DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is intended to localize spot defects in the glass lining coating of the corrosion resistant glass lining equipment used for carrying out reactions and treatments in the chemical and food industries. Regarding the glass lining repair screw for repairing.

(Prior Art) In a glass lining device, it is necessary that the liquid contact surface of the metal substrate constituting the device is entirely covered with a continuous, defect-free, corrosion-resistant glass lining, which is not continuous in terms of the device configuration. The possible seams are unavoidable, and we have added high corrosion resistant materials such as PTFE and tantalum. If a small defect that impairs the continuity of the glass lining coating is generated for some reason, the corrosion of the base metal rapidly progresses from there, resulting in large damage.

(Problems to be Solved by the Invention) However, each of the conventional repairing techniques has a problem. That is, in the food industry where corrosion resistance is not required severely, resin repair such as epoxy resin is often adopted, but there is a concern that deposits are likely to occur on the repaired surface and the quality of high-grade liquor, wine, etc. is adversely affected.

The glass lining repair plug of Japanese Utility Model Publication No. 34-19754 has a large curvature at the peripheral edge of the umbrella-shaped flange, so the residual stress in the glass lining coating of this part becomes large and mechanical stress is applied to this part by mounting, so the plug itself Damages the glass lining coating. Moreover, since the shape of the protrusion for tightening the plug is square, it is difficult and time-consuming to manufacture a dedicated tightening tool.

(Means for Solving the Problems) In order to achieve the above object, the glass-lining repair screw of the present invention comprises a circular, disk-shaped head and an integral threaded stem portion for mounting, and the head is A peripheral part is formed in a substantially semi-circular cross section and slightly recessed from the plane. A mounting threaded stem part is formed vertically below the center of its lower surface, and a small-diameter projection part is eccentric from the center on its upper surface. Is formed so as to be integrally projected from the upper surface so as to be connected with a smooth curved surface to form a metal base, and a continuous glass lining coating is applied to the surface of the metal base from the upper surface to the lower surface of the head.

The repair screw of the present invention has a small size, but the head of the base metal has a peripheral curved surface with the largest radius of curvature in its size ratio.
Since it is formed in the outer shape surrounded by the projection connecting curved surface and the flat surface, the residual stress generated in the continuous glass lining constructed on the surface is small. Therefore, the glass lining coating on the head will not be damaged even if the tightening force required for mounting is applied.

This base metal is machined by lathe processing to set the eccentric axis of the small-diameter projection with the center eccentric from the center axis to machine the projection and the flat top surface, and set the center to the center axis to set the center to the bottom surface and the mounting screw. It can be easily and accurately manufactured by processing the stem portion. The fixture for the jig can also be easily and accurately manufactured by using only a lathe, and therefore local mechanical concentrated stress is not applied during fastening.

Since this glass lining repair screw has a glass lining coating (3) on a metal substrate having a rounded surface shape with a radius as large as possible, the glass lining repair screw can have a sound glass lining with little residual stress. . Therefore, it is possible to complete a repaired part with a perfect seal by strongly tightening it by using a dedicated fastener that can be accurately manufactured by utilizing the eccentric protrusion (1c). Since this repaired part has a glass lining surface, it has less adhesion of equipment treating material than the metal screw of the prior art, and it is small including the Teflon gasket and has the same color as the equipment glass lining, so it is not conspicuous. Such repair screws, gaskets, and fasteners are stocked by glass lining manufacturers as standard products, and can be provided as needed by the user to perform repairs relatively easily, so repair costs are low and repair time is low. Can also be shortened.
