Title:
EQUIPMENT FOR STORAGE OF LIQUID CHEMICAL
Document Type and Number:
Japanese Patent JP2779878
Kind Code:
B2
Abstract:
PURPOSE: To make the part for the electrical instrumentation unnecessary in the work of installation for the functioning system of a sensor member which is put in contact with a liquid chemical so that the cost of the equipment can be lowered.
CONSTITUTION: A liquid receptacle 13 is provided as a means of holding a pool of liquid chemical which has leaked out of a liquid chemical storage tank 12 and as a means into which such liquid chemical is made to flow. A valve 16 for the opening and closing is provided in a transferring line 15 which extends from the liquid receptacle 13 to a specific place. A force pressing the valve 16 either toward the opening or toward the closure is applied thereto by a pressing means 31. Counteracting this force from the pressing means 31, a holding means holds the valve 16 either in the closed state or in the open state. This holding means has a sensor member 33 which is so placed as to be put in contact with the liquid chemical when it flows into the liquid receptacle 13 and designed to be dissolved upon contact therewith. The dissolution of the sensor member 33 causes a break in the channel for transmitting the action of the holding means to the pressing means 31.
