Principle Of Cryogenic Globe Valve
Low temperature flange globe valve can be divided into long axis
and short axis. It is suitable for the management system of
cryogenic liquid storage and transportation equipment. It has the
characteristics of flexible switch and reliable sealing. It can
also be used for other cryogenic and cryogenic medium management
systems. The material of the extended rod low temperature globe
valve to work at low temperature should ensure its low temperature
performance, mainly to ensure its cold impact strength. The
internal parts of low-temperature valves must be properly selected
so that they have sufficient cold impact strength to prevent
fracture. The alloy steel of C and Cr quickly loses its impact
strength when it is below -20℃, so the service temperature is
limited to -30℃ and -50℃, respectively. Nickel steel with a Ni
content of 3.5% can be used up to -100°C, and nickel steel with a
Ni content of 9% can be used up to -196°C.
Advantages Of Cryogenic Globe Valve
1. The structure of the globe valve is simpler than the gate valve,
and it is more convenient to manufacture and maintain. 2. The
sealing surface is not easy to be worn and scratched, and the
sealing is good. There is no relative sliding between the valve
flap and the sealing surface of the valve body when opening and
closing, so the wear and scratch are not serious, the sealing
performance is good, and the service life is long. 3. When opening
and closing, the flap travel is small, so the height of the cut-off
valve is smaller than that of the gate valve, but the structural
length is longer than the gate valve.
Installation and maintenanceThe installation and maintenance of the
high-pressure globe valve should pay attention to the following
matters:The shut-off valve operated by hand wheel and handle can be
installed at any position of the pipeline.Handwheels, handles and
moving mechanisms are not allowed for lifting.The flow direction of
the medium should be consistent with the arrow direction shown in
the valve body.
