Technical Field

[0001] This utility model relates to the field of pipeline pressure testing technology, and in particular to a rapid pressure testing fixture for steel pipe connectors. Background Technology

[0002] In pipeline construction, the sealing test of steel pipe connectors is a crucial step in ensuring project quality. Traditional pressure testing methods typically employ welding or flange connections, requiring specialized equipment to seal both ends of the pipe before injecting the medium through a pressure pump for pressure testing. This method is widely used in pipeline acceptance and maintenance in the oil, natural gas, and municipal water supply and drainage sectors, and is a standard technique for testing the sealing performance of pipeline connections.

[0003] Existing pressure testing equipment suffers from cumbersome operation and low efficiency. Each test requires welding or bolting, which is not only time-consuming and labor-intensive but can also damage the pipeline itself. Especially in situations requiring frequent testing, traditional methods are costly to install and cannot achieve rapid disassembly and assembly. Utility Model Content

A insertion groove is provided on one side of the fixing block, and a connecting block is provided on the side of the fixing block near the insertion groove. A insertion block is fixedly connected to one side of the connecting block, and the insertion block is inserted into the insertion groove. Limiting mechanisms are provided on both sides of the fixing block to fix the insertion block in the insertion groove. A first through groove and a second through groove are respectively provided on the fixing block and the connecting block.

[0006] As a further improvement of this utility model, the limiting mechanism includes a fixed frame fixedly connected to one side of the fixed block, a movable plate slidably disposed within the fixed frame, a limiting groove formed on one side of the insertion block, a limiting block fixedly connected to one side of the movable plate, the limiting block passing through the insertion groove and inserted into the limiting groove, a spring fixedly connected to the other side of the movable plate, the other end of the spring fixedly connected to the inner wall of the fixed frame, a pulling block disposed on the outer side of the fixed frame, one end of the pulling block passing through the fixed frame and through the spring, and finally fixedly connected to the movable plate.

[0007] As a further improvement of this utility model, a threaded connecting pipe is fixedly connected to the other side of the connecting block, and a water pump is threadedly connected to the threaded connecting pipe. The inside of the threaded connecting pipe is connected to the second through groove.

[0008] As a further improvement of this utility model, a sealing groove is also provided on one side of the fixing block between the first through groove and the insertion groove, and a sealing block is fixedly connected to one side of the connecting block, and the sealing block is inserted into the sealing groove.

[0009] As a further improvement of this utility model, the first through groove and the second through groove are the same size and their positions correspond.

[0010] As a further improvement of this utility model, the test steel pipe has the same diameter as the engineering steel pipe.

[0011] The beneficial effects of this utility model are: The quick-connector allows for rapid docking of the test steel pipe and the engineering steel pipe.
