style="font-size:16px;">止回閥在水泵圈內(nèi)，大家都不陌生。按照結(jié)構(gòu)分類分類，可以分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種：1.升降式止回閥分為臥式和立式兩種2.旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。3.蝶式止回閥為直通式以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接、焊接連接和對(duì)夾連接四種。這次我們主要是來了解一下對(duì)夾連接的止回閥，我們又稱之為對(duì)夾止回閥，也屬于升降式止回閥、單向閥。止回閥用于管路系統(tǒng)，作用是為了防止介質(zhì)倒流、防止泵及其啟動(dòng)電機(jī)反轉(zhuǎn)，以及容器內(nèi)介質(zhì)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(bǔ)給的管路上。止回閥安裝在管路上，即成為這一完整的流體部件之一，其閥瓣啟閉過程就要受它所處系統(tǒng)瞬變流動(dòng)狀態(tài)所影響；反之，閥瓣的關(guān)閉特</span><span
