A ROTATORY MAGNET VALVE

摘要

A pocket rotatory magnet valve used in constant temperature water heater controls the outflow of fuel gas. The valve comprises a rotatory magnet actuator and a butterfly valve which is connected coaxial with said actuator. Said magnet actuator includes a stator, a rotor which is located in said stator, and a return spring Moreover, said valve includes a valve body and a valve plate. Said rotor's shaft extends into said valve body's channel through a supporting passageway. The butterfly valve plate is mounted on said shaft within said channel. The present application has advantages of compact configuration, sensitive and reliable control, high-definition, small backlash, precise location and well linearity etc.. In addition, said valve body adopts a plug-type configuration so as to assemble and disassemble easily.
