高压加氢装置中使用的高压闸阀，基本用于紧急切断和紧急放空，对产品性能有很高的要求，分为两种结构，即传统的楔形闸阀和平行闸阀。描述了如何在加氢装置中的高温高压工况下选择合适的闸阀；主要介绍了各种闸阀的结构特点和适用范围，从而得出了新结构的高压平行闸阀更加适合在加氢装置中紧急切断和放空场合下适用。
高壓加氫裝置中使用的高壓閘閥，基本用于緊急切斷和緊急放空，對產品性能有很高的要求，分為兩種結構，即傳統的楔形閘閥和平行閘閥。描述瞭如何在加氫裝置中的高溫高壓工況下選擇閤適的閘閥；主要介紹瞭各種閘閥的結構特點和適用範圍，從而得齣瞭新結構的高壓平行閘閥更加適閤在加氫裝置中緊急切斷和放空場閤下適用。

High pressure gate valve used in high pressure hydrogenation unit is basically used for cut-off and emergency venting, showing very high requirements for product performance. The gate valve has two structures, typical wedge gate valve and parallel gate valve. How to select proper gate valve under the working condition with high pressure and high temperature is described. Structural characteristics and applicable ranges of all types of gate valves are mainly introduced. Therefore, high pressure gate valve with new structure is more proper for application in emergency cut-off and emer encv ventine in the hydrogenation unit.
