Title: Hiroyuki Sasakura: Innovator in Gasket Technology

Introduction

Hiroyuki Sasakura is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of gasket technology, holding a total of 2 patents. His innovative designs focus on improving sealing properties and enhancing the functionality of gland packing boxes.

Latest Patents

One of his latest patents is for a non-asbestos gasket. This invention improves upon a metal gasket with a corrugated portion that is advantageous for sealing properties. The non-asbestos gasket features a three-layer structured sealing portion, which includes a core layer made of a metal plate formed into a concentric circle-like corrugated shape. The surface layers are made of expanded graphite and are stacked on both the front and back faces of the core layer. The design ensures that the core layer protrudes from the surface layers at the outer circumferential end, while the surface layers cover the core layer at the inner circumferential end, thereby enhancing the sealing property.

Another significant patent by Sasakura is the structure of a gland packing box. This invention enhances the lubricating and cooling functions of the seal part by incorporating at least one dislocating part. This part allows for partial dislocation in the axial direction of the gland packing, which is externally mounted on a rotary shaft. The dislocation causes part of the annular gap formed between the gland packing holding member and the rotary shaft to overlap with the internal surface of the gland packing, facilitating fluid movement into the inner surface of the overlapping gland packing as the rotary shaft rotates.
