  • Publication number: 20060043323
    Abstract: A newly designed solenoid gas valve which including a solenoid assembly and inlet & outlet fittings is installed inside a tube. The adoption of in-line inlet and outlet configuration simplifies the procedures required for connecting the pipes and the gas flow is controlled by opening and closing the valve in a piping system. The opening and closing of the valve is operated by the pressure difference with an aid of the magnetic field. A compression spring is attached to the support cylindrical body and held against the inlet end fitting while a moving solenoid assembly is located inside the support cylindrical body. The moving solenoid assembly that consists of a stop, a flange, a sleeve and an electrical coil, is held by a second compression spring that is attached to the inside of the support cylindrical body. A small moving magnetic rod, slides inside the sleeve of the solenoid assembly.
