Air gun for removing dust in hole

Abstract

The invention discloses an air gun for removing dust in a hole. The air gun for removing the dust in the hole comprises a gun body (5) and a nozzle (11), wherein the end of a gun handle of the gun body (5) is an air inlet end (2), an internal threaded hole (16) is formed in the air inlet end (2), multiple anti-skid grooves (3) are formed in the circumferential surface of the gun body (5), the front end of a gun part of the gun body (5) is an air outlet end (9), a threaded connector (12) is arranged at the air outlet end (9) and is connected with the nozzle (11), the nozzle (11) is of a conical structure with one end big and the other end small, a rotary shaft (8) is further arranged on the gun part of the gun body (5), the rotary shaft (8) is connected with a spanner (13), the inner side of the spanner (13) is connected with a reset spring rod (14), and the rotating structure that the spanner (13) rotates with the rotary shaft (8) as the axis is formed. According to the air gun for removing the dust in the hole, comprehensive dedusting of a valve can be achieved, the dust removal efficiency is high, and the practicability is high.

Description

technical field [0001] The present invention relates to an air gun, and more specifically relates to an air gun for dust removal in holes. Background technique [0002] Because the valve products need to meet high sealing performance, before the valve products are assembled, it is necessary to clean the valve products, especially the three sealing parts of the valve core, valve seat and valve stem, so as to ensure the sealing performance after assembly. Valve products have a high sealing performance. Because some small-diameter valve products have some small-diameter through holes, the sundries in the through holes are not easy to be blown out, which makes the dust removal not thorough enough and affects the sealing performance of the valve products. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, provides an air gun for dust removal in the hole, and solves the problem that the dust removal of the small-diameter through-hole in...
