Uses
Underwater Fluid Control: It is widely applied in scenarios such as underwater irrigation systems, water flow control in aquariums, and underwater fountains. It can precisely control the on-off and flow rate of water to meet different application requirements. For example, in an aquarium, the underwater solenoid valve can accurately control the water flow speed and direction in different areas, creating a suitable living environment for various aquatic organisms.
Underwater Equipment Cooling: Some underwater equipment, such as underwater motors and sensors, generate heat during operation and need to be cooled by cooling water. The underwater solenoid valve can be used to control the circulation of the cooling water, ensuring that the equipment operates within the normal temperature range and improving the reliability and service life of the equipment.
Underwater Hydraulic Systems: In the hydraulic systems of underwater robots, submersibles and other equipment, the underwater solenoid valve is used to control the flow direction and pressure of the hydraulic oil, so as to achieve precise control of components such as robotic arms and thrusters, enabling these devices to flexibly complete various tasks underwater.
Principle
The working principle of the underwater solenoid valve is based on electromagnetic induction and the movement of the valve core. It is mainly composed of components such as an electromagnetic coil, a valve core, a valve seat, and a spring. When the electromagnetic coil is energized, a magnetic field is generated. The magnetic field exerts an attractive force on the valve core, causing the valve core to move upward against the elastic force of the spring, thus opening the valve and allowing the fluid to pass through. When the electromagnetic coil is de-energized, the magnetic field disappears, and the valve core returns to its initial position under the elastic force of the spring, closing the valve and preventing the fluid from passing through. By controlling the energization and de-energization of the electromagnetic coil, the opening and closing state of the valve can be precisely controlled, and thus the on-off control of the underwater fluid can be achieved.
Functions
On-Off Control Function: This is the most basic function of the underwater solenoid valve, which can quickly and accurately cut off or connect the water flow as needed, realizing the start-stop control of the underwater fluid system. For example, in an underwater irrigation system, according to the set time or the feedback signal from the soil moisture sensor, the on-off of the water flow can be controlled by the underwater solenoid valve to achieve precise irrigation.
Flow Regulation Function: Some underwater solenoid valves also have the function of flow regulation. By changing the opening degree of the valve core, the flow rate of the fluid can be adjusted. For example, in an underwater fountain system, by adjusting the opening degree of the underwater solenoid valve, the water flow rate and the spraying height of the fountain can be controlled, creating different fountain effects.
Remote Control Function: Combined with modern control systems, the underwater solenoid valve can achieve remote control. Through wireless communication technology or cable connection, operators can control the underwater solenoid valve from a distance, which facilitates the management and maintenance of underwater equipment and systems. For example, in deep-sea exploration equipment, scientists can remotely control the underwater solenoid valve to collect water samples at different depths or control the working status of the equipment.
