Abstract
A single-control spray water valve for a coal mine hydraulic support comprises a valve body and valve core assemblies, wherein a valve cavity, a liquid outlet, a liquid inlet and a control opening are formed in the valve body; the liquid outlet, the liquid inlet and the control opening are communicated with the valve cavity; an ejector rod and a set of valve core assemblies are mounted in the valve cavity; the valve core assemblies are composed of a threaded sleeve, a valve rod, a valve sleeve, a valve pad, a bush and a spring; and the upper end of the threaded sleeve is connected with the lower end of the valve sleeve in such a manner that rivets are locked with each other so that the whole valve core assembly is formed into an integrated body so as to be conveniently mounted in the valve body or demounted from the valve body. The single-control spray water valve is quick to repair, reliable in performance and capable of effectively guaranteeing normal production.
Description
Technical field
The utility model relates to a kind of coal mine hydraulic supporting single control water injection valve.
Background technology
Water injection valve is coal mine hydraulic supporting a kind of water spray control element commonly used, and it is reasonably combined with the hydraulic system of coal mine hydraulic supporting, can realize automatic water jetting, effectively reduces the dust pollution of coal-face, guarantee operating personnel's health.But at present water injection valve structure commonly used is comparatively complicated, the dismounting difficulty, and maintenance time is long, and repair quality can not be fully guaranteed, and has a strong impact on normally carrying out of production.
The utility model content
The purpose of this utility model is to provide a kind of dependable performance, is easy to a kind of coal mine hydraulic supporting single control water injection valve of quickly dismantled maintenance.
The solution of taking for the utility model that achieves the above object is: a kind of coal mine hydraulic supporting single control water injection valve, it comprises valve body and core assembly, have valve pocket, liquid outlet, inlet and control mouth in the valve body, liquid outlet, inlet, control mouth communicate with valve pocket, a push rod and a cover core assembly are housed in the valve pocket, core assembly is comprised of swivel nut, valve rod, valve pocket, valve pad, lining, spring, the swivel nut upper end is connected with the mode that the valve pocket lower end adopts rivet to interlock, and makes a whole set of core assembly become as a whole.
The utility model has the advantage of that described core assembly is that a cover is whole, in the valve body of can packing into easily or from valve body, split out, maintenance rapidly, dependable performance effectively ensures normally carrying out of producing.
