This utility model discloses a cold-drawn tube crack detection and sorting system, belonging to the field of sorting systems. It includes a frame, with a conveyor belt internally connected via a rotating rod and a linkage rod. The conveyor belt has pre-drilled grooves, and tubes are fitted into these grooves. Detectors are fixedly connected to the top and bottom walls of the frame. A feeding device is installed on the top of the frame. The rotating rod and linkage rod are arranged in parallel, and two sets of conveyor belts are driven to pulleys fixedly fitted to the outer rings of the rotating rod and linkage rod. In this utility model, rotating a motor drives a wheel fixedly fitted to a drive shaft. The outer wall of the tube in the columnar groove slides against the inner wall of the columnar cavity, and the wheel rotates synchronously with the tubes pre-drilled in the columnar groove until the tubes in the columnar groove are aligned with the discharge port, thus enabling intermittent feeding of the tubes and facilitating subsequent inspection operations.

The utility model discloses an energy-saving gas water heater, which relates to the technical field of water heaters and comprises a mounting box, a water inlet valve is connected to one side of the bottom of the mounting box in a penetrating manner, a gas heating device is fixedly connected to the top of the water inlet valve, and a smoke exhaust pipe is fixedly connected to the top of the gas heating device. The bottom of the fuel gas heating device is fixedly connected with a heat preservation pipe. The igniter is started to heat fuel gas at the top of the combustor, the combustion sheets are ignited by the temperature rise of the fuel gas, the combustion sheets are installed at equal intervals, so that the serpentine pipe clamped in the combustion sheets is heated more uniformly by the temperature of outer flame, the serpentine pipe has a three-end heating length, the heating time of tap water in the serpentine pipe is longer, the fuel gas emission can be reduced, and the energy consumption is reduced. Heated water enters the threaded pipe, so that the temperature of the threaded pipe can be kept stable, the temperature of the heated water stored in the heat preservation pipe cannot be reduced, and after the boiled water is used, the heat-preserved water can be discharged for use, and a large amount of cold water does not need to be discharged.
