Abstract
A wedge-shaped silicon sulfide rubber ring can be applied to a heat-supply pipe network operation environment and a thermal machine top pipe connector structure, has an extrusion deformation guide function and can effectively prevent leakage of a connector for a long time, thereby improving the safe operation quality of a heat-supply pipe network. The wedge-shaped silicon sulfide rubber ring is characterized in that the cross section of the rubber ring is a wedge-shaped section, the wedge-shaped section comprises a wedge-shaped bottom, a wedge-shaped top opposite to the wedge-shaped bottom, a tension side on the right side and a compression side on the left side, wherein the wedge-shaped bottom has a sawtooth-shaped bottom edge, the compression side is a concaved arc-shaped edge, and the tension side is a linear inclined edge.
Description
Technical field
The present invention relates to waterproof or the water seepage-proof tech of thermal machine push pipe interface, a kind of wedge shape vulcanizing silicone rubber cushion rubber particularly, be applicable to heat distribution pipe network running environment and thermal machine push pipe interface structure, there is extrusion-deformation guide function, can effectively prevent interface seepage, thereby improve the safe operation quality of heat distribution pipe network.
Background technique
In thermal machine push pipe interface, have waterproof or anti-leakage structure, use therein seal with elastometic washer is regarded as merely static sealing conventionally.But the inventor notices, the formation of thermal machine push pipe interface is actual is a dynamic process, and the formation of interface need to utilize push pipe machinery to make end-to-end between push pipe and push pipe.So whether rubber ring compressed end-state in whole using process is suitable, it is the determinant factor of check rubber ring reasonable structure.Therefore, the inventor thinks, be necessary to make the structure of rubber ring to there is extrusion-deformation guide function, to adapt to the pushing tow process of end-to-end between push pipe and push pipe, make the final confined state of rubber ring can guarantee that sealing effect can reduce amount of deformation again, thereby be more conducive to effect of the thermo-oxidative ageing, mechanical stress and the water that occur in permanently effective reply using process etc.
Summary of the invention
The present invention is directed to the defect or the deficiency that in prior art, exist, a kind of wedge shape vulcanizing silicone rubber cushion rubber is provided, can be applicable to heat distribution pipe network running environment and thermal machine push pipe interface structure, there is extrusion-deformation guide function, can effectively prevent interface seepage, thereby improve the safe operation quality of heat distribution pipe network.
Technological scheme of the present invention is as follows:
Wedge shape vulcanizing silicone rubber cushion rubber, the cross section of described cushion rubber is wedge shape section, it is characterized in that, described wedge shape section comprises wedge shape bottom and the wedge-shaped top relative with described wedge shape bottom, and the tensile side that is positioned at right side is surveyed with the compression that is positioned at left side, described wedge shape bottom has zigzag fashion base, and described compression is surveyed as depression arc-shaped side, and described tensile side is straight line hypotenuse.
Described wedge-shaped top is arch dome.
The top margin of described wedge-shaped top connects respectively described depression arc-shaped side and described straight line hypotenuse by transition arc.
Described depression arc-shaped side is all longer than on described straight line hypotenuse and described zigzag fashion base.
Described wedge shape bottom comprises that groove embeds left side and groove embeds right side.
It is the left side straight line perpendicular to the base of described wedge shape bottom that described groove embeds left side.
It is the right side straight line perpendicular to the base of described wedge shape bottom that described groove embeds right side.
Described left side straight line is connected by transition arc with the base of described wedge shape bottom.
Described right side straight line is connected by transition arc with the base of described wedge shape bottom.
Zigzag fashion base is combined with vulcanization type silicone rubber adhesive layer.
The technology of the present invention effect is as follows: wedge shape vulcanizing silicone rubber cushion rubber of the present invention is by arranging the depression compressed side of arc-shaped side and the tensile side of straight line hypotenuse, when wedge-shaped top is squeezed, for example, between push pipe and push pipe in the pushing tow process of end-to-end, top can be to compressed side deflection deformation, that is to say that this structural feature has formed the extrusion-deformation guide function of wedge shape cushion rubber, this extrusion-deformation guide function makes the final confined state of rubber ring can guarantee that sealing effect can reduce amount of deformation again, thereby be more conducive to the thermo-oxidative ageing occurring in permanently effective reply using process, the effect of mechanical stress and water etc.
Zigzag fashion base is conducive to being adhesively fixed of wedge shape bottom.In use, wedge shape vulcanizing silicone rubber cushion rubber is bonded in groove, and tackiness agent, through preferably, adopts vulcanization type silicone rubber adhesive.In the assembling test of waterproof ability, vulcanization type silicone rubber adhesive can be realized and exceed in other words the excellent effect of anticipation significantly aspect leakage proof.In tunnel pipelines engineering, widely used tackiness agent is Choropene phenol aldehyde adhesive, and two outer epoxy resin, commercially available instant drying adhesive water etc. are the conventional tackiness agents of selecting.Through comparative trial, vulcanization type silicone rubber adhesive is convenient operation both, and effect is good again.The temperature of the common working environment of thermal pipe is higher, and after research and testing, good high temperature resistant, the ageing-resistant performance of silicone rubber can be applicable to the working environment of thermal pipe for a long time.
The present invention meets micro-tunneling technology and is applied in the feature in heat enginnering construction.In a word, wedge shape vulcanizing silicone rubber cushion rubber of the present invention can be applied in heat distribution pipe network running environment, and meets the requirement of thermal machine push pipe interface structure, also has extrusion-deformation guide function, can effectively prevent interface seepage, thereby improve the safe operation quality of heat distribution pipe network.
