Abstract
Disclosed is an impervious sealed ring for a cable protective pipe which is made of fiber glass reinforced plastics and applied in electric power and communication, comprising a pipe sleeve and an inward convex ring which is integrated with one end of the pipe sleeve and an integral sawtooth ring which has more than two circles of sawtooth. The impervious sealed ring is made of water expand rubber and adopts the micro pore structure. The utility model has high socket efficiency and expands by 3 to 4 times when being contacted with water during the construction process; thereby, the impervious property is ensured.
Description
Technical field
The utility model relates to sealing group (F16J) in International Classification of Patents, also relevant with pipe, pipe joint or pipe fitting group (F16L), particularly the impervious seal ring of frp cable protective pipe.
Technical background
Electric power, communication cable need put cable protection pipe when gap bridge or underground burying underground.Adopted metal pipe, the protection metal pipe quality is big, valency is high, not corrosion-resistant in the past.In recent years; corrosion-resistant easy working glass fibre reinforced plastics protective tube begins extensive use; adopt glass fiber reinforced plastic material and distinctive socket fitting type structure, promptly an end of every section pipe has the flare of the one made, and the internal diameter of enlarging is greater than the external diameter of pipe and form interior edge face.When connecting sealing, seal ring inserts enlarging on a headgear of another section pipe, till above-mentioned port.Existing seal ring adopts the General Purpose Rubber material, and its structure is that an end of rubber sleeve is connected with inside bulge loop, and the outer wall of rubber sleeve has the spaced saw-tooth ring of some circles of the one made, and the sawtooth hypotenuse is positioned at bulge loop one side.The internal diameter of rubber sleeve equals the external diameter of glass fibre reinforced plastics protective tube, and the aperture of bulge loop equals the internal diameter of protective tube.Put the enlarging of inserting protective tube behind the seal ring, the inwall of sawtooth and enlarging pushes against, and its pawl produces sealing and only pulls out effect.This type of seal ring is in the protective tube construction, and work efficiency is higher, and is also corrosion-resistant, but water permeability resistance can be relatively poor.
The machine patent information retrieval does not detect the water seepage resistant seal ring of frp cable protective pipe as calculated.
The model utility content
The purpose of this utility model is that it has the water permeability resistance energy for frp cable protective pipe provides supporting seal ring, possesses socket joint simultaneously and is easy to advantage.
It is as follows to disclose new technological scheme:
The impervious seal ring of frp cable protective pipe comprises pipe box and the inside bulge loop that fuses with the one end; outer tube wall has the above saw-tooth ring of two circles of the one made; the hypotenuse of sawtooth is positioned at bulge loop one side; the sawtooth height lowers gradually to the bulge loop aspect; it is characterized in that said seal ring; the mixed polyamine ester that hydrophilic group is arranged is microcellular structure in rubber.
The sample of making according to such scheme is through on probation, except that having the high advantage of socket joint work efficiency, can expand 3-4 doubly after mainly being to meet water, thereby guarantee the water permeability resistance energy of pipe network.

Embodiment
As can be seen from Figure 1; the impervious seal ring of frp cable protective pipe comprises pipe box 2 and the inside bulge loop 3 that fuses with the one end; the above saw-tooth ring 1 of two circles that the one made is arranged on pipe box 2 outer walls; the hypotenuse of sawtooth is positioned at bulge loop 3 one sides; the sawtooth height lowers gradually to bulge loop 3 directions; it is characterized in that said impervious seal ring adopts the rubber material of water-swellable, promptly mixing in rubber has hydrophilic group [CH
2-CH
2-O-] polyamine ester.Be microcellular structure.Group after meeting water with water molecules, volume increases 3-4 doubly, thereby makes the expansive force increase between seal ring 5 and the protective tube 4, reaches to prevent the purpose that seeps water.Said impervious seal ring 5 is enclosed within an end of protective tube 4 in assembling, insert in the enlarging 6 of another protective tube 4, and bulge loop 3 joins with the interior edge face of enlarging 6, and saw-tooth ring 1 offsets with the inwall of enlarging 6.
Claims (1)
