Safety precautions for use and installation of sanitary diaphragm valve

Safety precautions for use and installation of sanitary diaphragm valve the function of sanitary diaphragm valve actuator (such as hydraulic cylinder and hydraulic motor) is to convert the pressure energy of liquid into mechanical energy, drive the load to make linear reciprocating motion or rotary motion The control element (i.e various hydraulic valves) controls and regulates the pressure, flow and direction of liquid in the hydraulic system According to the different control functions, the hydraulic valve can be divided into village force control valve, flow control valve and direction control valve     Pressure control valve is divided into benefit flow valve (safety valve), pressure reducing valve, sequence valve, pressure relay, etc.; flow control valve includes throttle valve, regulating valve, diverting and collecting valve, etc.; direction control valve includes one-way valve, hydraulic control one-way valve, shuttle valve, reversing valve, etc according to different control modes, hydraulic valve can be divided into switch type control valve, constant value control valve and proportional control valve Auxiliary components include Oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level and temperature gauge, etc Hydraulic oil is the working medium of transmitting energy in the hydraulic system There are various kinds of mineral oil, emulsion and synthetic hydraulic oil, etc It is light in weight, small in volume and easy to be installed between the flanges The valve is composed of two semicircle springs and the plate surface The spring fixed on the valve body by the pin deforms to close the valve plate The fluid pressure makes the opening spring deform quickly, which can protect the pipeline from water hammer damage Notes for installation of sanitary diaphragm valve: when placing the pipeline, attention shall be paid to ensure that the flow direction of the wafer check valve is consistent with the flow direction and is installed in the vertical pipeline For horizontal pipeline, vertically place the wafer check valve and use an expansion pipe between the wafer check valve and the butterfly valve Do not connect it directly with other valves within the operating radius of the sanitary diaphragm valve plate to avoid adding pipe joints and obstructions Do not install a reducer in front or behind the wafer check valve and install the wafer check valve near the elbow When installing the check valve, pay attention to leaving enough space When installing the wafer check valve at the outlet of the water pump, at least six times of the valve diameter will flow out to ensure that the butterfly plate Zui is finally affected by the fluid.
