Abstract
A pressure relief device with tearing openings is composed of a pressure relief cover plate, a nylon bolt and a metal bolt, wherein the pressure relief cover plate is buckled inversely at a pressure relief port at the top of a high-pressure switch cabinet, one end of the pressure relief cover plate is connected with the cabinet top through the nylon bolt, the other end of the pressure relief cover plate is connected with the cabinet top through the metal bolt, and two chamfer-shaped openings are symmetrically arranged on one edges close to the metal bolt on the front and back side walls of the pressure relief cover plate. The pressure relief device is characterized in that a pair of tearing openings is symmetrically arranged at front and back ends of the top wall of the pressure relief cover plate and extends to the middles of the two chamfer-shaped openings respectively. The pressure relief device has the advantages that the structure is simple, the cost is low, the pressure relief is rapid, the pressure relief effect is good, and the risk of accidents is prevented from being enlarged.
Description
Technical field
The utility model relates to a kind of pressure relief device, and particularly a kind of pressure relief device with tearing port is applicable to the pressure relief device that various employings destroy the high-tension switch cabinet of sheet mode pressure release.
Background technology
At present, the common pressure release mode that adopts of existing pressure relief apparatus of high voltage switch cabinet has the hinge open-close ways and destroys two kinds of sheet modes; Wherein, the pressure relief device that adopts the pressure release of hinge opening and closing mode requires relatively largely to installing space, therefore, can only use the pressure relief device that destroys the sheet mode pressure release under some specific conditions.And existing employing destroys the pressure relief device of sheet mode pressure release, it is the pressure release cover plate that is folded by the thick steel plate in the 1.5mm left and right sides, nylon bolt and metal bolts form, when meeting accident accidental detonation in the high-tension switch cabinet, a large amount of gases at high pressure are upwards poured into the pressure release cover plate in high-tension switch cabinet, the nylon bolt fracture that pressure release cover plate one end is connected with the high-voltage switch cabinet top, then deformation upwards occurs at the side plate near nylon bolt in the pressure release cover plate, and the other end of pressure release cover plate is connected with the cabinet top by metal bolts, therefore deformation does not occur at the side plate near metal bolts in the pressure release cover plate, again owing to before the pressure release cover plate, one side near metal bolts on the rear two side is arranged with two chamfering shape openings, so the pressure release cover plate near the side plate of nylon bolt in two chamfering shape opening part generation bendings, the high pressure draught that gases at high pressure form releases at the side plate near nylon bolt from the pressure release cover plate.Above-mentioned pressure relief device has played the purpose of pressure release, but, the pressure release cover plate is still higher at the timber intensity of two chamfering shape opening parts, so sometimes can not causing the pressure release cover plate smoothly, high pressure draught produces enough distortion at the side plate near nylon bolt, thereby the pressure release cover plate can not be opened in two chamfering shape opening part bendings at the side plate near nylon bolt, high pressure draught just can not release smoothly from rotine positioning like this, and other critical positions ejections in the high-tension switch cabinet, so that enlarged accident.
The utility model content
The purpose of this utility model is: design a kind of simple in structurely, with low cost, with the pressure relief device of tearing port, this pressure relief device pressure release is effective rapidly in pressure release, has avoided the danger of expansion accident.
The purpose of this utility model can realize by following technical proposals:
This is with the pressure relief device of tearing port, by the pressure release cover plate, nylon bolt and metal bolts form, the pressure release cover plate tips upside down on the upper pressure relief opening place, cabinet top of high-tension switch cabinet, one end of pressure release cover plate is connected with the cabinet top by nylon bolt, the other end of pressure release cover plate is connected with the cabinet top by metal bolts, before the pressure release cover plate, one side near metal bolts on the rear two side is arranged with two chamfering shape openings, it is characterized in that: the roof at described pressure release cover plate is gone forward, rear end positions, symmetry has a pair of tearing port, and two tearing ports extend to respectively the middle place of chamfering of two chamfering shape openings.
The utility model has the advantages that: this pressure relief device is under the prerequisite that does not increase any cost of manufacture, only offer a pair of tearing port at former pressure relief device body, increased weak pre-breakdown point, therefore, the pressure release cover plate can be opened at two tearing ports and the smooth bending of two chamfering shape opening parts at the side plate near nylon bolt, thus rapidly pressure release; Therefore this pressure relief device is simple in structure, with low cost, and pressure release is rapid, and pressure release is effective, has avoided the danger of expansion accident.

Embodiment
Shown in Fig. 1-5, this is with the pressure relief device of tearing port, by pressure release cover plate 4, nylon bolt 1 and metal bolts 5 form, the cabinet that pressure release cover plate 4 tips upside down on high-tension switch cabinet pushes up pressure relief opening place on 6, one end of pressure release cover plate 4 is connected with cabinet top 6 by nylon bolt 1, the other end of pressure release cover plate 4 is connected with cabinet top 6 by metal bolts 5, before pressure release cover plate 4, one side near metal bolts 5 on the rear two side is arranged with two chamfering shape openings 2, it is characterized in that: the roof at described pressure release cover plate 4 is gone forward, rear end positions, symmetry has the middle place of chamfering that a pair of tearing port 3, two tearing ports 3 extend to respectively two chamfering shape openings 2.
This operation principle with the pressure relief device of tearing port is: as shown in Figure 1, this pressure relief device is under the initialization state, the cabinet that back-off is installed in high-tension switch cabinet pushes up pressure relief opening place on 6, pressure relief opening sealing with high-tension switch cabinet, the accidental detonation if meet accident in the high-tension switch cabinet this moment, a large amount of gases at high pressure at first accumulate in pressure release cover plate 4 times and according to diffusion around the direction of arrow court shown in Figure 1, high-tension switch cabinet body faces the whole danger that destroys; As shown in Figure 2, this pressure relief device is under the pressure release operating state, owing on the roof of pressure release cover plate 4, have in advance a pair of tearing port 3, so that at explosion time, the nylon bolt fracture that pressure release cover plate 4 one ends are connected with the high-voltage switch cabinet top, and pressure release cover plate 4 in the intensity at two tearing ports, 3 places far below its intensity in all the other positions, and two tearing ports 3 extend to respectively again the middle place of chamfering of two chamfering shape openings 2, therefore, the pressure release cover plate can be opened at two tearing ports 3 and the two smooth bendings in chamfering shape opening 2 places at the side plate near nylon bolt, thereby rapidly pressure release, high pressure draught releases smoothly according to the direction of arrow shown in Figure 2 pressure relief opening from the cabinet top 6 of high-tension switch cabinet.
