1.Product descriptionDewar, also called thermos, is an ideal
container and tool for storing liquid gas, low temperature research
and crystal element protection.2.FUNCTIONThe main structure and
functions of each part of Dewars are as follows:1.Outer cylinder:
In addition to protecting the inner cylinder, it also forms a
vacuum interlayer with the inner cylinder to prevent the intrusion
of heat from outside the bottle and reduce the natural vaporization
of cryogenic liquid in the bottle;2.Inner cylinder: store cryogenic
liquid;3. Vaporizer: Through heat exchange with the inner wall of
the outer barrel, it can convert the liquid gas in the bottle into
a gaseous state;4. Liquid valve: Control the Dewar to fill or
discharge liquid from the bottle;5.Safety valve: When the pressure
of the vessel is greater than the maximum working pressure, it will
automatically relieve the pressure, and its take-off pressure will
be slightly greater than the maximum working pressure;6.Drain
valve: When the Dewar is filled with liquid, use this valve to
discharge the gas in the gas phase space in the bottle, reduce the
pressure in the bottle, so as to fill the liquid quickly and
smoothly. Another function is that when the pressure in the Dewar
bottle exceeds the maximum working pressure during storage or other
conditions, this valve can be used to manually discharge the gas in
the bottle to reduce the pressure in the bottle;7. Pressure gauge:
Indicate the pressure of the inner cylinder of the bottle;8.
Boosting valve: After this valve is opened, the liquid in the
bottle will exchange heat with the outer cylinder wall through the
booster coil, vaporize into gas, enter the gas phase space on the
upper part of the inner cylinder wall, and make the cylinder build
up a certain driving pressure (Internal pressure) in order to drive
the cryogenic liquid in the bottle to make it flow;9. Use valve: It
is used to open the pipeline passage between the liquid
vaporization circuit of the Dewar flask and the gas inlet end of
the user. This valve can also be used to control the flow rate of
the gas;10. Liquid level gauge: It can indicate the height of the
liquid level in the container more intuitively, and the
installation position should be convenient for the operator to
observe and repair.3.SAFETYDewar flasks generally have 4 valves,
namely, liquid use valve, gas use valve, vent valve, and booster
valve. In addition, there are gas pressure gauges and level gauges.
The Dewar flask is not only equipped with a safety valve, but also
with a rupture disc . Once the pressure of the gas in the bottle
exceeds the take-off pressure of the safety valve, the safety valve
will immediately take off and automatically discharge the pressure.
If the safety valve fails or the gas cylinder is accidentally
caused to destroy the vacuum layer, the pressure in the cylinder
rises sharply to a certain level, and the rupture disk is
automatically ruptured, so that the pressure in the cylinder can be
quickly reduced to atmospheric pressure in time . The Dewar bottle
stores medical liquid oxygen, which greatly increases the oxygen
storage capacity. A Dewar with a volume of 175 L has an oxygen
storage capacity equivalent to that of 28 high-pressure gas
cylinders with a volume of 40 L, which greatly reduces
transportation pressure and reduces capital investment. There are 2
ways to use Dewar flasks:(1) Dewar gas use valve, connect one end
of the high-pressure metal hose to the Dewar gas use valve, and the
other end to the busbar. First open the increase valve, and then
slowly open the gas use valve, you can use it. Most hospitals only
use gas phase valves to meet gas demand.(2) Dewar liquid valve, use
a high-pressure metal hose to connect the pipe where the Dewar
liquid valve is located with the vaporizer. The size of the
vaporizer is configured according to the amount of gas used. The
seamless steel pipe is used to transport the gas. The installation
on the pipeline is reduced. Pressure valves, safety valves, and
pressure gauges are used to control the safety of the gas supply
system, so that the gas can be used conveniently and stably, while
ensuring safe use. When using a Dewar, first confirm the
connection, and then open the liquid use valve. If the gas pressure
does not meet the use requirements, you can open the booster valve,
wait a few minutes, the pressure will rise and meet the use
requirements .4 specifications5.Our Services:We supply high quqlity
