進(jìn)口快速排污閥
德國(guó)巴赫進(jìn)口快速排污閥概述：
進(jìn)口快速排污閥是由閘閥演變而來(lái)的，利用齒輪轉(zhuǎn)90℃帶動(dòng)閥桿提升實(shí)現(xiàn)開(kāi)啟和關(guān)閉的目的。
進(jìn)口快速排污閥不僅結(jié)構(gòu)簡(jiǎn)單、密封性好，而且體積小，重量輕、材料耗用少、安裝尺寸小，特別是驅(qū)動(dòng)力矩小，操作簡(jiǎn)便，易實(shí)現(xiàn)快速啟閉。
Quick inlet valve
Overview of the German Bach imported fast blowdown valve:
Rapid import valve is evolved from the gate valve, the use of gear to turn 90 degrees to promote the stem to achieve the purpose of opening and closing.
Import quick drain valve has the advantages of simple structure, good sealing performance, small volume, light weight, less consumption of materials, installation of small size, especially the driving torque is small, simple operation, easy to achieve rapid opening and closing. Quick inlet valve

進(jìn)口快速排污閥的定義：
進(jìn)口快速排污閥是直接依靠介質(zhì)壓力產(chǎn)生的作用力來(lái)幫助作用于閥瓣上的機(jī)械荷密封的，作用 在閥瓣上的機(jī)械載荷主要是來(lái)自壓縮彈簧，這種幾乎是固定的機(jī)械載荷。雖然對(duì)于壓縮彈簧，加載的排污閥可以通過(guò)調(diào)整彈簧力來(lái)達(dá)到良好密封，但密封壓差必須足夠強(qiáng)，以保證足夠的密封力，從而在閥正常運(yùn)行時(shí)達(dá)到密封。密封壓差還應(yīng)小于啟閉壓差，以確保開(kāi)啟靈活。
Import quick drain valve definition:
Import quick drain valve force is directly dependent on the media to help generate pressure acting on the valve flap on the mechanical seal bearing, mechanical load on the valve flap is mainly from the compression spring, which is almost constant mechanical load. Although the compression spring, valve loading spring force can be adjusted to achieve a good seal, the sealing pressure must be strong enough to ensure adequate sealing force, thereby sealing the valve during normal operation. The sealing pressure difference should be less than the opening and closing pressure difference to ensure the flexibility of opening.
