Description
Technical field
The present invention relates to the clips of pipeline connection, and in particular to a kind of pipeline connects clip fastly.
Background technique
Currently, pipeline connects clip because its is easy to use, connection speed is fast fastly, it is widely used in the connection of pipeline.It is existing
It includes in semiorbicular two clip ontologies that pipeline connects clip fastly, and the both ends of the clip ontology are respectively provided with for receiving screw thread to connect
The lug of fitting, radial convex is equipped at intervals on the inner ring surface of the clip ontology and two along the circumferentially extending of inner ring surface are convex
Muscle, the inner ring surface are equipped with the seal groove between the convex ribs；Two clip ontologies can be by passing through the lug
Bolt is end-to-end to link together；Can be crossed after two clip ontology end-to-end links the central space for receiving pipeline and
The sealing ring in seal groove is equipped in the central space.
The pipeline of above structure connects clip fastly and is primarily present following defect: first is that, the slot bottom of seal groove and convex ribs it is interior
The distance between anchor ring is groove depth, and depth of the groove depth from the middle part of clip ontology to both ends is identical；Since pipeline connects clip fastly
The outer perimeter of sealing ring be greater than the sum of the length of seal groove of two clip ontologies, two clip ontologies are assembled together
Afterwards, end will appear interval, and when hoop sleeve is fastened on pipeline, sealing ring compressive deformation can be prominent from interval
Come, easily cause section corresponding to the protruding portion of sealing ring and tube contacts bad, and leads to seal failure.Second is that sealing ring
Ontology on be connected with retaining ring, since the ontology of the retaining ring and sealing ring is solidly fixed, retaining ring can hinder close when locked clip device
The free shrink of seal causes sealing ring and retaining ring to form undulatory out-of-flatness, and with the aging of sealing ring, retaining ring meeting
Band dynamic seal ring is shunk inwards, is bonded together the ontology of sealing ring and ring lip, to lose the effect of self-sealing, is caused close
Envelope failure.
Summary of the invention
The technical problem to be solved in the present invention first is that in view of the foregoing drawbacks one, a kind of pipeline is provided and connects clip fastly, the card
Sealing ring is not easy outstanding from the interval of two clip ontologies when band tightener, and avoidable sealing ring is bad with tube contacts and leads
The seal failure of cause.
It in order to solve the above technical problems, the present invention provides a kind of pipelines such as flowering structure to connect clip fastly, including is in semi-ring
Two clip ontologies of shape, the both ends of the clip ontology are respectively provided with the lug for receiving threaded connector, the clip sheet
Radial convex and two convex ribs along the circumferentially extending of inner ring surface are equipped at intervals on the inner ring surface of body, which, which is equipped with, is located at
Seal groove between the convex ribs；Two clip ontologies can be connected to one by what to pass through the bolt of the lug end-to-end
It rises；It can cross to be equipped in central space and the central space for receiving pipeline after two clip ontology end-to-end links and be mounted in
Sealing ring in seal groove；Its design feature is: between the slot bottom of the seal groove and the inner ring surface of the convex ribs
Distance is groove depth；The groove depth is maximum, minimum in the end of clip ontology at the middle part of clip ontology.
The middle part of the groove depth from clip ontology is gradually reduced to both ends.
The inner ring surface of the seal groove and the convex ribs is arranged concentrically.
Groove depth is set as maximum in the middle part of clip ontology, is set as minimum in the end of hoop ontology by the present invention, is fastened in this way
When clip, after sealing ring compressive deformation its deformation surplus can from the end of hoop ontology to clip ontology in the middle part of collect, do not allow
Easily there is a phenomenon where after sealing ring compressive deformation between the end of clip ontology it is outstanding, sealing ring and pipeline can be effectively ensured
Come into full contact with, can guarantee sealing effect.
The second technical problem to be solved by the present invention is in view of the foregoing drawbacks two, based on the above technical solution into one
Step takes following proposal:
The sealing ring includes cushion rubber ontology, and the both ends of cushion rubber ontology are respectively provided with to be linked together and centre is set with cushion rubber ontology
Have an end wall of axially extending bore, the end wall inward flange axis inwardly convexes into ring lip, the sealing ring further include not with cushion rubber ontology
The retaining ring being directly linked together.
The retaining ring is two and is connected on two ring lips.
Ring sets multiple convex blocks on the inner wall of the cushion rubber ontology, and the convex block is equipped with socket, and the retaining ring is inserted into
In the socket.
Guide sleeve is connected on the inner ring surface of the retaining ring.
Loop connecting body is fitted between the cushion rubber ontology and ring lip, the hollow setting of loop connecting body forms ring
Chamber offers opening along its circumferential direction on the outer ring surface of loop connecting body, and the retaining ring is connected on the inner ring surface of loop connecting body.
Multiple liquid pass holes are equipped on the inner ring surface of the retaining ring, the liquid pass hole is connected to the ring cavity.
Retaining ring is not linked together directly by the present invention with cushion rubber ontology, and retaining ring not only plays position-limiting action, but also will not be in card
The free shrink that sealing ring is hindered when hoop locking, causes sealing ring and retaining ring to form undulatory out-of-flatness, and with sealing
The aging of circle, retaining ring will not be shunk inwards with dynamic seal ring, and the ontology and ring lip for avoiding sealing ring are bonded together and lose
The effect of self-sealing and cause seal failure.
