Title: Shaft sealing method for rotary valve
Inventor: KAZEMOTO AKIRA
IPC: F16J15/40
Filed: 1993-11-01
Abstract: PURPOSE:To prevent foreign matter and noise from producing by providing a gas feed hole to a space for filling shaft seal material, making an inner clearance larger slightly than an outer clearance, and blowing the fed gas to a valve through the inner clearance. CONSTITUTION:In a rotary valve, a gas feed hole 3 is drilled to a space for filling shaft seal material 4 which is located adjacent to a gland 2 around a shaft 1. Also air, nitrogen gas, etc., fed through the gas feed hole 3 made to flow into a product side, i.e., into a valve through an inner clearance 5. By this, powder and granular material is prevented from entering the gland 2, i.e., the inner clearance 5. Then the inner clearance 5 is made larger slightly than an outer clearance 6. and the outer clearance 6 is reduced as small as possible. In addition, packings 7 and 8 are the gas sealing material of the shaft 1. Thus production of foreign matter and noise at the shaft seal part can be eliminated, and also repair is not required.

Abstract: PURPOSE:To effectively densify a coating layer by a method wherein a coating layer composed of a heat-resistant and abrasion-resistant material is formed to a base material and an outer shell layer composed of boron nitride is subsequently formed thereon to encapsulate the base material in a hermetically sealed capsule along with a glass powder and, after vacuum sealing, the whole of the hermetically sealed capsule is subjected to high temp. isotropic compression treatment. CONSTITUTION:A coating layer composed of a heat-resistant and abrasion-resistant material is formed to the surface of a base material and an outer shell layer composed of boron nitride is subsequently formed to the surface of the coating layer and this base material is encapsulated in a hermetically sealed capsule along with a glass powder to be subjected to vacuum sealing and, thereafter, the whole of the hermetically sealed capsule is subjected to high temp. isotropic compression treatment. As the base material, iron or stainless steel is pref. and, in order to improve the adhesion to the base material, the coating layer may be formed as a combined double-layer. The outer shell layer seals the pores of the coating layer and prevents the penetration of molten glass in pores. Because of this, boron nitride is used. The base material having the coating layer and the outer shell layer thus formed thereto is encapsulated in the hermetically sealed capsule and this capsule is subjected to high temp. isotropic compression treatment.
