The classification of the bimetallic thermometer

The bimetallic thermometer pointer plate with the direction of protecting tube connection bimetallic thermometer can be divided into axial, radial and 135 & deg; To type and universal type four. (1) the axial type bimetallic thermometer: pointer vertical connection tube plate and protection. (2) the radial type bimetallic thermometer: pointer GuanPing line connection plate and protection. ③ 135° The bimetallic thermometer: pointer tube plate and protection into 135 & deg; Connection type (4) universal bimetallic thermometer: pointer plate connected to the protecting tube Angle can be arbitrary adjustment. Principle structure of bimetallic thermometer is round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, a free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. In order to meet the needs of practical production, bimetallic thermometer has different installation fixed form is divided into: movable external thread pipe joint, movable threaded pipe joints, fixed nipple, card sets of nipple, flange joint and a fixed flange.
