Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
Embodiment one
As shown in Fig. 1 to 7, a kind of gas control linkage valve gear, comprising: valve body 1 and piston piece 3.
Valve body 1 is equipped with air inlet I109, gas outlet I102, air inlet II106 and gas outlet II105；Air inlet I109 and
It is connected with air flue 101 between the I102 of gas outlet, plunger shaft 104, piston are connected between air inlet II106 and gas outlet II105
Chamber 104 is connected by connecting hole 103 with air flue 101；Piston piece 3 is slidingly sealed in plunger shaft 104, and piston piece 3 is close to gas
The end in road 101 can be moved to position two by position one under the gas pressure in air flue 101；Piston piece 3 is in position one
When, gas outlet II105 is connected with air inlet II106, when piston piece 3 is in position two, gas outlet II105 and air inlet
II106 phase blocks.
Piston piece 3 is moved on to by position one to position two under the positive pressure in air flue 101, when positive pressure disappears or subtracts
It is weak, in order to enable piston piece 3 to be returned to position one, return unit 4 is additionally provided in valve body 1.Return unit 4 is set in plunger shaft 104
And be connected with piston piece 3, piston piece 3 can have the trend mobile to position one from position two under the action of return unit 4.It is multiple
Position part 4 is spring, and piston piece 3 is equipped with auxiliary section 303 far from the end of air flue 101, and one end of return unit 4 is sheathed on auxiliary section
303 periphery and the end face for contacting 303 root of portion, the other end abut the corresponding end of plunger shaft 104.In return unit
Under the action of 4, piston piece 3 can return back to position one by position two under its resilient force.
In the present embodiment, piston piece 3 includes the piston I 301 abutted against and piston I I302, and piston I 301 is close to air flue
Far from air flue 101, piston I 301 can be mobile to 101 direction of air flue under the suction function of air flue 101 by 101, piston I I302.
Due to the constraint connected between not having between piston I 301 and piston I I302, in the state of as shown in Figure 6, piston
I301 is mobile by gas pressure and piston I I302 is driven to move in the same direction, but in the state of as shown in Figure 7, piston I 301 exists
It is resetted under suction function, and piston I I302 then resets under the action of return unit 4.
Gas circuit connection and blocking between air inlet II106 and gas outlet II105 are by piston I I302 and plunger shaft
What the sealing between 104 was realized, specifically, the outer peripheral surface of piston I I302 is equipped with a seal groove I305, sets in seal groove I305
There is sealing ring I6, piston piece 3 is slidingly sealed by sealing ring I6 and the composition of plunger shaft 104；Piston piece 3 is in position for the moment, close
Sealing ring I6 in sealing groove I305 is located at the side of air inlet II106 or gas outlet II105 to make to import and export II106 and outlet
Mouth II105 is connected；When piston piece 3 is in position two, the sealing ring I6 in seal groove I305 is located at air inlet II106 and outlet
It is obstructed to make to import and export II106 with gas outlet II105 phase between mouth II105.
Outlet pressure is influenced in order to avoid converging from air inlet I109 and the two air-flows generation entered from air inlet II106
Power, therefore air flue 101 and plunger shaft 104 spatially form barrier, specifically, the outer peripheral surface of piston I I302 is additionally provided with one
Seal groove II304, seal groove II304 opposing seal slot I305 are close to piston I 301；Sealing ring II5 is equipped in seal groove II304,
Two parts that sealing ring II5 divides plunger shaft 104 mutually to obstruct.
Plunger shaft 104 includes the cavity I1041 and cavity II1042 being connected, cavity I1041 connection air flue 101, cavity
II1042 connection inlet, outlet II106,105, piston I 301 is in the internal slide of cavity I1041, and piston I I302 is in cavity
The internal slide of II1042；Cavity I1041 is equipped with forward and backward confined planes 108,107, piston on the moving direction of piston I 301
Position corresponding position one when I301 and front limit face 108 contact, position corresponding position when being contacted with rear confined planes 107
Two.Valve body 1 can carry out seperated design in the plane where rear confined planes 107, thus formed two can with the valve block of assembly and connection,
Convenient for the installation of internal part.
As a kind of gas circuit structure, the vertical connection cavity 104 of air flue 101, gas outlet II105 and air inlet II106 hang down
Straight connection cavity 104, has certain distance S between the center line of gas outlet II105 and the center line of air inlet II106；Air inlet
Mouth I109 is equipped with inlet suction port 2, and 2 center of inlet suction port is equipped with the air intake duct 201 of connection air flue 101.
As shown in fig. 6, air inlet I109 and air inlet II106 connect gas source respectively, and when gas outlet I102 is blocked, air flue
Air-flow in 101 can not normally be discharged increase the air pressure in air flue 101, and gas pressure is in the piston I 301 of piston piece 3
End face, as pressure is gradually increased, piston piece 3 is whole to be moved to position two by position one, at this time air inlet II106 and outlet
Gas circuit between mouth II105 is obstructed by the sealing ring I5 on piston piece 3, and gas outlet II105 is closed at this time.
As shown in fig. 7, the air pressure in air flue 101 restores and normal outlet, originally at this time after gas outlet I102 is opened
The pressure acted on piston piece 3 disappears, and piston piece 3 is moved to position one by position two under the resilient force of return unit 4,
During this, the gas circuit between gas outlet II105 and air inlet II106 is connected to again, so that gas outlet II105 be made normally to go out
Gas.
Embodiment two
As shown in figure 8, the difference is that, in the present embodiment, piston piece 3 includes 301 He of piston I being fixedly connected with embodiment one
Piston I I302, piston piece 3, which is integrated to be manufactured or use by piston I 301 and piston I I302, the modes such as welds, is spirally connected
Made of being connected.The external force that place one by one is subject in this way, which piston piece 3 is taken up an official post can drive piston piece 3 mobile.Piston I 301
Close to air flue 101, it is used to bear to play the gas pressure in 101, piston I I302 is used to receive reset far from air flue 101
The resilient force of part 4.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
