锻焊结构阀体的闸阀和其它阀体结构的闸阀相比,优点是最易于制造,所以在化工设备的管路系统中用得越来越广。通常,闸阀锻焊阀体的结构很复杂,使它的强度难于计算,但由于这种闸阀的使用经验不多,因此研究它的应力状态是迫切的任务。 Forged welded valve body valve gate valve body structure and compared to the other, the advantage is the most easy to manufacture, so in the pipeline system of chemical equipment used more and more widely. In general, the structure of the forged valve body of the gate valve is very complicated, making it difficult to calculate its strength. However, due to the lack of experience in using such a gate valve, studying its stress state is an urgent task.
