Problems solved by technology

When the upward opening gate is used to control the flow, due to the long switching time, the response is not sensitive, and there is a certain lag
Secondly, the flow sensor requires the pipeline to be full pipe flow in application. If the pipe is not full pipe flow, the flow sensor cannot measure

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] The invention discloses a drainage pipe flow control method, which comprises a flow signal acquisition device and a control system; using the control system to set the required calibration flow value Q in the drainage pipe; using the flow signal acquisition device to collect the real-time flow value in the drainage pipe Q1 and feedback to the control system; by comparing the calibrated flow value Q and the real-time flow value Q1 to control the opening or closing of the down-opening gate in the drainage pipe; when the real-time flow value Q1 is greater than the calibrated flow value Q, the co...

Abstract

The invention discloses a drainage pipeline flow control method and device. The device comprises flow signal collecting equipment and a control system. A calibrated flow value Q needed inside a drainage pipeline is set by means of the control system; the flow signal collecting equipment is used for collecting a real-time flow value Q1 inside the drainage pipeline and feeds back the real-time flow value Q1 to the control system. The device is characterized in that a downward-opening type gate inside the drainage pipeline is controlled to be opened or closed by comparing the calibrated flow value Q and the real-time flow value Q1. The device is simple in structure, convenient to use, capable of accurately and efficiently measuring the flow inside the drainage pipeline, the flow inside the drainage pipeline is controlled in real time through the downward-opening type gate, and meanwhile a flow sensor can still accurately measure the flow on the condition that the pipeline is not filled.

Description

technical field [0001] The invention relates to a flow control method and device, belonging to the technical field of drainage pipeline flow control, in particular to a drainage pipeline flow control method and device. Background technique [0002] At present, the flow control equipment of the drainage pipeline all adopts the flow sensor to collect the flow signal to control the opening and closing of the gate to control the flow, but these gates for controlling the flow are all upward-opening gates (that is, the gate moves upward to open, and the gate moves toward Down movement is off). When the upward opening gate is used to control the flow, due to the long switching time and insensitive response, there is a certain lag. Secondly, the flow sensor requires the pipeline to be full pipe flow in application. If the pipe is not full pipe flow, the flow sensor cannot measure. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the tec...
