Pipe accessing device

Abstract

The invention provides a pipe accessing device. The pipe accessing device comprises a stand pipe connecting pipe, a water seal tank and a water seal partition hanger plate arranged in the water seal tank, wherein the top and two sides of the water seal partition hanger plate are respectively in sealing connection with the inner side of the wall of the water seal tank, the stand pipe connecting pipe penetrates through the water seal tank and is provided with a water outlet which is positioned in the water seal tank, a water inlet is arranged on the wall of the water seal tank, the water outlet and the water inlet are respectively arranged at the two sides of the water seal partition hanger plate, and the lowest position of the water outlet is not lower than the bottom end of the water seal partition hanger plate. The device has the advantages of being scientific in design, reliable in properties and capable of preventing odor return of the water seal.

Description

technical field [0001] The invention relates to a building water supply and drainage device, in particular to a pipe access device. Background technique [0002] At present, there are many problems in the drainage system, such as leakage, odor return, noise, etc., especially the pollution of leakage and odor return is particularly prominent; in order to solve the above problems, many technicians have proposed different solutions for the above problems: 1. In the special single standpipe system, a hollow water flow is formed by setting a water channel at the junction of the horizontal pipe and the standpipe, so as to improve the ventilation capacity of the drainage standpipe and reduce the odor return of the floor drain; 2. Adopt the double standpipe method and set a special Ventilation pipe to reduce the problem of floor drain odor return; 3. Adopt double standpipe self-circulation mode to improve the exhaust capacity of the standpipe and reduce the problem of floor drain od...

[0002] At present, there are many problems in the drainage system, such as leakage, odor return, noise, etc., especially the pollution of leakage and odor return is particularly prominent; in order to solve the above problems, many technicians have proposed different solutions for the above problems: 1. In the special single standpipe system, a hollow water flow is formed by setting a water channel at the junction of the horizontal pipe and the standpipe, so as to improve the ventilation capacity of the drainage standpipe and reduce the odor return of the floor drain; 2. Adopt the double standpipe method and set a special Ventilation pipe to reduce the problem of floor drain odor return; 3. Adopt double standpipe self-circulation mode to improve the exhaust capacity of the standpipe and reduce the problem of floor drain odor return; 4. In the special long joint single standpipe system, because the standpipe is partially enlarged, the The interior decoration has a certain impact and occupies indoor space; the above technologies have solved the floor drain problem to varying degrees, but they are not ideal. In use, there is still the problem of water seal pollution
