IN-TUBE SOLENOID GAS VALVE

摘要

A solenoid gas valve having a solenoid assembly and inlet 2 and outlet 3 fittings is installed inside a tube. The opening and closing of the valve is operated by the pressure difference with an aid of the magnetic field. A compression spring 5 is attached to the support cylindrical body 4 and held against the inlet end fitting 2 while a moving solenoid assembly 6 is located inside the support cylindrical body 4. The moving solenoid assembly 6 that consists of a stop 9, a flange 10, a sleeve 8 and an electrical coil 11, is held by a second compression spring 12 that is attached to the inside of the support cylindrical body 4. A small moving magnetic rod 15 slides inside the sleeve 8 of the solenoid assembly 6. Acted by a third compression spring 17, the magnetic rod 15 seals the gas outlet through the bleed orifice 33 on the flange 10 of the solenoid assembly 6.
