Abstract

A kind of novel socket fitting linkage structure, is applicable to the interconnection technique of PVC plastic pipeline.Novel socket fitting linkage structure described in the utility model is made up of socket pipe member (1), grafting pipe fitting (2), O RunddichtringO (3); Wherein the oblique angle enlarging (5) having≤25 ° is expanded in the port, one end of socket pipe member (1); The upper one end of grafting pipe fitting (2) is provided with Baltimore groove (4), and O RunddichtringO (3) is mounted in Baltimore groove (4).Grafting pipe fitting (2) is inserted in the oblique angle enlarging (5) of socket pipe member (1) port, just can reach two close-connected objects of pipe fitting.Pipe fitting joint structure described in the utility model, Joining Technology is easy, is easy to remove and repair, and fabricating cost is low, good sealing effect.Use the potential safety hazard that all can effectively prevent pipe leakage, gas leakage etc. from producing under various environmental conditions, substantially increase the working life of pipeline.

Description

A kind of novel socket fitting linkage structure

Technical field

The utility model belongs to technical field of pipeline connection, relates generally to a kind of novel socket fitting linkage structure.

Background technique

In PVC plastic pipeline connection technology, bayonet joint mode, with the flexibility characteristics of its uniqueness, makes the pipeline after connection have the ability of anti-vibration, resisted shrinkage and expansion.Bayonet joint and flange-type connect to connect with clamp band type to be compared, and the pipeline structure stability of a system after connection increases, and is more applicable to the change of ambient temperature, thus decreases the destruction of pipe stress to structural member.In recent years in PVC plastic pipeline connection technology, bayonet joint technology was widely applied at home, was mainly used in water drainage-supply system or small part rigid conduit.At present, the bayonet joint technology mainly straight socket joint method adopted in PVC plastic pipeline connects, the mode of smearing Bond at jointing connects, and the advantage of above-mentioned Placement is: easy for installation, quick, the duration is short, and has certain antihunt action.But by the linkage structure that above-mentioned Placement is formed; too large problem is there will not be in conventional working environment; but use in hyperbaric environment condition and pipeline just often can occur deviate from; cause leaking, leaking gas; produce potential safety hazard, have a strong impact on safety in production, and owing to adopting Bond to be connected and fixed between pipeline; be difficult to dismounting, cause keeping in repair.

Model utility content

For problem existing in prior art, the utility model proposes and disclose that a kind of Joining Technology is easy, pipe fitting expanding socket type connecting structure that good seal performance, connection are safe and reliable, to overcome the deficiency in prior art in straight socket joint method interconnection technique.

For realizing above-mentioned technical purpose, the concrete technological scheme that the utility model adopts is: a kind of novel socket fitting linkage structure, is made up of socket pipe member, grafting pipe fitting, O RunddichtringO; Wherein the oblique angle enlarging having≤25 ° is expanded in the port, one end of socket pipe member; One end on grafting pipe fitting is provided with Baltimore groove; O RunddichtringO is mounted in the Baltimore groove of grafting pipe fitting; Grafting pipe fitting is connected with socket pipe member by oblique angle enlarging; The novel socket fitting linkage structure of described one, wherein grafting pipe fitting fovea superior shape slot is put and is arranged on 1/2nd places that grafting pipe fitting inserts the oblique angle enlarging degree of depth; The novel socket fitting linkage structure of described one, wherein socket pipe member and grafting pipe fitting are polychloroethylene pipes.

The novel socket fitting linkage structure of one described in the utility model, its Joining Technology is easy, is easy to remove and repair, and cost is low, and sealing effect is better than the linkage structure of prior art.Use the appearance that all effectively can prevent the problem such as pipe leakage, gas leakage under various environmental conditions, avoid producing potential safety hazard, substantially increase the working life of pipeline.

Embodiment

Mode of execution of the present utility model is provided as follows below in conjunction with accompanying drawing:

As shown in Figure 1, Figure 2, Figure 3 shows, the novel socket fitting linkage structure of one described in the utility model, is formed by adopting the socket pipe member 1 of polychloroethylene pipes making and grafting pipe fitting 2 and O RunddichtringO 3; Wherein the oblique angle enlarging 5 having≤25 ° is expanded in the port, one end of socket pipe member 1; On grafting pipe fitting 2, one end is provided with Baltimore groove 4; O RunddichtringO 3 is mounted in the Baltimore groove 4 of grafting pipe fitting 2; The operative position of Baltimore groove 4 on grafting pipe fitting 2 is 1/2nd places that grafting pipe fitting 2 matches with socket pipe member 1 one end port oblique angle enlarging degree of depth.When socket pipe member 1 is connected with grafting pipe fitting 2, first uses the tube wall of heating equipment to socket pipe member 1 one end port to carry out enlarging heating, expand the oblique angle enlarging 5 to≤25 °, re-use mould shape.O RunddichtringO 3 is mounted in the Baltimore groove 4 on grafting pipe fitting 2, and then grafting pipe fitting 2 is inserted in the oblique angle enlarging 5 of socket pipe member 1, after socket pipe member 1 cools completely, just reach two close-connected objects of pipe fitting.
