Preferably, the flange comprises a boss and a flange surface, and the boss is connected with the mirror surface through the flange surface.
Preferably, the upper surface of the boss is provided with a boss water chute.
Preferably, the number of the boss water guide grooves is four.
Preferably, the boss water guide groove has a slope with a high inner part and a low outer part.
Preferably, the upper surface of the flange surface is provided with a flange surface drainage groove.
Preferably, the area of the flange surface drainage groove is larger than that of the boss; the width of the flange surface drainage groove gradually narrows from inside to outside; the flange face drainage groove has a slope with a high inside and a low outside.
Preferably, the upper surface of the mirror surface is provided with a mirror surface drainage groove.
Preferably, the area of the mirror drainage groove is larger than that of the flange surface; the mirror surface drainage groove has a slope with a high inside and a low outside.
Preferably, the central hole of the boss is provided with a removable seal to prevent water from flowing into the cavity.
Compared with the prior art, the utility model has the advantages of it is following:
1. the adapter flange and the end cover are designed into a whole, so that concentricity deviation in the installation process is avoided; meanwhile, the number of parts in the assembling process is reduced, the production efficiency is improved, and the production cost is reduced.
2. The water guide groove is additionally arranged at the position of the boss and the mirror surface which are easy to accumulate water, so that water can be timely led out through the water guide groove and can be timely discharged through the flange surface and the mirror surface, and the risk of equipment failure is reduced.
