Title: Fluid loading control device
Inventor: SHIMADA KOJI
IPC: B67D7/28
Filed: 1990-09-21
Abstract: PURPOSE:To shorten loading time by a method wherein an initial speed limit quantity is made changeable in response to the hatch capacity, etc., of a movable tank vehicle. CONSTITUTION:A shipping set value, initial speed limit value and final speed limit value are given from an LSM 7. The LSM 7 and an LSC 6 is connected by an interface such as an RS-232-C, etc., and for the initial speed limit value, data such as, 90l when the shipping set value is 1kl, or respectively 120l, 150l when the shipping set value is 2kl, 4kl, are given in response to the shipping set value. When the shipping set quantity is set in a setting unit 10, the LSC 6 reads this, and reads an initial speed limit quantity which corresponds with this from a memory 63, and performs process after that. The LSC 6 counts flow rate pulse from a flow rate transmitter 3, and when it has counted up to the loading set quantity, the LSC 6 outputs a valve closing signal, and stops shipping of oil. Since the initial speed limit quantity is changed in response to the shipping set quantity, a most suitable control becomes possible, and loading time for the fluid can be shortened.

CONSTITUTION:A wire spring 6 is installed in a hollow portion 5 of a nut 4. The wire spring 6 is formed with a small circular portion 14 at its central portion and with a pair of arcuate press contact portions 8, 8. When the nut 4 is fit to a bolt 3 to tighten scissor blades 1, 2, the press contact portions 8, 8 of the wire spring press a thread portion 7 from both sides.
