Abstract

The invention belongs to the technical field of self-locking valves, and particularly relates to a permanent-magnet type self-locking valve. According to the permanent-magnet type self-locking valve,an outlet pipe, a first magnetic insulation ring, a magnetic guiding ring, a second magnetic insulation ring and a right skeleton are connected in a welded mode to form a coil skeleton; a permanent magnet assembly is arranged on the outer circle of the magnetic guiding ring in a sleeving mode, and a staring coil and a closing coil are wound around the outer circle of the coil skeleton and are located on the left side and the right side of the permanent magnet assembly correspondingly; the coil skeleton is sleeved with a shell, and the shell is connected with the outlet pipe and the right skeleton in a welded mode; a valve core is located in an inner hole formed by the first magnetic insulation ring, the magnetic guiding ring and the second magnetic insulation ring, and a spring is arrangedbetween the outlet pipe and the valve core; an inlet pipe is screwed into the right skeleton, the juncture of outer circles of the inlet pipe and the right skeleton are welded and fixed; and a filterassembly is fixedly mounted in an inlet pipe inner hole. The permanent-magnet type self-locking valve has the characteristics of the compact structure, the low weight, the small size, the high reliability of the whole valve and the high anti-pollution ability.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic valves, in particular to a permanent magnet self-locking valve. Background technique [0002] As an electromagnetic switch element, the self-locking valve is widely used in the industrial and aerospace fields. Usually its self-locking methods include mechanical self-locking, permanent magnetic self-locking and so on. Due to its simple structure, high reliability, compact size and many other advantages, the permanent magnet double-position self-locking valve has been more and more widely used in the civil industry and the aerospace field. [0003] The bistable permanent magnet self-locking valve of the prior art mainly has the following problems: [0004] 1) The structure is complex, heavy, bulky, and poor in maintainability, which cannot meet the requirements of compact structure, light weight, and miniaturization of aerospace vehicles. [0005] 2) The working reliability is low, the co...
