The aim of the utility model is to combine hydraulic pilot control with manual direct control. The utility model comprises an operating mechanism, a valve body, fluid return valve cores, fluid return valve sleeves, guide sleeves, push rods, valve seats, fluid inlet valve cores, fluid inlet valve sleeves, springs, pressure regulating bolts, pressure regulating thread sleeves, thread plugs and sealing pieces, wherein the operating mechanism comprises a cam and a pressing block, and two sets of identical fluid return valve cores are arranged in the valve body, fluid return valve sleeves, guide sleeves, push rods, valve seats, fluid inlet valve cores, fluid inlet valve sleeves, springs, pressure regulating bolts and pressure regulating thread sleeves; both sides of the valve body are respectively provided with a working fluid outlet and a guide control fluid inlet, and the middle part of the valve body is provided with a pump fluid inlet and a fluid return port.
Description
Technical field
The utility model relates to a kind of Hydraulic Elements that are used to control hydraulic support.
Background technology
Existing hydraulic support reversal valve has two classes, and a class is single frame hand-operated direction valve, is made up of multi-disc, many handles, and its weak point is that advancing velocity is slow, and labour intensity is big.Another kind of is electrohydraulic control system, mainly is from external introduction, and its weak point is a relatively difficulty of assembling test, on average has higher requirements for support hydraulic system, environment on coalface and operation and management of water.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, provides a kind of with hydraulic pilot control and the manually direct manual duplex reversal valve of hydraulic control that combines of controlling.
The utility model includes operating mechanism, valve body, back fluid spool, liquid return valve jacket, fairlead, push rod, valve seat, feed liquor spool, feed liquor valve pocket, spring, regulator bolts, pressure regulation swivel nut, screw plug and seal.Operating mechanism includes cam, briquetting; Identical back fluid spool, liquid return valve jacket, fairlead, push rod, valve seat, feed liquor spool, feed liquor valve pocket, spring, screw plug, regulator bolts and the pressure regulation swivel nut of two covers is housed in the valve body; The valve body both sides are respectively equipped with the working solution outlet and the guide controls the liquid inlet, and the valve body middle part is provided with pump liquid inlet and liquid return hole.
The utility model is applicable in comprehensive mechanical coal mining work plane control hydraulic support fast moving and support.The utility model has been concentrated the advantage of single frame hand-operated direction valve and electrohydraulic control system, can adopt this direct control, also can realize the hydraulic support Long-distance Control, and two supports are finished composite move in proper order, have improved advancing velocity.The utility model is simple in structure, easy to use, and easy to use and management does not have specific (special) requirements for support hydraulic system, environment on coalface and operator quality.
Description of drawings
Fig. 1 is the utility model structural representation,
Among the figure: 1, operating mechanism, 2, back fluid spool, 3, the feed liquor spool, 4, valve body, 5, liquid return valve jacket, 6, fairlead, 7, push rod, 8, valve seat, 9, the feed liquor valve pocket, 10 pads, 11, pressure regulation swivel nut, 12, spring shim, 13, regulator bolts, 14, screw plug, 15, spring.
The specific embodiment
Valve body 4 both sides are respectively equipped with working solution outlet A, A ' and the guide controls liquid inlet B, B ', the valve body middle part is provided with pump liquid inlet P and liquid return hole O.
Needs according to the support action, the utility model of respective numbers is cascaded, P mouth, O mouth join with pumping plant feed flow pipeline and liquid back pipe road respectively, A mouth, A ' mouth are connected with support operating cylinder two working chambers respectively, and B mouth, B ' mouth are connected with adjacent stent hydraulic control pilot valve working hole respectively.
Manually directly control: move handle, liquid return hole O is closed in back fluid spool 2 compressions that briquetting will a corresponding side, promotes push rod 7 and backs down feed liquor spool 3, and spring 15 is compressed, and pump liquid is entered by the P mouth, through valve seat 8, from outlet A (A ') outflow.Behind the end of operation handle is moved back to the centre position, feed liquor spool 3, push rod 7 and back fluid spool 2 reset under spring force and action of hydraulic force, and feed liquor spool 3 and valve seat 8 are closed, and stop feed flow, and back fluid spool 2 separates with push rod 7, and connect with liquid return hole O.If reverse operating, a cover mechanism action of its opposite side is identical.
Hydraulic control guide control: infeed the control working solution to inlet B or B ' respectively, back fluid spool 2 moves under action of hydraulic force, closes liquid return hole O, promotes push rod 7 and backs down feed liquor spool 3, and spring 15 is compressed, and pump liquid flows to outlet A (A ') by the P mouth.After hours, B (B ') mouthful stops to infeed the control working solution, and feed liquor spool 3, push rod 7 and back fluid spool 2 reset under spring force and action of hydraulic force, and feed liquor spool 3 and valve seat 8 are closed, and back fluid spool 2 separates with push rod 7, and connects with liquid return hole O.One cover mechanism action of opposite side is identical.
Manual-operating mechanism can be finished this support single movement.The guide controls liquid inlet B, B ' can accept the control working solution that adjacent frame and shelf infeed, and makes two supports finish composite move simultaneously.
