AI Technical Summary
Technical Problem
In the existing multi-connection air conditioning system, the cost increase is caused by the installation of a shut-off valve and a multiple expansion valve.
Method used
A shut-off valve is designed. The shut-off valve is designed by opening multiple throttling holes with different areas on the fixing sheet and opening a flow opening on the rotating sheet. Different throttling effects are achieved through the relative rotation of the rotating sheet and the fixing sheet, integrating the on-off function of the traditional shut-off valve and the throttling function of the electronic expansion valve.
Benefits of technology
Reduces the number of parts, reduces costs, and improves the safety of the air conditioning system and the convenience of maintenance.

Abstract
The utility model relates to the technical field of valves, in particular to a stop valve and a multi-split air conditioning system. The stop valve comprises a valve body assembly, a valve element, a fixed piece and a rotating piece. The valve body assembly is provided with a valve cavity, and at least part of the valve element is installed in the valve cavity and rotationally matched with the valve body assembly. The fixing piece is arranged in the valve cavity and fixedly connected with the valve body assembly in a clamped mode, a plurality of throttling holes with different flow areas are formed in the fixing piece, and a sealing part is further arranged on the fixing piece. The rotating piece is matched with the fixed piece in an abutting mode, the rotating piece is connected to the valve element and can be driven by the valve element to rotate relative to the fixed piece, a circulation opening is formed in the rotating piece, and along with rotation of the rotating piece, the circulation opening can be communicated with the corresponding throttling hole, or the circulation opening is matched with the sealing part so that communication between the circulation opening and the throttling hole can be cut off. According to the stop valve and the multi-split air conditioning system, the problem that the cost is increased due to the fact that a stop valve and a plurality of expansion valves are arranged in an existing multi-split air conditioning system is solved.
