Abstract
The utility model relates to a fully mining and discharging, stent supporting and moving and coal discharging linkage spraying system valve, which combines a controlling valve and a spraying device into a whole body. The utility model consists of a valve body, a controlling joint, a water inlet and a nozzle. The spraying valve is connected on the liquid supply circuit of the caving coal stent inserting plate jack or the support column through a high pressure oil pipe, the water inlet is arranged on the dustproof water pipeline, and a nozzle is arranged on the spraying port. When the liquid coal caving is supplied to the inserting plate jack, the emulsion can enter into the linkage spraying valve through the high pressure oil pipe to push the valve rod, and the valve rod pushes the cone, thus the dustproof water pathway is opened to spray and make the dust fall automatically. When the inserting plate stretches out, the former liquid supply cavity changes to a liquid returning cavity, the dustproof water pathway is opened by the back pressure of the liquid returning cavity pushing the cone to spray and make the dust fall. When the operating valve stops supplying liquid, the cone pushes the valve rod reduction under the effect of the spring force, namely the dustproof water pathway is cut off and the spray is stopped. The working mechanism is the same when the liquid control pipe is connected to the liquid supplying circuit of the fully mining support column. The spraying valve is small in volume, firm in structure, convenient for installing, very convenient for maintenance.

Summary of the invention
The purpose of this utility model provides a kind of comprehensive synthetical support of adopting and moves frame and put coal interlock spraying one valve, overcome existing auto spraying control device fault rate height, fragile, the sealing of its hydraulic control spray valve was easily lost efficacy, the hydraulic part easy-to-rust causes that action is dumb, pipe-line system is complicated, rapid wear, defectives such as maintenance is big, and can realize moving frame and put that the coal overall process is sprayed continuously, depositing dust.
The utility model is realized with following technical scheme: a kind of comprehensive synthetical support of adopting moves frame and puts coal interlock spraying one valve, comprise the cuboid valve body that is fixed on the support, valve rod is fixed on valve body one side and the double control joint of doing valve body, water inlet and nozzle, it is characterized in that: through hole one end of valve body middle and lower part is by the fixing control of screw thread joint, the fast joint of control joint outer end is installed the hydraulic control pipe, in the hole of control joint valve rod is installed, two O RunddichtringOs of valve rod and the interior installation of the seal groove of the contact surface of control joint, the end of valve rod contacts with the end face of cone, cone is sleeved in the taper hole of tapered sleeve, tapered sleeve is pressed abd fixed on by plug in the hole of valve body, clamps the compression spring between the face of cylinder of cone one end and the hole of plug; Water inlet vertically is produced on the bottom of valve body, and the big end of upper end and tapered sleeve connects, and the delivery port lower end makes fast joint and admitting pipe joint links; Some nozzles of equidistant making on the covering of the fan vertical of valve body top with cone and and cone and valve body between cavity connect; Two O RunddichtringOs are installed in the groove of tapered sleeve both ends of the surface; Between plug middle part and the valve body O RunddichtringO is installed.
The beneficial effects of the utility model are:
(1) control valve and atomization mechanism are integrated, compact conformation, system is simple, has saved the part pipe-line system, has reduced the trouble point, is convenient to safeguard.
(2) control valve and atomization mechanism are integrated, all parts all on a valve body, be convenient to install, and only needs a hydraulic control pipe by sound construction, and a feed pipe gets final product.
(3) interlock spraying one valve control system is simple, and compact conformation is reasonable, and component are not fragile, repairs or changes sealing ring and only need dismantle plug, takes out valve rod and gets final product.
(4) switch in employing cone and tapered sleeve structure control water route has guaranteed that valve body can be active in one's movements reliably good seal performance, long service life.
(5) valve body adopts three nozzles to be radial arrangement, though valve body structure is small and exquisite, the water smoke of ejection can produce coal discharge outlet at the dirt position and cover comprehensively, reduces coal dust to greatest extent.
