Description

Technical Field

[0001] The utility model relates to the field of valve testing, in particular to a pump testing tool used for valves. Background Art

[0002] In valve equipment, bypass pipe is usually used as a backup pipe, which can maintain the effective flow of fluid medium on the one hand, and can be equipped with flow control components to play a fluid control function on the other hand. It can isolate equipment such as pressure reducing valves and steam traps when they are damaged or need to be replaced and repaired, or close the main pipe and open the bypass pipe to keep the equipment running.

[0003] In order to ensure the reliable use of valves with bypass pipes, they need to undergo detailed testing before being put into operation, and their structural connection strength, pressure test sealing, flow capacity, etc. are specifically tested according to the purpose of use. At present, when pressure testing the sealing of valves, a plug is usually welded on the bypass pipe to close the bypass pipe. After the whole machine pump test and pressure test are qualified, the plug is cut and removed, and the bypass pipe plane is bored; another example is to add a threaded extension section to the bypass pipe and match it with a threaded plug to close the bypass pipe. After the pump test and pressure test are completed, the thread or the bypass pipe extension part and its threaded extension section are bored. It can achieve the purpose of pump test and pressure test, but its subsequent structural modification and processing, trimming operations are more, the actual operation is complicated, and the testing cost is increased.

The limit portion 41 is arranged to be a wing-shaped structure extending radially along the bypass pipe 2. When the locking member 7 compresses the bracket 4, the limit portion 41 can be closely abutted against the end of the bypass pipe 2, so that the pump test fixture is tightly connected as a whole.

[0041] In some embodiments, see Figure 1 The pump inspection tooling also includes a gasket 8, which is sleeved on the connecting member 6, one side of the gasket 8 abuts against the locking member 7, and one side of the gasket 8 abuts against the wall of the inner cavity of the valve body 1, and the locking member 7 is suitable for crimping the gasket 8 in the inner cavity of the valve body 1. The gasket 8 can be set as a sealing gasket.

[0042] In this embodiment, see Figures 1 to 4 , the valve body 1 is provided with a flange side 3, and the flange side 3 and the bypass pipe 2 are arranged at intervals.
