Description
Technical field
The utility model relates to a kind of hand-operated direction valve, and referring in particular to a kind of metered flow that is used for the coal mine fully-mechanized mining working hydraulic support is 500L/min plug-in hand-operated direction valve.
Background technology
In the prior art, the structure of hand-operated direction valve is varied, as Chinese patent disclosed " metered flow is the reversal valve of 400L/min " (China, ZL200520003881.9, the day for announcing: on March 28th, 2006), it comprises valve body, operating mechanism, and valve body has working chamber up and down, the last working chamber liquid in-out mouth that communicates with following working chamber two places, last working chamber is identical with following working chamber structure.In the colliery industry, also there is the people reversal valve to be called " control valve ".Reversal valve in the hydraulic support control system, control liquid flow path direction, the different actions such as realizing the hydraulic support lifting, pass, try to stop people from fighting each other, side guard board is stretched receipts, wall supporting is stretched receipts.But the hand-operated direction valve that uses is the accessory assembly type at present, and flow is less, domestic maximum is 400L/min only, because hermetically-sealed construction defective, when under the numerous coal mine in the whole nation, using, the seepage phenomenon occurred, limited by conditions down-hole, can't under coal mine, keep in repair, make to the down-hole maintenance, produce, change and bring many difficulties.
Summary of the invention
It is 500L/min plug-in hand-operated direction valve that the purpose of this utility model is to provide a kind of metered flow that is used for the coal mine fully-mechanized mining working hydraulic support, and its compact conformation is convenient to installation and maintenance, and sealing performance is reliable, and flow is big.
For achieving the above object, the solution that the utility model is taked is: a kind of plug-in hand-operated direction valve, it comprises valve body, operating mechanism, lever is arranged in the operating mechanism, have two identical valve pockets in the valve body and promptly go up working chamber and following working chamber, last working chamber leads to second working hole, following working chamber leads to first working hole, the end of valve body is drilled with inlet and liquid return hole, inlet and liquid return hole communicate with valve pocket, return the liquid valve pad, press nail and push rod to form push rod component, push rod component and time liquid valve flat seal, feed liquor valve and feed liquor valve pad flat seal, joint, spring, the feed liquor valve, the feed liquor valve pad, the valve pad seat ring, tighten the composition one with screw thread on the left of returning liquid valve and spacing middle cover, push rod component, bar cover and valve pocket right side are tightened with trip bolt and are formed one and overlap core assembly, and core assembly is made the as a whole plug connector valve pocket of packing into.
The utility model compact conformation, metered flow are 500L/min.Feed liquor valve and the sealing of feed liquor valve pad, push rod component and time liquid valve flat seal, the hermetically closing more reliable performance.Core assembly is made as a whole plug connector, with the special tool integral body valve pocket of packing into, but integral demounting when needing maintenance, to make things convenient for well servicing under the attendant of colliery.
Description of drawings
Fig. 1 is that the master of present embodiment looks cross-sectional view.
Among the figure: 1, valve body, 2, joint, 3, spring, 4, feed liquor valve, 5, the feed liquor valve pad, 6, the valve pad seat ring, 7, cover in spacing, 8, return the liquid valve, 9, press nail, 10, return the liquid valve pad, 11, trip bolt, 12, push rod, 13, bar cover, 14, lever, 15, operating mechanism, 16, liquid return hole, 17, inlet, 18, first working hole, 19, second working hole.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described again.
Referring to Fig. 1, a kind of plug-in hand-operated direction valve, it comprises valve body 1, operating mechanism 15, lever 14 is arranged in the operating mechanism 15, have two identical valve pockets in the valve body 1 and promptly go up working chamber and following working chamber, last working chamber leads to second working hole 19, following working chamber leads to first working hole 18, the end of valve body 1 is drilled with inlet 17 and liquid return hole 16, inlet 17 and liquid return hole 16 communicate with valve pocket, return liquid valve pad 10, press nail 9 and push rod 12 to form push rod component, push rod component and time liquid valve 8 flat seals, feed liquor valve 4 and feed liquor valve pad 5 flat seals, joint 2, spring 3, feed liquor valve 4, feed liquor valve pad 5, valve pad seat ring 6, return liquid valve 8 and spacing in cover 7 left sides tighten the composition one with screw thread, push rod component, bar cover 13 and spacing in cover 7 right sides tighten with trip bolt 11 and form one and overlap core assembly, core assembly is made the as a whole plug connector valve pocket of packing into.[0009] referring to Fig. 1, its operating principle is: when operating mechanism 15 mediated, the interface that leads to each working chamber communicated with liquid back pipe.Feed liquor valve 4 under the effect of spring 3 with 5 contact seals of feed liquor valve pad; When operating mechanism 15 will descend the push rod 12 of working chamber to depress, going back to liquid valve pad 10 elder generations and returning 8 contact seals of liquid valve in the push rod component, returning the power that liquid valve 8 overcomes spring 3 makes the feed liquor valve separate with the feed liquor valve pad, 4 on joint 2 and feed liquor valve form the feed liquor opening, highly pressurised liquid enters from this mouth, by first working hole 18 to bracket upright post or jack feed flow; When the push rod component in following working chamber is depressed, the push rod component of last working chamber is then under the effect of lever 14, force the liquid valve pad 10 that returns in this chamber to form very big time liquid opening with time liquid valve 8 end faces, bracket upright post or jack return liquid liquid and get back to liquid return hole 16 by second working hole 19, with this realize setting prop, fall post, work such as passing.
Referring to Fig. 1, valve body 1 can be formula on chip or monolithic construction.
Present embodiment is a ZSCH plug-in hand-operated direction valve, and metered flow: 500L/min, operating pressure: 31.5MPa, working media are 5% oil emulsion, 95% neutral water mix emulsion fluid.
