の継手装置。[Scope of claim for utility model registration] 1. The inner pipe has a plug at one end and a socket at the other end.
The plug has a sealing function on the outer periphery of the tip end of the head and a locking groove on the outer periphery, and the socket is provided with a connection hole into which the plug is fitted, and the socket is provided with a connection hole into which the plug is fitted. The socket body includes a locking ball that is removably locked to a stopper groove and a locking/disengaging operation tube for the socket body, and a mounting cylinder piece that attaches the socket body to the inner tube end, and the center of the inner end of the mounting cylinder piece. A valve seat is provided in the fitting section, and a valve element is provided in the distal end of the fitting part inside the mounting cylinder piece of the socket body, which is biased by a coil spring so as to come into contact with the valve seat. A coupling device for a chemical liquid injection rod, characterized in that the inner part of the outer tube side is closed by contact between the operating tube end of the rod and an annular receiving portion provided on a coupling of the outer tube. 2. In the joint of a screw-in type chemical injection rod, a valve support body equipped with a valve element that is given thrust by a coil spring is attached to the inner end of the inner pipe connection hole against the valve seat provided on the liquid supply side. A coupling device for a chemical liquid injection rod, characterized in that a valve is installed inside the valve and opens a flow path when liquid is supplied to a liquid flow hole on the outer tube side.
