Method of producing a hydraulic link between a temperature sensor and a tap in a central heating system controlled by the sensor

摘要

One end of the capillary tube (4) is attached in a leakproof manner to the liquid-filled temperature-sensitive bellows of the thermostatic device (1). The capillary (4) passes axially through the tubular bobbin (21) and leaves radially through the end flange (41). It then winds around the bobbin, forming the number of turns required to take up the length of the tube in excess of the useful length; it then passes behind the bracket (2) and follows a suitable path up to the tap (6) of the radiator (7). The other end of the capillary tube (4) is connected in a leakproof manner to the bellows controlling the tap (6). <IMAGE>
