Drain discharge vertical pipe structural slab pre-embedded double-eccentric water sealing pipe type stinking-proof ponding disposer

Abstract

Aiming at the problems that it is inconvenient to remove stagnant water in the fill layer, and it is easy to return odor and harmful gas from the septic tank, the present invention provides a double eccentric water-sealed tube type anti-odor stagnant water processor embedded in the structural plate of the sewage riser; the shell is Tubular structure with both upper and lower ends open. The large eccentric part is a tubular body with a crescent-shaped groove at the eccentric part. The cover plate of the large eccentric part is crescent-shaped. The matching cover is installed on the groove of the large eccentric part. The large eccentric part and the large eccentric part The cover plate of the large eccentric part cooperates to form a large eccentric water seal part, and the small eccentric part is matched and inserted in the large eccentric part. The cover plate of the small eccentric part cooperates to form a small eccentric water seal, the structure of the small eccentric water seal and the large eccentric water seal are the same, and the small eccentric water seal and the large eccentric water seal cooperate to form an annular water seal structure; the small eccentric A first socket is arranged in the part, and both the first socket and the second socket arranged in the lower port of the casing are used for inserting the standpipe.

Description

technical field [0001] The invention relates to a double-eccentric water-sealed tube type anti-odor pond water processor pre-embedded in a structure plate of a sewage riser, and belongs to the technical field of water drainage and anti-odor devices in filling layers. Background technique [0002] The drainage system in the modern construction industry, especially the drainage system in the toilet, the drainage system on the same floor, the geothermal system, the filling layer of at least 100mm to 200mm from the structural plate to the finished surface; the drainage of water appliances such as washbasins, showers, bathtubs, washing machines, etc. The pipes are set in the filling layer through the finished surface, so as time goes by, people step on it, the waterproof material is aging and other reasons, the place where the drainage pipe for installing water appliances passes through the finished surface, such as the joint of the floor tiles, will go to the filling layer Infil...
