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(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí)，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(huì)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(jìn)入閥腔，這時(shí)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(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)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(shí)，閥瓣的開啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到zui大，表示閥門已達(dá)全開位置。
