Embodiment approach

[0034] Combine figure 1 with figure 2 As shown, according to an embodiment of the present invention, a position measuring device of the Hall sensor, comprising: a Hall sensor 11, magnetic steel 12, which is opposed to the Hall sensor 11, is used to connect Hall. The sensor 11 and the magnetic steel 12 are used for magnetic magnetic ring 13, corresponding to the Hall sensor 11 and the magnetic steel 12, and the first magnetic splitting member 14, which is disposed, and two first magnetic splitters located opposite. 14 The second magnetic passage 15 between 14. In the present embodiment, the magnetic ring 13 is integrated, the Hall sensor 11 and the magnetic steel 12 are disposed relative to the inside of the magnetic ring 13, and the Hall sensor 11 and magnet steel 12 are respectively connected to the magnetic ring 13, respectively. Depending on, the polar Sole (or N pole) connected to the magnetic steel 12 and the magnetic tone ring 13 is connected to the Hall sensor 11 and the me...

Abstract

The invention relates to a position measuring device based on a Hall sensor and a solenoid valve. The position measuring device includes: a Hall sensor, and a magnetic steel opposite to the Hall sensor for connecting the Hall sensor and the Magnetic steel and a magnetically permeable ring used for magnetic conduction, a first magnetic flux member corresponding to the Hall sensor and the magnetic steel and arranged oppositely, and located between the two opposite first magnetic flux members The second magnetic flux member; the Hall sensor and the magnetic steel respectively abut against one end of the first magnetic flux member corresponding thereto; the outer surface of the second magnetic flux member (15) is at least A groove (151) is provided; along the direction perpendicular to the connecting line of the two first magnetic flux members, the second magnetic flux member can move linearly back and forth. The position measuring device of the invention is simple and flexible in structure, and has high measurement accuracy and sensitivity.

Description

Technical field [0001] The present invention relates to the field of mechanical, and more particularly to a position measuring device and a solenoid valve based on a Hall sensor. Background technique [0002] Double steady-state solenoid valve is an electric valve having a position self-holding function, has an enable / closed instant energy consumption, passive retention, long life, and a management valve for isolation control for fluid media, in industrial and agricultural production, Defense, aerospace, etc. have been widely used. For its passive retention characteristics, due to vibration, acceleration, fault incentives, the steady state position of the electromagnetic valve-core jump is made, and there is no corresponding spool tube measurement means, the control system where the solenoid valve is not known. The real state of the valve is not possible to take remedial measures in time. [0003] Currently, there are two methods of dielectric contact and non-contact formula. M...
