Miniature high-pressure electromagnetic valve

Abstract

The invention provides a miniature high-pressure electromagnetic valve which comprises a metal coil framework, a fixed iron core fixed to one end of the coil framework and a coil winding installed on the coil framework, and a screw joint part is arranged at the end, facing the coil framework, of the fixed iron core. The screw joint part extends into the coil framework and is in threaded connection with the coil framework, and the ratio of the length of the part, extending into the coil winding, of the screw joint part to the axial length of the coil winding is 1 / 5-1 / 3: 1; a first magnetizer is arranged at one end, far away from the screw joint part, of the fixed iron core, a second magnetizer is sleeved at the other end of the coil framework, and the thickness of the first magnetizer and the thickness of the second magnetizer are 1-3mm; the miniature high-pressure electromagnetic valve overcomes the defects that an existing electromagnetic valve is complex in structure, large in size, poor in strength, small in magnetic field force and short in service life.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a miniature high-pressure solenoid valve. Background technique [0002] Existing solenoid valve coils are generally wound on a plastic skeleton, then placed on the magnetic isolation tube assembly, and then the movable iron core is inserted into the cavity. This design idea has not changed for decades, not only has many accessories but also has poor strength. At the same time, conventional solenoid valves are all T-shaped designs with low entry and high exit, and the installation space of solenoid valves is large, especially in the fields of aircraft and deep sea, where there are special requirements for the weight, volume and installation method of components, they are all limited. In addition, it is a difficult problem to achieve high pressure with small volume and low power. Usually, such high-precision supporting equipment needs to be customized from some international giants, ...
