Gas Relief Valve Design for Low Temperature.
DEPARTMENT OF THE AIR FORCE WASHINGTON DC
Pagination or Media Count:
A relief valve is provided with slots across the end of the valve stem where contact is made with the valve body to eliminate gas pressurization in the annular area bounded by circumferential contact between the valve stem and the body and a smaller diameter circumferential contact between valve seatseal members. This construction prevents any leakage gas from becoming trapped between the valve stem and the container which would lower the design cracking pressure thereby adversely affecting the operation of the relief valve.
