The invention provides a large-diameter nozzle manual sealing device, comprising a base, a control device, a tightening device and a seal device; the control device comprises a pair of operating handles; the tightening device comprises a pair of tightening rods arranged in a pin bushing, an elastic reset element and a blocking stopper for auxiliary positioning; the tightening rods run through the base and are connected with the operating handles; the tightening rods can axially slide in the pin bushing; the seal device comprises a seal base and a seal piece which is connected with the seal base and used to tightly press the nozzle; wherein, the control device, the tightening device and the seal device are fixed on the base. When the large-diameter nozzle manual sealing device is in use, the handles are manually operated, and the tightening rods are strained, so that the seal piece can tightly press the nozzle to realize reliable manual sealing. The invention has simple structure and is easy to operate, which can effectively realize manual sealing of large-diameter nozzles and can be widely used in the engineering field.
Description
technical field [0001] The invention relates to a large-diameter nozzle manual plugging device, which is mainly used for plugging the interface of a product and injecting compressed air when performing a leak test in product quality inspection, and belongs to the field of mechanical processing and assembly. Background technique [0002] At present, large-diameter nozzle manual plugging devices are often used for leak testing. In the field of mechanical processing and assembly, it is necessary to perform quality inspections on processed and assembled parts in specific procedures to ensure that the quality of finished and semi-finished products on the production line is qualified. And remove unqualified products at any time to avoid unqualified semi-finished products from completing all processes, resulting in unnecessary waste of manpower and material resources. A widely used detection method is the leak test. The leak test is an automatic air tightness test with dry air as t...
