Hot-melt elbow connecting joint

Abstract

The invention discloses a hot-melt elbow connecting joint. The hot-melt elbow connecting joint comprises a hot-melt connecting pipe, inner connecting structures and an outer connecting structure. Metal joints are symmetrically arranged at the left end and the right end of the hot-melt connecting pipe, a sealing ring plate is arranged at the center in the hot-melt connecting pipe, a hot-melt pipe is connected to the right side in the hot-melt connecting pipe in an inserted mode, the left end of the hot-melt pipe is attached to the right side face of the sealing ring plate, inclined cone clamping grooves are symmetrically formed in the outer arc surface of the hot-melt pipe, inclined surfaces of the inclined cone clamping grooves are arranged in an inclined mode from outside to inside, a connecting plate is arranged on the outer arc surface of the hot-melt pipe, and the connecting plate is located on the right side of the inclined cone clamping grooves. The inner connecting structures are symmetrically arranged in the metal joints. According to the hot-melt elbow connecting joint, dual connection and fixation can be conducted on the hot-melt pipe from the inside and the outside at the same time, the comprehensiveness of connection is guaranteed, unstable connection caused by misoperation can be prevented, the contact area of the hot-melt connecting pipe and the hot-melt pipe canbe increased, and the tightness of hot-melt connection is further improved.

Description

technical field [0001] The invention relates to the technical field of hot-melt connection, in particular to a hot-melt elbow connection joint. Background technique [0002] Hot-melt connection refers to the connection between non-metal and non-metal. It is a connection method after heating to the (liquid) melting point. It is widely used in PP-R pipes, PB pipes, PE-RT pipes, metal composite pipes, and curved pipes. Elastic vector aluminum alloy lined plastic composite pipe system and other new pipes are connected with pipe fittings. In steel structure engineering, two metal steel bars are connected by hot melting through electric heating equipment. The connection point after metal hot melting connection must be in the Only by cooling at room temperature can the tensile stress of the original metal material be achieved.

[0002] Hot-melt connection refers to the connection between non-metal and non-metal. It is a connection method after heating to the (liquid) melting point. It is widely used in PP-R pipes, PB pipes, PE-RT pipes, metal composite pipes, and curved pipes. Elastic vector aluminum alloy lined plastic composite pipe system and other new pipes are connected with pipe fittings. In steel structure engineering, two metal steel bars are connected by hot melting through electric heating equipment. The connection point after metal hot melting connection must be in the Only by cooling at room temperature can the tensile stress of the original metal material be achieved. The hot melt connection must not be quenched, so as to prevent the joints from carbonizing and becoming brittle, and losing the tensile stress parameters of the original metal material. The hot melt connection mainly includes: hot melt socket connection and Hot-melt butt welding connection, hot-melt connection has the advantages of simple connection, long service life, and not easy to corrode. The existing hot-melt joints often cannot guarantee the comprehensiveness of the connection, and the connection quality is relatively average. Therefore, in order to solve the above problems, We have designed a hot-melt elbow joint
