Abstract

The invention discloses a pressure test tool for sealing pressure vessel welding beveled edges. The pressure test tool comprises a pressure test tool body and a pressure test connector. The right side face of the pressure test tool body is provided with annular welding beveled edge sealing grooves. Each welding beveled edge sealing groove comprises a sealing ring containing portion and a welding beveled edge matching portion. The welding beveled edge matching portions of the welding beveled edge sealing grooves are matched with the welding beveled edges of a pressure vessel. The sealing ring placing portions are internally provided with O-shaped sealing rings. The center of the pressure test tool body is provided with an assembling hole. The pressure test connector is assembled in the assembling hole of the pressure test tool body. The left end of the pressure test connector is further connected with a pressure device. The center of the pressure test connector is provided with a pressure conduction hole. The right side face of the pressure test tool body is provided with inclined holes communicated with the welding beveled edge sealing grooves. While the pressure test function is met, the problems that through a traditional pressure test method, welding beveled edges are prone to deformation and damage by bumping are solved, the whole structure is higher in safety, the cost is saved, and the pressure test tool is higher in using efficiency and simple and easy to operate.

Description

technical field [0001] The invention relates to a pressure test tool for a pressure vessel, in particular to a pressure test tool for sealing the welding groove of the pressure vessel. Background technique [0002] During pressure testing of pressure vessels (valves, flanges, pipes with welded groove ends), the welded groove ends must be sealed. Generally, the wall thickness of the welded groove end is about 1.5mm. The traditional pressure test method (port seal, inner wall seal) is easy to damage the O-ring. The product is damaged and scrapped. Therefore, there is an urgent need in the market for a pressure test tool that will not damage the welded groove and can effectively seal the welded groove. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a welding groove sealing pressure test tool that will not damage the welding groove, has high safety, saves costs, has high efficiency, and is ...
