Description

Technical Field

[0001] The invention relates to the technical field of throttle valves, in particular to a precisely controlled low-torque orifice throttle valve. Background Art

[0002] The working principle of the throttle valve is to control the fluid flow by changing the throttling section or the throttling length. When the fluid flows through the throttle valve, the flow section suddenly shrinks, resulting in an increase in flow velocity and a drop in pressure. The magnitude of the pressure drop depends on the proportion of the contraction of the flow section. The throttle valve has no flow negative feedback function, so it cannot compensate for the speed instability caused by load changes. It is usually used in situations where the load changes are not large or the speed stability requirements are not high. When the existing low-torque orifice throttle valve is working, the fluid enters the valve body, affecting the sealing of the entire low-torque orifice throttle valve, and the existing low-torque orifice throttle valve controls the throttle valve flow manually, with a low accuracy. At the same time, when the existing low-torque orifice throttle valve is supported, the staff needs to support it with wall bricks, increasing the overall cost. Summary of the invention
