Abstract
A kind of ventilation water conservancy diversion elbow, for installing between the turning of ventilation shaft and straight tube, it is characterized in that the elbow is made of cylinder, deflector, connecting flange；Cylinder both ends are respectively connected with connecting flange, and cylinder bore is fixedly connected with deflector.The present invention can lengthen guide flow path, reduce resistance, reduce noise, so that stream swirl is disappeared, be smoothly transitioned into the straight pipe of lower wind direction.The water conservancy diversion elbow is cylindrical structure, between the straight tube of the turning for installing ventilation shaft, plays the role of transitional flow.
Description
Technical field
The invention belongs to environment protection fields.More particularly to a kind of ventilation water conservancy diversion elbow, it is mainly used in the air pipeline of air duct, makees
For a part of air duct ventilation equipment.
Background technique
Existing ventilation air duct pipeline is because path is longer, and generally directly turning transition, is caused when space trend needs to change
Gas generates vortex in managing, and resistance increases, and influences the flowing of gas, generates noise, further increases active blowing device
Difficulty and consumption.Existing water conservancy diversion elbow is only axially inwardly to be fixed with a plurality of bar shaped water conservancy diversion in the end face of straight pipe and bend loss
Plate, a plurality of bar shaped deflector are in parastate, and this structure only can play guide functions in wind inlet section, arrive corner and outlet air
Duan Shi, air-flow restart disorder, generate vortex.Another water conservancy diversion elbow be provided on the inner wall of interlude connector to
A few arc-shaped guide rib.It is this to be flowed with stabilizing gas, impact of the air-flow to equipment is reduced, but only in bend pipe
Section works, and mainly increases the resistance of air-flow, reduces air velocity, cannot effective water conservancy diversion, reduce the disorder and vortex of air-flow.
Summary of the invention
To solve the problems, such as that deflector curtailment and effect are poor, the present invention provides a kind of ventilation water conservancy diversion elbows, this is curved
Head guide flow path is long, can reduce flow velocity resistance and impact force, the vortex of air-flow is made to disappear, and then reduces noise, reduces energy damage
It loses, is smoothly transitioned into the straight pipe of lower wind direction.
A kind of ventilation water conservancy diversion elbow, for installing between the turning of ventilation shaft and straight tube, it is characterized in that the elbow by
Cylinder, deflector, connecting flange composition；Cylinder both ends are respectively connected with connecting flange, and cylinder bore is fixedly connected with deflector.
The annulus unit is wedge-shaped annulus, and the one side of the wedge shape annulus is narrow compared with another side；Wide face is located at bend pipe
Convex back position, leptoprosopy are located at bend pipe recessed position.
Deflector is the arc panel of corresponding elbow camber, and the curvature of arc panel corresponds to elbow camber.
It is uniformly distributed in cylindrical wall inner deflector along turn direction.
Elbow cylindrical structure is finally formed by the end edge welding of several annulus units.In a practical situation according to turning angle
Degree chooses the elbow that annulus element number is welded into different cambers.Cylindrical wall plays connection both ends straight pipe, supporting guide plate
Effect.
Connecting flange is an annulus, is made by steel plate, the diameter of flange corresponds to the diameter of cylinder.Have on annulus several
Circular hole is installed.A pair of of connecting flange is respectively welded at straight tube and elbow end, integrally mounted using bolt fastening.
Deflector is formed by rectangle steel plate roller circle, is become the arc panel of corresponding elbow camber, is placed according in cylindrical wall
Position difference is divided into middle deflector and side deflector.Middle deflector is in the middle part of elbow, barrel of the side deflector close to elbow.
The present invention can lengthen guide flow path, reduce resistance, reduce noise, so that stream swirl is disappeared, be smoothly transitioned into
The straight pipe of lower wind direction.The water conservancy diversion elbow is cylindrical structure, between the straight tube of the turning for installing ventilation shaft, plays transition
The effect of air-flow.

Specific embodiment
Shown in Fig. 1, a kind of ventilation water conservancy diversion elbow, the water conservancy diversion elbow is cylindrical structure, is mounted on the straight of ventilation shaft turning
Between pipeline section, play the role of transitional flow.
Shown in Fig. 2, water conservancy diversion elbow 2 is made by 5mm thick steel plate, and forming diameter 600mm by cylindrical wall 22, is led
Flowing plate, connecting flange 21 form.
22 internal diameter of cylindrical wall is 600mm, and cylindrical wall both ends are welded with connecting flange 21, are welded with 3 in cylindrical wall inner cavity
Block deflector, 3 pieces of deflectors are evenly spaced on along turn direction.
The cylindrical wall is formed by connecting by several wedge-shaped annulus.
Shown in Fig. 3, the convex back of wedge-shaped annulus is wide compared with concave surface.
In actual use according to angle of turn, such as 90 ° are chosen 5, and 120 ° of selections, 3 annulus units are welded into different curved
The elbow of degree.Cylindrical wall plays the role of connecting both ends straight pipe, supporting guide plate.
Connecting flange is a diameter 600mm, and the annulus of wide 20mm is made by 5mm thick steel plate.Have on annulus 12 it is straight
The installation connected circular hole of diameter 8mm.A pair of of connecting flange is respectively welded at straight tube and elbow end, is mounted to one using M6 bolt fastening
Body.
Deflector is formed by rectangle 5mm thick steel plate roller circle, becomes the arc panel of corresponding elbow camber, according in cylindrical wall
Placement location difference is divided into middle deflector 23 and side deflector 24.Middle 23 length and width dimensions of deflector are 1200 × 600mm, and setting exists
The middle part of elbow, side deflector 24 are rolled there are two types of the rectangular steel plates of specification, be respectively 800 × 430 mm steel plate,
The steel plate of 1400 × 430mm, the side deflector of the steel plate bending of 800 × 430 mm are positioned close to inner side of elbow barrel, and 1400
The side deflector of the steel plate bending of × 430mm is positioned close to elbow outside cylinder wall.
