Anti-blocking self-suction type drainage valve element and related drainage equipment

Abstract

The invention discloses an anti-blocking self-suction type drainage valve element and related drainage equipment. The valve element comprises an upper shell (1) and a lower shell (2); the upper shell(1) is a cylinder with two open ends; an annular convex edge (11) is formed on the inner side wall of the upper shell in the circumferential direction; the lower shell (2) comprises a tray (22) located at the lower end and at least one cantilever (21) extending upwards from the side edge of the tray (22); the upper end of the cantilever (21) is connected with the upper shell (1), the tray (22) extends upwards to form a guide column (23), and the guide column (23) is sleeved with a sealing cover (3); repelling permanent magnets (41 and 42) are embedded into the sealing cover (3) and the guide column (23) respectively, and the repulsive force of the repelling permanent magnets can eject the sealing cover (3) upwards; the sealing cover (1) is in close contact with the convex edge (11) to sealthe drainage valve element. The valve element is rapid in water draining, not easy to block, smooth in sliding and easy to clean, and the magnets are convenient to replace.

Description

technical field [0001] The invention belongs to the technical field of drainage equipment, and in particular relates to a drainage valve core used for drainage equipment such as a sink of a pool and a floor drain. Background technique [0002] The drain spool is the main functional component of various drainage equipment. In order to prevent backwater, deodorize, and insects, etc., the drain valve core is usually required to have a self-sealing function, so that the drain port can be closed when there is no water. There are many kinds of self-enclosed drain valve cores in the prior art, and if they are divided according to their principles, they can generally be divided into elastic return type and magnetic suction type. Among them, the magnetic suction drain valve core is more and more popular because of its simple structure and durability. However, the current magnetic suction type drain valve core also has its obvious disadvantages. [0003] One disadvantage of the mag...
