Description
Technical field
This utility model relates to cylinder, is specifically related to a kind of supply air line dividing potential drop cylinder.
Background technology
Industrial premises often needs to install the process gas pipelines such as jet chimney, compressed air piping, ozone pipeline; the design of process gas pipeline is usually according to the size using the consumption of point, flow velocity etc. to determine pipeline; pipeline uniform distribution in use is not considered; particularly when the caliber of main trachea is less; the flow velocity of gas is very big, often there will be the situation that pressure distribution is uneven in numerous arms.
Utility model content
The purpose of this utility model is in that to provide a kind of supply air line dividing potential drop cylinder, solves a problem that pipe pressure distribution is uneven in supply air line, improves the harmony of air pressure in whole supply air line.
This utility model is achieved through the following technical solutions:
A kind of supply air line dividing potential drop cylinder, including horizontally disposed cylinder body and the main trachea being connected with cylinder body bottom, multiple bronchus being connected with cylinder body top, being provided with two spiral protrusions along described cylinder body axis direction wall within it, two described spiral protrusions are arranged oppositely and lay respectively at the both sides of main air pipe outlet.For in prior art, main trachea with numerous bronchus when being connected, particularly when the caliber of main trachea is less, main tracheorrhaphy is assigned to intrabronchial gas, and to be subject to the impact of air velocity size comparatively serious, when in main trachea, flow velocity is bigger, less along the gas flow flowing in the bronchus that direction is connected at first distribution with main trachea of gas, and along gas to flow to the gas flow distributed in the bronchus that direction is finally connected with main trachea bigger, and then cause that the air pressure in whole bronchus pipeline is unbalanced, it is unfavorable for the gas supply conveying in whole supply air line；This utility model installs one between numerous bronchus and main trachea can carry out the cylinder body that gas is temporary, when in main trachea, gas flow rate is bigger, the gas in cylinder body is entered into by main air pipe outlet, in its generation air pressure change after the change suddenly of free air space is big, namely gas flow rate reduces accordingly；nullAnd enter into the air-flow within cylinder body and form corresponding laminar flow by the bounce-back of cylinder body inwall，And start to carry in each bronchus along inwall，But at air-flow after reduction of speed，Air-flow fluid layering flows，Cannot produce along cylinder body motion vector in the radial direction，Namely the gas flow entered in bronchus is relatively small，It is unable to reach gas and flows quickly through the purpose of whole supply air line，And this utility model is provided with spiral protrusion in the both sides of main air pipe outlet，The air-flow entering in cylinder body is made to realize the transformation of laminar flow and wadding stream by spiral protrusion，There are many whirlpools in the flow field that now this air-flow is formed，Laminar flow is destroyed，Fluid does irregular movement，The component velocity simultaneously producing to be perpendicular to cylinder body axis direction produces，Namely air-flow can along the inwall of cylinder body successively mobile extremely each bronchus，And the eddy flow flow velocity that gas is formed is faster，Without considering the gas distribution that each bronchial sorting position can realize in cylinder body，Solve a problem that pipe pressure distribution is uneven in supply air line，Improve the harmony of air pressure in whole supply air line.
The two ends of described cylinder body are provided with ring flange.Cylinder body two ends are arranged to ring flange connect so that cylinder body directly can be carried out fast assembling-disassembling by staff, and it is carried out scarfing cinder operation, to avoid the residue produced after cylinder body uses for a long time by main trachea or bronchial obstruction.
Multiple described bronchus equi-spaced apart are arranged on described cylinder body, and adjacent two described bronchial spacing are 8 ~ 10.As preferably, multiple bronchus equi-spaced apart are arranged on cylinder body, can further improve the gas in cylinder body more balanced when being allocated, it is prevented that the fluency of supplying gas of whole supply air line is impacted by the negative pressure that each bronchial air inlet place is formed in various degree.And, two adjacent bronchial spacing are arranged in 8 ~ 10 scopes, under the premise being unaffected each other when ensureing and installing each quasi-instrument or valve in bronchus, also ensure that the gas in cylinder body is after forming eddy flow, this gas is at full speed proceeded in bronchus, ensures that the supply in each bronchus road is stable.
Described bronchial number is odd number, and described main trachea is arranged on the middle part of cylinder body, is positioned on cylinder body and bronchus that affiliated sequence number is median is just to described main trachea.On cylinder body, the bronchus air inlet being positioned at middle is just right with the gas outlet of main trachea, make gas after entering cylinder body, a part enters directly into this bronchus, reduce the gas impact to cylinder body inwall, remaining gas then sequentially enters in remaining bronchus along cylinder inner wall, and then improves the service life of cylinder body.
Successively decrease in the direction that the internal diameter of described spiral protrusion points to its two ends along cylinder body center.The hand of spiral of spiral protrusion is to point to the direction at its two ends along cylinder body center, and gas is entering after in cylinder body, its free air space suddenly become big after, corresponding flow velocity will reduce；And successively decrease in the direction that the internal diameter of spiral protrusion points to its two ends along cylinder body center, namely the gas in cylinder body is through spiral protrusion, its free air space is made suddenly to reduce again, corresponding flow velocity will increase, and gas improves accordingly along the component velocity being perpendicular on cylinder body axis direction, and then ensure that the transfer of gas flowed in each bronchus is more smooth.
This utility model compared with prior art, has such advantages as and beneficial effect:
1, this utility model is provided with spiral protrusion in the both sides of main air pipe outlet, the air-flow entering in cylinder body is made to realize the transformation of laminar flow and wadding stream by spiral protrusion, there are many whirlpools in the flow field that now this air-flow is formed, laminar flow is destroyed, fluid does irregular movement, the component velocity simultaneously producing to be perpendicular to cylinder body axis direction produces, namely air-flow can along the inwall of cylinder body successively mobile extremely each bronchus, and the eddy flow flow velocity that gas is formed is faster, without considering the gas distribution that each bronchial sorting position can realize in cylinder body, solve a problem that pipe pressure distribution is uneven in supply air line, improve the harmony of air pressure in whole supply air line；
2, cylinder body two ends are arranged to ring flange connection by this utility model, make staff directly cylinder body can be carried out fast assembling-disassembling, it is carried out scarfing cinder operation, to avoid the residue produced after cylinder body uses for a long time by main trachea or bronchial obstruction；
3, this utility model is on cylinder body, the bronchus air inlet being positioned at middle is just right with the gas outlet of main trachea, make gas after entering cylinder body, a part enters directly into this bronchus, reduce the gas impact to cylinder body inwall, remaining gas then sequentially enters in remaining bronchus along cylinder inner wall, and then improves the service life of cylinder body.
