Problems solved by technology

[0002] Floor drains are the most problem-prone terminal fittings in the drainage system of indoor buildings. Common floor drain water seals use water seals, magnetic flaps, float seals, membrane seals, etc., but none of them can prevent the peculiar smell of residential pipes from escaping; Or the water seal fails because there is no water in the floor drain water seal, or the floor drain flap cannot be closed because the sewage entrains debris; or the water seal breaks away from the floor drain because of a sudden increase in water flow, causing dirty water to leak out

Abstract

The invention relates to a multilayer water seal device with a top cover. The device comprises at least two layers of water seals, a water seal box, and a top cover, wherein the two layers of the water seals form a sealed connection, and the water seal box is connected with a drain pipe. At least the upper layer water seal of the two water seals is a bell jar type water seal, the position of the bell jar type water seal is flushed with or higher than the position of the lower layer water seal, and the immersion depth of the bell jar type water seal is lower than the immersion depth of the lower layer water seal. The top cover is arranged above the upper layer water seal. The water seal box is provided with at least one layer of a ring groove, wherein the ring groove is around the outer part of the drain pipe, the ring groove is arranged into an inner layer ring groove and an outer layer ring groove, and the position of the outer layer ring groove is higher than the position of the inner layer ring groove. At least one layer of the bell jar type water seal is correspondingly placed on a layer of the ring groove corresponding to the position of the bell jar type water seal. With the technical scheme of the present invention, the blocking effect for prevention of water current impact can be provided, the overtopping and the tight shut caused by pressing can be prevented when exceeding the immersion depth; the process is simple, and is easy to perform, and is suitable for the mass production.

Description

technical field [0001] The invention relates to a water sealing device, in particular to a multi-layer water sealing device with a top cover. Background technique [0002] Floor drains are the most problem-prone terminal fittings in the drainage system of indoor buildings. Common floor drain water seals use water seals, magnetic flaps, float seals, membrane seals, etc., but none of them can prevent the peculiar smell of residential pipes from escaping; Or the water seal fails because there is no water in the floor drain water seal, or the floor drain flap cannot be closed because the sewage entrains debris; or the water seal breaks away from the floor drain because of a sudden increase in water flow, causing dirty water to leak out. Contents of the invention [0003] The object of the present invention is to provide a multi-layer water seal device with a top cover to prevent the water seal from being washed away by water, aiming at the deficiencies of the prior art.
