進(jìn)口電動(dòng)高真空球閥,(德國OLES奧萊斯閥門)
【進(jìn)口電動(dòng)高真空球閥】詳細(xì)說明：
電動(dòng)高真空球閥是應(yīng)用在真空系統(tǒng)中,又能適用一定的壓力下開啟或切斷氣流的高真空球閥。執(zhí)行機(jī)構(gòu)采用回轉(zhuǎn)型電動(dòng)，電子調(diào)節(jié)式驅(qū)動(dòng)裝置，通過外接電源切換或外部輸入信號(hào)來實(shí)現(xiàn)閥門啟閉或中間位置的控制。電動(dòng)高真空球閥外形結(jié)構(gòu)緊湊，美觀，密封座補(bǔ)償式設(shè)計(jì)。球閥有自動(dòng)補(bǔ)償密封座磨損功能，密封可靠，壽命長等優(yōu)點(diǎn)。適用的工作介質(zhì)為帶酸、堿性的各類氣體或液體
Electric high vacuum ball valve is a kind of high vacuum ball valve which is used in vacuum system and can open or cut off airflow under certain pressure. The actuator adopts rotary electric and electronic adjustable driving device to control the opening and closing of the valve or the middle position of the valve by switching the external power supply or inputting the external signal. Electric high vacuum ball valve has compact shape, beautiful appearance and compensatory design of sealing seat. The ball valve has the advantages of automatic compensation for wear of sealing seat, reliable sealing and long service life. The suitable working medium is various gases or liquids with acid and alkalinity.
產(chǎn)品特性：
●電動(dòng)高真空球閥密封結(jié)構(gòu)設(shè)計(jì)*，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；
●開關(guān)扭矩小，配置氣動(dòng)執(zhí)行器小，工作穩(wěn)定、可靠；
●高真空球閥結(jié)構(gòu)緊湊，重量輕，外形簡潔、美觀；
●該球閥既能適用高真空，又能適用一定的正壓力下使用；
●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)。
產(chǎn)品工作原理：
浮動(dòng)球閥采用特殊設(shè)計(jì)的雙斜面彈性密封圈，有效的降低了球體與密封圈之間的摩擦力，減少了操作力矩。當(dāng)介質(zhì)壓力較小時(shí)，密封圈與球體接角面積較小，故有較大的密封比壓，確?？煽棵芊狻．?dāng)介質(zhì)力較大時(shí)，密封圈與球體面積也相應(yīng)增大。故密封圈能承受較大的介質(zhì)推力而不會(huì)損壞，確保可靠密封。當(dāng)介質(zhì)的沖刷力較大時(shí)，特別設(shè)計(jì)的閥座防沖刷結(jié)構(gòu)能有效的防止介質(zhì)的沖刷，確保密封圈的使用壽命。對(duì)于低壓，超低壓或真空工況用球閥，因介質(zhì)本身的壓力不能確保閥座可靠密封，而預(yù)緊力*使用后又會(huì)衰減，特別設(shè)計(jì)的彈簧加載密封結(jié)構(gòu)，能確保閥門*可靠使用。
