Slow-closing type airtight water drainage system

Abstract

The invention discloses a slow-closing type airtight water drainage system and belongs to the technical field of water drainage systems. The slow-closing type airtight water drainage system comprisesa compressor, a pressure exchange device, a drainage pipe and a sewage storage container. The compressor, the drainage pipe and the pressure exchange device are in fit connection. One end of the drainage pipe is in fit connection with the sewage storage container, and the other end of the drainage pipe is connected with a gravity pipeline of the sewage drainage system. According to the slow-closing type airtight water drainage system, delay of opening and closing is achieved, so that thorough sewage drainage is guaranteed; by using the small pipe for sewage drainage, the occupied space is small, the appearance is attractive, the flux is large, and the airtightness is good; and the water drainage distance is 10-50 m, so that the slow-closing type airtight water drainage system is suitable for long distance water drainage such as bathrooms and water drainage pipes and also suitable for dispersion type centralized drainage places such as cruises and subways.

Description

technical field [0001] The invention belongs to the technical field of drainage systems, in particular to a slow-closing airtight drainage system. Background technique [0002] In the existing residential quarters, the drainage of toilets, kitchens, etc. is directly discharged to the gravity pipe. If a drainage point needs to be rebuilt at a place far away from the gravity pipe, the sewage discharge from the drain pipe to the gravity pipe is generally realized by a lift pump, but the general type of pump is Relatively large, the large pump body has high cost and high noise, while the small pump body has poor passability and is easy to block. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the purpose of the present invention is to design and provide a technical scheme of a slow-closing airtight drainage system, which has time-delay in opening and closing, ensures thorough sewage discharge, uses small pipes to discharge s...
