Abstract
An insertion type hydraulic control one-way valve for a suspended support comprises a valve body which is welded with a connector seat. A valve cavity, an A1 port, an A2 port, an A3 port, a P1 port, a P2 port, a K1 port, a K2 port and a K3 port are formed in the valve body. The A1 port, the A2 port, the A3 port, the P1 port, the P2 port, the K1 port and the K2 port are communicated with the valve cavity. A one-way spool is in rigidity seal with a conical face of a valve seat. A screw sleeve, an ejector pin, a large spring, a middle sleeve, the valve seat, the one-way spool, a small spring and a valve sleeve form a spool component through fastening screws. The spool component which serves as an integral inserting part is mounted into the valve cavity. By the insertion structure, the hydraulic control one-way valve is compact in structure, convenient to mount and maintain, reliable in seal close performance, flexible in action and low in pressure loss.
Description
Technical field
The present invention relates to a kind of one way valve, the cantilever support plug-in hydraulic control one-way valve that to refer in particular to a kind of metered flow for the coal mine fully-mechanized mining working hydraulic support be 125L/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
5 liquid-through holes.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.
Summary of the invention
The object of the present invention is to provide a kind of metered flow for the coal mine fully-mechanized mining working suspension moving hydraulic support is the hydraulic control one-way valve of 125L/min, and it adopts plug-in structure, compact conformation, be convenient to installation and maintenance, the hermetically closing dependable performance is active in one's movements, and the pressure loss is little.
For achieving the above object, the solution that the present invention takes is: a kind of plug-in cantilever support plug-in hydraulic control one-way valve, it comprises valve body, valve body and plinth welding, valve body has valve pocket, the A1 mouth, the A2 mouth, the A3 mouth, the P1 mouth, the P2 mouth, the K1 mouth, the K2 mouth, the K3 mouth, the A1 mouth, the A2 mouth, the A3 mouth, the P1 mouth, the P2 mouth, the K1 mouth, the K2 mouth communicates with valve pocket, nonreturn valve core and the valve seat conical surface seal firmly, swivel nut, push rod, big spring, middle cover, valve seat, nonreturn valve core, little spring, valve pocket is formed core assembly by trip bolt, and core assembly is made as a whole plug connector and packed in the valve pocket.
It links to each other with the column upper and lower cavity by connecting bolt, easy accessibility, compact conformation.Nonreturn valve core and the valve seat conical surface seal firmly, 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.
Its operating principle is: when reversal valve to P1 mouth, P2 confession liquid, under the effect of hydraulic coupling, overcome the spring force of little spring, back down the nonreturn valve core assembly, liquid enters column cavity of resorption feed flow from valve pocket through the A3 mouth, thereby make column (jack) setting prop, when column was raised to working resistance, reversal valve stopped feed flow, unidirectional core assembly and big valve base sealing sealing guarantee the column continuous firing under hydraulic coupling and spring force effect.When reversal valve during to K1 mouth or K2 confession liquid, liquid promotes push rod, backs down nonreturn valve core, and liquid flows back to emulsion box from A3 through P1, P2 mouth, realizes falling post.
