A sewage collection and automatic discharge well

Abstract

The invention discloses a sewage collection and automatic discharge well which comprises a gravity collection pipe, a well body, a sewage discharge pipe, a vacuum valve and a vacuum pipe. The vacuum valve comprises a work cavity, a pilot valve communicated with the work cavity, a medium inlet in butt joint with the sewage discharge pipe and a medium outlet connected with the vacuum pipe. The vacuum pipe is further provided with an air taking opening; the pilot valve is provided with a vacuum connector in butt joint with the air taking opening, an atmosphere connector communicated with the atmosphere and a pressure connector for sensing the liquid level in a well body; the pressure connector is further provided with a sensitive element downwards extending to the well body. According to the sewage collection and automatic discharge well, the opening and closing power of the vacuum valve comes from a vacuum system, opening and closing can be achieved without adding extra power equipment, the power loss of the system is lowered, safety is higher, meanwhile the sewage collection and automatic discharge well has the advantages of automatic collection, quantitative discharge and being free of manual guard, and the sewage collection and automatic discharge well is simple in structure and convenient and practical.

Description

technical field [0001] The invention belongs to the field of vacuum drainage, in particular to a sewage collection and automatic discharge well for the transition between gravity flow and vacuum flow. Background technique [0002] At present, the outdoor drainage system mainly adopts the gravity system. The sewage at the user end flows from the high place to the low place under the action of the earth's gravity through the gravity pipeline laid down along the road. The gravity drainage system has the advantages of simple construction and low operation and maintenance costs, but its disadvantages are also very obvious, that is, it is restricted by the terrain, the excavation volume is large, and the ground is destructive. Siphon, resulting in difficult construction and high construction costs. [0003] In recent years, the use of vacuum to collect and treat domestic sewage has gradually entered people's field of vision. The laying of vacuum pipes does not require slopes, has...

Problems solved by technology

However, in order to realize the actions of the above-mentioned controller, it is necessary to add additional power equipment, such as compressed air source or power supply, which directly increases the work intensity when laying out pipelines

Especially for some remote mountainous areas with weak infrastructure, the construction is often affected due to the lack of power facilities

[0004] In addition, in order to maintain the safety of the system, it is also necessary to carry out regular inspection and maintenance on the controller. During the inspection and maintenance process, the drainage system cannot work, which will also affect people's normal life.
