Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in the attached

drawings

1 and 2, the utility model comprises a pipe body 1, wherein a first through hole 2 is arranged at the center in the pipe body 1 and penetrates through the pipe body 1 along the axial direction; the two ends of the tube body 1 are respectively provided with a connecting end 3, the radial wall of the connecting end 3 is provided with a second through hole 4, and the second through hole 4 is communicated with the first through hole 2; the hole walls of two ends of the first through hole 2 are respectively provided with internal threads 5, the internal threads 5 are positioned at the connecting end 3, one end of each internal thread 5 is flush with the end surface of the connecting end 3, and the other end of each internal thread 5 is flush with the hole wall of the second through hole 4; the inner thread can be rotatably connected with a plug, and when water flow needs to flow out of or into the second through hole, the water flow only needs to be fixed with the inner thread through the plug; an annular groove 6 for installing an O-shaped sealing ring is arranged on the radial wall of the connecting end 3, and the annular groove 6 is positioned on one side of the second through hole 4, so that the sealing performance between the pipe body and the high-pressure water pipe is greatly improved; the radial wall of the connecting end 3 is provided with a clamping groove 7, and the clamping groove 7 is positioned at the end face of the connecting end 3. The utility model discloses an application principle does: as shown in fig. 3, the pipe body 1 is sleeved with the connecting port of the high-pressure water pipe through the connecting end 3, and the clamping groove 7 is clamped through the clamping strip 12, so that fixed connection is realized, meanwhile, the hole walls of the two ends of the first through hole 2 are blocked by the plugs, the water through holes 11 formed in the radial end surface of the connecting port of the high-pressure water pipe correspond to the water through grooves formed by the second through holes 4, at this time, one end surface of the connecting port of the high-pressure water pipe abuts against the stepped groove 8, and the other end surface abuts against the end surface of the clamping strip 12; however, one connecting end 3 can be connected in the above mode, the other connecting end is directly axially inserted into the connecting end through a common high-pressure pipeline, and the O-shaped sealing rings are arranged on two sides of the second through hole, so that the purpose of water passing can be achieved as long as the plug is removed.
