Abstract
The utility model provides a kind of labyrinth valve seat, including valve seat matrix, through with valve chamber among valve seat matrix, support lugn is fixed on valve seat matrix inner wall, support lugn is equipped with labyrinth block, mutually indepedent with several and perforation labyrinth block upper and lower surface labyrinth hole on the block of labyrinth, labyrinth hole is connected to the valve chamber below valve chamber and labyrinth block above the block of labyrinth.The utility model structure is simple, and design rationally, is designed using labyrinth block, labyrinth hole is opened up on the block of labyrinth, can avoid the erosion of medium under High Pressure Difference operating condition, effectively progress multilevel decompression.
Description
Technical field
The utility model relates to valve inner reduction technology field more particularly to a kind of labyrinth valve seats.
Background technique
Valve seat is detachable face component in valve, is used to support spool closed positions, and constitute sealing pair.General valve seat is straight
Diameter is valve maximum flow diameter.Valve needs effectively to be depressured under High Pressure Difference operating condition, reduces medium erosion.It is existing
Valve labyrinth is generally designed on sleeve, and bulk is limited in valve chamber, and multilayer labyrinth can not be designed on sleeve
It is depressured.It is depressured if you need to design multilayer labyrinth, then needs to re-start valve valve chamber design, expanded empty in valve chamber
Between, valve produces and processes cost and difficulty rises.Therefore, it is necessary to be directed to existing valve, otherwise designed one kind can be carried out effectively
The valve seat of decompression.
Utility model content
Technical problem to be solved by the utility model is: the deficiency in order to overcome the prior art, the utility model provides one
Kind structure is simple, and design rationally, is not necessarily to dilatation valve chamber, can be effectively depressured under High Pressure Difference operating condition, reduce medium erosion
Labyrinth valve seat.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of labyrinth valve seat, including valve seat matrix,
Through having valve chamber among the valve seat matrix, support lugn, the support are fixed on the valve seat matrix inner wall
Flange is equipped with labyrinth block, has several mutually indepedent on the labyrinth block and penetrates through the labyrinth hole of labyrinth block upper and lower surface,
The valve chamber below valve chamber and labyrinth block above the labyrinth hole connection labyrinth block.
Further, labyrinth hole is formed by several rectangular-shape through-holes are successively end to end.
Further, support lugn is an integral molding structure with valve seat matrix.
In use, support lugn is set in valve chamber, and places labyrinth block on support lugn, and valve is in High Pressure Difference operating condition
Under, medium will not direct erosion valve seat matrix, but first in labyrinth block surface erosion, and by the labyrinth hole on the block of labyrinth from fan
Valve chamber enters valve chamber below the block of labyrinth above the block of palace.In the process, high-pressure medium labyrinth block surface erosion can removal pressure,
When flowing out below the block of labyrinth, medium is well depressured, will not the valve seat matrix to lower section carry out transition and wash away, effectively carry out
Decompression, avoids influence of the high pressure operating condition to valve seat matrix.
The utility model has the beneficial effects that labyrinth valve seat provided by the utility model, structure is simple, and design rationally, is adopted
It is designed with labyrinth block, labyrinth hole is opened up on the block of labyrinth, can avoid the erosion of medium under High Pressure Difference operating condition, effectively carry out multistage drop
Pressure.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model optimum embodiment.
Fig. 2 is the top view of Fig. 1.
1 in figure, valve seat matrix 2, valve chamber 3, support lugn 4, labyrinth block 5, labyrinth hole.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of labyrinth valve seat as depicted in figs. 1 and 2 is the utility model optimum embodiment, including valve seat matrix 1, institute
Through having valve chamber 2 among the valve seat matrix 1 stated, support lugn 3 is fixed on 1 inner wall of valve seat matrix.Support lugn 3
In actual design, it may be designed as and the integrally formed structure of valve seat matrix 1.
Support lugn 3 is equipped with labyrinth block, has several mutually indepedent on the labyrinth block and above and below perforation labyrinth block
The labyrinth hole 5 on surface, the labyrinth hole 5 are connected to the valve chamber 2 below valve chamber 2 and labyrinth block above the block of labyrinth.If labyrinth hole 5 by
Do a rectangular-shape through-hole successively end to end composition.
The labyrinth valve seat being designed in this way, structure is simple, and design rationally, is designed using labyrinth block, fan is opened up on the block of labyrinth
Palace hole 5 can avoid the erosion of medium under High Pressure Difference operating condition, effectively progress multilevel decompression.
In use, support lugn 3 is set in valve chamber 2, and places labyrinth block on support lugn 3, and valve is in High Pressure Difference
Under operating condition, medium will not direct erosion valve seat matrix 1, but first in labyrinth block surface erosion, and pass through the labyrinth on the block of labyrinth
Hole 5 enters valve chamber 2 below the block of labyrinth from valve chamber 2 above the block of labyrinth.In the process, high-pressure medium labyrinth block surface erosion can
Removal pressure, when flowing out from labyrinth block lower section, medium has carried out good decompression by the bending in labyrinth hole 5, will not be under
The valve seat matrix 1 of side carries out transition and washes away, and is effectively depressured, avoids influence of the high pressure operating condition to valve seat matrix 1.Actually setting
In meter, according to magnitude of pressure differential, the size and number in labyrinth hole 5 is designed, it more can be according to pressure difference, in 1 inner wall of valve seat matrix
Upper multiple labyrinth blocks support lugn 3 and be placed on support lugn 3 of design, further increase the antihypertensive effect of valve seat.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
