2.6.1. Check of a cover of a broad tank
Fig. 2.28. An arrangement of the vacuum valve (2) and the valve of pressure (3) in a cover of a broad tank (1)
The cover 1 (fig. 2.28
) a broad tank has the vacuum valve 2 and the valve of pressure 3. The cover supports necessary pressure in cooling system.
Wash up a cover of a broad tank and clear of a dirt a saddle of the vacuum valve.
Check up the vacuum valve of a cover of a broad tank on absence of damages and deformation. In the presence of damages replace a cover.
Establish a cover on the device for pressure check in cooling system. Create depression and check up work of the vacuum valve.
Create pressure 90—120 кПа and through 10 with check up the pressure shown by the device. If pressure more low 80 кПа, replace a cover of a broad tank.
