Access apparatus of pipeline for anti-back overflow

Abstract

The invention provides an access apparatus of a pipeline for anti-back overflow. The apparatus which comprises a vertical tube connecting tube, a water seal tank, and a water seal and division hanger plate arranged in the water seal tank is characterized in that: the top of the water seal and division hanger plate is hinged to the inner side of the top tank wall of the water seal tank, the vertical tube connecting tube which is inserted through the water seal tank is provided with a water outlet, and a lowest part of the water outlet is not lower than the bottom of the water seal and division hanger plate; the bottom of the water seal and division hanger plate bears against the wall of the water seal tank, and the water seal and division hanger plate divides the water seal tank into two tanks which are not communicated; and the water outlet is arranged in one of the two tanks, and the wall of the other one of the two tanks is provided with a water inlet. The apparatus of the present invention has the advantages of scientific design, reliable performance, and self seal for anti-back overflow.

Description

technical field [0001] The invention relates to a building water supply and drainage device, in particular to an anti-backflow pipe access device. Background technique [0002] At present, there are many problems in the drainage system, such as leakage, back odor, noise, etc., especially the problems of leakage, pipe blockage, sewage overflowing into the room, and back odor pollution. In order to solve the above problems, many technicians have focused on the above problems Different solutions are proposed: 1. In the special single riser 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 Double standpipe method, set up 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 sta...

[0002] At present, there are many problems in the drainage system, such as leakage, back odor, noise, etc., especially the problems of leakage, pipe blockage, sewage overflowing into the room, and back odor pollution. In order to solve the above problems, many technicians have focused on the above problems Different solutions are proposed: 1.

Adopt Double standpipe method, set up 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 riser pipe is partially expanded, it has a certain impact on interior decoration and occupies indoor space; the above technologies have solved the problem of floor drains to varying degrees, but none of them can solve the problem of blocked sewage overflow
