BURKERT塑料閥體球閥,BURKERT塑料膜片閥,德國BURKERT球閥
BURKERT塑料閥體球閥屬于強制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進入閥門時，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會發(fā)生閥桿頂彎的故障。近年來，從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進入閥腔，這時在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時，在介質(zhì)作用下，這種形式的閥門也較嚴密。我國閥門“三化給”曾規(guī)定，截止閥的流向，律采用自上而下。本閥要水平安裝截止閥開啟時，閥瓣的開啟高度，為公稱直徑的25%～30%時，流量已達到zui大，表示閥門已達全開位置。
