Description
Technical Field
The utility model belongs to the technical field of drilling gas prevents spouting, relate to blowout preventer, specifically be a blowout preventer Kong Nangdai through device is prevented in pit coal mine.
Background
When the underground coal mine construction is drilled, the blowout preventing device is widely applied to a drilling construction site and is used for preventing gas from exceeding the limit. The use method of the orifice prevention device in the previous stage is that after hole drilling and reaming, the through hole at the front end of the orifice prevention device is plugged into the hole, and hole sealing materials are used for sealing between the through hole and the hole wall, as shown in figure 1, the through hole is isolated from the outside through the through hole device, and the hole sealing materials cannot be reused, so that resource waste is caused. Because the existing hole sealing material is a high-molecular inflammable material, under the condition of high gas concentration, certain danger exists, and the existing hole sealing material cannot be used continuously. For the above reasons, the invention blowout prevention Kong Nangdai straight-through device is used to solve the problem.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is inflammable to aim at solving current hole sealing material, and the danger coefficient is big under the condition of high gas concentration, so the technical problem that can't continue to use provides a well industry coal mine prevents spouting Kong Nangdai straight-through device.
The utility model provides a technical means that its technical problem adopted is: the utility model provides a blowout prevention Kong Nangdai through device for underground coal mine, is including being connected to the through of preventing orifice device front end, and the through wherein one end links firmly the ring flange, and direct outer wall middle part cover is equipped with the bag, and the both ends of bag are connected with through sealing respectively through the retaining member, are provided with the water filling port on the bag, install the stop valve on the water filling port. When the straight through hole is required to be taken out, the stop valve is opened, the water is discharged, the bag is contracted, and the straight through hole is taken out.
Preferably, the outer surface of the through is coated with a rust inhibiting coating. This is in order to prevent to lead to behind the external contact water scaling corrosion, and anti rust coating can prolong the utility model the life of straight-through device.
Preferably, the bladder is made of an elastomeric material that is resistant to high pressure and abrasion. Such as the inner layer material of a basketball. The whole bag meets the requirements of strength and pressure, and the using effect is ensured.
The utility model has the advantages that: simple structure, convenient to use, the cost of manufacture is lower, during the use, will directly stretch into drilling, fill water in the bag, until the drilling is filled up sealed back, close the stop valve, play the inside and outside effect of isolated hole, the bag is feasible variable structure moreover, can realize sealed butt with the inner wall of drilling, and is sealed effectual, when needs take out directly, opens the stop valve and drains after, the bag shrink, take out directly can.
