【Daily Question 2019】LNG Section – Question No. 5-08: How to put a safety valve into operation? The safety valve has passed the calibration test and is installed properly. First, open the hand valve before the safety valve, and then open the hand valve after the safety valve. Ensure that the bypass valve of the safety valve is closed, check that the lead seal on the safety valve is in good condition, and verify that there are no leaks at the flange connections. 3 correct for wealth, 1 incorrect for wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

1) Inform the operator that this safety valve is about to be put into use; first open the valve downstream of the safety valve to check for any leaks at the flange. 2) Slowly open the valve upstream of the safety valve again to locate the leak, and inform the operator that the safety valve is now in use. Seal the valves upstream and downstream of the safety valve with lead seals. 3) Check whether the feeder switch has been fully closed.

How to put a safety valve into operation? Answer: 1. Inform the operator that this safety valve is about to be put into use; first open the valve downstream of the safety valve to check for any leaks at the flange. 2. Slowly open the valve upstream of the safety valve to locate the leak point, and inform the operator that the safety valve is now in use. Seal the valves upstream and downstream of the safety valve with lead seals. Precautions: 1. The upstream manual valve must be closed before cutting off the flow, followed by closing the downstream manual valve; the reverse order is applied when restarting operation. 2. The bypass valve of the safety valve must not be opened under normal operating conditions. 3. The upstream and downstream valves must be fully opened to ensure the safe operation of the equipment.
