。Detailed Description of the Invention [Industrial Field of Application] The present invention provides a method of forming a connecting portion for a rotational operation shaft on both upper and lower sides, and forming a through hole for a flow path in a direction perpendicular to the rotational operation shaft. The present invention relates to a method of plating a valve element for a ball valve, in which the valve element is immersed in a plating solution for plating.

昭６０−５２７号公報）。In the above method of plating a valve body, by immersing the valve body in a plating solution, details that do not generally require plating are plated, which increases the plating cost. As shown in Fig. 6, * (20) is attached to the end openings (6B) and (6C) of the hollow part (6) formed within the wall thickness of the valve body (3). 3) as a single component to prevent the plating liquid from entering the hollow part (6) when the valve body is immersed in the plating liquid (for example, the method of preventing the plating liquid from entering the hollow part (6) 527 Publication).

あった。However, the plated valve body has the drawback that M (20) is also plated, and M (20) increases the weight and makes it expensive. , the air inside the hollow part (6) expands,
For this purpose, a lid (20) is provided for sealing the hollow part (6).
This method requires pressure resistance and mounting strength for the valve body (3), which has the disadvantage of making the entire valve body (3) more expensive. There was a drawback that (4) and the through hole (5) were plated.
本発明の目的は、必要な箇所のみをメッキする点にある
。An object of the present invention is to plate only the necessary parts.

ある。The characteristic means of the method of plating a valve body for a ball valve according to the present invention is that before the valve body is immersed in a plating solution, a cover that cannot be plated is attached to each of the connecting portions, and a pair of covers are attached on both sides of the through hole. When a lid body that cannot be plated is attached and the valve body is immersed in a plating solution, the plating solution is prevented from coming into contact with the connecting portions and the inner surface of the through hole, and the space inside the cover and the through hole are During the plating process, communicate with the outside air,
After plating the valve body, the cover and lid body are removed from the valve body, and the effects thereof are as follows.

全体が軽量になる。In other words, the inner surface of each connecting part and through hole is not plated because the plating liquid does not come into contact with the cover and lid, and the cover and lid cannot be plated either, so the valve body cannot be plated. Only the necessary areas are plated. Even if the plating solution is heated during the plating process, the space inside the cover and the through-hole are communicated with the outside air, so the inside of the cover and the through-hole do not become high pressure, and after the plating process, By removing the cover and lid from the valve body, the entire valve body becomes lighter.
従って、弁体の必要な箇所のみをメッキすることで、メ

きた。Therefore, by plating only the necessary parts of the valve body, the cost of plating can be reduced, and the lightweight and inexpensive cover and lid body can be used repeatedly, and the workability of plating can be maintained at low cost. I was able to improve it.
そして、更には、メッキ処理後の弁体は、カバーや蓋体
のない軽量で安価な製品に仕上げることができ、経済性
をより向上させることができた。Furthermore, the valve body after plating can be finished as a lightweight and inexpensive product without a cover or lid, thereby further improving economic efficiency.
