Abstract

The utility model discloses a quick-connection red copper pipe fitting and relates to a pipeline connection part. The quick-connection red copper pipe fitting comprises a red copper pipe body, lower retaining rings, upper retaining rings, pipe disassembly rings, O-shaped rings, stainless steel clamping springs and gaskets. A first step-shaped cavity and a second step-shaped cavity are formed at each end of the red copper pipe body from outside to inside. A gasket is arranged on the inner side of each second cavity, and one to two O-shaped rings are arranged on the outer side of the gasket. The lower retaining rings are arranged on the inner sides of the first cavities, the upper retaining rings are arranged on the outer sides of the first cavities, the stainless steel clamping springs are arranged in the first cavities, edges of the stainless steel clamping springs are clamped between the lower retaining rings and the upper retaining rings, and inner edges of the stainless steel clamping springs are provided with inner teeth. Two pipe disassembly rings are respectively inserted into two ports of the red copper pipe body, and end portions of the pipe disassembly rings are clamped into the inner teeth of the stainless steel clamping springs. According to the quick-connection red copper pipe fitting, the problems that the existing pipeline connection part wastes time and labor in installation, cannot be used repeatedly, and has high requirements for professional standards of installation personnel are solved.

Description

Red copper quick-acting pipe spare

Technical field

The utility model relates to pipeline connecting parts.

Background technique

There is following shortcoming in present pipeline connecting parts: 1. during installation fee, effort; 2. can not reuse; 3. the professional standards to installation personnel require high.

The model utility content

The utility model provides a kind of red copper quick-acting pipe spare, when the utility model has solved the installation fee that existing pipeline connecting parts exists, effort; Can not reuse; To the demanding problem of the professional standards of installation personnel.

For addressing the above problem, the utility model adopts following technological scheme: red copper quick-acting pipe spare, by red copper body 1, time retaining ring 2, last retaining ring 3, imperial pipeloop 4, O type circle 5, stainless steel jump ring 6 and pad 7;

Said red copper body 1 two ends are step-like first die cavity 1-2 and second die cavity 1-3 from inwardly having outward; The diameter of first die cavity 1-2, second die cavity 1-3 and red copper body 1 reduces successively, and first die cavity 1-2 port edge periphery has inside closing in along 1-1;

Be provided with a pad 7 second die cavity 1-3 inboard, pad 7 arranged outside have one to two O type circle 5;

Be provided with retaining ring 2 down in first die cavity 1-2 inboard, first die cavity 1-2 arranged outside has last retaining ring 3;

In first die cavity 1-2, be provided with stainless steel jump ring 6, stainless steel jump ring 6 edges are sandwiched in down between retaining ring 2 and the last retaining ring 3; There is internal tooth 6-1 the inside edge of stainless steel jump ring 6;

Two imperial pipeloops 4 are inserted in respectively in red copper body 1 two-port, drive pipeloop 4 ends and are stuck among the internal tooth 6-1 of stainless steel jump ring 6.

The utlity model has following advantage: 1. tool free when installing, need not sealing strip, need not welding, plug and play; 2. it is convenient to change, and make that the maintenance pipeline is simpler, and pipe fitting can be repeatedly used; 3. install and need not the patent personnel, anyone can accomplish safely; 4. this product can use in pipeline more than 70 years, and the joint sealability is reliable.

The utility model can be widely used on the various pipelines, like copper pipe, iron pipe, Stainless Steel Tube, pvc pipe, on the pipelines such as UPVC pipe.Can reach 70 years working life.Product can be according to the country variant standard-required, corresponding different sizes and the specification processed.

Symbol description among the figure: red copper body 1, close up along 1-1, first die cavity 1-2, second die cavity 1-3, down retaining ring 2, go up retaining ring 3, drive pipeloop 4, O type circle 5, stainless steel jump ring 6, internal tooth 6-1, pad 7.

Embodiment

With illustrated embodiments the utility model is done detailed explanation below.

As shown in Figure 1, red copper quick-acting pipe spare is by red copper body 1, time retaining ring 2, last retaining ring 3, imperial pipeloop 4, O type circle 5, stainless steel jump ring 6 and pad 7;

The utility model installation method: the red copper body that will be pressed into definite shape; In second die cavity, load onto pad earlier; Adorn two O-type circles above the pad; Just in time the height with second die cavity is the same with pad for O-type circle, like this can be so that load in order at first die cavity: following retaining ring, stainless steel jump ring, go up retaining ring, drive pipeloop after, prolong the limit of red copper body tightly last retaining ring pinning with riveter.So just organically be contained in each parts the jointing of red copper body.If the red copper body has a plurality of interfaces, just need these parts respectively after each jointing is loaded onto, be riveted on one by one on the red copper body.

Be used for closed conduit with O-type circle, the stainless steel jump ring is used for pinning pipeline.Driving pipeloop then is when above pipeline, taking off pipe fitting, and when in body, pressing it with special tool, masterpiece is used on the internal tooth of stainless steel jump ring, internal tooth is loosened, thereby easily take off pipe fitting, thereby play reusable purpose.

The mode that the utility model adopt speed to insert makes installation, more fast, save time; The sealing means of O type circle makes the sealability of pipeline higher; Imperial pipeloop makes pipe fitting to reuse, and uses more economically, and environment protection significance is big.

What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
