Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically to an electric three-way valve with leakage monitoring function. Background Technology

[0002] Three-way valves, as common fluid control devices, are widely used in industrial, building, and domestic water supply and heating systems to control the diversion or merging of fluids. Traditional three-way valves are typically driven manually or mechanically, relying on manual operation to adjust their opening and closing states, lacking automated control capabilities. However, in practical applications, these valves exhibit the following significant problems: Lacking leakage detection capabilities, ordinary three-way valves cannot monitor leaks in pipes or connections in real time. When a leak occurs in the system, it requires manual detection and intervention, which may lead to water waste, equipment damage, or even safety accidents. Non-electric drive, slow response speed: Traditional valves are mostly driven manually or mechanically, and cannot close automatically and quickly in the event of leakage or other emergencies, making it difficult to meet the real-time and reliability requirements of modern intelligent fluid control systems; The low level of intelligence means that existing three-way valves typically do not integrate sensors or electronic control modules, making them unable to connect with smart home and IoT systems, thus limiting their application in automated management scenarios.

[0003] In summary, traditional three-way valves mostly use manual or mechanical actuation, which has the following problems: 1. They cannot monitor leaks in real time, rely on manual inspection, and are prone to water waste and equipment damage; 2. They have slow response speed and cannot quickly shut off when a leak occurs; 3. They have low intelligence and are difficult to link with intelligent systems.

[0004] To address the aforementioned issues, there is an urgent need to design an electric three-way valve with leakage detection capabilities. By integrating sensors and an electric drive device, it can achieve real-time detection and automatic shut-off of leaks, thereby improving the system's safety and intelligence. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the aforementioned problems, this application proposes an electric three-way valve with leakage detection function. This electric three-way valve with leakage detection function integrates sensors, electric drive, and a wireless communication module to achieve automatic leakage detection, rapid valve closure, and remote control, thereby improving the system's safety and intelligence level.

[0006] To achieve the above objectives, the following technical solution is adopted: An electric three-way valve with leakage detection function includes a three-way valve body, a valve knob on the top of the three-way valve body, and an electric control mechanism on the top of the three-way valve body. The bottom of the electric control mechanism is sealed to the valve knob. The electric control mechanism includes a base that is sealed to the valve knob. The base has an internal receiving space, and a motor and an electric control board for controlling the operation of the motor are arranged inside the base. The electric control board is connected to the motor, and the output end of the motor is drivenly connected to the valve knob. The electric control board is externally connected to a power supply line for providing power and a probe line for monitoring the water source. The probe line is equipped with a monitoring sensor probe.

[0007] Furthermore, the base has an opening at the top and is fitted with a sealing cover, and the sealing cover is fitted with a cover sealing ring.

[0008] Furthermore, the motor is located at the bottom of the base, and the motor output end is connected to the valve knob via a transmission. The motor cover is equipped with an electronic control board, and a sealing cover is arranged on the electronic control board. The sealing cover is closed on the top of the base and seals with the base.

[0009] Furthermore, a display panel is fitted onto the sealing cover, the display panel is arranged on the surface of the sealing cover, and passes through the sealing cover to be connected to the electronic control board.

[0010] Furthermore, the sealing cover is fixed to the base by cover screws, and a screw sealing gasket is provided on the cover screws.

[0011] Furthermore, both the power cord and the probe wire are fitted with clamping plates inside the base, and the clamping plates are fixed to the base by clamping screws.

[0012] Furthermore, the power cord passes through the side wall of the base and enters the base, and a power sealing gasket is provided on the side wall of the base to fit the power cord.

[0013] Furthermore, the probe line passes through the side wall of the base and enters the base, and a probe sealing gasket is installed on the side wall of the base to cooperate with the probe line.

[0014] Furthermore, the top of the three-way valve body is sealed to the bottom of the base via a valve sealing ring.

[0015] Furthermore, the electronic control board integrates a Wi-Fi, Bluetooth, or LoRa communication module.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Real-time leak monitoring enhances safety. This valve integrates a high-sensitivity leak sensor to monitor leaks in pipes or connections in real time. Once a leak is detected, the system immediately triggers an alarm and automatically shuts off the valve, effectively preventing water waste, equipment damage, and potential safety accidents, significantly improving system reliability. Electrically driven for rapid response, the valve opens and closes using an electric actuator, offering a much faster response time compared to traditional manual or mechanical valves. Upon detecting a leak, the valve can be closed within seconds, minimizing leakage losses.

[0017] Intelligent control and remote management: Valves can be integrated with communication modules such as Wi-Fi, Bluetooth or LoRa to link with smart home systems, industrial IoT platforms or mobile APPs to achieve remote monitoring, fault alarm and automatic control, meeting the needs of modern smart water management, smart buildings and other scenarios. Energy-saving and environmentally friendly, reducing operation and maintenance costs, through automatic detection and rapid leak sealing, it can significantly reduce water waste and equipment damage caused by pipeline leaks, reduce manual inspection and maintenance costs, and conform to the development trend of green energy conservation.

[0018] High safety: Real-time monitoring + quick valve shut-off effectively prevents water leakage losses; Meanwhile, this three-way valve is waterproof and durable, and features a multi-seal design to adapt to humid environments. Attached Figure Description
