Abstract

The utility model relates to an anti-drop anti-leakage connector for PE plastic pipe used to avoid the break of the PE pipe under the frequent impact of the high water pressure or the pressure change when the PE plastic pipe being connected . The anti-drop anti-leakage connector for PE plastic pipe adopts the double anti-drop device. An anti-drop ring is drove into the end of the PE pipe and inserted in the PE pipe, and thus, hardness of the PE pipe is enhanced, the roundness of the PE pipe is improved, and the caliber of the PE pipe is enlarged in a head shape of the tortoise; the anti-drop anti-leakage connector for PE plastic pipe has the function of self-anti-drop because the caliber of the pipe with the head shape of the tortoise is longer than the inner diameter of a pipe clamp, the PE plastic pipe is uneasy to drop, and one anti-drop device is formed; the pipe clamp is made of rigid cellular plastic, the inner diameter is provided with the convex-edge teeth which can bite on the PE pipe, and the other anti-drop device is formed. The port of the pipe fitting body and the contact surface of the rubber sealing ring are sealed by the conical surface, which avoids the leakage by enlarging the contact area and the intensity of the seal.

Description

PE plastic tube anticreep leakproof link

Affiliated technical field

The utility model is a kind of in the connection of PE plastic tube, prevents under the frequent impact of high hydraulic pressure or variation in pressure and the anticreep leakproof link that is disconnected.

Technical background

In the connection of current PE plastic tube, the link that is adopted, unreasonable because of anti-drop device and sealing configuration, so be unable to undergo high hydraulic pressure or the frequent impact of variation in pressure, can take off in the use and take off again or seepage, very impracticable.

Summary of the invention

For overcoming the deficiency of existing PE pipe connecting member of plastics material, the utility model provide a kind of can be under the frequent impact of high hydraulic pressure or variation in pressure and do not take off the link that does not leak.

The scheme that the utility model adopted is: make two nuts, two duroplasts pipe clamps, two plain cushions, two rubber seal, two anti-decylizations, a pipe fitting body.Nut is funnel shape, and front end bucket body inwall is an internal thread, the inside and outside taper that is in rear end, in bucket body and cone connecting part, in establish a fin, be provided with equidistant card nose in the bucket body outside; Pipe clamp, front end has a convex hole, opens a contraction mouth on the ring, and its external diameter is slightly less than the nut internal diameter, internal diameter is consistent with the plastic tube external diameter, there is the cone sheet rear end, and inwall is provided with the fin tooth, and its internal diameter conforms to the plastic tube external diameter, ectosome is the conical surface, the rear end cone inner conical surface of its conical surface and nut can coincide, and the contraction mouth on convex hole under the compressing of nut cone shrinks, and the fin tooth can be engaged on the plastic tube; Rubber seal, its internal diameter is consistent with the plastic tube external diameter, and external diameter is slightly less than the nut internal diameter, and the front end outside is a cone-shaped, can increase the surface of contact of sealing, and the rear end is a disc shape; Anti-decylization, the front end ectosome is a cone-shaped, and the rear end is a disc shape, in the outer connecting part of cone-shaped and disc shape an overhead kick ring is arranged, and its external diameter is greater than the internal diameter of plastic tube; The pipe fitting body, the ectosome middle part is provided with equidistant draw-in groove, and two ends, the left and right sides are screw thread, and internal diameter is the external diameter sum that the double thickness of plastic tube adds anticreep overhead kick ring, and the interior edge of two-port is the conical surface, the conical surface on its conical surface and the rubber seal coincide.On connected two plastic tubes, overlap upper cap nut, pipe clamp, plain cushion, rubber seal in the opposite direction successively; Respectively squeeze at two ports of plastic tube and to inlay an anti-decylization, its hardness is strengthened, circularity is better, and caliber strengthens, and is the glans penis shape, and inserts in the pipe fitting body, respectively nut is combined with pipe fitting body screw thread rotation.

Like this, because anti-decylization makes the termination portion of plastic tube be the glans penis shape, overhead kick ring on the anti-decylization can be prevented deviating from certainly, its outer tube diameter is greater than the pipe clamp internal diameter, the external diameter of pipe clamp convex hole is greater than the fin internal diameter on the nut, under the rotatablely moving of nut and pipe fitting body screw thread, force the conical surface and the pipe fitting body port inner conical surface tight connecting of rubber seal, the fin tooth in the cone sheet of the pipe clamp of nut back end cone compressing simultaneously rear end is engaged on the plastic tube.Therefore, connected plastic tube is difficult to throw off and seepage under the frequent impact of high hydraulic pressure or variation in pressure.
