Abstract

The utility model discloses a cutting ferrule formula metallic pipe coupling, including casing, nut, sealing washer, plain washer, C type snap ring, sealed recess and thread bottom's step, its characterized in that, the port portion outer wall of casing is the external screw thread, the inner wall is sealed recess, interior thread bottom is equipped with a step, the silica gel sealing washer, plain washer and type snap ring are located between casing and the nut, this cutting ferrule formula metallic pipe coupling installation is convenient, as long as with the nut, the silica gel sealing washer, the plain washer, C type snap ring cover is on the pipeline that specification and dimension corresponds with the joint, then with in the pipeline attachment plug and screw the nut on the casing can, need not not be with the help of any equipment and technique in the installation, thereby certain manpower and materials have been saved, adopt silica gel sealing washer and C type snap ring simultaneously, have good leakproofness and fixity and high pressure resistant, thereby it is very little to make the possibility that takes place the seepage, and the service life of the product is prolonged.

Description

A kind of bite type metallic pipe coupling

Technical field

The utility model is related to a kind of pipeline connection technology, specifically a kind of bite type metallic pipe coupling.

Background technology

Pipe joint in the market is various, has the butt joint of screw-type, collar joint, nonmetallic joint etc..1、 Screw-type joint requires higher to the wall thickness of material, and it is too high to have thus resulted in use cost, and installs trouble, once screw thread dress Join bad, be easy for producing seepage；2nd, collar joint adopts annular seal circle, and non-nonmetallic materials, its fixed performance Difference, and the time is long, the easily generation of nonmetallic sealing ring is aging, will also result in seepage；3rd, nonmetallic joint is carried out using adhering method Connect, be unable to undergo to shake, affected its pressure poor performance by expanding with heat and contract with cold, and the sticky object of abutting edge is apt to deteriorate and old Change, seepage also can occur, in sum, product in the market all has life-span shorter defect.

Utility model content

The purpose of this utility model is to provide a kind of bite type metallic pipe coupling, to solve to propose in above-mentioned background technology Problem.

For achieving the above object, the following technical scheme of the utility model offer:

A kind of bite type metallic pipe coupling, including housing, nut, sealing ring, plain washer, c type snap ring, sealed groove and spiral shell The step of line bottom, the port part outer wall of described housing is external screw thread, and inwall is sealed groove, and internal thread bottom is provided with one Rank, silica gel sealing ring, plain washer and type snap ring are located between housing and nut.

As further program of the utility model: the inwall of described screw thread is to mate with the external screw thread of housing port part Internal thread.

As the utility model further scheme: the angle of the lateral surface of this silica gel sealing ring and the inboard wall groove of housing Degree is consistent, highly consistent, typically takes 2.5-3.5mm, is mutually matched.

As the utility model further scheme: the internal diameter cone of the external diameter of described c type snap ring and bottom of thread step Shape is mated, highly for 2.0-2.5mm.

Compared with prior art, the beneficial effects of the utility model are: this bite type metallic pipe coupling install convenient, as long as Nut, silica gel sealing ring, plain washer, c type snap ring are enclosed within specification pipeline corresponding with joint, then pipeline are inserted In joint and nut is screwed on housing, need not be by any equipment and technology, thus saving one in installation process Fixed manpower and materials, adopt silica gel sealing ring and c type snap ring simultaneously, have good sealing and stationarity and high pressure resistant, from And make generation seepage possibility very little, extend the service life of product.

Brief description

Fig. 1 is the structural representation of bite type metallic pipe coupling.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of the utility model protection.

Refer to Fig. 1, in the utility model embodiment, a kind of bite type metallic pipe coupling, including housing 1, nut 2, close Seal 3, plain washer 4, the step 7 of c type snap ring 5, sealed groove 6 and the bottom of thread, the port part outer wall of described housing 1 is outer spiral shell Line, inwall is sealed groove 6, and the inwall of described screw thread 2 is the internal thread mating with the external screw thread of housing 1 port part, internal thread Bottom is provided with a step 7, and silica gel sealing ring 3, plain washer 4 and c type snap ring 5 are located between housing 1 and nut 2, this silica gel sealing The lateral surface of circle 3 is consistent with the angle of the inboard wall groove of housing 1, and highly consistent, generally 2.5-3.5mm is mutually matched, c type The external diameter of snap ring 5 is mated with the internal diameter taper of bottom of thread step 7, a height of 2.0-2.5mm.

During installation, as long as nut 2, silica gel sealing pad 3, plain washer 4 and c type snap ring 5 are enclosed within specification and joint pair Then pipeline should be inserted in joint, nut 2 screwed on housing 1 on pipeline, pipeline and joint install with Afterwards, the pipeline in insertion connection port is stretched out to a certain degree, experiment results proved, joint pressurized place ne-leakage, and seal Circle pulling force characteristic improves 10%, and this function compensate for some pipelines in the market once has micro stretching will produce seepage Defect.

This bite type metallic pipe coupling install convenient, as long as nut, silica gel sealing ring, plain washer, c type snap ring are enclosed within rule On lattice size pipeline corresponding with joint, then pipeline is inserted in joint and nut is screwed on housing, installed Silica gel sealing ring and c type card need not be adopted by any equipment and technology, thus saving certain manpower and materials in journey simultaneously Ring, has good sealing and stationarity and high pressure resistant so that occur seepage possibility very little, extend product Service life.

It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limiting Involved claim.

Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of specification Using specification as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined Understandable other embodiment.
