[0022] In a preferred embodiment, the number of adjustment holes 5 is several, and the several adjustment holes 5 are respectively arranged on the outer wall of the telescopic rod 4 and the outer wall of the fixed pillar 3. Through the several adjustment holes 5 on the device, the fixed pillar 3 and the telescopic rod 4 on the device are first telescoped, and then the adjustment holes 5 on the outer walls of the telescopic rod 4 and the fixed pillar 3 are corresponding, so that the fixed pillar 3 and the telescopic rod 4 on the device are fixed by using the fixed connecting rod 6 passing through the adjustment hole 5.

[0023] In a preferred embodiment, the inner diameter of the sample water pipe 7 ranges from 300 to 1650 mm, and the test length of the sample water pipe 7 is 1000 mm to 2000 mm. The sample water pipe 7 on the device changes its length and diameter as required, and meets the pressure gauge range of 0-0.6 MPa, minimum resolution of 0.001 MPa, accuracy: level 1.0, upper and lower limits can be set to automatically maintain constant pressure.

[0025] The outer walls of both sides of the sample water pipe 7 need to be polished and smooth first, and then the sealant 8 is evenly applied to form a sealing ring. The outer walls of both sides of the sample water pipe 7 on the device need to be polished and smooth first, so that the polished sample water pipe 7 is applied with sealant 8 on the outer edges of the outer walls on both sides, so that it forms a complete seal, thereby making the device convenient for subsequent operations and preventing leakage.

[0026] In a preferred embodiment, the number of fixed pillars 3, telescopic rods 4, and fixed connecting rods 6 is two, and the fixed pillars 3, telescopic rods 4, and fixed connecting rods 6 are symmetrically arranged at the bottom of the sample water pipe 7.

In this process, when the nuts 14 are used to tighten the screws 13, they need to be tightened one by one in a diagonal manner, so that the two sealing plates 9 on the device are relatively parallel and not easy to leak.

[0028] When the device is in operation: open the water inlet valve, close the pressure valve, and open the exhaust valve at the same time. If water leakage is found on the closed surface during this process, stop filling water. Manually increase the pre-tightening force of the nut 14 or other sealing methods until the cover stops leaking.

[0029] When water overflows from the exhaust hole, it means the water pipe is full. Close the exhaust valve, plug in the power supply, set the digital pressure gauge to the required pressure, close the water inlet valve, open the boost valve, and enter the automatic pressure maintaining time.

[0030] When the pressure holding time is over, turn off the power, open the water valve to drain the water, operate the movable plate to separate it, remove the test tube, and organize the test report.

Then, through the mutual use of the sample water pipe 7, the sealing plate 9, the screw 13 and the nut 14 on the device, both sides of the sample water pipe 7 on the device are first polished and smoothed, and then the sealant 8 is applied to form a seal. When the two sealing plates 9 are installed on both sides of the sample water pipe 7, the screws 13 and the nuts 14 are tightened one by one in a diagonal manner, so that the two sealing plates 9 on the device are relatively parallel and not easy to leak, and then the sealant 8 is used to increase the seal.
