Description
Technical field
The present invention relates to a kind of global function high pressure valve sealing structures, belong to pressure valve equipment technical field.
Background technology
At present in some media transport, transfers for having preferable mobility etc. in operations, mainly by pressure pipeline into
Capable, in order to improve control performance of the medium in transport process, all kinds of control valves are usually set on transfer pipeline to conveying
Process is managed and controls, but is found in real work, and the valve seat of currently used valve arrangement is generally " Z " font
Structure and " S " font structure, and seal member is mainly non-metal elastic gasket seal, therefore leads to high pressure valve in operational process
The abrasion of middle valve seat is often more serious, and the elastic deformation ability and anti-pressure ability of valve seat are relatively weak, therefore causes currently to press
The operation stability and reliability of power valve are poor, and leakage phenomenon easily occurs due to pressure is excessive or usage time is longer, because
There is an urgent need to develop go out a kind of completely new pressure valve arrangement to meet the needs of actual use for this.
Invention content
The object of the present invention is to provide the present invention to provide a kind of global function high pressure valve sealing structure.
In order to achieve the above object, the present invention provides following technical solution:
A kind of global function high pressure valve sealing structure, including valve seat and spool, valve seat is connect with spool, and is connected by cavity
Logical, valve seat includes metal seat valve and nonmetallic valve seat, wherein metal seat valve totally two, and be bolted, nonmetallic valve seat
Only one position and sets diversion cavity, nonmetallic valve seat center line and two gold medals between two metal seat valves between two metal seat valves
Belong to valve seat line of symmetry to overlap, metal seat valve and nonmetallic valve seat are all provided with sealing surface, and the sealing of metal seat valve and nonmetallic valve seat
Face is respectively positioned in same plane, and is offseted with spool.
Further, the valve seat is first respectively processed metal seat valve and nonmetallic valve seat, so in processing
Afterwards sealing surface will be processed unified after metal seat valve and the assembling of nonmetallic valve seat.
Further, the nonmetallic valve seat is resilient nonmetallic material.
Further, the nonmetallic valve seat is modified rubber.
Present device is simple in structure, produces and easy to use and of low cost, while separately has good structure
Intensity, wear resistance and sealing performance, and meet an urgent need resilience with good failure, so as to help to improve high pressure valve
Operation stability and reliability.
Description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the method for the present invention flow chart.
Specific embodiment
Technical scheme of the present invention is clearly and completely described below in conjunction with the attached drawing of the present invention, it is clear that retouched
The embodiment stated is only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill all other embodiments obtained without creative efforts, belong to the present invention
The range of protection.
A kind of global function high pressure valve sealing structure as shown in Figure 1, including valve seat 1 and spool 2, valve seat 1 connects with spool 2
It connecing, and passes through cavity 3 and connect, valve seat 1 includes metal seat valve 11 and nonmetallic valve seat 12, wherein metal seat valve 11 totally two, and
It is bolted, nonmetallic 12 only one of valve seat, the position and between two metal seat valves 12 between two metal seat valves 12
If diversion cavity 4, nonmetallic 12 center line of valve seat is overlapped with two metal seat valves, 11 line of symmetry, metal seat valve 11 and nonmetallic valve seat equal 12
If sealing surface 13, and the sealing surface 13 of metal seat valve 11 and nonmetallic valve seat 12 is respectively positioned in same plane, and with 2 phase of spool
It supports.
In the present embodiment, the valve seat 1 first respectively carries out metal seat valve 11 and nonmetallic valve seat 12 in processing
Processing processes sealing surface 13 after then assembling metal seat valve 11 and nonmetallic valve seat 12 unified.
In the present embodiment, the nonmetallic valve seat 12 is resilient nonmetallic material.
In the present embodiment, the nonmetallic valve seat is modified rubber.
The present invention in actual use, medium flow direction closed for stream, medium after valve by core toward valve seat flow away when, medium
On the most of metal seat valve of active force effect, make the smaller not easy damaged of the pressure that nonmetallic valve seat is born, simultaneously because nonmetallic
Valve seat has larger elastic deformation ability, therefore when medium High Pressure Difference, nonmetallic valve seat is vulnerable to damage, when non-gold
After category valve seat is damaged, metal seat valve continues to play sealing function and can bear larger pressure differential, close so as to reach raising valve seat
Sealing property and fault-resistant damage ability, realize that valve seat is not damaged in High Pressure Difference, the requirement of zero leakage.
Present device is simple in structure, produces and easy to use and of low cost, while separately has good structure
Intensity, wear resistance and sealing performance, and meet an urgent need resilience with good failure, so as to help to improve high pressure valve
Operation stability and reliability.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can readily occur in change or replacement, should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention described should be subject to the protection scope in claims.
