Detailed Description

To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments, structural features and effects of the present invention will be made with reference to the accompanying drawings and examples.

The design concept of the invention is based on the same layer drainage concept; on the basis of the same-floor drainage concept, the cyclone drainage principle and the Sovitto drainage principle are combined, and the purpose of designing a same-floor drainage system applicable to any building is achieved.

The quality of the drainage fittings is generally judged by adopting the following principles:

standardization principle: all fittings entering the drainage field, such as connection modes, connector sizes, wall thicknesses, materials and the like, must meet relevant national standards and must meet standardized design principles.

The normalization principle is as follows: all the fittings entering the drainage field have to meet the national relevant standards in terms of drainage principle, drainage capacity, technical requirements and the like, and meet the standardized design principle;

specifically, the drainage capacity depends on ensuring the pressure balance in the drainage pipe to the maximum extent on the premise of not damaging the water seal, the basic technical requirement of drainage in China is based on 50mm water seal, 80% of the 50mm water seal is taken as a test reference, and whether the pressure fluctuation in the drainage pipe is within 50x10x0.8=400Pa is taken as a reference to judge whether the drainage pipe is qualified or not when the drainage pipe drains water;

generally, pipeline lines and the like are laid in the cushion layer 2, and the standard of the cushion layer 2 of a common floor is not less than 60mm, but the height of the toilet is generally lower than that of other indoor areas, namely the cushion layer of the toilet is not thicker than that of the cushion layer of other indoor areas, so that the requirement of 50mm water sealing of the transverse branch pipe in the cushion layer 2 of the toilet cannot be met under the condition of certain indoor height, and the problem of water sealing of the transverse branch pipe in the same-floor drainage system is solved due to the limit.

Further, methods for generally ensuring pressure balance include:

a. in a limited space, the air circulation area in the pipe is increased as much as possible, and the thickness of a film formed on the pipe wall by water is reduced.

b. In a limited space, the influence of transverse water flow on air circulation in the vertical pipe is reduced as much as possible, and the descending water flow direction and the form of the special drainage accessory-Suvittor are changed in advance;

c. in a limited space, the descending speed of water flow is reduced, the air circulation area in the pipe is increased, and the fluctuation of air pressure in the pipe can be reduced to the greatest extent, such as increasing the roughness of the inner wall of the pipe, locally changing the descending direction of the water flow, participating in measures of the rotation angle of the water flow and the like;

d. the practical principle is as follows: all fittings entering the drainage field must meet the requirements of popularization, and can be applied to any project by anyone and improve the application value of the whole project.

The invention aims to realize same-layer drainage on the premise of ensuring water sealing and drainage capacity.
