Product Name:
Stainless steel check valve
Description:


不锈钢止回阀

型号: H41W 口径: DN15-DN300
压力: 1.6MPA-10MPA 材质:

止回阀(cheek valve):止回阀又称单向阀或逆止阀,其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。

启闭件靠介质流动和力量自行开启或关闭,以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类,主要用于介质单向流动的管道上,只允许介质向一个方向流动,以防止发生事故。

止回阀按结构划分,可分为升降式止回阀旋启式止回阀和蝶式止回阀三种。升降式止回阀可分为立式和卧式两种。旋启式止回阀分为单瓣式、双瓣式和多瓣式三种。蝶式止回阀为直通式、以上几种止回阀在连接形式上可分为螺纹连接、法兰连接和焊接三种。
