Electromagnetic gas control valve - has resilient gas seal compressed between two conical surfaces to accommodate mfr. tolerances
Реферат: An electromagnetic valve is designed to control a gas supply. It has a stem (8) for connection to a gas bottle and there is a magnet core (5) secured to the stem (8) by a rivet (7) but electrically insulated by insulators (2). The excitation coil is soldered at one end (3) to the rivet (7) which engages by way of seat (6) a thermocouple at (14) when installed. On assembly of the valve an annular resilient seal (13) is squeezed between two conical surfaces (10, 11) on the stem (8) and the rivet (7) respectively. The seal element compensates for tolerances and providing a good gas seal.
