The opening pressure of the safety valves on low-temperature tank trucks specified in several standards does not match the design pressure of these tank trucks; please advise

The last edit to this post was made by Flowers Fill the Western Tower on 2019-4-28 at 21:23. The Safety Inspection Regulations for Mobile Pressure Vessels and the Safety Inspection Regulations for Liquefied Gas Transport Cylinders stipulate that the opening pressure of the safety valves on low-temperature tanks must not be higher than the design pressure of those tanks. However, for low-temperature liquid transport cylinders, it is specified that the opening pressure of the safety valves should be 1.05–1.1 times the design pressure of the cylinder. Isn’t this a contradiction? Why is the opening pressure of the safety valves on low-temperature tanks lower than the design pressure of those tanks?；
