Abstract
The utility model discloses a valve seat with a flow guide groove. A bottom-to-top through hole is formed in the center of the valve seat to form a fluid passage for fluid to flow; the valve seat is characterized in that the inner wall of the through hole is provided with a plurality of flow guide grooves which are sequentially arranged. According to the valve seat, the scouring of the flow of the fluid to the internal structure of a valve can be greatly reduced, the flow speed of the fluid in the valve is reduced, the high Reynolds laminar condition of the fluid can be effectively changed, and the life of the valve is prolonged.
Description
Technical field
The utility model relates to valve mechanism, is specifically related to a kind of valve seat with guiding gutter.
Background technique
Valve is widely used in, in the fluid control devices in the various fields such as oil, chemical industry, metallurgy, weaving, machinery, playing vital effect in whole equipment and system.The unstability that fluid is mobile or under High Pressure Difference, fluid has a strong impact on the working life of valve to the percussion of valve, causes system, equipment to work, and is seriously the generation that may cause catastrophic failure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of valve seat with guiding gutter, for reducing valve inner fluid speed, reduce mobile the washing away valve internal structure of fluid, when valve seat of the present utility model can adapt to, wash away serious grade and lead bad working environments, guiding gutter can effectively change the high renaut's layer stream mode of fluid, can enter in advance turbulent condition, make under same pressure reduction other valve seat construction relatively, can effectively extend life of valve
The technological scheme that the utility model addresses the above problem is:
The through hole that the valve seat ，Qi center of guiding gutter is up/down perforation forms a fluid passage of passing through for fluid, it is characterized in that: on the inwall of described through hole, be formed with several tactic guiding gutters.
Further, the technical solution of the utility model can also be:
Periphery along the hole wall on the top of described through hole is provided with guiding gutter.
The oblique downward-extension of described guiding gutter.
The sectional shape of the recess part of described guiding gutter is triangle.
Valve seat with guiding gutter of the present utility model can greatly reduce fluid and flow to the washing away of valve internal structure, and reduces valve inner fluid speed, can effectively change the high renaut's layer stream mode of fluid, extends life of valve.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the valve seat with guiding gutter of the present utility model.
Fig. 2 is the configuration diagram of overlooking of the valve seat with guiding gutter of the present utility model.
Description of reference numerals
1, valve seat 2, fluid passage 3, guiding gutter
Specific embodiments
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The through hole that is up/down perforation with the valve seat 1 ，Qi center of guiding gutter of the present utility model as shown in Figure 1-2 forms the fluid passage 2 of passing through for fluid, is formed with several tactic guiding gutters 3 on the inwall of through hole.
In this example, guiding gutter is along the periphery setting of the hole wall on the top of through hole.
In this example, due to fluid passage be shaped as top open shape obliquely, the top of the hole wall of through hole is true dip direction wide at the top and narrow at the bottom, thus the bearing of trend of guiding gutter and the bearing of trend of hole wall consistent, be oblique downward-extension.
In this example, the sectional shape of the recess part of guiding gutter is triangle.
When the flow through fluid passage at valve seat center of the fluid of high-speed motion, fluid becomes washing away of fluid and each guiding gutter for washing away of valve seat, the existence of guiding gutter can reduce rate of flow of fluid greatly, alleviate mobile the washing away valve internal structure of fluid, thereby effectively change the high renaut's layer stream mode of fluid, make fluid enter in advance turbulent condition, extend life of valve.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong to the protection domain of technical solutions of the utility model.
Claims (4)
1. the through hole that is up/down perforation with the valve seat ，Qi center of guiding gutter forms a fluid passage of passing through for fluid, it is characterized in that: on the inwall of described through hole, be formed with several tactic guiding gutters.
