Currently, low-pressure electrically controlled large-diameter valves used in water supply and drainage applications mainly have two control methods: one is driven by 220VAC alternating current, and the other is driven by a direct current power source. AC power is generally used to control large linear valves, but due to the constraints imposed by actual field conditions, it is often difficult to obtain AC power. Moreover, the additional energy consumption places a burden on users or management teams; therefore, it is not the best control method for low-pressure pipelines. The DC power supply method generally uses an adapter power supply or battery with a voltage of no more than 24VDC; the water pressure in the pipeline is utilized to drive actuators such as motor valves and solenoid valves that control the opening and closing of water passages. Among these, battery power supply can minimize the impact of electromagnetic interference on the control system, and it eliminates the need for an AC power source on-site, thereby reducing control costs and enhancing product reliability; hence, battery power supply is widely adopted. In battery-powered solutions, disposable lithium batteries and alkaline batteries are currently used. Relatively speaking, lithium batteries of the same volume can store more energy than alkaline batteries, allowing them to operate for a longer time. Therefore, lithium batteries are still the mainstream choice in the market as electric power sources for large-diameter valves. However, lithium batteries suffer from passivation (also known as the memory effect) to a certain extent; they are prone to failure, and there are also issues related to environmental impact. On top of that, it is difficult to ensure consistency in lithium battery products, and different loads result in varying discharge curves. As a result, in practical applications, lithium batteries present challenges that neither users nor manufacturers can control. On the other hand, the pilot valves currently used for low-voltage control (which are different from the large-diameter valves mentioned earlier), whether electromagnetic or motor-driven, operate on the principle that a pilot valve driven by low voltage is used to relieve pressure in the valve sealing chamber (i.e., the pressure relief chamber), thereby enabling the use of the water pressure in the pipeline to open the main valve (i.e., the main valve body of the large-diameter valve mentioned earlier) or the valve seal. Similarly, it also achieves the purpose of closing the main valve by utilizing the water pressure in the chamber, by shutting off the pressure relief chamber. However, in the actual use of water supply pipelines in our country, problems have arisen due to long-term water quality issues, such as the blockage of the flow guide holes in the pilot valve, as well as the accumulation of iron particles or small sand grains on the pressure relief valve stem, which causes the stem to get stuck. Additionally, some designers lack practical experience and fail to adequately assess the actual conditions on site; as a result, there are defects in the design of the valve drive circuits and control software, leading to a higher failure rate for such valves over time. In addition to the aforementioned issues, low-pressure water supply and drainage valves in China are currently mostly equipped with simple mechanical or electrical control systems, or even manual control, resulting in a low level of intelligence. Some products use communication methods such as RS-485, infrared, GSM, and Zigbee for centralized or remote management in their applications. While this improves the level of intelligence of these products to some extent, it also has its drawbacks: issues such as low communication speeds, high installation costs, high failure rates, inflexible networking, limited network capacity, high power consumption, and complex protocols. These problems not only increase the difficulty for designers in developing such products but also hinder the improvement of users’ ability to manage them. This is particularly problematic in the context of commercial water usage, as it creates difficulties in charge management. In summary, the power supply, routine maintenance of valve actuators, as well as intelligent control and management represent the weak points in current valve applications. It is necessary to find cost-effective and widely applicable technologies and solutions to improve the performance of existing electrically controlled valves.
