Description
Technical field
The utility model relates to a kind of coal mine gas drainage pipe road automatic bleeder, particularly occurs being become in the situation of malleation by negative pressure when pipeline, when can guarantee automatic draining and do not make Gas outside pipeline, guarantees the Environmental security of tunnel or drill site.
Background technology
Gas is one of major hidden danger in Coal mine excavation, in order to solve the coal mine gas problem, utilizing vacuum pump that the gas in coal seam or goaf is extracted out is general method, when drawing out methane, due to the water in coal seam or stratum under the effect of negative pressure, flow in extraction pipeline along the drilling and sealing pipe, cause pipe resistance to increase or stop up, affect the gas drainage under suction effect.Ways of addressing this issue is at pipeline low-lying place installation negative pressure automatic drainage device or U-shaped tubular type automatic bleeder at present; but (other effect due to factors such as strata pressure and gas pressures when gas suction pump stops or overhauling; boring can produce Gas often), cause making gas drainage pipeline and main pipe in drill site to form barotropic state within the regular hour.Existing negative pressure automatic drainage device can only solve the automatic draining of negative pressure line, and when malleation appearred in pipeline, breather valve or discharging valve that the device in Gas in pipeline is known from experience by tailrace were discharged in the tunnel; And U-shaped tubular type boring tailrace can make the water in the U-shaped pipe be forced out when pipeline forms malleation, causes gas leakage.
Said method and device exist gas leakage or the space outside pipeline of gushing out, and cause local gas to gather, and have a strong impact on Safety of Coal Mine Production.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing apparatus technology, a kind of safe and reliable automatic water drainage device is provided, make it no matter pipeline is in the automatic draining that can realize gas drainage pipeline under negative pressure or positive pressure, and guaranteeing that at work pipeline and space outerpace completely cut off, assurance gas does not leak into the space beyond pipeline.
The purpose of this utility model is achieved through the following technical solutions: a kind of gas drainage pipeline automatic water drainage device, comprise Water collecting tube, cursory, guide peg, water intaking valve group, discharging valve group, breather valve, pressure-equalizing pipe, pallet component and permanent magnet, it is characterized in that: cover the installation breather valve on Water collecting tube, be provided with breather check valve and micro-pressure-difference diaphragm in described breather valve; Described discharging valve group is positioned at bottom Water collecting tube, the discharging valve group is made of discharging valve pipe, discharge water valve plate and the one way valve that discharges water, be equipped with in the discharging valve pipe valve plate that discharges water is installed outside the one way valve that discharges water, discharging valve pipe, the one way valve that discharges water is connected with the centre pilot bar respectively with pallet component.
The beneficial effects of the utility model: the utility model adopts said structure, by using discharging valve group and micro-pressure-difference formula and the knockdown breather valve structure of one way valve of two unidirectional principles, make no matter tailrace is in malleation or under negative pressure state, can work.When pipeline is the barotropic state automatic draining, guarantee tailrace catchment and the process that discharges water in communicate with extraction pipeline, isolated with outside atmosphere, make the gas in pipeline can not flow into space outerpace; When pipeline was the negative pressure state automatic draining, when guaranteeing to catchment, tailrace only communicated with pipeline, only communicates with outside atmosphere when discharging water, and prevented that extraneous gas from flowing into extraction pipeline.The utility model guarantees the gas drainage system safe and reliable operation applicable to each position of gas drainage system pipeline.

The specific embodiment
describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing, a kind of gas drainage pipeline automatic water drainage device, as shown in Figure 1, a side at Water collecting tube 15 is provided with the water intaking valve group that is made of water intaking valve pipe 11 and water inlet valve plate 10, 2 cover breather valve 1 and 1 pressure-equalizing pipe 2 are installed above Water collecting tube 15, be provided with micro-pressure-difference diaphragm 3 and breather check valve 4 in breather valve 1, be provided with cursory 6 in Water collecting tube 15, pallet component 7, centre pilot bar 8, side guide peg 5, pallet component 7 is connected with centre pilot bar 8 and side guide peg 5 respectively, guide peg 5 is connected with breather valve 1, place permanent magnet 9 on pallet component 7, centre bottom at Water collecting tube 15 is provided with the discharging valve group, the discharging valve group is by discharging valve pipe 13, valve plate 12 and one way valve 14 formations that discharge water discharge water, the one way valve 14 that discharges water is connected with centre pilot bar 8.
Operating principle of the present utility model: during use, pressure-equalizing pipe 2 is connected with the extraction pipeline of gas drainage system with water intaking valve pipe 11, the water in pipeline is in the water intaking valve pipe flow into Water collecting tube 15, and the pressure in Water collecting tube 15 is identical with the pressure in pipeline.When pipeline is the barotropic state automatic draining, guarantee tailrace catchment and the process that discharges water in communicate with extraction pipeline, isolated with outside atmosphere, make the gas in pipeline can not flow into space outerpace; When pipeline was the negative pressure state automatic draining, when guaranteeing to catchment, tailrace only communicated with pipeline, only communicates with outside atmosphere when discharging water, and prevented that extraneous gas from flowing into extraction pipeline.
pipeline is negative pressure state: when catchmenting, breather valve 1 and discharging valve pipe 13 are in closed condition, pressure-equalizing pipe 2 is opened, make tailrace with outside isolated, the pressure in tailrace is identical with pipeline, and catchmenting in extraction pipeline opened under Action of Gravity Field into water valve plate 10, continuous inflow along with water, cursory 6 rise along centre pilot bar 8, and when reaching pallet component, cursory drive pallet component rises, and makes permanent magnet 9 progress into the adhesive distance, when discharging water, open breather check valve 4 and the one way valve 14 that discharges water in the time of permanent magnet 9 adhesive, while closing presure balance pipe 2, water inlet valve plate 10 is closed water intaking valve pipe 11 under the effect of pipeline negative pressure, cause tailrace and pipeline isolated, be communicated with outside by breather valve 1 simultaneously, water in Water collecting tube 15 is under the effect of deadweight at this moment, open the valve plate 12 that discharges water, by discharging valve pipe 13, water is flowed out, along with continuously outflowing of water, cursory 6 descend along centre pilot bar 8, after reaching certain position, drive pallet component 7 assemblies pull open permanent magnet 9, tailrace is returned to catchment (at first) state.In the process of discharging water, along with the water in Water collecting tube 15 flows out, in cylinder, with the extraneous micro-pressure-difference that produces, micro-pressure-difference diaphragm 3 is opened, and outside gas enters in Water collecting tube 15 by breather check valve 4, makes water in cylinder smoothly outside expelling tube.
