豐興高壓截止閥材質(zhì),TOYOOKI高壓截止閥結(jié)構(gòu)圖
它的結(jié)構(gòu) 長(zhǎng)度大于閘閥，同時(shí)流體阻力大，長(zhǎng)期運(yùn)行時(shí)，密封可靠性 不強(qiáng)。
手輪、手柄操作的截止閥可安裝在管道的任何位置上。
Cut-off valve, also known as cut-off, is the most widely used a valve, it is popular,
Is due to open and close the sealing process between the sealing surface is small, more durable,
Open height is not large, easy to manufacture, easy maintenance, not only for low pressure,
手輪、手柄及偉動(dòng)機(jī)構(gòu)，不允許作起吊用。
When the high-pressure shut-off valve is opened,
the opening height of the valve flap is 25% to 30% of the nominal diameter,
The flow has reached the maximum, indicating that
the valve has reached full position.
介質(zhì)的流向應(yīng)與閥體所示箭頭方向一致。
力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門(mén)的力比開(kāi)閥門(mén)的力大，
所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。
So the fully closed position of the cut-off valve should be determined by the stroke of the valve.
High-pressure cut-off valve is mandatory sealing valve, so when the valve is closed,
Pressure must be applied to the flap to force the sealing surface from leakage.
近年來(lái)，從自密封的閥門(mén)出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔，
這時(shí)在介質(zhì)壓力作用下，關(guān)閥門(mén)的力小，而開(kāi)閥門(mén)的力大，
But also for high pressure. Its closed principle is to rely on the pressure of the valve,
So that the valve sealing surface and the valve seat sealing surface close to prevent the media circulation.
Only one-way flow of the valve, the installation of directional.
閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門(mén)也較嚴(yán)密。
