Description

Technical Field

[0001] The utility model relates to the technical field of building equipment detection, and more specifically to a one-way valve integrity detection device. Background Art

[0002] The one-way valve in the deepwater jacket grouting system is made of steel valve body and plastic valve core. The one-way valve is connected to the pipeline by welding. During the welding process, the temperature of the valve body needs to be controlled to prevent the valve core from melting and failing due to the heat generated by continuous welding. After the one-way valve fails, the fluid in the pipeline cannot enter the skirt pile sleeve through the one-way valve, and the grouting cannot be completed. The damaged valve core needs to be urgently replaced by airlift from abroad to ensure the realization of the grouting system function. The failure of the one-way valve will not only cause project cost losses, but also delay the construction period. Therefore, it is necessary to test the integrity of the one-way valve after welding it to the pipeline.

[0003] After searching, it is found that the patent document with the existing publication number CN215573633U provides a one-way valve integrity detection device, which is only suitable for the integrity test of small-sized one-way valves. In this field, the deep-water conductor rack is large in size and usually built horizontally. Most of the one-way valves are more than 100 meters above the ground, making it difficult to use conventional means to perform integrity tests. Since the pressure test of the grouting system is in the later stage of the project, once the one-way valve is found to be damaged, it will take a long time and costly to re-purchase the one-way valve and parts, which will affect the construction period.

[0004] In view of this, we propose a one-way valve integrity detection device. Utility Model Content

[0029] As a preferred embodiment of the present application, a rubber cushion layer is fixedly provided on one side of the first limiting plate 5 close to the detection tube 2 .

[0030] As a preferred embodiment of the present application, the end of the air intake pipe 13 is provided with threads.

[0031] As a preferred embodiment of the present application, the air outlet 9 is far away from the center of the baffle 8.

[0033] Working principle:

[0034] The detection tube 2 is welded to both sides of the one-way valve body 1, and the detection tube 2 is placed on the pipe shoe bracket 4, and the air intake pipe 13 is connected to the air supply line through the thread at the end of the air intake pipe 13.

[0035] Turn the adjusting screw 7, push the baffle 8 close to the detection tube 2, and push the detection tube 2 to move, so that the two detection tubes 2 are respectively in contact with the first limit plate 5 and the baffle 8. Then push the detection cylinder 11 into the air outlet 9, and supply air to the air inlet pipe 13 through the air supply line, and the air supply pressure is controlled at 5 bar. If the air outlet of the one-way valve body 1 is located on the side of the baffle 8, observe whether there is gas discharged from the air outlet 9. When the detection cylinder 11 in the air outlet 9 is pushed outward and gas is discharged from the exhaust groove 12 on the outer wall of the detection cylinder 11, it means that the passability of the one-way valve body 1 is good. If the air outlet of the one-way valve body 1 is located on the side of the first limit plate 5, observe whether there is gas discharged from the air outlet 9. If the position of the detection cylinder 11 in the air outlet 9 does not change, it means that the one-way performance of the one-way valve body 1 is good.

[0036] After the passability or unidirectionality test of the one-way valve body 1 is completed, the adjusting screw 7 is rotated in the opposite direction to remove the baffle 8 from the end of the detection tube 2, and the two ends of the one-way valve body 1 are replaced by the rotating seat 10, and then the unidirectionality or passability of the one-way valve body 1 is tested.
