Abstract
The utility model relates to a ring-shaped elastic washer for a mine gas pump drainage hole packer. The ring-shaped elastic washer comprises a cylindrical body, and is characterized in that a ring-shaped groove is formed on the end surface of one axial side of the body in a surrounding manner. When in use, the ring-shaped elastic washer is arranged on the outer wall of a pipe connector and embedded in a gas drainage hole, and the pipe connector is connected with a drainage pipe; due to the elasticity of the ring-shaped elastic washer, the ring-shaped elastic washer is in interference fit with the gas drainage hole for sealing; cement paste or polyurethane is then arranged outside for plugging; and when the cement paste or polyurethane enters the groove, the ring-shaped elastic washer, the gas drainage hole and the pipe connector are further expanded, so that the sealing effect is better. Therefore, the ring-shaped elastic washer adopting the technical scheme has the effects of simple structure, low manufacturing cost, convenience in use, low possibility of water or gas pipeline spalling, as well as better hole packing effect.
Description
Technical field
The utility model relates to damp pump drainage apparatus field, is specifically related to a kind of damp pump drainage hole packer annular resilient packing ring.
Background technique
Traditional drawing out methane is that a releasing pipe is inserted in the gas extraction hole, then cement slurry or polyurethane advanced to carry out shutoff, pump drainage in the hole with shutoff equipment pressure injection.This method is not only time-consuming, effort but also cost height, efficient are low; Other modes also have water pressing or pneumatic-typed gas hole packer, these two kinds of device fabrication cost height, use inconvenient, also easy spalling water, air pipe, sealing of hole weak effect.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, easy to use, is difficult for spalling water, air pipe, the damp pump drainage hole packer annular resilient packing ring of sealing of hole better effects if.
For achieving the above object, the utility model provides following technological scheme: a kind of damp pump drainage hole packer annular resilient packing ring, comprise the body that is cylindric setting, it is characterized in that: an axial side end face of described body is provided with the annular recess around this end face.
By adopting technique scheme, during use, the annular resilient packing ring is arranged on the pipe connector outer wall, the annular resilient packing ring embeds in the gas extraction hole, pipe connector is connected with releasing pipe, because the elastic reaction of annular resilient packing ring, make annular resilient packing ring and gas extraction hole interference fit reach the purpose of sealing, and then externally carry out further shutoff with cement slurry or polyurethane, cement slurry or polyurethane enter in the groove, further make annular resilient packing ring and gas extraction hole and pipe connector swelling mutually, thereby sealing effect is better.Therefore, technical solutions of the utility model have simple in structure, low cost of manufacture, easy to use, are difficult for spalling water, air pipe, the effect of sealing of hole better effects if.
The utility model also further is set to: described annular recess comprise with the pipe connector central shaft to the madial wall that parallels setting, and the outer side wall that is connected with madial wall and is provided with, described madial wall and outer side wall angle are the acute angle setting.
By adopting technique scheme, further strengthen ring-type elastic washer and gas extraction hole and pipe connector swelling effect mutually, thereby sealing effect is better.
The utility model also further is set to: described madial wall and outer side wall angle be more than or equal to 50 °, and be less than or equal to 65 ° of settings.
By adopting technique scheme, further strengthen ring-type elastic washer and gas extraction hole and pipe connector swelling effect mutually again, thereby sealing effect is better.
The utility model also further is set to: the corresponding annular recess one end periphery of described body is provided with the flange to outer lug.
By adopting technique scheme, flange can compress mutually with the gas extraction hole aperture, further strengthens the sealing effect between ring-type elastic washer and the gas extraction hole.
The utility model also further is set to: described body relative annular recess the other end end face and periphery wall are by the transition of external convex arc shape chamfering.
By adopting technique scheme, make the annular resilient packing ring be more prone to embed in the gas extraction hole, thereby use convenient.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model damp pump drainage hole packer annular resilient packing ring example structure figure;
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the disclosed damp pump drainage of the utility model hole packer annular resilient packing ring comprises the body 1 that is cylindric setting, and an axial side end face of described body 1 is provided with the annular recess 11 around this end face.By adopting technique scheme, during use, the annular resilient packing ring is arranged on the pipe connector outer wall, the annular resilient packing ring embeds in the gas extraction hole, pipe connector is connected with releasing pipe, because the elastic reaction of annular resilient packing ring, make annular resilient packing ring and gas extraction hole interference fit reach the purpose of sealing, and then externally carry out further shutoff with cement slurry or polyurethane, cement slurry or polyurethane enter in the groove 11, further make annular resilient packing ring and gas extraction hole and pipe connector swelling mutually, thereby sealing effect is better.Therefore, technical solutions of the utility model have simple in structure, low cost of manufacture, easy to use, are difficult for spalling water, air pipe, the effect of sealing of hole better effects if.
The utility model annular recess 11 can be with various different modes settings, as rectangle or triangle etc., present embodiment is preferred, described annular recess 11 comprise with the pipe connector central shaft to the madial wall 111 that parallels setting, and the outer side wall 112 that is connected and is provided with madial wall, described madial wall 111 is the acute angle setting with outer side wall 112 angle α.By adopting technique scheme, further strengthen ring-type elastic washer and gas extraction hole and pipe connector swelling effect mutually, thereby sealing effect is better.Present embodiment madial wall 111 preferably is set to outer side wall 112 angle α, more than or equal to 50 °, and is less than or equal to 65 ° of settings.By adopting technique scheme, further strengthen ring-type elastic washer and gas extraction hole and pipe connector swelling effect mutually again, thereby sealing effect is better.
Present embodiment also further is set to: described body 1 corresponding annular recess 11 1 end peripheries are provided with the flange 12 to outer lug.By adopting technique scheme, flange 12 can compress mutually with the gas extraction hole aperture, further strengthens the sealing effect between ring-type elastic washer and the gas extraction hole.
This real embodiment also further is set to: described body 1 relative annular recess 11 the other end end faces and periphery wall are by 13 transition of external convex arc shape chamfering.By adopting technique scheme, make the annular resilient packing ring be more prone to embed in the gas extraction hole, thereby use convenient.
