Description
Technical field
Pipe fitting plugging structure technical field is the utility model is related to, specially a kind of plastic union pipe head seal.
Background technology
Seal be prevent fluid or solia particle from leak and prevent between adjacent faying face introduced contaminants such as dust with
The material or part of parts inside the intrusion machinery equipment such as moisture.The storage room temperature of seal is kept away preferably below 30 DEG C
Exempt from seal and produce high temperature ageing.Pipe joint has easy for installation, superior performance, service life length and other effects, is widely used in
In the construction of the water supply and sewage cause in field such as water supply, draining, electric power, metallurgy, urban construction, oil, each large and medium-sized enterprise of chemical industry environmental protection.
But some drawbacks in use be present in traditional pipe fitting joint sealing, such as：
1st, rare seal at traditional pipe fitting joint, pipeline is so caused to need the situation of temporary enclosed tackling some
Shi Wufa completes closure work, brings some influences for work, and existing seal uses metal seal more, causes to seal
Corrosion easily occurs in the case where long-time seals and is bonded together with pipeline for part, can not reuse.
2nd, traditional conduit seals can only play a part of sealed pipe fittings head, but needed when enabling pipeline again by
Existing pipeline is closely connected with new pipeline, then at this moment just needs to use new pipe joint to connect two segment pipes, compare expense
Power.
The content of the invention
The purpose of this utility model is to provide a kind of plastic union pipe head seal, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of plastic union pipe head seal, including
Closure, ring flange, connecting tube, sealing block, the connection inside pipe wall center are fixedly welded with barrier circle, described connecting tube one end
External stability is welded with ring flange, and the connection inside pipe wall, which is located between ring flange and barrier circle, is fixedly installed the first connection
Mouthful, the first connector inwall, which is fixed, offers the first internal thread, and the barrier circle fixes peace close to the first connector side
Equipped with the first sealing ring, the second connector is fixedly installed away from first connector one end inside the connecting tube, described second
Fixed inside connector to offer the second internal thread, the barrier circle is installed with second close to the second connector side
Sealing ring, the closure inside center are fixedly connected with sealing block, and the sealing block outer wall is by interior second screw thread with being connected
Pipe screw thread connects.
Further, the flange plate edge uniform screw thread is connected with fastening screw.
Further, the closure is socketed in connecting tube to be located at the second connector institute outside at one end.
Further, the closure external activity is provided with adapter sleeve, and the adapter sleeve external stability is provided with fastening
Button.
Further, the closure, which is internally located at around sealing block, is installed with sealing gasket.
Compared with prior art, the beneficial effects of the utility model are：
1st, by by closure using polyethylene manufacture, because polyethylene has advantageous inoxidizability, even if with pipe
Road combines for a long time, will not also cause pipeline to occur with the situation that seal is bonded together, and polyethylene material is with good
Toughness, it can be closely fixed together with pipeline by adapter sleeve, increase sealing property.
2nd, by the way that fixation offers the first connector and the second connector respectively at connecting tube both ends, it is easy to user by the
One connector is fixedly connected with pipeline, the installation end using the second connector as seal, when user need not enter to pipe fitting
Row sealing, which makes to remove closure, to facilitate the connection of pipeline to install by new Pipe installing in the second connector.
