Product Description

Safety valve: The diaphragm and valve core are pressed against the valve seat by the internal spring. When the pressure in the system pipeline exceeds the preset pressure, the diaphragm and valve core are lifted up, and the medium is discharged to the return pipe and container, on site The pressure can be set in the range of 0-1.0Mpa through the adjustment screw and the pressure gauge in the pipeline. The relief pressure is generally set to be higher than the system pressure 0.1-0.2Mpa. The pressure adjustment of the safety valve is not allowed to exceed the maximum pressure of the pump. The installation is generally as far as possible Near the outlet of the pump, there should be no valve between the pump and the safety valve to protect the safety of the pump and the normal operation of the system.

Back pressure valve: installed on the positive pressure discharge pipeline of the metering pump cargo diaphragm pump to prevent the occurrence of siphon phenomenon and eliminate the change in the dosage caused by the pressure fluctuation of the dosage point, thereby ensuring the accuracy of the pump and removing it on site for adjustment The protective cap on the screw, rotate the adjustment screw, and use the pressure gauge in the pipeline to adjust to the required pressure, and the back pressure can be set within the range of 0-0.6Mpa through the adjustment screw. Used in conjunction with a pulse damper to reduce water hammer damage to the system, maintain a certain constant pressure from the pump outlet to the back pressure valve, and keep the system flow rate constant.
 

Features:

Release the pipeline pressure to ensure the stability of the system pressure.

Protect the safety of the pump and the normal operation of the system.

Used in conjunction with a pulse damper to reduce the harm of water hammer to the system and achieve superior low-vibration mediation effects.

Reduce the peak value of flow rate fluctuations and protect the piping system from the impact of pressure

The diaphragm adopts advanced PTFE+rubber compound technology, which is suitable for almost all corrosive fluids, and the seal is reliable and leak-free.
