What is the working principle of a high-temperature solenoid valve?
The working principle of high-temperature solenoid valves mainly involves three parts: electromagnets, valve bodies, and medium flow. The following is the working principle of a high-temperature solenoid valve:
The control function of electromagnets
The high-temperature solenoid valve contains a closed chamber inside, with a piston in the middle and two electromagnets on each side. When the electromagnetic coil is energized, an electromagnetic force is generated, which attracts the piston to move in the direction of the energized electromagnet. Due to the opening of through holes at different positions in the chamber and their connection to different oil pipes, the movement of the piston will change the flow of hydraulic oil, thereby pushing the piston of the oil cylinder and driving the mechanical device through the piston rod.
The Movement of Valve Body and Medium Flow
The current flow of the electromagnet controls the movement of the piston, which in turn controls the opening or closing of the valve body. Specifically, when the coil is energized, the electromagnetic force will cause the pilot valve core to engage, the pilot hole to open, and the pressure on the valve will be relieved. The piston will be pushed by the pressure of the lower chamber medium, and the solenoid valve will open. On the contrary, when the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston throttle hole and the thrust of the reset spring, and the valve is closed.
Characteristics of High Temperature Electromagnetic Valves
High temperature solenoid valves usually use special temperature resistant and wear-resistant materials to make valve cores to ensure normal operation in high temperature environments. In addition, high-temperature solenoid valves may also have the following characteristics: the installation direction of the valve body is unrestricted and can resist corrosion and wear in high-temperature environments; The specially designed coil adopts a heat dissipation structure to prevent burning out due to prolonged inactivity.
The working principle of a high-temperature electromagnetic valve is to control the movement of the valve body through the current of the electromagnet, thereby changing the flow state of the medium. This design enables the high-temperature solenoid valve to achieve automatic and remote control functions in high-temperature environments.
