Throttle valve is a valve that changes the cross-sectional area of the passage through the movement of the opening and closing parts (valve disc) to adjust the flow and pressure. The shape and structure of throttle valve is no different from that of stop valve, but the shape of their opening and closing parts is different, mostly conical streamline. The throttle valve has no negative flow feedback function and can not compensate for the speed instability caused by load change. It is generally only used in occasions with little load change or low requirements for speed stability. It is generally used to reduce the medium pressure under the condition of great pressure drop.
