A New Throttle Hedge Type Pressure Reducing and Speed ​​Control Regulating Valve

Abstract

The invention belongs to the related technical field of pressure regulating valves, and discloses a novel throttling hedging type decompression and speed control regulating valve. The diversion sleeve, the bonnet is connected to the valve body; one end of the valve rod extends into the valve body after passing through the bonnet, which is used to drive the movement of the new sleeve type spool; the new sleeve type spool is connected One end of the valve rod located in the valve body is located between the throttling assembly and the flow guide sleeve; the flow guide sleeve is accommodated in the valve body, and the throttle assembly part is housed in the guide sleeve; the throttling assembly includes a plurality of space corner throttling elements, and multiple sets of throttling channels are formed in the space corner throttling elements, and a plurality of throttling channels They communicate with each other along the axial direction of the space corner throttling element. The invention improves the effects of pressure reduction and energy consumption, and consumes the kinetic energy of the medium to effectively control the flow rate of the medium in the pressure reduction element.

Description

technical field [0001] The invention belongs to the related technical field of pressure regulating valves, and more specifically relates to a novel throttling and offset pressure reducing and speed control regulating valve. Background technique [0002] The control valve is a control device widely used in high temperature and high pressure fields such as power stations, metallurgy, and petrochemicals. Its main function is to adjust parameters such as pressure, flow, temperature, and liquid level. In the automatic control of modern factories, regulating valves play a very important role, and the production process depends on the correct distribution and control of the flowing medium. These controls include processes such as energy exchange and pressure reduction. These control processes need to be completed by regulating valves. The sudden reduction of the flow area will cause the flow rate of the medium to rise rapidly, which will cause smooth marks on the metal surface of ...

AI Technical Summary

Problems solved by technology

These controls include processes such as energy exchange and pressure reduction. These control processes need to be completed by regulating valves. The sudden reduction of the flow area will cause the flow rate of the medium to rise rapidly, which will cause smooth marks on the metal surface of the regulating valve, causing problems such as vibration and noise

[0003] Under this working condition, severe fluctuations in medium pressure and speed will cause severe vibration and noise, resulting in shortened service life of the regulating valve; under this working condition, the medium is prone to flashing and cavitation, and flashing and cavitation will affect the metal material of the regulating valve. Serious damage will affect the normal operation and service life of the control valve
