Structural installation: 1. The valve of the flange check valve is a disc and rotates around the rotating shaft of the seat channel. Because the inner channel of the valve is streamlined, the flow resistance is smaller than the butterfly check valve, which is suitable for large caliber occasions with low flow rate and variable flow, but it should not be used for pulsatile flow, and its sealing performance is not as good as the Ball Check Valve. Butterfly check valve is divided into single...

Introduction: The back pressure valve moves through the elasticity of the built-in spring: when the system pressure ratio is small, the diaphragm blocks the line under the action of the spring elasticity; when the system pressure is high, the diaphragm compression spring, the line is on, and the liquid passes through the back pressure valve. The PVC Pressure Reduce Valve structure is similar to the check valve, but the opening pressure is greater than the check valve, between 0.2 to 1.6 mpa. In...

The spiral nozzle shoots the liquid in the spiral into a spiral metal protruding into the outer hole. This breaks the traditional fluid flow into relatively fine many concentric rings would form complete cone-shaped spray patterns. The resulting is an uneven distributed spray pattern rather than a full conical spray pattern. Spiral nozzles with injection purposes are suitable for injecting fluid into a gas stream rather than into the liquid stream. The flow can be as low as 0.534 l / minute....
