Abstract
The invention relates to a high-pressure labyrinth-typed anti-cavitation sleeve valve, which is characterized in that a valve base is provided with a pressure reduction plate which is provided with a pressing plate; the pressure reduction plate is fixed in a valve body by the pressing plate and the valve base; the pressing plate is covered by an upper cover; the upper cover and the valve body are fixedly connected with each other by a bolt; the valve body is internally provided with a valve core component; filler and a filler pressing cover are arranged between the valve core component and the upper cover; the valve core component and the upper cover are sealed by the filler; the pressure reduction plate is a labyrinth-typed pressing plate. The high-pressure labyrinth-typed anti-cavitation sleeve valve has simple, compact and reasonable structure; the movement of the sleeve is completed under the driving of an execution mechanism; the execution mechanism drives the sleeve to move upwards and downwards to control the flux which passing by the labyrinth-typed pressure reduction plate and to change the flux area, thus controlling the flux and pressure of the fluid; owning to the special structure of the labyrinth-typed pressure reduction plate, the pressure of the fluid is greatly reduced after flowing by the pressure reduction plate, the speed energy of the fluid is weakened, the damage on the valve body is avoided, and the vibration and noise coefficient of the valve are reduced.
Description
Technical field
The present invention relates to a kind of high pressure labyrinth type anti-cavitation sleeve valve, specifically be suitable for employed valve in supply and drain water system and the industrial fluids system, belong to the machinery valve industry field.
Background technique
In the existing technology, particularly in industrial fluids power conduit system, valve is primary element of realizing whole system automation control.Its assurance system control safe, instant and effectively, central topmost factor is the adjusting of pressure, speed and the operation of flow control valve, particularly under High Temperature High Pressure, and can not cause the infringement of valve body and system under any operation.It is the problem place that this field domestic demand solves.The common problem that conventional control valve exists under harsh operating mode is:
1, trim is fragile, easily vibration: under harsh operating mode, particularly under the fluid effect of high pressure, high speed, flow control valve very easily produces violent oscillation phenomenon.High-velocity fluid is to the damage that also very easily causes trim of washing away of trim.
2, the generation of air pocket, cavitation phenomenon: when the pressure of fluid drops to below the vapor pressure, just be easy to generate the generation of steam flashing and bubble, the existence of this phenomenon very easily causes damage to trim.
3, operation is subjected to the operating mode restriction: when High Pressure Difference or big flow generation, traditional rotary-type or ball-type control valve has performance constraint to a certain degree.Can produce the generation that cavitation phenomenons also has high noisy.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of high pressure labyrinth type anti-cavitation sleeve valve is provided, fluid is reduced greatly through the pressure behind the decompression board, weakened the speed energy of fluid, avoid the infringement of valve body, reduced the vibration and the noise coefficient of valve.
According to technological scheme provided by the invention, high pressure labyrinth type anti-cavitation sleeve valve comprises valve body, valve seat, loam cake and mangetic core assembly, feature is: on the described valve seat decompression board is housed, pressing plate is housed on the decompression board, and described decompression board is fixed in the valve body by pressing plate and valve seat, and loam cake is housed on the pressing plate, be connected and fixed by bolt between loam cake and the valve body, mangetic core assembly is installed in the valve body, filler and Gland are housed between mangetic core assembly and the loam cake, seal by filler between mangetic core assembly and the loam cake.Described decompression board is the mazy type pressing plate.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Moving of sleeve finished by the driving of actuator; Actuator drives sleeve and moves up and down the flow of controlling by the labyrinth decompression board, changes circulation area; And then the flow and the pressure of the fluid that passes through of control, because the special construction of labyrinth decompression board makes fluid reduce greatly through the pressure behind the decompression board, weakened the speed energy of fluid, avoided the infringement of valve body, reduced the vibration and the noise coefficient of valve.
Description of drawings
Fig. 1 is a structure sectional view of the present invention.
Fig. 2 is the structural representation of labyrinth of the present invention decompression board.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise valve body 1, valve seat 2, decompression board 3, pressing plate 4, loam cake 5, mangetic core assembly 6, filler 7 and Gland 8 etc.
On the valve seat 2 of the present invention decompression board 3 is housed, decompression board 3 is the mazy type pressing plate.Pressing plate 4 is housed on the decompression board 3, described labyrinth decompression board 3 is fixed in the valve body 1 by pressing plate 4 and valve seat 2, loam cake 5 is housed on the pressing plate 4, be connected and fixed by bolt between loam cake 5 and the valve body 1, mangetic core assembly 6 is installed in the valve body 1, filler 7 and Gland 8 are housed between mangetic core assembly 6 and the loam cake 5, seal by filler 7 between mangetic core assembly 6 and the loam cake 5.Mangetic core assembly 6 is welded to form and is lived with lock by valve rod and valve plug, and when actuator drove mangetic core assembly 6 and moves up and down, change had just taken place the circulation area by labyrinth decompression board 3, when mangetic core assembly 6 moves upward, circulation area increases, otherwise circulation area reduces.Because the special construction of labyrinth decompression board, variation has just taken place by the labyrinth with the pressure and the speed energy of pressing plate in fluid.
By as above structure Design, the pressure of the fluid of this valve of flowing through reduces greatly, and speed tends towards stability, and has significantly reduced air pocket cavitation and cavitation phenomenons, and has overcome the phenomenon of vibration, even the fluid of High Pressure Difference is by also without any vibration.
In sum, high pressure labyrinth type anti-cavitation sleeve valve vibrates than flow pressure control, minimizing in the prior art really and all increases on working life.
