Component has the function of cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting or overflow pressure relief etc..For fluid control systems
Valve, various valves, kind and specification used in from simplest shut-off valve to extremely complex robot control system(RCS) are quite numerous
It is more.
With the rapid development of science and technology, higher and higher for the seal request of valve, but work as various operating conditions and mouth
When the precision of the sealing surfaces such as diameter is difficult to reach requirement, valve not can guarantee the reliability of sealing.
Utility model content
The purpose of this utility model is to provide a kind of air sealed valves, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of air sealed valve, including valve body, institute
It states and is provided with valve rod on valve body, valve body is internally provided with valve plate, and the two sides of valve body are provided with valve body inflation inlet, valve body and valve
The junction of body inflation inlet is provided with valve seat, and the bottom end of the valve rod is provided with valve stem inflation inlet.
As a further solution of the present invention: being provided with outer groove on the valve seat, it is provided on the outer groove
Venthole.
The two sides of the valve body are provided with first flange, first method as a further solution of the present invention,
Adapter tube is provided on orchid.
There are two the valve stem inflation inlet is arranged altogether as a further solution of the present invention, two valve rods
Portion's inflation inlet is separately positioned on the both ends of valve rod.
Compared with prior art, the utility model has the beneficial effects that being provided with valve body inflation inlet, valve body on valve
Inflation inlet can form gas shield annulus at the sealing surface of valve seat and valve plate, to prevent medium from valve seat and valve plate
Sealing surface overflows, and then achievees the effect that sealing, makes the better tightness of valve, secondly, being also provided with valve stem on valve
Inflation inlet, valve stem inflation inlet can guarantee that medium and particulate matter will not blow into valve pocket and cause to wear to valve rod, and can protect
Sealing at card filler keeps the sealing of valve relatively reliable to further increase the sealing effect of valve.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-6 is please referred to, the utility model provides a kind of technical solution: a kind of air sealed valve, including valve body 1, valve body 1
On be provided with valve rod 2, valve body 1 is internally provided with valve plate 3, and the two sides of valve body 1 are provided with valve body inflation inlet 5, valve body 1 and valve
The junction of body inflation inlet 5 is provided with valve seat 4, and the bottom end of valve rod 2 is provided with valve stem inflation inlet 6, in order to make valve seat 4
Using effect it is more preferable, in the present embodiment, it is preferred that be provided with outer groove on valve seat 4, be provided with venthole on outer groove, lead to
Stomata is provided with multiple, and each venthole corresponds again draws from valve seat 4, and the position of extraction is provided with the second annular groove, in order to
Keep the function of valve body 1 more abundant, in the present embodiment, it is preferred that the two sides of valve body 1 are provided with first flange, first flange
On be provided with adapter tube;
Fig. 3 and Fig. 4 are please referred to, it is excellent in the present embodiment in order to make valve stem inflation inlet 6 use enhanced convenience
Choosing, for valve stem inflation inlet 6 altogether there are two settings, two valve stem inflation inlets 6 are separately positioned on the both ends of valve rod 2, valve
Bar portion inflation inlet 6 can guarantee that medium and particulate matter will not blow into valve pocket, cause to wear to valve rod 2, and can guarantee at filler
Sealing, valve body 1 welds lining structure using plate, wherein main body and the weldering of two first flange groups, cylinder and wears shaft portion up and down and adopts
It is welded with group, is welded with reinforcing rib on valve seat 4, reinforcing rib can reinforce valve seat 4, and to lining is carried out in cylinder, play
Wear-resisting and heat-blocking action.
The working principle and process for using of the utility model: the air sealed valve of the utility model is applied to have gas source work
In environment under condition, gas is filled in valve seat 4 using external inflation flange by valve body inflation inlet 5 by user when use, this
When gas passed through from the venthole on valve seat 4, at this time gas by the second annular groove and venthole valve seat 4 and valve plate 3 sealing
Annular inflatable area is formed at face, the pressure in the annular inflatable area is higher than the pressure of medium, therefore, even if valve plate 3 does not have with valve seat 4
