Intermittent intelligent water replenishment control system for water container

Abstract

The invention discloses an intermittent intelligent water replenishment control system for a water container. The water container is equipped with a remote control floating ball valve and has a waterinlet connected with a municipal pipe network. The intermittent intelligent water replenishment control system comprises a controller, an electric flow valve, an electric switch valve, a pressure sensor and a liquid level sensor. The liquid level sensor is arranged at the bottom of the water container for real-time detection of a liquid level value in the water container. The electric flow valve and the electric switch valve are connected in series to the control pipeline. The water inlet of the control pipeline is connected with the municipal pipe network, and the water outlet of the controlpipeline is connected with the control port of the remote control floating ball valve. The pressure sensor detects the pressure value of the municipal pipe network in real time. The controller, when acurrent liquid level drops to a lower limit liquid level, opens the electric switch valve and controls the opening and closing degree of the electric flow valve according to the current pressure value, and when the current liquid level rises to the upper limit liquid level, turns off the electric switch valve. The intermittent intelligent water replenishment control system can intelligently control the water replenishment flow rate, thereby protecting the municipal pipe network.

Description

technical field [0001] The invention relates to the technical field of municipal water supply, in particular to an intermittent intelligent water supply control system for a water storage container. Background technique [0002] The current urban water resources planning is far behind the development of the city, and the contradiction between urban water supply capacity and residents' water demand has become increasingly prominent. At present, most water points are equipped with water storage containers such as water tanks and pools. When the water storage container needs to replenish water, the traditional float control device is used to draw water from the municipal pipe network, which will cause the pressure of the pipe network to drop sharply during the peak water consumption period. , Seriously affecting the water quality of urban water supply and the safety of water supply facilities, affecting the normal water use of residents. And because the water replenishment of ...

Problems solved by technology

At present, most water points are equipped with water storage containers such as water tanks and pools. When the water storage container needs to replenish water, the traditional float control device is used to draw water from the municipal pipe network, which will cause the pressure of the pipe network to drop sharply during the peak water consumption period. , seriously affecting the water quality of urban water supply and the safety of water supply facilities, affecting the normal water use of residents

And because the water replenishment of the water storage container is mechanically controlled, it cannot be adjusted according to needs, causing the water in the water storage container to be always full, causing insufficient water circulation in the water storage container, deteriorating water quality, affecting the lives and health of residents, and the floating ball The floating ball of the control device is soaked in water for a long time. After being corroded, it will lose the ability to control water inflow, which will easily cause overflow and waste water resources, and will endanger the safety of water supply units and underground facilities such as elevators, machine rooms and backup power systems.

At the same time, the water storage container does not play the role of high and low peak storage and real-time flow calculation function. Due to the high cost of installing flow meters, most of them are not installed with metering instruments, so they cannot provide water consumption data in time, and cannot provide production scheduling basis for water supply companies, resulting in During the peak period of water consumption, the flow of the pipe network is large, and the production equipment runs at full capacity, resulting in high construction and operation management costs
