Claims

[Scope of utility model registration request]

In a cleaning piping system having a long water supply pipe that supplies cleaning liquid into a sealed container deeply submerged in a shielding water tank and a long drain pipe that discharges sewage in the same container to the outside of the shielding water tank, the cleaning surface of the sealed container is A plug with a built-in valve body in the fluid passage and a locking groove for a turning pole on the outer circumferential surface is fixed to the inlet port and contaminated water drain port with the plug facing upward. has sliding valves deep inside the fluid passageway that press against each other to open the flow path when connected to the plug, the wall thickness of the plug connection part is thick, and the opening end face on the plug connection side is placed on the end face side. It is formed on a tapered surface whose diameter widens as far as it goes, and furthermore, a tapered hole is formed through the thick part in a centrifugal direction, and a groove is formed that communicates with the tapered hole to a required depth, and the tapered hole is locked. At the same time as fitting the ball, a spring ring is fitted into the groove to fix the socket with the locking ball resiliently supported in the centripetal direction of the socket body downward, and the outer circumferential surface of the tip of the plug is placed inside the socket. A cleaning piping device equipped with a sealing ring.
