Abstract

The utility model relates to a fast changeable anti-explosion device which is characterized in that a connecting pole (9) and a rib plate (8) are arranged in the upper end of a casing 7, four fan-shaped openings (14) are formed on end surface, a sealing gasket and a superpressure break sheet (5) are arranged on the fan-shaped openings (14), a fan-shaped hole (13) on an upper cover (14) corresponds to one fan-shaped opening (14), and the upper cover (14) is pressed tightly by a screw bolt (1) and a screw nut (2). The utility model has the advantages that the change is convenient; the change time is shortened; the pipeline leak is reduced; once the superpressure break sheet (5) is installed, the superpressure break sheet (5) can be used four times.

Description

The utility model relates to a kind of safety protection device, particularly relates to a kind of quick-replaceable flameproof apparatus.

Existing chemical industry closed cycle system in order to prevent the ultrahigh pressure accident of blasting, often needs the safety anti-explosive device.The structure of this device is that the end at housing is connected with high pressure pipe line, and the other end is equipped with superpressure explosion plate and connects with flange plate.When the pressure overrate of system, the explosion of superpressure explosion plate makes the safety of system decompression protective system, prevents the generation of explosive accident.When this structure in accident the back replacing takes place, need turn on all nuts on the flange plate, change the overpressure failure plate, tightening nuts needs the time long again, thereby intrasystem gas or liquid are leaked in a large number.

The purpose of this utility model is that a kind of quick replacing of design reduces the quick-replaceable flameproof apparatus that leaks.

The utility model is achieved in that quick-replaceable flameproof apparatus comprises housing, loam cake, overpressure failure sheet, sealing gasket, it is characterized in that there is an attachment post in central authorities in the top of housing and is connected with housing by the floor of four symmetries, the upper-end surface of housing has four fan-shaped mouthful, above each fan-shaped mouth a superpressure sliver and a sealing gasket are arranged, tapped hole and bolt are arranged above the attachment post, a screw hole of loam cake central authorities passes bolt and is pressed in above the overpressure failure sheet again, and corresponding one of them the fan-shaped mouth in the position that makes the fan shaped borehole that covers, nut is arranged on the bolt.

Following accompanying drawing has provided an embodiment of the present utility model, is described further in conjunction with the accompanying drawings.

Fig. 1 is an overall structure principal section schematic representation of the present utility model;

Fig. 2 is the schematic top plan view of the utility model housing;

Fig. 3 is the A-A generalized section of Fig. 2;

Fig. 4 is the schematic top plan view of the utility model loam cake;

Fig. 5 is the B-B generalized section of Fig. 4.

The symbolic representation of Fig. 1-Fig. 5 is as follows: bolt 1, nut 2, pad 3, loam cake 4, overpressure failure sheet 5, sealing gasket 6, housing 7, floor 8, attachment post 9, tapped hole 10, lower flange 11, circular hole 12, fan shaped borehole 13, fan-shaped mouthful 14, interior conocave plane 15, screw hole 16, stiffening rib 17, boss platform 18, inner cylindrical surface 19.For reliable sealing, conocave plane 15 in around the fan-shaped mouth 14 in the upper-end surface of housing 7, having.The stiffening rib 17 of a boss platform 18 and four symmetries that are connected with boss platform 18 is arranged above the loam cake 4, and screw hole 16 passes the center of boss platform 18, an inner cylindrical surface 19 is arranged below the loam cake 4.

The utility model is to use like this, the lower flange 11 of housing 7 lower ends docks with piping flange, fastening by circular hole 12 usefulness screws, lay sealing gasket 6 and overpressure failure sheet 5 on the conocave plane 15 in around the fan-shaped mouth 14 of housing 7 upper ends, with the fan shaped borehole on the loam cake 4 13 corresponding to one fan-shaped mouthfuls 14, and the upper end that inner cylindrical surface 19 is buckled in housing 7 compressed, nut 2, pad 3 are tightened with bolt 1.When envelope close system ultrahigh pressure reaches rating value, gas in the pipeline or liquid by with fan shaped borehole 13 corresponding fan-shaped mouthful 14 with 5 explosions of overpressure failure sheet, release through the fan shaped borehole 13 of loam cake and to reach the decompression safety protection.Only need unscrew nut 2 during replacing, loam cake is revolved turn 90 degrees, make fan shaped borehole 13 aim at another fan-shaped mouthful 14, at this moment, pushed down by loam cake, nut has been tightened to be finished replacing for fan-shaped mouthful 14 that the overpressure failure sheet has broken.

The utility model has the advantages that it is convenient to change, and shortens the replacing time, reduces pipe leakage. And the overpressure failure sheet once installs, and can use four times.
