用于流体阀的故障安全防护装置
摘要：
本实用新型公开了一种用于流体阀的故障安全防护装置。示例故障安全防护装置包括第一活塞，相对于第一活塞可移动地耦接的第二活塞，和在第一和第二活塞之间用于容纳控制流体的流体室。当控制流体被提供在流体室中时该控制流体可操作地耦接第一和第二活塞。当从流体室移去控制流体的至少一些时第一活塞可操作地与第二活塞去耦。
摘要（英）：

The utility model discloses a fault safety protection device used for a fluid valve. The fault safety protection device comprises a first piston, a second piston and a fluid chamber, wherein the second piston can be connected relative to the first piston in a movable and coupling mode, and the fluid chamber is arranged between the first piston and the second piston and is used for containing control fluid. When the control fluid is supplied to the fluid chamber, the control fluid can be connected with the first piston and the second piston in an operable and coupling mode. When at least some of the control fluid is removed out of the fluid chamber, the first piston is connected with the second piston in an operable and coupling mode.
