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.

2. Description of the Related Art Conventionally, as a chemical liquid storage facility of this type,
A liquid reservoir provided to allow the leakage of the chemical liquid that has leaked from the chemical liquid storage tank, an opening / closing valve provided in a transfer pipe extending from the liquid reservoir to a predetermined location, and a contact with the chemical liquid flowing into the liquid reservoir. It is composed of a sensor such as a PH meter or an electric conductivity meter for distinguishing rainwater from chemicals and a control means for opening and closing the valve based on the output signal of the sensor. When the sensor determines rainwater, the valve opens. It is known that rainwater is discharged from the liquid pool due to the leakage, and when the sensor determines that it is a chemical liquid, the valve is closed to prevent the chemical liquid in the liquid pool from flowing out.
