Double-layer sealing floor drain device

Abstract

A double-layer sealed floor drain device is composed of a top cover plate, an upper part of a main body, a float, a lower part of the main body and an adjustable door. The float is installed in the upper part of the main part, and the lower end of the float is matched with the water outlet of the upper part of the main part, and the lower end of the float is sealed to the water outlet of the upper part of the main part by gravity or magnetic force; the lower part of the main part is connected to the lower end of the upper part of the main part, The adjustable door is installed at the water outlet at the lower part of the main body, and the water outlet at the lower part of the main body is sealed by gravity or magnetic force. Through the change of the water flow entering the floor drain, the opening and closing of the double mechanical seal floor drain is realized. The double mechanical seal floor drain has the advantages of fast switching, small resistance when water flows through, good sealing effect, and is not easy to be blocked, and can prevent the positive and negative pressure in the sewer from damaging the sealing performance of the floor drain, and has good anti-backflow performance.

Description

technical field [0001] The invention relates to a floor drain, in particular to a double-layer sealed floor drain device. 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; ③ the self-cleaning ability of the floor drain is poor, and it is easy to catch hair, deposit sludge, and form a bloc...
