Abstract
The invention discloses a high-flow hydraulic control one-way valve, which comprises a valve body and a valve bush, wherein the valve bush is in threaded connection with the interior of the valve body of a plate-like structure, a big spring is arranged in the valve bush, and a valve core is matched with a valve seat under the pressure of the big spring to form metallic loop line seal; and the valve seat is in threaded connection with the valve bush, springs are arranged inside the valve seat, an ejection rod is arranged between the springs, one end of the ejection rod is limited in the valve seat, the other end of the ejection rod is fixed on a piston by screw threads, and the other end of the valve body is in threaded connection with a joint. The hydraulic control one-way valve is high in integration level, strong in reliability, long in service life and easy in installation and maintenance; and the upright post hydraulic control one-way valve is repaired directly, simply, conveniently and reliably by changing a plug-in hydraulic assembly.
Description
Technical field
The present invention relates to a kind of hydraulic control one-way valve, a kind of specifically big flow hydraulic control one-way valve.
Background technology
Since coal mine fully-mechanized mining begins, because the difference of various coal mining environment has had stricter requirement to hydraulic support and supporting equipment.The hydraulic support technology is got up towards high-end fast development, and support has been broken through 7 meters, and the column cylinder diameter also surpasses 0.5 meter, and so large-scale support presses for the hydraulic control one-way valve of the big dependable performance of flow and controls up-down.We are through independent development, have released that flow is big, long service life, column hydraulic control one-way valve easy to maintenance, and it has adopted the plug-in hard sealing structure; The operating mode that can adapt to high pressure, big flow; Each sealing contact surface all adopts metal loop wire hard sealing structure simultaneously, and prolong application life greatly, and this cover core assembly is through the integrator that is threaded in addition; Realize the plug-in structure, keep in repair efficient and convenient.At present, domestic column control pilot operated valve device flow is little, during off-load hydraulic shock big, all can reduce each component and the bulk life time of valve; Sealing surface adopts material sealings such as valve pad or polyformaldehyde, has tiny cinder or other foreign matters on the coal mine work area unavoidably and gets in the hydraulic valve, when the pilot operated valve device opening and closing; Have impurity and be squeezed on the compressive seal, cause leakage, string liquid, adaptive capacity and application life are all not ideal enough; Traditional in addition valve group is combined by a lot of structural members; Change seal and will dismantle a lot of parts, the very inconvenience in the down-hole, a lot of problems are perplexing the operate as normal production of underground hydraulic support frame.
Summary of the invention
The purpose of this invention is to provide a kind of big flow hydraulic control one-way valve,, application life high and adaptive capacity is low and the problem of maintenance difficult with the hydraulic shock of the column hydraulic control one-way valve that solves prior art.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of big flow hydraulic control one-way valve includes valve body, valve pocket, and said valve pocket is threaded in the valve body of plank frame, is provided with big spring in the valve pocket, and spool is cooperated with valve seat by big spring pressure and forms the metal ring linear sealing; Said valve seat is threaded on the valve pocket, and there is spring the valve seat inboard, and push rod is arranged between the spring, and push rod one end is spacing in valve seat inside, and push rod other end screw thread is fixed on the piston, the valve body other end joint that has been threaded.
Said valve core cavity is sealed into the metal loop wire and seals firmly.
Level of integrated system height of the present invention, good reliability, long service life are easy to installation and maintenance, directly repair this column hydraulic control one-way valve through changing the plug-in hydraulic package, and be simple and convenient reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
With reference to Fig. 1; A kind of big flow hydraulic control one-way valve includes valve body 1, valve pocket 2, it is characterized in that: said valve pocket 2 is threaded in the valve body 1 of plank frame; Be provided with big spring 3 in the valve pocket 2, spool 4 is cooperated with valve seat 5 by big spring 3 pressure and forms the metal ring linear sealing; Said valve seat 5 is threaded on the valve pocket 2, and there is spring 6 valve seat 5 inboards, and push rod 7 is arranged between the spring 6, and push rod 7 one ends are inner spacing at valve seat 5, and push rod 7 other end screw threads are fixed on the piston 8, valve body 1 other end joint 9 that has been threaded.
A ' working hole as shown in the figure passes through four bolt flat seals on column cavity of resorption interface; The PA mouth connects reversal valve work sap cavity; PA ' can receive and realize on the adjacent column hydraulic control one-way valve PA interface that Synchronization Control rises column; The relative work sap cavity of reversal valve that the PB termination is corresponding with PA, PB ' can be received adjacent column hydraulic control one-way valve PB interface realization Synchronization Control equally and fall column, and B ' interface connects the column epicoele.The A mouth connects pressure meter or pressure sensor, and the other end adds stifled or connects other work sap cavities, and A1 can connect safety valve as required or add stifled.
When operating mode need be controlled column and rises; Reversal valve connects the work sap cavity of PA interface and opens feed flow, and high-pressure work liquid gets into the PA mouth, opens large and small spool; Working solution gets into the back and gets into the column cavity of resorption through A ' flat seal mouth; Column is risen, and when the PA end stopped feed flow, spool was stablized constant with the working solution that valve seat formation metal hard-sealing collateral is held the column cavity of resorption under the pressure of back-moving spring.When operating mode need be controlled column and falls; Reversal valve connects the work sap cavity of PB interface and opens feed flow, and a high-pressure work liquid part that gets into from PB end descends column through B ' mouth entering column epicoele, and another part makes piston promote push rod and opens spool and make column cavity of resorption liquid through PA inflow liquid back pipe road; Reach the stable post that falls; When PB end working solution stopped feed flow, valve rod resetted, and valve core reset makes column keep steady working condition.
