Abstract

PURPOSE: To inject exact amount of specific by means that pressure switches are provided to detect any leakage of it from opening-and-closing valves.
CONSTITUTION: The primary and the secondary pressure switches 11, 12 are provided in the line of a pipe 6 on the way to a pump 5, which is branched into branch pipes 7, 8 where opening-and-closing valves 9, 10 are supplied. With the opening- and-closing valves 9, 10 closed, the pump 5 is started and a pressure in the pipe 6 rises to a specific value so that the primary pressure switch 11 is turned on to open the opening-and-closing valve 9. When the primary and the secondary pressure switch 11, 12 are turned off and on independantly to inject the specific from a specific tank 3 into a boiler 1, any leakage prevents the pressure in the pipe 8 from rising up to a specific value under the condition the opening-and-closing valves 9, 10 are closed. Warning is developed due to the locked-off primary pressure switch 11 so that the specific may by prevented from injecting excessively
