[0017] By adopting the above technical scheme, when the mouth of the tank body is embedded in the sealing hole, the inner circle of the sealing ring bag presses against the outer peripheral surface of the mouth of the tank body to achieve preliminary sealing of the mouth of the tank body. At the same time, the mouth of the tank body presses against one end face of the piston and overcomes the elastic force of the elastic member to drive the piston to slide in the direction close to the sealing flow channel.

When the pressure resistance test of the tank body is completed, the user presses the end of the air leakage pipe to drive the air leakage pipe to slide in the direction close to the air leakage hole. The elastic block is squeezed and deformed by the air leakage pipe, so that the sealing effect of the elastic block on the air leakage hole disappears, and the air in the sealing ring bag is discharged from the air leakage pipe through the air leakage hole, thereby achieving pressure relief of the sealing ring bag, reducing the contact force between the tank body and the sealing ring bag, thereby reducing the wear between the sealing ring bag and the tank body, and extending the service life of the pressure resistance testing equipment for pressure vessels.

[0023] By adopting the above technical solution, a detection ring surrounds the outer circumference of the tank body, and multiple detection impellers are connected to the inner wall of the detection ring at intervals. When the air in the tank body overflows from the cracks on the surface of the tank body, the overflowing air impacts the detection impeller blades, driving the detection impeller to rotate, and the detection gear engages the rack, driving the rack to slide toward the direction close to the contact switch. The contact switch abuts the rack and is turned on, and the warning light is energized to illuminate, thereby prompting the user to the location of the cracks on the tank body surface, thereby further improving the accuracy of the tank pressure resistance test.
