Abstract
The present invention relates to a kind of pipe connection, including pipe union, pipe-connecting nut and clamp ring, in which the pipe-connecting nut possesses several uniformly-distributed lugs on the cone surface between the internal screw of its screw-connecting portion and internal ring surface of rear ring portion, and the periphery of the clamp ring also is equipped with a slot cut-in from one side, and the chamfered portion opposite the cut-in opening of said slot possesses a narrow connecting flange, so that in the course of installation the clamp ring can be contacted with lugs of pipe-connecting nut to reduce their relative contact area and friction force, and reduce labour strength, and the same time the slamp ring also possesses connecting flange so as to implement correct installation, and insert the pipe into pipe connection.
Description
The present invention relates to a kind of pipe coupling, refer to a kind of pipe connector of being convenient to install and compress connected pipe especially.
At present, traditional pipe connector has been widely used in by the plastic cement pipe, has contained the composite pipe of metallic material, for example in the connection of pipeline such as aluminium plastic composited tube or pipe.This pipe connector is mainly by pipe joint (main body), nuion nut, retainer ring are formed, wherein, nuion nut has the chamfering of handing-over or changeover portion-promptly be the conical surface between the inner ring surface of the internal thread of its spiro union portion and back ring portion, and retainer ring is generally the unconnected ring with an inclined slot.When mounted, headgear at a pipe is put nuion nut and retainer ring, pipe this is inserted in the pipe joint again, be screwed to nuion nut on the pipe joint in advance, simultaneously retainer ring is clipped between the end and nuion nut of pipe joint, then, further tighten the pipe nut, retainer ring tightly is pressed on the pipe with spanner.But in the process that nuion nut is tightened, a side of retainer ring is rotated contact mutually with the chamfering conical surface of nuion nut, produces big frictional resistance, so increased working strength of workers greatly.On the other hand, retainer ring is made by brass usually, because it is unconnected ring, so all be easy to make its distortion in transportation, carrying and installation process, therefore, can not be nested into easily on the pipe, causes to install to interrupt or pause; The distortion of retainer ring causes that also it departs from mounting center, and can not effectively compress pipe, not only makes the decline of labour productivity but also installation quality is degenerated.
The objective of the invention is to provide a kind of nuion nut to be easy to tighten and retainer ring can accurately be enclosed within the pipe connector of pipe and centering with pipe joint in order to overcome above-mentioned defective.
The technological scheme that realizes above-mentioned purpose is: a kind of pipe connector, comprise have externally threaded pipe joint, by spiro union portion and back ring portion nuion nut, the retainer ring formed, wherein, described nuion nut is provided with some uniform projections on the conical surface that is had between the inner ring surface of the internal thread of its spiro union portion and back ring portion.
Pipe connector as previously discussed, wherein, the both side edges car of described retainer ring has chamfered section, also is provided with one on its side face from cracking that a side is cut, and leaves a narrow fillet on the relative chamfered section of this entry of cracking.
Pipe connector as previously discussed, wherein, the both side edges car of described retainer ring has chamfered section, is provided with a strip gab on its side face, respectively leaves a narrow fillet on the chamfered section of the both sides of this opening.
Pipe connector as previously discussed, wherein, described retainer ring is made up of a middle internal ring portion, two the cone-shaped joints of outer portion and two between internal ring portion and outer portion in both sides, on its side face, be provided with one from cracking that a side is cut, on the relative outer portion of this entry of cracking, leave a narrow fillet.
Pipe connector as previously discussed, wherein, described retainer ring is provided with a strip gab on its side face, respectively leaves a narrow edge joint limit on the outer portion of these opening both sides.
Pipe connector as previously discussed, wherein, described projection is the raised line shape, its true dip direction is parallel to the awl line direction of the conical surface.
Pipe connector as previously discussed, wherein, the axis with relative each retainer ring of opening of cracking of described retainer ring is with the α angle tilt, and α is 15～45 °.
Pipe connector as previously discussed, wherein, described α is 30 °.
Therefore, the present invention is by being provided with projection and leaving fillet at retainer ring in the relative side of the opening that cracks on the transition layer in the butt tube nut, perhaps leave fillet in the opening both sides of retainer ring, tightening in the pipe joint process and make at union nut, retainer ring contacts with the projection of union nut, it is long-pending to reduce relative contact, reduce friction, and labor strength is reduced greatly, simultaneously, continue to employ fillet on the one or both sides of retainer ring, make in carrying and the installation and can not be out of shape, correctly centering is convenient to pipe and is inserted on the pipe joint certain position by retainer ring, can save the installation time, raise labour productivity and guarantee the installation quality of pipe connector and pipe.
