Embodiment Construction

[0021] The invention provides a double-layer fastening high-pressure flushing water gun. The gun head 1 of the water gun has a water outlet pipe 2, the uppermost end of the gun head 1 is a water outlet 3, and the middle part of the gun head 1 is a sleeve part 4. The lower end of the connection part 4 is a fastening end 5, and a water pipe can be sleeved on the fastening end 5.

[0022] The surface of the socket part 4 is provided with threads.

[0023] A fastening sleeve 6 is sleeved on the gun head 1, and the upper part of the fastening sleeve 6 is provided with an internal thread, which is socketed with the sleeve part 4 through a thread, and the lower half of the fastening sleeve 6 is sleeved on the fastening on the top half of end 5.

[0024] The lower end of the fastening sleeve 6 is arranged to be tightened inward in an arc shape.

[0025] The surface of the fastening end 5 is set in a tooth shape.

[0026] The inner diameter of the water outlet pipe 2 is the same as ...

Abstract

The invention provides a double-layer fastened high-pressure washing water gun. A gun head of the water gun comprises a water outlet pipeline and a water outlet is arranged at the topmost end of the gun head; a sleeve joint part is arranged in the middle of the gun head and a fastening end is arranged at the lower end of the gun head; and a water pipe can be sleeved at the fastening end. According to the double-layer fastened high-pressure washing water gun disclosed by the invention, the water gun and the water pipe have higher fastening performance and provide great water outlet pressure; the water outlet pressure can reach to 10 MPA so that the water gun can efficiently clean the inner wall of a steel pipe and remove impurities including oxide skin and the like in the steel pipe; and therefore, the quality of the inner wall of the steel pipe is improved and the subsequent machining is easy to realize.

Description

technical field [0001] The invention relates to the field of flushing water guns, in particular to a double-layer fastening high-pressure flushing water gun for flushing the inner surface of steel pipes. Background technique [0002] After the steel pipe is used, there will be sundries such as oxide skin on the internal surface. Using the flushing water gun can effectively clean the internal surface of the steel pipe, which is convenient for subsequent processing, but the water pressure of the flushing water gun cannot reach the ideal value, so that the washing effect is not enough. Steel pipe The internal surface quality of the rinsing water gun can not meet the required value of the subsequent processing, and the water pressure is increased, and the nozzle of the flushing water gun is easy to fall off. [0003] Therefore, it is necessary to provide a flushing water gun that can achieve a large water outlet pressure and keep the gun head of the flushing water gun firmly fr...
