Description
Technical field
The utility model relates to recanalization technical field, in particular to a kind of metal latch immediately pipe device.
Background technique
It plugs into field in existing pipeline, card convex type connection is most commonly seen attachment device.Card convex type connection is convex
Ring rectangular triangle or arc-shaped, sealing ring use end face seal mode, have a conical seal ring at screw thread, by screw thread
To the connection type of the extruding sealing of conical seal ring.Its Connection Step includes: tube length needed for 1. in-site measurements and carries out
Interception；2. expanding bulge loop with pipe of the dedicated expansion bulge loop machine to interception, pipe should be inserted into the upper roll wheel end of bulge loop machine when expanding bulge loop
Inner plane is close in face, and makes tube axis parallel with roller axis；3. being changed hands by the compression expanded on bulge loop machine to tube wall
Slowly pressurization, gradually protuberance one encloses bulge loop to pipe outward；4. expanding bulge loop machine has been provided with bulge loop limit height and width, bulge loop is confirmed
The back spin that is of the required size loosening pressure is tightly changed hands, and exits pipe from expanding on bulge loop machine upper roll wheel.
It is larger due to expanding bulge loop body product, and price is relatively high, therefore only sole duty carries out applying for pipeline connection engineering
Crew can just purchase.And general user expands bulge loop machine due to lacking, so not being available card convex type connects pipeline of voluntarily plugging into.
Utility model content
Place to solve the deficiencies in the prior art, the utility model provide a kind of metal latch immediately pipe device, use
The sealing and locking that similar principle removes realization recanalization are connected with card convex type, but expands bulge loop machine pair without relying on again simultaneously
The processing of pipe, so that general user also can voluntarily complete recanalization.
A kind of metal latch immediately pipe device, including to connecting tube, left connector, right connector and lock ring, the left company
Fitting and right connector are socketed with to connecting tube, and to be threadedly coupled between left connector and right connector, the lock ring
For standard revolving body, section includes bottom edge, top margin, left contact edge and right contact edge, the lock ring formed by the bottom edge
Inner wall is adapted with the outer wall to connecting tube, and the top margin is abutted with the inner wall of left connector or right connector, the left contact
Side and/or right contact edge and bottom edge form acute angle α, and the left connector has left compressing end face, the left compressing end face
The surface formed with the left contact edge in lock ring section is interference fitted, and the right connector has right compressing end face, the right pressure
The surface for compeling the right contact edge formation in end face and lock ring section is interference fitted.
Further, the left compressing end face and/or right compressing end face form acute angle β, the angle β with to connecting tube
Greater than angle α.
Or the inner wall of the lock ring is equipped with groove.
Further, sealing ring is equipped in the groove.
When the inner wall of lock ring is equipped with groove, the left compressing end face and right compressing end face are vertical with to connecting tube.
Further, the sealing ring is one of Teflon member, EPDM component or silica gel component.
Metal latch disclosed by the utility model immediately pipe device, by adding lock ring, to enable without expanding bulge loop machine
Also being capable of forming to connecting tube for processing is similar to bulge loop used in card convex type connection.Simultaneously because on lock ring at least
Side is wedge structure, therefore it can be due to interference fit during left connector and right connector are threadedly coupled locking
Reason and deformation occurs, and then be embedded in connecting tube, good sealing effect can be played.
