The invention discloses a heat-insulating
gasket, which comprises a threaded hole,
absorbent cotton, a fitting port, a cock, a
moisture-proof
air barrier, a bracket, an end cover, a telescopic spring, a
thermal insulation layer, and a bolt. Penetrating through the center of the bracket, the telescopic spring is composed of a conductive angle, a spring, a telescopic rod, a pillar, a steel cap, and a damping pad. The invention is a
thermal insulation gasket, and the spring and the damping pad are fixed inside the bracket through the conductive angle. , when the operator installs the heat insulation
gasket in the connection gap of the
mechanical equipment, the damping pad will drive the telescopic rod to press down the spring, and the support will be embedded in the steel cap to prevent the telescopic spring from twisting and bending; it will be replaced next time When the spring is not under pressure, it will automatically bounce outwards to keep the telescopic spring
horizontal and vertical, so that it can be used repeatedly and solve the problem of frequent replacement of heat insulation gaskets.
