Technical Field

The utility model relates to a plumbing technical field especially relates to a hydrocone type waste water drainage riser built-in fitting from taking water seal.

Background

The drainage of the same layer is widely applied at present. The same-layer drainage means that the whole floor of the toilet descends by 300-500mm to form a caisson, the drainage branch pipes of the floors do not penetrate through the floor, and the drainage branch pipes are connected to a main drainage pipe in the caisson. If the condition that needs clearance mediation takes place, carry out the drainage mode of maintenance in this layer of caisson. The installation mode of the device is filled and buried and is overhead. The same-layer drainage water falling plate area needs to cover all the waste water drainage points and the connected drainage branch pipes, and the requirements on the gravity drainage gradient and the water seal height of a trap are mainly met. The washbasin, the shower (basin) and the washing machine can basically drain water above the floor of a toilet due to the fact that the water outlet is higher, but a floor drain needs to collect water accumulated on the floor, the water outlet of the floor drain needs to be flat or lower than the floor, and a water seal needs to be arranged to prevent odor from flowing backwards. Two types of techniques, lower drainage and same-floor drainage, have emerged. In addition, in the existing same-floor drainage mode, the caisson is integrally backfilled or a floor slab is supported in an overhead layer mode after the waterproof and drainage pipelines are laid. And the S, P type water seal is generally adopted at present, so that the deodorization problem can be relatively reliably solved. Regardless of the maintenance space, the water seal occupies a space of approximately 50x150x200mm.

However, the existing same-layer drainage technology generally has the following problems: (1) And the plate lowering method is adopted for drainage on the same layer, the plate lowering area inevitably influences the layer height, the plate lowering construction is complex, the cost is high, and secondary drainage needs to be set for preventing the volume water in the caisson. (2) The most difficult problem in wastewater drainage is floor drain drainage, a drainage inlet of a floor needs to be leveled or lower than the floor, and a S, P type water seal is usually adopted to prevent the drainage vertical pipe from stinking, so that the linear trap needs to be lower than the floor, needs to penetrate a floor slab or be provided with a caisson, has a complex structure, is easy to block and is difficult to overhaul. (3) On the caisson, no matter the caisson is integrally backfilled or the floor is supported in an overhead layer mode, the waterproof layer and the drainage pipeline in the caisson are difficult to inspect and maintain, and if a problem exists, civil engineering operation is needed, the adjacent disturbance and the pollution are great. (4) The toilet floor drain is provided with a water seal, wherein the water evaporation of the floor drain in a dry area can lose the deodorization function after a long time. (5) The bent pipes/P-shaped bends/S-shaped bends with various angles in the caisson are connected with the straight pipes, so that the construction is complex, the hidden danger of water leakage is high, and the landfill treatment is not easy to inspect and maintain.

In addition, according to GB50015-2019 'design Standard for Water supply and drainage for buildings' 4.3.13, a water seal cannot be repeatedly arranged on a drainage pipe section of a sanitary ware. This is because the double water seals form air lock, which causes air lock, poor drainage and drainage noise. If the water seal is arranged on the drainage pipe section of the sanitary ware and the water seal is additionally arranged on the drainage pipe, bubble breaking noise is generated when the sanitary ware drains water, and phenomena such as bubbling, overflow, water seal damage and the like are generated on the sanitary ware at the bottom layer. The three-way water seal pipe 20 is combined with the tank type water seal 12 of the channel, so that the defects are overcome.
