Description

A kind of well head retracting device of coal bed gas
Technical field
The utility model relates to a kind of retracting device, refers more particularly to a kind of well head retracting device of coal bed gas.
Background technology
At present.When coal mining is produced, need to carry out pump drainage work to water in coalfield and coal bed gas (gas) in advance, by wellhead casing pipe centralized collection major part coal bed gas, remaining coal bed gas is discharged mainly through water-pumping/draining mixing, but only rely on simple water-pumping/draining that the pump drainage efficiency of coal bed gas can be made low, the coal bed gas of nearly 5%-20% slatterns, secondly, the methane isothermal chamber gas of discharge can impact environment, has certain potential safety hazard.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the well head retracting device of safe and reliable coal bed gas.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises multiple recycling can, described recycling can is provided with coal bed gas import and coal bed gas collection outlet, pneumatic actuator, Pneumatic valve, work keg float and safe ball float is provided with in described recycling can, the ball face sealing device of described pneumatic actuator is arranged on the floss hole of described recycling can, described pneumatic actuator is provided with work keg float, described safe ball float is connected with the trigger input of described Pneumatic valve, and the control output end of described Pneumatic valve is connected with the control input end of described pneumatic actuator.
Particularly, multiple described recycling can is for being connected in series or being connected in parallel.
Further, the base of described recycling can is provided with bearing.
Particularly, described recycling can is provided with safety valve.
Further, described coal bed gas is collected in outlet and is provided with one way valve.
Particularly, described floss hole is arranged on the bottom of described recycling can.
The beneficial effects of the utility model are:
The utility model gets rid of unnecessary waste water and matchmaker's powder by arranging pneumatic actuator with work keg float interlock effect, and safe ball float and Pneumatic valve can improve the safety that equipment runs simultaneously, and structure is simple, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Shown in figure: 1-recycling can, 2-coal bed gas collects outlet, 3-one way valve, 4-pneumatic actuator, the safe ball float of 5-, 6-safety valve, 7-Pneumatic valve, 8-ball face sealing device, 9-floss hole, and 10-works keg float, the import of 11-coal bed gas.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises multiple recycling can 1, recycling can 1 is provided with coal bed gas import 2 and coal bed gas collection outlet 11, pneumatic actuator 4, Pneumatic valve 7, work keg float 10 and safe ball float 5 is provided with in recycling can 1, the ball face sealing device 8 of pneumatic actuator 4 is arranged on the floss hole 9 of recycling can 1, pneumatic actuator 4 is provided with work keg float 10, safe ball float 5 is connected with the trigger input of Pneumatic valve 7, and the control output end of Pneumatic valve 7 is connected with the control input end of pneumatic actuator 4.
Multiple recycling can 1 is for being connected in series or being connected in parallel, two device tandem working can ensure system reliability service, be convenient to timely Inspection and maintenance, the base of recycling can 1 is provided with bearing, handled easily, recycling can 1 is provided with safety valve, when pressure reduction is excessive time, can partial pressure in removal recycling can 1 in time, avoid because blast causes more major injury.
Coal bed gas is collected in outlet 2 and is provided with one way valve 3, and prevent gas backwash, floss hole 9 is arranged on the bottom of described recycling can 1.
Workflow of the present utility model is as follows:
When the water in water in coalfield and coal bed gas, coal bed gas and coal dust enter recycling can 1 from coal bed gas import 2, the keg float 10 that works under a certain pressure drives the ball face sealing device 8 on pneumatic actuator 4 upwards to lift, waste water and matchmaker's powder is emitted by floss hole 9, when pressure is larger due to differential pressure action or other reasons work keg float 10 can not lift ball face sealing device 8 time, water level rises the action of safe ball float 5, and Pneumatic valve 7 detects that controlling pneumatic actuator after safe ball float 5 arrives upper limit water level forces lifting ball face sealing device 8 to discharge waste water and matchmaker's powder.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
