Dual mechanical seal floor drain core

Abstract

A dual mechanical seal floor drain core is composed of an upper floor drain core body, a floater, a lower floor drain core body and a valve. The floater is mounted in the upper floor drain core body, the lower end of the floater is matched with the water outlet of the upper floor drain core body, and the lower end of the floater seals the water outlet of the upper floor drain core body through gravity or magnetic force; the lower floor drain core body is connected with the lower end of the upper floor drain core body, the valve is mounted on the water outlet of the lower floor drain core body to seal the water outlet of the lower floor drain core body through gravity or magnetic force. The open-close of the dual mechanical seal floor drain core is realized through the changes of water flow entering the floor drain core. The dual mechanical seal floor drain core has the advantages of rapid opening and closing, small passing resistance of water flow, good sealing effect and uneasy blockage, also can prevent the positive and negative pressure in the sewer from damaging the sealing performance of the floor drain core and has good anti-overflow performance.

Description

technical field [0001] The invention relates to a floor drain core, in particular to a double mechanical seal floor drain core. 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 core is not enough, most of which are only 10? The drainage capacity of the floor drain is weak, and it is prone to poor drainage; ③The self-cleaning ability of the floor drain core is poor, and it is easy to catch hair, deposit sludge, and form a blockage; ④The structure of the floor drain core is unreasonable, and the water seal retention ability is poor...
