Abstract

The utility model provides a flange connecting mechanism of helical corrugated pipes. The flange connecting mechanism comprises flanges, a rubber sealing ring, a first bolt helical corrugated pipe and a second bolt helical corrugated pipe, wherein the two ends of the first and second bolt helical corrugated pipes are provided with the flanges, and thread openings are uniformly distributed on the flanges; and one rubber sealing ring is arranged between the flange at one end of the first bolt helical corrugated pipe and the flange at one end of the second bolt helical corrugated pipe and passes through the two flanges through bolts to be fixed with the flanges together. The flange connecting mechanism disclosed by the utility model has the beneficial effects that by adopting the technical scheme, the connecting mechanism is made of PE (Poly Ethylene) plastic with antistatic and flame-retarding functions, and the connecting manner has the advantages of long service life, high anti-impact performance, corrosion resistance, no pollution and high performance; in a construction process, the connecting manner only needs simple mechanical connection and does not need open fire, so that the flange connecting mechanism can be safely used under a coal mine; and the connecting manner has a short working period, installation personnel do not need to be trained, special equipment support is not needed, and the connecting mechanism has the advantages of high timeliness and the like.

Description

A kind of flange bindiny mechanism of helical bellows
Technical field
The utility model belongs to flange interconnection technique field, especially relates to a kind of flange bindiny mechanism of helical bellows.
Background technique
In existing technology, the application of coal mine gas extraction tubing is mainly take steel pipe and Glass Steel Tube as main, but steel pipe exists perishable, and the surface needs brushing corrosion resistant coating, collision to play easily spark, the shortcoming that Security is low, the life-span is short, and the Glass Steel Tube impact resistance is low, damages easily in the using process, easily breaks, and antistatic composition is coated in tube surfaces, and skewness, in use, lose easily the antistatic composition on surface.
Summary of the invention
Problem to be solved in the utility model provides a kind of flange bindiny mechanism of helical bellows, especially is fit to the application of coal mine gas extraction tubing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flange bindiny mechanism of helical bellows, comprise flange, rubber seal, the first and second bolt helical bellowses, described the first and second helical bellows two ends are equipped with flange, are evenly distributed with screw mouth on the described flange; Being provided with a rubber seal in the middle of the flange of the flange of described the first helical bellows one end and described the second helical bellows one end passes two flanges by bolt again and is fixed together.
Described flange is to have PE plastics antistatic, anti-flaming function.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the material that this bindiny mechanism uses be have antistatic, the PE plastics of anti-flaming function, this Placement long service life, shock resistance is high, and is corrosion-resistant pollution-free, and performance is high; This Placement is simple mechanical connection in work progress, and the flames of anger can be used under coal mine safely; This Placement duration is short, need not installation personnel is giveed training, and need not special equipment support, ageing height; More convenient to operate; Have simple in structure, easy to maintenance, the advantage such as processing cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is coupled condition schematic representation of the present utility model.
Among the figure:
1, flange 2, rubber seal 3, bolt
4, the second helical bellows 5, the first helical bellows
Embodiment
As illustrated in fig. 1 and 2, the flange bindiny mechanism of a kind of helical bellows of the utility model, comprise flange 1, rubber seal 2, the first helical bellows 5 and the second helical bellows 4, described the first helical bellows 5 and the second helical bellows 4 two ends are equipped with flange 1, are evenly distributed with screw mouth on the described flange 1; Being provided with a rubber seal 2 in the middle of the flange 1 of described the first helical bellows 5 one ends and the flange of described the second helical bellows 4 one ends 1 passes two flanges 1 by bolt 3 again and is fixed together.Further, described flange 1 is for having PE plastics antistatic, anti-flaming function.
Flange 1 is through molding and forming, is connected to above the helical bellows.
The working procedure of this example: the flange 1 on two helical bellowses is docked, and the centre accompanies rubber seal 2, passes screw mouth with bolt 3 and connects and get final product.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
