Abstract
The invention relates to a galvanized steel pipe inner wall blowing head which comprises a gland, a cylinder and an air head. The head of the air head is spherical. A bolt arranged on a center shaft of the air head is coaxial with the cylinder, and the gland is fixedly mounted through a fixing nut. The gland is coaxially and fixedly mounted on the cylinder and provided with an air inlet. An air cavity is formed by a closed space formed by the gland, the cylinder and the air head. A gap is reserved between the inner edge of the end of the cylinder and the spherical outer edge of the air head. A circle of flow blocking holes are formed in the outer edge of the air head at intervals. The galvanized steel pipe inner wall blowing head adopts the mode that the gap formed by the inner edge of the circular cylinder and the outer edge of the air head serves as a blowing hole, formed air flow is in an umbrella shape, the inner wall of a galvanized steel pipe can be uniformly blown, the blowing effect is good, and the flow is consistent; and a plurality of distribution holes are uniformly formed in the cylinder in the radial direction and enable air to be more uniformly input into the air cavity, airflow turbulence caused by a vortex formed in the air cavity is prevented, and the blowing effect is improved.
Description
Technical field
The invention belongs to field of metallurgy, be related to coating steel pipe it is zinc-plated after process, a kind of especially coating steel pipe inside pipe wall
Blow head.
Background technology
Coating steel pipe after surface derusting, solvent process, needing to carry out galvanizing by dipping work step, it is zinc-plated after steel pipe in
Wall is retained substantial amounts of metallic zinc residual liquid, and the residual liquid needs to blow away using the pressure air in blow head.At present, blow head is to adopt to blow
The mode in hole, aperture blowing are distributed on the outer rim position of blow head, to realize uniformly being blown coating steel pipe inwall.This structure
Blow head in injection, to the injection of coating steel pipe inwall be not it is visibly homogeneous, and, position can form gas and return in the middle part of the blow head
Stream, the backflow produce turbulent flow to the air-flow being blown, and cause the air-flow being blown to be cross-linked with each other, thus have impact on to zinc liquid it is stable,
It is uniform to be blown.
By retrieval, the patent document of correlation is not found.
The content of the invention
It is an object of the invention in place of overcoming the deficiencies in the prior art, there is provided one kind can coating steel pipe inwall carry out surely
Fixed, uniform injection and the coating steel pipe inside pipe wall blow head of elimination backflow.
The present invention solves the scheme that adopted of its technical problem：
A kind of coating steel pipe inside pipe wall blow head, including gland, cylinder body and gas head, the head of gas head is sphere, its axis
The made bolt in position is coaxial with cylinder body, and is fixedly mounted with using clamp nut, and gland is coaxially packed on cylinder body, and gland is formed with air inlet
Mouthful, the confined space constituted by gland, cylinder body and gas head forms air cavity, between the spheroid outer rim of cylinder ends inner edge and gas head
Gap is left, the gap is gas hole；The pressure air entered from the air inlet outer rim of Jing gas holes in gas head in the air cavity
Umbrella air flow blowing is formed, is uniformly spaced with footpath in the outer rim of gas head and is formed with a circle restricted orifice.
And, in cylinder diameter to being uniformly formed with multiple tracks dispensing orifice.
And, round cup type is made in the entrance of the gas hole and restricted orifice of air intracavity.
Advantages of the present invention and good effect are：
1st, this blow head is formed by the way of the gap formed by circular cylinder body inner edge and gas head outer rim is as gas hole
Air-flow be umbrella shape, coating steel pipe inside pipe wall can be uniformly blown, injection effect it is good, flow is consistent.
2nd, this blow head is formed with a circle restricted orifice in the outer rim inboard of gas head, and the air-flow sprayed by the restricted orifice can stop and blow
The air-flow of pore, it is to avoid turbulent flow, it is ensured that the normal airflow injection of gas hole.
3rd, in cylinder diameter to multiple tracks dispensing orifice is uniformly formed with, the dispensing orifice can be such that air is input into being more uniformly distributed to this blow head
To in air chamber, it is to avoid vortex is formed in air chamber and cause the disorder of air-flow, improve the effect of injection.
4th, this blow head makes round cup type in the entrance of the gas hole and restricted orifice of air intracavity, gathers can air-flow here
Collection, improves the pressure of injection.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following examples are descriptive
, it is not determinate, it is impossible to which protection scope of the present invention is limited with this.
A kind of coating steel pipe inside pipe wall blow head, including gland 2, cylinder body 1 and gas head 7, the head of gas head is sphere, wherein
The made bolt 3 in axle portion position is coaxial with cylinder body, and is fixedly mounted with using clamp nut 4, and gland is coaxially packed on cylinder body, and gland is formed with
Air inlet 5, the confined space constituted by gland, cylinder body and gas head form air chamber 8, in cylinder ends inner edge and the spheroid of gas head
Gap 10 is left between outer rim, the gap is gas hole, the pressure air entered from air inlet Jing gas holes in the air cavity exist
The outer rim of gas head forms umbrella air flow blowing.
In cylinder diameter to multiple tracks dispensing orifice 9 is uniformly formed with, the dispensing orifice can make air be input to air with being more uniformly distributed
In chamber, it is to avoid form vortex in air chamber and cause the disorder of air-flow, it is twice shown in the present embodiment accompanying drawing.
Round cup type 11 is made in the entrance of the gas hole and restricted orifice of air intracavity, is assembled can air-flow here, be carried
The pressure of high injection.
Turbulent flow is formed in order to avoid the backflow of gas hole blast pass, is uniformly spaced with footpath in the outer rim of gas head and is formed with
One circle restricted orifice 6.
