The utility model discloses the intraductal rivers vertical falling of major structure opposition gets into has very big buffering energy dissipation effect when violently managing, reduce hydraulic jump and noise. The air current is not smooth in can further solving the elbow through guide vanes in addition, problem that the drainage noise is big.
Description
Technical field
The application belongs to construction drainage technical field, more particularly to a kind of riser bottom elbow.
Background technology
Continuous reinforcement with people's environmental consciousness and raising, pursue high-quality, high-grade living environment and inhabitation ring
Border comes into fashion.Thus, the draining noise of construction drainage tubing becomes currently focus of concern.
The noise of construction drainage tubing, is to produce integrated noise in flow process by the different fluid in pipeline.
One of its influence factor is in soil stack bottom corner, and different fluid is from vertical flowing steering horizontal to flow process
In, not only can produce collision between fluid, and produce noise；Meanwhile, the current in standpipe under gravity, also can impact vertical
The tube wall of bottom of the tube, produces vibration and makes a noise；Further, the water droplet that a part is repelled also can produce with rear current extremely and hit
Hit and trigger noise.
Existing soil stack bottom elbow, current and air turbulence, mutually clash into, and current are not smooth.Meanwhile, current with
Airflow strikes noise is big.It is not suitable for the single-stack drain system of low noise, needs to carry out technological improvement.
Utility model content
The purpose of this utility model is to provide a kind of riser bottom elbow, to overcome deficiency of the prior art.
For achieving the above object, the following technical scheme of this utility model offer:
The embodiment of the present application discloses a kind of riser bottom elbow, including standpipe interface, transverse tube interface, the first main body tube,
Two main body tubes and the 3rd main body tube, described first main body tube, the second main body tube and the 3rd main body tube are sequentially connected to described standpipe
Between interface and transverse tube interface, described standpipe interface, transverse tube interface, the first main body tube, the second main body tube and the 3rd main body tube
Joint curvature mutation, described second main body tube is horizontally disposed with, and the bore of described transverse tube interface is more than the mouth of described standpipe interface
Footpath.
Preferably, in above-mentioned riser bottom elbow, described first main body tube axis and horizontal direction angle are 45 °.
Preferably, in above-mentioned riser bottom elbow, described first main body tube is identical along its axial internal diameter.
Preferably, in above-mentioned riser bottom elbow, described second main body tube is identical along its axial internal diameter.
Preferably, in above-mentioned riser bottom elbow, the axis of described 3rd main body tube is located at horizontal direction, and the 3rd
To transverse tube interface, gradually property increases interior second main body tube without leave of main body tube.
Preferably, in above-mentioned riser bottom elbow, the bottom of described first main body tube is fixed with perpendicular positioning support.
Preferably, in above-mentioned riser bottom elbow, in described standpipe interface, it is provided with guide vane.
Compared with prior art, the utility model has the advantage of:
This utility model agent structure opposes and has very big buffering energy dissipating work when in-pipe flow vertical drop enters transverse tube
With reducing hydraulic jump and noise.Can solve additionally by guide vane that elbow interior air-flow is not smooth further, big the asking of drainage noise
Topic.
Brief description
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 show the sectional view of this utility model specific embodiment neutrality bottom of the tube elbow.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Detailed description is it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole enforcement
Example.Based on the embodiment in this utility model, those of ordinary skill in the art institute on the premise of not making creative work
The every other embodiment obtaining, broadly falls into the scope of this utility model protection.
In conjunction with shown in Fig. 1, riser bottom elbow, including standpipe interface 1, transverse tube interface 2, the first main body tube 3, the second main body
Pipe 4 and the 3rd main body tube 5, the first main body tube 3, the second main body tube 4 and the 3rd main body tube 5 are sequentially connected to standpipe interface 1 and horizontal stroke
Between interface tube 2, standpipe interface 1, transverse tube interface 2, the joint of the first main body tube 3, the second main body tube 4 and the 3rd main body tube 5
Curvature mutation, the second main body tube 4 is horizontally disposed with, and the bore of transverse tube interface 2 is more than the bore of standpipe interface 1.
Preferably, the first main body tube 3 axis and horizontal direction angle are 45 °.
Further, the first main body tube 3 is identical along its axial internal diameter.
Further, the second main body tube 4 is identical along its axial internal diameter.
Further, the axis of the 3rd main body tube 5 is located at horizontal direction, interior second main body without leave of the 3rd main body tube 5
To transverse tube interface 2, gradually property increases pipe 4.
Further, the bottom of the first main body tube 3 is fixed with perpendicular positioning support 6.
In this technical scheme, perpendicular positioning support facilitates implementation the quick location and installation of elbow, and improve fastness and
Stability.
Further, it is provided with guide vane 7 in standpipe interface 1.
In this technical scheme, current can be separated by guide vane effectively with air-flow, to keep empty in soil stack
Gaseous core post connect inertia up and down, make the air pressure in standpipe be in more stable state, thus it is unimpeded with air-flow to reach current, gas
The low purpose of pressure fluctuation.
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation are made a distinction with another entity or operation, and not necessarily require or imply these entities or deposit between operating
