Abstract
The utility model discloses a mining wind and water three-joint quick conversion valve for relieving water pressure in a drilling process of a coal road and during upward discharge in drilling of a rock roadway by an underground gas drainage rig of a coal mine. A water inlet (2) of the valve is arranged at the right end of a valve body (1), an air inlet (3) is arranged at the lower end of the valve body (1), a water and air outlet (4) is arranged at the left right of the valve body (1), and a spherical valve core (6) is movably arranged in the middle of the valve body (1). As the three-joint valve is designed, quick conversion of wind and air can be realized in drilling of the rock roadway by means of rotation of the spherical valve core and an arc-shaped cone-shaped groove on the upper side in the valve body, so that the time is saved, the materials are saved, the working speed is improved, the safety is ensured, and the mining wind and water three-joint quick conversion valve is quick and convenient to use.
Description
Technical field: unload diminishing during row's operation that utility model relates to a kind of coal mine gas cross drainage drilling machine in the coal roadway drilling operation process and in the rock gangway boring and press the quick switching valve of mining geomantic omen threeway that uses.
Background technology: at present during the downhole production of colliery for safety, gas pumping is to solve the particularly essential measure of particularly serious gas accident of present China's coal-mine gas accident, the first step is exactly in coal, rock gangway boring in this extraction process, an important job step in boring procedure is exactly to use wind and water that the coal in the drilling hole, rock are blown, go out boring, and existing wind and the water that uses all is to finish switch wind, water with common stop gate.In the coal road operation process, sometimes use wind, when particular case is arranged, wind and water are changed.Usefulness is two stop gates now, a boiling water, and one closes wind, or one blows in, and one closes water.Stamp gang drill at the rock gangway water in addition, during boring, when a drilling rod has bored, in the time of need connecing next root drilling rod, unload injector, in tens meters dark boring from top to bottom the water in the drilling rod naturally flow out, in order to save time, do not wait water just to flow in the drilling rod injector is connected drilling rod, water can be mingled with gas in the top-down inertia impact of water and centre from drilling rod mouth and injector mouth and producing a kind of pressure like this, water is from then on ejection just, personnel's clothes of drilling rod operation is got wet, and this is large for invar sometimes, and injector does not connect drilling rod, needs wait water and gas all to discharge, and injector just can connect drilling rod.
The utility model content: the purpose of this utility model has been to overcome the drawback of the geomantic omen valve existence of present use, provide a kind of arc-shaped gaps of spherical valve core and valve body internal upper part of utilizing to be rotated, can realize the quick conversion of water, wind, save time, improve the quick switching valve of mining geomantic omen threeway that operating rate is used.The technical scheme that the utility model adopts for achieving the above object is: its water inlet 2 is arranged on valve body 1 right-hand member, and air inlet port 3 is arranged on valve body 1 lower end, and water outlet, air port 4 are arranged on valve body 1 left end, and spherical valve core 6 is movably placed in valve body 1 interior middle part.
The beneficial effects of the utility model are: owing to having designed three-way valve, utilize the arc-shaped gaps of spherical valve core and valve body internal upper part to be rotated, when rock gangway is holed, need use the loaded down with trivial details of two gates when having avoided with wind conversion water, stacks can not rehumidify clothes, cold winter job particularly, greatly improved the comfortableness of health, no longer the pressure of this and water of invar does not connect greatly injector, and can realize the quick conversion of water, wind, has saved the time, saved material, improved operating rate, guaranteed safety, and used efficient and convenient.
Description of drawings: Fig. 1 is sectional view of the present utility model
The specific embodiment: as shown in Figure 1, its water inlet 2 is arranged on valve body 1 right-hand member, and air inlet port 3 is arranged on valve body 1 lower end, and water outlet, air port 4 are arranged on valve body 1 left end, and spherical valve core 6 is movably placed in valve body 1 interior middle part.
As shown in Figure 1, described spherical valve core 6 interior middle parts arrange through hole 7, and valve body 1 one sides arrange rotary handle 8.
As shown in Figure 1, described valve body 1 internal upper part arranges arc cone groove 5.
Claims (3)
1. quick switching valve of mining geomantic omen threeway, it is characterized in that water inlet (2) is arranged on valve body (1) right-hand member, air inlet port (3) is arranged on valve body (1) lower end, water outlet, air port (4) are arranged on valve body (1) left end, and spherical valve core (6) is movably placed in middle part in the valve body (1).
2. the quick switching valve of mining geomantic omen threeway according to claim 1 is characterized in that the middle part arranges through hole (7) in the described spherical valve core (6), and valve body (1) one side arranges rotary handle (8).
