This paper discusses the relationship between the position of cut-off and the control pressure on the shear-type safety valve. Based on the difference between the actual distance and the calculated value of each hole in the product and the center of the shaft, the author analyzes the influencing factors in the operation of this type of safety valve, and puts forward concrete opinions on the strength of the shears and the material selection.
