Pressurizing and flow stabilizing automatic controller of non-negative-pressure pipe network

Abstract

The invention provides a pressurizing and flow stabilizing automatic controller of a non-negative-pressure pipe network. The pressurizing and flow stabilizing automatic controller comprises a flow stabilizing compensator, a control cabinet and a water supply device. A filter membrane and a reverse flow forming device are arranged in the flow stabilizing compensator. A negative pressure gauge, a valve, a filter, a backflow preventer, an antifouling cut off valve and an ozone generator are sequentially arranged between a running water outlet and an inlet of the flow stabilizing compensator. A liquid level controller, an inlet pressure sensor and a vacuum suppressor are arranged on the top of the flow stabilizing compensator. A security filter and a teletransmission pressure gauge are arranged on an outlet of the flow stabilizing compensator. An outlet pressure sensor is arranged on the outlet of the water supply device. A pressure stabilizing tank, an overpressure protection device, an outlet pressure sensor and a water outlet filter are sequentially arranged between the outlet of the water supply device and a user pipe valve, the user pipe valve is connected with a user water pipe, and a pressurizing pump set and the outlet pressure sensors are connected with the control cabinet. The pressurizing and flow stabilizing automatic controller achieves the purpose of energy-saving non-negative-pressure water supply, and water use safety is guaranteed.

Description

technical field [0001] The invention relates to an automatic controller for pressurization and steady flow of a non-negative pressure pipe network, which belongs to the technical field of water supply. Background technique [0002] With the development of the city, the secondary pressurized water supply equipment and technology of high-rise buildings have been continuously improved. In recent years, a new water supply method - non-negative pressure water supply is being gradually popularized and used. Usually, the water supply pressure of the urban municipal pipe network is set to meet the requirements of ordinary multi-storey buildings to set the water supply pressure of the water plant. Today's urban buildings are growing rapidly, and most buildings must use secondary pressurized water supply to meet water supply needs. my country's urban secondary pressurized water supply mode has experienced "reservoir, pressurized pump, water tower", "reservoir, pressurized pump, high-...

AI Technical Summary

Problems solved by technology

[0005] Although the application of non-negative pressure water supply is becoming more and more widely used, there are still some problems. The core of non-negative pressure water supply is the pressurization and steady flow control device. At present, there are still some problems with this related device, such as the inability to guarantee the safety of water quality, When the flow rate is small at night, the phenomenon of frequent start and stop of the pump, etc.
