进口高加系统阀详细说明,特点/用途,报价【进口高加系统阀】特点：入口阀和止回阀配套使用,往高压加热器注水后，随着水的压力不断升高，当压力升至一定的压力后，借助作用于入口阀阀杆截面的压差使阀杆向上运动带起阀瓣开通了进入高压加热器的通道，使水进入高压加热器，此时高压加热器投入运行。当高压加热器发生事故管系***，高压加热器内水位超过允许值时，水位信号通过电器装置打开快速启闭阀，凝结水进入入口阀上部活塞缸内，压下活塞,推动阀瓣下移，关闭高压加热器的进口，打开旁路，高压加热器停止运行，整个动作时间为2秒钟。Theinletvalveandcheckvalveareusedtogether.Afterwaterisinjectedintothehighpressureheater,thepressureofwaterincreasescontinuously.Whenthepressurerisestoacertainpressure,thevalvestemmovesupwardwiththehelpofthepressuredifferenceactingonthecrosssectionoftheinletvalvestem,andthevalvediscopensthepassageintothehighpressureheater,sothatthewaterentersthehighpressureheater.Atthistime,thehighpressureisadded.Theheaterisputintooperation.Whenthehigh-pressureheaterpipesystembreaksdownandthewaterlevelinthehigh-pressureheaterexceedstheallowablevalue,thewaterlevelsignalopensthequickopeningandclosingvalvethroughtheelectricaldevice,condensatewaterentersthepistoncylinderoftheupperpartoftheinletvalve,depressesthepiston,pushesthevalvediscdown,closestheinletofthehigh-pressureheater,opensthebypass,andthehigh-pressureheaterstopsrunning.Thewholeactiontimeis2seconds.产品技术参数：主体材质：;1、WCB、ZG20CrMo、Cr5Mo、ZG20CrMoV2、25#、12Cr1MoV3、ASTMA216WCB、ASTMA217WC6、ASTMA217WC94、ASTMA105、ASTMA182F11、ASTMA182F22使用温度：1、WCB：-29℃~425℃2、合金钢：-29℃-540℃、-29℃-570℃适用介质：水、蒸汽等连接方式：焊接传动方式：手动、电动、液动)
