[0002] Pipe fittings and pipes are a general term for components in pipeline systems that play roles in connection, control, direction change, diversion, sealing, and support. During production, pipe fittings and pipes need to be pressure tested to ensure their normal use and service life in the pipeline system. Pressure testing refers to the process of testing the pressure resistance of pipe fittings and pipes, and this process requires pressure testing instruments.

[0003] However, in the existing pressure testing of pipe fittings and pipes, most of them use a pressure test pump to connect the required accessories such as seals and pressure gauges. The required accessories such as seals and pressure gauges are distributed in a relatively messy manner. When testing the pressure of pipe fittings and pipes, the equipment is relatively complicated and the cost of use is high, which is not conducive to use. Utility Model Content

When pressure testing pipe fittings and pipes, the equipment is relatively complicated, the cost of use is high, and it is not conducive to use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the present invention includes a frame for use, a support leg provided at the bottom end of the frame and a pressing assembly provided at the middle of the top end of the frame, a clamping assembly, an air pump, an air pipe, an air inlet, a connecting pipe, a pressure gauge and a high-pressure pipe fitting to be tested, a clamping assembly is provided at both ends of the top of the frame, an air pump is installed on the inner side of the support leg, an air pipe is connected to the air pump, an air inlet is provided at one end of the air pipe, the air inlet is connected to a connecting pipe, and a pressure gauge is installed at one end of the connecting pipe;

[0006] The clamping assembly includes a fixed block, a screw rod, a screw hole, a handle, a bearing and a pressure block. The fixed block is fixed at both ends of the top of the frame. A screw rod is screwed to the middle of the fixed block. A screw hole is opened at the position of the fixed block corresponding to the screw rod. A handle is provided at one end of the screw rod, and a pressure block is installed at the other end of the screw rod through a bearing. A high-pressure pipe fitting to be tested is provided between the pressure blocks at both ends of the top of the frame.

[0007] Preferably, a corresponding groove is provided in the middle of the pressing block at a position corresponding to the high-pressure pipe to be tested.

[0008] Preferably, a sealing gasket is provided in a groove opened in the middle of the pressing block at a position corresponding to the high-pressure pipe to be tested.
