Description

Technical Field

[0001] This utility model relates to the field of locomotive radiator technology, and in particular to a water pipe pressure testing fixture. Background Technology

[0002] During the production and maintenance of locomotive radiators, if a leak occurs in the radiator's water pipe, it needs to be repaired by plugging both ends of the leaking pipe. When a leak occurs in the radiator's water pipe, we first need to conduct an overall pressure test or determine the approximate area of ​​the leak through observation. Then, we need to test the pressure of several water pipes in this area one by one to find the leaking pipe before we can repair and plug it. The operation is complicated and requires a lot of manual labor. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide a tooling for pressure testing of radiator water pipes that can conveniently and quickly locate leaks in the water pipes.

[0004] The technical solution adopted by this utility model is a pressure testing fixture for a radiator water pipe, including a set of end heads and a rear seat. The set of end heads has at least two ends. The end head is in the shape of a stepped shaft, with an air inlet hole inside. The thin shaft section at the front end is the air inlet head. The air inlet head is compatible with the radiator water pipe. The end face of the shaft shoulder is provided with an O-ring groove, and the end head tail is machined with an internal thread. The rear seat is also stepped in shape, with an air intake hole inside; the thin shaft section at the front end has an external thread that matches the internal thread at the end, and the shoulder end face also has an O-ring groove, and the rear end of the rear seat has an internal thread.

[0005] The internal thread at the tail of the rear seat is a tapered thread.

[0006] The beneficial effects of this utility model are that it can easily and quickly locate leaking water pipes, improve production and maintenance efficiency, and reduce production costs. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] The radiator water pipe pressure testing fixture disclosed in this utility model consists of two parts: an end 1 and a rear seat 2. The end includes a set, with each set containing no fewer than two ends. Figure 1 As shown.

[0014] The front end of end 1 is equipped with an air inlet head 102, which can be inserted into the radiator water pipe. Different end 1s have different models of air inlet heads 1 to accommodate different radiator water pipes. The outer contour of end 1 is a stepped shaft shape, and the shoulder end face has an O-ring groove for use with an O-ring to seal the pipe end. An air inlet hole is provided internally. A connecting thread is provided at the tail end for connecting to a rear seat, such as... Figure 2 As shown.

[0015] The front end of the rear seat 2 is machined with connecting threads for connecting to the end head 1; the rear seat 2 is also in the shape of a stepped shaft, and the end face of the shaft shoulder is also provided with an O-ring groove for use with an O-ring for sealing between it and the end head; the interior is also provided with an air inlet hole; the tail is provided with a tapered thread for connecting the air inlet connector and its pipeline.

[0016] During use, select the appropriate end 1 and connect it to the rear seat 2 according to the pipe diameter. Insert the air inlet 102 into the water pipe 6, ensuring the end face of the shoulder of end 1 fits against the radiator, and the O-ring forms an effective seal. Inject low-pressure compressed air into the radiator pipe through the air inlet hole to check for leaks.

[0017] The tooling structure of this application is simple, easy to use and adjust, saving time and effort. It can meet the requirements for pressure testing of radiator water pipes, reduce the labor intensity of operators, greatly improve production and maintenance efficiency, reduce auxiliary working hours, and save production costs.
