Abstract
The utility model relates to a rupture disc device with a rupture disc and pressure ring combination, which comprises a rupture disc, a press ring and a gasket. The rupture disc is disposed between the press ring and the gasket, and the rupture disc is integrally combined with the press ring. Compared with the prior art, the rupture disc device has the advantages of simple, light and convenient structure, easy processing, more convenient transport, installation and replacement, capability of effectively guaranteeing rupture pressure and the like.
Description
Technical field
The utility model relates to a kind of blasting piece device, especially relates to the combined blasting piece device of a kind of rupture disk and pressure ring.
Background technique
Blasting piece device has been widely used in the equipment that industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection now.Blasting piece device is by pressure differential, non-automatic urgent pressure relief device of closing, and is mainly used in protection pressurized container, pipeline or other closed system, and it is avoided because of excessively superpressure or vacuum cause destroying.
The required overpressure reliefs of industry such as the mainly fire-fighting of this class rupture disk, high pressure storage tank car design, existing structure is that rupture disk and pressure ring are that split is independent, the rupture disk of in transportation process, damaging easily, and obscure corresponding rupture disk and pressure ring, cause in proper functioning, can't guaranteeing bursting pressure, have potential safety hazard.In order to address these problems, satisfy market and user's needs, this is the problem that engineers and technicians need solve.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, light, change rupture disk and the combined blasting piece device of pressure ring easily.
The purpose of this utility model can be achieved through the following technical solutions:
The blasting piece device that a kind of rupture disk and pressure ring are combined is characterized in that, this device comprises rupture disk, pressure ring and pad, and described rupture disk is located between pressure ring and the pad, and this rupture disk and described pressure ring are combined into one.
Described rupture disk is a toroidal, encases the outer ring of described pressure ring behind the sealing surface flange of this rupture disk, and the sectional shape of the centre of rupture disk bottom is pre-arch upwards.
Described pressure ring is an annulus, and this pressure ring is nested in the rupture disk.
Compared with prior art, the utlity model has following advantage:
(1) simple in structure, light, and machine shaping easily;
(2) transportation, installation, replacing are conveniently, and be easy to use, convenient and swift;
(3) can guarantee effective bursting pressure.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
1 is that rupture disk, 2 is that pressure ring, 3 is pad.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
The blasting piece device that a kind of rupture disk and pressure ring are combined, its structure as shown in Figure 1, this blasting piece device comprises rupture disk 1, pressure ring 2 and pad 3, rupture disk 1 and pressure ring 2 are combined into one, pad 3 is located at the bottom of rupture disk 1.Rupture disk 1 is to pass through air pressure or oil pressure moulding by moulding mould special, and the sectional shape in the middle of its bottom is processed into pre-arch upwards, can play the effect of controlled blasting pressure.Pressure ring 2 is annulus of lathe in machining, the tolerance grade of strict guarantee cylindrical and endoporus, the connection frictional force after guaranteeing to make up and the bore of releasing of rupture disk 1, by encasing the outer ring of pressure ring 2 behind the rupture disk 1 sealing surface flange, pressure ring 2 is nested in the rupture disk 1, utilize the gap of combined mould to guarantee to become one after the flange of rupture disk 1 and pressure ring 2 makes up, even rupture disk 1 normal explosion can not thrown off yet, because flange has been arranged, increased the radial pull between rupture disk 1 and the pressure ring 2, thereby in the moment of explosion, rupture disk 1 can not cause rupture disk 1 to take out the limit phenomenon owing to the frictional force that impacting force causes inadequately is too small, thereby has guaranteed the bursting pressure precision of rupture disk 1.
Claims (3)
1. rupture disk and the combined blasting piece device of pressure ring is characterized in that this device comprises rupture disk, pressure ring and pad, and described rupture disk is located between pressure ring and the pad, and this rupture disk and described pressure ring are combined into one.
2. a kind of rupture disk according to claim 1 and the combined blasting piece device of pressure ring, it is characterized in that, described rupture disk is a toroidal, encases the outer ring of described pressure ring behind the sealing surface flange of this rupture disk, and the sectional shape of the centre of rupture disk bottom is pre-arch upwards.
3. a kind of rupture disk according to claim 1 and the combined blasting piece device of pressure ring is characterized in that described pressure ring is an annulus, and this pressure ring is nested in the rupture disk.
