Abstract
The invention discloses an inserted medium flow upright post hydraulic control one-way valve suitable for upright post control of a medium bracket. The one-way valve comprises a joint, a valve body, a piston, a piston reset small spring and an inserted hydraulic valve core assembly. A valve seat is arranged in the inserted hydraulic valve core assembly, a valve core is arranged in the valve seat, the valve core is inserted into the valve seat and extends out, a spring with compaction effect is arranged inside the valve core, the other end of the spring is connected with a valve sleeve with a safety valve interface, and the valve sleeve and the valve seat are connected into a whole through screw threads. The one-way valve has simple structure, high system integration, strong reliability and long service life, and is easily installed and maintained; and the upright post hydraulic control one-way valve is repaired by directly changing the inserted hydraulic valve core assembly, so the one-way valve is simple, convenient and reliable.
Description
Technical field
The present invention relates to the one way valve field, be specially flow column hydraulic control one-way valve in a kind of plug-in.
Background technology
The column hydraulic control one-way valve, core control element as the lifting of coal mine fully-mechanized mining hydraulic support control column, in coal mine fully-mechanized mining uses, traditional hydraulic control one-way valve adopts the supporting valve fishplate bar of hydraulic control one-way valve to be installed in the column cavity of resorption and uses, it is big to take up room, the line arrangement complex structure, and traditional hydraulic control one-way valve flow is little, sealing surface adopts material sealings such as valve pad or polyformaldehyde, have tiny cinder unavoidably on the coal mine work area or other foreign matters enter 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, and 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 flow column hydraulic control one-way valve in a kind of plug-in, with the taking up space of the column hydraulic control one-way valve that solves prior art, application life with adaptive capacity is low and the problem of maintenance difficult.
In order to achieve the above object, the technical solution adopted in the present invention is:
Flow column hydraulic control one-way valve in a kind of plug-in, include the plate surface sealed valve body, in the described valve body valve pocket is arranged, also be provided with a plurality of advancing of being communicated with valve pocket in the valve body, liquid outlet, it is characterized in that: have the valve pocket of band relief valve connection to be installed in the valve pocket from valve pocket one end, also have joint to be installed in the valve pocket from the valve pocket other end, also be provided with valve seat in the described valve pocket, described valve seat and valve pocket screw togather and are one, also be provided with piston in the valve pocket between valve seat and the joint, there is spool to be slidingly mounted in the valve seat, described spool one end passes valve seat and points to described piston, the spool other end points to described valve pocket, and is connected with spring between the spool other end and the valve pocket, also is provided with between described piston and the valve seat to be enclosed within the little spring that spool passes the valve seat part outside.
Flow column hydraulic control one-way valve in described a kind of plug-in is characterized in that: described spool and valve seat constitute metal hard-sealing.
The present invention is simple in structure, level of integrated system is high, good reliability, long service life, is easy to installation and maintenance, directly repairs this column hydraulic control one-way valve by changing plug-in hydraulic valve core assembly, and is simple and convenient reliable.
Description of drawings
Fig. 1 is the structure diagram of this hydraulic control one-way valve.
The specific embodiment
As shown in Figure 1.Form of structure of the present invention is fit to the column control of medium-sized support, it comprise joint 1, compact conformation plate surface sealed valve body 2, start to control piston 3, the piston 3 of making usefulness reset little spring 4 and plug-in hydraulic valve core assembly.The valve seat 5 that metal material is arranged in the plug-in hydraulic valve core assembly, there is the spool 6 that forms metal hard-sealing with it valve seat 5 inside, spool 6 inserts valve seat 5 and stretches out, there has been the spring 7 of pressuring action spool 6 inboards, the other end of spring 7 is connected the valve pocket 8 that has relief valve connection, and valve pocket 8 and valve seat 5 are by the integrator that is threaded.The present invention is simple in structure, level of integrated system is high, good reliability, long service life, is easy to installation and maintenance, directly repairs this column hydraulic control one-way valve by changing plug-in hydraulic valve core assembly, and is simple and convenient reliable.
Two working chamber structures are identical, its operating principle is as follows: the connected mode of this column hydraulic control one-way valve is: the A working hole shown in the figure dotted line 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 receive adjacent column hydraulic control one-way valve PB interface realization Synchronization Control equally and fall column, and B interface connects the column epicoele.The C mouth connects pressure meter or pressure sensor, and other end C ' adds stifled or connects other work sap cavities.
When operating mode need be controlled column and rises, reversal valve connects the work sap cavity of PA interface and opens feed flow, high-pressure work liquid enters the PA mouth, open spool, working solution enters the back and enters the column cavity of resorption by A flat seal mouth, column is risen, and when the PA end stopped feed flow, big small valve core formed the metal hard-sealing collateral with the feed liquor valve pocket and holds the working solution of column cavity of resorption and stablize constant 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, holding a high-pressure work liquid part that enters to enter the column epicoele by the B mouth from PB descends column, another part makes piston motion push spool earlier open to carry out off-load and make column cavity of resorption liquid flow into the liquid back pipe road by PA, reach the stable post that falls, when PB end working solution stopped feed flow, piston resetted under the little spring effect, and spool resets under spring action and makes column keep steady working condition.
Because hydraulic package of the present invention adopts the metal hard-sealing structure, improved the application life and the adaptive capacity of hydraulic control one-way valve greatly, the plug-in structure makes maintenance more convenient.
