Joint connecting device of corrugated stainless steel hose for connection of gas appliance

Abstract

The invention discloses a joint connecting device of a corrugated stainless steel hose for connection of a gas appliance. The joint connecting device comprises the hose. The hose comprises a corrugated section and a straight pipe section located at the end of the corrugated section and connected with the corrugated section into a whole. The outer surface of the corrugated section is coated with a plastic jacket. The outer surface of the straight pipe section is coated with a thermal shrinkage insulation sleeve sleeved with a fastening ring. A port of the fastening ring is provided with a conic face. Outer ports of the straight pipe section and the thermal shrinkage insulation sleeve are provided with a horn opening matched with the conic face. A nut is screwed to the fastening ring and internally provided with a rubber sleeve, wherein the two side faces of the rubber sleeve are outer conic faces, one outer conic face on one side is matched with an inner conic face in the nut, and the one outer conic face on the other side is matched with the horn opening. The joint connecting device has the following beneficial effects that due to the fact that the straight pipe section is sleeved with the thermal shrinkage insulation sleeve and a metal sleeve, even though the straight pipe section is broken down through an electric arc, the thermal shrinkage insulation sleeve cannot be broken down, danger generated by electric breakdown is eliminated fundamentally, and meanwhile the strength of a joint cannot be affected.

Description

technical field [0001] The invention relates to a connection interface of a novel pipe material of a material processing machine, in particular to a socket connection device of a stainless steel corrugated hose used for connecting a gas appliance. Background technique [0002] Stainless steel corrugated hoses are suitable for fixed installation of gas cookers and other gas appliances. Because stainless steel corrugated hoses have high pipe strength, large flow, corrosion resistance, long service life, not easy to aging, and anti-rat bites, they have been widely used in recent years. The domestic gas industry has been vigorously promoted and used. [0003] From the point of view of the connection interface, the vast majority of gas cookers in China still use the traditional socket connection method. This kind of connection method, especially when the hose joint is not standard and the overall size is too small, the joint is easy to leak or even fall off; Connect the wires t...
