Abstract
An automatic spraying control valve for a hydraulic support comprises a valve body and a check valve and is characterized in that a step-shaped valve cavity is formed in the valve body in a penetrating mode, a liquid outlet, a liquid inlet and a control opening (6) are communicated with the valve cavity and formed in the valve body, the check valve is arranged in the valve cavity, the check valve is composed of a rod sleeve, an ejector rod, a seat sleeve, a valve seat, a valve plug, a spring and an end sleeve, the end face of the lower end of the rod sleeve is fixedly connected with the end face of the upper end of the end sleeve, the conical surface hard sealing is conducted on the valve seat and the valve plug, and the valve seat is made of polyformaldehyde materials. The automatic spraying control valve for the hydraulic support is compact is structure, reliable in sealing performance and convenient and rapid to detach, assemble and maintain.
Description
Technical field
The utility model relates to a kind of control valve, refers in particular to a kind of hydraulic support automatic spray control valve.
Background technology
Spray control valve is coal mine hydraulic supporting a kind of water spray control element commonly used, the hydraulic system of it and coal mine hydraulic supporting is reasonably combined, can realize auto spraying, effectively reduce the dust pollution of coal-face, ensure operating personnel's health, but water injection valve structure commonly used at present is comparatively complicated, sealing performance is not good, the dismounting difficulty, and maintenance time is long, and repair quality can not be fully guaranteed, and it is healthy to have a strong impact on the underground labour.
The utility model content
The purpose of this utility model is to provide a kind of hydraulic support automatic spray control valve, its compact conformation, and sealing performance is reliable, is convenient to the quickly dismantled maintenance.
The solution of taking for the utility model that achieves the above object is: a kind of hydraulic support automatic spray control valve, it comprises valve body and one way valve, it is characterized in that: have a valve pocket that connects the valve body step in the described valve body, and offer the liquid outlet that communicates with valve pocket on the valve body, inlet and control mouth, be provided with a cover one way valve in the valve pocket, described one way valve is by the bar cover, push rod, cover for seat, valve seat, spool, spring, the end cover is formed, bar cover lower end is connected and fixed with end set upper side end face, valve seat and spool are that the conical surface seals firmly, and valve seat adopts polyformaldehyde material to make.
Advantage of the present utility model is that the inlet of control valve is connected with the additional line of hydraulic support, liquid outlet is connected with spray assembly, the control mouth is connected with the working chamber of column cavity of resorption or passing jack, after increasing this redundant mesh, when column descends or passes jack when overhanging, control mouthful place's pressure promotes push rod and backs down spool, working media sprays through the spray assembly of valve pocket from liquid outlet from inlet, reduction is advanced down, and working environment is suspended in airborne dust, improved greatly because abominable healthy to coal miner of subsurface environment, its compact conformation, sealing performance is reliable, be convenient to the quickly dismantled maintenance, valve seat adopts polyformaldehyde material and the spool conical surface to seal firmly, has improved the application life of product greatly.
