Abstract
The utility model provides a positive-pressure anti-return-air anti-return-water device and belongs to the field of equipment preventing air and water from returning when gas of a coal mine explodes and burns. The positive-pressure anti-return-air anti-return-water device comprises a cylinder shell (1), a working connecting port (5), a system connecting port (3) and a separating plate (8). The positive-pressure anti-return-air anti-return-water device is characterized in that an automatic water discharging valve (6) is arranged on the side surface of the bottom of the cylinder shell (1), and the automatic water discharging valve (6) is connected with a stainless steel floating ball (7) through a pull wire. The positive-pressure anti-return-air anti-return-water device realizes automatic discharge of condensate water under the condition of normal positive pressure.
Description
Technical field
The malleation anti feedback is prevented water recovery apparatus, anti-non-return water, anti feedback apparatus field when belonging to the blast of coal mine gas pipeline and burning, be specifically related to a kind of anti-non-return water, anti feedback during for coal mine gas pipeline blast and burning, have simultaneously the isolated plant of function of preventing back-fire.
Background technology
The anti-water recovery apparatus of FHS anti feedback belongs to gas drainage under suction and the safety device that utilize VS .NET Prerequisites jointly with the explosion-proof fireproof tempering device of FHQ, FBQ water seal explosion-protection equipment; be applicable to be installed in the gas delivery pipeline system; generally be installed in apart from user or the nearer place of gas pump, play about the protection mine, draw-off pump station and user's safety.
The anti-water recovery apparatus of traditional anti feedback all adopts the hand-actuated function, and can't realize the automatic draining function, and it should be discharged water to its equipment by the special messenger during operation, may have a strong impact on pumping of methane gas as draining is untimely, causes the accident.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide the self-draining malleation anti feedback of a kind of tank body to prevent water recovery apparatus.
The technical scheme that its technical problem that solves the utility model adopts is: this malleation anti feedback is prevented water recovery apparatus, comprise cylindrical shell, the work connector, system's connector, dividing plate, it is characterized in that: described cylindrical shell end face middle part is fixed with the safety anti-explosive skin, end face one side is established manual water supplement port, the cylindrical shell left side system connector of setting up departments, the work connector is established on the cylindrical shell right side, system's connector and work connector are all by isometrical pipeline connection inner barrel, the pipeline inner port is opening upward all, the connector pipeline inner port of wherein working is provided with dividing plate, the bottom sides of cylindrical shell is established automatic drain valve, and automatic drain valve is connected the stainless steel floating ball of hollow by draught line.
The slightly larger in diameter of described dividing plate is fixed on work connector pipeline inner port place in a side by folding in work connector pipeline inner port diameter.
Described automatic drain valve condensed water in cylindrical shell increases, and during the stainless steel floating ball floating, is opened by the draught line traction, automatically gets rid of under the effect of condensed water malleation in cylindrical shell, and automatic drain valve is by its contained spring structure autoshutdown when liquid level falls back.
The anti-water recovery apparatus of malleation anti feedback is installed between drainage system and storage facilities or the atmosphere, and system's connector 3 is connected with stocking system pipeline and ancillary service, and work connector 5 is connected with drainage system pipeline and ancillary service.
Compared with prior art, the beneficial effect that the anti-water recovery apparatus of malleation anti feedback of the present utility model has is: simple in structure, easy for installation, because the material selection stainless steel material, so corrosion resistance is strong.This product structure is simple, and is safe and reliable.In pumping the gas course of work, the cover plate in the device is opened under gas pressure, is in normal operating conditions; When carrying without methane gas, the device inner cover plate compresses the air inlet pipe mouth under the weighted lever active force, can prevent the gas loopback like this; When blasting, the device inner cover plate compresses the air inlet mouth of pipe equally simultaneously, and pressure can be washed the safety anti-explosive skin open, to reach the purpose of pressure-relief explosion-proof.

The specific embodiment
Fig. 1 ~ 4th, the most preferred embodiment of the anti-water recovery apparatus of the utility model malleation anti feedback is described further below in conjunction with 1 ~ 4 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1 ~ 4: the utility model malleation anti feedback is prevented water recovery apparatus, comprise cylindrical shell 1, work connector 5, system's connector 3, dividing plate 8, described cylindrical shell 1 end face middle part is fixed with safety anti-explosive skin 2, end face one side is established manual water supplement port 4, described cylindrical shell 1 left side set up departments the system connector 3, work connector 5 is established on cylindrical shell 1 right side, system's connector 3 and work connector 5 are all by isometrical pipeline connection cylindrical shell 1 inside, pipeline 1 inner port is opening upward all, the connector 5 pipeline inner port of wherein working are provided with dividing plate 8, the bottom sides of described cylindrical shell 1 is established automatic drain valve 6, and automatic drain valve 6 is connected the stainless steel floating ball 7 of hollow by draught line.The slightly larger in diameter of described dividing plate 8 is fixed on work connector 5 pipeline inner port places in a side by folding in work connector 5 pipeline inner port diameters.
Operating principle: when drainage system is worked, can form certain malleation at work connector 5 places; along with the pressure reduction of dividing plate 8 front and back is different; methane gas pours in and backs down dividing plate 8 from work connector 5 and finishes conveying or discharging work; in when, in storage facilities or the atmosphere burning things which may cause a fire disaster accident occuring when; dividing plate 8 plays the effect of individual event valve; make the burning things which may cause a fire disaster accident affect drainage system work along pipeline; system's connector lateral pressure was too high when accident occured; safety anti-explosive skin 2 can be because of the variation explosion of pressure; release pressure plays the effect of protection drainage system.The existence of condensate water is arranged in the normal discharge process unavoidably, and cylindrical shell 1 interior employing stainless steel floating ball 7 carries out liquid level control, and automatic drain valve 6 work discharge water and equilibrium water amount when water level transfinites.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
