surge relief valve is widely used in hydraulic engineering, hydraulic engineering of destructive water hammer is very strong, so a lot of customer requirements must be in the middle of the pipe installation of water hammer protection type Industrial Valves, which is what we call water relief valve and water hammer prevention valves. Water hammer prevention valve has two kinds, one is on the water use, water hammer is in fact the relief valve, just name is different, another kind is used as a vent valve, preventing water hammer ( Water hammer) The role of.

surge relief valve working principle: by pipe hydraulic pressure transmission, makes the main valve slide plate ( The disc) The motions of pilot valve. As long as the upstream pressure below the setpoint of pilot valve, pilot Industrial Valves closed, the upstream pressure above the diaphragm, keep the main valve closed. Once the upstream pressure rose to more than pilot valve set pressure, the pilot Industrial Valves will open, discharge the diaphragm pressure above the water, the main valve opens, a large number of drainage smooth step-down value to slowly shut down, do not produce secondary water hammer. As a water discharge valve, main valve installed on the by-pass of drain, as a holding pressure valve, the main valve series is installed in the pipeline. Best way to install is installed in a horizontal pipe, valve cover up.
