Description
Technical field
The utility model relates to the colliery industry, and a kind of specifically injection hole sealing device is applied to coal body or rock mass when slip casting, water filling and plug-hole thereafter.
Background technology
Generally be to stop up with cover or cotton in the prior art, shortcoming is that inconvenient operation exists potential safety hazard, and plugging effect is bad.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of injection hole sealing device is provided, and the utility model solves the technical scheme that its technical problem adopted and is: the structure of the utility model comprises check valve assembly, tube core, ring gasket, expansion tube, flexible rubber ring, expansion via, pressure conduction element, snap joint; It is characterized in that expansion tube is the cylindrical shape of hollow, tube core is set in the expansion tube, tube core also is the cylindrical shape of hollow; Tube core runs through expansion tube and expansion tube is all stretched out at two ends; The tube core two ends are provided with external screw thread, and tube core left end set inside has check valve assembly, and the tube core right-hand member is provided with snap joint; The inside, two ends of snap joint is provided with internal thread; The tube core right-hand member is connected with snap joint through screw thread, the tube core end be provided with the pressure conduction element between snap joint is connected, the two ends of expansion tube outer wall are provided with ring gasket; Ring gasket is around expansion tube one circle; Be provided with the expansion via at the tube core middle part, the expansion via runs through tube core, and tube core outer wall middle part also is provided with a circle flexible rubber ring.
Operating principle and operation instruction: use fast, easy, the injection hole sealing device is inserted in the boring fully, with injection hole sealing device and pressure-source communication; Starting pressure, when boosting to 0.4Mpa, the sebific duct complete expansion realizes sealing of hole; This moment, safety valve was opened, to coal body water filling or slip casting.After water filling or slip casting finish; The connecting leg inhour that only needs to be connected with the injection hole sealing device screws out; The injection hole sealing device still keeps swelling state to realize long-time shutoff in boring, can guarantee effectively that interior moisture of coal body or rock body drilled or slurry branch the refluence situation can not occur.
The beneficial effect of the utility model is, the utility model is easy to use, saves time, and plugging effect is good, can realize long-time shutoff, handling safety.
