Abstract

PURPOSE: To get confirmation lightly through daily inspection, on whether steam extracting non-return electro-magnetic valve fulfil its function normally or not, by additionally providing testing electro-magnetic valve and pressure detector.
CONSTITUTION: Fully close testing electro-magnetic valve 7 and enclose pressed air for opening of extracting non-return valve 4. Choosing a time for complete ending of whole closing action of testing electro-magnetic valve 7, let operate extracting non- return electro-magnetic valve 6 for extraction. When this performance is performed normally, the air enclosed between extracting non-return electro-magnetic valve 6 and testing electro-magnetic valve 7, is extracted and pressure detector 8 detect pressure drop and let indicate by means of indicating lamp etc. whether extracting non-return electro-magnetic valve 6 performed extracting performance and finish thus performance test.
