衛(wèi)生級(jí)單座氣動(dòng)換向截止閥應(yīng)用:該換向座閥是一種衛(wèi)生級(jí)單座氣動(dòng)操作閥門，在食品加工工業(yè)，飲料生產(chǎn)制藥和精細(xì)化工工業(yè)中有著廣泛的應(yīng)用。操作原理該座閥由單作用或雙作用的氣動(dòng)執(zhí)行器自動(dòng)操作。壓縮空氣推動(dòng)軸來定位閥門開或關(guān)的位置。換向閥是具有兩種以上流動(dòng)形式和兩個(gè)以上油口的方向控制閥。是實(shí)現(xiàn)液壓油流的溝通、切斷和換向，以及壓力卸載和順序動(dòng)作控制的閥門。可分為手動(dòng)換向閥、電磁換向閥、電液換向閥等。 又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時(shí)改變流體流向。工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸，帶動(dòng)搖拐臂，啟動(dòng)閥板，使工作流體時(shí)而從左入口通向閥的下部出口，時(shí)而從右入口變換通向下部出口，實(shí)現(xiàn)了周期變換流向的目的。這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過閥瓣來變換工作流體的流向。
衛(wèi)生級(jí)單座氣動(dòng)換向截止閥閥板式的優(yōu)點(diǎn)
動(dòng)作準(zhǔn)確、自動(dòng)化程度高、工作穩(wěn)定可靠，但需附設(shè)驅(qū)動(dòng)和冷卻系統(tǒng)，結(jié)構(gòu)較為復(fù)雜；閥瓣式結(jié)構(gòu)則較簡單，多用于流量較小的生產(chǎn)工藝上。在石油、化工、礦山和冶金等行業(yè)中,六通換向閥是一種重要的流體換向設(shè)備。該閥安裝在稀油潤滑系統(tǒng)輸送潤滑油的管道中。通過變換密封組件在閥體中的相對(duì)位置,使閥體各通道連通或斷開,從而控制流體的換向和啟停。

T-type sanitary stop valve
Applications The divert seat, valve is a kind of hygienicsingle-seat valve pneumatically ,which is applied to a wide range ofapplication in the food-processing industry, beverage production.pharmaceutical and fine chemicals industries.
Operating principle Seatvalves are operated automatically by a single-acting or a
double-actingpneumatic actuator. By supplying compressed air，the shaft is moved to place the valve in the "open" or”closed”position.
The180°rotation of the pneumatic cylinder of single-actingactuators allows to have a normally open or normally closed valve.
Design and features Compact androbust design. 3A certified valve.
Availablesizes: from DN 25/1" to DN 100/4".
Normally closed valve (NC) in the standard version.
Thevalve can be changed to normally open (NO) by simply reversing the position ofthe pneumatic actuator. Hygienicdesign according to 3A standards. 360°adjustable body. Openlantern allows visual inspection of shaft sealing. Easy assembly/disassembly of internal parts byloosening a clamp fastener.
Standardweld connections (mm or inches).
