Steam decompression valve for iron, has steam pressure exceeding elasticity of safety spring and pushing piston valve group, when pressure at steam outlet is strong, and connecting section of group separated from locking section of base

摘要

The valve has a piston valve group (200) coupled with an inlet passage of a fixed base (100). The group has a lower part with a connecting section (270) coupled with a locking section (160) of the base. A safety spring (300) raises the group, so that the group seals the passage, and the section (270) is coupled with the section (160). Steam pressure exceeds elasticity of the spring and pushes the group to be mounted when the pressure at steam outlet of a steam generator is strong, and the section (270) is separated from the section (160).
