The electromagnetic solenoid valve is a type of valve that operates using an electromagnet. When the solenoid coil is energized, it generates a magnetic field that moves the iron core (the valve element) inside the coil, allowing the valve to open or close. Once the power is removed, the core returns to its original position either through a spring mechanism or by gravity, enabling the system to control the flow of fluids automatically. This makes solenoid valves widely used in automation systems, household appliances such as electric ice machines and washing machines, and in jet thermostats, among other applications.
Solenoid valves can be categorized into AC and DC types based on the power source they use. Depending on their function, they are generally divided into three main groups: directional control valves, pressure control valves, and flow control valves. These valves play a crucial role in directing or blocking the flow of liquids or gases within a system, making them essential components in many industrial and consumer applications. Their reliability, fast response time, and ease of integration into automated systems make them a popular choice across various industries.
The square nut is one of the welding nuts. The welding method is believed to be known to all. It is to use high temperature to melt some metal and weld it between the two products to play a fastening role. The fastening effect of this connection will be very good and will not be easy to loosen. It can also be used with bolts. Square nuts are mainly used in electric power engineering, road traffic, home building materials and other industries.
