Claims

[Scope of Claim for Utility Model Registration] (1) A floating seal in which a pair of ring seals with a tapered surface are connected to the sliding surface and are in sliding contact, and the sliding surface of the ring seal is composed of a high-alloy ring. A floating seal is formed by joining a ring seal base material made of inexpensive mild steel or a lower material by baking diffusion or brazing. (2) Form an annular notch by leaving the annular flange at the lower end of the sliding surface of the ring seal base material, and fit a high alloy ring having a sliding surface and a tapered surface connected thereto into the annular notch. , the outer peripheral end of the ring projects slightly outward from the end of the base material,
The floating seal according to claim 1, wherein the tapered surface of the ring and the end surface of the annular flange of the base material are made to coincide with each other to form a part of the tapered surface. (3) An annular notch is provided on a part of the sliding side surface of the ring seal base material, and an annular notch is provided on the back surface of the sliding surface of the high alloy material ring, which has a sliding surface and a tapered surface connected thereto. providing a notch and engaging the annular notch of the base material and the annular notch of the ring;
A request for registration of a utility model, characterized in that the outer circumferential end of the ring protrudes slightly outward from the end of the base material, and the lower part of the tapered surface of the ring protrudes in front of the sliding side surface of the base material. Floating seal as described in item 1. (4) The sliding side surface of the ring seal base material is made into a tapered surface, a high alloy material ring having a sliding surface is joined to the outer peripheral surface of the base material, and the sliding surface and the tapered surface are made into a continuous surface. A floating seal according to claim 1 of the utility model registration claim, characterized in that: (5) A high-alloy ring having a tapered surface and connected to the sliding surface is joined to the upper part of the sliding surface of the ring seal base material so that the ring slightly protrudes outward from the base material. A floating seal according to claim 1 of the utility model registration claim. (6) An annular notch is provided in the upper part of the sliding side surface of the ring seal base material, the lower part thereof is a tapered surface, and a cylindrical high alloy material ring having a sliding surface is fitted into the annular notch and slides. Utility model registration claim 1 characterized in that the surface and the tapered surface are continuous surfaces.
Floating seal as described in section.
