Abstract
The utility model relates to a grouting hole packer with an air exhaust pipeline. The grouting hole packer is characterized in that a grouting inner pipe wall is arranged on the inner wall of an outer pipe; a grouting pipeline is formed between the grouting inner pipe wall and the inner wall of the outer pipe; an emptying inner pipe wall is arranged on the inner wall of the outer pipe at the position corresponding to the grouting inner pipe wall; an emptying pipeline is formed between the emptying inner pipe wall and the inner wall of the outer pipe; the outer pipe, the grouting inner pipe wall and the emptying inner pipe wall adopt an integrated structure; a grout inlet and a grout outlet are formed in one side of the outer pipe, and communicated with the grouting pipeline; an air outlet and an air exhaust are formed in the other side of the outer pipe, and communicated with the emptying pipeline; the air outlet is connected with an exhaust pipe through an elbow; the two ends of the grouting pipeline are sealed through sealing bolts A; the two ends of the emptying pipeline are sealed through sealing bolts B. According to the utility model, the air exhaust pipeline is added, air in the hole packer can be exhausted in the use process, bubble problem in the grouting can be removed, and the blocking effect is good.
Description
Technical field
The utility model relates to a kind of fluid filling hole sealing device with extract duct.
Background technology
Under coal mine, the common effect of extraction coal-bed gas is bad at present, now generally typically use common hole packer shutoff, though can play plugging action, but hole packer is irony material with drainage gas pipe inner core, heavy not only, and in use procedure because all extraneous factor irony pipes easily produce spark, so very easily cause the explosion accident of gas, use dangerous.According to above factor, work out the patent that the patent No. is " 201410106672.0 ", this patent hole packer inner core is to adopt fire retardant antistatic plastic material to make, solve above-mentioned irony pipe and easily produced the problem that spark causes explosion accident, but the emptying problem while in use there is again hole-sealing grouting, air between hole packer cannot be discharged and be caused shutoff not tight, and plugging effect is bad.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of fluid filling hole sealing device with extract duct is provided, the utility model solves the technical scheme that its technical problem adopts: structure of the present utility model comprises outer tube, slip casting inner tubal wall, grouting pipe, annular one way valve, emptying inner tubal wall, emptying pipe, grouting port, grout outlet, gas outlet, exhaust opening, sealing bolt A, sealing bolt B, it is characterized in that being provided with slip casting inner tubal wall on the inwall of outer tube, between slip casting inner tubal wall and outer tube wall, form a grouting pipe, position relative with slip casting inner tubal wall on the inwall of outer tube is provided with emptying inner tubal wall, between emptying inner tubal wall and outer tube wall, form an emptying pipe, outer tube and slip casting inner tubal wall and emptying inner tubal wall three are structure as a whole, on outer tube, a side is provided with grouting port and grout outlet, grouting port and grout outlet are all connected with grouting pipe, on outer tube, opposite side is provided with gas outlet and exhaust opening, gas outlet and exhaust opening are all connected with emptying pipe, gas outlet is connected with stack by elbow, the two ends of grouting pipe seal by sealing bolt A, the two ends of emptying pipe seal by sealing bolt B.
The utility model is adopted made of plastic, compound rubber Dilated rubber hose and safety valve use, during use, between hole packer A and hole packer B, pass through soft pipe connection, hole packer B is common without emptying pipe structure, hole packer A is band emptying pipe structure, hole packer A is upper is used for installing elbow with two boss of drainage gas pipe grouting, Jin Jiang one end, one end pulp, one end of pulp is communicated with hole packer B by tube connector, slip casting passage in drainage gas pipe is for slip casting, the sealing material injecting flows out from the grout outlet in the middle of drainage gas pipe, for the rubber swelling sebific duct expanding outside drainage gas pipe, on drainage gas pipe, the effect of the annular one way valve at grout outlet place is to prevent slurry adverse current, and two of emptying use boss on drainage gas pipe, what spare and accessory parts inner end exhaust opening boss does not take over, gas outlet boss is used for installing elbow and connects stack, emptying detection mouthful is installed in stack outer end, but an emptying detection mouthful place illustrates that the air between hole packer drains while having slurry to flow out, then slip casting is tight by coal seam shutoff.
The beneficial effects of the utility model are, the utility model has increased emptying pipe, in use that the air between hole packer is emptying, the air bubble problem occurring in the time of can removing slip casting, and shutoff is tight, and plugging effect is good.
