Abstract

<P>PROBLEM TO BE SOLVED: To provide a tool which can repair a damaged packing seat of a faucet by grinding it without taking the faucet off from the pipe of the faucet. <P>SOLUTION: The tool has means which are so arranged as to set the tool mainly comprising a shaft, a spring, a cap nut, a grinding stone and a handle on the faucet after the supply of water is stopped by fastening a main plug and grind the packing seat by rotating the grinding stone forced onto the packing seat of the faucet with the handle through the resilience of the spring. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydrant packing seat grinding tool, and more particularly, to easily grind a damaged hydrant packing seat without removing the hydrant from its piping. It is possible to use a hydrant packing seat grinding tool. Conventionally, replacement of top packing has been considered as a countermeasure against water leakage from the water inlet of a water tap, but the cause of water leakage is not only damage to the top packing but also corrosion of the packing seat of the water tap due to water leakage. There are many cases where the surface is damaged due to factors such as the above, and in such a case, water leakage could not be completely stopped. Therefore, in order to completely stop water leakage, it is necessary not only to replace the top packing but also to repair the damaged packing seat, but until now there was no tool that anyone could easily repair. Eventually, the water leak was left as it was, or the water tap with the damaged packing seat was removed from the pipe and replaced with a new water tap, which was very wasteful. [0004] The present invention provides a tool that can repair a damaged seat on a hydrant by grinding the surface of the hydrant without removing the hydrant from its tubing and without requiring special skills. To provide. [0005] As a means for solving the above-mentioned problems, a packing seat grinding tool for a water faucet according to the present invention is configured such that a spring and a cap nut having a hole are rotatably inserted into a shaft. The part has a generally disc-shaped grindstone, and the handle is fixedly attached to the shaft at the end on the side of the cap nut. [0006] To grind the packing seat of the damaged water tap, after closing the main cock to stop water, remove the spindle, cap nut, top packing and the like of the water tap and insert the tool into the water tap. Then, apply the grindstone surface to the packing seat, hold down the cap nut by hand against the spring reaction force, screw it into the screw part with the cap nut of the water tap, and set this tool to the water tap, By turning the handle, the packing seat is roughly ground by the reaction force of the spring on the surface of the grindstone. In this tool, since the grindstone surface always presses the packing seat in the vertical direction by the spring, anyone can easily grind the packing seat, which requires advanced technology, simply by turning the handle. Can be done. As is apparent from the above description, the use of the water tap packing seat grinding tool of the present invention allows anyone to easily grind a damaged packing seat without the need for advanced technology. In addition to completely stopping the leakage of water, the function of the hydrant is restored to the same condition as a new one, so that the necessity of replacement is eliminated, which is very economical. An embodiment of the present invention will be described below with reference to the drawings. 1 and 3 show an embodiment of the present invention, and FIG. 2 shows a water tap main body before setting the present invention. FIG. 1 is a front view of the present invention, and FIG. 3 is a front view when the present invention is set in FIG. In the present embodiment, a packing seat grinding tool for a water tap is provided with a spring 2 and a holed cap nut 3 rotatably inserted into a shaft 1 as shown in FIGS. A disk-shaped grindstone 4 is attached to the end of the side, and a handle 5 is attached to the end of the cap nut 3 by fixing it to the shaft 1 with bolts 6 and spring pins 7, respectively. Specifically, as shown in FIG. 3, when the present invention is set in the water faucet main body 8, the grindstone 4 always presses the packing seat 9 by the spring 2 in the vertical direction. Just by turning, the packing seat 9 can be correctly ground. However, the present invention is not limited to the above-described embodiment, and it is a matter of course that an adhesive may be used for fixing the grindstone, or a grindstone may be used in place of the grindstone. .
