Injection Safety Valve usually installed in the positive pressure discharge pipe of the metering pump to prevent the occurrence of siphoning phenomenon and eliminate the change of feeding amount caused by the fluctuation of feeding pressure. Remove the protective cap on the adjusting screw on site and rotate the adjusting screw to adjust the required pressure with the help of the pressure gauge in the pipeline.

The diaphragm and spool of the safety valve are pressed against the valve seat by the internal spring. When the pressure in the system pipeline exceeds the preset pressure, the diaphragm and spool are pushed up and the medium material is discharged to the return pipe and container. At the work site, the pressure gauge in the pipeline can be set within the range of 0-1.0mpa by adjusting the screw. The relief pressure is generally set to be 0.1-0.2mpa higher than the system pressure, and the pressure regulation of the safety valve is not allowed to exceed the maximum pressure of the metering pump.
