The utility model content
The purpose of this utility model produces thus, proposes a kind of high-temp. resistant water-cooled cable, solves existing water-cooled cable and can not use under hot environment, the problem of copper bar connection inconvenience.Water-cooled cable can be used under high temperature (more than 300 ℃) environment, has expanded the scope of application of water-cooled cable, and easy for installation, effectively reduce use cost, improved the useful life of water-cooled cable.
The utility model is realized the technical scheme that above-mentioned purpose is taked: a kind of high-temp. resistant water-cooled cable comprises left electrode, water inlet tap, the software wire, the oversheath insulated tube, faucet, right electrode, the two ends of software wire respectively with left electrode be connected electrode and be connected, the oversheath insulated tube is set with on it, and water inlet tap is arranged on left electrode, and faucet is arranged on right electrode, described oversheath insulated tube is bellows, two ends are connected with flange, also are connected with flange on the right electrode of left electrode, and the oversheath insulated tube is fixedly connected with by flange with the right electrode of left electrode.
Be connected with sealing ring between oversheath insulated tube described in the utility model and left electrode and right electrode.
The outer insulation of oversheath insulated tube described in the utility model is bar shaped silica gel cloth winding arrangement, or is the glass tape winding arrangement, or is that the surface is ceramic layer structure.
The utility model adopts the flange and the structure that is connected with fastened by screw after flange on left electrode, right electrode adds sealing ring on the oversheath insulated tube, because the bellows material is the 1Cr18Ni9Ti of rigidity, to be fixed to it on left and right electrode, if fix with clip, although can be fastening, faying face be certain to leak (because both being the rigid objects matched in clearance).Guarantee water-tightly herein, only have with flange and encrypt the seal syndeton.
Advantage of the present utility model: High temperature resistant, can use in environment more than 300 ℃;
