Abstract
The utility model discloses a water injection valve, comprising a valve body and a valve cavity excavated in the valve body. The valve cavity is provided with one-way valve compact and connector. The advantages of the utility model are: the utility model is compact in structure and can be installed and repaired in the mine at certain conditions. The water inlet port of the water injection valve is connected with the additional waterway of the pneumatic support, and the water outlet of the water injection valve is connected with the nozzle; a control port is connected with the lower cavity of the vertical pole or the cavity of the jack; with the additional waterway, when the vertical pole is lowered down or the jack is outstretched, the pressure piston at the control port push the valve core open, the water is spraying out through the water outlet after going through the water inlet and the valve cavity; therefore, the utility model effectively wipes off the smut in the air, and the harm of the smut to the worker is maximum lessened, and the underground circumstance is improved. The valve seat made of polyformaldehyde material matches with the cone face of the valve core, greatly prolonging the life span of the valve.
Description
Technical field
The utility model relates to pilot operated valve device, especially relates to the hydraulic control water injection valve that is used for hydraulic support.
Background technology
In the colliery industry, the working environment of down-hole is extremely abominable, particularly on coal-face, has been full of coal dust in the air, and it is very serious to miner's actual bodily harm to work in this environment for a long time.But, also there is not effective method to improve this situation by the end of at present.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, plug-in water injection valve easy to maintenance.
For achieving the above object, the utility model can be taked following technical proposals:
Water injection valve described in the utility model comprises valve body, is opened in the valve pocket in the valve body, is provided with one way valve group and joint in described valve pocket.
Described one way valve group is by the valve casing that offers runner that is connected with described valve pocket thread seal and be arranged on spool in the described valve casing, constitutes valve rod, back-moving spring, the piston that the valve seat of sealing and vavle shelf, operation spool open and close with described spool and constitutes; Described piston thread is connected in the left end of described valve rod; Vavle shelf, valve seat, spool, back-moving spring are sleeved on the valve rod from left to right successively; Described valve casing extends outside the valve body, is provided with screw plug in the valve casing right output port; The liquid inlet and outlet of described one way valve group is connected with fluid pressure line by the runner that is opened on the valve body.
The fitting face of described valve seat and spool is the conical surface, and valve seat adopts polyformaldehyde to make.
Advantage of the present utility model is compact conformation, is convenient to the installation and maintenance in this specific environment of down-hole.The water inlet of this water injection valve is connected with the additional water route of hydraulic support, delivery port is connected with nozzle, the control mouth walks abreast with the working chamber of column cavity of resorption or passing jack and is connected, after increasing this redundant mesh, when column descends or passes jack when overhanging, the pressure at control mouthful place promotes piston and backs down spool, water sprays through the nozzle of valve pocket from delivery port from water inlet, can effectively remove the coal dust particulate of airborne suspension, reduced the harm of coal dust to greatest extent, the environment of down-hole is improved greatly the miner.The structural advantages of this valve also be with the valve seat of described one way valve group, spool, back-moving spring, piston from a left side and the right side be sleeved on the valve rod in mode movingly successively, therefore only need dismantle whole string valve during maintenance and installation and get final product, greatly facilitate the installation and maintenance work under the specific environment of down-hole.Valve seat adopt polyformaldehyde material make and with the spool cone match, improved application life greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As described in Figure, water injection valve described in the utility model comprises valve body 1, is opened in the valve pocket in the valve body 1, is provided with one way valve group and joint 2 in described valve pocket.Described one way valve group is by the valve casing that offers runner 3 that is connected with described valve pocket thread seal, with the spool 4 that is arranged in the described valve casing 3, constitute valve rod 7, back-moving spring 8, the piston 9 that the valve seat 5 of sealing and vavle shelf 6, operation spool 4 open and close with described spool 4 and constitute; Described piston 9 is threadedly connected to the left end of valve rod 7; Vavle shelf 6, valve seat 5, spool 4, back-moving spring 8 are sleeved on the valve rod 7 from left to right successively; Described valve casing 3 extends outside the valve body 1, is provided with screw plug 10 in valve casing 3 right output port; The liquid inlet and outlet of described one way valve group is connected with fluid pressure line by the runner that is opened on the valve body 1.Described valve seat 5 is the conical surface with the fitting face of spool 4, and valve seat 5 adopts polyformaldehyde to make.
