Out-wall joint and assembly method thereof for embedded metal hose

Abstract

The invention relates to an out-wall joint and an assembly method thereof for an embedded metal hose. An external joint is arranged at one end of a bent pipe body; a joint insert with an internal thread is arranged in the external joint; an inner ring stopper is arranged at the inner end of the internal thread of the joint insert; and a hose inlet end is arranged at the other end of the bent pipe body and is provided with a protecting cover through a clamping structure. The assembly method comprises the following steps of: opening the protecting cover; feeding the metal hose; tapping out a flange plain washer to make the flange plain washer butted against the inner ring stopper; buckling the protecting cover; and assembling the out-wall joint inside a wall body. According to the out-wall joint and the assembly method thereof, the metal hose can be directly connected in a bending manner, the out-wall joint has a simple structure, a small volume, high safety and convenience for assembly by embedding in a wall; the assembly is more convenient and faster, stable and reliable, ensures that the whole pipe body is embedded in the wall, improves the safety of using stainless steel corrugated hoses, and prolongs the service life of products; and the out-wall joint has the advantages of artistic appearance, reasonable design and low production cost, is integrated with indoor decoration and is worthy of being popularized and used.

Description

technical field [0001] The present invention relates to a joint and an installation method for a hose, in particular to a buried wall joint for a buried stainless steel corrugated hose, that is, a wall joint for a buried metal hose and its installation method . Background technique [0002] The buried metal hose is a hose specially used for the transmission and connection of gas sources such as gas, petroleum liquefied gas, natural gas, and biogas, which can be buried and laid on the indoor wall and ground. Because of its good flexibility, fatigue resistance, high pressure bearing, good temperature resistance, corrosion resistance, strong sealing and many other characteristics, it has a much longer life than other hoses (rubber hoses, plastic hoses). Therefore, it can be widely used in aviation, aerospace, petroleum, chemical industry, steel, electric power, papermaking, construction, rubber, textile printing and dyeing, medicine, food, transportation and other industries. ...

AI Technical Summary

Problems solved by technology

[0004] 1. The construction is difficult, because the volume of the wall box is relatively large, and the wall box must be buried in the wall as a whole, so the width and depth of the slot must be increased, which increases the difficulty of construction;

[0005] 2. The installation is cumbersome and the efficiency is low. An elbow with a base needs to be installed inside the wall box, which increases the difficulty of installation;

[0006] 3. The cost is high, the material cost of the wall box is 5 to 8 times that of the ordinary wall joint;

[0007] 4. There are potential safety hazards; because the corrugated hose needs to be connected through a turning joint in the wall box, and then another corrugated hose is connected to the equipment to be connected, and in this installation method, a turning must be used The turning joint is used to achieve the purpose of turning out of the wall. Therefore, installing one more joint will bring more safety hazards
