Description

Technical Field

[0002] Valves are control components in fluid delivery systems, used to open and close pipelines, control flow direction, and adjust and control parameters of the conveyed medium. According to their functions, valves can be divided into shut-off valves, check valves, regulating valves, etc. When the valve conveys the medium, its flow rate needs to be adjusted according to different requirements, so a flow adjustment mechanism is required.

[0003] According to a butterfly valve flow adjustment mechanism disclosed on the patent website (authorization announcement number: CN 213451748 U) described in "The utility model discloses a butterfly valve flow adjustment mechanism, including a flange butterfly valve and a flow limiting valve. A first electric-controlled valve is installed on the top surface of the flange butterfly valve, and the bottom end of the first electric-controlled valve is fixedly connected to the top surface of the flange butterfly valve by screws; a second electric-controlled valve is installed on the top surface of the flow limiting valve, and the bottom end of the second electric-controlled valve is fixedly connected to the top surface of the flow limiting valve by screws; an electric-controlled device is arranged on the right side of the first electric-controlled valve, and the left side of the bottom end of the electric-controlled device is fixedly connected to the right side of the first electric-controlled valve, and the right side of the top end is fixedly connected to the left end of the second electric-controlled valve; the butterfly valve flow adjustment mechanism controls the flow by the electric-controlled device and the electric-controlled valve, which is efficient and space-saving. When the butterfly valve is opened to pass the flow, the electric control box will control the worm according to the command of the remote terminal, and drive the flow adjustment circular valve to rise and fall to the gradually widening hole. The flow of the butterfly valve is controlled by controlling the blocking area of ​​the gradually widening hole.
