Today, I will introduce you to the car knowledge of how to adjust the pressure regulating valve of the car washing machine. At present, the regulating valve on the car washing machine is actually a pressure reducing valve. When the outlet pressure exceeds the set pressure, the pressure relief valve opens and the water returns to the water inlet of the pump through the pressure relief valve. Next, Bian Xiao will tell you how to adjust the pressure regulating valve of the car washer.

How to adjust the pressure regulating valve of car washing machine: working principle

High-pressure air valves are also needed in many places in general life. This device is actually designed for the flow of liquid and gas, and its operation is mainly controlled by coils. When the coil is energized, a magnetic field will be generated, and the plunger in the coil will also move. The valve is designed to close any trigger, and when the current is removed from the coil, it will return to the closed state.

How to Adjust the Pressure Regulating Valve of Car Wash Machine: Advantages

1, the advantages of high-pressure ball valve Let's take a closer look. First of all, among all types of valves, the fluid resistance of the ball valve is the smallest, and even the variable diameter ball valve is quite small. Switching is fast and convenient. As long as the valve stem rotates 90, the ball valve will be fully opened or closed, and it is easy to realize rapid opening and closing. Good sealing performance, the sealing ring of ball valve seat is generally made of elastic materials such as PTFE, which is easy to ensure sealing. The sealing force of ball valve increases with the increase of medium pressure.

2. Another advantage of high-pressure ball valve is that its valve stem is very well sealed, so when the ball valve is opened and closed, the valve stem only rotates. Therefore, the packing seal of the valve stem is not easy to be damaged, and the sealing force of the inverted seal of the valve stem increases with the increase of medium pressure. The opening and closing of the ball valve only rotates 90 degrees, which is easy to realize automatic control and remote control. The ball valve can be equipped with pneumatic device, electric device, hydraulic device, gas-liquid linkage device or electro-hydraulic linkage device.
