Abstract
The utility model discloses a sealing washer which comprises a silica gel ring, the cross section of the silica gel ring is trapezoid, the middle of the outer wall of the silica gel ring and the middle of the inner wall of the silica gel ring are respectively provided with one annular protrusion, the cross section of each annular protrusion is rectangular, and a hard alloy ring is installed inside the silica gel ring. Compared with an existing washer, the sealing washer has the rectangular cross section and can be tightly attached to a flaring of a pipe. Besides, the middle of the outer wall of the silica gel ring and the middle of the inner wall of the silica gel ring are respectively provided with one annular protrusion, the cross section of each annular protrusion is rectangular, and the annular protrusions can be in sealing connection with the end face of the flaring of the pipe, so that sealing performance is greatly enhanced. The hard alloy ring is installed inside the silica gel ring to strengthen hardness of the silica gel ring.
Description
Technical field
The utility model relates to a kind of packing ring, relates in particular to a kind of seal washer.
Background technique
The PVC＝polyvinyl chloride pipes for mining mostly adopts flanged joint connection, straight socket joint to connect and the connection of R socket joint at present, seal washer all plays an important role in various connections, existing seal washer sealing effect is poor, often occur under its rugged environment, joint socket breaks, the squeezed phenomenon such as take off of seal washer.
The model utility content
For the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of seal washer that solves above problem.
The technical solution of the utility model is: a kind of seal washer, comprise silica gel ring, described silica gel ring cross section is trapezoidal, and described silica gel ring outer wall middle part and inwall middle part all are provided with ring shape projection, described annular protrusion cross section is rectangle, is provided with carbide ring in the described silica gel ring.
As preferably, the diameter of described carbide ring cross section is identical with the thickness of annular protrusion.
As preferably, described silica gel ring and annular protrusion are one-body molded.
