PURPOSE:To provide a valve where a valve body and a valve rod are coupled to each other by a pin, which can show enough corrosion protective effect by externally covering the valve body and the valve rod, covering the periphery of a pin hole of the valve body with hardening resin, screwing plugs on both ends of the pin in such a manner as to be brought into contact with the outer surface of the valve body, and filling hardening resin between the pin and the plugs. CONSTITUTION:A valve rod 5 is fitted in an insertion hole 6 of a valve body 4 externally covered with resin (a), and a taper pin 7 is driven extending over the valve body and the valve rod. Both end surfaces of the pin 7 are provided with tapped holes, and filled with hardening resin 11 such as epoxy resin. The screw portion 9 of a plug 8 is engaged with the tapped hole of the pin end surface to be fixed thereto like a cover so as to prevent the hardening resin 11 from slippind off due to a shock. |
