Abstract
The utility model provides a hydraulic control valve which comprises a main valve body (1), a left body valve element (4), a right body valve element (2), a sleeve type main valve body diaphragm (3) and a pilot valve. The sleeve type main valve body diaphragm (3) is installed into a main valve diaphragm cavity in the main valve body (1), the left body valve element (4) and the right body valve element (2) are installed into the main valve body (1), the left body valve element (4) and the right body valve element (2) are located on the two sides of the sleeve type main valve body diaphragm (3) respectively, and the pilot valve is installed above the main valve body (1). The hydraulic control valve can achieve large flow capacity under small pressure losses, stability of pressure of a pipeline system is achieved, the phenomenon of air pockets or air bubbles is not generated, and the hydraulic control valve provides accurate pressure control for being adapted to multiple purposes.
Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of hydraulic control valve.
Background technique
The hydraulic control valve that prior art provides is due to the reason that is structure design itself, therefore in the process of using, can't prevent the generation of air pocket, thereby in use, when particularly using as reduction valve, the mobile phenomenon that causes producing air pocket due to special finally makes the pressure of pipe-line system fluctuate to some extent, and the effect of decompression can not reach the optimum state.
The model utility content
The utility model provides a kind of hydraulic control valve, great through-current capability under lower crushing, and can provide accurately pressure to control to adapt to multiple use.
To achieve these goals, the utility model provides following technological scheme:
A kind of hydraulic control valve, it comprises: main valve body 1, left body spool 4, right body spool 2, sleeve type main valve body barrier film 3 and pilot valve, wherein: described telescopic main valve body barrier film 3 is packed on main valve diaphragm cavity in main valve body 1, described left body spool 4 and right body spool 2 are all packed in described main valve body 1, and described left body spool 4 and right body spool 2 lay respectively at the both sides of described sleeve type main valve body barrier film 3, and described pilot valve is installed in the top of described main valve body 1.
Preferably, described left body spool 4, right body spool 2 are the multi-disc cell structure.
By implementing above technological scheme, have following technique effect: the hydraulic control valve that the utility model provides, great through-current capability under lower crushing realizes the stability of pipe-line system pressure, do not produce air pocket or bubble phenomenon, and can provide accurately pressure to control to adapt to multiple use.
Description of drawings
Fig. 1 provides the sectional view of hydraulic control valve for the utility model embodiment.
Embodiment
In order better to understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
The utility model embodiment provides a kind of hydraulic control valve, it comprises: main valve body 1, left body spool 4, right body spool 2, sleeve type main valve body barrier film 3 and pilot valve 5, wherein: described telescopic main valve body barrier film 3 is packed on main valve diaphragm cavity in main valve body 1, described left body spool 4 and right body spool 2 are all packed in described main valve body 1, and described left body spool 4 and right body spool 2 lay respectively at the both sides of described sleeve type main valve body barrier film 3, and described pilot valve is installed in the top of described main valve body 1.
This hydraulic control valve that assembles is installed in pipe-line system, utilizes the annular knurl type spring pressure on pilot valve 5 tops to adjust outer tube and the inside spring is carried out the setting of pressure, can realize that hydraulic control valve can realize the function of different valves.
When using as reduction valve: under lower crushing, can reach great through-current capability, and the hydraulic control valve that can provide pressure accurately to control the to satisfy difference in functionality requirement of using.Safety reliability and the stability of whole pipe-line system have finally been improved.
When as let out/when holding valve uses: because this hydraulic control valve can carry out pressure release slowly within a certain specific time, pressure is regulated sensitiveer, can be because of the setting cracking pressure of Decompression valves not little and produce misoperation, because this hydraulic control valve in use, make pipeline be in milder working state always, should not be subjected to the pipeline pressure surge and affect this function.Moreover add the seal ring of sleeve type main valve body barrier film, and when using as holding valve, hold and press effect better, in holding the scope of pressure, can easily freely regulate easily pressure.
When using as multifunctional water pump control valve: the structural design that has anti-cavitation due to the valve of this hydraulic control valve, in the moment of pump startup, can produce certain impact of water hammer phenomenon, when this hydraulic control valve of current process, can effectively control water hammer, and telescopic main valve body barrier film reaches the opening and closing action of 20000 times, has effectively guaranteed the working life of this hydraulic control valve valve, possesses simultaneously other functions such as speed is closed, Slow Close.
Concrete, when the reduction valve outlet pressure during greater than setting pressure, the water in this reduction valve outlet port enters in the diaphragm cavity 6 of pilot valve by the water hole on this hydraulic control valve, under the effect of water pressure, move on the sliding spring seat of pilot valve, thereby the spool that drives pilot valve moves up, in the process of moving on the spool of pilot valve, the steel ball of spool both sides is moved to both sides, reduce the flow area in water hole by the shutoff of the pilot valve cartridge type barrier film on the diaphragm cavity 6 of pilot valve.During water injection hole flow area before the flow area in water hole is less than main valve body, the injection amount of cover main valve diaphragm cavity 7 interior water will be greater than water-outlet quantity, it is large that main valve diaphragm cavity 7 becomes under the effect of hydraulic pressure gradually, thereby the flow area of main valve body is reduced, and the pressure of reduction valve outlet simultaneously reduces thereupon.Along with reducing gradually of outlet pressure, the spool of pilot valve moves down under the elastic force of spring, and steel ball also will be to the spool side shifting, and the flow area in water hole increases along with the movement of steel ball.When the flow area in water hole was increased to the flow area that equals the main valve body water injection hole, in the main valve diaphragm cavity, injection amount and the discharge of water reached a state of equilibrium, and this moment, reduction valve was steadily opened, and outlet pressure will remain setting value.What adopt due to left and right spool is the project organization of multi-disc grid, under the main valve body opening state, when pipe-line system is flowed through this hydraulic control valve, can not produce the phenomenon of air pocket.
Above a kind of hydraulic control valve that the utility model embodiment is provided is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
