Gas formed in the evaporator through a regulator, the counter, the
valve of blocking of gas and air arrives to a furnace torch. Thermal loading of
a torch of the furnace changes by means of the adjusting gate before a torch.
At increase in thermal loading of the furnace more intensive selection of gas
from the evaporator begins, thus pressure in the evaporator starts to fall. Ringtones: Download absolutely free sprint ringtones for cell phone . Take pleasure in popular cartoons online. . Absolutely free download cingular ringtones for cell phones.
In the tank pressure thus does not change (pressure in the tank depends
only on temperature of external air), and therefore there is a difference of pressure,
the liquid in the evaporator will arrive more intensively and its level in the
evaporator will raise. With increase in a surface of evaporation the quantity
of gas will increase, and its pressure will rise to establishments of former balance.
 At even
большем increase in the expense liquid level in the evaporator will continue to
rise, thus there can be a danger of overflow of the evaporator and penetration
of a liquid phase into a regulator and a torch. It can occur also at extinction
of a torch of the evaporator.
For prevention of overflow of the evaporator
it is established a maximum level regulator.
At increase of level of a liquid in the evaporator to maximum the float
which is in the chamber, rises in extreme top position, the valve closes an aperture
and stops liquid receipt through the regulator chamber in the evaporator.
At
reduction of the expense of gas in the evaporator pressure will raise. For prevention
of it the return valve which opens at pressure increase in the evaporator on 1
kg/sm2 in comparison with pressure in the tank is established. Having opened,
the valve перепускает a liquid phase from the evaporator in the tank. Thus the
evaporation surface decreases and again balance is established.
