Static sound type Check Valves Mainly by the valve chest, the valve seat, the conduction current body, the valve petal, the bearing and the spring and so on the major parts is composed, the internal flow channel uses the streamline form design, the pressure loss is minimum. The valve petal opens shuts the traveling schedule to be very short, stops when the pump may close fast, prevented the giant impingement sound, has the static sound closure characteristic.
This valve mainly uses in giving draining water, the fire prevention, passing the system warmly, may install in the water pump exit, prevented flows backwards and the impingement to harm。
