Description
Technical field
The present invention relates to connectors, and in particular to polythene composite piping connector and matched polyethylene are compound
Pipe.
Background technique
Polyethylene compound pipe is polymerized by monomer ethylene, due to polymerization when because of the polymerization reactions item such as pressure, temperature
Part is different, can obtain the polyethylene of different densities.When processing different type PE tubing, according to the difference of its application conditions, choosing
With the difference of resin grade, while the requirement to extruder and mold is also different, the performance of obtained polyethylene compound pipe
Naturally different.A kind of good pipeline should not only have good economy, but also should have that interface is reliable and stable, material anti-impact
Hit, cracking resistance, the series of advantages such as ageing-resistant, corrosion-resistant, thus in real life using more and more extensive, so a kind of
Connector for polyethylene compound pipe is also particularly significant.
Summary of the invention
The purpose of the present invention is to provide a kind of polythene composite piping connector and matched polyethylene compound pipe,
Solve the problems, such as that existing pipeline is used only that sealing ring interface is easy to fall off, easy axial displacement.
In order to solve the above technical problems, the invention adopts the following technical scheme:
The inner wall of a kind of polythene composite piping connector, including connecting tube, the connecting tube both ends is respectively arranged with heating resistor
Silk, the heating resistance wire are connect with the electric smelting binding post being located at outside connecting tube, are provided with T between two groups of heating resistance wires
Shape spacing collar, the T shape spacing collar and connecting tube constitute the opposite limiting slot of two opening directions, in the limiting slot of the U-shaped
It is provided with rubber seal.By electric smelting and the dual cooperation of cushion rubber, enhance the firmness connected between pipeline and tightness degree.
Preferably, the T shape spacing collar and connecting tube are integrally formed, increase the firmness of the part of the two.
Preferably, the rubber seal is water swelling rubber ring, better tightness.
Preferably, the limiting slot is gradually reduced from slot bottom to width of rebate, notch has the end of multiple tube
Certain clamping action, and the clamping action has the component for pushing compound pipe end into limiting slot, to a certain extent
Avoid the generation of axial displacement.
Preferably, the rubber seal is provided with extrusion ring, the extrusion ring close to the side of limit channel opening
There are two, it is arranged respectively along the cell wall of limiting slot.
The end of multiple tube is located between two extrusion rings, enhances sealing effect.
Preferably, the extrusion ring, along the direction close to limit channel opening, width is gradually reduced.
Play the role of guidance, reduces resistance of the compound tube wall to extrusion ring when protruding between two extrusion rings to multiple tube
Hinder.
Preferably, being provided in the middle part of slot bottom to ring in the limiting slot.
The ring that supports in the application has extremely important effect, when the tube wall of multiple tube protrudes between two extrusion rings, squeezes
Pressure ring can give rubber seal one power towards limiting slot slot bottom, and sealing ring itself also can generate one under the action of elasticity
A restoring force, when sealing ring and multiple tube between can seal, and will not another rubber ring bear for a long time excessive pressure with
As for deform or elastic force decline, extend the service life of connector.
Preferably, along the direction close to limit channel opening, the width to ring is gradually reduced.
A kind of polyethylene compound pipe matched with the polythene composite piping connector, at least one end are provided with company
Ring is connect, the connection ring is located in the limiting slot of U-shaped and is adapted with the size shape of limiting slot.
Connection ring can be integrally formed with multiple tube, protrude into limiting slot and along the direction far from slot bottom, and thickness is gradually reduced,
It cooperates with limiting slot, limiting slot plays the role of the ring that is clamped and connected, while reducing the axial direction of multiple tube to a certain extent
Displacement.
Preferably, the end face of the connection ring is circumferentially arranged pressurized tank, the pressurized tank is from slot bottom to notch
Width gradually increase.The shape of pressurized tank can cooperate with base ring, so that the sealing between pressurized tank and base ring
Circle is fitted closely with pressurized tank and base ring, and in addition sealing ring is in the elastic force of itself, and outer ring and inner ring have one to connection ring
Close to elastic force so that better tightness between the two.
Compared with prior art, beneficial effects of the present invention are at least one of following:
Limit in connecting tube is limited using T word, inlays two water-swellable cushion rubbers in both sides T mouthfuls of limit.Company in the application
Fitting uses dual-seal, including hot-melting sealed and rubber sealing, fundamentally hydraulic pressure is prevented to penetrate tube wall and pipe fitting
Power and steel wire, which are directly directly contacted with liquid, has an impact water liquid.Rubber ring connection combines electric smelting Joining Technology, by electric heating
It is molten that pipe part welding is integral, overcome that single rubber ring interface is easy to fall off, sedimentation load is low, easy axial displacement, water resistant
The deficiency that thrust is poor, pressure-bearing is low.
Outside combines electric heating melting link also to solve complicated soil environment to rubber ring aging effects.Double water-swellable glue
Circle overcomes common electric heating melting and local empty molten is easily caused to connect.Two kinds of cushion rubber, electric smelting seal approach combine, and play stronger performance
The respective deficiency of complementary and client, cooperates the anti-displacement safe spacing of brand-new design, pipe-line system is even more greatly improved
Interface security.
