Description
Technical field
The utility model relates to a kind of valve buck configuration more particularly to a kind of annular groove buck configurations of valve.
Background technique
Currently, with the continuous development of industry, requirement of the people for equipment just in the continuous improvement, including pipeline connection
The valve at place, since valve itself needs to bear the shadow of pressure, temperature and pipeline the fluctuation bring load from medium
Ring etc., so the requirement to valve is higher and higher, correspondingly, the design of trim has to comply with corresponding technical requirements, with
This adapts to different working condition requirements.
For valve, the leakproofness of sealing surface is to determine the key factor of the life of valve length, for a long time
Airtightness is not only to measure the reliability of valve mass, even more guarantees that this system is safe and reliable, premise of stable operation, institute
With for valve, one of the most important factor in service life is exactly the service life of sealing surface.Currently, due to the pressure ratio before and after valve
It is larger, cause the flow velocity for flowing through sealing surface higher, long-play goes down, valve sealing face certainly will be caused it is certain wash away,
Cause valve to generate leakage, influences the overall operation of system.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of annular groove pressure structures of valve, can pass through spool
The flow velocity of medium is substantially reduced with the annular groove design on valve seat, avoids the influence caused by sealing surface.
The utility model is to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of annular groove decompression of valve
Structure, including valve seat, spool and sleeve, wherein the inner wall of the valve seat and the outer wall of spool process same tilt angle respectively
The inclined-plane of degree circumferentially opens up to form multiple annular grooves on the inclined-plane, and the spool is arranged in sleeve, and the spool is along sleeve
It is axial to move up and down, sealing surface is formed on the sleeve.
Preferably, two inclined-planes in the spool outer wall and valve base inner wall have the same grade of tolerance.
Preferably, the annular groove is of the same size, and multiple annular grooves in the spool outer wall and valve base inner wall point
Open dislocation arrangement.
Preferably, the shape in the annular groove section is semicircle or polygon.
The utility model comparison prior art has following the utility model has the advantages that the annular groove of valve provided by the utility model is depressured
Structure substantially reduces the flow velocity of medium by the annular groove design on spool and valve seat, avoids impacting sealing surface, have
The features such as economic, reliable, the structure can be widely used on different valves, reduce the destruction of the sealing surface of valve, improve valve
The service life of door.
Detailed description of the invention
Fig. 1 is the annular groove buck configuration overall structure figure of the utility model valve；
Fig. 2 is the structure chart of the annular groove buck configuration spool of the utility model valve；
Fig. 3 is the structure chart of the annular groove buck configuration valve seat of the utility model valve.
In figure:
1 valve seat, 2 spool, 3 sleeve
4 inclined-plane, 5 annular groove, 6 sealing surface
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is the annular groove buck configuration overall structure figure of the utility model valve.
Referring to Figure 1, the annular groove buck configuration of valve provided by the utility model, including valve seat 1, spool 2 and sleeve 3,
Wherein, the inner wall of the valve seat 1 and the outer wall of spool 2 process the inclined-plane 4 of same tilt angle, edge on the inclined-plane 4 respectively
It circumferentially opens up to form multiple annular grooves 5, the spool 2 is arranged in sleeve 3, and the spool 2 is along the axial up and down motion of sleeve 3, institute
It states and is formed with sealing surface 6 on sleeve 3.
Fig. 2 is the structure chart of the bicyclic slot buck configuration spool of the utility model valve；Fig. 3 is the utility model valve
The structure chart of bicyclic slot buck configuration valve seat.
Continuing with referring to figs. 2 and 3, the inclined-plane 4 on 2 outer wall of spool and 1 outer wall of valve seat has same degree tolerance,
The annular groove 5 is of the same size, and multiple annular grooves 5 on 1 inner wall of 2 outer wall of the spool and valve seat separately arrange by dislocation,
The length on the inclined-plane 4, the depth of annular groove 5 and number can be designed according to pressure different before and after valve, temperature, medium type.
The utility model is by processing the identical inclined-plane 4 of angle in spool 2 and valve seat 1, and the inclined-plane 4 in process must
Palpus clamped one time, processes at one time, the dislocation annular groove 5 of identical size is processed on the inclined-plane 4, when medium flows through this
When a little annular grooves 5, medium has to pass through such route: medium is first got between 1 liang of inclined-plane 4 of spool 2 and valve seat, then again
The annular groove 5 between two inclined-planes 4 is flowed into, in this process, the area that medium flows through is become larger suddenly by small, according to hydromechanical primary
The continuity equation of sharp equation and liquid is exerted, the area that medium passes through increases, and the flow velocity of medium just reduces, and between two inclined-planes 4
There is the annular groove 5 of multiple tracks, so when medium flows to sealing surface 6, by the down speeding procedure of such multiple tracks, the section of the annular groove 5
Shape is semicircle or polygon, can increase the area of flow of media in this way, the reduction of speed effect of medium is more preferable, such medium pair
The influence of sealing surface 6 is just preferably minimized.
The utility model substantially reduces the flow velocity of medium by the annular groove design on spool and valve seat, avoids to sealing surface
It impacts, has the characteristics that economical, reliable；There is good practical value, good economic benefit can be generated after popularization and application,
The structure can be made to be widely used on different valves, avoid damage to the sealing surface of valve, improve the service life of valve.
Although the utility model is disclosed as above with preferred embodiment, so it is not intended to limit the utility model, any
Those skilled in the art, without departing from the spirit and scope of the utility model, when can make a little modification and it is perfect, therefore this
The protection scope of utility model, which is worked as, to be subjected to the definition of the claims.
