Problems solved by technology
[0002] In recent years, heavy rains have occurred from time to time. When the rainfall exceeds the drainage capacity of the pipeline, flood disasters will occur in the city; due to the aging facilities and small pipe diameter, the urban pipeline will be overloaded; the daily processing capacity of the sewage treatment plant is limited, If the regulation of the flow into the sewage treatment plant is not enough, it will increase the load of the treatment plant, reduce the treatment quality, etc.

The invention relates to a universal type rotational flow and constant flow device, and belongs to the technical field of water treatment equipment. The universal type rotational flow and constant flow device comprises a rotational flow and constant flow body, and the rotational flow and constant flow body comprises a rotational flow part and a flow guide part communicated with the rotational flow part. The rotational flow part is of a closed cylindrical structure formed by two round blocking faces and a columnar face. The flow guide part is tubular, is connected to the bottom of the columnar face of the rotational flow part and is tangent to the rotational flow part. A water inlet is formed in the bottom end of the flow guide part, and a water outlet is formed in one round blocking face of the rotational flow part along the center. The water outlet is connected with one end of a connecting pipe, the other end of the connecting pipe is connected with a fixing device, and a lifting device is arranged on the fixing device. The device can automatically limit flow passing through a downstream pipeline immediately when the flow is too large, and can hold up greasy dirt and flotage, and pollution and pipeline blocking are avoided.
Description
technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to a universal swirl constant flow device. Background technique [0002] In recent years, rainstorms have occurred from time to time. When the rainfall exceeds the drainage capacity of the pipeline, flood disasters will occur in the city; due to aging facilities and small pipe diameters, urban pipelines will be overloaded; the daily processing capacity of the sewage treatment plant is limited, If the control of the flow into the sewage treatment plant is not enough, the load of the treatment plant will be increased, the treatment quality will be reduced, and so on. In these cases, the traffic needs to be limited. Contents of the invention [0003] The object of the present invention is to provide a universal swirling constant current device for the defects of the prior art. [0004] The technical solution adopted by the present invention is: compris...
