Abstract
The utility model discloses a hydraulic automatically hole sealing coal seam flooding equipment for gas and coal dusts downhole of coal mines, which comprises a water injecting valve, a connector, a connecting rod, a fastener inner core, an outer hoop, an expansion rubber bag, a nozzle, a steel ball and a pressure-adjusting spring. The water injecting valve comprises a valve lagging, a valve inner core, a water reversed ball and a pressure spring and is connected with the connecting rod back by the connector. The water injecting valve clamps the two ends of the expansion rubber bag between the fastener inner core and the outer hoop by the external wall of the fastener inner core and the internal wall of the outer hoop. The fastener inner core in front of the expansion rubber bag is connected with the nozzle, wherein, the steel ball and the pressure-adjusting spring are arranged on the exhalant canal inside the nozzle. The utility model has the advantages of tight structure, small labor intensity, easy operation as well as releasing automatic injection and holes sealing of different depth of holes.
Description
Technical field:
The utility model relates to a kind of automatic sealing of hole coal-bed flooding of waterpower device that is used for preventing and treating under the coal mine gas and coal dust.
Background technology:
Along with the continuous development of coal industry and Coal Production mechanization, coal and gas are given prominence to the safety in production that problems such as reaching coal-dust explosion seriously restricts the colliery, in order to solve this difficult problem, have taked many prophylactico-therapeutic measuress, and coal-bed flooding is exactly one of comparatively advanced measure.The injector that uses adopts the water filling of mechanical type cushion rubber sealing of hole at present, it is O-ring seal to be set on the water injection pipe also be inserted in the boring simultaneously, extruding disk and the depression bar rotation of at first operating machine is screwed into extruding, sealing ring is expanded and the realization sealing of hole, and then carry out water filling, because the restriction of injector structure, cause that hole sealing depth is shallow, labour intensity big, the personnel that take are many and efficient is low.
The utility model content:
The purpose of this utility model provides the automatic sealing of hole coal-bed flooding of the waterpower device that a kind of compact conformation, labour intensity are little, easy and simple to handle, can realize the automatic water filling sealing of hole of different hole depths.
To achieve these goals, the utility model comprises: water injection valve, connector, connecting rod, the fastener inner core, outer hoop, the expansion capsule, faucet, steel ball, pressure spring, water injection valve is by the valve overcoat, the valve inner core, ball against the current, pressure spring constitutes, water injection valve is connected with the connecting rod rear end by connector, respectively the two ends of expansion capsule are clipped between fastener inner core and the outer hoop by the outer wall of fastener inner core and the inwall of outer hoop, the fastener inner core of expansion capsule rear end is connected with the front end of connecting rod, the fastener inner core of expansion capsule front end is connected with faucet, and the exhalant canal of faucet inside is provided with steel ball and pressure spring.
Like this, when water filling in the coal seam, the utility model is inserted in the boring, be connected the beginning water filling by water system with water injection valve with fluid injection gun, expand charged pressure water in the capsule this moment and expand that to become senior general's borehole sealing tight, realize the automatic sealing of hole of waterpower, after continuing water filling and making hydraulic pressure greater than the pressure spring pressure in the faucet, steel ball is backed down, and water under high pressure will be injected in the coal seam by faucet.How much the water filling degree of depth of water injection hole adjusts if can increasing and decreasing the quantity of connecting rod, have compact conformation, labour intensity little, easy and simple to handle, can realize characteristics such as the automatic water filling sealing of hole of different hole depths, can prevent and treat the outstanding and coal-dust explosion of coal and gas effectively.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a semi-section structural representation of the present utility model.
Fig. 2 is expansion capsule and termination connection semi-section structural representation thereof.
The specific embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: water injection valve, connector 5, connecting rod 6, fastener inner core 7, bind round 8 outward, expansion capsule 9, faucet 10, steel ball 11, pressure spring 13.Water injection valve is by valve overcoat 1, valve inner core 2, ball 3, pressure spring 4 constitute against the current, valve overcoat 1 is used to connect the water system fluid injection gun, ball 3 installs in valve overcoat 1 with pressure spring 4 against the current, ball 3 gets lodged on the water injection valve inner passage making against the current under the effect of pressure spring 4 under the normal condition, during water filling against the current ball backed down, when stopping water filling against the current ball close.Water injection valve is connected with connecting rod 6 rear ends by connector 5, and connecting rod 6 adopts seamless steel pipe to make, and can several connecting rods be linked up use according to the water filling different depth.Use firm reliability for the capsule 9 that guarantees to expand, the expansion capsule by manage 16 in the rubber, wire loop 15, external protection coating 14 bonding forming, under certain hydraulic action, can expand together, after reducing, pressure can restore to the original state together again, respectively the two ends of expansion capsule are clipped between fastener inner core 7 and the outer hoop 8 by the outer wall of fastener inner core 7 and the inwall of outer hoop 8, the fastener inner core of expansion capsule rear end is connected with the front end of connecting rod 6, and the fastener inner core of expansion capsule front end is connected with faucet 10.For the capsule two ends that guarantee to expand connect and the reliability of sealing, make expansion capsule two ends the outer wall of fastener inner core 7 with bind round between 8 the inwall formation wire inversion outward and buckle shape.Connecting between connecting rod 6 and the expansion capsule 9, between expansion capsule 9 and the faucet 10, can adopt snap joint or engage thread to carry out.The exhalant canal of faucet 10 inside is provided with steel ball 11 and pressure spring 13, steel ball is blocked exhalant canal under the normal condition under the effect of pressure spring, when water injection pressure arrives certain numerical value, the volume expansion of expansion capsule at first realizes sealing of hole, when continuing the water injection pressure rising, steel ball is backed down, and begins to carry out water filling in the coal seam.After water injection rate reached requirement, the water system fluid injection gun stopped to supply water, and pushed ball against the current 3 in the water injection valve with instrument then, and the water of injector inside is flowed out, and the expansion capsule dwindles, and pulls out injector and finishes water filling work.In order to prevent that the weep hole on the faucet 10 from being stopped up by coal dust, be provided with a plug 12 at the front end of faucet.
