Description
Technical field
The present invention relates to a kind of modulating valve, specifically a kind of novel low noise flow control valve.
Background technique
As everyone knows, because the health of noise on human body is harmful to, need the intensity managing to limit the noise that commercial plant produces.Modulating valve is noise source important in the commercial plants such as oil refining, chemical industry.Modulating valve is made up of actuator and valve part 2 part.Actuator is the drive unit of modulating valve, and it produces corresponding thrust by the size of signal pressure, makes push rod produce corresponding displacement, thus the action of band movable valve plug; Valve part is the adjustment portion of modulating valve, direct and medium contact, by the displacement of actuator's push rod, changes the orifice size of modulating valve, reaches the object of adjustment, and it is also the main occurring source of noise simultaneously.Noise pollution has become one of universally acknowledged 4 large pollution sources, and each state all drops into huge fund noise control, and people have higher requirement to Noise measarement.Modulating valve is usually the noise source in pipe-line system, when pressure drops to certain critical value, easily causes air pocket, cavitation phenomenon, and with flow noise and vibration.Modulating valve flow passage structure affects the key factor that modulating valve produces noise; Therefore, be necessary to the research of regulating valve structure.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of novel low noise flow control valve.
The present invention is achieved through the following technical solutions: a kind of low noise flow control valve, comprises valve body and is arranged on the valve cage in valve body;
Described valve body comprises the annular pass and spherical channel of building up and down together, and is sealed in the valve gap of upper end, annular pass; Described spherical channel I side has import, and side, described annular pass has outlet;
Described valve cage is cylindrical tube shape, and have multiple axial long through-hole within the scope of valve cage cylindrical wall 270-300 degree, valve cage lower end is fixed with supporting element; Valve cage is arranged in annular pass and spherical channel, is communicated with annular pass and spherical channel;
The total part of core bar is installed in described valve cage; The total part of described core bar comprises the controlling rod running through described valve gap; Coordinate in described valve cage and the push pedal be connected with controlling rod is installed; The spiral spring sheet be provided with between described supporting element and push pedal is also coordinated in valve cage;
Damping hairbrush is provided with in the ring runner formed between described valve cage cylindrical outer wall and annular pass.
It is further: the cylindrical wall that described outlet and valve cage do not open long through-hole is relative.
Described import comprises the cylindrical tube passage I being communicated with spherical channel; Described cylindrical tube passage I end is provided with adpting flange I.
Described outlet comprises the cylindrical tube passage II being communicated with annular pass; Described cylindrical tube passage II end is provided with adpting flange II.
Described spiral spring sheet axis valve cage axial alignment.
During work, promote push pedal by controlling rod and compress spiral adjustable elastic sheet, change spiral spring sheet gap size to realize Flow-rate adjustment.Because fluid is first reduced pressure by gap, fluid is diminished by the turnover pressure reduction of valve cage long through-hole, and the long through-hole sectional area that valve cage is arranged is constant, realizes Flow-rate adjustment, reduces through-flow noise; Simultaneously on valve cage, perforate is uniformly distributed within the scope of 270 degree, does not just have perforate to valve outlet place, and is provided with cylindrical damping hairbrush in ring runner between valve body and valve cage, further improves exit flow field flow characteristic, reduces through-flow noise further.
Structure of the present invention is simple, Imbalance in weight power is little, good stability, not easy to wear, not easily vibrate, low, the easy regulable control of noise, improves the phenomenon that mechanical vibration produce noise.
