Pressure relief valve (pressure relief valve) is a common protection device for high pressure blower.Its principle is to change the shaft power of high pressure blower motor
by reducing (increasing) the pressure of high pressure blower according to the corresponding relationship between shaft power and pressure of motor, thus effectivel
protecting motor.

The pressure relief valve can be used in both positive and negative pressure directions, i.e. the air inlet and outlet of the high pressure blower, and is generally connected to the front end of the vacuum tube through three-way or other pipelines. The pressure relief valve of the high pressure blower should be far away from volatile grease and gas. When installing the pressure relief valve, be sure to pay attention to the arrow direction on the vacuum tube and the installation direction of positive pressure and negative pressure. The normal operating temperature is-10 ~ 120 degrees. It mainly increases or decreases the pressure by rotating the screw of the relief valve, thus achieving the natural protection of the high pressure blower.
