METHOD FOR SUPPRESSION OF GAS LEAKAGE THROUGH VALVE COLUMNS

摘要

A method for suppression of gas leakage through valve columns that has plug and drive shank through supply of sealing material to cavity of the valve from individual source through horizontal channel. Sealing material is supplied to cavity between the plug and drive shank, and source of supply of sealing material is permanently connected to horizontal channel, at that pressure of sealing material supply is determined in experimental way.
