Abstract
The utility model discloses a high flow high pressure backwash valve, which comprises a valve body, a valve core and a valve core, wherein the inner portion of the valve body is provided with the valve core, the valve body on the outer end of the valve core is fixedly provided with the valve cover through screws, the middle portion of the valve core is provided with a hydraulic control mouth, and a sealing ring is arranged between the valve core and the inner wall of the valve body. The high flow high pressure backwash valve has the beneficial effects that the high flow high pressure backwash valve has the function of backwashing a filter core, is beneficial for achieving automatic control of backwash of emulsified liquid, does not need to artificially close to a high voltage device, reduces the hazard ratio, and connecting the control mouth through an oil pipe. The high flow high voltage backwash valve has simple structure and steady operation, can use bigger pressure grade, rapidly opens, and is suitable for high flow liquid to pass through the valve.
Description
Technical field
The utility model relates to a kind of backwash valve, relates in particular to a kind of big-flow high-pressure backwash valve.
Background technique
The coal mine lower support frame in use needs to filter with emulsified liquid, and filter core needs to pull down cleaning after stopping up, and this has a strong impact on working efficiency.Present high pressure back-flushing filtering device generally adopts the reverse cleaning valve of manual similar spheroidal stop valve structure, when filtrating equipment needs oppositely to clean, make liquid road conversion high pressure liquid and realize reverse flow cleaning filter core by manually pulling handle, but this structure is because handling time is long, in commutation process, easily emulsion system is produced the liquid resistance and supercharging suddenly produces the influence that pressure falls, be unfavorable for realizing the automatic control of high pressure back-flushing filtering device again.
The model utility content
At above defective, the purpose of this utility model provides a kind of simple in structure, stable operation, help realizing that emulsion backwash controls, can improve the big-flow high-pressure backwash valve of filter precision automatically, to realize the function of back flush filter core.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of big-flow high-pressure backwash valve, comprise valve body, valve gap and spool, described valve inner is provided with spool, by screw valve gap is installed on the outer end valve body of spool, the hydraulic control mouth is offered at described valve gap middle part, be provided with seal ring between described spool and the valve interior wall, valve body one side is provided with sewage draining exit.
The beneficial effect of big-flow high-pressure backwash valve described in the utility model is: have the function of back flush filter core, help realizing the automatic control of emulsion backwash; Need not artificial close high-pressure installation, reduced dangerous probability, the control mouth links to each other by oil pipe; Simple in structure, stable operation, can use big pressure rating; Opening is quick, and suitable big fluid flow is by this valve.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the structural representation of the described big-flow high-pressure backwash valve of the utility model embodiment;
Fig. 2 is the user mode schematic representation of the described big-flow high-pressure backwash valve of the utility model embodiment.
Among the figure:
1, valve body; 2, valve gap; 3, screw; 4, hydraulic control mouth; 5, spool; 6, seal ring; 7, sewage draining exit; 8, valve seal structure; 9, emulsified liquid inlet; 10, emulsified liquid outlet.
Embodiment
Shown in Fig. 1-2, big-flow high-pressure backwash valve described in the utility model comprises valve body 1, valve gap 2 and spool 5, and described valve body 1 inside is provided with spool 5, by screw 3 fixed installation valve gaps 2, hydraulic control mouth 4 is offered at these valve gap 2 middle parts on the outer end valve body 1 of spool 5; Be provided with seal ring 6 between described spool 5 and valve body 1 inwall, valve body 1 one sides are provided with sewage draining exit 7, other side in valve body 1 inner chamber is offered emulsified liquid inlet 9 and emulsified liquid outlet 10 respectively, is equipped with valve seal structure 8 between described sewage draining exit 7, emulsified liquid inlet 9, emulsified liquid outlet 10 and the valve body 1.During use, can adopt two valves that one group of filtrating equipment is controlled, high-pressure emulsion enters this valve through inlet under normal conditions, back down spool 5 laggard inlet/outlets, the passage that cuts off outlet and sewage draining exit 7 after spool 5 displacements, this moment, high-pressure emulsion entered the clearance filter outside by outlet, the pure emulsified liquid after the emulsified liquid of process clearance filter promptly filters, and the filter precision of its pure degree and filter core is relevant; After filter core stops up through working after a while, the liquid resistance increases, the pressurization to hydraulic control mouth 4 is realized at the interval that enters by time set control liquid, spool 5 moved right under the promotion of seal ring 6 and cut off import and outlet this moment, connect outlet and sewage draining exit 7, make the outer pollutant recoil of filter core to sewage draining exit, by the function that can realize the back flush filter core that is used alternatingly of two backwash valves.
