通过本文的阅读,读者将对顶部导向型单座调节阀有一个全面的认识,并能够深入了解其在工程实践中的重要性和价值。

2. 顶部导向型单座调节阀原理:2.1 原理概述顶部导向型单座调节阀是一种常见的工业控制阀,其主要原理是通过改变阀内流体通道的截面积来实现对流体流量的调节。

该阀门采用单个座封闭管道,并将阀芯安装在管道上方,因此被称为顶部导向型。

2.2 结构说明顶部导向型单座调节阀由以下几个基本组件构成:底盘、阀盖、阀芯、密封装置和驱动装置。

底盘提供了支撑和稳定性,同时通过进出口连接管道。

阀盖是固定在底盘上覆盖整个阀体的部分,它包含了操作系统和密封环。

阀芯作为开启或关闭流体通道的关键组件,通过移动来改变流经管道的截面积。

密封装置则负责保持阀门关闭状态时的密封性能,并减少泄漏风险。

驱动装置可以是手动操作、电动或气动执行器等不同形式,用于控制阀芯位置。

2.3 工作原理解释当顶部导向型单座调节阀处于关闭状态时,阀芯与底盘紧密接触,并由密封装置提供密封性能。

当需要调节流体流量时,驱动装置会使阀芯上移,缩小管道截面积,增加阻力和压降。

source.It is used primarily in a building with several risers,with tempered water in each riser controlled by a separate master mixer.NOTE:The engineer must determine maximum distance which can be run,i.e.maximum allowable time for hot water to reach user with one shower head operating,based upon code requirements and/or good practice.METHOD #2METHOD #2setup INSTRUCTIONSBefore any attempt is made to adjust this system,be sure the temperature of the hot water at the source is properly set and maintained.1.Be sure system is piped in accordance with Method #2.2.Shut off circulator.3.Open

电动调节阀的结构与工作原理

电动调节阀的结构与工作原理

电动调节阀的结构与工作原理一、电动调节阀的结构1、电动调节阀的基本结构电动调节阀上部是执行机构,接受调节器输出的0~10mADC或4~20mADC信号,并将其转换成相应的直线位移,推动下部的调节阀动作,直接调节流体的流量。

各类电动调节阀的执行机构基本相同,但调节阀(调节机构)的结构因使用条件的不同类型很多,的是直通单阀座和直通双阀座两种。

2、电动执行机构的基本结构其电动执行器主要是由相互隔离的电气部分和传动部分组成,电机作为连接两个隔离部分的中间部件。

电机按控制要求输出转矩,通过多级正齿轮传递到梯形丝杆上,梯形丝杆通过螺纹变换转矩为推力。

因此梯形螺杆通过自锁的输出轴将直线行程传递到阀杆。

执行机构输出轴带有一个防止传动的止转环,输出轴的径向锁定装置也可以做动位置指示器。

输出轴止动环上连有一个旗杆,旗杆随输出轴同步运行,通过与旗杆连接的齿条板将输出轴位移转换成电信号,提供给智能控制板作为比较信号和阀位反馈输出。

同时执行机构的行程也可由齿条板上的两个主限位开关开限制,并由两机械限位保护。

3、执行机构工作原理电动执行机构是以电动机为驱动源、以直流电流为控制及反馈信号。

当控制器的输入端有一个信号输入时,此信号与位置信号进行比较,当两个信号的偏差值大于规定的死区时,控制器产生功率输出,驱动伺服电动机转动使减速器的输出轴朝减小这一偏差的方向转动,直到偏差小于死区为止。

此时输出轴就稳定在与输入信号相对应的位置上。

4、控制器结构控制器由主控电路板、传感器、带LED操作按键、分相电容、接线端子等组成。

智能伺服放大器以专用单片微处理器为基础,通过输入回路把模拟信号、阀位电阻信号转换成数字信号,微处理器根据采样结果通过人工智能控制软件后,显示结果及输出控制信号。

在过程控制系统中,执行器接受调节器的指令信号,经执行机构将其转换成相应的角位移或直线位移,去操纵调节机构,改变被控对象进、出的能量或物料,以实现过程的自动控制。

T967H、T967Y型PN200、PN250钢制调节阀显缓解,东北、西北基本平衡。

按照发改委的预测,在连续40多个月发电量增速超过两位数后,今年我国电力供需矛盾可基本缓解,而明年除少数地区高峰时段外,全国大部分地区可实现电力供需平衡,并略有盈余。

另有分析认为,目前我国的用电结构仍以工业为主,工业用电占全社会用电总量的比重超过七成。

在电价上调和控制高耗能产业措施实施后,高耗能产业盲目发展势头受到遏制,高耗能产业集中地区的用电负荷增速趋缓,将对缓解用电紧张起到重要作用。

套筒导向单座调节阀工作原理

套筒导向单座调节阀工作原理

套筒导向单座调节阀工作原理套筒导向单座调节阀,这个名字听起来是不是有点像高大上的机械设备?乍一听,可能让你想到了复杂的工业大机器,或者某个神秘的技术术语,像是只有工程师才能懂的专用词汇。

但其实呢,它就是一个在管道里安静地“做着贡献”的小东西,虽然不显眼,却非常重要!咱们来聊聊它到底是怎么工作的,顺便也了解一下它背后的那些有趣的原理。

你得明白,这个调节阀长得差不多就像一个普通的阀门,但它的内涵可不一般。

大家都知道阀门嘛,就是用来控制流体流动的东西。

有的阀门是用来打开的,有的是用来关闭的,但这个“单座调节阀”可不简单,它的任务是根据实际需要,随时调节流体的流量、压力,甚至温度。

而“套筒导向”这几个字,意思就是里面有个特殊的导向结构,能够帮助阀芯在阀座里平稳移动。

可以说,它是为了“避免失控”的一种设计——像开车时,车轮得有个轮轴,才能确保行驶稳定对吧?套筒导向就起到了类似的作用。

那它到底是怎么工作的呢?别着急,听我慢慢给你讲。

流体会从管道进入调节阀,阀体上有一个阀芯。

这个阀芯其实就像个“调皮”的小家伙,随着不同的控制信号,它会往上移或者往下移,就像你按下电梯按钮,电梯会根据楼层来上下走动一样。

调节阀的“控制信号”来源可不是你按的按钮,而是阀门上方的执行器。

执行器就像一个“大脑”,根据你给它的“指令”调整阀芯的位置,从而实现对流体流量的控制。

你可能会想,这个阀芯可真灵活啊,能上下跑来跑去。

不过,阀芯也得在阀座里走得稳才行。

如果它跑偏了,可能会造成泄漏或者不稳定的流量控制,这就是套筒导向的作用啦!它给阀芯提供了一个稳定的“轨道”,让它在移动时不容易发生偏移。

可以想象一下,如果没有这个套筒导向,阀芯就像没有指引的小船,可能在管道里东撞西碰,怎么控制流量啊?所以说,套筒导向是确保阀芯稳定运行的“保驾护航”角色。

说到这里,或许你开始明白为什么“单座调节阀”那么重要了。

它不仅能精确控制流量,还能保证流体在管道中的运行稳定。

(9)ApplicationThe V5004T Kombi-QM is a Pressure Independent Control Valve (PICV). It combines a flow controller and a full stroke, full authority temperature controller in one valve.Equipped with an actuator Kombi-QM provides a full stroke modulating temperature control.It is suitable for use in variable and constant flow systems. They may be used as constant flow limiter in constant flow systems (without an actuator) or as a Pressure Independent Control Valve in variable flow systems.V5004T Kombi-QM is typically used for balancing and tempera-ture control of fan coil units, air handling units, chilled ceilings and one-pipe heating systems.Special Features•Automatic pressure independent balancing and control -Precise pressure independent flow performance-Highest energy saving potential due to efficient energy transfer and minimized pump speed-Integrated measuring possibility to find the optimal setpoint for the pump-Reduced movements of actuators as pressure fluctuations do not influence the required temperature -No complex calculation needed for selection -No balancing method needed for commissioning •Wide range of application -Sizes DN15 up to DN150-Various versions to support standard flow rates as well as low flow and high flow needs-Covers two functions in one valve which reduces mounting costs•Easy commissioning-Pre-setting with visual flow scale at the valve -Pre-setting by hand without the need of tools-Pre-setting possible even when the system is running and an actuator is already mounted-Can balance a system even if only parts of a building are in operation•Maintenance friendly-Emergency shutoff function with plastic cap – not for per-manent use-Measuring possibility for problematic applicationsValve EfficiencylowhighEnergy efficiency Commissioning Effort Calculation effortV5004T Kombi-QM2 E N 0 H -2 3 2 7 G E 2 3 R 0 3 1 6•S u b j e c t t o c h a n g eTechnical Data ConstructionThe V5004TY Kombi-QM (DN15 - DN25) consists of:•Valve housing with internal threads to DIN EN10226-1 for threaded pipe and two G1/4" equipped with SafeCon TMpressure test valves•Hand wheel with scale for pre-setting the valve•Valve insert with diaphragm assembly•Plastic cover cap to protect actuator connection.

The dynamic balancing function maintains a constant differential pressure over the control valve. The control valve regulates the flow by means of a variable orifice which is controlled by the actuator. The constant differential pressure across the control valve ensures accurate control and full valve authority, independent of the pres-sure conditions in the system.Valve Identification Each valve is marked as follows:•OS-Number•DN size•PN rating•Flow arrows•Serial number/date codeNominal size DN15 – DN25DN20 – DN32DN32 – DN65DN50 – DN150Housing Dezincification-resis-tant brass Dezincification-resis-tant brassDuctile iron Ductile ironMedium Water or water-glycol mixture, quality to VDI 2035(up to 50% Glycol)pH-value8...9.5Operating temperature-10...120°C (25...248°F)k vs (c vs)-value see table on page 6Operating pressure (PN)max. 25bar (363psi)max. 16bar (232psi) Differential pressure range∆p min see table on page 6∆p max400kPa (4bar)Flow values see table on page 6Leakage According to Class IV IEC 60534-2-3V5004T Kombi-QM 3E N 0H -2327G E 23 R 0316 • S u b j e c t t o c h a n g eOverviewV5004TY Kombi-QM (DN15 - DN25)V5004TY Kombi-QM (DN20-DN32)V5004TY Kombi-QM (DN32-DN65)V5004TF Kombi-QM (DN50-DN150)123456Constant pressure regulatorInterface for connection of Honeywell linear actuators Flow pre-setting knob with scale from 0% to 100%Pre-setting without tools possibleSafeCon TM pressure test valve with color marked protection capGrey protection cap - can be used as emergency shutoff knobLockable pre-setting5614OutletInlet32123456Constant pressure regulatorInterface for connection of Honeywell linear actuators Flow pre-setting knob with scale from 0% to 100%Pre-setting without tools possibleSafeCon TM pressure test valve with color marked protection capGrey protection cap - can be used as emergency shutoff knobLockable pre-setting5314OutletInlet6212345Constant pressure regulatorInterface for connection with rotating Honeywell actuators Additional manual shut-off device Regulating partSafeCon TM pressure test valve with color marked protection cap2314OutletInlet51234Constant pressure regulator Regulating actuator Regulating partSafeCon TM pressure test valve with color marked protection cap213OutletInletV5004T Kombi-QM4E N 0H -2327G E 23 R 0316 • S u b j e c t t o c h a n g eDimensionsV5004TY Kombi-QM (DN15-DN25)V5004TY Kombi-QM (DN20-DN32)V5004TY Kombi-QM (DN32-DN65)V5004TF Kombi-QM (DN50-DN150)NOTE:All dimensions in mm unless stated otherwise.DN Thread ABCD E 15Rp 1/2"9911720Rp 3/4"32982510812425Rp 1"130132D ECADN Thread ABCD E 20Rc 3/4"1761725Rc 1"321383818421.532Rc 1 1/4"20922ADEEDN Thread A B C D E 32*Rc 1 1/4"2328517615823.640Rc 1 1/2"2318517615823.650*Rc 2"2788517615823.650Rc 2"267932211982865**G 2 1/2"2059322119819* Valve with DN40 valve body** External threaded valve with DN50 valve bodyEAEDDN Flange size H1H2L D K d C 502"191291254165125181865 2 1/2"1853002721851451818803" 18530027220016018201004"26032035222018018201255"26634640025021018221506"3504004002852402222CLK D N dDH 1H 2V5004T Kombi-QM 5E N 0H -2327G E 23 R 0316 • S u b j e c t t o c h a n g eOrdering InformationAvailable versions and OS-Nos (OS=Ordering Specification)NOTE:* Valve is fully open / without actuatorFlanged valves V5004TF**** DN50 to DN150, come together with an actuator as one unit.
