Description

The plug-in hydraulic control one-way valve
Technical field
The utility model relates to a kind of hydraulic control one-way valve, the plug-in hydraulic control one-way valve that to refer in particular to a kind of metered flow that is used for the coal mine fully-mechanized mining working hydraulic support be 500L/min.
Background technology
In the prior art, the structure of hydraulic control one-way valve is varied, as Chinese patent disclosed " operating pressure is the hydraulic control one-way valve of 40MPa " (CN2763520, open day 2006.03.08), it comprises valve body, valve body has valve pocket, having K hole, B hole and O hole on the valve body communicates with valve pocket, the right-hand member of valve pocket is tightened the end bell and spigot joint, from the spring pad of the left end of valve pocket loading spring, fixed band spool successively, the metal valve of termination band valve rubber sealing mat, valve pocket, intermediate sleeve, the push rod of termination band rubber gasket, it is stifled to tighten end, has 12 on the end bell and spigot joint Liquid-through hole.It can control the direction that hydraulic cylinder, post working chamber advance, return liquid, can seal the pressure fluid of working chamber closely after closing, and has solved unloading effectively and utter long and high-pitched sounds and unload shock wave phenomenon, is used for the coal mine fully-mechanized mining working hydraulic support.But the hydraulic control one-way valve that uses is the accessory assembly type at present, owing to limited by conditions down-hole, makes to the down-hole maintenance, changes and bring inconvenience.
The utility model content
The purpose of this utility model is to provide that a kind of to be used for the metered flow that the coal mine fully-mechanized mining working hydraulic support can directly be connected with column be the plug-in hydraulic control one-way valve of 500L/min, and its compact conformation is convenient to installation and maintenance, the hermetically closing dependable performance, and flow is big.
For achieving the above object, the solution that the utility model is taked is: a kind of plug-in hydraulic control one-way valve, it comprises valve body, core assembly, joint, have valve pocket in the valve body, the A1 mouth, the A2 mouth, the A3 mouth, the P1 mouth, the P2 mouth, the K1 mouth, the K2 mouth, have the K3 mouth in the joint, the A1 mouth, the A2 mouth, the A3 mouth, the P1 mouth, the P2 mouth communicates with valve pocket, the K1 mouth, the K2 mouth communicates with the K3 mouth, the place, plane of valve body is drilled with the A hole and communicates with the P1 mouth, nonreturn valve core, little valve seat and swivel nut are formed the nonreturn valve core assembly, the nonreturn valve core assembly seals firmly with the big valve seat conical surface, valve pocket, spring, the nonreturn valve core assembly, big valve seat, guide pin bushing, push rod, big spring, joint is formed a core assembly, and core assembly is made the as a whole plug connector valve pocket of packing into.
Its available screw column direct and in the coal mine fully-mechanized mining working hydraulic support is connected, and the A hole communicates with lumen pore under the column, need not to link to each other more compact structure by connector with the column cavity of resorption.The nonreturn valve core assembly seals the hermetically closing more reliable performance firmly with the big valve seat conical surface.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.
Its operating principle is: when reversal valve to P1 confession liquid, under the effect of hydraulic coupling, overcome the spring force of big spring, back down the push rod step-down earlier, back down the nonreturn valve core assembly then, liquid enters column cavity of resorption feed flow from valve pocket through the A hole, thereby makes the column setting prop, when column is raised to working resistance, reversal valve stops feed flow, and unidirectional core assembly and big tightly sealing of valve seat guarantee the column continuous firing under hydraulic coupling and spring force effect.When reversal valve during to K1 confession liquid, liquid promotes push rod, backs down core assembly simultaneously, and liquid returns emulsion box from the A orifice flow, realizes falling post.
