摘要： PURPOSE: To keep the pressure in a pipe over the saturated pressure of liquefied gas by controlling the flow rate of the liquefied gas which flows in the pipe.
CONSTITUTION: A return valve 13 is installed in parallel to a receiving operating valve 7 at the base of a storage tank, and a pressure detector 14 is installed onto the upstream side of the return valve 13. The return valve 13 is controlled in correspondence with the output of the pressure detector 14. In the above- described control, the saturated vapor pressure PA of the liquefied gas which corresponds to the liquid temperature TA in a pipe is obtained, and the flow rate V of the liquefied gas is controlled so that the pressure in the pipe is kept at the pressure PC higher than the saturated vapor pressure PA, and the pressure in the pipe can be kept over the saturated vapor pressure of the liquefied gas.

摘要： PURPOSE:To keep the pressure in a pipe over a prescribed value by controlling a receiving operating valve in correspondence with the outputs of the pressure transmitters installed into the receiving pipe, when liquefied gas is received. CONSTITUTION:The unloading arm for the first receiving pipe 5 and pressure transmitters 13 and 14 on the downstream side of the unloading arm are arranged for the second receiving pipes 5 and 6 connected to the unloading arms 1 and 2 through receiving valves 3 and 4. The pressure in the pipe on the upstream side of a receiving operating valve 17 is kept over the saturated vapor pressure of liquefied gas by controlling the receiving operating valve 17 corresponding with the outputs of the both pressure transmitters 13 and 14. With such constitution, the trouble of gasification of the liquefied gas on receiving can be prevented.
摘要翻译：目的：通过控制与安装在接收管中的压力变送器的输出相对应的接收操作阀，当接收到液化气时，将管道中的压力保持在规定值以上。构成：用于第一接收管5的卸载臂和卸载臂下游侧的压力变送器13和14被布置成用于通过接收阀3和4连接到卸载臂1和2的第二接收管5和6。通过控制与两个压力变送器13和14的输出对应的接收操作阀17，在接收操作阀17的上游侧的管中的压力保持在液化气体的饱和蒸气压之上。通过这样的结构，可以防止液化气体在接收时气化的麻烦。

摘要： PURPOSE:To smooth the receiving of liquefied gas and stop by the automatic control of a receiving valve by the signals supplied from the receiving valve, differential-pressure transmitter, flow meter, etc. which are input into a receiving and coldness preservative circulation control part. CONSTITUTION:A plurality of storage tanks including a coldness preservation type circulation tank 11 connected to either of receiving pipes 5 and 6 are installed, and a basic valve 17 is installed at the base of each tank. A selector valve 19 for switching the receiving and coldness preservative circulation is installed into the receiving pipe 6, and a coldness preservation type circulation pump 12 is installed onto the upstream side of the selector valve 19. Further, the coldness preservation type circulation pump 12, basic valve 17, selector valve 19, etc. are controlled with the parameters such as each pressure and the flow rate in the receiving pipes 5 and 6. With such constitution, the receiving of liquefied gas and stop can be carried-out smoothly.
