[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium (temperature, pressure and flow). According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. The valve equipment used in nuclear power plants undertakes important safety and production functions. Valve failures can cause nuclear power units to become unstable, reduce power or even shut down, posing a major hidden danger to the safe and stable operation of the units.
[0003] After the existing valves are produced, they need to be inspected and tested. The inspected valves need to be tested for sealing using a detection device. Only valves that pass the test can be used. However, the detection device can only detect whether there is a leak in the valve, but cannot accurately find the leak point of the valve. Therefore, personnel need to constantly look for the leak point, which slows down the detection speed and affects the subsequent valves to be tested. Therefore, a valve sealing detection device is proposed to solve the above problems. Utility Model Content

When the two card plates 9 clamp the valve, the air is transported into the valve through the air intake pipe 12 by starting the air pump 11. When the gas enters the valve, the pressure gauge 14 provided above the air intake pipe 12 is used to observe whether there is any leakage in the valve.

Then bubbles will appear at the position of the leak, and the position of the valve leak can be accurately found. The hose 13 is provided, and the hose 13 is made of rubber. The rubber material has good elasticity, high temperature resistance, corrosion resistance and other characteristics. It can be stretched to a certain extent, and when rotating the valve, it only needs to be rotated once, and will not be rotated multiple times.
