用于推进剂贮箱的叉形环
摘要：
本实用新型提供一种用于推进剂贮箱的叉形环，叉形环具有经整体淬火处理形成的淬火层。本实用新型经淬火强化的叉形环具有经整体淬火处理形成的淬火层，加强了自身强度，克服了传统设计中退火态的叉形环不能满足大的使用载荷的技术缺陷。
摘要（英）：

The utility model provides a fork ring for a propellant storage tank. The fork ring comprises a quenched layer which is wholly treated with quenching. The fork ring, which is enhanced through quenching and comprises the quenched layer, is higher in intensity, and overcomes the technical defect that the conventional fork ring in an annealing state cannot meet the requirement of large use load.
