| Abstract: | Adjustment spring is the key part of cryogenic safety valve,it take a important role of the valve′s function.For assuring the precision of valve,the designed size of adjustment spring overrun the standard range and the nonstandard spring is disbenefit for producing.Thus the combined spring structure is utilized to reduce the wire diameter in the improvement designing of rocket valve.The disadvantage and advantage is also contrasted between the two structures in the thesis. |
