Abstract

The utility model relates to a sanitary fixture, particularly an anti-overflow backwater floor drain. The utility model mainly achieves the purposes of simple structure and convenient use of the anti-overflow backwater floor drain. The utility model is characterized in that the upper end of a conduit is provide with a flanging, and the upper opening of a water return chamber is also provided with a flanging. A pad is arranged between the upper end of the conduit and the upper opening of the water return chamber, and the upper part of the water return chamber is provided with a water outlet hole. A reversing valve in the water return chamber is an object in the shape of a reverse cup cover, and the specific gravity of the reversing valve is less than 1. The conduit, the reversing valve and the water return chamber are arranged in a casing.

Description

A kind of counnter attack backwater floor drain that overflows

The utility model relates to a kind of sanitary installation, particularly relates to the excessive backwater floor drain of a kind of counnter attack.

Chinese patent has been opened the excessive backwater floor drain (patent No.: 90202612.7) of a kind of novel counnter attack, it is made up of hitch, the reversing valve of block material web plate, bucket, conduit, multi-arm and the chamber of turning one's coat, but its conduit is connected with the chamber of turning one's coat with the hitch of multi-arm by screw thread, and more complicated is used trouble.

The purpose of this utility model provides the excessive backwater floor drain of a kind of counnter attack simple in structure, easy to use.

The utility model is made up of block material web plate, housing, conduit, reversing valve and the chamber of turning one's coat, it is characterized in that: the upper end of conduit has flanging, chamber suitable for reading of turning one's coat also has flanging, suitable for reading of the upper end of conduit and the chamber of turning one's coat has a pad, top in the chamber of turning one's coat has weep hole, the reversing valve in the chamber of turning one's coat is proportion and is inverted the shape object less than 1 bowl cover, and conduit, reversing valve and the chamber of turning one's coat are contained in the housing.

Because screw thread is not established in the utility model conduit and the chamber of turning one's coat, the chamber of turning one's coat is an integral body, does not establish the hitch of multi-arm, only has weep hole on the top in the chamber of turning one's coat, so assembling and dismounting are easily, structure is also very simple, easy to use.

Below in conjunction with accompanying drawing the utility model is elaborated,

Fig. 1 is structural representation than Cui embodiment of the utility model,

Fig. 2 is another structural representation than Cui embodiment of the utility model,

Fig. 3 is another structural representation than Cui embodiment of the utility model,

With reference to Fig. 1, Fig. 2,1 expression block material web plate among the figure, the upper end of conduit 2 has flanging, chamber 6 suitable for reading of turning one's coat also has flanging, suitable for reading of the upper end of conduit and the chamber of turning one's coat has a pad 4, top in the chamber of turning one's coat has weep hole, the reversing valve 3 in the chamber of turning one's coat is proportion and is inverted the shape object less than 1 bowl cover, or employing proportion is less than 1 plectane, excessive in order to prevent anti-water impact of overflowing, make conduit and the reversing valve jack-up that makes progress, on the inside wall in chamber of turning one's coat, have groove, in flanging end, conduit upper end tool plush copper 7, the plush copper of flanging end, conduit upper end is entrenched in the groove on the chamber inside wall of turning one's coat, conduit, the reversing valve and the chamber of turning one's coat are contained in the housing 5.

With reference to Fig. 3, the upper end of conduit 7 has flanging, and the lower end of conduit 7 also has flanging, and the reversing valve 8 employing proportions in the chamber of turning one's coat are conical object less than 1 upper surface.
