Bimetallic thermometer classification and selection of the technique

The classification of the bimetallic thermometer 1, classification and selection guidelines by bimetallic thermometer pointer plate with the direction of protecting tube connection bimetallic thermometer can be divided into axial, radial and 135 ° to the model and universal model. (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) type 135 ° to the bimetallic thermometer: pointer plate connected to protection tube into 135 °. (4) universal type bimetallic thermometer: pointer plate connected to the protecting tube Angle can be arbitrary adjustment. 2, the installation of the bimetallic thermometer fixed form in order to meet the needs of practical production, bimetallic thermometer has different installation fixed form: movable external thread pipe joint, movable threaded pipe joints, fixed nipple, card sets of nipple, flange joint and a fixed flange. 3, bimetallic thermometer model naming W S S - - - — No - form of protection W - type of permanent way Protection type 0 No fixed device F - 1 - to anti-corrosion type structure Movable external thread 0 2 - axial type Movable internal thread 1 - 3 - radial type Fixed screw 2 - 4-135 ° to type Fixed thread 3 - 5 - universal type 6 - card set of threaded casing of nominal diameter 3 - card flange φ60 4 - φ100 5 - Phi 125 thermal element is double metal metal expansion type temperature instruments Classification and selection of bimetal thermometers 1. 分类、双金属温度计可分为轴向型、径向类型,135年 方向型和通用型根据刻度盘之间的连接方向和保护管。 1轴向双金属温度计:表盘是垂直连接到保护管。 2径向双金属温度计:指针板和保护管并联。 3135定向双金属温度计:拨打135连接到保护管。 4通用双金属温度计:指针盘和保护管连接的角度可以任意调整。 2. 双金属温度计的安装和修复,以满足实际生产的需要,双金属温度计,可在各种各样的安装和固定模式:外部螺杆联轴器,内部螺杆联轴器,固定螺杆联轴器,snap - 在螺杆联轴器,snap - 在凸缘联轴器和修复法兰。 3. 双金属温度计类型命名为类型W S□□□□,非保护形式 常见型、固定型0 - W保护类型 non- 固定设备f - corrosion type, structural type 1- 可移动的外螺纹0 - 轴向式2 - 可移动的内部线程1 - 径向式3 - 固定线程2 - 1354 - 固定线3 - 通用型5 - 夹线,公称直径6 - 夹法兰3 - 604 - 1005 - 125年温度传感器是双金属、金属扩张、温度仪表
