Description

One kind being used for ampuliform inner cavity of component blast mouth

Technical field

It is specifically a kind of to be used for ampuliform inner cavity of component blast mouth the utility model relates to blast mouth technical field.

Background technique

Blast nozzle for ampuliform inner cavity of component blast welds a pipe, pipe aperture usually using blast pipe fixing head After protrude into and carry out blast in bottle, after a period of use, welding position is just broken quickly.

Such as the lance head and Chinese patent of the suction-type inner hole sand-blasting gun that China Patent No. is CN201320748729.8 Application No. is the sand-aerating apparatus in a kind of blast nozzle of structure simple economy of CN201410714853.1 not to be suitable for ampuliform zero Part inner cavity blast, it is also difficult to solve inner cavity blast mouth welding breaking solution.

Summary of the invention

To solve the above-mentioned problems, the utility model proposes one kind to be used for ampuliform inner cavity of component blast mouth.

One kind being used for ampuliform inner cavity of component blast mouth, including pipe fitting, the blast mouth pipe and blocking cap that connect with pipe fitting, institute The pipe fitting stated is all made of with blast mouth pipe and blocking cap and is threadedly coupled, and is provided with guidance air-flow at the internal diameter of pipe joint transformation The chamfering moved to blast mouth pipe.

Sand grains ejection position designs at 15mm of the blast mouth pipe far from pipe fitting end face.

The end face of the blast mouth pipe is sealed using blocking cap.

The length of the blast mouth pipe is arranged in 100mm between 400mm.

The pipe fitting both ends all have opening, in-profile and the ampuliform part of the cross section of the pipe fitting Exterior contour fitting.

The beneficial effects of the utility model are: the utility model is connected through a screw thread so that pipe fitting, blast mouth pipe and stifled Cap three is arranged to three-stage, and maintenance easy to disassemble, when solving ampuliform part blast, blast mouth pipe rapid wear destroys and is difficult to repair Multiple problem；It is worked by the way that guidance air-flow is arranged at internal diameter of pipe joint transformation to the R5 chamfering of movement at blast mouth pipe convenient for blast Progress, improve service life, be easily changed, safeguard and use.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the pipe joint structure schematic diagram of the utility model；

Fig. 2 is the A-A schematic cross-sectional view of Fig. 1 of the utility model；

Fig. 3 is the blast mouth pipe structural schematic diagram of the utility model；

Fig. 4 is the blocking cap structural schematic diagram of the utility model.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under It is further described in face of the utility model.

As shown in Figures 1 to 4, a kind of to be used for ampuliform inner cavity of component blast mouth, including pipe fitting 1, connect with pipe fitting 1 Blast mouth pipe 2 and blocking cap 3, the pipe fitting 1 is all made of and is threadedly coupled with blast mouth pipe 2 and blocking cap 3, the pipe fitting Chamfering of the guidance air-flow to movement at blast mouth pipe 2 is provided at 1 internal diameter transformation.

The chamfering is R5.

Using blast mouth pipe 2 carry out ampuliform part blast during, the blocking cap 3 being lost at first, using it is preceding will be at blocking cap 3 It is dismantled, if loss is larger, blocking cap 3 can be replaced；After a period of use, 2 wall of blast mouth pipe is impaired is thinned, out After existing leakage sand situation, independently blast mouth pipe 2 can be replaced；Pipe fitting partition losses, can also individually more to after to a certain degree It changes.

Sand grains ejection position designs at 2 15mm far from 1 end face of pipe fitting of blast mouth pipe.

The end face of the blast mouth pipe 2 is sealed using blocking cap 3.

The utility model is connected through a screw thread so that pipe fitting 1, blast mouth pipe 2 and 3 three of blocking cap are arranged to three-stage, just It is safeguarded in dismounting, when solving ampuliform part blast, blast mouth pipe rapid wear destroys and is difficult to the problem of repairing.

It is convenient for blast work to the R5 chamfering of movement at blast mouth pipe 2 by the way that guidance air-flow is arranged at 1 internal diameter transformation of pipe fitting The progress of work, improves service life, is easily changed, safeguards and uses.

The length of the blast mouth pipe 2 is arranged in 100mm between 400mm.

The length of the blast mouth pipe 2 can be replaced according to the length of ampuliform part.

1 both ends of pipe fitting all have opening, the in-profile and ampuliform part of the cross section of the pipe fitting 1 Exterior contour fitting.

The application method of the utility model are as follows: during carrying out ampuliform part blast using blast mouth pipe 2, be lost at first Blocking cap 3, will be dismantled at blocking cap 3 using preceding, if loss is larger, blocking cap 3 can be replaced；Use a period of time Afterwards, 2 wall of blast mouth pipe is impaired is thinned, and after there is leakage sand situation, can independently replace to blast mouth pipe 2；Pipe fitting part damage Consumption can also be individually replaced to after to a certain degree.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model also has Various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The requires of the utility model Protection scope is defined by the appending claims and its equivalent thereof.
