Explosion venting bolt system

Abstract

An explosion venting bolt system comprises a screw. A nut is fixedly arranged above the screw. A waterproof gasket is arranged below the nut and sleeves the screw. A lead nut is arranged below the waterproof gasket and arranged on the screw in a matched manner. A traction hole is formed in the lower end of the screw and is a through hole, and the axis of the traction hole and the axis of the screware in intersection and form the included angle. The lead nut is sleeved with a protection cap, the interior of the protection cap is arranged to be in a hexagon nut shape to be matched with the leadnut, a high-strength steel wire is fixedly connected to the inner bottom of the protection cap, and the other end of the high-strength steel wire is connected with the traction wire. In short, secondary damage caused by splashing objects generated during explosion of an explosion venting wall is reduced, and better explosion venting safety performance is provided; and meanwhile, machining and installing are convenient, dust invading is avoided, and a better explosion venting effect is guaranteed.

Description

technical field [0001] The invention relates to the field of explosion venting fasteners, in particular to an explosion venting bolt system. Background technique [0002] The explosion-venting wall is usually a light-weight pressure-relieving wall used in industrial and civil workshops, boiler rooms, dangerous goods warehouses, etc., and the explosion-venting bolt is an explosion-venting accessory that connects the explosion-venting wall with the beam. When an explosion occurs, the venting The explosion wall is easy to open at the explosion venting bolt, thereby releasing the explosion energy and reducing the destructive force of the explosion. The existing pressure relief bolt connection device mainly reduces the energy absorption of the plate through the metal sleeve with anti-collapse function arranged on the surface of the bolt or the gasket arranged at the nut of the screw rod, thereby releasing the explosion energy and reducing the explosion destructive force , howeve...

AI Technical Summary

Problems solved by technology

The existing pressure relief bolt connection device mainly reduces the energy absorption of the plate through the metal sleeve with anti-collapse function arranged on the surface of the bolt or the gasket arranged at the nut of the screw rod, thereby releasing the explosion energy and reducing the explosion destructive force , however, this kind of pressure relief bolt connection device needs to open a relatively large hole in the structure, and the size of the hole affects the effect of explosion relief. Not only is it difficult to process, but there are also situations such as installation eccentricity. When the bolt connection device explodes, the plate is prone to blast under the action of a huge shock wave, and the splash produced by it will often cause secondary damage, and after a long time, dust will enter the inside of the nut and gasket, which will affect the explosion venting Effect
