QJ(A/B/C)R型气动活塞两段切断球阀是一种能实现两次开或两次关动作的切断球阀,是一种较为良好的气动执行器。它是由球阀、活塞执行机构、电磁阀、单向阀、快速排气阀等部件组成,由于执行机构采用了快速排气及节能功能,使两段球阀具有非常优良的开关特性,使开阀、关阀速度减缓,使管道中流体变化平稳,不会因冲击产生水锤现象使易燃流体发生爆炸,亦不会因冲击而损坏系统中流量计及其它仪表,因而适用于石油、化工、轻工、国防等行业的流量定量控制系统,特别适用于油品贮运系统。
QJ (A / B / C) R-type pneumatic piston valve is a two cut to achieve the two open cut or two off the ball movement is a more advanced pneumatic actuators. It is a ball valve, piston actuator, solenoid valve, check valve, quick exhaust valves and other components, the implementing agencies with a quick exhaust and power-saving features, the two ball has a very good switching characteristics, so that open valve, close the valve slowed down, so that changes in steady pipe flow, the impact will not produce water hammer phenomenon to the explosion of flammable fluid will not damage the system due to the impact of flow meters and other instruments, making it suitable for oil, chemical industry, light industry, defense industry, quantitative flow control system, especially for oil storage and transportation systems.
