Structural principle of throttle valve（1）

A throttle valve is composed of a valve body, valve core, spring, sealing ring, etc. Among them, the valve body is the outermost layer of the throttle valve, and there is a throttle port inside it. The valve core is the core component of a throttle valve, which controls the flow rate by moving it up and down. The spring is used to control the movement of the valve core and maintain it in a certain position. The sealing ring is used to prevent liquid or gas leakage from the valve core.

When the valve stem pushes the valve core, the shape of the valve core will change, thereby changing the flow rate of the fluid and achieving the purpose of throttling. When the valve stem pushes the valve core, the shape of the valve core will change, thereby changing the flow rate of the fluid and achieving the purpose of throttling. When the valve stem pushes the valve core, the shape of the valve core will change, thereby changing the flow rate of the fluid and achieving the purpose of throttling.
