Problems solved by technology

[0005] The force of the existing proportional electromagnet is constant and non-adjustable at a certain current or voltage. When the working condition changes, it takes a lot of time to adjust to make the proportional solenoid suitable for the corresponding working condition and realize the proportional control again.

Abstract

The invention discloses a proportion electromagnet which comprises a shell (1), a coil assembly (2), a pole shoe (3), a magnetic shielding ring (4), a guide sleeve (5), an iron core (6) and a push rod (7). A power connector (8) is connected onto the shell (1), a spring seat (9) is fixedly connected to the right end of the iron core (6), a through hole matched with the spring seat (9) is arranged on the right end surface of the shell (1), an adjusting screw (10) is mounted at the right end of the through hole, and a spring (11) is arranged between the adjusting screw (10) and the spring seat (9). The proportion electromagnet has the advantages that the proportion electromagnet is additionally provided with the spring seat, the spring and the adjusting screw, pre-tightening force which is applied on the iron core of an electromagnet by the spring can be conveniently changed by means of adjusting the adjusting screw, accordingly, acting force of the electromagnet at certain current or voltage can be changed, acting force of the proportion electromagnet at the certain current or voltage is adjustable, and the proportion electromagnet is simple and compact in structure, reasonable in design, convenient to adjust and high in practicality.

Description

technical field [0001] The invention relates to an electromagnet, in particular to a proportional electromagnet. Background technique [0002] The proportional electromagnet is an important part of the proportional valve. Under the action of the proportional electromagnet, the proportional valve can realize the proportional control of the pressure, flow and other parameters of the hydraulic system. The proportional control is to change the internal pressure of the proportional electromagnet through the controller. The current value passed through the coil controls the moving distance of the proportional valve spool, thereby changing the opening amount of the proportional valve port and realizing proportional control. [0003] The proportional electromagnet structure is mainly composed of an iron core, a guide sleeve, a magnetic isolation ring, a pole piece, a housing, a coil, and a push rod. A communication helical tubular control coil is arranged between the guide sleeve an...
