梭式止回阀在管道输送中的应用

Application of shuttle check valvs in pipeline

介绍了梭式止回阀及系列产品 (专利产品 ) 〔1〕:梭式消防止回阀、梭式通球止回阀在管道输送中的应用。它的技术特性优于一般止回阀 ,在结构上采用缓闭形式 ,减缓了水锤压力的增高。消防止回阀泄漏量为零。通球止回阀能利用流体自身的动力全自动转换通球。

This paper mainly intrduces shuttle check valves,a series of derived products,and their applications in pipeline.The shuffle check valve is a kind of patent products 〔1〕 .The derived products include shuttle Fire-Fighting check valves,shuttle check valve with ball cleaner passing through,etc.,the mentioned products have better technical advantages comparing with the tradifional check valves which is of the characteristics of buffering water hammer effect by structure of slow-closing.For shuttle Fire-Fighting check valve,the leakage is zero.For shuttle check valve with ball cleaner passing through,the valve is able to alternate its two position,check valve position or passing-ball position,automatically with internal energy of the fluid.
