Background technique
At present for pipeline construction, when needing to drill to pipeline when such as installing instrument, what is generallyd use is all electric drill
Drilling, but its construction must be carried out in the case where pipeline interior media is " zero " pressure；Although having very extensive versatility,
In compressed air field, especially process of factory production, can face cannot stop compressing in pipeline because continuous production is run
The scene of air supply, that is to say, that have the case where medium with pressure in pipeline always, electric drill traditional at this time drills will
It is not able to satisfy, because if it is spouting to will lead to pressure medium using electric drill construction.The unresolved above problem, proposes one kind
Drilling device with pressure.
Utility model content
To solve the above problems, the utility model provides a kind of drilling device with pressure, can solve background skill
The problem of being mentioned in art.
The utility model is achieved through the following technical solutions:
A kind of drilling device with pressure, including long drill bit, bushing shell, bearing, shaft seal and ball valve, the long drill bit add
Long design, and penetrate into bushing shell, positioning ring is fixedly mounted in the middle part of the long drill bit, the positioning ring is located at bushing shell
Inside, the long drill bit are rotated upwardly and downwardly with bushing shell by two bearings and are connect, and the bearing in lower end has shaft seal；
The bushing outer casing bottom is threaded with screwed pipe, and the screwed pipe is threadedly coupled with ball valve shell, in the ball valve shell
Ball valve is installed, the ball valve shell is connected through a screw thread connector upper end, and the connector lower end is weldingly fixed on pipeline,
Bushing shell side is equipped with escape orifice；Shaft seal top long drill bit is in non-pressure free state, sealing
Interim insulating space is formed at part lower part.
Further, the mountable pressure gauge in ball valve shell top.
Further, the pipeline is water pipe or tracheae with pressure.
Further, the bushing shell is made of alloy aluminum material, and outer surface is designed to frosting.
Further, the screwed pipe uses double thread jointing, and is made of copper product.
The beneficial effects of the utility model are: the utility model realizes online drilling with pressure, drilling construction is allowed no longer to need
It waits, improves the convenience of construction, by the special equipment, may be implemented to drill at any time；Metal fragment after drilling is not
The pollution sources of production gas can be become, and be directly discharged by escape orifice, it is ensured that during drilling, a small amount of pressure medium
Leakage will effectively be discharged；Positioning ring limits long drill bit shift position, it is ensured that the safety of construction.
