Structure under the pneumatic stopping valve opening that Fig. 2 is provided for the specific embodiment of the invention cuts open figure；
Fig. 3 is that the structure of the valve pocket of pneumatic stopping valve in Fig. 2 cuts open figure.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As shown in Figures 2 and 3, embodiments of the invention provide a kind of pneumatic stopping valve, including：Pneumatic housing 1, push rod 2,
Valve pocket 3 and valve element 4, valve pocket 3 include the end 32 of first end 31 and second, are provided between the end 32 of first end 31 and second of valve pocket
The axially extending bore 33 at connection first end 31 and second end 32, is additionally provided with the radial direction through hole connected with axially extending bore 33 on valve pocket
34, push rod 2 passes through in the axially extending bore 33 that first end 31 stretches into valve pocket 3 from pneumatic housing 1, and valve element 4 is arranged at the axle of valve pocket 3
To in through hole 33, valve element 4 is located between the end 32 of push rod 2 and second, and valve element 4 is slidingly sealed with valve pocket 3 and is connected；The axial direction of valve pocket 3
Being provided with through hole 33 allows push rod 2 to pass through but prevent the position limiting structure 331 that valve element 4 passes through, and position limiting structure 331 is located at first end
Between 31 and radial direction through hole 34, valve element 4 is located between the end 32 of position limiting structure 331 and second；Pneumatic housing 1 away from valve pocket 3 one
The distance between end and position limiting structure 331 are more than the length of push rod 2.
Preferably, in the embodiment, as shown in Fig. 2 pneumatic housing 1 is formed by upper shell 11 and the snapping of lower house 12, gas
Leather cup 5 is provided with dynamic shell 1, the edge of leather cup 5 is sandwiched in be formed between upper shell 11 and lower house 12 and is tightly connected, upper shell
11 have air inlet 111, and lower house there is push rod to export 121, platen 6 is provided between leather cup 5 and lower house 12, on platen 6
Be connected with push rod 2, push rod 2 from the axially extending bores 33 that push rod outlet 121 is stretched out and stretches into valve pocket 3, platen 6 and lower house 12 it
Between be provided with back-moving spring 7.
Preferably, the pneumatic stopping valve that the embodiment is provided also includes：Valve body 8 and valve seat 9, as shown in Fig. 2 on valve body 8
With valve pocket 81, entrance 82 and outlet 83, entrance 82 is vertically arranged and is respectively communicated with valve pocket 81 with outlet 83；Valve seat 9 is arranged at
It is tightly connected with valve body 8 in valve pocket 81；Valve pocket 81 is stretched into from the opposite end of entrance 82 and connected with valve seat 9 in second end 32 of valve pocket 3
Connect, the outlet 83 at valve seat 9 second end 32 and valve body 8 of connection valve pocket 3 in valve pocket 81, the first end 31 of valve pocket 3 is outer with pneumatic
Shell 1 is connected, and the radial direction through hole 34 of valve pocket 3 is connected with the outlet 83 of valve body 8.
The course of work below by way of pneumatic stopping valve is specifically described to the present embodiment, referring to Fig. 2, works as air inlet
111 when being passed through gas, and gas push leather cup 5 applies pressure to platen 6, and platen 6 overcomes the resistance force pushing mandril 2 of back-moving spring 7
To the direction of valve element 4 move, until push rod 2 promote valve element 4, valve element 4 is in close contact with valve seat 9, at this moment valve element 4 make valve seat 9 and
Outlet 83 disconnects, and then entrance 82 is disconnected with outlet 83, and the high-pressure fluid entered from entrance 82 is cut off.When air inlet 111
Stopping is when being passed through gas, in the presence of back-moving spring 7, platen 6, push rod 2 and the side of upper shell 11 from leather cup 5 to pneumatic housing 1
To reset, the entrance 82 of valve body 8 enters high-pressure fluid, promotes valve element 4 to be slided to the direction of position limiting structure 331, when valve element 4 is limited
When structure 331 stops that stopping is slided, valve element 4 is separated with push rod 2.Because position limiting structure 331 blocks valve element 4 to pneumatic housing 1
Direction is slided, therefore avoids valve element 4 and skid off valve pocket 3, and high-pressure fluid acts on spacing knot to the pressure of valve element 4 by valve element 4
On structure 331, now push rod 2 and valve element 4 are separated, and push rod 2 is not acted on by high pressure, and then push rod 2 will not be produced to pneumatic housing 1
High pressure thrust is given birth to, therefore push rod 2 and pneumatic housing 1 avoid being badly damaged under high pressure effect or even are beaten and fly.
Preferably, diameter of the diameter of push rod 2 less than valve element 4, valve pocket 3 is between first end 31 and position limiting structure 331
Internal diameter it is corresponding with the diameter of push rod 2, the diameter of internal diameter of the valve pocket 3 between the end 32 of position limiting structure 331 and second and valve element 4
It is corresponding.It follows that internal diameter of the valve pocket 3 between first end 31 and position limiting structure 331 is less than the end of position limiting structure 331 and second
Internal diameter between 32, as shown in figure 3, axially extending bore 33 just can be realized limiting the function that valve element 4 passes through by a reducing, this
Simple structure, beneficial to processing.The internal diameter of the diameter of other push rod 2 and the diameter of valve element 4 respectively with valve pocket 3 is corresponding, it is ensured that
Push rod 2 and valve element 4 are intact with the cooperation of valve pocket 3.
Specifically, valve element 4 is solid construction near one end of push rod 2.Avoid during push rod 2 snaps in valve element 4, it is ensured that top
Bar 2 can be completely separable with valve element 4.
Specifically, sealing ring 84, wherein valve element 4 are provided between valve element 4 and valve pocket 3 and between valve seat 9 and valve body 8
Excircle on there are two annular seal grooves, sealing ring 84 is set in annular seal groove.Position limiting structure 331 and radial direction through hole 34
The distance between equal to valve element 4 length.Avoid the stroke that valve element 4 moves in valve pocket 3 long, reduce sealing ring 84
Abrasion.
Specifically, the edge of leather cup 5 has boss 51, and boss 51 is stuck in the outer side edges of upper shell 11 and lower house 12.Enter
One step avoids leather cup 5 and is surprisingly come off with upper shell 11 and lower house 12, it is ensured that the sealing of stabilization.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
