Thermostat to control the coolant flow path of the valve. Is a thermostat device, usually containing the temperature component, through expansion or shrinkage to open, turn off the air, gas or liquid flow.
The function of the thermostat
According to the level of the cooling water temperature automatically adjust the amount of water into the radiator, change the scope of the water cycle, to adjust the cooling capacity cooling system to ensure that the engine at the right temperature range. Thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. If the main valve to open the thermostat too late, it will cause engine overheating; the main valve to open prematurely, then the engine warm-up time extended so that the engine temperature is too low.
Thermostat of the structure and working principle
The main use for the wax-type thermostat thermostat, when the cooling temperature is lower than the specified value, the thermostat temperature solid state body refined paraffin wax, the thermostat valve is closed under the action of the spring between the engine and radiator channel by the pump to return the engine coolant, the engine in small cycles. When the coolant temperature reaches the specified value, the wax starts to melt gradually into the liquid, the volume is even greater and the oppression of rubber tubing to shrink. Contraction in the rubber tube at the same time putting the role of the upward thrust, push down on the valve with anti-thrust to open the valve. Then the coolant through the radiator and the thermostat valve, and then the pump flow back into the engine, the big circle.
Wax-type thermostat thermostat works most of the layout of the cylinder head outlet pipe road, so the advantage of simple structure, easy to eliminate air bubbles in the cooling system; disadvantage is that the thermostat is always at work, opening and closing, resulting in oscillation.
