Description

Technical Field

[0001] The utility model relates to the technical field of throttling systems, in particular to a multi-way throttling valve. Background Art

[0002] A multiport flow control valve is a valve device used to control the flow of liquid or gas. It can divert one inlet to multiple outlets, and can control the flow of each outlet by adjusting the opening of each outlet. This valve is usually used in systems that need to distribute fluid to multiple locations or multiple working devices.

[0003] A throttle valve sleeve is arranged in the valve body, and the main valve core is arranged inside the throttle valve sleeve.
