Abstract：This paper mainly intrduces shuttle check valves,a series of derived products,and their applications in pipdine.The shuttle check valve is a kind of patent products.The derived products include shuttlde Fire-Fighting check valves, shattle 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 ch e ck valve with ball cleaner passing through,the valve is able to alternate its tw o position,check valve position or passing-ball position,automatically with internal energy of the fluid.
Key Words：Pipeline,Show-closing,Sealing,Water hammer,Leakage |
