Socket press fit armor composite pipe

Abstract

The invention discloses a bell-spigot pressing-type armor composite pipe, which comprises a connecting pipe used for guiding gas; a metal spiral pipe and a heat shrinkable sleeve sheathe the connecting pipe in sequence from inside to outside; two ends of the connecting pipe are respectively provided with a bell-spigot pressing-type pipe fitting; each bell-spigot pressing-type pipe fitting comprises a main pipe body and a pressing pipe; two ends of the connecting pipe and two ends of the metal spiral pipe are located between the main pipe bodies and the pressing pipes of the bell-spigot pressing-type pipe fittings at the corresponding ends; the heat shrinkable sleeve coats the pressing pipes; one end, far away from the connecting pipe, of each bell-spigot pressing-type pipe fitting is provided with a connector. According to the bell-spigot pressing-type armor composite pipe disclosed by the invention, the metal spiral pipe is capable of preventing a gas pipe from being gnawed to grind teeth by mice, and preventing the connecting pipe from damaged or scalded by high-temperature radiation; the heat shrinkable sleeve is thermally shrunk to coat the metal spiral pipe so as to protect the metal spiral pipe and the connecting pipe; meanwhile, the bell-spigot pressing-type armor composite pipe has an auxiliary leakage control function; the gas can be effectively prevented from leaking from the end part of the connecting pipe by the double-layer seal structure of each bell-spigot pressing-type pipe fitting.

Description

technical field [0001] The invention relates to a household gas hose for connecting the gas stove inlet and the gas pipe outlet, in particular to a socket and press-fit armor composite pipe. Background technique [0002] At present, the gas hoses used in households are mostly made of rubber or thermoplastic materials, and are connected with the gas stove inlet and the gas pipe outlet by clamps. On the one hand, the clamps are manually tightened by the operator, and the tightness is different, and they are used for a long time. After aging, the connection is easy to fall off and leak air. On the other hand, the material of the gas hose is soft, and the food residue adhered to it is easy to break and leak air after being gnawed by the molars of mice. An open flame is prone to explosion. In addition, the gas hose near the cooker is easily scalded by high-temperature oil, damaged by high-temperature radiation from open flames, and the aging speed is fast. The joints are heated ...

[0002] At present, the gas hoses used in households are mostly made of rubber or thermoplastic materials, and are connected with the gas stove inlet and the gas pipe outlet by clamps. On the one hand, the clamps are manually tightened by the operator, and the tightness is different, and they are used for a long time. After aging, the connection is easy to fall off and leak air. On the other hand, the material of the gas hose is soft, and the food residue adhered to it is easy to break and leak air after being gnawed by the molars of mice. Open flames are prone to explosion

In addition, the gas hose near the cooker is easily scalded by high-temperature oil, damaged by high-temperature radiation from open flames, and the aging speed is fast. The joints are heated for a long time and the cooker moves easily to loosen and slip. The service life of this kind of gas hose is very short. 1 and a half to 2 years, the aging speed is fast, the gas hose must be far from the same life requirement as the stove, and the gas leakage prevention effect is also very poor, posing a great safety hazard

Even if the current pipe is wrapped with metal in plastic to strengthen its strength, the metal is a mesh structure, and the plastic is directly exposed. Once the outer plastic cup is damaged, the metal mesh layer in the middle of the plastic cannot form a protective layer against the inner plastic. More powerful protection, the metal mesh still cannot avoid the above-mentioned problems such as high temperature, rat bite, oil splash, etc.
