The working process of the invention is as follows: when the temperature of the liquid reaches the freezing critical temperature, the liquid level of the expansion liquid in the ball body under the double-ball cup is lowered due to the effect of temperature conduction, the piston is pushed to move downwards together with the pushing rod under the effect of the conical spring, and meanwhile the mounting column also moves downwards, at the moment, the lower conducting ring is contacted with the lower conducting arm, the first relay is attracted, the normally open contact of the first relay is closed, and the liquid pump is started to enable the liquid to flow through the backflow pipe; if the temperature of the liquid continuously drops, the liquid level of the expansion liquid in the lower ball body further drops, the piston is pushed to further drop together with the pushing rod, the mounting column further drops, at the moment, the upper conducting ring is contacted with the upper conducting arm, the second relay is attracted, the normally open contact of the second relay is closed, and the electric heater heats the liquid in the liquid storage tank on the premise that the liquid pump continuously works; when the temperature of the liquid rises, the liquid level of the expansion liquid rises, the expansion liquid pushes the piston to move upwards due to the blocking effect of the one-way valve so as to drive the push rod to move upwards, the upper conducting ring on the mounting column is separated from the upper conducting arm, the second relay is released, the normally open contact of the second relay is disconnected, the electric heater stops heating, and the liquid pump continues to work; if the temperature of the liquid continuously rises, the liquid level of the expansion liquid in the lower ball body enables the pushing piston to continuously rise, at the moment, the lower conducting ring is separated from the lower conducting arm, the first relay is released, the normally open contact of the first relay is disconnected, and the liquid pump stops working; if the temperature of the liquid continuously rises above the set value, along with the upward movement of the pushing piston, the pushing piston enters the upper sphere in the double-sphere cup, and the expansion liquid flows into the upper sphere of the double-sphere cup from the periphery of the pushing piston, so that the expansion of the expansion liquid is prevented from damaging the expansion liquid type temperature controller, and after the lower sphere falls, the expansion liquid remained in the upper sphere flows back into the lower sphere through the one-way valve. The contact stroke of the upper conductive ring and the upper conductive arm can be changed by adjusting the upper adjusting screw, and the contact stroke of the lower conductive ring and the lower conductive arm can be changed by adjusting the lower adjusting screw.
