Description
Technical field
The present invention relates to a kind of regulating valve, specifically a kind of new low noise flow control valve.
Background technology
It is well known that because the health of noise on human body is harmful, it is necessary to try to limit noise caused by commercial plant
Intensity.Regulating valve is noise source important in the commercial plants such as oil refining, chemical industry.Regulating valve is by executing agency and valve part 2
Part forms.Executing agency is the drive device of regulating valve, and it produces corresponding thrust by the size of signal pressure, produces push rod
Raw corresponding displacement, so as to be acted with movable valve plug；Valve part is the regulation part of regulating valve, directly contacts, passes through with medium
The displacement of executing agency's push rod, change the orifice size of regulating valve, reach the purpose of regulation, while it is also the main hair of noise
Source of students.Noise pollution has become one of big pollution sources in universally acknowledged 4, and each state all puts into huge fund noise control, and people are to making an uproar
Acoustic control proposes higher requirement.Regulating valve is often the noise source in pipe-line system, when pressure drops to certain critical value,
Easily cause air pocket, cavitation, and with flow noise and vibration.Regulating valve flow passage structure is to influence regulating valve to produce noise
Key factor；Therefore, the research to regulating valve structure is necessary.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of new low noise flow control valve.
The present invention is achieved through the following technical solutions：A kind of low noise flow control valve, including valve body and installed in valve body
Interior valve cage；
The valve body includes building circular passage and spherical channel together up and down, and is sealed in circular passage upper end
Bonnet；The spherical channel side is provided with import, and the circular passage side is provided with outlet；
The valve cage is in cylindrical tube shape, and valve cage cylindrical wall is minimum 270 degree, it is multiple axial to be provided with the range of 300 degree of maximum
Long through-hole, valve cage lower end are fixed with support member；Valve cage is arranged in circular passage and spherical channel, connects circular passage and spherical
Passage；
Core bar total part is installed in the valve cage；The total part of described core bar includes the control-rod through the bonnet；It is described
Coordinate the push pedal for being provided with and being connected with control-rod in valve cage；Also coordinate in valve cage be provided with positioned at the support member and push pedal it
Between spiral flexure strip；
Damping hairbrush is provided with the annular channel formed between the valve cage cylindrical outer wall and circular passage.
It is further：The cylindrical wall that long through-hole is not opened in the outlet with valve cage is relative.
The import includes the cylinder tube passage I of connection spherical channel；The end of cylinder tube passage I is provided with adpting flange
Ⅰ。
The outlet includes connecting the cylinder tube passage II of circular passage；The end of cylinder tube passage II is provided with connection method
Orchid II.
The spiral flexure strip axis aligns with valve cage axis.
During work, promote push pedal to compress spiral regulation elasticity piece by control-rod, it is big to change spiral flexure strip gap
It is small to realize Flow-rate adjustment.Because fluid first passes through gap decompression, the disengaging pressure difference for enabling flow through valve cage long through-hole diminishes, valve
The long through-hole sectional area set on cage is constant, realizes Flow-rate adjustment, reduces through-flow noise；Simultaneously on valve cage perforate in 270 degree of models
It is uniformly distributed in enclosing, does not have perforate at face valve outlet, and cylinder is provided with the annular channel between valve body and valve cage
Form drag Buddhist nun's hairbrush, further improves exit flow field flow behavior, further reduces through-flow noise.
The present invention is simple in construction, Imbalance in weight power is small, stability is good, it is not easy to wear, be not easy to vibrate, noise is low, easy tune
Section control, improve the phenomenon that mechanical oscillation produce noise.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with accompanying drawing, the invention will be further described.
As shown in figure 1, valve body 1 includes building circular passage 1.2.3 and spherical channel 1.1.3 together up and down, annular is logical
Road 1.2.3 upper ends are fixed with bonnet 1.3；Spherical channel 1.1.3 sides are provided with import 1.1, and import 1.1 includes connection spherical channel
