AI Technical Summary

Technical Problem

In existing air conditioning systems, valves have low integration with other components, requiring additional piping connections, resulting in large system size and inconvenient layout.

Method used

Design a valve island assembly in which the valve is directly connected to the flow channel inside the valve island through the mounting hole, reducing external piping. The assembly uses a fixing part and a sealing part to ensure a stable connection. The valve body is located inside the mounting hole, achieving compact integration.

Benefits of technology

The integration of valve island components has been improved, piping usage has been reduced, the overall size of the air conditioning system has been reduced, installation in limited spaces has been made easier, reliability and production efficiency have been improved, and costs have been reduced.

Abstract

The utility model discloses a valve island subassembly and air conditioning system, valve island subassembly includes: valve island and valve piece, and the valve island is formed with mounting hole, and the valve island has the intercommunication flow channel, and the mounting hole is linked with at least one intercommunication flow channel, and the valve piece includes valve body, and the valve body has the first valve cavity and the second valve cavity, and is equipped with the valve port portion between the first valve cavity and the second valve cavity, and is equipped with the first valve port of intercommunication first valve cavity and the second valve port of intercommunication second valve cavity on the valve body, and the valve body is located corresponding mounting hole, and the valve body has the fixed portion and the first sealing portion along its axial arrangement, and the fixed portion is fixedly connected with the valve island, and the first sealing portion is sealed with the hole wall of mounting hole and cooperates to separate the first valve port and the second valve port, and at least one of first valve port and second valve port is linked with corresponding intercommunication flow channel. Therefore, the valve piece need not be linked with the valve island through the external connecting pipeline, and the integration of valve island subassembly is improved.
