Adjust the servo upper and lower plug-in actuator 30 to rotate forward, and the servo upper and lower plug-in actuator 30 drives the upper half joint 37 to move downward to insert into the lower half joint 36 and press it tightly. The displacement sensor 31 monitors the distance between the upper half joint 37 and the lower half joint 36, and the force sensor 32 detects the force applied when the self-sealing joint 35 is pressed. Before testing, the displacement sensor 31 will be calibrated separately for zero position and the pressing distance measurement according to the self-sealing joint installation sample to determine the reference point for judgment.

[0029] a2.

[0031] The process of conducting the flow capacity and flow resistance test of the liquid circulation pressure module 2 includes: b1. When the servo upper and lower plug-in actuator 30 drives the upper half joint 37 to plug with the lower half joint 36, the liquid storage tank 18, the lower half joint 36, and the upper half joint 37 form a liquid circulation loop, and the running speed of the variable frequency pump 21 is adjusted to adjust the flow through the self-sealing joint 35, the flow capacity of the self-sealing joint 35 is measured by the flow meter 22, and the flow resistance of the liquid through the self-sealing joint 35 is measured by the second differential pressure gauge 27. By measuring the pressure loss of the liquid flowing through the inlet and outlet of the self-sealing joint 35, the size of the flow resistance can be determined. When the liquid circulation loop is opened, the liquid storage stop valve 20, the liquid inlet stop valve 25, and the liquid return stop valve 26 are opened, the bypass valve 28 and the purge valve 24 are closed, and the liquid flows out of the liquid storage tank 18 and passes through the liquid storage stop valve 20, the variable frequency pump 21, the flow meter 22, the liquid pressure gauge 23, the liquid inlet stop valve 25, the lower half joint 36, the upper half joint 37, the liquid return stop valve 26, and the liquid storage tank 18 to form a circulation loop.

[0032] b2. When the servo upper and lower plug-in actuator 30 drives the upper half joint 37 to separate from the lower half joint 36, the liquid storage tank 18 forms a circulation passage through the bypass valve 28. When the circulation passage is opened, the liquid storage stop valve 20 and the bypass valve 28 are in an open state, and the liquid inlet stop valve 25, the liquid return stop valve 26, and the purge valve 24 are in a closed state. After the liquid flows out of the liquid storage tank 18, it passes through the liquid storage stop valve 20, the frequency conversion pump 21, the flow meter 22, the bypass valve 28, and the liquid storage tank 18 in sequence to form a circulation passage. The upper half joint 37 and the lower half joint 36 are both equipped with sealing sheets, which automatically cut off the seal when the two are separated, and conduct when the two are plugged in. After the self-sealing joint is separated, a circulation passage is formed through the bypass valve to maintain the flow stability of the circulation system to prevent the flow from causing drastic fluctuations due to the frequent plugging and separation of the self-sealing joint.

When the air supply pressure regulating assembly is in operation, the ball valve 5 and the second air circuit stop valve 8 are in the open state. During the operation of the electric pressure regulating valve 7, the air source 4 acts on the liquid level in the liquid storage tank 18 after passing through the ball valve 5, the gas filter 6, the electric pressure regulating valve 7, and the second air circuit stop valve 8 in sequence.

[0034] The test process of the gas pressure module 1 for the split sealing and the overall sealing of the self-sealing joint 35 includes: c1. Separate sealing test of lower half joint 36: The servo upper and lower plug-in actuator 30 drives the upper half joint 37 to be disconnected from the lower half joint 36, opens the first leak detection valve 11, the second leak detection valve 12, and the first gas stop valve 15, closes the second gas stop valve 16, and the gas is pressurized into the standard container 13 through the first leak detection valve 11, and at the same time, the gas is pressurized into the lower half joint 36 through the second leak detection valve 12 and the first gas stop valve 15. When the first differential pressure gauge 17 detects that the standard container 13 and the lower half joint 36 reach pressure balance, the first leak detection valve 11 and the second leak detection valve 12 are closed, and the differential pressure between the standard container 13 and the lower half joint 36 is compared through the first differential pressure gauge 17. The user can set the differential pressure threshold for judging leakage according to the needs. If the differential pressure after the test exceeds the threshold, it is a leak, otherwise it is not leaking.

[0035] c2. Separate sealing test of the upper joint 37: The servo upper and lower plug-in actuator 30 drives the upper joint 37 to be disconnected from the lower joint 36, opens the first leak detection valve 11, the second leak detection valve 12, and the second gas stop valve 16, and closes the first gas stop valve 15. The gas is pressurized into the standard container 13 through the first leak detection valve 11, and at the same time, it is pressurized into the upper joint 37 through the second leak detection valve 12 and the second gas stop valve 16. When the first differential pressure gauge 17 detects that the standard container 13 and the upper joint 37 reach a pressure balance, the first leak detection valve 11 and the second leak detection valve 12 are closed, and the differential pressure between the standard container 13 and the upper joint 37 is compared through the first differential pressure gauge 17.

[0036] c3. Overall sealing test of self-sealing joint 35: The servo upper and lower plug-in actuator 30 drives the upper half joint 37 and the lower half joint 36 to plug into each other to form a passage, and the first leak detection valve 11, the second leak detection valve 12, the first gas stop valve 15, and the second gas stop valve 16 are opened. The gas is pressurized into the standard container 13 through the first leak detection valve 11, and at the same time, the gas is pressurized into the self-sealing joint 35 through the second leak detection valve 12, the first gas stop valve 15, and the second gas stop valve 16. When the first differential pressure gauge 17 detects that the standard container 13 and the self-sealing joint 35 reach a pressure balance, the first leak detection valve 11 and the second leak detection valve 12 are closed, and the differential pressure between the standard container 13 and the self-sealing joint 35 is compared through the first differential pressure gauge 17.

[0037] Before conducting the split sealing and overall sealing tests, the second gas circuit stop valve 8 must be closed first, and the connection between the liquid circulation pressure module 2 and the self-sealing joint 35 must be disconnected.

[0038] The present invention acts on the self-sealing joint 35 respectively through the gas pressure module 1, the liquid circulation pressure module 2, and the test motion tooling module 3 to achieve insertion and removal force, flow capacity, pressure resistance, overall sealing, split sealing and flow resistance performance tests on the joint.
