Q671F對(duì)夾式氣動(dòng)球閥是氣動(dòng)球閥中的一種超薄型的氣動(dòng)球閥,是新一代超短法蘭距球閥,球芯通道形狀有矩形、V形及O形。氣動(dòng)球閥具有結(jié)構(gòu)緊湊、體積小、重量輕、安裝方便等特點(diǎn)。閥門可廣泛應(yīng)用在石油、化工、冶金、電站、輕工等領(lǐng)域,對(duì)油、水、氣及紙漿或纖維狀流體進(jìn)行自動(dòng)調(diào)節(jié)或切斷控制。它采用直連方式執(zhí)行機(jī)構(gòu)連接,具有結(jié)構(gòu)緊湊、尺寸小、重量輕、摩擦阻力小、回差小、動(dòng)作穩(wěn)定可靠等優(yōu)點(diǎn).氣動(dòng)球閥由氣動(dòng)雙活塞齒輪齒條執(zhí)行器和超短法蘭距球閥組合而成,閥體部分同“1”電氣動(dòng)球閥閥體一樣。氣動(dòng)活塞執(zhí)行機(jī)構(gòu)分有彈簧式和無彈簧式兩種。故障下要求閥全開或關(guān)閉時(shí)配有彈簧式(靠彈簧的恢復(fù)張力復(fù)位),故障下要求保位時(shí),配無彈簧式。它主要由缸體、彈簧、活塞、活塞桿、前后缸蓋、齒條、輸出軸等零部件組成。對(duì)兩位開關(guān)閥,需配電磁閥以及行程開關(guān)等;對(duì)比例式調(diào)
