Problems solved by technology

[0002] With the development and progress of industrial production, there are more and more applications of high-pressure differential control in the field of fluid control. However, under the high-pressure differential condition of the control valve, the fluid flow rate in the valve flow channel is too high, resulting in erosion, cavitation, etc. Vibration, noise and other serious problems lead to damage and failure of valve components, shortened service life, and reduced reliability of the entire system, posing a major safety hazard to safe production with efficient and stable operation

Abstract

The invention discloses a labyrinth disc of a high-pressure-difference pressure-reducing and noise-reducing control valve, a plurality of rotary labyrinth type channels are arranged on the labyrinth disc, each rotary labyrinth type channel comprises an inlet section, a pressure-reducing and noise-reducing section and an outlet section, and the inlet section and the outlet section are straight channels in the diameter direction of the round disc. Wherein the pressure reduction and noise reduction section comprises a plurality of semicircular and straight section combined double-convolution bent channels which alternately generate left and right; on the premise that flow required by working conditions is met, more efficient and stable pressure and noise reduction effects are achieved, the phenomena of cavitation, noise and vibration are effectively prevented, damage such as cavitation and scouring is avoided, the medium flow speed is greatly and stably reduced, and the maintenance period and the service life of the valve are prolonged.

Description

technical field [0001] The invention relates to a labyrinth disc, in particular to a labyrinth disc for a high pressure difference pressure reducing noise reduction control valve, which belongs to the technical field of valve installation. Background technique [0002] With the development and progress of industrial production, there are more and more applications of high-pressure differential control in the field of fluid control. However, under the high-pressure differential condition of the control valve, the fluid flow rate in the valve flow channel is too high, resulting in erosion, cavitation, etc. Vibration, noise and other serious problems lead to damage and failure of valve components, shortened life span, and reduced reliability of the entire system, posing a major safety hazard to safe production with efficient and stable operation. [0003] For the control valves that are suitable for high pressure differential conditions, there are mainly two countermeasures for...
