【詳細說明】

一、概述Outline

QJ(A/B/C)R型氣動活塞兩段切斷球閥是一種能實現兩次開或兩次關動作的切斷球閥,是一種較為先進的氣動執行器。它是由球閥、活塞執行機構、電磁閥、單向閥、快速排氣閥等部件組成,由於執行機構采用了快速排氣及節能功能,使兩段球閥具有非常優良的開關特性,使開閥、關閥速度減緩,使管道中流體變化平穩,不會因衝擊產生水錘現象使易燃流體發生爆炸,亦不會因衝擊而損壞係統中流量計及其它儀表,因而適用於石油、化工、輕工、國防等行業的流量定量控製係統,特彆適用於油品貯運係統。

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.
