Manufacturing method of nanometer inner film tubular electrothermal film electrothermal tube

Abstract

Disclosed is a manufacturing method of an inner film nanometer electrothermal film electrothermal tube. The structure of the electrothermal tube is as follows: a quartz glass tube which is coated with a film and has a hemispherical sealing bottom at one end and an opening in the other end, a micro crystal tube or a ceramic tube are adopted as the basic components; a power connecting metal ring, a lead and a lead insulating sleeve are arranged in the tube; a silica gel sealing sleeve, an end cap and a flange are arranged in the tube opening position; the power connecting lead is connected to an external power connecting electric wire through a via hole of the end cap; the lead which passes through the end cap, and the via hole in the end cap are encapsulated and sealed by adopting high-temperature sealing adhesive; a threaded tooth hole or a vacuumizing apparatus connector end cap is arranged on the end cap for discharging the air in the electrothermal tube by a heat discharging method or a vacuumizing method completely; the interior of the electrothermal tube is in a negative voltage or vacuum state, so that connection between the inside and the outside of the tube is isolated; and therefore, heated water and other liquid does not overflow even if the inner film tubular nanometer electrothermal tube is broken.

Description

technical field [0001] The invention relates to an electric heating tube, in particular to a manufacturing method of a nano inner film tubular electric heating film electric heating tube. Background technique [0002] In the inner membrane nanotube electric heating film electric heating tube products, the electric heating tube is composed of the internal lead metal ring, the lead wire and the lead wire insulating sleeve, and the nozzle part is composed of a silicone sealing sleeve or a silicone sealing sleeve plus a plug and a flange. The design of the lead wiring method and the silicone sealing method of the flange head part is as follows: the lead wire is drawn out from the hole at the end of the silicone sealing sleeve and then connected to the connecting terminal or screw column, and the silicone end is separately connected to the inside of the tube and the tube. The vent hole outside, or the end of the plug has a vent hole connecting the inside and outside of the pipe, ...
