ABSTRACT:
An electromagnetic permeable-shell-free diaphragm valve comprising a shell, a coil, a stator, a magnetic flux permeable block, a spring seat, an adjusting block, a valve stem, a diaphragm, a coil spring, and a valve seat. The diaphragm of the valve isolates the slide portion of the stem from the liquid, so that the reciprocating motions of the valve stem will not be impeded when the liquid is dehydrated. Furthermore, it is not necessary to install a permeable shell, so that the manufacturing cost is lower than that of the conventional valve, and the efficiency of the heat dissipation will be improved, particularly at high-frequency operation, since the coil is directly disposed outside the shell of the valve.
