style="text-indent:25px">蝶式止回閥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、全方面的與閥座接觸。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下，其流體壓力幾乎不受阻礙，因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣座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。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，因此通過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。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。美標(biāo)電站止回閥的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。</p><div
