Embodiment Construction

[0036] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of examples.

[0037] Such as figure 1 As shown, a hole opening device of this embodiment is used to open a pressure relief hole on the tank body. The hole opening device includes a placement part 1 and a hole opening part 2. The placement part 1 is used to place the tank body, and the hole opening part 2 is connected with the placement part 1 and can rotate relative to the placement part 1, and the hole opening part 2 opens a hole for the tank body after placing the tank body on the placement part 1.

[0038] In this embodiment, one end of the placing part 1 is provided with a hinged part 15, and the opening part 2 is rotatably connected to the hinged part 15. When the opening device is in use, the tank to be decompressed can be put into the placing part 1. By turning the opening part 2 on the placement part 1 to open the tank body...

Abstract

The invention discloses a perforating device. The perforating device is used for perforating a pressure relief hole in a tank body and comprises a placing part and a perforating part, wherein the placing part is used for placing the tank body, the perforating part is connected with the placing part and can rotate relative to the placing part, and the tank body is perforated by the perforating partafter the tank body is placed on the placing part. According to the perforating device, when in use, the to-be-decompressed tank body can be placed into the placing part, perforating and decompressing are conducted on the tank body by rotating the perforating part on the placing part, the tank body can be prevented from bouncing off due to impact of external force, high-pressure liquid in the tank body can be prevented from being sprayed to people and hurting people, and the perforating device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a hole opening device. Background technique [0002] PT flaw detection agent is often used for repairing FCB welds in straight work areas of shipbuilding. After the PT flaw detection agent is used up, there is still pressure in the tank. If the temperature reaches a certain level, the tank will explode. Therefore, the tank body of PT flaw detection agent Pressure relief is very necessary. Nowadays, the pressure relief of the tank body is generally hit with a hammer to break the tank body and release the pressure, but the tank body may bounce off and hit people when knocked in this way, and the residual liquid in the tank body may also shoot out and splash into people's eyes or There are certain safety hazards on the exposed skin. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hole-opening device in order to overcome the defect that the tank body of the PT flaw ...
