Abstract
The under well gas extraction spiral pipe device of the utility model comprises a pipe body 4 and a flange 1. The pipe body is made from a galvanized steel strip or at least a single-head galvanized steel strip whose one side is clutched spirally and connected circularly with the corresponding side. The flange is radially riveted with the pipe body through a flame-proof fluid sealant. Compared with the current steel welded pipe and the glass steel pipe, the utility model is provided with airtight structure. Air escape, tarnish and static electricity can not occur in operation. The utility model has no hidden danger and is provided with ethereal weight, so that the under well gas extraction spiral pipe is convenient to convey and operate. The difficulty of the operation is reduced effectively.
Description
Technical field
The utility model relates to a kind of fire damp extraction airduct, refers to a kind of fire damp extraction volute especially.
Background technique
The used airduct of coal mine gas extraction is selected steel welded tube or Glass Steel Tube usually for use.They have the following disadvantages in production and using process:
1, the steel welded tube is in course of working, and is air tight for guaranteeing weld seam, the welded tube welding quality required very high, strengthens the production difficulty of production link; The steel welded tube is easy to corrosion in the wet environment of down-hole, this not only can shorten its working life, and the pit that is produced can cause the pipeline gas leakage, and downhole safety is threatened; Steel welded tube thickness of pipe wall, relatively heavier, producing, carrying, constructing all can acquire a certain degree of difficulty, and cost is higher.
2, Glass Steel Tube toxicity in production link is bigger, and environment and producers are had direct harm; When Glass Steel Tube toughness and intensity were big, antistatic poor, antistatic when high, strength and toughness was poor, and fracture or crack take place in carrying, construction easily; Glass Steel Tube easily produces static, when the antistatic treatment quality goes wrong, can threaten to downhole safety.
The model utility content
It is a kind of in light weight that the purpose of this utility model will provide exactly, airtight air tight, the fire damp extraction volute that is difficult for corrosion, do not have static, have higher-strength and toughness of structure.
For achieving the above object: the utility model adopts following technological scheme: fire damp extraction volute, constitute by body and flange plate, and flange plate cooperates connection with body.Body is formed to enclose to connect with its corresponding sides spiral interlock on one side by Galvanized Steel Strip.Flange plate connects with body by flame retardant sealant.Body is enclosed to connect with the interlock of corresponding sides spiral on one side by the single head Galvanized Steel Strip at least and forms.The interlock of Galvanized Steel Strip spiral is enclosed and is connect the convex tendon that is produced and all protrude to the body external diameter.Flange plate is radially by flame retardant sealant and body riveted joint.
Form socket through the spiral interlock after steel strip surface is zinc-plated, have higher intensity and rust resistance; It can not produce static, can not produce threat to downhole safety; Its structure is airtight, gas leak phenomenon can not take place, and does not have potential safety hazard; It is in light weight, and it is more convenient to carry, construct, and effectively reduces difficulty of construction.

Mark
1 flange plate, 2 convex tendons, 3 flame retardant sealants, 4 bodys
5 Galvanized Steel Strips 6 are 7 corresponding sides on one side
Embodiment
With reference to Fig. 1.This is that the single head Galvanized Steel Strip forms structure airtight body 4 to enclose to connect with its corresponding sides spiral interlock on one side, and the convex tendon 2 that is produced all protrudes to the body external diameter, and the internal diameter of tube body cylndrical surface keeps smoothly being beneficial to ventilation, the wear resistance of reinforced pipe body diameter like this.Flange plate 1 is by flame retardant sealant and body radial rivet, improves the seal that connects between flange plate and the body.
With reference to Fig. 2.This is the one side 6 of Galvanized Steel Strip 5 and the interlock mode of corresponding sides 7.
With reference to Fig. 3.This is that the double end Galvanized Steel Strip surrounds the airtight body of structure 4 by the mutual spiral interlock in both sides.Flange plate 1 is identical with embodiment 1 with the position of body connecting mode and flame retardant sealant.
Claims (4)
1, a kind of fire damp extraction volute is made of body (4) and flange plate (1), and flange plate cooperates connection with body, it is characterized in that: body is formed to enclose to connect with the interlock of corresponding sides spiral on one side by Galvanized Steel Strip; Flange plate connects with body by flame retardant sealant (3).
2, fire damp extraction volute according to claim 1 is characterized in that: body is enclosed to connect with the interlock of corresponding sides spiral on one side by the single head Galvanized Steel Strip at least and forms.
3, fire damp extraction volute according to claim 1 is characterized in that: the interlock of Galvanized Steel Strip spiral is enclosed and is connect the convex tendon (2) that is produced and all protrude to the body external diameter.
4, fire damp extraction volute according to claim 1 is characterized in that: flange plate is radially by flame retardant sealant (3) and body riveted joint.
