3.13.6. The thermostatThe thermostat
1 – an entrance branch pipe (from the engine);
2 – перепускной the valve;
3 – a spring перепускного the valve;
4 – a glass;
5 – a rubber insert;
6 – a target branch pipe;
7 – a spring of the basic valve;
8 – a saddle of the basic valve;
9 – the basic valve; |
10 – the holder;
11 – an adjusting nut;
12 – the piston;
13 – an entrance branch pipe from a radiator;
14 – наполнитель;
15 – a holder;
D – an input of a liquid from the engine;
Р – an input of a liquid from a radiator;
Н – a liquid exit to the pump |
At the thermostat it is necessary to check temperature of the beginning of opening of the basic valve and a course of the basic valve.
For this purpose the thermostat establish at stand BS-106-000, having lowered in a tank with water or a cooling liquid. From below against the basic valve 9 rest an arm of a leg of the indicator.
The liquid reference temperature in a tank should be 73–75 ° S.Temperaturu of a liquid gradually increase approximately on 1 ° With in a minute at constant hashing that it in all volume of a liquid was identical.
That at which the course of the basic valve will make 0,1 mm is accepted to temperature of the beginning of opening of the valve.
It is necessary to replace the thermostat, if the temperature of the beginning of opening of the basic valve is not in limits 81 5-4 ° With or a valve stroke less than 6,0 mm.
The elementary check of the thermostat can be carried out to the touch directly on the car. After start of the cold engine at the serviceable thermostat the bottom tank of a radiator should heat up, when the arrow of the index of temperature of a liquid is approximately on distance of 3-4 mm from a red zone of a scale that corresponds 80–85 ° With.
