Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, and more specifically, to an energy-saving coil for electromagnetic valves. Background Art

[0002] The solenoid valve is composed of an electromagnetic coil and a magnetic core, and is a valve body containing one or several holes. When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off, so as to achieve the purpose of changing the direction of the fluid. The electromagnetic components of the solenoid valve are composed of a fixed iron core, a moving iron core, a coil and other components. Most of the time, the coil is sleeved on the valve body and can be separated. The valve core is made of ferromagnetic material, and the valve core is attracted by the magnetic force generated when the coil is energized, and the valve core pushes the valve to open or close.

[0003] In the prior art, the most common failure of the solenoid valve coil is the burning of the coil. There are many reasons for the burning of the solenoid valve coil, mainly because the solenoid valve coil will generate a lot of heat during long-term operation, which makes its internal temperature rise and causes the coil to burn easily. However, the assembly process of the existing conventional solenoid valve coil is relatively cumbersome and time-consuming, the assembly efficiency is low, and it is not convenient to replace it after burning.

[0004] Therefore, it is necessary to provide an energy-saving coil for a solenoid valve to solve the above problems. Utility Model Content
