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 the 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 the boring, when the water yield in the tailrace acquires a certain degree, needs the ponding in the tailrace is discharged by negative pressure pump drainage to tailrace.When manually discharging water, all need valve closing at every turn, open the operation that just can discharge water normally of distributing valve, discharging valve simultaneously pipeline side and boring side.The valve quantity that this operation worker need operate is many, and workload is big; Simultaneously, the valve closing of pipeline side and boring side, mash gas pumping drilling can not be realized continuous gas pumping between blowoff period, these situations all cause the present work of discharging water to have a strong impact on the efficient of whole gas pumping system.
So, in order when discharging water, to guarantee the continuous extraction of gas, increase work efficiency, be necessary existing mash gas pumping drilling jettison gear is improved.
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 a kind of integrated bypass two-position five-way negative pressure discharging valve is provided.
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 that inside offers the valve body of valve pocket, and 4 spools are installed in the valve pocket
,Be fixed with the valve rod of its rotation angle of control on the spool, valve body one side offers the identical boring inlet passage in aperture, the extraction outlet passage, the opposite side symmetry is offered the boring outlet passage of same apertures, the extraction inlet passage, offer the gas distribution channels of small aperture between two passages, offer passage identical with the gas distribution channels aperture and that communicate with the extraction inlet passage on the described spool, operating valve lever drives valve core rotation and enters the extraction position and discharge water the position, 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 be UNICOM not, the extraction outlet passage and the not UNICOM of inlet passage that holes, during described discharge water, extraction outlet passage and extraction inlet passage be UNICOM not, the boring inlet passage and the not UNICOM of outlet passage that holes, extraction outlet passage and boring inlet passage UNICOM, gas distribution channels and extraction inlet passage UNICOM.
The present invention adopts integrated valve, in valve inside respective via and closed-circuit system is set, and realizes in the process that discharges water, and the work of boring gas pumping does not stop.Working principle is: the valve working state has two, and the one, normal extraction position, the 2nd, the position discharges water; Five-way is for connecting the two logical and distributions that two of tailrace leads to, connects extraction arm, extraction boring.During the extraction position, drilled tunnel and drilled tunnel UNICOM, extraction passage and extraction passage UNICOM, gas distribution channels and drilled tunnel be UNICOM not, and drilled tunnel and extraction passage be UNICOM not, during described discharge water, drilled tunnel and the boring not UNICOM of passage that discharges water, extraction passage and extraction passage be UNICOM not, drilled tunnel and extraction passage UNICOM, gas distribution channels and drilled tunnel UNICOM.
The valve that The present invention be directed to present tailrace is many, do not have bypass, complicated and the novel valve of design of execute-in-place, with respect to existing valve, increase drilled tunnel and extraction passage two-way bypass, solved the problem that gas in the on-the-spot process that discharges water can not extraction, increased gas distribution channels road and drilled tunnel, solve the distribution automation issues, simplify valve quantity and be reduced to 1, valve is become one, be reduced to two of one by original 5.
The present invention has reduced the setting of gas distribution valve, has made things convenient for execute-in-place; Realized the continuous extraction in the process that discharges water, improved gas pumping efficient, can effectively avoid the gas management in the process of discharging water, the gas of having stopped to hole in the process of discharging water enters the tunnel by tailrace, causes the gas exceeding limit accident; Simplify the personnel's that discharge water programmed sequence of operations, improved working efficiency.
