氣動(dòng)真空(壓力)球閥是適用于真空系統(tǒng)中接通或切斷管路中的介質(zhì)流。該閥以壓縮空氣為動(dòng)力,通過(guò)控制氣動(dòng)元件來(lái)改變氣路方向,推動(dòng)活塞齒條、齒輪的機(jī)械運(yùn)動(dòng),以角行程輸出扭矩來(lái)驅(qū)動(dòng)球閥作啟閉運(yùn)動(dòng)。閥門(mén)為直通式,靠球面密封,因而既能用在真空狀態(tài)下,也能在低壓狀態(tài)下使用,并可任意位置安裝。氣缸分為雙作用和單作用(彈簧復(fù)位),可選配反饋信號(hào)裝置及電氣閥門(mén)定位器。Pneumaticvacuum (pressure) ball valve is suitable for connecting or cutting off themedium flow in pipelines in vacuum systems. The valve is powered by compressedair and changes the direction of the air circuit by controlling the pneumaticcomponents, driving the mechanical movement of the piston rack and gear, andoutputting torque through angular stroke to drive the ball valve for openingand closing motion. The valve is a straight through type, sealed by a sphericalsurface, which can be used in both vacuum and low-pressure conditions, and canbe installed in any position. The cylinder is divided into double acting andsingle acting (spring return), and can be optionally equipped with feedbacksignal devices and electrical valves
進(jìn)口氣動(dòng)高真空球閥產(chǎn)品特點(diǎn)
1、密封結(jié)構(gòu)設(shè)計(jì)獨(dú)特,漏率可達(dá)到<1×10-10Pa.M3/S,改變了球閥不能滿足高真空、超高真空的現(xiàn)狀;
2、開(kāi)關(guān)扭矩小,配置氣動(dòng)執(zhí)行器小,工作穩(wěn)定、可靠;
3、結(jié)構(gòu)緊湊,重量輕,外形簡(jiǎn)潔、美觀;
4、該閥既能適用高真空,又能適用一定的正壓力下使用;
5、由于球閥全通導(dǎo),又能達(dá)到超高真空要求,所以也能適用于加速器真空系統(tǒng)。
