СПОСОБ ПРОВЕРКИ ГЕРМЕТИЧНОСТИ ЗАМКНУТЫХ ОБЪЕМОВ

摘要

FIELD: the invention refers to the field of controlling-measuring technique and may be used in cosmic technique namely at checking insulation of sections of pipelines of pneumatic hydraulic systems in conditions of essential changing of temperature. ^ SUBSTANCE: the mode includes creation in a checked closed volume V of prescribed pressure of gas, measurement of pressure at the beginning Pp and at the end Pe of the given time interval te. At that simultaneously with definition of initial pressure Pp initial temperature of gas Tp is measured. Temperature Te is measured at the end of preset time interval taue at the same time as gas pressure Pe. Summary mass leakage of gas Ge is defined and in case of fulfillment of ratio Ge
