3、產(chǎn)品按國家標準GB/T12235設計制造。閥門承壓件采用精密鑄造工藝澆鑄，表面質量美觀，無粘沙、冷隔等表面破損;內在質量穩(wěn)定，無疏松、砂眼、裂紋等內在破損。 4、可采用各種配管法蘭標準及法蘭密封型式，滿足各種工程需要及用戶要求。 5，浙江日標升降止回閥生產(chǎn)廠家、閥體材料品種齊全，墊片可根據(jù)實際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質工況。可按用戶要求設計制造不同結構形式和連接形式的止回閥，為各種設備配套使用，浙江日標升降止回閥生產(chǎn)廠家。 6,用于管路系統(tǒng)，浙江日標升降止回閥生產(chǎn)廠家，其主要作用是防止介質倒流、防止泵及其驅動電機機反轉，以及容器內介質的泄放。止回閥還可用于給其中的壓力可能升至超過主系統(tǒng)壓力的輔助系統(tǒng)提供補給的管路上。電站止回閥應安裝在水平管道上介質流向從下往上流(正流)。浙江日標升降止回閥生產(chǎn)廠家</p><div

style="text-indent:25px">H41H升降式止回閥的設計：1、升降式止回閥的閥瓣呈圓盤狀，繞閥座通道的轉軸作旋轉運動，因閥內通道成流線形，流動阻力比升蝶式止回閥小，適用于低流速和流動不常變化的大口徑場合，但不宜用于脈動流，其密封性能不及升降式。蝶式止回閥分單瓣式、雙瓣式和多半式三種，這三種形式主要按閥門口徑來分，目的是為了防止介質停止流動或倒流時，減弱水力沖擊。2、升降式止回閥：閥瓣沿著閥體垂直中心線滑動的止回閥，內螺紋止回閥只能安裝在水平管道上，在高壓小口徑止回閥上閥瓣可采用圓球。蝶式止回閥的閥體形狀與截止閥一樣（可與截止閥通用），因此它的流體阻力系數(shù)較大。其結構與截止閥相似，閥體和閥瓣與截止閥相同。浙江自密封升降止回閥生產(chǎn)廠家電站止回閥的閥瓣在流體壓力作用下開啟，流體從進口側流向出口側。</p><div

①產(chǎn)品的設計制造符合美國國家標準ANSIB16.34，美國石油協(xié)會標準APl6D要求。 ②美標止回閥的閥瓣為旋啟式，流道為直通式，水平管道、垂直管道均可安裝。 ③美標止回閥的搖桿銷軸采用內裝式結構，減少了外泄漏缺點。 ④閥體，閥蓋為螺栓連接，高壓情況下(PN≥10MPa)。中法蘭采用內壓自密封結構，使得美標止回閥體積小，重量輕，密封可靠。</p><p style="text-indent:25px">一、H41H升降式止回閥概述：升降式止回閥選用于公稱壓力PN1.6～6.4MPa,工作溫度-29～550℃的石油、化工、火力電站等各種工況的管路上。適用介質為：水、油品、蒸汽等。二、H41H升降式止回閥結構特點： 1、升降式止回閥具有結構簡單，動作可靠，維修方便等優(yōu)點，普遍應用于凈化設備、石油、化工、冶金、電力、輕紡等生產(chǎn)過程中 2、當介質由閥體箭頭所示流向進入閥體，介質的壓力作用在閥瓣上產(chǎn)生向上的推力，當介質推力大于閥瓣重力時，閥門打開。當閥后介質壓力作用在閥瓣上的力加上閥瓣自身重力大于閥前壓力作用在閥瓣上的力時，閥門關閉，阻止介質倒流。可按用戶要求設計制造不同結構形式和連接形式的止回閥，為各種設備配套使用。H41H升降式止回閥適用介質為水、油品、蒸汽、酸性介質等。</p><div

4、止回閥應安裝在水平管道上介質流向從下往上流（正流）。在管線中不要使電站止回閥承受重量，大型的止回閥應**支撐，使之不受管系產(chǎn)生的壓力的影響。成都高壓升降止回閥廠家</p><p style="text-indent:25px">電站止回閥:止回閥又稱單向閥或逆止閥，其作用是防止管路中的介質倒流。也屬于止回閥類。浙江日標升降止回閥生產(chǎn)廠家</p><p style="text-indent:25px">止回閥的選型標準內容如下：球形止回閥1、為了防止介質逆流，在設備、裝置和管道上都應安裝止回閥；2、止回閥一般適用于清凈介質，不宜用于含有固體顆粒和粘度較大的介質；3、一般在公稱通徑50mm的水平管道上都應選用臥式升降止回閥；4、直通式升降止回閥只能在水平管道安裝；5、對于水泵進口管路，宜選用底閥，底閥一般只安裝在泵進口的垂直管道上，并且介質自下而上流動；6、升降式較旋啟式密封性好，流體阻力大，臥式宜裝在水平管道上，立式裝在垂直管道上；7、旋啟式止回閥的安裝位置不受限制，它可裝在水平、垂直或傾斜的管線上，如裝在垂直管道上，介質流向要由下而上；8、旋啟式止回閥不宜制成小口徑閥門、可以做成很高的工作壓力，公稱壓力可達到42MPa，而且公稱通徑也可以做到很大，比較大可以達到2000mm以上。根據(jù)殼體及密封件的材質不同可以適用任何工作介質和任何工作溫度范圍。介質為水、蒸汽、氣體、腐蝕性介質、油品、藥品、等。介質工作溫度范圍在-196--800℃之間。浙江日標升降止回閥生產(chǎn)廠家</p><p
