Abstract
The invention discloses a metal sleeve for shaped packing sealing. The metal sleeve comprises a metal sleeve main body, a rubber ring, a packing groove, a packing layer, a feeding hole and a discharging hole, wherein the metal sleeve main body, the packing groove, the feeding hole and the discharging hole are integrally formed, the feeding hole is formed in the left side of the metal sleeve main body, the discharging hole is formed in the right side of the metal sleeve main body, the packing groove is formed in the inner side of the metal sleeve main body, the rubber ring is attached to the inside of the packing groove, and the packing layer is machined on the surface layer of the rubber ring. By virtue of the mode, the metal sleeve for the shaped packing sealing provided by the invention is high in match and installation precision and strong in working temperature adaptability and has a packing sealing effect.
Description
Technical field
The present invention relates to mechanical Component field, particularly relate to a kind of shaped packing seal metallic sheath.
Background technique
Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.Its Performance Influence Factor of various sealings is different, temperature is arranged, medium, wearing and tearing, the pressure etc. that bears as influence factors such as mechanical seal packing seals.The only Packed function of general Sealing does not have other characteristic, so wishes to produce a kind of Sealing of energy filler.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of shaped packing seal metallic sheath, cooperates the installation precision height, and is strong to operating temperature adaptability, has the gland sealed effect.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of shaped packing seal metallic sheath is provided, comprise: metallic sheath main body, rubber ring, packing groove, packing layer, material feeding mouth and discharge port, described metallic sheath main body, packing groove, material feeding mouth and discharge port are one-body molded, described material feeding mouth is opened the left side in the metallic sheath main body, described discharge port is opened the right side in the metallic sheath main body, described metallic sheath main body inboard has packing groove, rubber ring is posted in described packing groove inside, and described rubber ring top layer is processed with packing layer.
In a preferred embodiment of the present invention, described packing groove inside is provided with filter screen.
In a preferred embodiment of the present invention, described rubber ring is made by butyronitrile.
In a preferred embodiment of the present invention, described metallic sheath main body is made by cast iron.
The invention has the beneficial effects as follows: a kind of shaped packing seal metallic sheath of the present invention, cooperate the installation precision height, strong to operating temperature adaptability, have the gland sealed effect.
Description of drawings
