Description

Technical Field

[0001] The invention relates to the technical field of sealing detection, and in particular to a quick sealing joint device. Background Art

[0002] The car radiator is also called the car water tank. Generally, when the radiator is filled with water, the joint of the hose is most likely to crack and leak. At this time, you can use scissors to cut off the damaged part, then reinsert the hose into the radiator water inlet joint and tighten it with a clip or wire. If the crack is in the middle of the hose, you can use tape to wrap the leaking crack. Wipe the hose clean before wrapping it. After the leaking part is dry, wrap the tape around the leaking part of the hose. Since the water pressure in the hose is high when the engine is working, try to wrap the tape as tightly as possible. If you don't have tape on hand, you can also wrap plastic paper around the crack first, and then cut the old cloth into strips and wrap it around the hose. Sometimes the hose has a large crack and may still leak after wrapping it. At this time, you can open the radiator cap to reduce the pressure in the waterway and reduce leakage.

[0003] The automobile water tank is an important device used in the automobile air conditioning refrigeration system. The quality of its product directly affects the effect of the automobile refrigeration system.

The rubber pad 6 is deformed under the action of pressure, and then the inner diameter of the rubber pad 6 becomes smaller and fits tightly with the outer diameter surface of the product to be tested 7. Then, the gas is inflated through the air inlet A on the handle 1. The gas passes through the through holes of the handle 1 and the pressure block 3 and then enters the inner cavity of the product to be tested. After a certain amount of gas is rushed in, the pressure in the inner cavity of the product to be tested 7 increases. When the required pressure is reached, the inflation is stopped and the pressure is maintained for a certain period of time. The change in the pressure value of the inner cavity of the product to be tested is observed, and then it is determined whether the air tightness of the product to be tested 7 is qualified.
