Description
Technical field
The present invention relates to a kind of valve part, be specifically related to the valve member of a kind of improved structure.
Background technology
For the valve of fluid control systems, used each from simplest stop valve to extremely complex robot control system(RCS)
Planting valve, its kind and specification are the most various.Valve can be used for controlling sky gas and water, steam, various Korrosionsmedium, mud, oil
The flowing of all kinds fluids such as product, liquid metal and radiating medium.
Valve is during long-term use, and when spool is closed, spool contacts flow velocity at front sealing surface and drastically increases with valve seat
Greatly, it is easy to the phenomenon such as flash distillation, cavitation occurs, spool is damaged with valve seat and sealing ring, cause valve seal to drop
Low, and affect its service life.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides the valve member of a kind of improved structure, and this valve member can
Improve the sealing of valve, be prevented effectively from the sealing that valve causes by erosion medium resistance during life-time service and reduce.
The present invention is achieved through the following technical solutions:
The valve member of improved structure, including valve body, valve rod, flap and sealing ring, is provided with valve seat, described sealing in described valve body
Circle is fixed on valve seat, and sealing ring ringwise, is provided with an annular groove at sealing ring upper surface, and described flap is by antifriction metal (AFM)
Making, flap upper end is connected with valve rod, and flap bottom surface is provided with an annular boss mated with sealing ring annular groove, flap with
Valve seat is fitted tightly by annular boss and the sealing ring with annular groove, and described sealing ring is additionally provided with some connection valve bodies
Water inlet end and the throttling through hole of water side.
Described flap is made up of hard alloy, and described sealing ring is made up of politef.Hard alloy has the highest
Intensity, it is possible to the impact of fluid resistant, poppet ruggedness.Sealing ring uses corrosion resistant politef, it is to avoid seal
Circle being corroded property dielectric corrosion, increases the scope of application of this valve member.
Described throttling through hole cross section is circular or rectangle.
The present invention compared with prior art, has such advantages as and beneficial effect:
(1) by increasing throttling through hole in sealing ring, when valve will be closed, it is possible to weaken fluid media (medium) to flap and valve
The impact of seat, it is to avoid owing to long-term erosion effect damages flap or valve seat, affect the use of valve；
(2) present invention is by arranging annular boss on flap, arranges annular groove, utilize annular boss and ring on sealing ring
The cooperation of connected in star, substantially increases the sealing of valve, even if after valve employs for a long time, still ensure that valve
The compactness that lobe coordinates with valve base chamber.

Embodiment
As shown in Figure 1, 2, the valve member of improved structure, including valve body 1, valve rod 2, flap 3 and sealing ring 4, described valve
Being provided with valve seat 5 in body 1, described sealing ring 4 is fixed on valve seat 5, and sealing ring 4 ringwise, is provided with one at sealing ring 4 upper surface
Annular groove 41, described flap 3 is made up of antifriction metal (AFM), and flap 3 upper end is connected with valve rod 2, and flap 3 bottom surface is provided with one with close
The annular boss 31 of seal 4 annular groove 41 coupling, flap 3 by annular boss 31 and has annular groove 41 with valve seat 5
Sealing ring 4 fits tightly, and described sealing ring 4 is additionally provided with the throttling through hole of some connection valve body 1 water inlet ends 11 and water side 12
42。
Described flap 3 is made up of hard alloy, and described sealing ring 4 is made up of politef.
Described throttling through hole 42 cross section is circular or rectangle.
When the valve member of the present invention uses, rotation valve rod 2, and drive flap 3 to move down, the annular bottom flap 3
In the annular groove 41 of boss 31 progressively embedding sealing circle 4, make flap 3 fit with sealing ring 4, strengthen flap 3 and paste with sealing ring 4
The compactness closed, improves valve seal, and when flap 3 progressively contacts with sealing ring 4, the medium of transmission is in flap 3 and sealing
Flow velocity in the gap of circle 4 composition increases, and certain media flows through from throttling through hole 42 simultaneously, substantially reduces fluid media (medium) to valve
Lobe 3 and the impact of valve seat 5, flap 3 and the final tight closure of sealing ring 4, throttling through hole 42 closes the most under stress, and valve is complete
Close, improve valve seal, weaken fluid to flap 3 and the erosion of valve seat 5, effectively extend the use longevity of valve
Life.
Above-described detailed description of the invention, has been carried out the purpose of the present invention, technical scheme and beneficial effect further
Describe in detail, be it should be understood that the detailed description of the invention that the foregoing is only the present invention, be not intended to limit the present invention
Protection domain, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, all should comprise
Within protection scope of the present invention.
