Open the required gas flow channels byremoving the suitable plugs from the valvebody.2. Take care that dirt can not enter the gasvalve during handling3. Install the screw-in additional hardware asrequired (vent, by-pass, external pilotvalve)4. Please refer to the relevant instructionsheetCONSTRUCTION AND WORKINGPRINCIPLESThe VQ400M combination gas valves are 2 x class “A” fail safe shut-off valves. The valve is opened by energizing the direct ON / OFF operator. The direct ON / OFF operator consists of a coil and stopsleeve assembly. Inside the top sleeve assembly a plunger is placed which is able to move up anddown and thus opening or closing the valve. Theplunger is gliding on two anti-friction bearings. Flow regulation is done by adjustable plunger stroke. A strainer made out of steel AISI 303 is incorporated between inlet flange and main body.

苏州阀门行业简析

苏州阀门苏州阀门目前已形成产业链集中、规模优势强，龙头企业云集的闻名中外阀门产业庞大的重要品牌基地。

随之世界范围内唯一专业性的国际阀门展也看好苏州，阀门世界展会先后在苏州举办了二届的国际性专业展会，世界主要阀门技术人员和采购商云集苏州作交流，共同提高世界阀门技术，更增添了苏州阀门基地在中外的知名度。

由“中核科技”(中核苏阀)领军的苏州阀门生产行业近几年快速发展，从苏州走向世界，组成了强大的产业优势，目前全市已拥有阀门内资企业40多家，同时一批外资阀门企业的进驻也提升了苏州在这一领域的地位。

据际通宝泵阀网记者的了解，2010年阀门产销额不完全统计约35多亿元，2011年预计可达到45多亿元。

江苏阀门重点区域-苏州市，依托人杰地灵的优势，抓住地理环境等有利条件，经过近几年的快速发展，迅速崛起成为我国又一大阀门规模型制造基地，开放的苏州不仅形成了我国又一大的阀门制造基地，而且形成了以苏阀、纽威，道森、思达德、维萨等骨干为主、一批外资、内资民营企业为辅组成产业链。

苏州这几年阀门产业快速发展是与苏州经济发达息息相关，加上中核苏阀是阀门业技术与制造精英，市场经济的滚滚浪潮，催动着一批原国企能人、技术高手、经营骨干走上社会，抓住机遇，勇闯市场，创业发展，孕育出如纽威阀门、苏州思达德阀门、道森控制、德兰能源、悦达阀门、维萨阀门等一批新的阀门企业，大部分阀门产品外销国外。

他们在苏州地方大胆创业，很快成长发展，已是阀门业“出口后起之秀”。

其中苏州道森控制公司、苏州思达德阀门公司和维萨阀门去年外销均达1。

5-5亿元左右，这些新办企业所产阀门产品大部分销往国外。

思达德阀门2011年又新征地扩建1万平方米的新厂房，扩大球阀的生产量。

苏州是我国阀门行业第一家上市公司、阀门业实力强大的--中核苏阀的所在地，经过50多年的发展，苏阀培养了一批阀门优秀专业人才，这批懂技术、又有管理组织技术能力的能人，纷纷走向市场，跃身市场经济的大潮，在苏州地区一带创办了一批阀门厂家，近10多年中先后有原苏阀分管销售的副总王保庆在新区创办了苏州纽威阀门、原负责苏阀生产的舒志高等在相城区创办了苏州道森阀门、原负责苏阀出口的陈浩民和韩剑荣在园区创办了苏州思达德阀门、原苏阀技术出身的宗新和史道兴在相城区创办了苏州德兰能源科技公司、原苏阀张国红在新区创办的苏州福润机械制造公司、还有原苏阀的朱卫负责在吴中区的苏州莱特阀门公司、原苏阀主管生产副总徐中亮负责在吴中区的苏州悦达阀门公司等股份民营企业，这些新办的企业发展势头快，已构成新生力量，成为苏州地区重要的阀门骨干企业，苏州纽威产销不仅超过中核苏阀，而且跻身我国阀门业的龙头企业行列。

Value Proposition:The IR4000 Series regulator offers high pressure capability with an inlet pressure up to 4,000 psig. Its large, convoluted Hastelloy ® C-22 diaphragm provides stable pressure control and corrosion resistance. Close tolerances and tight alignment of moving components minimize hysteresis and improve cycle life.IR4000 SeriesSingle-Stage, General Purpose Pressure RegulatorInternal Threadless • Stainless SteelProduct Features:• U nique compression member loads the seal to the body without requiring a threaded nozzle or additional seals • Internally threadless design reduces particle generation; low internal volume reduces purge times • Positive upward and downward stops increase cycle life by preventing over stroking of the diaphragm •Selection of seat materials for media compatibility and temperature applicationsINSTRUMENTATION PRODUCTS DIVISIONSpecifications:For additional information on materials of construction, functional performance and operating conditions, please contact factory.Hastelloy ® is a registered trademark of Haynes International, Inc.PEEK™ is a trademark of Victrex plc.Vespel ® is a registered trademark of DuPont Performance Elastomers L.L.C.Inconel ®is a registered trademark of Special Metals Corporation2IR4000 Series Lit.# 25000226 03/18Instrumentation Products Division2468101214O u t l e t P r e s s u r e (p s i g )N 2 Flow (slpm) IR4000 .06 C V10203040506070O u t l e t P r e s s u r e (p s i g )N 2 Flow (slpm)IR4002 .06 C V102030405060708090100110120O u t l e t P r e s s u r e (p s i g )N 2 Flow (slpm)IR4003 0.15 CWhen setting the delivery pressure,ensure that the maximum outlet pressure of the regulator is not exceeded for any operating condition including increases in delivery pressure due to flow shutoff and supply pressure effect.

冷冻专业设备型号S7A、S7AL的液压阀门说明书

It is advisable to install a strainer upstream of each valve to prevent entrance of foreign material into the valves and the rest of the system. Refrigerating Specialties strainers are available to close-couple to valve inlets.
Manual Opening Stem
The manual opening stem on the Type S7A is for the purpose of opening the valve without energizing the solenoid coil. Refer to the exploded view and parts list for location of the stem and other related parts. For access to the stem the seal cap on the bottom of the valve must be removed. This must be done with caution as refrigerant may have been trapped inside the seal cap. Manual opening is accomplished by turning the stem clockwise until only the flats on the end of the stem protrude from the packing nut. To reset for automatic operation turn the stem counterclockwise as far as it goes.

最小流量循环阀

最小流量循环阀最小流量循环阀环流对冲原理自主创新专利专家十年奉献优异性能一流苏州德兰阀门科技开发有限公司苏州德兰阀门科技开发有限公司最小流量循环阀最小流量循环阀1.概述最小流量循环阀是发电厂锅炉给水泵配套的关键设备。

给水泵把炉水由除氧器加压至20~30Mpa或以上，送往高压加热器，最后进入锅炉。

这些给水泵需通过最起码的流量，以带出泵运行所产生的热量，防止泵的过热，并避免泵叶片产生汽蚀而损坏。

当机组刚启动时和将要停机时，锅炉给水流量很小，在事故时，锅炉需水量也会减小。

为了保证泵的正常运行，在泵的出口需要安装一套再循环系统，把一部分给水由泵出口回流至除氧器内。

该阀入口压力高达20到30MPa以上，温度141~332℃之间。

出口压力为除氧器压力，在0~0.07MPa，温度在41~109℃，属于极端恶劣工况，在此工况之下，阀门会产生严重汽蚀和冲刷而发生损坏，亦会产生很大噪音和振动，是长期以来困扰全世界阀门专家的难题。

我公司资深阀门专家，史道兴高级工程师经过多年潜心研究，发明了环流对冲式最小流量循环阀，一举攻克了最小流量阀长期存在的汽蚀严重，漏流量大，噪音超标，寿命短等诸多难题，为电厂锅炉给水泵的安全运行提供了可靠保障。

2.全新的设计理念：环流对冲式原理，多级降压结构。

环流对冲式调节阀是在多孔抗汽蚀套筒阀、多级阀芯节流调节阀、迷宫叠片式调节阀的基础上发展起来的，是高压差抗汽蚀调节阀的新一代产品。

环流对冲式调节阀的关键零件—环流对冲式盘片，采用特殊的结构和工艺。

该盘片和当前流行的迷宫式盘片相比，形状相近而功能和原理却有很大区别。

迷宫式盘片是在圆片上加工数道各自独立的沟槽，沟槽路径是曲折多弯的。

通过十几次甚至几十次改变流体方向，达到增加阻力和逐步降压，可以防止在降压过程中产生空化和汽蚀。

环流对冲式盘片在圆盘上也加工有数道至十数道沟槽。

其沟槽由同心的环形槽和径向槽互相贯通。

相邻的流道间可以沟通。

流体由外环经由径向槽流入内环。
