故障 Explanation: http://www.flowserve.com/vgnfiles/Files/Literature/ProductLi... A three-way switching valve and two pilot-operated three-way lock-up valves are used in the fail-in-place lock-up system. In this system, the positioner operates as a four-way positioner, supplying air to both sides of the actuator piston. The three-way switching valve senses supply line pressure. If supply pressure drops below a preset level, pilot pressure from the three-way switching valve to the lock-up valves is released, causing the lock-up valves to trip and lock the existing air pressure on both sides of the piston. Exhaust ports on the lock-up valves should be plugged. (Figure 5 shows a schematic depicting a fail-in-place lock-up system.) Open = normally open常开,Close = normally close常闭,In-place = Fail-in-place发生故障 |

在原位 Explanation: http://en.termwiki.com/EN/fail-in-place fail-in-place A term used to describe the ability of an actuator to stay at the same percent of travel it was in when it lost its air supply. On SPRING RETURN actuators this is accomplished by means of a lock-up valve. On piston actuators a series of compressed air cylinders must be employed. |

见下 Explanation: Here is the full explanation for fail open, fail closed, and fail in-place: http://www.piping-designer.com/index.php/disciplines/electri... Not sure how to translate into Chinese though. -------------------------------------------------- Note added at 15 hrs (2016-06-13 17:46:37 GMT) -------------------------------------------------- Fail open: 信号中断时安全阀开启 Fail closed: 信号中断时安全阀关闭 Fail in-place: 信号中断时安全阀保持原位(不干预) |
