Background
The solenoid valve is widely used in various fluid control systems because of its simple structure and operation principle. The structure of the traditional electromagnetic valve is shown in figure 1 and mainly comprises a valve body, a recovery spring, an electromagnetic coil, a mandril, a valve port and an armature; when the electromagnetic valve is not electrified, the ejector rod of the electromagnetic valve pushes the conical valve port under the action of the spring force, so that the valve port is closed, and the electromagnetic valve is kept in a normally open state; when the valve is electrified, the magnetic force generated by the coil attracts the armature to move upwards against the spring force, so that the valve port is opened. The electromagnetic valve is kept in an open state by continuous energization until the electromagnetic suction force disappears when the power is off, and the valve port is compressed by the ejector rod under the action of the spring force again to close the valve.
The existing electromagnetic valve adopts a mechanical spring as a recovery mechanism, and if the valve is to be kept in an open state, a coil must be continuously electrified, so that an ejector rod can always compress the spring, and a valve port is unobstructed. However, mechanical springs present two major drawbacks. Firstly, as the opening times of the electromagnetic valve increase, the mechanical spring inevitably loses efficacy, which is mainly represented by the change of the spring stiffness, and the spring stiffness gradually decreases along with the increase of the expansion times, which leads to the reduction of the force of the mandril pressing the valve port, so that the valve port is sealed insecure. Secondly, energy consumption is large. The valve can be kept in an open state only by continuous electrification, the valve is longer in opening time and more obvious in energy consumption in many occasions, and the valve generates serious heating phenomenon due to serious copper loss caused by long-time electrification. In addition, the structure of spring and ejector pin is very unfavorable for the miniaturization of solenoid valve, and in the occasion that space size required is higher, traditional solenoid valve is obviously not suitable for.
