A self-relieving bolt

Abstract

The invention discloses a self-pressure relief bolt, and belongs to the technical field of fasteners. The self-pressure relief bolt comprises a bolt head and a screw rod. A screwdriver groove is formed in the upper central position of the bolt head. Threads are formed on the outer ring surface of the screw rod. The screw rod is arranged at the lower central position of the bolt head. A pressure relief channel is arranged at the central position of the bolt head and the screw rod in the vertical axial direction. A plurality of corresponding pressure relief openings are formed in the screw rod from top to bottom. The pressure relief channel is provided with a guide pipe, and a fixed plate is welded to the lower end of the guide pipe. The fixed plate is welded and fixed to the lower portion of the screw rod, a spring is arranged in the guide pipe, one end of the spring is connected with the fixed plate, a sliding block is arranged at the other end of the spring, the sliding block is arranged on the upper portion of the guide pipe, and the sliding block is positioned in the pressure relief channel and is in sliding connection with the inner portion of the pressure relief channel. The self-pressure relief bolt has an automatic pressure relief function and can effectively reduce the pressure in a closed container.

Description

technical field [0001] The invention relates to a self-pressure relief bolt, which belongs to the technical field of fasteners. Background technique [0002] In some production equipment, bolts are often used to connect fasteners. Some confined spaces are not used as pressure vessels and will not produce pollution sources of exhaust gas. They are often ignored and pressure relief protection devices are not used, but this often results in some costs. Avoidable accidents, in order to solve the deficiencies of the prior art, the present invention provides a self-relieving bolt. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a self-pressure-releasing bolt, which can effectively release the pressure in the space, improves the safety performance, and has a simple structure and low cost. [0004] The technical scheme adopted in the present invention is: [0005] A self-relieving bolt, comprising a bolt head...
