Novel vacuum connecting pipe

Abstract

The invention discloses a novel vacuum connecting pipe and relates to the technical field of connecting devices. The novel vacuum connecting pipe comprises a pipe body, a vacuum pump, a vacuum box, a vacuum meter and a valve. A protecting layer is arranged on the outer side of the pipe body, rapid connectors are fixed at two ends of the pipe body, the connecting pipe is connected to the position in the middle of one side of the pipe body, the vacuum meter is arranged on the connecting pipe which is connected with a buffer box, the buffer box is connected with the vacuum pump, and a hollow pipe with the valve is arranged on the other side of the pipe body. The protecting layer is arranged on the pipe body, so that the pipe body can be effectively prevented from being damaged; meanwhile, the connecting pipe is serially connected with the buffer box and the vacuum pump, a buffering function of the buffer box is achieved, vacuum data can be clearly reflected through the pressure meter, and the valve can be opened when vacuum is not needed; the novel vacuum connecting pipe is reasonable in design, wide in application range and worthy of promotion and use.

Description

technical field [0001] The invention relates to the technical field of connection devices, in particular to a novel vacuum connection tube. Background technique [0002] The connecting pipe is a connecting fitting in the pipeline installation, which is used for reducing the diameter, leading out the branch, changing the direction of the pipeline, sealing the end of the pipeline, etc. The connection of the pipe fittings mainly includes threaded connection, socket connection and electrothermal fusion welding. The pipes, fittings and ancillary equipment should be checked according to the design requirements, and the appearance inspection should be carried out at the construction site, and they can only be used if they meet the requirements. The main inspection items include pressure resistance grade, outer surface quality, fit quality, material consistency, etc. Pipes of different materials are connected together with special connecting pipe fittings, which generally transi...

Problems solved by technology

The main inspection items include pressure resistance grade, outer surface quality, fit quality, material consistency, etc. Pipes of different materials are connected together with special connecting pipe fittings, which generally transition to copper first, and then through copper Transition to another material, such as the Chinese application number CN 102748550 A discloses a connecting pipe, which provides a new type of connecting pipe that is easy to twist and lock, is not easy to corrode and wear, and is not easy to fall off. The connecting pipe has no vacuum effect, and at the same time, there is no protective layer, so the use is relatively limited
