Background technology
Thermostat is also referred to as thermosistor, is a kind of automatic temperature-regulator, can be according to the height of coolant temperature containing the temperature module
The open and-shut mode of low automatic change valve, so as to change the circulating path of engine coolant and enter the cooling liquid stream of radiator
Amount, to adjust the heat-sinking capability of cooling system, ensures that engine works within the scope of suitable temperature.
The thermostat used at present is mainly waxtype thermostat, its control principle is expanding with heat and contract with cold for temperature sensor internal paraffin
Principle.When coolant temperature is less than setting, the exquisite paraffin in temperature sensor is in solid-state, and thermostat main valve is in main spring
The lower passage between closing engine and radiator of effect, coolant carry out partial circulating in engine through water pump return engine
(referring to Fig. 5).After coolant temperature reaches setting, paraffin starts gradually to be melted into liquid, and volume increases and oppresses rubber
Sebific duct makes its contraction, and upward thrust is imposed to push rod while rubber tube is shunk, and push rod then imposes main valve downwards
Propulsive thrust, and overcome main spring resistance main valve is gradually opened, bypath valve progressively closes off.At this moment coolant is via heat dissipation
Device and thermostat valve, then engine is flowed back to through water pump, systemic circulation is carried out, takes away the heat that engine work produces.

5 minutes, make thermostat nature standard-sized sheet, the shortcomings that the method is time-consuming longer, and requires the subsequent operation time to try one's best short could to protect
Card thermostat is in fully open position all the time, is also easy to cause and does over again；3rd, disconnected main spring is clamped with diagonal cutting pliers, then arrive main valve is open-top
The shortcomings that fully open position, the method is that spring hardness is big, and gap is close, operating difficulties；4th, main spring is blown with argon arc welding spot welding, this
Method is current most common method, and advantage is that speed is fast, since arc temperature is high, while spring fuses, since heat passes
Effect is led, thermostat has also reached fully open position, and shortcoming needs extreme care when being operation, otherwise easily scalds, especially careful
Anti- burn-through temperature sensor, triggers paraffin on fire or even explosion is hurted sb.'s feelings, while the method can cause thermostat permanent damage, influence
Secondary normal use.
Step 2: thermostat main valve is maintained in the fully-opened position.
The method for realizing the step is typically to be symmetrically welded two sections of hard wires between stent and by-passing valve, and when spot welding is same
Be careful to operate, to prevent burning temperature sensor, while welding procedure also there are certain requirements, it is ensured that valve face it is smooth, otherwise hold
