Pipeline connection device for preventing overflow return and sludge

Abstract

The invention provides a pipeline connection device for preventing overflow return and sludge. The device comprises a riser connecting pipe, a water sealing tank and a water sealing and dividing hanging plate, wherein the top end of the water sealing and dividing hanging plate is hinged with the inner side of the tank wall at the top of the water sealing tank; the riser connecting pipe penetrates through the water sealing tank and is provided with a draining port; when the bottom end of the water sealing and dividing hanging plate supports against the tank wall of the water sealing tank, the water sealing tank is divided into two tank bodies which are not mutually communicated by using the water sealing and dividing hanging plate; the draining port is arranged in one tank body; a water feeding port is arranged on the tank wall of the other tank body; a tank body separating board is arranged at the bottom of the water sealing tank and is positioned between the riser connecting pipe and the water sealing and dividing hanging plate; the top of the tank body separating board is lower than the tank wall at the top of the water sealing tank and is not lower than the bottom end of the water sealing and dividing hanging plate; and the lowest part of the draining port is level with the bottom of the water sealing tank. The device has the advantages of scientific design, reliable performance and capabilities of automatically sealing and preventing overflow return and sludge.

Description

technical field

[0001] The invention relates to a building water supply and drainage device, in particular to an anti-backflow and anti-silt pipeline connection 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 exhau...
