Inside, the fixed position of the lock nut is adjusted through the nut adjustment hole, and the locking position of the lock nut is adjusted according to the different apertures of the pipe port, so as to ensure the tight connection between the positioning shell and the pipe port, and facilitate the detection work.

In the present invention, an elastic sealing layer is provided at the connection position between the positioning shell and the pipe port; the sealing connection cylinder of the device and the pipe port can be adjusted, and the positioning shell and the pipe port must not only be tightly connected, but also To keep the seal, it is necessary to further improve the seal of the device through an elastic sealing layer to reduce measurement errors.

The outer surface of the sealing connection cylinder according to the present invention is evenly distributed with multiple ring-shaped elastic gaskets, and the elastic gaskets are clamped between the pipe port and the sealing connection cylinder; The aperture is adjusted, and when it is adjusted to a proper position, the sealing connection cylinder and the pipe port are tightly connected through the elastic gasket, which is convenient for the pressure delivery pipe inside the sealing connection cylinder to deliver pressure to the inside of the pressure pipeline, which is convenient for detection work.

The pressure delivery pipe of the present invention is provided with a pressure detection gauge, and one end of the sealed connection block connected to the pressure delivery pipe is provided with a rotating positioning block, and the pressure detection gauge is used to detect the air pressure delivered to the inside of the pressure pipeline to determine whether the pressure pipeline is Leakage, while adjusting the position of the sealing connection block in the positioning shell by rotating the positioning block, so as to facilitate the matching of the sealing connection cylinder with pipe ports of different apertures.

The advantages of the present invention are: the present invention can conveniently fix the detection head on pressure pipes with different apertures through the movable adjustable sealing connection block and the positioning shell structure, and match the pressure pipes with different inner diameters through the conical sealing connection cylinder. Complete the sealing work of the pressure pipeline, transmit pressure to the inside of the pressure pipeline through the pressure delivery pipe, and judge whether the pressure pipeline is damaged or leaked. The detection is accurate, the device structure is simple, the operation is convenient, and the application range is wide, which greatly saves the detection cost of the pressure pipeline.
