For example, the Chinese utility model patent that notice of authorization number is CN 203068033U discloses a kind of solid accumulation, obstruction can effectively avoided, and the wear-resistant bend of wear-resisting effective, long service life.Comprise material feeding mouth, discharge port and there is the Curved body of chamber, the back of described body chamber offers protuberance chamber, back, protuberance chamber, described back comprises that the radian in protuberance chamber, described back one is greater than the radian in protuberance chamber, described back two near the protuberance chamber, back two of the protuberance chamber, back one of described discharge port and close described material feeding mouth.
Publication number is that the wear-resistant bend that the Chinese invention patent application of 102720909A discloses a kind of pneumatic transporting ash pipe is by elbow, be buckled in the filling cover composition at elbow outer wall place, elbow is the cavity bend pipe of open at both ends, at the peripheral wall arranged outside fin of elbow axis both sides, fin length is identical with elbow length, and radian is identical with elbow radian, fills cover in elbow projection outer wall outer wrapping, fill cover both sides and be connected with fin, in filling cover, be filled with packing.
In existing UPVC outdoor rain water discharge system and indoor sewage drainage system, its riser bottom is generally connected to form longspan elbow structure with two 45 ° of elbows, then is connected with bottom discharge transverse tube, realizes the draining from soil stack to bottom transverse tube.
Architecture storey is higher, and the kinetic energy that current produce is larger, and the kinetic energy of the foreign matters such as stone is also larger, also larger to the impact force of the large radian elbow structure in bottom.This existing large radian elbow structure, is subject to the impact of current and foreign matter in standpipe, the phenomenon that there will be breaks leaks for a long time.Particularly tall building (33m～100m), common large radian elbow structure cannot bear this impact force completely.
Model utility content
The utility model provides a kind of anti-impact longspan elbow, solves the especially high layer sewerage system Structure of Bottom Large-span of the existing drainage system elbow structure problem of leaking of very easily breaking.
A kind of anti-impact longspan elbow, comprises elbow body, and the inside of described elbow body is provided with anti-impact liner, and the outer wall of described elbow body is provided with stiffening rib.
Anti-impact longspan elbow of the present invention is applied to the especially high layer sewerage system of drainage system, connect soil stack and dewatering horizontal tube, architecture storey is higher, the kinetic energy that current produce is larger, the kinetic energy of the foreign matters such as stone is also larger, also larger to the impact force of Structure of Bottom Large-span elbow structure, elbow structure very easily breaks and leaks, the utility model arranges anti-impact liner in elbow body, first the current or the foreign matter that fall along standpipe inwall contact with anti-impact liner, by weakening the impact force of weight after anti-impact liner buffering, at elbow body, stiffening rib is set outward simultaneously, strengthen the shock resistance dynamics of elbow, inside and outside collaborative, strengthen the intensity of elbow body, effectively avoid breaking of pipe fitting body.
As preferably, the span of described elbow body is 1.5～2.5 times of 90 ° of elbow spans.
Preferably another kind of, the span of described elbow body is the span of two 45 ° of bend-head combination parts.
The span of described elbow refers to the crow flight distance between two terminations of elbow.Described 90 ° of elbows and 45 ° of elbows all refer to the conventional specification elbow in related domain.The standpipe and the transverse tube that connect tall building drainage system for the elbow of this radian scope, connect radian just in time, and it is best that impact resistance also can reach.
In order further to strengthen the buffer function of anti-impact liner, as preferably, described anti-impact liner is close to the inwall setting of described elbow body.
Described anti-impact liner is soft liner.As preferably, described anti-impact liner is flexible PVC liner or elastometric lining.The anti-impact liner of this material has better shock resistance.
For further improving the impact resistance of anti-impact liner, described anti-impact liner is ripple struction.
Stiffening rib is for strengthening the intensity of elbow body, coordinates anti-impact liner to improve the impact resistance of elbow body, and as preferably, described stiffening rib is curved, extends along the radian of described elbow body outer wall.
More preferably, the length of described stiffening rib is consistent with the curved portion of elbow body.
Described stiffening rib can be set to one, also can be set to some mutually arranged side by side, and therefore, in the utility model, described stiffening rib is at least one.
The two ends band of described elbow body is useful on the bellmouth of connecting tube material.
Compared with existing high layer sewerage system longspan elbow, the utlity model has following beneficial effect:
Existing longspan elbow structure, is subject to the impact of current and foreign matter in standpipe, the phenomenon that there will be breaks leaks for a long time.Particularly tall building (33m～100m), common large radian elbow structure cannot bear this impact force completely.
The utility model anti-impact longspan elbow, because being furnished with anti-impact liner and stiffening rib, can slow down the impact force that current and foreign matter fall, and can increase the intensity of pipe fitting body, effectively avoids breaking of pipe fitting body.
