Y-type fast-closing check

Y-type fast-closing check valve closure characteristics of Y-type is mainly used for fast pump outlet when the pump stops, the fast check to prevent water hammer effect produced. When pump, valve at the bottom thrust rise, open the valve, but quickly closed the spring force of the spring, when the water flow is close to zero, the valve is fully closed. Anhydrous back phenomenon, but because the water can not turn the clock back, no kinetic energy, it prevents water hammer production. Y-type quick closing check valve Product Introduction Y-type fast-closing check has become fast-closing check when triple, which includes a valve seat, stem, spring, valve and other ancillary parts, pump clapper rises in water thrust to open the valve. At the same time the action of pressure spring is quickly closed, when the flow approaches zero, the valve is fully closed. No backflow water, no power, to prevent water hammer production. Features: 1 to prevent water hammer generation, 2, shut no noise. 3, small head loss. 4, the scope is broad. 5, good sealing effect. Suitable for water, sewage and drainage systems. Y-type quick closing check main valve Y-shaped membrane structure, with the seal pair of non-metallic seals, valves generally require horizontal mounting, in the form of pipe connection flange connection, flange dimensions to perform according to International Standard: GB /T17241.6.
