Description
Technical Field
[0001] The utility model relates to the technical field of electromagnets, in particular to an electromagnet capable of adjusting the position of a manual push rod. Background Art
[0002] As a new type of electro-hydraulic control element between on-off control and servo control, the solenoid proportional valve continuously and proportionally controls the pressure, flow, and direction in the hydraulic system according to the electrical signal, and can prevent hydraulic shock. Due to its structural design, process performance, and price, which are between on-off control elements and servo control, it has been widely used in recent years. As the control element of the solenoid valve, the electromagnet plays a vital role in the solenoid valve.
[0003] The electromagnet core tube and magnetic shield are accessories used for electromagnets, primarily for controlling and adjusting the distribution of the electromagnet's magnetic field. Electromagnets operate by utilizing the magnetic effect of electric current. The on / off or changing current generates a magnetic field, which in turn drives the core or other components. The core tube is a crucial component within the electromagnet, concentrating and directing the magnetic field. The shield is a specialized accessory used to isolate the magnetic field between different parts of the electromagnet, preventing it from interfering with or affecting the normal operation of other components.
[0004] 1. Magnetic field isolation: The magnetic isolation sheet can effectively isolate the magnetic field between different parts of the electromagnet, preventing the magnetic field from spreading to unnecessary areas, thereby reducing interference with surrounding equipment;
[0005] 2. Adjust the magnetic field distribution: Through the reasonable design and installation of magnetic isolation sheets, the magnetic field distribution of the electromagnet can be adjusted and optimized to make it more concentrated and efficient;
[0006] 3. Protect other components: The magnetic isolation sheet can also protect other components inside the electromagnet, such as circuits and other sensitive components, from interference and damage by strong magnetic fields.
[0007] However, the utility model has the following problems when it is actually used:
[0008] 1. The manual push rod of the electromagnet is used for manual control during debugging or emergency situations. When the system back pressure is high and adjustment is difficult, tools such as a cross screwdriver are used to push the manual push rod. When the impact force increases, the manual push rod or the guide inner hole surface may be damaged, causing the electromagnet to leak oil or fail to reset.
[0009] 2. It is impossible to adjust the suction of the tongue iron at different positions. If you want to achieve this goal, you need a variety of lyrics sheets with different thicknesses, which results in high processing costs and complicated assembly. Utility Model Content
