阀杆密封的设计
阀杆和阀体的密封分高温 G 型和低温 P 型两种，<200℃时使用 V 型 PTFE 环作为阀杆的填料，V 型 PTFE 可以减少较大温差变化造成的外漏；≥200℃时使用石墨环和高碳盘根作为阀杆的填料并配以碟簧承载，以保证长期密封。
Design of Valve Stem Seal
The sealing between valve stem and valve body comes in two types: high-temperature G-type and low-temperature P-type. If the temperature is <200 ° C, V-type PTFE rings are used as the stem packing to reduce the external leakage caused by signifi cant temperature diff erences. If the temperature is ≥200° C, graphite rings and high-carbon stem packing are used, along with disc springs for support, to ensure the long-term sealing.
