What is?
The thermostat valve is controlled coolant flow path. An automatic adjustment device, generally contain temperature-sensitive components, by controlling the valve opening, closing, controlling the flow direction of the liquid.

Function
the thermostat is automatically adjusted according to the level of water into the cooling water temperature of the radiator, circulating water ranges change, to adjust the cooling capacity of the cooling system, to ensure that the engine is operating within a suitable temperature range.

works
thermostat is mainly used for the wax-type thermostat, when when the cooling temperature is lower than a predetermined value, the thermostat temperature sensing body is solid refined paraffin wax, the thermostat valve closes the passage between the engine and the radiator under the action of the spring, the coolant returned to the engine by the pump, an engine for a small cycle. When the coolant temperature reaches a predetermined value, it begins to melt gradually to a liquid paraffin, followed by increasing the volume of the rubber tube and presses the shrunk. While contraction of the rubber tube upward thrust to push rod, the push rod of the valve downward thrust reverser open the valve. In this case the radiator and the coolant through the thermostat valve, and then back into the engine by the pump, a large circulation.
