Abstract
The utility model relates to a plug- in type hand-operated direction valve which comprises a valve body and a manipulating mechanism, wherein a lever is arranged in the manipulating mechanism; two identical valve chambers (namely an upper work chamber and a lower work chamber) are arranged in the valve body; the upper work chamber is communicated with a second work port, the lower work chamber is communicated with a first work port; and a liquid inlet and a liquid outlet are arranged on the plane surface of the valve body, and the liquid inlet and the liquid outlet are communicated with the valve chamber. An ejector assembly consists of a liquid returning valve pad, a press button and an ejector rod, and the ejector assemblies are in a plane surface seal with a sleeve valve. The sleeve valve is in a plane surface seal with a liquid inlet valve pad. A joint, a spring, the sleeve valve, the liquid inlet valve pad and the left side of the valve chamber are tightened through screws to form a whole body. The ejector assembly, an ejector sleeve and the right side of the valve chamber are tightened through tightening screws to form a set of valve plug assemblies which is taken as an integral connector to be inserted into the valve chamber. The plug-in type hand-operated direction valve is used as a hydraulic support of the full-mechanized mining face for coal mine.
Description
Technical field
The utility model relates to a kind of hand-operated direction valve, refers in particular to a kind of plug-in hand-operated direction valve that is used for the coal mine fully-mechanized mining working hydraulic support.
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, because the hermetically-sealed construction defective, when under the numerous coal mine in the whole nation, using, the seepage phenomenon has appearred, 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
The purpose of this utility model is to provide a kind of plug-in hand-operated direction valve, and its compact conformation is convenient to installation and maintenance, and sealing performance is reliable, and flow is big, is used for the coal mine fully-mechanized mining working hydraulic support.
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, having two identical valve pockets in the valve body is working chamber and following working chamber, last working chamber leads to second working hole, following working chamber leads to first working hole, the place, plane of valve body is drilled with inlet and liquid outlet, inlet and liquid outlet communicate with valve pocket, return the liquid valve pad, press nail and push rod to form push rod component, push rod component and tube valve flat seal, tube valve and feed liquor valve pad flat seal, joint, spring, the tube valve, the composition one is tightened with screw thread in feed liquor valve pad and valve pocket left side, 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.Tube valve and the sealing of feed liquor valve pad, push rod component and tube 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, tube valve, 5, the feed liquor valve pad, 6, valve pocket, 7, press nail, 8, return the liquid valve pad, 9, trip bolt, 10, push rod, 11, the bar cover, 12, lever, 13, operating mechanism, 14, liquid outlet, 15, inlet, 16, first working hole, 17, 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 13, lever 12 is arranged in the operating mechanism 13, 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 17, following working chamber leads to first working hole 16, the place, plane of valve body 1 is drilled with inlet 15 and liquid outlet 14, inlet 15 and liquid outlet 14 communicate with valve pocket, return liquid valve pad 8, press nail 7 and push rod 10 to form push rod component, push rod component and tube valve 4 flat seals, tube valve 4 and feed liquor valve pad 5 flat seals, joint 2, spring 3, tube valve 4, the composition one is tightened with screw thread in feed liquor valve pad 5 and valve pocket 6 left sides, push rod component, bar cover 11 and valve pocket 6 right sides are tightened with trip bolt 9 and are formed one and overlap core assembly, and core assembly is made the as a whole plug connector valve pocket of packing into.
Referring to Fig. 1, valve body 1 can be formula on chip or monolithic construction.
Present embodiment is a FHSCl plug-in hand-operated direction valve, and metered flow: 400L/min, operating pressure: 31.5MPa, working media are 5% oil emulsion, 95% neutral water mix emulsion fluid.
Referring to Fig. 1, its operating principle is: when operating mechanism 13 mediated, the interface that leads to each working chamber communicated with liquid back pipe.The tube valve 4 under the effect of spring 3 with 5 contact seals of feed liquor valve pad; When operating mechanism 13 will descend the push rod 10 of working chamber to depress, time liquid valve pad 8 elder generations in the push rod component and 4 contact seals of tube valve, joint 2 and 4 on valve of tube form the feed liquor opening, and highly pressurised liquid enters from this mouth, by first working hole 16 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 12, force the liquid valve pad 8 that returns in this chamber to form very big time liquid opening with tube valve 4 end faces, bracket upright post or jack return liquid liquid and get back to liquid outlet 14 by second working hole 17, with this realize setting prop, fall post, work such as passing.
