Abstract
The utility model relates to a safety device for a rupture disk of an anti-arched slot type. The device includes an intensity film and also includes a seal film; the seal film is arranged below the intensity film; a circle on the intensity film near the seal surface along the outer circle of the arched surface is arranged into the shapes of an annular gear and a needle bar. Compared with the prior art, the safety device has the characteristics of still having higher stability under the situation of a very lower pressure, large discharging area, broad bursting pressure, and the like.
Description
Technical field
The utility model relates to rupture disk, is specifically related to the inverted arch slit type bursting disc safety installations.
Background technique
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.Blasting piece device be widely used in now industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection ground equipment in.
At present, the blasting piece device of domestic production, the bursting pressure of counter-arch shaped blasting piece can reach 0.1Mpa, its structure as shown in Figure 1 and Figure 2, the intensity film 1 one side settings side 2 of releasing, nameplate 3 is set on the side of releasing 2, and when the minimum bursting pressure of needs was lower than 0.1Mpa, existing traditional counter-arch shaped blasting piece was difficult to satisfy.
The model utility content
The purpose of this utility model is exactly to provide a kind of under the very low situation of pressure for the defective that overcomes above-mentioned prior art existence, still has very high stability, and discharge area is big, the low pressure explosion sheet device that the bursting pressure scope is wide.
The purpose of this utility model can be achieved through the following technical solutions: the inverted arch slit type bursting disc safety installations, this device comprises the intensity film, it is characterized in that, also comprise sealing film, the sealing film is arranged under the intensity film, and arch face outer ring, intensity film upper edge is near the shape of offering into ring tooth and shank on the circumference of sealing surface.
Described shank is crisscross arranged in intensity film periphery with the ring tooth.
Described intensity film is a pressure-sensing device, and described ring tooth is for causing brokenly element.
The material of described sealing film is a resistant material.
The described sealing film one side setting side of releasing is provided with nameplate on the side of releasing.
Compared with prior art, the utility model except have the antiarch rupture disk total be a little antifatigue, do not have the fragment in the time of bearing back pressure, explosion, also have following outstanding advantage: the receptance for mounting torque is lower; Need not to be equipped with knife rest, crocodile tooth etc. and cause brokenly element; Under the very low situation of pressure, still has very high stability; Discharge area is big; The bursting pressure scope is wide; The sealing film material can adopt different resistant materials, and not only medium is applied widely, and can save corrosion-resistant material.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1
Shown in Fig. 3～4, the inverted arch slit type bursting disc safety installations, this device mainly is made up of intensity film 1 and sealing film 4, sealing film 4 is arranged on the intensity film 1 time, intensity film 1 is the pressure-sensing device that cuts ring tooth and shank in advance, arch face outer ring, intensity film 1 upper edge is near the shape that is split into ring tooth 5 and shank 6 on the circumference of sealing surface, and shank 6 is crisscross arranged in intensity film 1 periphery with ring tooth 5, and ring tooth 5 plays the effect that causes brokenly element.Behind intensity film 1 pressurized, shank 6 positions become main supporting region, and be in unidirectional compressed state, when the load that acts on shank 6 two ends reaches its ultimate load and is intensity film buckling pressure, local buckling taking place suddenly and be bending deflection, ruptures because of stretching and shearing in shank top, intensity film upset back, and sealing film 4 is cut by the ring tooth 5 of intensity film 1, transmit pressure in the time of sealing film 4 sealings, the material of sealing film 4 can adopt different resistant materials.
The sealing film 4 one side settings side 2 of releasing can be provided with nameplate 3 on the side of releasing 2.
Claims (5)
