Abstract
The utility model discloses an adjustable air intake sand blasting machine nozzle belongs to sand blasting machine nozzle field. It includes venturi nozzle, seal cover, adjusting sleeve, venturi tube nozzle inlet end is equipped with the installation screw thread, and the middle part is equipped with the regulation external screw thread, has seted up a plurality of air intakes around the exit end near the venturi nozzle, the seal cover is fixed within adjusting sleeve, and both overlap together on the venturi nozzle, and the seal cover can closely cover the air intake, the adjusting sleeve inner wall is equipped with the regulation internal thread, adjusts the internal thread and meshes mutually with regulation external screw thread on the venturi nozzle. Through set up the air intake on the venturi nozzle, use adjusting sleeve and seal cover dynamic overlay air intake, adjust the air intake size for corresponding change can take place for the outlet velocity of sandblast area and medium, improves the quality and the efficiency of abrasion blasting, simple structure moreover, convenient operation.
Description
Technical field
This utility model relates to a kind of adjusting air inlet mouth nozzle of sand spraying machine, belongs to nozzle of sand spraying machine field.
Background technology
Sandblasting machine is employing compression air is power, and with abrasive material for medium, compression air flows through formation negative pressure in spray gun, abrasive material injection to nozzle at high speeds is ejected into and need to be processed surface of the work, to hold as fulcrum, workpiece is sprayed, the surface of workpiece can be made to produce the equipment of favourable change. Wherein nozzle of sand spraying machine is important parts, and it is directly connected to quality and the efficiency of sandblasting processing. At present, nozzle of sand spraying machine on market is generally adopted Venturi nozzle, Venturi nozzle internal structure is divided into contraction section, flat segments, diffuser three part, its dynamic performance is better than straight hole nozzle, vortex phenomenon is obviously improved, and the pressure loss substantially reduces, and under identical pressure condition, relatively the muzzle velocity of straight hole nozzle abrasive material is enhanced about more than once, work efficiency improves 15 40%, and abrasive material consumption reduces by 20%. But it still has some defects, Venturi nozzle shape is fixed, and when input pressure state is constant, its sandblasting area and the muzzle velocity of medium are fixing, when requiring sandblasting area and blasting pressure to change, this nozzle can not change flexibly.
Utility model content
Technical problem to be solved in the utility model is in that: provide a kind of adjusting air inlet mouth nozzle of sand spraying machine, the problem it solving the muzzle velocity changing sandblasting area and medium flexibly.
Technical problem to be solved in the utility model takes techniques below scheme to realize:
A kind of adjustable air inlet nozzle of sand spraying machine, it includes Venturi nozzle, sealing shroud, adjusting sleeve pipe, described Venturi nozzle arrival end is provided with installation screw thread, middle part is provided with adjustment external screw thread, port of export surrounding near Venturi nozzle offers some air inlets, described sealing shroud is fixed within adjusting sleeve pipe, both are enclosed within Venturi nozzle together, sealing shroud can close over air inlet, described adjusting sleeve pipe inwall is provided with adjustment female thread, regulates female thread and is meshed with the adjustment external screw thread on Venturi nozzle.
As preferred embodiment, described sealing shroud adopts elastomeric material.
As preferred embodiment, described Venturi nozzle adopts boron carbide material to make.
The beneficial effects of the utility model are: by offering air inlet on Venturi nozzle, use adjusting sleeve pipe and sealing shroud dynamic coverage air inlet, regulate air inlet size, corresponding change can be there is in the muzzle velocity making sandblasting area and medium, improve quality and the efficiency of sandblasting processing, and simple in construction, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: Venturi nozzle 1, sealing shroud 2, adjusting sleeve pipe 3, screw thread 11 is installed, regulates external screw thread 12, air inlet 13, regulate female thread 31.
Detailed description of the invention
In order to technological means of the present utility model, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1, a kind of adjustable air inlet nozzle of sand spraying machine, it includes Venturi nozzle 1, sealing shroud 2, adjusting sleeve pipe 3, Venturi nozzle 1 arrival end is provided with installation screw thread 11, middle part is provided with adjustment external screw thread 12, port of export surrounding near Venturi nozzle 1 offers some air inlets 13, sealing shroud 2 is fixed within adjusting sleeve pipe 3, both are enclosed within Venturi nozzle 1 together, sealing shroud 2 can close over air inlet 13, adjusting sleeve pipe 3 inwall is provided with adjustment female thread 31, regulates female thread 31 and is meshed with the adjustment external screw thread 12 on Venturi nozzle 1. Sealing shroud 2 adopts elastomeric material. Venturi nozzle 1 adopts boron carbide material to make.
By offering air inlet 13 on Venturi nozzle 1, use adjusting sleeve pipe 3 and sealing shroud 2 dynamic coverage air inlet 13, regulate air inlet 13 size so that corresponding change can occur the muzzle velocity of sandblasting area and medium. Specifically, when input pressure state is constant, when air inlet 13 becomes big, sandblasting area will become big, and the muzzle velocity of medium will diminish. When air inlet 13 diminishes, sandblasting area will diminish, and the muzzle velocity of medium will become big. This quality that improve sandblasting processing and efficiency, extend the use scope of nozzle, and simple in construction, easy to operate.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
