The bimetallic thermometer flange of the relevant knowledge

Bimetallic thermometer is a kind of measuring instrument in the field of low temperature detection, can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. Powerful functions and wide scope of the bimetallic thermometer variety, is countless. According to the installation mode of connection can be divided into no fixture, male connection, threaded pipe, fixed external thread, adjustable tube joint, flange fixed and movable flange. Do you really understand the flange? Flange, foreign language called Flange, and Flange plate or Flange. Flange is connected between the pipe and pipe parts, used for the connection between the tube end, are also useful in equipment import and export, or used for the connection between the two devices, materials such as stainless steel, carbon steel, nickel steel. Hole in the flange, bolts to make two flanges, even between packing seal, are used in pairs. Different pressure flange thickness is different, they use the bolt is different also. General flange into threaded connection ( Threaded connection) Flange, welding flange and the clamp flange. Low pressure pipe flange can use silk, the use of 4 kg pressure welding flange. When water pump and valve, and pipe connection, the local equipment, also made the corresponding flange shape, also known as flange connection. Where there are two surfaces around use bolt connection closed connection parts at the same time, generally called & quot; Flange & quot; , such as ventilation pipe connections, this kind of parts can be called & quot; Flange parts & quot; 。 But this connection is only a partial equipment, such as flange connection and water pumps, is bad call pumps & quot; Flange parts & quot; 。 Relatively small, such as valve can call & quot; Flange parts & quot; 。
