Magnetic valve system for controlling flowing of liquid and gas, has magnetic valve manufactured with two different structure variants such that valve is fully opened in normal state in one variant and fully closed in other variant

摘要

#CMT# #/CMT# The system has a valve body (1) for retaining a valve seat (2), and two control cones (51, 81) mirror-symmetrically arranged to each other with respect to a symmetry plane. A magnetic valve is manufactured with two different structure variants in such a manner that the magnetic valve is fully opened in a normal state i.e. not-driven state, in one of the structure variants, and fully closed in the normal state in the other structure variant. A resetting element (17) i.e. pressure screw spring, is arranged between a closure element (3) and an armature piston (9) in the former variant. #CMT# : #/CMT# The resetting element is selected form a group consisting of a helical tension spring, a disk spring and a leaf spring. An independent claim is also included for a method for manufacturing a magnetic valve. #CMT#USE : #/CMT# Magnetic valve system for controlling flowing of liquid and gas. #CMT#ADVANTAGE : #/CMT# The magnetic valve is manufactured with two different structure variants in such a manner that the magnetic valve is fully opened in the normal state in one of the structure variants and fully closed in the normal state in the other structure variant, thus avoiding manufacturing of various individual components for different types of valves, and hence simplifying structure of the valve system and reducing manufacturing cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a proportional valve with basic components of a magnetic valve system that is opened in a structure variant in a normal condition. 1 : Valve body 2 : Valve seat 3 : Closure element 9 : Armature piston 17 : Resetting element 51, 81 : Control cones.
