Mechanical sealing and water sealing combined floor drain

Abstract

A mechanical seal and water seal combined floor drain consists of a floor drain cover, a main floor drain body, a float and a hose type magnetic seal valve. The float is arranged inside the main floor drain body, the lower end of the float is matched with a water outlet of the main floor drain body, the water outlet of the main floor drain body is sealed with the lower end of the float by gravity or magnetic force; and the hose type magnetic seal valve is arranged at the water outlet of the main floor drain body, and the water outlet is sealed by the magnetic force. Opening and closing of the mechanical seal and water seal combined floor drain are realized by the change of water flow entering the floor drain. The mechanical seal and water seal combined floor drain has the advantages of quick opening and closing, small resistance when water passes through, good sealing effect, uneasy blockage and the like, can prevent positive and negative pressure in a sewer from damaging the sealing performance of the floor drain, and also has good overflow resistance performance.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain combined with a mechanical seal and a water seal. Background technique [0002] As an important device to remove ground water, the floor drain plays an important role in building drainage. The floor drain should have two basic functions: one is smooth drainage, which can quickly remove the accumulated water on the ground; the other is good sealing, which can effectively prevent the odor in the sewer pipe from entering the room. The common problems of existing floor drains are mainly manifested in: ①The height of the water seal of the floor drain is not enough, most of them are only 10-30mm, and it is easy to dry up, causing the floor drain to lose its sealing effect, and the odor in the drainage pipe enters the room; ②The drainage capacity of the floor drain Weak, prone to poor drainage; ③The self-cleaning ability of the floor drain is poor, and it is easy to catch hair, deposit sl...
