Valve Low Temperature Sealing Test Device Cryogenic Valve
Strict manufacturing technology and special equipment are adopted
for the produced cryogenic valves, and strict quality control is
carried out on the processing of parts. After a special
low-temperature treatment, the rough-machined parts are placed in
the cooling medium for several hours (2-6 hours) to relieve stress,
ensure the low-temperature performance of the material, and ensure
the finished size to prevent the valve from being in
low-temperature conditions. Leakage caused by deformation caused by
temperature changes. The assembly of the valve is also different
from that of the ordinary valve. The parts need to be strictly
cleaned to remove any oil stains to ensure the performance.
Advantage of Valve Low Temperature Equipment
1. It has extreme low temperature ,with the lowest temperature
reaching -196℃,which can greatly meet the requirements of cryogenic
treatment and cryogenic experiments for cryogenic valves and
ultra-low temperature valves.
2. The latest intelligent temperature control system is adopted
,which can set required temperature parameters,cooling speed and
heat preservation time according to process requirements ,and has
process recording and remote monitoring functions.
3. The equipment adopts advanced liquid nitrogen dispersion
technology and unique cold aircirculation system,make full use of
liquid nitrogen function ,and completes the air tightness test of
low-temperature valve in the process of uniform,stable and rapid
Inner cavity dimension
