Inlet and outlet valve measurement method
When there are calipers at home, we only need to measure the steel bigouter diameter and total height of the valve.
Outer diameter: refers to the outer diameter of the steelbigouter diameter or the connection between the steel and the outer diameter of the check valve.
Height: Refers to the overall height of thevalve (if it is protruding, it should be measured in full).
What are the symptoms of a broken AR valve?
The ARvalve of our car washing machine is divided into water inlet and outlet valves. If the elasticity of the ARvalve is not good, or the sealing ring is aging, the car washing machine will have insufficient pressure, the water will shake violently, the water will be slow, and the water will be small, etc. ( Insufficient pressure in the car washer is not only affected by the ARvalve).
How many check valves should be replaced?
Replaced the AR valve and still useless, what should I do?
If the problem is still not solved after replacing the AR valve,It does not mean that the AR valve has a quality problem,we have to eliminate other situations, such as air leakage from the water inlet, water leakage from the water gun, water leakage from the high-pressure pipe, and water seal wear and unsealing, etc. We have to go to check
