The SSV actuator shuts off the gas flow gas-tight. The SSV can only be opened by hand and engaged in the open position. To do so, the outlet pressure at the measuring point must be lowered below the upper response pressure or raised above the lower response pressure by at least the re-engaging differential amount (Δp). The SSV can, except where otherwise stipulated in national legislation, be used either in function class A (with diaphragm rupture protection) or B (without diaphragm rupture protection).There is also the option of using a remote display for the SSV position 'CLOSED' and a manual and remote release when power is applied or in case of power failure.Design and function of the safety shut-off valve (SSV) indirect-actingAt a safeguarding pressure of the gas train of greater than 4 bar, the SSV must be combined with a control device K70-10. In this case, the SSV switching device is designed as function class B and set to a switching pressure of approx. 500 mbar. The control device K70-10 connected upstream of the switching device is set to the upper safeguarding pressure. As soon as the pressure of the gas train reaches the upper safeguarding pressure, the control device will open and allow the gas pressure to flow to the measurement connection of the SSV switching device. Here a pressure of more than 500 mbar will build up, causing the switching device to release as described above. The excess pressure in the measurement line will be let down by flowing into the breather line via the bypass throttle and safely released into the atmosphere.Setting deviceSSVActuator housingSSV connection optionsBV breather valve Sectional viewActuator AS 255• Wdsoup to4 bar with controldevice MD or MD-R• Wdsofrom 4 bar with controldevice K 70-10 (indirect-acting)Option: Noise reductioncontrol deviceInlet pressureSetting pressureOutlet pressureAtmosphereNoise reductionFF micro filter for R70FF micro filterSectional viewRegulators R 70-10, R 70-20, R 70-100 and SSV control device K 70-10R 70-10R 70-20R 70-100Double-diaphragm systemDouble-diaphragm systemSetpoint spring 100 cm 2Measuring movementSetpoint springBypass setting deviceR 70-20with pneumatic 1:2 pressure converter for follow-up setpoint adjustment, for example, via I/P converterBypass setting device 20 cm 2Measuring movementDouble-diaphragm systemSetpoint spring Double-diaphragm system10 cm 2Measuring movementI/P converter Pressure converter20 cm²K 70-10SSV control deviceSetpoint setting deviceSetpoint setting deviceSetpoint setting deviceBypass setting deviceApplication, Characteristics, Technical DataK G * valueAccuracy class AC / Closing pressure group SG*) KG value for natural gas: d = 0.64 (ρn = 0.83 kg/m³), t ugas = 15 °C **)Optionally, the control device K70-10 can be used as SBV.(Δp u,max ± 2bar )Setting device is approved for a max. pressure differential of 0.5 barUpper response pressure group AG30 mbar to 100 mbar AG 10100 mbar to 500 mbar AG 5> 500mbar AG 2.5Lower response pressure AG5 mbar to 30 mbar AG 2030 mbar to 50 mbar AG 10> 50mbar AG 5Response pressure group AG (SSV direct-acting)Upper response pressure group AG800 mbar to 4,000 mbar AG 2.5> 4,000 mbar AG 2,5Response pressure group AG(SSV indirect-acting) control device K 70-10**Determining the upper response pressureOutput pressure P dUpper response pressure W dso *≤200 mbarP d +100 mbar >200 mbar to ≤800 mbar P d x 1.5>800 mbar to ≤1600 mbarP d x 1.3> 1600mbarP d +500 mbarP h Pneumatic follow-up setpoint from I/P converter (0-6 bar)P d100 Outlet pressure R70-100 P d20 Outlet pressure R70-20 P d 20s Outlet pressure R70-10 with follow-up setpoint 1:2P d10 Outlet pressure R70-10 P d 10s Outlet pressure R70-10 with follow-up setpoint 1:1P dOutlet pressure K70-10*) The upper response pressure is rounded up to full tens, for example 251 mbar-> 260 mbarRegulator setpoint spring tableDimensions, Connection and WeightAS 254: Connection of the functional line and breather lineNominal widthSetting deviceSSV control device direct-actingSetting pressure line / Return lineSSV measurement lineBreather lineDN 025Connection* for: Tube 12 x 1.5 (thread G 3/8)Connection* for: tube 12 x 1.5 (thread G 1/4)DN 050DN 080DN 100DN 150Connection* for: tube 12 x 1.5 (thread G 3/8)DN 200AS 255: Connection of the functional line and breather linesNominal widthSetting deviceSSV control device direct-actingSetting pressure line / Return lineSSV measurement lineBreather lineDN 050Connection* for: Tube 12 x 1.5 (thread G 3/8)Connection* for: tube 12 x 1.5 (thread G 1/4)DN 080DN 100Connection* for: tube 12 x 1.5 (thread G 3/8)*) Threaded pipe connections to DIN EN ISO 8434-1 (DIN 2353)Note: Observe the following documents in relation to installation, start-up and maintenance:DVGW - work sheets G 491 and G 600Operating and Maintenance Instructions RSP 254 / 255The gas pressure regulators RSP 254 / 255 shall be installed in the pipeline preferably in horizontal position.

这种阀还配备有两个气体流量调节器,一个用于 1 段火,另一个用于2段火。

设置初始快速放气量:为设置初始快速放气量,拧紧保护盖“ F ”用于“ F ”的上部作为工具转动 螺栓“G ”。

顺时针转,减小所体流量;反时针转,增大气流量。

完成后,将“F ” 拧回原位。

设置1段火气体流速:在给1段和2段火设置气体流速成之前,拧松螺丝“ D ”(突起的圆柱型头部 未着色)。

调节完后要重新拧紧。

注意:为打开第一火焰的位置,转动第二火焰控制环“L ”, 沿反时针方向,至少转一整圈。

为设置第一火焰气体流速,转动旋钮“ E ”,顺 时针转,减小流量;反时针转,增大流量。

控制旋钮“ E ”从“+”调至“-”大 约要转三圈半,反过来也一样。

第二位置阀门完全打开,控制旋钮“ E ”完全打 开,则可获得约占总量40%的流量。

对天然气管网地区调压器配备的优化简析

对天然气管网地区调压器配备的优化简析

对天然气管网地区调压器配备的优化简析王海华【摘要】以市南地区调压器总装机容量远远大于实际需求量为问题的切入点,分析了目前中低压管网的地区调压器配备,阐述了可优化的目标,并给出了实施建议.【期刊名称】《上海煤气》【年(卷),期】2017(000)001【总页数】3页(P5-7)【关键词】燃气管网;地区调压器;优化【作者】王海华【作者单位】上海大众燃气有限公司【正文语种】中文为满足经济投入的合理性和运行的安全性,燃气通过管网系统从气源点输送至终端用户,通常采用多级的压力输送级制,调压器则是连接不同压力级制燃气管网系统的重要设施,因此,管网系统中的地区调压器的配置(主要包括调压能力、数量和位置)合理与否将直接影响到管网系统建设和维护的投入、管网供应的安全性以及用户用气体验的舒适程度,尤其是在完成管道燃气全天然气化后,如何使得管网系统中地区调压器的配备日趋合理,并使其与天然气管网运行系统更加的匹配,将是一项长期的工作,本文将着重对市南中低压地区调压器的合理配置做简要的分析与建议。

目前市南地区拥有中低压地区和街坊调压器数量合计870台,最大供应能力约为100万m3/hr,具体数据如表1所示。

然而,2015年初底冬高峰期间,市南地区燃气所有用户晚高峰最大小时流量仅28万m3/h,根据地区和街坊调压器与专用调压器总装机容量占比推算,其中通过地区和街坊调压器高峰期间流入低压管网的最大小时流量占总量的60%。

参照表1数据,也意味着地区调压器高峰期间最大小时流量约占总量的36%,即:高峰期间,地区调压器实际合计最大小时流量约为10万m3/h,仅占其最大供应能力的16.7%,也就是说,地区调压器的供应能力远远大于实际需求量。

虽然总体上供大于求,但局部地区低压管网仍存在供应不良的情况。

自 2010年开始,公司恢复了高峰期间低压管网的压力监测工作,通过连续几年低压管网的压力测试,发现局部地区低压管网仍存在供应压力过低的情况,个别楼前立管压力还不足1 500 Pa,已严重影响到低压用户的正常用气。

RS Regulator
Construction and function of the RS Regulator
RS 250 and RS 251 are gas pressure regulators with built-in savety shutoff valve. Nominal diameters 25, 50, 80, 100, 150, 200. The gas flows through the regulator housing in arrow direction (cutview). The main diaphragm is actuated via an impulse line from the outlet side by pressure. The required outlet pressure is adjusted at the spring. The single seat valve is directly mounted and operates independant from the inlet pressure by the compensation diaphragm. The savety shutoff valve (SSV) which is built into the same housing interrupts the gas flow at excess pressure or gas shortage. The diaphragm of the savety shutoff valve is actuated via an impulse line from the outlet side. When excess pressure or gas shortage lifts or drops the measure work the latch lever reacts and the closing spring presses the valve disc against t bar Pa = Pd 22-1.200mbar Q max. 1.100 Nm³/h (2.000) Nm³/h KG-Values V 27,5 459 Nm³/h V 32,5 642 Nm³/h V 42,5 1.097 Nm³/h Gas characteristics: suitable for gas of the gas families 1, 2, 3 and other neutral gaseous media.
