Water hammer type vacuum negative pressure collecting well

Abstract

The invention relates to a water hammer type vacuum negative pressure collecting well. The water hammer type vacuum negative pressure collecting well comprises a collecting well base, a well body, a well base, a water hammer negative pressure structure, a well lid and a multi-layer filter cylinder, wherein the water hammer negative pressure structure comprises a power pipeline, a pump body, a water pressing valve, an air chamber, a water outlet pipe, a negative pressure gas chamber, a drainage valve and a magnetic gap spring, a flow guide slope is arranged at the bottom of the well body, the lowest end of a flow guide slope is connected with a power pipeline, the left side of the power pipeline is fixedly connected with the pump body, the pump body communicates with the negative pressure gas chamber and the air chamber, and the water pressing valve is arranged between the pump body and the negative pressure gas chamber. According to the water hammer type vacuum negative pressure collecting well, the water hammer negative pressure structure is arranged, under the interaction of the power pipeline, the pump body, the water pressing valve, the air chamber, the water outlet pipe, the drainage valve and the magnetic gap spring, when the water pressure in the air chamber is increased to be larger than the pressure in the pump body, water flows out of the water outlet pipe, and the working efficiency of sewage pumping is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewage collection equipment, in particular to a water hammer type vacuum negative pressure collection well. Background technique [0002] At present, sewage wells are used for sewage discharge and sewage discharge. They play a role in removing domestic sewage and rainwater. The pressure pump pumps out the sewage from the well body, and then discharges the sewage to other places through the pressure pump. [0003] However, the existing sewage collection wells usually extract sewage by manually controlling the pressure pump, which is cumbersome to operate, wastes time, and greatly reduces work efficiency. Although the structure is simple and the installation is convenient, it is not conducive to the later cleaning of debris, so it is not applicable Due to the current status of sewage collection, a water hammer vacuum negative pressure collection well is proposed, and the current sewage well cannot be used ...
