Description
Technical field
The utility model relates to high-pressure pneumatics field more particularly to a kind of one-stroke energy conservation Pneumatic reversal valve structures.
Background technique
Engineering in practice, has many fields for utilizing high pressure gas, pressure is from more than ten megapascal to several hundred megapascal.Usually benefit
Low-pressure gas is set to be pressurized to required pressure with Pneumatic booster pump.Pneumatic booster pump be not necessarily to power supply, using compressed air as
Power source, the pressure of available up to several hundred megapascal.It is small in size, safety anti-explosive, and output pressure and flow can be with stepless-adjustments
Section, the multiple gases such as compressible nitrogen, hydrogen, oxygen, carbon dioxide are widely used in the various occasions for needing high pressure gas.But
Being existing Pneumatic booster pump all provides driving gas in compression travel and suction stroke, and after finishing function will driving gas it is whole
It is discharged in atmosphere, causes booster pump air consumption excessive, greatly waste the energy, increase economic cost.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, a kind of one-stroke energy conservation gas control is provided and is changed
To valve arrangement, which realizes one-stroke gas supply, saves the consumption of suction stroke gas, and structure is simple, easy to make.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: one-stroke energy conservation Pneumatic reversal valve knot
Structure, include valve body, air inlet, rod chamber, rodless cavity, the first stomata, the second stomata, third stomata, the 4th stomata, valve pocket,
Spool, intermediate sleeve, valve rod；The valve body is hollow structure cylinder valve body, which, which is provided with, is separately connected two drive of connection
It takes offence the air inlet of chamber；The valve body is arranged in the air inlet other side in rod chamber and rodless cavity；The rod chamber and valve body connect
It connects place valve interior wall both sides and is equipped with the first stomata, the second stomata；The rodless cavity is equipped with valve body junction valve interior wall both sides
Third stomata, the 4th stomata；The valve pocket is the guard member being fastened by bolts on valve interior wall；The spool is that setting exists
Hollow member in valve pocket, the spool face are along the circumferential direction provided with gas vent；The centre is set on valve core inside, in this
Between set connection rod chamber and rodless cavity；The valve rod is mounted on spool, and extends valve body one end.
Preferably, being equipped with sealing ring at gap between the valve pocket and valve body.
The beneficial effects of the utility model are: the structure realizes one-stroke gas supply, disappearing for suction stroke gas is saved
Consumption, and structure is simple, it is easy to make.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is Pneumatic reversal valve structural schematic diagram.
Wherein: 1 is valve body, and 2 be air inlet, and 3 be rod chamber, and 4 be rodless cavity, and 5 be the first stomata, and 6 be the second stomata, 7
It is the 4th stomata for third stomata, 8,9 be valve pocket, and 10 be spool, and 11 be intermediate sleeve, and 12 be valve rod.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of one-stroke energy conservation Pneumatic reversal valve structure, includes valve body 1, air inlet 2, rod chamber 3, nothing
Rod cavity 4, the first stomata 5, the second stomata 6, third stomata 7, the 4th stomata 8, valve pocket 9, spool 10, intermediate sleeve 11, valve rod 12；Institute
Stating valve body 1 is hollow structure cylinder valve body, which is provided with the air inlet 2 for being separately connected two driving air cavity of connection；Institute
Valve body 1 is stated to be arranged in 2 other side of air inlet in rod chamber 3 and rodless cavity 4；The rod chamber 3 and 1 junction valve interior wall of valve body
Both sides is equipped with the first stomata 5, the second stomata 6；The rodless cavity 4 is equipped with third stomata with 1 junction valve interior wall both sides of valve body
7, the 4th stomata 8；The valve pocket 9 is the guard member being fastened by bolts on 1 inner wall of valve body；The spool 10 is to be arranged in valve
Hollow member in set 9, which is along the circumferential direction provided with gas vent；The intermediate sleeve 11 is arranged in spool 10
Portion, the intermediate sleeve 11 are connected to rod chamber 3 and rodless cavity 4；The valve rod 12 is mounted on spool 10, and extends 1 one end of valve body.
When it is implemented, being equipped with sealing ring at gap between the valve pocket 9 and valve body 1.
When practical operation, after connecting driving gas source, gas source enters 10 left end of spool all the way, and spool 10 is pushed to be located at right position,
The annular chamber and the second stomata 6 that another way drives gas to pass through outside spool 10 enter rodless cavity 4, carry out compression pressurization stroke,
First stomata 5 is closed, and gas is discharged through the annular space between the 4th stomata 8 and valve rod 12 and intermediate sleeve 11 in rod chamber 3；
Compression travel end, right pilot valve are touched, and gas source enters 10 right side of spool, push spool 10 to be moved to left position, air inlet 2 is sealed
It closes, gas enters rod chamber through annular chamber, the third stomata 7 between the first stomata 5, intermediate sleeve 11 and spool 10 in rodless cavity 4
3, piston carries out suction stroke under admission pressure effect.
