Abstract

Throttle valve is the key equipment of ultra-high pressure natural gas well, and the research on the structure and performance of the throttle valve is particularly important. Among them, the cage-type throttle valve has been studied more and more in recent years because of its many advantages. This article mainly studies the cage of the cage type throttle valve, and makes an in-depth analysis of its structure on the basis of theoretical calculations. Corresponding models are established through the wired element analysis software, and the opening positions of the valve core cage, the opening degree of the cage and the flow area change rule, the number of cage holes and the diameter of the cage are discussed. Studies have shown that when the number of small holes in the valve core cage is fixed, the flow area of the cage increases, the flow velocity in the small holes increases, and the static pressure decreases; when the flow area of the cage is fixed, the number and diameter of the throttle holes are changed, The flow rate of the flow valve is basically unchanged. It is recommended to change the diameter of the small hole and the flow area under the condition that the structure of the valve core cage is determined, and the throttling effect will be more significant.
