We know that solenoid valve belongs to one of the industrial equipments controlled by electromagnetic. It is a common automatic component and is often used to control various fluids. In fact, it is a kind of actuator and has many types. For example, pneumatic solenoid valve is one of them, which can block or leak different oil discharge through controlling the movement of the valve body. Then what is the working principle of solenoid valve parts? This article will take you to understand how solenoid valves tool work.
First of all, we have a preliminary understanding of solenoid valves. In daily life, solenoid valve is widely used in different industry applications. It is composed of solenoid coils and magnetic cores, and it is a valve body containing one or more holes. When the coil is power on or power off, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off to achieve the purpose of changing the direction of the fluid. In the solenoid valve, there is a closed cavity with holes at different positions. Each hole connects with a different tube. The valve body is in the middle of the cavity, and there are two electromagnets on both sides.
Generally speaking, the working principle of solenoid valve device is that it uses the compressed air to push the multiple sets of combined pneumatic pistons to move in the actuator, and the force is transmitted to the beam and the inner curve track, which drives the hollow spindle to rotate. The compressed air is sent to each cylinder, and the air inlet and outlet positions are changed to change the direction of spindle rotation according to the requirements of the load rotation torque. The number of cylinder combinations can be adjusted to drive the load to work.
Usually the two-position five-way solenoid valve is used in conjunction with a double-acting pneumatic actuator. The two-position is controllable in two positions: on-off. The five-way valve has five channels for ventilation, of which one is connected to the air source, and two are connected to the inlet and outlet ports of the outer chamber of the acting cylinder with the double acting, and the two are connected with the inlet and outlet ports of the inner chamber. Of course, the specific working principle also can refer to the working principle of the double-acting pneumatic actuators.
According to the principle, solenoid valves are divided into three categories: direct-acting, distributed direct-acting, and pilot-operated. But according to their structure, they are divided into two types: diaphragm solenoid valves and piston solenoid valves. With the development of society, solenoid valve components can cooperate with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed. Generally each part of the mechanical equipment has an inseparable effect on the normal operation of the equipment. For example, as a part of the oil filter unit, the solenoid valve equipment plays a very important role in the normal operation of the oil filter unit.
