SAFE GUARD FOR TEMPERATURE CONTROLLER Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: safe guard for temperature controller is designed for prevention of theft and damage and for attachment of rotary handle on body of temperature controller. Handle is used to set specified value of temperature in correspondence with turn angle determined beforehand. Safe guard has protection enclosure embracing joint between body of temperature controller and adjustment valve on one side and rotary handle on other side. Enclosure is joined to body and handle with registration against turning. Joining member is placed between rotary handle and protection enclosure. Member is tailored for connection with handle and protection enclosure with registration against turning or with provision for limited turning of rotary handle with reference to body of temperature controller for adjustment of specified value of temperature within range between two ultimate values of specified quantity. At least one ultimate value can be chosen by means of connection of joining member with registration against turning in some angular position relative to rotary handle which corresponds to this ultimate value of specified quantity. EFFECT: simplified design, improved functional reliability. 7 cl, 8 dwg
