Description

Blow gun in hot-galvanize that can fix a position

Technical Field

The utility model relates to a blowing nozzle in hot-galvanize that can fix a position belongs to interior blowing device field.

Background

The interior blowing need be carried out after the pipe fitting hot-galvanize, it is generally alright to blow in the bellmouth to the pipe fitting below four cun, however often appear in the actual production process as the pipe fitting shown in figure 2 and the problem of staggering that the bellmouth leads to because of not leading well, do it to do the reason, the mouth of pipe is mainly in order to guarantee the interior blowing quality, the interior passageway of blowing in of the interior blowing mouth of design is less than the internal diameter of steel pipe slightly, because the steel pipe diameter is on the small side, the bellmouth is bigger on the large side, lead to the steel pipe not form the direction with interior blowing mouth bellmouth, consequently, the problem that the bellmouth staggers not good location with.

In view of the problems existing in the prior art, the utility model discloses combine many years' design and experience in use of relevant field, assisted by too strong professional knowledge, the design has made a hot-galvanize of can fixing a position and has gone into blow gun, overcomes above-mentioned defect.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a pair of blow gun in hot-galvanize that can fix a position can guarantee the location of pipe fitting, further improves interior blowing quality.

In order to realize the purpose, the utility model discloses a technical scheme as follows: a positionable hot galvanizing inner blow nozzle comprises an inner blow nozzle body, wherein the inner blow nozzle body is sequentially provided with a gas collection channel, a advection channel and a bell mouth channel along the gas blowing direction;

the diameter of the gas collection channel is gradually reduced along the gas blowing direction, the diameter of the horn mouth channel is gradually increased along the gas blowing direction, the advection channel is provided with a boss extending out of the bottom of the horn mouth channel, and the boss is arranged into a guide frustum.

As a preferred technical scheme, the outer wall of the gas collection channel is provided with external threads.

The utility model discloses an useful part is:

1. when the steel pipe of the utility model extends into the inner blowing nozzle body, the accurate positioning of the pipe fitting is ensured and the inner blowing quality is improved through the positioning and guiding of the conical inclined plane (positioning the outer wall of the steel pipe) of the horn mouth and the guiding frustum structure (positioning the inner wall of the steel pipe) of the boss;

2. the utility model discloses utilize behind the air current that gas collection passageway compressed air source passed through advection passageway blowout, it has improved the air pressure who erupts, has further improved interior blowing effect.

FIG. 1 is a schematic structural view of a positionable hot galvanizing inner blowing nozzle;

FIG. 2 is a schematic view of an embodiment of a traditional hot galvanizing inner blowing nozzle.

In the figure, 1, a gas collecting channel, 2, a advection channel, 3, a guide frustum, 4, a bell mouth channel, 5 and external threads.

Detailed Description

The present invention is further described below to facilitate understanding by those skilled in the art.

As shown in fig. 1, a positionable hot galvanizing inner blowing nozzle comprises an inner blowing nozzle body, wherein the inner blowing nozzle body is sequentially provided with a gas collecting channel 1, an advection channel 2 and a bell mouth channel 4 along a gas blowing direction, and the outer wall of the gas collecting channel 1 is provided with an external thread 5;

the diameter of the gas collecting channel 1 of the utility model is gradually reduced along the gas blowing direction, the gas flow transmitted from the gas source can be compressed and sprayed out through the advection channel 2, and the pressure of the sprayed gas flow is improved; the 4 diameters of horn mouth passageway become gradually along gas blowing direction, the utility model discloses advection passageway 2 is equipped with the boss and stretches out horn mouth passageway 4 bottom, and the boss establishes to direction frustum 3, and the steel pipe passes through the toper inclined plane of horn mouth (to steel pipe outer wall location) and the direction frustum 3 structure of boss (to steel pipe inner wall location) location direction when stretching into in the blow gun body, has guaranteed that the pipe fitting can pinpoint, has improved interior blowing quality, is different from the dislocation problem that traditional interior blow gun structure arouses.

For those skilled in the art, based on the teachings of the present invention, changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.

Claims (2)

1. The utility model provides a blowing nozzle in hot galvanizing that can fix a position which characterized in that: the inner blowing nozzle comprises an inner blowing nozzle body, wherein the inner blowing nozzle body is sequentially provided with a gas collecting channel, an advection channel and a bell mouth channel along the gas blowing direction;

the diameter of the gas collection channel is gradually reduced along the gas blowing direction, the diameter of the horn mouth channel is gradually increased along the gas blowing direction, the advection channel is provided with a boss extending out of the bottom of the horn mouth channel, and the boss is arranged into a guide frustum.
