Title:
GAS SOLENOID VALVE
Document Type and Number:
Japanese Patent JP2020148365
Kind Code:
A
Abstract:
To enable an abutment surface 3a of an armature 3 against an electromagnet 4 and an abutment surface 4a of the electromagnet 4 against the armature 3 to be prevented from corroding due to condensed liquid, since there is the possibility that gaseous foreign matter mixed in gas for some reason condenses on the abutment surface 3a and the abutment surface 4a when there is various temperature changes, in a gas solenoid valve comprising the electromagnet 4 attracting the armature 3 connected to a valve element 2 through a valve stem 21 against energization force of energization means 5.SOLUTION: Heating means is provided for heating an abutment surface 3a against an electromagnet 4 of an armature 3 and an abutment surface 4a against the armature 3 of the electromagnet 4. The heating means is preferably composed of a heater 8 mounted on an outer surface of a valve cage 1.SELECTED DRAWING: Figure 1
