Description
Technical field
The present invention relates to a kind of attachment devices, and in particular to a kind of pipe connector lug.
Background technique
Union is a kind of common conduit coupling that can facilitate installing and dismounting as a kind of connecting pipe, is widely applied
It is connected in the pipeline of multiple industries such as feedwater piping, gas pipeline.Union generally by nut, cloud cluster, flush three part groups
It at, cloud cluster and flushes for two segment pipes in connecting pipe, cloud cluster peace is connect and connected by intermediate nut, facilitates two sections
The connection and disassembly of pipeline, are easily installed and overhaul.But this requires the distance between two segment pipes of connection, if two
The distance between segment pipe is excessive, then will lead to cap nut cannot screw and cause to seal bad；If between two segment pipes
Apart from too small, then pipeline can bend, not applicable in the limited position in Pipe installing space.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problems to be solved by the present invention are: how to provide a kind of install fastly
Speed is convenient, the good pipe connector lug of sealing effect.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:
A kind of pipe connector lug passes through screw rod between two and half bodies including closing up the connector sleeve formed by two and half bodies
It is fixedly connected, the diameter of bore of connector sleeve is greater than the outer diameter to connecting pipe, the inner hole of connector sleeve and the position for being located at its both ends
It is respectively arranged with connection screw thread, the both ends along its centerline direction of connector sleeve are respectively arranged with installation set, the internal diameter of installation set
With the crest clearance cooperation to connecting pipe, the outer surface of installation set is extended with by one end to the other end along its centerline direction
Installation screw thread, installation set is made of the straightway and reducer being coaxially disposed, and the outer diameter of reducer is along its centerline direction court
It is gradually increased to far from straightway direction, the connection that the one end of straightway far from reducer passes through installation screw thread and its side
It is threadedly engaged so that installation set is fixed on connector sleeve, is also arranged with and is threadedly coupled with it with can be along connector sleeve on straightway
The locking nut that the rotation of heart line direction moves, is provided with a plurality of along reducer length direction on reducer and around its center line uniform intervals
The strip shape gob of the other end is extended to by one end, is provided at strip shape gob and is extended to along strip shape gob length direction by strip shape gob one end
The elastic rubber strip of the other end, elastic rubber strip is Nian Jie with strip shape gob and sealing cooperates, when locking nut is straight greatly towards reducer
When the rotation of diameter extreme direction moves, locking nut can squeeze reducer so that reducer is treated connecting pipe and is clamped, and
And reducer can squeeze to bring it about flexible deformation and be connected to wait connect the elastic rubber strip being located at strip shape gob
On pipeline.
In the present invention, when use, first two installation sets are covered at two in connecting pipe respectively, two of them
Straightway in installation set is opposite, then on pipeline, and is threaded on straightway by locking screw mother set, then by two
The corresponding position between two root canal roads of a half body closes up fixation and forms connector sleeve, makes one end difference position that two root canal roads are opposite
In the inner hole of connector sleeve, the installation set at connector sleeve both ends is then passed through into installation screw thread on wherein straightway and connector sleeve
Connection screw thread is connected, and such installation set is secured on connector sleeve, is then rotating two locking nuts respectively, is making its direction
Reducer direction is mobile, and when mobile, the inner hole of locking nut squeezes reducer, carries out reducer to pipeline
It clamps, clamping degree is stronger, and leakproofness is stronger, while when reducer is clamped pipeline, can be to positioned at strip shape gob
The elastic rubber strip at place is squeezed, and makes elastic rubber strip that flexible deformation occur to be connected on pipeline, together towards duct orientation
Sample reducer is stronger to pipeline clamping degree, and the leakproofness between elastic rubber strip and pipeline is stronger.Not only make two in this way
Pipeline links together, while the connection sealing effect between two root canal roads is also very good, additionally mounted also quick and convenient.
As optimization, around the connector sleeve center line in the inner hole of the connector sleeve and respectively close to the position in its both ends
A circle baffle ring is convexed to form, the internal diameter of baffle ring is consistent with the internal diameter of the installation set, and the connection screw thread is along the connector sleeve
