Description
Technical field
The present invention relates to a kind of valve, more particularly to a kind of pressure-gradient control valve.
Background technology
Current pipeline shunt mainly by manually controlling or the structure of electrically operated valve etc is coordinated, realizes pipeline
Flow-dividing control, however control mode, that is, complicated, and complicated control or manpower.
With the complication of the modern life, the diversification of demand of pipeline, also, with the deep masses of various products,
Structure needs after simplifying, could be with cheaper cost input market, for public use.
And documents CN201610315569.6, a kind of Automatic temp. adjusting valve provided mainly pass through memorial alloy
The adjusting of temperature is completed, no doubt more convenient in this way, but its structure is complex, and with the aging of memorial alloy, can not
It is alternative to cause, once ging wrong, then it may require that whole part is replaced, it is not only troublesome in this way, and more cost of idleness,
Also, since it is mainly adjusted by memorial alloy, still, it is easy to be protected from environmental for memorial alloy, causes to be not allowed
Really, and it is unfavorable for long-term use.
Invention content
The goal of the invention of the present invention is provided a kind of preferential to solve the problems, such as that existing pipeline preferentially distributes the regulation and control of flow
Valve.
In order to achieve the above-mentioned object of the invention, present invention employs following technical schemes：
A kind of pressure-gradient control valve, including valve body, movable sealing block, elastic component and matching casing；The valve body is three-way pipe structure, including
First into valve port, second into valve port, go out valve port, barrier recirculation hole and movable inner cavity；There are two the barrier recirculation hole is set, respectively
Both ends positioned at movable inner cavity；The movable sealing block is located in movable inner cavity, and between two barrier recirculation holes；It is described
Elastic component is located between movable sealing block and one of barrier recirculation hole, and the matching casing is socketed with valve port is gone out, described
It is hollow with casing, and it is equipped with out valve nozzle.
As preferred：It is additionally provided with barrier flowing plate in the matching casing.
As preferred：Described first into valve port, second into valve port and goes out valve nozzle and is separately connected external pipe.
As preferred：The movable sealing block bottom opposite with valve port is gone out, which is equipped with, to be evacuated, to reduce friction and consumptive material,
It improves using effect and saves unnecessary waste.
As preferred：Enclosed indent hollow cavity is formed between the barrier flowing plate, movable inner cavity and barrier recirculation hole
Room, the movable sealing block are active among indent hollow chamber, are stopped by barrier flowing plate and barrier recirculation hole, can not take off
From indent hollow chamber.
As preferred：Its length of the activity inner cavity is longer than the length of at least two movable sealing blocks.
As preferred：The length of the movable sealing block is more than the outer diameter of barrier flowing plate, avoids out in valve nozzle simultaneously, stream
Go out first into valve port and second into the external water pipe of valve port, obscured with the water source for preventing its different, and cannot achieve effective
Switch shunt conduit effect.
As present invention further optimization：The elastic component is located at by first into valve port side, then first is excellent into valve port
Apex, has an effect of priority discharging, and the other end second is then secondary end into valve port, conversely, second into valve port being then preferential
End, and first into valve port be secondary end；The hydraulic pressure of the secondary end is more than, the preferential pressure phase for holding hydraulic pressure and elastic component to be rebounded
When the pressure added, the movable sealing block close to secondary end could be forced movable sealing block to carry out by the hydraulic pressure from secondary end
Toward the activity of preferential end, at this point, going out water that valve port the is gone out then external water pipe from secondary end；The hydraulic pressure preferentially held and elasticity
The pressure that the pressure that part is rebounded is added, when being more than the hydraulic pressure of secondary end, then movable sealing block remains close to the position of secondary end,
Then at this point, going out water that valve port is gone out then from the external water pipe preferentially held.
Compared with prior art, a kind of pressure-gradient control valve for using above-mentioned technical proposal, has the advantages that：
One, movable sealing block is forced to carry out displacement using pressure, after generating effective displacement, movable sealing block can be blocked separately
The weaker pipeline opening of one hydraulic pressure.
Two, by detachable structure, convenient for structure installation and prevent movable sealing block from dropping out.
Three, by the elastic force of elastic component, preferential end is helped to reduce the oppressive force from secondary end, to be provided to preferential end
Additional elastic force.
