Connecting assembly, pipeline system and air conditioning system

Abstract

The invention provides a connecting assembly, a pipeline system and an air conditioning system. The connecting assembly is used for connecting a first pipe fitting with a second pipe fitting. The connecting assembly comprises a lining sleeve and a clamping jaw piece, wherein the lining sleeve comprises a first end, and the first pipe fitting is arranged at the first end in a sleeving mode; the clamping jaw piece is movably arranged on the lining sleeve; and the clamping jaw piece and the lining sleeve are used for clamping or loosening the first pipe fitting. The clamping jaw piece is movably arranged, in combination with the lining sleeve, the first pipe fitting is clamped or loosened, the lining sleeve communicates with the first pipe fitting during clamping, and the first pipe fitting can conveniently leave from the lining sleeve during loosening, so that rapid locking or loosening of a pipeline is realized.

Description

technical field [0001] The application belongs to the technical field of air-conditioning systems, and in particular relates to a connection assembly, a pipeline system and an air-conditioning system. Background technique [0002] At present, during the matching or installation process of the air conditioning system, the operation and debugging often use methods such as welding and bell mouth thread transfer to connect the internal and external units, which may involve multiple disassembly and assembly needs. [0003] The welding connection process needs to be based on the installation and commissioning of the air conditioning system. Multiple weldings to varying degrees are required on the inner and outer sides of the machine. In the case of multiple weldings, it is easy to cause overburning at the nozzle position, which will further cause pressure on the connecting material. The strength is reduced, and under the action of pipeline pressure, it may cause system leakage or ...

Problems solved by technology

[0003] The welding connection process needs to be based on the installation and commissioning of the air conditioning system. Multiple weldings to varying degrees are required on the inner and outer sides of the machine. In the case of multiple weldings, it is easy to cause overburning at the nozzle position, which will further cause pressure on the connecting material. Reduced strength, under the action of pipeline pressure, may cause system leakage or even instant explosion, reducing product quality and reliability

[0004] The bell mouth thread transfer is mainly a connection method that uses a threaded joint to cooperate with a flared bell mouth for sealing. The sealing effect of this method depends on the coaxiality between the bell mouth and the threaded joint, and the tightening and sealing effect depends on manual work. The adjustments of debugging and formal installation are uncontrollable. When the tightening is too tight, the clamping force of the threaded joint on the bell mouth is too large, which may cause deformation and damage to the pipeline; when the adjustment is too loose, the clamping force of the threaded joint on the bell mouth If the tightening force is too small, the system may leak under the action of pipeline pressure

At the same time, a large torque is required during the tightening process, which may cause damage to the bell mouth due to unbalanced force. If this happens, it will also cause unreliable connection and leakage of medium. When leakage occurs, it needs to be readjusted or Time-consuming and labor-intensive replacement of connecting pipes

[0005] In the case of multiple disassembly operations involving the air-conditioning connection system, the above two methods cannot meet the fast and reliable docking of product commissioning
