The water collector end opening carries out side and bottom surface double seal by hush panel, and the seal isolation performance is strengthened, and seal is stable and reliable for performance, has improved reliability of products.
Described floor drain, the balance pivot of its weight control is located at the bottom of water collector, makes that the breakdown action of hush panel is sensitiveer, more flexible, has guaranteed the performance of product.
Described floor drain, its cover plate and water collector are fixed on the tube head, and the upper end outer rim of tube head is provided with boss, and floor drain and tube head constitute one, and be easy to use; In order to strengthen sealing, set up seals such as sealing ring at water collector and tube head contact position.
The utility model is tubular applicable to various cross sections, and as round tube, rib pipe etc., material is feasible various materials, as engineering plastics etc.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1, a structural representation of the present utility model also are an embodiment.
The vertical view of Fig. 2, Fig. 1.
Among the figure: 1 cover plate, 2 sealing rings, 3 water collectors, 4 tube heads, 5 balance pivots, 6 weights, 7 hush panel, 8 hush panel boss.
As shown in the figure, the utility model Backflow-proof floor drain, cover plate 1 has water collector 3, the end opening of water collector 3 is combined with the hush panel 7 by weight 6 controls, hush panel 7 is provided with boss 8, the side face of boss 8 is sealed and matched with the medial surface of water collector 3 end openings and contacts, the end face of water collector 3 end openings is sealed and matched with hush panel 7 plate faces and contacts, balance pivot is located at the bottom of water collector 3, cover plate 1 and water collector 3 are fixed on the tube head 4, the upper end outer rim of tube head 4 is provided with boss, and water collector 3 is provided with sealing ring 2 with tube head 4 contact positions.
Under the normal condition, hush panel 7 is sealed water collector 3 end openings, the pipe in top isolation, stoped foul smell on return.When drowning, the weight of water is opened hush panel 7 in the water collector 3, and water falls, and this hush panel also has the sewage of prevention and returns excessive effect.
