Abstract
The utility model provides a major arc reducing elbow used for drainage in buildings, which comprises a standpipe joint, a cross pipe joint and an elbow body. The major arc reducing elbow is characterized in that the inner diameter Phi (1) of the cross pipe joint is larger than the aperture Phi (2) of the standpipe joint. The central curvature radius R of the elbow body ranges from 150 millimeters to 500 millimeters. The proposal not only plays a role in decelerating the falling water in the standpipe, but also concentrates and releases the air carried in the sewage, thus reducing the normal pressure in the standpipe, eliminating the hydraulic jump and reducing the noise resulting from water flow. As the curvature radius of the elbow body is large, the water vertically falling down in the standpipe to enter the cross pipe is amortized and damped, thus further reducing hydraulic jump.
Description
Technical field
The utility model relates to the construction drainage pipe joint, particularly relates to a kind of big radian reducing elbow of used in construction drainage single-stack drain system, belongs to the building pipe fitting.Be used to improve the architectural drainage system operating mode, have energy dissipating, improve venting capacity and stablize pipeline pressure, eliminate hydraulic jump and form reduction current noise.
Background technique
Carrying a large amount of air in the neutral in-pipe flow vertical drop of architectural drainage system meeting moves downward together, its sewage has bigger kinetic energy, after entering transverse tube, owing to change to flow to and produce hydraulic jump, the interior water level of pipe rises suddenly and is full of conduit section, gas can not free-flow, and transverse tube pressure increases suddenly in the short time, has a strong impact on the safe and smooth of drainage system.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of architectural drainage system operating mode of improving is provided, make the standpipe current enter transverse tube and have energy dissipating, improve venting capacity and stablize pipeline pressure, eliminate hydraulic jump and form the big arc reducing elbow of used in construction drainage that reduces the current noise.
The technological scheme of the big arc reducing elbow of the utility model used in construction drainage is: comprise standpipe interface, transverse tube interface and elbow main body, it is characterized in that the internal diameter Φ of described transverse tube interface
1Aperture Φ greater than the standpipe interface
2, the curvature of centre radius R of described elbow main body is 150～500 millimeters.
The big arc reducing elbow of used in construction drainage of the present utility model, the internal diameter Φ of its transverse tube interface
1Aperture Φ greater than the standpipe interface
2Thereby, in the elbow main body, form enough spaces, both can play decelerating effect to the standpipe falling water flow, air entrained in the sewage can be gathered, discharge again, can reduce malleation intensity in the pipe, eliminate hydraulic jump and form, reduce the current noise; The curvature of centre radius R of its elbow main body is 150～500 millimeters, because radius of curvature is big, has very big buffering energy dissipating effect when the current vertical drop in the standpipe is entered transverse tube, further reduces hydraulic jump and forms.
The big arc reducing elbow of used in construction drainage of the present utility model is shaped on the Vertical location support on the outer wall of its elbow main body, be convenient to quick and precisely install, and improve soundness and stability.The internal diameter Φ of its described transverse tube interface
1Be 160～200 millimeters, the aperture Φ of standpipe interface
2It is 110～160 millimeters.Its standpipe interface and the transverse tube interface flexible apparatus of respectively doing for oneself is connected.Its standpipe interface is respectively done for oneself bonding mouthful with the transverse tube interface and is connected.

Fig. 2 is the sectional view of the big arc reducing elbow of the utility model used in construction drainage (flexibly connecting).
Embodiment
The utility model relates to a kind of big radian reducing elbow of used in construction drainage single-stack drain system, as shown in Figure 1 and Figure 2, comprise standpipe interface 1, transverse tube interface 4 and elbow main body 2, standpipe interface 1 connects standpipe, transverse tube interface 4 connects transverse tube, standpipe interface 1 is connected by elbow main body 2 with transverse tube interface 4, it is characterized in that the internal diameter Φ of described transverse tube interface 4
1Aperture Φ greater than standpipe interface 1
2, the curvature of centre radius R of described elbow main body 2 is 150～500 millimeters.Compared with the prior art this programme has following advantage: 1, the internal diameter Φ of its transverse tube interface 4
1Aperture Φ greater than standpipe interface 1
2Thereby, in elbow main body 2, form enough spaces 3, both can play decelerating effect to the standpipe falling water flow, air entrained in the sewage can be gathered, discharge again, can reduce malleation intensity in the pipe, eliminate hydraulic jump and form, reduce the current noise; 2, the curvature of centre radius R of its elbow main body 2 is 150～500 millimeters, because radius of curvature is big, has very big buffering energy dissipating effect when the current vertical drop in the standpipe is entered transverse tube, further reduces hydraulic jump and forms.Be shaped on Vertical location support 5 on the outer wall of its elbow main body 2, be convenient to quick and precisely install, and improve soundness and stability.In actual manufacture process, Vertical location support 5 can adopt the special process single injection-molded, and once-through easy processing, cost of production are lower.The internal diameter Φ of its described transverse tube interface 4
1Be 160～200 millimeters, the aperture Φ of standpipe interface 2
2It is 110～160 millimeters.Standpipe interface 1 is connected with standpipe, and transverse tube interface 4 connects (as shown in Figure 2) with adopting flexible apparatus 6,7 being connected of transverse tube respectively, also can adopt bonding mouthful 8,9 to connect (as shown in Figure 1).
