品牌：RETZ瑞茨/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……氣動角座閥是指利用執(zhí)行器活塞來提供線性作用力推動閥芯離開閥座的一種氣控閥門。角座閥尤其適用于高溫且流量要求較大的流體環(huán)境下，如蒸汽或者水。角座閥中某些型號，如果反向安裝，運行時會克服水錘作用 retz Pneumatic angleseat valve refers to a type of pneumatic valve that uses the actuator piston toprovide linear force to push the valve core away from the valve seat. Cornerseat valves are particularly suitable for fluid environments with hightemperatures and high flow requirements, such as steam or water. Some models ofangle seat valve will overcome Water hammer during operation if installed inreverse direction

進(jìn)口氣動法蘭角座閥產(chǎn)品詳情product details

可以在任何方向安裝∶橫向，縱向，傾斜。

雙動型和單動型產(chǎn)品能提供的口徑規(guī)格從3 /8 英寸到4英寸，可從阻塞錘上下兩端關(guān)閉，而單動型閥門從阻塞錘下端開啟

進(jìn)口氣動法蘭角座閥工作原理 working principle

1.單作用：由一個二位三通電磁閥控制。導(dǎo)向介質(zhì)壓力進(jìn)入執(zhí)行器，作用于活塞，使閥芯穿梭于閥腔中實現(xiàn)打開或關(guān)閉閥門。閥芯復(fù)位通常是借助于氣動執(zhí)行器中的彈回彈簧來完成。Single acting:controlled by a two position three-way solenoid valve. The pressure of guidingmedium enters the actuator and acts on the piston to make the valve coreshuttle in the valve chamber to open or close the valve. The valve elementreset is usually completed by means of the spring in the pneumatic actuator.

雙向常閉（N.C.）Twoway normally closed (N.C.)介質(zhì)從閥芯下方流入，可避免水錘作用。介質(zhì)在閥芯上方流入，將受到水錘擠壓;The medium flowsunder the valve core to avoid the action of water hammer. If the medium flowsabove the valve core, it will be squeezed by water hammer;

常閉型（N.C.）介質(zhì)從閥芯上方流入，介質(zhì)從閥芯上方流入會造成"水錘"效應(yīng)Normallyclosed (N.C.) medium flows from above the valve core, which will cause"water hammer" effect

常開型（N.O.）介質(zhì)從閥芯下方流入Normallyopen (N.O.) medium flows from below the valve core

2.雙作用：配置的閥門中，沒有彈回彈簧，導(dǎo)向介質(zhì)既用來打開閥門，也用來關(guān)閉閥門。

Doubleacting: there is no spring in the configured valve, and the guiding medium isused to open and close the valve.
