Furthermore, a limit stop is fixedly arranged on the guide rail.
Furthermore, the guide rails are four which are uniformly arranged along the inner wall of the balance cavity.
Furthermore, an inclined supporting plate is fixedly arranged between the mounting plate and the guide sleeve.
Beneficial effects of the utility model
A self-operated balance valve with stable operation has the following characteristics:
1. the structure is simple, and the disassembly and the assembly are convenient;
2. manual operation is not needed, and self-balancing can be achieved;
3. the operation is stable and reliable;
4. the internal components are not corroded by the medium, and the service life is long.
Drawings
Fig. 1 is a schematic view of the structure of the present invention;
in the figure, 1, a valve body, 2, a water inlet, 3, a water outlet, 4, a balance cavity, 5, a guide sleeve, 6, a valve cover, 7, a flange, 8, a mounting plate, 9, a limit stop, 10, a guide rail, 11, a spring, 12, a valve block, 13, a valve rod, 14, a sealing groove, 15, a yielding port, 16, a limiting plate and 17 are inclined supporting plates.
Detailed Description
The utility model provides a self-operated balance valve that operates stably, its includes valve body 1, valve rod 13, valve block 12 and valve gap 6, the valve body bottom is equipped with water inlet 2, and the lateral part is equipped with delivery port 3, and upper portion is equipped with balanced chamber 4, balanced chamber is equipped with the mouth 15 of stepping down corresponding with the delivery port, the valve gap passes through flange 7 fixed mounting in the top in balanced chamber, and valve gap easy dismounting, and the part installation in the balanced intracavity of being convenient for.
The lower part of the valve cover is fixedly provided with a guide sleeve 5, and the guide sleeve and the valve cover can be welded or fixedly connected by bolts or integrally formed.
Fixed mounting panel 8 that is equipped with on the uide bushing lower part outer wall, valve rod upper portion is located the uide bushing, and valve rod lower part fixed mounting has limiting plate 16, hangs a plurality of springs 11 of dress between limiting plate and the mounting panel, valve block fixed mounting is in valve rod bottom and the size and the delivery port of valve block and the mouth phase-match of stepping down, let a plurality of seal grooves 14 of having seted up respectively in mouth and delivery port department, seal groove department pressure equipment has a sealing washer (not shown), has a plurality of guide rails 10 along hoop fixed mounting on the balanced intracavity wall, and the edge of limiting plate passes through the slider and is connected with the guide rail.
Furthermore, a limit stop 9 is fixedly mounted on the guide rail, so that the ascending position of the valve block can be limited, the bottom of the valve block is not separated from the position-giving opening all the time, the sealing in the balance cavity is kept, and the spring is prevented from bearing over extrusion.
Furthermore, the guide rails are four which are uniformly arranged along the inner wall of the balance cavity, so that the valve block is more stable and reliable to operate.
Furthermore, an inclined supporting plate 17 is fixedly installed between the installation plate and the guide sleeve, and the stability of the installation plate is guaranteed.
The utility model provides a pair of self-operated balance valve that operates stably, when the water inlet of valve body bottom does not have water inflow or only when little rivers, inside and outside pressure is balanced basically, and the valve piece blocks at the water inlet with step down a mouthful department, the water inlet and step down a mouthful department in airtight state, increases to a certain extent when rivers, and the valve piece upwards moves gradually, and opens the water inlet, rivers flow in from the water inlet, flow from the delivery port. Along with the pressure crescent of inlet water, the valve block upward movement, because valve rod and limiting plate simultaneous upward movement, the slider that works as the limiting plate moves to limit stop department, the bottom of valve block just is in the sealing washer department of stepping down this moment, and upward movement no longer, can guarantee that balanced chamber is in encapsulated situation always, prevent that the medium from getting into balanced intracavity, corrode inside structure, and simple structure, need not manual operation, simultaneously again because valve rod upper portion is located the uide bushing, there are a plurality of guide rails along hoop fixed mounting on the balanced intracavity wall, the edge of limiting plate passes through the slider and is connected with the guide rail, can guarantee the vertical up-and-down motion of valve block, make the operation of valve more reliable and more stable.
To sum up, the utility model discloses a move stable formula of relying on oneself balanced valve who protects, simple structure need not manual operation, moves reliably and the inner member can not receive the medium corrosion.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
