Problems solved by technology

[0003] The water seal depth of the trap is affected by many factors such as self-siphon, induced siphon, and natural evaporation. The water seal will gradually lose. If the water seal is not replenished frequently, the anti-odor effect will not be achieved.
In addition, there are easy gaps between the existing ordinary water trap and the ground connection, causing odor and flying insects to enter the room, and the odor return effect cannot be achieved well
[0004] This shows that above-mentioned existing water trap obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

Embodiment Construction

[0027] The invention provides a double-seal water trap, which includes a water seal part and a mechanical seal part, and the mechanical seal part is installed at the upper end of the water seal part. At present, the common water traps on the market only use water seals to prevent the odor in the drainage pipes from entering the room, and the materials are mostly soft pipes. While increasing the sealing depth, the mechanical sealing part is added, which can greatly reduce the loss of water seal due to natural evaporation and induced rainbow attraction. At the same time, if the washbasin has been idle for a long time and the water trap is insufficient, resulting in the disappearance of the water seal, the mechanical seal can be used as the second protection of the trap to achieve the anti-odor effect.

Abstract

The invention discloses a double-sealing trap, which comprises a water sealing part, and also comprises a mechanical sealing part, wherein the mechanical sealing part is mounted at a position of the upper end of the water sealing part; the water sealing part comprises a trap main body; a water outlet end of the trap main body is also connected with two stages of reversing elbows; a telescopic locking structure is arranged between the two stages of reversing elbows. The double-sealing trap provided by the invention can be used for solving the problems that a trap is poor in water-sealing retention ability and poor in sealing in an existing building water supply and drainage technique, and is good in stench return prevention effect, simple in structure, convenient to mount and suitable to popularize and apply.

Description

technical field [0001] The invention relates to a building drainage device, in particular to a double-seal water trap. Background technique [0002] The building drainage system is the channel connecting the outdoor sewage drainage pipes and the indoor environment. The hidden pollution of the indoor environment caused by the drainage system has been ignored. The gaseous pollutants contained in the odor in the drainage system can cause diseases such as reduced blood oxygen carrying capacity, lung collapse and injury; while the non-gaseous pollutants contained in the drainage system, such as viruses and bacteria, can cause diseases such as diseases such as diarrhea. When the water trap cannot effectively block the odor in the drainage pipe, the phenomenon of "returning odor" will occur, causing pollution to the indoor environment and posing a threat to the health of residents. As one of the links to ensure that the indoor air is not polluted by pathogenic bacteria in the dra...
