Description
Technical field
The utility model belongs to tubing field, and in particular to be a kind of new type mining gas drainage under suction tubing.
Background technology
The natural gas that coal mine gas refers to then.Main component is alkane, and wherein methane accounts for the overwhelming majority, separately there is a small amount of second
Alkane, propane and butane, in addition, general also contain hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor and micro inert gas, such as helium
With argon etc..The bulk gas that plant generates in coalification course, also known as coal bed gas.The organic matter of rotten plant type, is bacterially decomposed, can
Generate gas；Thereafter as deposit buried depth increases, in very long geological epoch, since coal seam is subjected to high temperature, high pressure
Effect, into coal carbonization metamorphic episode, volatile matter is reduced in coal, and fixed carbon increases, and generates a large amount of gas, is stored in coal
In layer or the hole and crack of rock stratum.With the increase of pit mining depth, more and more local mines become high methane
Mine, Gas Disaster are on the rise.Gas drainage pipe used at present, since the environment of mine causes, after a period of use
It is susceptible to frosted rupture, and then leads to the phenomenon that leaks air during gas drainage under suction, causes safety accident；Due to rigidity compared with
Difference, radial crushing strength is low, under the operating condition of gas drainage system, it is made to be not easy to be inhaled flat under the conditions of high negative pressure or become
Shape；And gas drainage pipe can only fixed extraction, cannot be adjusted according to underground situation, cause unnecessary resource wave
Take, while also increasing unsafe factor.
And the prior art, Chinese patent（Application number：201420362370.5）Disclose gas drainage under suction under a kind mine
Tubing, it is main solve the problem of be prevent tube body deformed when by draught head it is flat lead to not pumping, but
It is to need to be pressurized suction when there is pumping, is come into contact in a large area because reinforcing rib can be formed gas, to increase resistance,
And smaller scope of application.
Utility model content
In order to solve the above technical problems, the utility model provides and a kind of can be adjusted whole intensity as needed
, the larger new type mining gas drainage under suction tubing of the scope of application.
To achieve the above object, the technical solution adopted in the utility model is a kind of new type mining gas drainage under suction tubing, packet
Tube body is included, tube body includes outer tube and inner tube, and structural feature is that cavity is formed between outer tube and inner tube, is equipped in cavity hollow
Sebific duct, hollow sebific duct are spirally wound on the surface of inner tube, and hollow sebific duct is several, and several hollow sebific ducts are clipped in both ends by collet
Connection, is equipped with connecting plate between the outer tube and the end of inner tube, connecting plate is equipped with the open slot coordinated with collet, opening
Gasket is equipped in slot, connecting plate is tightly connected with outer tube and inner tube, and linen thread braiding layer is equipped in the wall of the hollow sebific duct.
Collet is equipped with the through-hole coordinated with hollow sebific duct as a further improvement of the utility model, hollow sebific duct
End is bonded in through-hole.
Collet is equipped with female blind hole as a further improvement of the utility model, and collet is logical with open slot
It crosses and is bolted.
The end of hollow sebific duct is equipped with sealing-plug as a further improvement of the utility model,.
The end of tube body is detachably equipped with protection cap as a further improvement of the utility model,.
The utility model has the beneficial effects that：Reasonable design, simple in structure, radial crushing strength is high, good toughness, elasticity
Greatly, tensile strength is high, can bear larger pressure, be not easily broken, and can adjust integral strength according to actual conditions, avoid
The unnecessary wasting of resources, service life are long.
