Problems solved by technology

[0003] In order to solve the technical problem that the existing water supply equipment does not have a flow monitoring device, when the vacuum suppressor installed on the steady flow tank cannot work normally, it will cause vicious water supply accidents such as the suction of the steady flow tank, etc., and provides a water supply system. The flow monitoring device of the equipment can monitor the flow of the water supply network in real time to ensure the safety of the water supply network

Abstract

The invention provides a flow monitoring device for non-negative pressure water supply equipment, which comprises a water inlet pipeline. The water inlet pipeline is connected with a current stabilizing tank; the current stabilizing tank is connected with a water pump set; the water pump set is connected with a water outlet pipeline; a backflow preventer is arranged on the water inlet pipeline; a flow monitor is arranged behind the backflow preventer and connected with an intelligent controller through an electric signal; and the intelligent controller is connected with the water pump set through the electric signal. Through the flow monitoring device, the flow of a pipe network can be monitored in real time, malignant water supply accidents such as flat current stabilizing tank due to adsorption when a vacuum suppressor on the current stabilizing tank cannot normally work are avoided, and the water supply safety is ensured.

Description

technical field [0001] The invention relates to a flow monitoring device, in particular to a flow monitoring device for water supply equipment. Background technique [0002] At present, the water supply equipment in the existing technology, including the non-negative pressure water supply equipment, does not have a flow monitoring device. The control of the flow of the pipe network adopts the method of setting a vacuum suppressor on the steady flow tank. When the water volume of the pipe network exceeds the normal water supply volume of the municipal pipe network , When negative pressure is caused to the pipe network, the negative pressure is eliminated through the vacuum suppressor to ensure safe and stable water supply. However, the vacuum suppressor cannot work normally in some specific occasions (such as plateau areas), or when the vacuum suppressor fails, the negative pressure of the pipe network cannot be eliminated, and the steady flow tank of the water supply equipme...
