襯氟止回閥是一種依靠介質(zhì)本身的流動(dòng)而自動(dòng)啟閉閥瓣用來阻止介質(zhì)逆向流動(dòng)的自動(dòng)防腐閥門，又稱逆止閥或單向閥。中文名H41F46型襯氟止回閥型號(hào)H41F46型類別襯氟止回閥通徑DN25～DN350目錄1止回閥類型2工作原理3法蘭標(biāo)準(zhǔn)4規(guī)格范圍5注意事項(xiàng)H41F46型襯氟止回閥止回閥類型編輯一）H41型：水平安裝、升降式止回原理二）H40型：垂直安裝、浮球式止回原理三）H42型：垂直安裝、升降式止回原理四）H44型：垂直安裝、旋啟式止回原理H41F46型襯氟止回閥工作原理編輯1旋啟式止回：它的閥瓣都是圍繞閥座外的軸旋轉(zhuǎn)啟、閉，防止介質(zhì)倒流。軸與閥瓣設(shè)計(jì)為一體，全部襯氟的軸鑲嵌在閥體與閥蓋之間形成的特殊凹槽內(nèi)，啟閉靈活，密封可靠。2.浮球式止回：是一種新型結(jié)構(gòu)，閥瓣為球型，特點(diǎn)是襯氟浮球沿閥體通路軸線做升降運(yùn)動(dòng)，液體只能讓垂直向上流動(dòng)，一旦液體停直向上流動(dòng)時(shí)，浮球靠本身的重量自動(dòng)掉落至原位，與閥體內(nèi)部的密封圈相結(jié)合，致使閥門自動(dòng)關(guān)閉。3.升降式止回：結(jié)構(gòu)特點(diǎn)是襯氟閥瓣垂直于閥體進(jìn)、出口軸線作升降運(yùn)動(dòng)，其優(yōu)點(diǎn)是止回的密封性能非常好。H41F46型襯氟止回閥法蘭標(biāo)準(zhǔn)編輯法蘭遵循國(guó)家標(biāo)準(zhǔn)、、，可供用戶自由選擇（具體尺寸用戶可查詢相關(guān)數(shù)據(jù)表或來電咨詢我公司）。</p><p> 止回閥這種類型的閥門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；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型的閥門，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的狀況***體壓力幾乎不受阻礙，因此通過閥門的壓力降相對(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，流體通過升降式止回閥的通道也是狹窄的。江蘇鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。</p><div
