style="text-indent:25px">電站閘閥有兩種標(biāo)準(zhǔn)形式,一種是遵循ANSIB16.34和JISL1E101標(biāo)準(zhǔn)的引進(jìn)型,另一種是按JB3595標(biāo)準(zhǔn)的國(guó)標(biāo)型.其遵循的溫度-壓力等級(jí)是一致的,在一些管道中存在著某種互換關(guān)系。中部采用無(wú)閥蓋壓力自緊式,在高溫高壓工況下具有良好的密封性能。自密封圈有兩種材料,一種是低碳鋼,另一種是柔性石墨316絲（網(wǎng)）。密封面上層焊鉆基硬質(zhì)合金,其加工后的純金屬層≥3mm,具有耐磨,耐高溫,抗腐蝕,抗擦傷,使用壽命長(zhǎng)。支管兩端為焊接結(jié)構(gòu),焊按坡口可按標(biāo)準(zhǔn)或用戶要求制作。適用于火電廠,石油化工,冶金等高溫高壓的水,冶金等高溫高壓的水,蒸汽,油品,過(guò)熱蒸汽的管道上。</p><p style="text-indent:25px">閘板是閘閥中的重要部件，因此，為了使閘閥的作用得到有效發(fā)揮，就要高度重視它的密封性，并在制作或者維修等環(huán)節(jié)重視關(guān)鍵部件。在閘板運(yùn)用的過(guò)程中，所受到的力主要來(lái)源于拉伸力與壓縮力，另外，還有流體所帶來(lái)的沖刷和沖擊。對(duì)于密封面來(lái)說(shuō)，擠壓力以及摩擦力是其所受的壓力。而閘板的壓力是殘余應(yīng)力和靜壓力，其中殘余應(yīng)力是受制造因素的影響，靜壓力受閥座及液體的影響。由受力分析可知，多樣性和復(fù)雜性是閘板所具有的特性，在受到外界重負(fù)荷時(shí)，閘板就會(huì)出現(xiàn)損傷。同時(shí)，在眾所作用力的影響下，液體得到強(qiáng)化，進(jìn)而腐蝕了閘板的密封體，降低了閘板的密封性，從而導(dǎo)致閘板出現(xiàn)損傷。電站閘閥維修方便，閘閥結(jié)構(gòu)簡(jiǎn)單，密封圈一般都是活動(dòng)的，拆卸更換都比較方便。</p><div
