您好!歡迎訪問浙江阿斯塔閥門科技有限公司網(wǎng)站!
一、概述Outline
QJ(D/S)RG型精小型氣動高壓O型球閥是一種轉(zhuǎn)角為90°的球閥。閥體采用三開(三體)式法蘭連接球閥,球芯采用固定式結(jié)構(gòu),需要操作力矩小,聚四氟乙烯閥座采用浮動嵌入式結(jié)構(gòu),密封性能優(yōu)良。執(zhí)執(zhí)行機構(gòu)采用ZGH、ZGQ高性能氣缸活塞執(zhí)行機構(gòu),結(jié)構(gòu)簡單,輸出力矩大。該球閥適宜控制含有纖維和固定顆粒的高壓或高壓差流體。雙作用氣動高壓O型球閥型號為QJSRG-160/320,單作用氣動高壓O型球閥型號為QJDRG-160/320。
QJ (D / S) RG-type O-intensive small pneumatic high pressure valve is a valve angle of 90 °. Open three-body (three-body) type flanged ball valve, ball core fixed structure, need to operate a small torque, the embedded PTFE floating seat structure, good sealing performance. Executive actuator using ZGH, ZGQ high performance cylinder piston actuators, simple structure, the output torque. Gai control valve suitable for particles with high fiber and fixed or fluid pressure differential. O-type double-acting pneumatic high pressure valve model QJSRG-160/320, single-acting pneumatic high-pressure O-type ball valve Model QJDRG-160/320.
