Built-in channel compact fast two-position three-way solenoid directional valve

Abstract

The channel built-in compact two-position three-way electromagnetic directional valve of the present invention comprises: a housing, a moving iron core, a static iron core and a plug. The moving iron core is matched with the second inner hole of the housing, and the cylindrical surface is provided with drainage grooves. Core load, the two ends of the moving iron core are cylindrical bosses at the center, which are used to block the fluid channel of the static iron core; The fifth inner hole of the housing is clearance fit, sealed by the first O-ring, and positioned axially through the end face of the first inner hole of the housing; the section of the coil support is approximately I-shaped, and the center is a stepped hole, and the coil A coil is wound around the bracket; the coil wire is led out from the sixth inner hole on the housing; an inverted L-shaped channel is opened inside the plug, which is used to guide the incoming and outgoing flow of the static iron core to the sixth inner hole of the housing. Seven inner holes are discharged, the plug is in clearance fit with the fifth inner hole of the housing, and is sealed by the second O-ring, and the plug is firmly connected with the housing.

Description

technical field [0001] The invention relates to an electromagnetic reversing valve, in particular to a channel-built-in compact and fast two-position three-way electromagnetic reversing valve. Background technique [0002] The commonly used two-position three-way electromagnetic reversing valves generally have direct-acting, diaphragm, and lever structures. At present, the electromagnetic valves of these structures have many components, and the internal structure is relatively complicated. The fluid channel and the moving iron The core and the static iron core are separated, the structural size is large, the overall mass is heavy, and the response speed is relatively slow. Many products do not even have requirements for speed. Meet the use requirements. Contents of the invention [0003] The problem solved by the invention is that the existing two-position three-way electromagnetic reversing valve has large structural size and slow response speed. In order to solve the a...
