Abstract
The invention discloses an integrated bypass 2-position and 5-way negative pressure water drain valve. The water drain valve comprises a valve body, wherein a valve cavity is formed in the valve body, four valve cores are arranged in the valve cavity, a valve rod is fixedly arranged on the valve cores, a drilled inlet channel and a pumping outlet channel which are identical in hole diameter are formed on one side of the valve body, a drilled outlet channel and a pumping inlet channel which are identical in hole diameter are symmetrically formed on the other side of the valve body, a gas supply channel with a small hole diameter is formed between two channels, a channel which has the same hole diameter as the gas supply channel and is communicated with the pumping inlet channel is arranged on the valve cores, and the valve rod is operated to be in a pumping position or a water drain position; when the valve rod is in the pumping position, the pumping outlet and pumping inlet channels are communicated, the drilled inlet and drilled outlet channels are communicated, the gas supply and pumping inlet channels are not communicated, and the pumping outlet and drilled inlet channels are not communicated; when the valve rod is in the water drain position, the pumping outlet and pumping inlet channels are not communicated, the drilled inlet and drilled outlet channels are not communicated, the pumping outlet and drilled inlet channels are communicated, and the gas supply and pumping inlet channels are communicated. Site operation is facilitated, and the pump-extraction efficiency is increased.
Description
Technical field
The invention belongs to the connection hole pipe fitting in underground gas extraction, relate to a kind of integrated bypass two-position five-way negative pressure discharging valve.
Background technique
In coal mine gas extraction process, the ponding in tailrace, need be discharged in tailrace when the water yield in tailrace acquires a certain degree by negative pressure pump drainage by the ponding in boring.During each hand-actuated, all need the valve closing by pipeline side and boring side, open distributing valve, discharging valve simultaneously and just to discharge water normally operation.The valve quantity that this operation worker need operate is many, and workload is large; Meanwhile, the valve closing of pipeline side and boring side, mash gas pumping drilling can not realize continuous gas pumping between blowoff period, and these situations all cause the current work of discharging water to have a strong impact on the efficiency of whole gas drainage system.
So, in order to ensure the continuous extraction of gas when discharging water, increasing work efficiency, being necessary to improve existing mash gas pumping drilling jettison gear.
Summary of the invention
In order to solve the continuous extraction that can not realize the process of discharging water that prior art exists, and the problem of complicated operation, and provide a kind of integrated bypass two-position five-way negative pressure discharging valve.
The present invention is achieved by the following technical solutions:
A kind of integrated bypass two-position five-way negative pressure discharging valve,
A kind of integrated bypass two-position five-way negative pressure discharging valve, comprises the valve body that inside offers valve pocket, is provided with 4 spools in valve pocket
,spool is fixed with the valve rod controlling its rotation angle, valve body side offers the identical boring inlet passage in aperture, extraction outlet passage, opposite side symmetry offers the boring outlet passage of same apertures, extraction inlet passage, the gas distribution channels of small aperture is offered between two passages, described spool offers identical with gas distribution channels aperture and the passage communicated with extraction inlet passage, operating valve lever drives valve core rotation to enter extraction position and the position that discharges water, during described extraction position, extraction outlet passage and extraction inlet passage UNICOM, boring inlet passage and boring outlet passage UNICOM, gas distribution channels and extraction inlet passage not UNICOM, extraction outlet passage and boring inlet passage not UNICOM, described when to discharge water, extraction outlet passage and extraction inlet passage not UNICOM, boring inlet passage and boring outlet passage not UNICOM, extraction outlet passage and boring inlet passage UNICOM, gas distribution channels and extraction inlet passage UNICOM.
The present invention adopts integrated valve, arranges corresponding path and closed-circuit system in valve inside, realizes discharging water in process, and drilling gas extraction work does not stop.Working principle is: valve working state has two, and one is normal extraction position, and two is the positions that discharge water; Five-way is the two logical and distributions that two of connection tailrace leads to, connects extraction arm, extraction boring.During extraction position, drilled tunnel and drilled tunnel UNICOM, extraction passage and extraction passage UNICOM, gas distribution channels and drilled tunnel not UNICOM, drilled tunnel and extraction passage not UNICOM, described when to discharge water, drilled tunnel and boring discharge water passage not UNICOM, extraction passage and extraction passage not UNICOM, drilled tunnel and extraction passage UNICOM, gas distribution channels and drilled tunnel UNICOM.
The valve that the present invention be directed to current tailrace is many, do not have bypass, the novel valve that execute-in-place is complicated and design, relative to existing valve, add drilled tunnel and extraction passage two-way bypass, solving gas in the on-the-spot process that discharges water can not the problem of extraction, adds gas distribution channels road and drilled tunnel, solve distribution automation issues, simplify valve quantity and be reduced to 1 by original 5, valve is become one, be reduced to one two.
The present invention reduces the setting of gas distribution valve, facilitate execute-in-place; Achieve the continuous extraction in the process of discharging water, improve gas pumping efficiency, effectively can avoid the gas administration in the process of discharging water, stopped drilling gas in the process that discharges water and entered tunnel by tailrace, caused gas exceeding limit accident; Simplify the programmed sequence of operations of the personnel of discharging water, improve working efficiency.
