The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0029] Please see Figure 1-8 This utility model provides a connecting valve detection device, including a workbench 10, which has a hollow structure. An inlet and outlet water pipe 110 is provided on one side of the workbench 10. The inlet and outlet water pipe 110 is used to discharge or inject water. A valve is provided on the inlet and outlet water pipe 110, which can open or close the inlet and outlet water pipe 110.

[0030] A slot 101 is provided on the top of the workbench 10. A first horizontal pipe 210 and a second horizontal pipe 220 are arranged horizontally in the slot 101. A transport pump 30 is provided on one side of the workbench 10. The inlet pipe 310 of the transport pump 30 is connected to the interior of the workbench 10. The outlet pipe 320 of the transport pump 30 is connected to the first horizontal pipe 210. Two first connecting pipes 211 are vertically connected to the top of the first horizontal pipe 210. The two first connecting pipes 211 are arranged parallel to each other. A connecting plate 40 is connected to the end of the first connecting pipe 211.

[0031] An opening 102 is provided at the bottom of the inner cavity of the first tank 101. The opening 102 allows water in the first tank 101 to flow into the worktable 10. At the same time, it allows the pressure on the worktable 10 to be consistent with the external pressure.

[0032] The right side of the second horizontal tube 220 is connected to the interior of the workbench 10 via a connecting tube 221. Two second connecting tubes 222 are vertically connected to the top of the second horizontal tube 220. The two second connecting tubes 222 are parallel to each other. Each of the two second connecting tubes 222 has a first connecting port 2221 at its top. A second connecting port 2222 is provided on the side of the two second connecting tubes 222 that are close to each other. A connecting plate 40 is connected to both the first connecting port 2221 and the second connecting port 2222.

[0033] Flow meters 70 are connected to both second connecting pipes 222.

[0034] The second connecting pipe 222 is 'T' shaped with a 90-degree rotation. An adjusting ball 50 is installed inside the second connecting pipe 222. The adjusting ball 50 is located at the bend in the inner cavity of the second connecting pipe 222. The adjusting ball 50 has a 'T' shaped connecting groove 501. The adjusting ball 50 can be rotated by adjusting handle 510. The end of adjusting handle 510 is fixedly connected to adjusting ball 50. The adjusting handle 510 and the second connecting pipe 222 are sealed and rotatably sleeved. The second connecting pipe 222 does not affect the rotation of adjusting handle 510 and will not leak.

[0035] The outer wall of the connecting plate 40 is threaded, and the top of the connecting plate 40 is provided with a groove 401, which can hold a sealing ring. When the connecting plate 40 is not in use, a sealing cap 410 is threaded onto the connecting plate 40. The sealing cap 410 is adapted to the top of the connecting plate 40 and is sealed by the sealing ring.

[0036] Each of the two connection ports on the connecting valve 60 is provided with a movable connecting threaded sleeve 610 for connecting the connecting disc 40.

[0037] The working principle and usage process of this utility model: The U-shaped connecting valve 60 is installed in different positions according to its type. When testing the U-shaped connecting valve 60, it is installed in the following positions: Figure 3 As shown, the liquid inside the workbench 10 is pumped to the first transverse pipe 210 by the transport pump 30 at a fixed power. The liquid inside the first transverse pipe 210 enters the second transverse pipe 220 through the first connecting pipe 211, the U-shaped connecting valve 60, and the second connecting pipe 222. After the liquid passes through the second connecting pipe 222, the flow rate data is obtained by the flow meter 70. The detected flow rate data is compared with the flow rate data of the U-shaped connecting valve 60 to determine whether the U-shaped connecting valve 60 is working properly. The liquid then returns to the workbench 10 through the connecting pipe 221. If a leak occurs, the leaked liquid enters the first tank 101 and enters the workbench 10 through the opening 102.

[0038] When testing the linear connecting valve 60, the right-side U-shaped connecting valve 60 is disassembled, and a sealing cap is installed on the right-side first connecting pipe 211. The adjusting handle 510 on the right-side second connecting pipe 222 controls the sealing ball 50 to rotate counterclockwise by 90 degrees (e.g., Figure 8 As shown), the sealing ball 50 on the left second connecting pipe 222 is rotated 90 degrees clockwise; the two ports of the linear connecting valve 60 are installed to the two No. 2 connecting ports 2222. The liquid passes through the first horizontal pipe 210, the left first connecting pipe 211, the U-shaped connecting valve 60, the left second connecting pipe 222, the linear connecting valve 60, the right second connecting pipe 222, and the second horizontal pipe 220 in sequence, and returns to the workbench 10 through the connecting pipe 221; the flow rate data of the liquid passing through the second connecting pipe 222 is obtained by the flow meter 70. The detected flow rate data is compared with the flow rate data of the good linear connecting valve 60 to determine whether the linear connecting valve 60 is good.
