國(guó)標(biāo)截止閥
產(chǎn)品概述
J41H/Y型國(guó)標(biāo)截止閥屬于強(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)入閥六時(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。國(guó)標(biāo)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,表示閥門已達(dá)全開位置。所以截止閥的全開位置,應(yīng)由閥瓣的行程來決定。
國(guó)標(biāo)截止閥具有以下優(yōu)點(diǎn):
1、結(jié)構(gòu)簡(jiǎn)單,制造和維修比較方便。
2、工作行程小,啟閉時(shí)間短。
3、密封性好,密封面間磨擦力小,壽命較長(zhǎng)。
