style="text-indent:25px">電站止回閥的清理檢查：檢查閥芯及閥體上的閥線，閥線上應無影響密封性能的凹槽、氣孔及橫貫密封面的痕跡，應全周接觸無間斷。若發(fā)現(xiàn)有影響密封性能的缺陷應進行研磨等處理。檢查閥蝶與搖臂間的連接情況，調(diào)整墊片與搖臂間隙為1～1.2mm之間，不應過大也不應過小，否則應進行調(diào)整。閥蝶與搖臂的緊固螺母連接應牢固，定位的焊點應完整、無裂紋，閥蝶軸與搖臂圈的間隙應符合要求。之后檢查杠桿軸、搖臂軸與大小襯套及播臂的間隙應符合要求，各軸表面及襯套內(nèi)壁表面應光潔、無凹坑。</p><p style="text-indent:25px">止回閥選型標準：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(zhì)流向要由下而上；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(zhì)不同可以適用任何工作介質(zhì)和任何工作溫度范圍。介質(zhì)為水、蒸汽、氣體、腐蝕性介質(zhì)、油品、藥品、等。介質(zhì)工作溫度范圍在-196--800℃之間；旋啟式止回閥適用場合是低壓大口徑，而且安裝場合受到限制。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(zhì)倒流。</p><div

style="text-indent:25px">止回閥是指啟閉件為圓形閥瓣并靠自身重量及介質(zhì)壓力產(chǎn)生動作來阻斷介質(zhì)倒流的一種閥門。屬自動閥類，又稱逆止閥、單向閥、回流閥或隔離閥。閥瓣運動方式分為升降式和旋啟式。升降式止回閥與截止閥結(jié)構(gòu)類似，*缺少帶動閥瓣的閥桿。介質(zhì)從進口端(下側(cè)）流入，從出口端（上側(cè)）流出。當進口壓力大于閥瓣重量及其流動阻力之和時，閥門被開啟。反之，介質(zhì)倒流時閥門則關(guān)閉。旋啟式止回閥有一個斜置并能繞軸旋轉(zhuǎn)的閥瓣，工作原理與升降式止回閥相似。止回閥常用作抽水裝置的底閥，可以阻止水的回流。止回閥與截止閥組合使用，可起到安全隔離的作用。電站止回閥應安裝在水平管道上介質(zhì)流向從下往上流(正流)。徐州自密封止回閥價格</p><p

1.產(chǎn)品設(shè)計制造按E101和JB/T3595-93標準的規(guī)定，結(jié)構(gòu)合理，性能優(yōu)良，造型。 2.閥門中腔采用壓力自緊式密封結(jié)構(gòu)，介質(zhì)壓力越高,密封性能越好。 3.支管兩端為對焊連接，適應不同的接管要求。 4.閥瓣、閥座的密封面采用鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷性能好、使用壽命長。 5.高溫耐壓部件采用質(zhì)量耐熱合金鋼制造,安全可靠,性能穩(wěn)定,使用壽命長。徐州自密封止回閥價格</p><p
