温度控制仪

流体(ti)(ti)媒(mei)介温(wen)(wen)(wen)(wen)度(du)(du)(du)控(kong)(kong)制(zhi)器是利(li)用(yong)感温(wen)(wen)(wen)(wen)流体(ti)(ti)热(re)胀冷缩(suo)(suo)及液体(ti)(ti)不可压(ya)缩(suo)(suo)的原(yuan)理而实现自动调节。当(dang)控(kong)(kong)制(zhi)温(wen)(wen)(wen)(wen)度(du)(du)(du)升高时感温(wen)(wen)(wen)(wen)液体(ti)(ti)膨胀产生的推力将热(re)媒(mei)关小,以降低(di)输出温(wen)(wen)(wen)(wen)度(du)(du)(du);当(dang)控(kong)(kong)制(zhi)温(wen)(wen)(wen)(wen)度(du)(du)(du)降低(di)时感温(wen)(wen)(wen)(wen)液体(ti)(ti)收缩(suo)(suo),在复位装置的作(zuo)用(yong)下将热(re)媒(mei)开大,以提高输出温(wen)(wen)(wen)(wen)度(du)(du)(du),从而使被控(kong)(kong)制(zhi)的温(wen)(wen)(wen)(wen)度(du)(du)(du)达到和保持在所设定(ding)的温(wen)(wen)(wen)(wen)度(du)(du)(du)范围内。
