Abstract
PURPOSE: To prolong a life of packings and remove them easily by screwing from both sides of a pipe, each combination of a plug and a rod to which a zinc packing and others are fit, thereby to execute selfsealing.
CONSTITUTION: After each rod 3, 3' to which a steel packing gland 10, zinc packing 9, rubber packing 8, steel packing 7, zinc packing 6 and guide 5 are fit, is inserted from both ends of a cylindrical body 1, a plug 2 is screwed through. The zinc packing 6 has a smooth face in contact with the rubber packing 8, a spherical face at the back and lip 13 at the rim. The steel packing gland 7 is shaped as fitting to the zinc packing 6. Applied with extremely high pressure from a pressure nozzle 23 of a rod 3, the rubber packing 8 is deformed to seal and blocked by the lip 13. Packings can be served for a long term and readily removed.
