Abstract
The utility model discloses a labyrinth noise reduction regulating valve. An upper valve cage, a valve cage component and a valve seat of the regulating valve are positioned between an inlet and an outlet; a stroke indicator is connected to the upper end of a valve rod; the lower end of the valve rod is connected with a valve core component; the valve core component is positioned inside the valve cage component; the valve seat is positioned below the valve cage component; the upper valve cage is positioned above the valve cage component; an upper valve cap is positioned above the upper valve cage; the valve cage component is formed by coinciding labyrinth circular discs; and runner grooves are arranged on each circular disc. Each runner groove is provided with different numbers of corner, contraction and expansion according to different depressurization stage numbers; and crooked road stage number can reach eight and lower noise by 10-80 dB. The labyrinth noise reduction regulating valve has unique right angle and corner fluid passages, depressurizes fluid repeatedly and gradually, and consumes kinetic energy of the fluid. Besides, the labyrinth noise reduction regulating valve is adaptable to harsh and adverse working condition occasions with flash evaporation and cavitation corrosion in industries such as power plant, oil, chemical industry, natural gas and the like.
Description
Technical field
The utility model relates to a kind of modulating valve that is used for industry control High Pressure Difference fluids such as power plant, oil, chemical industry, rock gas.
Background technique
Traditional modulating valve one end is provided with import, and the other end is provided with outlet, and the centre is connected with spool, is connected with the opening type valve cage in the spool.This valve in use, when the valve inner fluid flow through, the noise of generation was bigger.
Summary of the invention
In order to overcome the bigger defective of existing modulating valve noise, the utility model provides a kind of mazy type noise reduction sound modulating valve, and this mazy type noise reduction sound modulating valve noise is little.
The technological scheme that its technical problem that solves the utility model adopts is: this modulating valve comprises valve body, bonnet and valve cage, valve body one end is provided with import, the valve body the other end is provided with outlet, last valve cage, valve cage assembly and valve seat are between import and outlet, the valve rod upper end is connected with travel indicator, the valve rod lower end links to each other with mangetic core assembly, mangetic core assembly is positioned at valve cage assembly, valve seat is positioned at below the valve cage assembly, last valve cage is positioned at above the valve cage assembly, bonnet is positioned at above the valve cage, and valve cage assembly is formed by stacking for the mazy type disk, and disk is provided with runner trench.
The valve cage assembly that the utility model adopts a plurality of mazy type disks to be formed by stacking, process the runner trench of many narrow variations on the disk, each runner trench has the corner of varying number and compression, expansion according to step-down progression difference, these grooves are made meticulous, detour progression can reach 8 grades, can reduce noise 10～80dB.
The utility model volume is little, in light weight, has unique right angle corner stream, and single current road and multithread road mazy passage are arranged, make fluid repeatedly, step-down step by step, consumed the kinetic energy of fluid, reduced flow rate of fluid and noise.
The utility model can match with 812 many springs of type pneumatic diaphragn actuating mechanisms and 824 serial electropneumatic valve positioners and 827 serial novel intelligent type valve positioners, directly accept 4～20mA dc signal that computer is sent, enter actuator film chamber by the valve positioner output pressure, make modulating valve action, precise control.
The utility model is applicable to harsh bad working environments occasion with flash distillation, cavitation erosion and the High Pressure Difference fluid control occasion in the industries such as power plant, oil, chemical industry, rock gas.Thereby the minimizing equipment downtime reduces and safeguards and maintenance cost, increases enterprises' production capacity.
