Description
Technical field
The utility model category water tubular union technical field, is related to a kind of water pipe elastic connecting device.
Background technology
In the prior art, traditional metallic water pipe is generally attached by straight coupling, elbow or three-way connection, connection
Mode is in connector termination inwall processing internal thread, and in water pipe termination threading, band is wound on external screw thread, will
Connection is completed in metal tube external screw thread precession connector internal thread.It is that rigidity connects between such connection mode water pipe and water pipe
Connect, be easily damaged leak at the water pipe head that is affected by thermal expansion and contraction, during operation scene need to carry out tapping in water pipe termination, it is necessary to
The instrument of carrying is more, cumbersome, and work efficiency is low.
PVC plastic pipe largely uses in water system with advances in technology, the connection generally use heat of PVC plastic pipe
Molten mode realizes, the plastic tube that connects and pipe fitting joint sleeve will be needed during connection to be inserted into hot-melting tool while heat respectively, made
Its surface melting, fixed, cooling in pipe fitting joint sleeve is inserted into after dissolving by plastic tube, and the company of water pipe is realized by pipe fitting joint sleeve
Connect.This connection mode is also fixed rigid connection, it is necessary to there is power supply in construction site, uses dedicated hot-melting tool ability
Realize connection, water pipe cannot be removed after connection, and installation and maintenance are inconvenient.
The content of the invention
The utility model is directed to when metallic water pipe is connected with plastic water pipe in the prior art using fixed rigid connection side
A kind of the problem of formula, existing needs to use specific purpose tool, and attended operation is cumbersome, installation and inconvenient maintenance, there is provided water pipe elasticity
Attachment device, solves problems of the prior art.
Concrete scheme is：Water pipe elastic connecting device, the connector of the device are installed on the connection between water pipe and water pipe
Position, is provided with sealing ring on the inside of connector termination, and water pipe termination is inserted into sealing ring, is also equipped with the termination of water pipe
Fixing piece, is machined with external screw thread on the outer wall of connector termination, is machined with internal thread in fixing piece front inner wall, internal thread and outer
Screw thread cooperates, and fixing piece rear end is machined with tapered closing in, and being set with band on the water pipe on the inside of the tapered closing in of fixing piece opens
The elastic ferrule of mouth, elastic ferrule outer wall are in tapered, and inwall processing stings ring, and flange is designed with connector inner cavity termination,
Card slot is designed with the middle part of sealing ring, card slot is installed on flange, and sealing ring is machined with sealing ring inner wall.
Connector is straight coupling, elbow, three-way connection or four-way connection.
Using the technical program, by ring set in connector inner cavity termination when water pipe connects, then by fixing piece and bullet
Property cutting ferrule be inserted in successively on water pipe termination, by water pipe termination insertion water pipe connector sealing ring in, water pipe connection end it
Between retain certain interval, sealing ring realizes sealing between water pipe and connector, and the internal thread of fixing piece is screwed in outside connector
On screw thread, the tapered closing in of fixing piece promotes elastic ferrule reach, and elastic ferrule is pressed on water pipe, realize the present apparatus with
Fixation between water pipe.The technical program is suitable for metal tube, is also suitable for the connection of plastic tube, applied widely；
Since sealing ring is elastic packing between connector and water pipe, a small amount of established angle that water pipe is likely to occur when connecting
Degree change, sealing ring can occur corresponding elastic deformation and be adapted therewith, keep the sealing state of whole device；Water pipe installation makes
Used time tube body occurs a small amount of length change or expands with heat and contract with cold, and water pipe termination can be slided on a small quantity in sealing ring, keep
The internal stress of pipeline is reduced in the case that whole system sealing state is constant, the rigid deformation quantity of pipeline is reduced, extends water pipe
Sealing and service life；Without using the specific purpose tools such as tapping or hot melt, worker's installation when this technology connects water pipe at the scene
When it is easy to operate, work efficiency is high；It is machined with the elastic ferrule inner wall of opening and stings ring, is can be very good to sting and fasten in water pipe
On, good fixing effect；The sealing ring processed on the inner wall of sealing ring, can form multiple sealing rings, sealing effect on water wall
Fruit is good.
