Claims

The invention relates to mining and is intended to block the degassing pipelines of a mine gas installation connecting the drainage wells with the equipment of the degassing station of the mines. A reducing valve is known, containing a upper body, a gray-haired and differential plunger, the end of which is made with through holes located at the interface of the plane of the plunger face with fillet l. However, this valve does not allow continuous measurement of gas flow in the drainage well. Closest to the proposed technical solution is a valve device for shutting off degassing pipelines, including its case with flange connections, and a compression spindle with a valve plate at its end 2. However, the known valve device also does not allow continuous measurement of gas pressure in the drainage well, moreover, this device cannot provide connection of the drainage wells simultaneously to the gas installation and to the drainage device. The purpose of the invention is to improve the efficiency of the degassing pipeline through the possibility of continuously controlling the concentration and pressure of gas in the drainage well. The goal is achieved by the fact that the valve spindle's inlet spindle is made with an internal concentrically arranged through channel and is equipped with a gas valve installed at its free end, while the valve plate is made in the form of support washers and enclosed between these flexible seals and fixed to the spindle by means of the nuts. FIG. 1 and 2 shows the proposed device. The valve device consists of a three-way body 1 with a threaded or flanged nipple 2, terminating valve seat 3, from the head 4 in the outgoing 5, in which the spindle b is fitted with a bore 7 on the driver side 8 with a closed stopper 9 and / or a gas valve 10 sampling. On the spindle b with channel 7 from the valve seat side, on the narv eann of its part, the nut 11 and the base 12 of the valve plate are seated. Parallel to the base 12 on the spindle 6, an elastic sealing washer 13, a washer 14 and a clamping nut 15 are successively seated. The valve head 4 in its base is directly above the nut 11 of the valve plate and has 16 and 10 Spuddel 6 fitted on the outer and inner surfaces holding the valve device in an open or closed state. On the side of the knob 8, the space between the head 4 and the blade is filled with a gasket 17 pressed by a stopper 18. A guide 5 fitted with smooth apertures 16 is seated in the head 4 and is connected with the internal and external threads. The connection is made using a threaded coupling 19 with a safety screw 20. To extract the gas from the drainage well or to check the pressure in it or in a gas installation in the closed state of the valve device, it is necessary to unscrew the plug 9 or open the gas valve 10 closing the channel .7 spindle 6. In the case of use, to close the channel 7 of the gas valve 10, it is sufficient to connect a shaft manometer or other measuring device to it with a hose, and then open the valve 10 and read off the methane content mine gas suction mixture, gas pressure in the well, as well as well flow rate. In the case of the use of the plug 9, the flexible hose should be led into this channel by means of a sealing ring 7. By placing these valves in gas shut-off, both underground and surface, it is possible to make measurements of gas analyzes in all gas installations, in particular, before and after the degassing station, as well as at the station itself, which will increase the efficiency of degassing. Claim device for shutting off degassing pipelines, including a housing with flange connection and an inlet spindle with a valve plate at its end, characterized in that The sliding spindle is made with an internal concentrically located through channel and is equipped with a gas valve installed at its free end, with The volume of the valve plate is made in the form of support washers and a flexible seal enclosed between them and fastened to the spiidel by means of nuts.
