止回閥這種類型的閥門(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。</p><p> 微阻緩閉止回閥又稱逆止閥，其作用是防止管路中的介質(zhì)倒流。啟閉件靠介質(zhì)流動(dòng)和力量自行開(kāi)啟或關(guān)閉，以防止介質(zhì)倒流的閥門(mén)叫止回閥。止回閥屬于自動(dòng)閥類，主要用于介質(zhì)單向流動(dòng)的管道上，只允許介質(zhì)向一個(gè)方向流動(dòng)，以防止發(fā)生事故。適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)。目錄1用途：2主要材質(zhì)3標(biāo)準(zhǔn)與規(guī)范4特點(diǎn)5結(jié)構(gòu)特點(diǎn)6技術(shù)參數(shù)7尺寸重量微阻緩閉止回閥用途：編輯微阻緩閉止回閥適用于公稱壓力、微阻緩閉止回閥Class150-2500；公稱通徑DN15~1200mm、NPS1/2~48；工作溫度－196~540℃的各種管路上，用于防止介質(zhì)倒流。通過(guò)選用不同的材質(zhì)，可適用于水、蒸汽、油品、硝酸、醋酸、強(qiáng)氧化性介質(zhì)及尿素等多種介質(zhì)。微阻緩閉止回閥主要材質(zhì)編輯碳鋼、低溫鋼、雙相鋼（F51/F53）、鈦合金、鋁青銅、因科鎳爾（INCONEL625）、SS304、SS304L、SS316、SS316L；鉻鉬鋼、蒙乃爾（400/500）、20#合金。金華鼎力閥門(mén)是一家專門(mén)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

球形止回閥以其密封性好、流阻極小等性能優(yōu)勢(shì)，得到了范圍廣的應(yīng)用和推廣，其結(jié)構(gòu)從優(yōu)初的“單球式”止回閥逐步完善到“獨(dú)自多流道多球式”止回閥。止回閥是流體傳輸優(yōu)常用的設(shè)備種類之一，現(xiàn)有的止回閥存在阻力大、能耗大的問(wèn)題。降低流阻系數(shù)是流體傳輸節(jié)能的重要途徑。常見(jiàn)的止回閥包括球形止回閥、對(duì)夾式止回閥等。這些止回閥的共同缺點(diǎn)是：在流體正向流動(dòng)、止回閥打開(kāi)時(shí)，止回閥的某些零部件例如閥瓣或球體等處于流道的**，存在一定的擋水面積，對(duì)流體的流動(dòng)阻力較大，使出水壓力有所降低，因此浪費(fèi)能量。球形止回閥結(jié)構(gòu)和工作原理編輯球形止回閥是一種采用多球、多流道、多錐型倒流體結(jié)構(gòu)的止回閥，主要由前后閥體、膠球、錐型體等組成。其工作原理是：膠球在球罩內(nèi)作短行程滾動(dòng)來(lái)實(shí)現(xiàn)閥門(mén)的啟閉。當(dāng)水泵開(kāi)動(dòng)時(shí)，水在壓力的作用下沖開(kāi)膠球，使膠球滾至右側(cè)，由后閥體中的錐形體固定其位置，止回閥開(kāi)啟；泵停后，由于管路系統(tǒng)中的回水壓力，迫使膠球滾至左側(cè)前閥體，達(dá)到止回閻的關(guān)閉。膠球采用空心鋼球，外附彈性很好的橡膠既保證密封，又能保證減小關(guān)閥過(guò)程中對(duì)管道系統(tǒng)的破壞。帶孔的錐型體在閥門(mén)打開(kāi)時(shí)對(duì)鋼球起固定作用和消除膠球與錐型體接觸面積的壓強(qiáng)。杭州鼎力閥門(mén)是一家專門(mén)生產(chǎn)制造銷售止回閥的公司，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。金華對(duì)夾雙瓣旋啟式止回閥</p><p
