Problems solved by technology

[0003] The purpose of the present invention is to overcome the inconvenient connection of the existing gas drainage orifice valves to the gas connection system. When a single gas drainage pipe is blocked by cinders, the system cannot be disconnected and the system can be cleaned separately, so as to realize a It is a kind of coal mine gas drainage that can conveniently connect different angles of gas connecting pipe systems together, and conveniently disconnect a single blocked gas drainage pipe from the entire gas drainage system, and dredge the blocked single hole Angle Adaptive Unblockable Node Valve for Holes

Embodiment 1

[0031] The angle self-adaptive dredging node valve for coal mine gas drainage holes of the present invention includes a valve body 1 and a valve core 2 that can rotate inside the valve body. The valve body 1 is T-shaped. The openings are respectively a fluid inlet 101, a fluid outlet 102 and a dredging port 103, and the fluid inlet 101 and the dredging port 103 are collinear, and the fluid inlet 101 and the fluid outlet 102 are arranged at right angles; the valve core 2 is provided with a T-shaped communication hole, The front end of the T-shaped communication hole on the spool 2 corresponds to the fluid inlet 101, the lower end of the T-shaped communication hole corresponds to the fluid outlet 102, and the rear end of the T-shaped communication hole corresponds to the dredging port 103; the side of the valve core 2 corresponding to the dredging port 103 is detachable A valve body switch sealing mechanism 3 is provided, the valve body switch sealing mechanism 3 includes a rotat...

Embodiment 2

[0037]The same as embodiment 1 will not be repeated, the difference is: the flexible pipe structure 4 is detachably connected to the fluid outlet 102 of the valve body through the threaded structure 11, and the flexible pipe structure 4 includes a threaded spring skeleton 401 and an elastic plastic covering layer 402 , the elastic plastic covering layer 402 and the threaded spring frame 401 are secondary injection molded.

Abstract

The invention relates to a valve special for a coal mine gas drainage system, in particular to an adaptive-angle dredging node valve used for a coal mine gas drainage hole. The adaptive-angle dredging node valve comprises a valve body and a valve element. The valve body is in a T shape. A T-shaped communicating hole is formed in the valve element. The front end of the T-shaped communicating hole in the valve element corresponds to a fluid inlet. The lower end of the T-shaped communicating hole corresponds to a fluid outlet. The rear end of the T-shaped communicating hole corresponds to a dredging port. A valve body switch sealing mechanism is arranged on the side, corresponding to the dredging port, of the valve element in a detachably matched mode. A flexible pipe structure with the angle adjustable is arranged in the fluid outlet end of the valve body in a communicating mode. The adaptive-angle dredging node valve used for the coal mine gas drainage hole is low in cost, one single gas drainage hole can be conveniently disconnected from the whole gas drainage system so as to be dredged, and the adaptive-angle dredging node valve can adapt to flexible connection between a horizontal connecting pipe system and different gas drainage holes of different drilling angles.

Description

technical field [0001] The invention relates to a special valve for a coal mine gas drainage system, in particular to an angle self-adaptive dredging node valve for a coal mine gas drainage hole. Background technique [0002] The pipeline connection of the coal mine gas drainage system generally uses antistatic PVC or PE plastic pipes and pipe fittings, and most of them borrow antistatic standard parts for civil gas or natural gas. Common ball valves, elbows and tees are used for pipeline connection, and it is inconvenient to connect the gas drainage pipe with an upward and downward inclination angle with the horizontally arranged gas connecting pipe system; the general ball valve is inconvenient to adjust and cannot be drained according to each gas The gas concentration of the hole is finely adjusted to flow, which is not conducive to the control of gas concentration. When a single gas drainage pipe is blocked by cinders, the system cannot be disconnected for separate clean...
