Description
Technical field
The invention belongs to technical field of valve manufacturing, and in particular to a kind of design of air sealed valve.
Background technique
Valve is for being opened and closed pipeline, control flow direction, the parameter (temperature, pressure and flow) of regulation and control pumped (conveying) medium
Pipeline fittings shut-off valve, check-valves, regulating valve etc. can be divided into according to its function, valve is the control in fluid delivery system
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.
Summary of the invention
The purpose of the present invention is to provide a kind of designs of air sealed valve, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme: a kind of design of air sealed valve, including valve body,
Be provided with valve rod on the 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 with
The junction of valve body inflation inlet is provided with valve seat, and the bottom end of the valve rod is provided with valve stem inflation inlet, the valve body
Two sides are provided with first flange, and adapter tube is provided in the first flange.
As a further solution of the present invention: being provided with outer groove on the valve seat, ventilation is provided on the outer groove
Hole.
As further scheme of the invention: there are two the valve stem inflation inlet is arranged altogether, two valve stems are filled
Gas import is separately positioned on the both ends of valve rod.
Compared with prior art, the beneficial effects of the present invention are: being provided with valve body inflation inlet on valve, valve body inflation
Import can form gas shield annulus at the sealing surface of valve seat and valve plate, to prevent medium from the sealing of valve seat and valve plate
Face is overflowed, and then achievees the effect that sealing, makes the better tightness of valve, secondly, being also provided with valve stem inflation on valve
Import, 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 guarantee and fill out
Sealing at material keeps the sealing of valve relatively reliable to further increase the sealing effect of valve.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6 is please referred to, the present invention provides a kind of technical solution: a kind of design of air sealed valve, including valve body 1, valve
Valve rod 2 is provided on body 1, 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
The junction of valve body inflation inlet 5 is provided with valve seat 4, the bottom end of valve rod 2 is provided with valve stem inflation inlet 6, in order to make valve
The using effect of seat 4 is more preferable, in the present embodiment, it is preferred that and it is provided with outer groove on valve seat 4, is provided with venthole on outer groove,
Venthole be provided with it is multiple, each venthole correspond again from valve seat 4 draw, the position of extraction is provided with the second annular groove, is
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, the first method
Adapter tube is provided on orchid;
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 of the invention and process for using: air sealed valve of the invention is applied to the ring under gas source operating condition
In border, gas is filled in valve seat 4 using external inflation flange by valve body inflation inlet 5 by user when use, at this time gas from
Venthole on valve seat 4 passes through, and gas is formed at the sealing surface of valve seat 4 and valve plate 3 by the second annular groove and venthole at this time
Annular inflatable area, the pressure in the annular inflatable area are higher than the pressure of medium, therefore, valve plate 3 is not bonded with valve seat 4 not
Dielectric leakage in valve chamber can be come out, to prevent medium from overflowing from the sealing surface of valve seat 4 and valve plate 3, and then reach sealing
Effect, valve stem 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 protect
Demonstrate,prove the sealing at filler.
