Outside is provided with the back-moving spring 4 for making wedge shape valve core 2 reset；
Valve in the on state, pipeline and formation fluid passage, cavity 101 bottom；
In closed state, wedge shape valve core 2 bottom surface contacts valve with cavity 101 bottom surface, and by catch means by wedge shape
Spool 2 blocks.
Valve includes valve body 1, wedge shape valve core 2, catch means and back-moving spring 4, and wedge shape valve core 2 is upper and lower in cavity 101
The on off state of Mobile control valve door.When wedge shape valve core 2 moves to the top of cavity 101, valve is opening, pipeline and
Formation fluid passage, cavity 101 bottom, wedge shape valve core 2 both sides contact with catch means, catch means attonity, wedge shape valve core 2
The elastic force holding position relying on back-moving spring 4 is fixed, and back-moving spring 4 arranges the outside of pull bar 401, and pull bar 401 is arranged on wedge
The upper end of shape spool 2；When wedge shape valve core 2 moves to the bottom of cavity 101, valve is closed mode, and now catch means is moved
Make, wedge shape valve core 2 position locked, it is impossible to mobile, back-moving spring 4 in compressive state, fluid passage closure.
Wherein, spool is set to wedge shape valve core 2, and the purpose so arranged is, when wedge shape valve core 2 moves to low side,
Wedge shape valve core 2 relies on wedge-type shape can fit tightly bottom cavity 101, therefore need not the sealing devices such as pad；Existing
In technology, the leakage of valve causes because of pad corrosion mostly, and therefore, the valve that this utility model provides can be accomplished corrosion-resistant,
It is difficult to reveal.
It is pointed out that does not has concrete shape to specify for wedge-type shape, as long as so wide shape in narrow one end, one end
Shape all can be regarded as wedge shape.
It may also be noted that pipeline is divided into water inlet pipe 103 and outlet pipe 104.
In the alternative of the present embodiment, wedge shape valve core 2 grinds through precision with the contact surface of pipeline end face.
When wedge shape valve core 2 moves to low side in cavity 101, wedge shape valve core 2 will contact with pipeline end face, this be contacted
Face is through precision milled processed, it is ensured that the sealing of valve, prevents from revealing.The pad of difference prior art, the pad of prior art
Sheet is easily corroded, and once corrosion valve entirety will be unable to ensure sealing property.
When it is pointed out that actually used, wedge shape valve core 2 only needs the contact surface and and chamber with water inlet pipe 103 end face
Body 101 base contact surface precision is ground.
In the alternative of the present embodiment, catch means is arranged in lock-bit hole 3；
Catch means horizontal positioned；
Catch means is arranged on above pipeline.
It is pointed out that and catch means is arranged on above pipeline, carry out reasonable layout, enable catch means normal
Use, horizontal positioned catch means simultaneously, make catch means preferably reach lock-bit effect.
It may also be noted that catch means is for locking wedge shape valve core 2, stationary wedge spool 2.
In the alternative of the present embodiment, catch means includes screw 301, lock-bit spring 302 and pin 303；
Lock-bit spring 302 is arranged in the middle of pin 303 and screw 301；
Screw 301 is connected with wedge shape valve core 2.
When valve is in opening, when i.e. wedge shape valve core 2 is positioned at cavity 101 top, pin 303 is against wedge valve
Core 2 both sides；When valve is closed, when i.e. wedge shape valve core 2 is positioned at bottom cavity 101, pin 303 is by lock-bit spring
The elastic force effect of 302 is stretched out, and coordinates with wedge shape valve core 2, makes wedge shape valve core 2 again can not increase under the effect of back-moving spring 4,
Play good Lock function.
It is pointed out that valve reopens from closing to, need first to disassemble screw 301, make lock-bit spring
302 elasticity recoveries, take out pin 303, and wedge shape valve core 2 moves up according to back-moving spring 4, makes valve reach opening,
The most again pin 303, back-moving spring 4 and screw 301 are put back in lock-bit hole 3 successively, wait the closedown of valve next time.
In the alternative of the present embodiment, catch means includes ratchet 311 and ratchet 312；
Pawl slot 310 is had on cavity 101；
Ratchet 311 is arranged in pawl slot 310.
When valve is in opening, when i.e. wedge shape valve core 2 is positioned at cavity 101 top, ratchet 311 is against wedge shape valve core
2 both sides；When valve is closed, when i.e. wedge shape valve core 2 is positioned at bottom cavity 101, wedge shape valve core 2 to glide time, warp
Cross ratchet 311, ratchet 311 by with the coordinating of ratchet 312, make wedge shape valve core 2 again cannot go up under the effect of back-moving spring 4
Rise, play good Lock function.
In the alternative of the present embodiment, below pipeline, it is provided with overflow launder 105；
The bottom of cavity 101 is provided with accommodating a small amount of liquid flooding groove 105, it is ensured that water inlet pipe 103 and overflow launder
105 pressure at two ends balances.
Owing to having overflow launder 105 bottom cavity 101；When valve is in opening, overflow launder is inoperative；When
When valve is closed, water inlet pipe 103 is sealed by wedge shape valve core 2；Owing to water inlet pipe 103 pressure is excessive, it is possible to can go out
Now a small amount of fluid leakage, when a small amount of liquid revealed enters overflow launder 105, water inlet pipe 103 is put down with overflow launder 105 pressure at two ends
Weighing apparatus, increases the tightness of valve.
In the alternative of the present embodiment, valve also includes sensor；
Sensor is arranged on pipeline；
Sensor electrically connects with power set.
Being arranged on by sensor on water inlet pipe 103, when the damaged appearance of water inlet pipe 103 is revealed, sensor is to power set
Send signal, after power set receive signal, carry out corresponding actions, move down offer power for wedge shape valve core 2.
In the alternative of the present embodiment, power set are set to air compressed package 501 and/or explosive；
Power set are arranged on wedge shape valve core 2 upper end.
It is pointed out that air compressed package 501 and/or explosive are arranged on the upper end of wedge shape valve core 2, place and cavity 101
In, when, after air compressed package 501 and/or explosive initiation, generation energy is in closing space, and only wedge shape valve core 2 can move,
Therefore enough power can be provided for wedge shape valve core 2.
In the alternative of the present embodiment, power set include depression bar 5 and power source；
Power source includes air compressed package 501 and/or explosive；
Power set are arranged on depression bar 5 top；
Depression bar 5 is hinged with valve body 1.
Power set are set to air compressed package 501 and/or explosive, when, after the signal receiving sensor conveying, igniting
Air compressed package 501 and/or explosive, produce power, and depression bar 5 is pushed to lower section, and depression bar 5 compression wedge spool 2 moves down, and makes
Valve closing.
It is pointed out that air compressed package 501 and/or explosive are arranged on the top of depression bar 5, when air compressed package 501
And/or after explosive initiation, depression bar 5 is depressed by the power of generation.
Also note that time, depression bar 5 is hinged with valve body 1, it is simple to the rotation of depression bar 5.
In the alternative of the present embodiment, the material of wedge shape valve core 2 is corrosion-resistant material.
The wedge shape valve core 2 of corrosion-resistant material is set, it is to avoid time practical, because corrosion causes wedge shape valve core 2 leakage phenomenon occur.
Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand: the technical scheme described in foregoing embodiments still can be modified by it, or to the most some or all of
Technical characteristic carries out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this practicality new
