Abstract
The utility model discloses a kind of steel ring skeleton framing built-in type rubber packing ring for plastic pipe, it includes rubbery sealed body and the steel ring skeleton being placed in rubber seal body, and the cross section of steel ring skeleton is hexagon.The utility model good airproof performance, the discharge pressure that can be born are high, simple installation is reliable, scrappage is low, ensures that built-in steel wire is indeformable in negative pressure and cushion rubber does not leak.
Description
Technical field
The utility model is related to technical fields, and in particular to a kind of steel ring skeleton framing built-in type rubber packing ring for plastic pipe.
Background technology
The effective rubber seal of plastics is mainly used in pipeline：Sealability is provided under pressure state, avoids conveying
Liquid pipeline junction leak；Under pressure state or normal pressure change in the case of, tubing occur in itself length and
The variation of diameter, at this time tubing should be able to freely stretch in flexible bellmouth and diametric a small amount of breathing.
Existing rubber seal adds after tubing bore thermo forming, then adds plastic cement skeleton branch
Support is fixed, and due to manufacture factor, the size of each rubber seal can not possibly be just the same, such rubber seal and its
Implantation bellmouth mode has the following disadvantages：1st, when rubber ring outer diameter is smaller, bellmouth inner wall cannot with rubber seal ring outer wall
Fully fitting, leads to the increase of slip under pressure state.2nd, when rubber ring outer diameter is bigger, it can not be implanted into bellmouth at all
In, its outer wall can not be bonded at all with tubing mouth inner wall after implantation, and partial rubber circle can inwardly be heaved due to natural resiliency, cause
Rubber ring scrappage is high, difficult to install that easily rubber ring is supported away and destroyed, so that the increase of leakage.
The built-in rubber seal of plastic tube steel-wire carcass in long-term use, it is found that the effect of steel-wire carcass is especially heavy
Will, in pipeline normal operation water flowing, hydraulic pressure does not leak built-in steel-wire carcass rubber seal rising, but actually using
In can often be cut off the water, pipeline is just also easy to produce negative pressure, so as to cause built-in steel wire deform, cushion rubber leakage.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and it is built-in to provide a kind of effective steel ring skeleton of plastics
Rubber seal, good airproof performance, the discharge pressure that can be born are high, simple installation is reliable, scrappage is low, it is built-in in negative pressure to ensure
Steel wire is indeformable and cushion rubber does not leak.
The purpose of this utility model is achieved through the following technical solutions：
Steel ring skeleton framing built-in type rubber packing ring for plastic pipe, it includes rubbery sealed body and is placed in rubber seal body
Steel ring skeleton, the cross section of the steel ring skeleton is hexagon.
Preferably, the rubbery sealed body is equipped with first time moisture seal portion and second of moisture seal portion.
Preferably, second of moisture seal portion is hemispherical projections.
Preferably, the cross section of the steel ring skeleton is regular hexagon.
The beneficial effects of the utility model are：
1st, in the secondary thermo forming of tubing mouth, at the same the rubber seal of steel ring skeleton built in implantation, its technique
Process is that tubing first heats processing special built-in rubber sealing ring in special bellmouth equipment and puts into mold, by thrust that tubing is soft
Property bellmouth heave part, and the inner wall that tubing is heaved is to be molded completely according to rubber ring outer wall shape, it is ensured that between the two tight
It is close, its leakproofness will not be influenced because of the size factor of rubber ring.
2nd, built-in steel wire, replaces additional skeleton, and function of wire is：Rubber ring is supported to keep original shape.Ensure rubber
When circle implantation bellmouth and tubing are inserted into bellmouth, the deformation of each section that rubber ring is contacted with tubing in the circumferential evenly, together
When reaction force and tubing it is vertical in the circumferential also evenly, when ensure that water of the female portion under Pipeline transport pressure state
Uniform force in circumferential direction is broken caused by circumferential unbalance stress during so as to effectively prevent Pipeline transport pressure fluid
It is bad, act on pressure it is higher when become apparent；Position of the fixed rubber ring in bellmouth, being inserted into bellmouth or pipeline in tubing has
When internal pressure leads to pipe length harmomegathus, due to the relationship of frictional force, rubber ring has the tendency that moving together with tubing, built-in steel
The effect of silk skeleton at this time is to increase the intensity of rubber seal, prevents the movement of rubber ring, ensure tubing in junction
It freely stretches and a small amount of diameter change.
3rd, built-in steel ring skeleton is employed, intensity is higher than plastic skeleton, and enables the intensity of entire rubber seal
It improves, bearing higher pressure in pipeline operation will not leak, good airproof performance.
4th, this rubber ring position cross sectional shape in pipeline becomes half-circle projection shape from former triangle pressure protrusion, this
Sample protrusion water shutoff position is upon compression with the contact surface bigger of tubing, the pressure bigger that can be born, and sealing performance is more preferable.
5th, easy installation and reliable, scrappage is low.
6th, it from the point of view of the service condition under different regions, landform, different positive pressures, negative pressure, was never produced according to 2 years
Leakage was given birth to, has the advance and reliability being used for a long time.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is steel ring skeleton structure schematic diagram；
Fig. 3 is the utility model scheme of installation.
Specific embodiment
The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
Such as Fig. 1 ~ 2, steel ring skeleton framing built-in type rubber packing ring for plastic pipe, it includes rubbery sealed body 1 and is placed in rubber
Steel ring skeleton 2 in seal 1, the cross section of the steel ring skeleton 2 is regular hexagon.The rubbery sealed body 1 is equipped with the
Moisture seal portion 3 and second of moisture seal portion 4.Second of moisture seal portion 4 is hemispherical projections.
Such as Fig. 3, when two tubing connect, rubber seal is installed at bellmouth inner wall 5.
Preferably, when selection makes steel ring skeleton 2, selection matter is 65Mn carbon constructional quality steels, and intensity is high, quenching degree compared with
Greatly, decarburizing tendency is small, indeformable using normalized treatment, the performance of 65Mn carbon constructional quality steels, steel ring skeleton 2 built in satisfaction
Usability.
