Excavator coil role

    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 powered on or 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. The electromagnetic parts of the solenoid valve are composed of fixed iron core, moving iron core, coil and other components; The valve body part is composed of spool, spool sleeve, spring base, etc. The solenoid is mounted directly on the valve body, which is enclosed in a sealed tube, forming a simple and compact combination. We commonly used in the production of solenoid valves have two three-way, two four-way, two five-way and so on. Here is the meaning of the two first: for the solenoid valve is charged and lost power, for the controlled valve is open and close.

    There are many kinds of solenoid valves, there are control gas, liquid (such as oil, water), most of them are wire trap on the valve body, can be separated, the spool is made of ferromagnetic material, by which the magnetic force generated when the coil is energized attracts the spool, and the valve is driven by the spool to open or close. The coil can be removed separately. The solenoid valve is used to control the opening or closing of the gas pipeline. The movable core in the solenoid valve coil is attracted by the coil when the valve is energized, and drives the spool to move to change the on-state of the valve.

     The structure of solenoid valve is composed of electromagnetic coil and magnetism, and it is a valve body with one or more 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 change the direction of the fluid. The burning of solenoid valve coil will cause solenoid valve failure, and the failure of solenoid valve will directly affect the action of switching valve and regulating valve. What are the reasons for the burning of the solenoid valve coil? One of the reasons is that when the coil is wet, magnetic leakage occurs due to its poor insulation, resulting in excessive current in the coil and burning. Therefore, attention should be paid to preventing rain from entering the solenoid valve. In addition, the spring is too hard, resulting in excessive reaction force, too few coil turns and insufficient suction, which will also cause the solenoid valve coil to burn.
