一、概述Outline

QJ(A/B/C)R型氣動(dòng)活塞兩段切斷球閥是一種能實(shí)現(xiàn)兩次開(kāi)或兩次關(guān)動(dòng)作的切斷球閥，是一種較為先進(jìn)的氣動(dòng)執(zhí)行器。它是由球閥、活塞執(zhí)行機(jī)構(gòu)、電磁閥、單向閥、快速排氣閥等部件組成，由于執(zhí)行機(jī)構(gòu)采用了快速排氣及節(jié)能功能，使兩段球閥具有非常優(yōu)良的開(kāi)關(guān)特性，使開(kāi)閥、關(guān)閥速度減緩，使管道中流體變化平穩(wěn)，不會(huì)因沖擊產(chǎn)生水錘現(xiàn)象使易燃流體發(fā)生爆炸，亦不會(huì)因沖擊而損壞系統(tǒng)中流量計(jì)及其它儀表，因而適用于石油、化工、輕工、國(guó)防等行業(yè)的流量定量控制系統(tǒng)，特別適用于油品貯運(yùn)系統(tǒng)。

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.
