Abstract

A coil cooler air tightness detection device comprises a groove-shaped hinge plate assembly, clamp-shaped hinge assemblies, a connecting rod and a rubber water tank, the clamp-shaped hinge assemblies are arranged at two ends of the groove-shaped hinge plate assembly and comprise hinge pieces, arc-shaped jaws are arranged on the hinge pieces, and air bags are laid on the arc-shaped jaws; connecting rods are respectively hinged with the side plates and the hinging pieces to form four groups of symmetrical four-rod mechanisms; and the rubber water tank is fixed in the groove-shaped hinge plate assembly and is in sealed connection with the hinge piece. Under the effect of self gravity, the side plates rotate towards the inner side, the hinge pieces clamp the coil pipe, the air bags on the hinge pieces seal the circumferential direction of the coil pipe, and at the moment, the water surface in the rubber water tank is higher than the coil pipe; when the side plates rotate towards the outer side, the hinge pieces loosen the coil pipe, and at the moment, the water level in the rubber water tank is lowered. According to the invention, the volume of the rubber water tank is changed through the four-rod mechanisms, so that the water surface submerges the coil pipe, and the coil pipe is sealed, so that the airtightness of the welding part of the coil pipe is detected.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to an air tightness detection device for a coil cooler. Background technique [0002] like figure 1 As shown, for a large coil cooler, the total length of the coil 1 is more than hundreds of meters. Restricted by the length of the pipe fittings and the pipe bending process, the coiled pipe 1 with a length of more than 8 meters needs to be spliced ​​by butt welding. Due to the large number of butt welds, there is a great risk of leakage in the spliced ​​coil, and it is necessary to perform a pressure leak test on the spliced ​​coil in the water tank. At present, the overall pressure leak test method is adopted, and the coil cooler is hoisted into the water tank as a whole through the crane. The problem that this detection method exists, the one, needs very big and deep water tank, leak point is difficult to be found during leak test; [0003] Similarly, there are also problems in...
