Claims

[Scope of Claim for Utility Model Registration] (1) Consisting of a pressurized air source and a purge circuit that connects the pressurized air source and the root of the pipe, with a pressure accumulation tank, a purge pressure regulating valve, and an on-off valve interposed in the middle. Pipe residual liquid purge mechanism characterized by: (2) Connect the pressure air source and the root of the pipe, and install a pressure storage tank, a purge pressure regulating valve,
and a purge circuit in which an on-off valve is interposed, in which a safety device consisting of a pressure protection valve that opens at a predetermined pressure or higher is interposed between the pressure air source and the pressure accumulation tank. Pipe residual liquid purge mechanism. (3) Following the pressure protection valve of the safety device, there is also a solenoid valve that operates in conjunction with a pressure switch that detects the pressure in the pressure accumulator tank. The pipe residual liquid purging mechanism described. (4) The pipe residual liquid purging mechanism according to "Utility Model Registration Claim (2) or (3)", wherein an on-off valve is disposed upstream of the pressure protection valve of the safety device. (5) The said pipe is a liquid supply hose for a tank truck, which is claimed in (1) or (2) or
(3) or (4)" purging mechanism for residual liquid in the pipe. (6) The compressed air source is an air compressor.
) or (4) or (5)”. (7) The air compressor is a purge mechanism for residual liquid in a pipe as described in "Claim (6) for Utility Model Registration," in which the air compressor is a pressure accumulator tank for an air brake of a tank truck.
