摘要： PROBLEM TO BE SOLVED: To provide a method for safely recovering/restoring a nozzle main-valve in a tank in operation. SOLUTION: This method comprises the following steps: in the first step, the main-valve B of the nozzle A is closed, and a connection bolt C of the nozzle A and the main-valve B is replaced by a temporarily tightening jig 1. In the 2nd step, the valve B is held by a main-valve holding jig 4 penetrated in a chamber 2, an expandable sealing stop 6 is attached to a sealing-stop guiding jig 7 penetrated in the chamber 2, then the chamber 2 is airtightly attached to the nozzle A. In the 3rd step, the temporarily tightening jig 1 is separated by a separating jig 3 penetrated in the chamber 2, and the main-valve holding jig 4 is drawn up to remove the valve 3 from the nozzle A. In the 4th step, the stop 6 is guided by the jig 7 to be fit to the opening of the nozzle A. In the 5th step, the stop 6 is expanded by a stop-expanding jig 8 penetrated in the chamber 2 and the opening of the nozzle A is closed. In the 6th step, the chamber 2 is removed, the jig 7 is separated from the stop 6, and the main valve B is recovered. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent a lead pipe from vibrating while LNG is being received via a bottom feed line in an LNG underground tank. SOLUTION: The length L of a straight portion 7 forward of an elbow portion 6 formed on a tip side of a feed pipe 5 is set to be at least five times the diameter D of the feed pipe 5. The turbulence generated in passing of the elbow portion 6 is converged in the straight portion 7, the flow speed is unified, and the LNG flows down from a funnel portion 10 into the lead pipe 9. Thus, the quantity of BOG included from the periphery at the funnel portion 10 becomes uniform, and no slag flow is generated in the lead pipe 9. As a result, the vibration of the lead pipe 9 caused by the slag flow is eliminated, and generation of the fatigue at a fitting portion, etc., of the lead pipe 9 can be prevented.
