Applicable Medium For Customize Pressure Cryogenic Ball Valve
Low temperature ball valve is suitable for low temperature medium
such as methane, liquid natural gas, hexene, carbon dioxide, liquid
ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and so on.
Description Of Customize Pressure Cryogenic Ball Valve
The cryogenic ball valve undergoes special low-temperature
treatment, and the rough-machined parts are placed in the cooling
medium for several hours (2-8 hours) to release the stress, ensure
the low-temperature performance of the material, and ensure the
precision processing size, to prevent the valve from operating
under low temperature conditions , Leakage due to deformation
caused by temperature changes. For medium temperature higher than
-50℃, long neck structure is generally not used; for ball valves
with medium temperature lower than -50℃, the neck length is
generally 250mm, or determined according to our company's design
and calculation. It is mainly used to output liquid low-temperature
media such as ethylene, liquid oxygen, liquid hydrogen, liquefied
natural gas, liquefied petroleum products, etc. It is one of the
indispensable important equipment in the petrochemical industry,
air separation, natural gas and other industries. Its quality
determines the quality Whether it is produced safely, economically
and continuously.
Feature Of Customize Pressure Cryogenic Ball Valve
1. The structure of opening a pressure relief hole in the valve
core is adopted.
2. The gasket is made of ceramic filling material with stable
sealing performance.
3. The valve body is light and small in size. In order to reduce
the heat loss of the valve body, especially in order to ensure the
use of the valve at ultra-low temperature, the valve body is
specially designed to be light in weight and small in size.
4. The long shaft valve has a valve through which a low-temperature
fluid flows, and adopts the form of a long valve stem, which can
avoid the external heat and keep the gland at normal temperature to
prevent the performance of the cover seal from degrading. This
length is the best length obtained through calculation and
experiment.
Through the low temperature performance test, to ensure the low
temperature performance of the material and the comprehensive
mechanical properties of the workpiece,Technical characteristics
Strength and rigidity
The stem has an elongated structure and the design includes a
self-adjusting elongated system to compensate for the heat
Wear, tightening and expansion due to change
It has a structure to prevent abnormal pressure increase, and a
pressure relief hole is provided to release the liquid trapped in
the valve cavity
Overpressure caused by medium heating
Frequent operation under low temperature conditions, its internal
materials are not jammed, scratched, etc.
FAQ
Q: Are you trading company or manufacturer ?
