Abstract

The invention discloses a convergence and divergence nozzle adjusting valve. The convergence and divergence nozzle adjusting valve comprises a valve body, a valve seat, a plurality of flow guide plates, rotating pins, air bags and an air nozzle, wherein the valve seat is fixedly connected to the valve body through a screw; a plurality of grooves are formed in the circumferential direction of the valve seat; the large end of each flow guide plate is plugged into the corresponding groove of the valve seat, and each flow guide plate is rotationally hinged to the valve seat through the corresponding rotating pin; and each air bag is arranged in the space between the valve body and the corresponding flow guide plate, and the air bags are externally connected with a high-pressure air source through the air nozzle. According to the convergence and divergence nozzle adjusting valve, the linear streamline design is adopted instead of the fluid turning design; and fluid turning is avoided in the adjusting process of the valve, flow resistance is reduced, and the pressure loss is reduced. Meanwhile, through the design that the flow guide plates are matched with the air bags, the flow amount of fluid is adjusted through convergence or divergence of the flow guide plates, and accordingly flow adjustment is more stable and smoother.

Description

technical field [0001] The invention relates to the technical field of flow regulating valves, in particular to a converging and diverging spout regulating valve. Background technique [0002] As we all know, the flow regulating valve, also known as flow control valve, flow controller, dynamic balance valve, flow balance valve, is a valve device that realizes the flow regulation and control of fluid medium. [0003] Generally speaking, for regulating valves, its regulating function is obviously the most important; the technical requirements for the design of general flow regulating valves are: the regulating valve is required to operate smoothly when it is working, the opening is relatively small, the regulating performance is good, and it can meet the required flow rate. Features, small flow resistance, large flow ratio, fast adjustment speed and other technical characteristics. [0004] In a specific application, when the fluid medium flows through the pipeline system, fl...
