流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動(dòng)。根據(jù)使用條件，閥瓣可以是全金屬結(jié)構(gòu)，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣，流體通過(guò)升降式止回閥的通道也是狹窄的，因此通過(guò)升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少[1]。襯氟止回閥襯氟止回閥結(jié)構(gòu)分類(lèi)編輯1、襯氟止回閥的閥瓣呈圓盤(pán)狀，繞閥座通道的轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，因閥內(nèi)通道成流線型，流動(dòng)阻力比升蝶式止回閥小，適用于低流速和流動(dòng)不常變化的大口徑場(chǎng)合，但不宜用于脈動(dòng)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(mén)口徑來(lái)分，目的是為了防止介質(zhì)停止流動(dòng)或倒流時(shí)，減弱水力沖擊。2、襯氟止回閥：閥瓣沿著閥體垂直中心線滑動(dòng)的止回閥，消聲止回閥只能安裝在水平管道上優(yōu)好安裝在垂直管道上，在高壓小口徑止回閥上閥瓣可采用圓球。消聲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(jié)構(gòu)與截止閥相似，閥體和閥瓣與截止閥相同。閥瓣上部和閥蓋下部加工有導(dǎo)向套簡(jiǎn)，閥瓣導(dǎo)向簡(jiǎn)可在閥盞導(dǎo)向簡(jiǎn)內(nèi)自由升降，當(dāng)介質(zhì)順流時(shí)，閥瓣靠介質(zhì)推力開(kāi)啟。</p><p> 止回閥這種類(lèi)型的閥門(mén)的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。通常這種閥門(mén)是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開(kāi)；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。其中止回閥就屬于這種類(lèi)型的閥門(mén)，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門(mén)一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、范圍廣的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開(kāi)的狀況***體壓力幾乎不受阻礙，因此通過(guò)閥門(mén)的壓力降相對(duì)較小。升降式止回閥的閥瓣坐落位于閥體上閥座密封面上。此閥門(mén)除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣，流體壓力使閥瓣從閥座密封面上抬起，介質(zhì)回流導(dǎo)致閥瓣回落到閥座上，并切斷流動(dòng)。根據(jù)使用條件，閥瓣可以是全金屬結(jié)構(gòu)，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣，流體通過(guò)升降式止回閥的通道也是狹窄的。寧波鼎力閥門(mén)是一家專門(mén)生產(chǎn)制造銷(xiāo)售止回閥的公司，主要有通風(fēng)止回閥，對(duì)夾雙瓣旋啟式止回閥，液力止回閥。</p><div
