Description

Novel low noise flow control valve
Technical field
The present invention relates to a kind of regulating valve, specifically a kind of novel 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 the noise produced by commercial plant Intensity.Regulating valve is important noise source in the commercial plants such as oil refining, chemical industry.Regulating valve is by executing agency and valve part 2 Part constitutes.Executing agency is the drive device of regulating valve, and the size that it presses signal pressure produces corresponding thrust, produces push rod The corresponding displacement of life, so that band movable valve plug action;Valve part is the regulation part of regulating valve, is directly contacted with medium, is passed through The displacement of executing agency's push rod, changes the orifice size of regulating valve, the purpose of regulation is reached, 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 requirement higher.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 that influence regulating valve produces noise Key factor;Therefore, the research to regulating valve structure is necessary.
The content of the invention
It is an object of the invention to provide a kind of noise is low, simple structure, the novel low noise of not easy to wear, easy regulation control Flow control valve.
The present invention is achieved through the following technical solutions:A kind of novel low noise flow control valve, including valve body, installed in valve Internal valve cage and the total part of the core bar in valve cage;
Described 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, 270 ° -300 of valve cage cylindrical wall0In the range of be provided with the through holes of multiple axial directions, on valve cage The cylindrical wall inner side of non-opened hole is provided with axial deep gouge;Valve cage lower end is fixed with support member;Valve cage is arranged in circular passage, Connection circular passage and spherical channel;
The total part of described core bar includes the control-rod and the flexure strip for being rolled into annular shape through the bonnet;The control-rod On valve cage axial centerline, control-rod the inner may be rotatably mounted on support member, be opened on the control-rod in valve cage There is axial deep gouge;The flexure strip is wound on control-rod surrounding, in the deep gouge on the inside of flexure strip one end insertion valve cage cylindrical wall, separately In one end insertion control-rod deep gouge, the axial length of the width more than valve cage through hole of flexure strip;
Damping hairbrush is provided with the annular channel formed between the valve cage cylindrical wall and circular passage.
It is further:The outlet is relative with the cylindrical wall of the non-opened hole of valve cage.
The import includes the cylinder tube passage of connection spherical channel;The cylindrical tube channel end is provided with adpting flange I.
The outlet includes connecting the cylinder tube passage of circular passage;The cylindrical tube channel end is provided with adpting flange Ⅱ。
The flexure strip original state is close to valve cage inwall.
During work, flexure strip is controlled to adjust by control-rod rotational angle with the gap size of valve cage inwall to realize stream Amount regulation.Because fluid first passes through gap decompression, the turnover pressure difference for enabling flow through valve cage through hole diminishes, and what is set on valve cage goes out Mouth sectional area is constant, in the case of realizing regulation flow, reduces noise;Perforate uniformly divides in the range of 270 degree on valve cage simultaneously Cloth, just to not having perforate at valve outlet, and is provided with cylinder damping hairbrush in valve outlet annular channel, further changes It has been apt to exit flow field flow behavior, has further reduced noise size.The Imbalance in weight power is small, good stability, be difficult vibration, from And largely improve the phenomenon that mechanical oscillation produce noise.

Specific embodiment
The following is a specific embodiment of the invention, in conjunction with accompanying drawing, the invention will be further described.
As shown in figure 1, a kind of novel low noise flow control valve, valve body 1 including building circular passage together up and down 1.2.2 with spherical channel 1.1.2, and the bonnet 1.3 for being sealed in circular passage 1.2.2 upper ends;Spherical channel 1.1.2 is opened side There is import 1.1, circular passage 1.2.2 sides are provided with outlet 1.2;Import 1.1 includes that the cylindrical tube of connection spherical channel 1.1.2 is led to Road, cylindrical tube channel end is provided with the 1.1.1 of adpting flange I;Outlet 1.2 includes the cylinder tube passage of connection circular passage 1.2.2, Cylindrical tube channel end is provided with the 1.2.1 of adpting flange II.Valve cage 2 is in cylindrical tube shape, is provided with the range of 270 ° of 2 cylindrical wall of valve cage many The individual axial through hole 2.1 being evenly arranged, the cylindrical wall inner side of non-opened hole is provided with axial deep gouge on valve cage 2, outlet 1.2 with The cylindrical wall of the non-opened hole 2.1 of valve cage 2 is relative;The lower end of valve cage 2 is fixed with support member 2.2;Valve cage 2 is arranged on circular passage 1.2.2 it is interior, connect circular passage 1.2.2 and spherical channel 1.1.2.Formed between the cylindrical wall of valve cage 2 and circular passage 1.2.2 Damping hairbrush 4 is provided with annular channel, damping hairbrush 4 is cylinder, is converted into ring-type and is fitted into annular channel.Spherical channel 1.1.2 interior liquid passes through inside support member 2.2, valve cage 2, the through hole 2.1 of valve cage 2 is entered into annular channel, then passes through Mouth 1.2 flows out.With reference to shown in Fig. 2, the total part 3 of core bar includes the control-rod 3.1 and the bullet for being rolled into annular shape through the bonnet 1.3 Property piece 3.2, control-rod 3.1 be located at the axial centerline of valve cage 2 on, the inner of control-rod 3.1 may be rotatably mounted at support member 2.2 On, it is provided with axial deep gouge on the control-rod 3.1 in valve cage 2;Flexure strip 3.2 is wound on the surrounding of control-rod 3.1, flexure strip In deep gouge on the inside of 3.2 one end insertion cylindrical wall of valve cage 2, in the other end insertion deep gouge of control-rod 3.1, the width of flexure strip 3.2 More than the axial length of the through hole 2.1 of valve cage 2, the original state of flexure strip 3.2 is close to the inwall of valve cage 2, prevents liquid from passing through through hole 2.1 Outflow;
During work, control-rod 3.1 rotates a certain angle, scrolling flexure strip 3.2, the inwall shape of flexure strip 3.2 and valve cage 2 Into gap, fluid is entered in annular channel by the through hole 2.1 set on gap and valve cage 2, then is flowed out by outlet flow.It is logical The size in gap between the anglec of rotation regulation elasticity piece 3.2 and the inwall of valve cage 2 that change control-rod 3.1 is crossed to adjust flow.
