H41Y-25I、H41Y-40I、H41Y-64I、H41Y-100I鉻鉬鋼高溫高壓升降式止回閥
H41Y-100C(P)不銹鋼高壓止回閥
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，介質回流導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構，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。

止回閥(cheek valve)：止回閥又稱單向閥或逆止閥，其作用是管路中的介質倒流。水泵吸水關的底閥也屬于止回閥類。啟閉件靠介質流動和力量自行開啟或關閉，以介質倒流的閥門叫止回閥。止回閥屬于自動閥類，主要用于介質單向流動的管道上，只允許介質向一個方向流動，以發(fā)生事故。止回閥按結構劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種。升降式止回閥可分為立式和臥式兩種。旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。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、法蘭連接和焊接三種。
