Description
Technical field
The utility model relates to safety installations field, particularly relates to a kind of explosion pressure relief device for pressurized container or pipeline.
Background technique
Blasting device is the important safety of pressurized container, pipeline.It can explosion under the temperature and pressure of regulation, and relieving pressure, ensures the safety of people's life and national wealth.Blasting piece device is made up of rupture disk and clamp holder two-part.Rupture disk is at the element demarcating explosion pressure release at bursting pressure and temperature, and clamp holder is then the auxiliary element of the suitable position attaching clamping rupture disk at container.Rupture disk safety installations has the advantages such as structure is simple, sensitive, accurate, No leakage, relieving capacity are strong.Reliably can work under the environment of thickness, high temperature, low temperature, corrosion, or the desired Safety device of ultrahigh pressure vessel.Rupture disk is the important safety preventing pressure facility generation superpressure from destroying, and is widely used in the industrial departments such as chemical industry, oil, light industry, metallurgy, nuclear power, dedusting, fire-fighting, aviation.
Blasting device under prior art conditions, splashes after rupture disk fragmentation after explosion in device interior overpressure, and the equipment be easy near destroying causes secondary injury, even injures staff, causes personal injury.
Model utility content
The utility model, in order to overcome deficiency of the prior art, to provide after a kind of rupture disk explosion without fragment without the rupture disk splashed.
The utility model is achieved through the following technical solutions:
A kind of explosion pressure relief device, comprise rupture disk and fixing device, described fixing device comprises gland, flange, bolt and nut, and rupture disk is fixed between gland and flange by bolt and nut, and flange is connected with the adapter of connectivity device inside; Be provided with the screen with gate hole between described gland and rupture disk, screen is arranged on the blasting direction of rupture disk, when explosion and crushing, even if generation fragment, fragment is blocked by screen, prevents fragment from splashing away, thus avoids fragment splashing cause damage and injure; Described rupture disk is antiarch shape, anti-shaped interior side is provided with two crossing grooves, the inner side of antiarch shape is the blasting direction of rupture disk, groove is set this side up, rupture disk is divided into several arc lobe, tear along groove when rupture disk is broken, arc lobe connects together after separating, and is unlikely to splashing and goes out.
The cross section of described groove is circular arc, and it is concentrated that arc-shaped groove can prevent channel bottom from producing stress.
Be provided with pad A between described screen and rupture disk, between rupture disk and flange, be provided with pad B.Pad is set and can plays seal action, prevent connection part from revealing.
Described rupture disk material is aluminium copper.
Compared with prior art, the beneficial effects of the utility model are: the utility model is provided with screen by the blasting direction front end at rupture disk, the fragment that screen can may occur when can stop explosion, prevent fragment damage equipment or injury workman, rupture disk arranges arc-shaped groove at blasting direction simultaneously, tear along groove when rupture disk is broken, reduce the generation of fragment.
