The invention discloses a metal hose capable of assisting in drainage. The metal hose comprises a hose body, connection pipes (3) and flanges (4), and the hose body, the connection pipes (3) and the flanges (4) are connected in sequence; the hose body is provided with an auxiliary drainage mechanism; the auxiliary drainage mechanism comprises a compression gasbag (5), a gas outlet pipe (6), a one-way valve (7), gas guide pipes (8) and a three-way connector (9); the compression gasbag (5) is provided with a gas inlet and a gas outlet, and the gas outlet is connected with one end of the gas outlet pipe (6); the one-way valve (7) is arranged at one end of the gas outlet pipe (6); the other end of the gas outlet pipe (6) is arranged on the hose body in a sealing mode, penetrates through the hose body and stretches into the hose body to be connected with one of connector bodies of the three-way connector (9); and the rest connector bodies of the three-way connector (9) are connected with the gas guide pipes (8). According to the metal hose, through the compression effect of the compression gasbag, gas generated through compression of the compression gasbag can be exhausted in one direction, the gas guiding effect is improved, quick exhaust is achieved through the structure, and the drainage efficiency is improved.
Description
technical field [0001] The invention relates to a metal hose that can assist drainage, and belongs to the technical field of metal hoses. Background technique [0002] Metal hose is a high-quality flexible pipe in modern industrial pipelines. It is mainly composed of bellows and joints. Its inner tube is a thin-walled stainless steel bellows JR rectangular hose with a spiral or annular corrugation, and the outer net sleeve of the bellows is woven by stainless steel wire or steel strip according to certain parameters. The fittings or flanges at both ends of the hose are compatible with the fittings or flanges of the external pipe. [0003] Rectangular metal hose is a new type of drag chain for wire protection. JR-2 rectangular metal hose is a fully enclosed structure. The whole is made of steel. Chrome plated inside and out. It has the characteristics of high sealing, acid and alkali resistance, high temperature resistance, flexible and random bending, complete specific...
