7. The container pressure tester according to claim 6, wherein one end of the air inlet pipe (22) positioned in the sealing cover (2) is fixedly connected with a port sleeve (24), the port sleeve (24) is of an annular structure, the port sleeve (24) is communicated with the air inlet pipe (22), and the outer diameter of the port sleeve (24) is larger than that of the air inlet pipe (22).
8. A container pressure tester as claimed in claim 7, characterised in that the pressure gauge (25) has attached to its base a line (26), the line (26) having one end attached to the side of the cuff (24).
9. A container pressure testing method using the container pressure tester according to any one of claims 7 to 8, comprising the steps of:
1) opening the sealing cover (2), and placing the test container into the container frame (5);
2) closing the sealing cover (2), and starting the gear pump (72) to fill water into the cylinder body (1); after the filling, the gear pump (72) reverses to pump out the water; the control circuit board (83) calculates a primary volume value of water according to the water flow value of the flowmeter (74);
3) the handle (23) is rotated to enable the mouth sleeve (24) to be sleeved at the inlet end of the test container, the starting key (85) is pressed down, and the control circuit board (83) controls the gas valve (82) to be opened so as to introduce high-pressure gas into the test container through the gas inlet pipe (22);
4) introducing water vapor into the gap in the cylinder body (1) until the control circuit board (83) receives signals of the vibration sensor (81) and the light receiver (62);
5) after the control circuit board (83) receives signals of the vibration sensor (81) and the light receiver (62), the control circuit board (83) controls the gas valve (82) to be closed so as to enable the gas inlet pipe (22) to stop filling gas, and the reading of the pressure gauge (25) is observed so as to obtain the maximum pressure-bearing value of the container pressure;
6) communicating an air inlet pipe (22) with the external environment to change the air pressure in the test container to a conventional atmospheric pressure value, then starting a gear pump (72), injecting water into the barrel body (1) again, pumping the water out after the water is filled, and calculating a secondary volume value of the water by a control circuit board (83) according to a water flow value of a flowmeter (74); the control circuit board (83) achieves the effect of detecting the volume of the container by comparing the primary volume value with the secondary volume value.
