When the pressure relief device is used, the back cover and the main shell body need to be pressed through a press machine, the convex blocks are clamped into the clamping grooves, the height of the convex blocks and the depth of the clamping grooves can be changed in the redesign process, the quantity of the convex blocks and the quantity of the clamping grooves are changed, the connection strength of the convex blocks and the connecting grooves is further changed, the clamping grooves and the convex blocks are guaranteed to be separated when the internal pressure of the shell body reaches a certain value, the back cover is prevented from falling off, and pressure relief. Because the back cover is wholly fallen off, the rapid pressure relief of the interior of the shell can be ensured, the glass plate at the observation window is prevented from being broken due to untimely pressure relief, and the damage of deformation and the like of the shell is also avoided. The shell after pressure relief can be used for pressing the back cover again, and the shell can be reused.
The glass plate is laminated glass, and is made by sandwiching a layer of transparent organic compound film between two layers of glass sheets, so that even if the glass plate is broken, fragments can be adhered to the film, the surface of the glass is smooth, and the glass fragments are prevented from falling to cause danger.
Novel safe pressure gauge shell, simple structure can realize quick pressure release, prevents that the explosion of pressure gauge shell from taking place to damage, has guaranteed personnel's safety and equipment safety when using.
