Abstract
This utility model relates to an anti-impact 90-degree reducing elbow which is used for a PVC pipe system of discharging sewage and rainwater indoors and outdoors. At present, the connection of the bottom of discharging vertical pipe and lateral pipe usually adopts a diameter-changing piece and two 45-degree elbows, the connection is inconvenient, the joint is loosened easily, and the inside wall at the back of elbow which is at the bottom of discharging vertical pipe is easily broken by hard objects from high position of vertical pipe. This utility model includes the 90-degree reducing elbow, and the end of elbow is provided with a large pipe socket and a small pipe socket which is integrated through injection molding, the inside wall at the back of elbow is closely lined with an arc-shaped anti-compaction plate. The installation of this utility model is convenient, the joint with discharging vertical pipe and lateral pipe is stable and reliable; the anti-compaction capability of inside wall at the back of elbow is enhanced.
Description
Technical field
The utility model relates to the elbow fittings that the pvc pipe road system of indoor and outdoor sewage, storm-water drainage uses, especially a kind of anti-impact 90 degree reducing elbows.
Background technique
In the pvc pipe road system of existing indoor and outdoor sewage, storm-water drainage, its discharging riser bottom and normal 45 ° of structures that elbow assembles that adopt a reducing element (D160mm*110mm) and two D160mm of being connected of transverse tube.There is following shortcoming in this kind linkage structure: 1, accessory is many, connects inconvenient; 2, being positioned at the hard foreign material that the elbow back inwall at discharging riser bottom place fallen from the standpipe eminence easily breaks; 3, because elbow is not fixed, and it is relatively poor that the ability of water flow impact pressure is born in the joint, after long-time the use, the joint is easily pulled.
The model utility content
The purpose of this utility model is to provide a kind of anti-impact 90 degree reducing elbows of integral type, makes things convenient for it and discharges being connected of standpipe, transverse tube, improves the reliability of joint, and the hard foreign material of avoiding the reducing elbow inwall to be fallen from the standpipe eminence are broken.
For this reason, the utility model adopts following technological scheme: anti-impact 90 degree reducing elbows, comprise 90 degree reducing elbow bodies, it is characterized in that the end of curved head body has and big bellmouth of its injection moulding all-in-one-piece and little bellmouth, the tight lining of the inwall at curved head body back one arc anti-impact plate.The utility model is an integral structure, and the little bellmouth (bore is generally D110mm) of an end is convenient to directly link to each other with the discharging standpipe of D110mm; The big bellmouth (bore is generally D160mm) of the other end is convenient to directly link to each other with the transverse tube of D160mm.The utility model is easy for installation, and makes its joint with discharging standpipe, transverse tube reliable and stable.Because the water and the impurity that flow down from standpipe directly impact on the arc anti-impact plate, the hard foreign material of having avoided the reducing elbow inwall to be fallen from the standpipe eminence are broken, and have improved the impact resistance of curved head body back inwall.
As further technological scheme, the outer wall at curved head body back connects one and is used for the bearing that curved head body is located.The curved head body back is connected with bearing, and this bearing both can adopt bolt with metope, also can adopt bolt with the level ground, thereby curved head body is positioned.Bearing is a PVC integral molded plastic spare, single injection-molded, with curved head body be split production, bearing and curved head body are bonding with PVC glue.
As further technological scheme, curved head body be shaped as slick and sly excessive big radian shape.Curved head body adopts big radian rounding off, to improve the current performance.
Integral structure of the present utility model has following beneficial effect: easy for installation, its joint with discharging standpipe, transverse tube is reliable and stable; Improve the impact resistance of curved head body back inwall, prolonged the working life of elbow; Effectively located curved head body by bearing.
Below in conjunction with Figure of description and embodiment the utility model is further described.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is a stereogram of the present utility model.
Embodiment
Anti-impact 90 degree reducing elbows shown in Fig. 1-2 are a reducing great circle arcuation curved head body 1, and its two-port forms the big bellmouth 2 of little bellmouth 3, D160mm of D110mm respectively, can be connected with D110mm standpipe, D160mm transverse tube socket joint respectively.The inwall at curved head body 1 back closely posts a thin-wall stainless steel arc anti-impact plate 4, and to improve the impact strength of curved head body back inwall, curved head body back outer wall and bearing 5 usefulness PVC glue are bonding.
Add man-hour, a thin-wall stainless steel arc anti-impact plate processes in advance, then it is positioned in the injection moulding die cavity, and behind the location, with the curved head body integrated injection molding, curved head body back outer wall is bonding with PVC glue with the bearing that processes in advance, makes up in aggregates.
Claims (3)
1, anti-impact 90 degree reducing elbows comprise 90 degree reducing elbow bodies (1), it is characterized in that the end of curved head body (1) has and big bellmouth of its injection moulding all-in-one-piece (2) and little bellmouth (3), the tight lining of the inwall at curved head body (1) back one arc anti-impact plate (4).
