Abstract

The invention belongs to the airborne equipment technology, and the invention relates to a rubber heating pad used in the water and waste water system of an aircraft, in particular to a rubber heating pad with an automatic temperature control function, that is, an automatic temperature control rubber heating pad. The automatic temperature control rubber heating pad includes rubber seals, electric heating alloy wires, and a thermostat. The electric heating alloy wires and temperature controllers are placed in rubber. Completely isolated, the shape of the electrothermal alloy wire is straight or wound into a spiral state, and the heating circuit is led out by two high temperature resistant wires. The invention is installed in the water filling joint, sewage discharge joint and cleaning joint, which can prevent the water filling joint, sewage discharge joint and cleaning joint from freezing when the aircraft is flying, and the service life can reach 30 years or 30,000 flight hours.

Description

An automatic temperature control rubber heating pad technical field The invention belongs to the airborne equipment technology, and relates to a rubber heating pad used in the water and waste water systems of an aircraft, in particular to a rubber heating pad with automatic temperature control function, that is, an automatic temperature control rubber heating pad. Background technique When the aircraft is flying in the atmosphere, the interface of the water and wastewater system of the aircraft needs to be heated by a rubber heating element to electrically heat the interface of the water and wastewater system, so that the above-mentioned product pipeline interface does not freeze or has the ability to melt ice. If the rubber heating element is not used, the pipeline interface of the water and waste water system of the aircraft will freeze, and in severe cases, the pipeline will be blocked by ice, which will affect the operation of the water and waste water system of the air...
