Abstract
The utility model discloses a pressure test device for an anti-explosion membrane. The pressure test device is characterized by comprising a bracket, a primary cylinder, a secondary cylinder, a flange a used for clamping an anti-explosion membrane and a barometer, wherein the air outlet of the primary cylinder is connected with an air inlet b of the secondary cylinder; the upper side of the secondary cylinder is open and the flange a is arranged on the upper side of the secondary cylinder; the lower piece of the flange a is fixed with the secondary cylinder and the internal diameter of the upper piece of the flange a ranges from the internal diameter to the external diameter of the ring-shaped rolled-up edge of the anti-explosion membrane. Through the design, impact caused to the anti-explosion membrane by a tested gas is avoided, additional pressure on the anti-explosion membrane is eliminated, accordingly, the pressure test accuracy of the anti-explosion membrane is improved; meanwhile, the tested gas can be replaced with heated water, so that the conditions of a graphite desorption tower can be better simulated, and further, the pressure test accuracy of the anti-explosion membrane is improved.
Description
Technical field
The utility model relates to a kind of pressure testing device, relates in particular to a kind of blow-out disc pressure testing device.
Background technology
Blow-out disc is to be contained in pressure vessel top to prevent the metallic film of container explosion, is a kind of safety feature.When container inner pressure surpasses certain limit, film is first broken through, thereby can reduce the pressure in container, in order to avoid blast.The blow-out disc that the graphite devices such as graphite desorption tower are used need to be tested the resistance to compression of blow-out disc, guarantees that the blow-out disc of selecting can reach requirement.As shown in Figure 2, traditional blow-out disc pressure testing device is mainly a flange c9, and the lower internal diameter of flange c9 is less and be provided with air intake opening c10, and upper slice internal diameter is less than the external diameter that blow-out disc ring-type is rolled edge, is greater than the internal diameter that blow-out disc ring-type is rolled edge.Such design, in use, gas access from blow-out disc too close to, the impact of air-flow can strengthen the pressure to blow-out disc, causes the inaccurate of test result.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can eliminate pressure testing that air inlet impacts blow-out disc blow-out disc pressure testing device accurately.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A pressure testing device, is characterized in that:
Described blow-out disc pressure testing device comprises support, one-level cylinder, secondary cylinder and for clamping the flange a of blow-out disc;
Described one-level cylinder is airtight cylinder, and the downside of one-level cylinder has the air intake opening a being communicated with one-level cylinder, and side has the gas outlet being communicated with one-level cylinder; Secondary cylinder is the unlimited cylindrical drum cylinder in upper end, and downside has the air intake opening b being communicated with secondary cylinder; The gas outlet of described one-level cylinder is connected by flange b with the air intake opening b of secondary cylinder and one-level cylinder and secondary cylinder are all fixed on support;
Described flange a is arranged on the upper end of secondary cylinder, and the internal diameter of flange a is greater than the circular internal diameter of rolling edge of blow-out disc, is less than the circular external diameter of rolling edge of blow-out disc;
Described rain glass is arranged on secondary cylinder 3.
Adopt such technical scheme, blow-out disc pressure testing device of the present utility model is by the buffering of two cylinders, eliminated the impact of air-flow to blow-out disc, prevented that air-flow from producing additonal pressure to blow-out disc, improved the accuracy of blow-out disc pressure testing, the liquid that can also pass into heating simultaneously in blow-out disc pressure testing device replaces gas, can simulate better like this situation of graphite desorption tower inside, has further increased the accuracy of test.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of blow-out disc pressure testing device of the present utility model.
Fig. 2 is the schematic diagram of traditional blow-out disc pressure testing device.
Embodiment
As shown in Figure 1, blow-out disc pressure testing device of the present utility model comprise support 1, one-level cylinder 2, secondary cylinder 3, for clamping flange a4 and the rain glass 11 of blow-out disc.
One-level cylinder 2 is airtight cylinder, and the downside of one-level cylinder 2 has the air intake opening a7 being communicated with one-level cylinder 2, and side has the gas outlet 5 being communicated with one-level cylinder 2; Secondary cylinder 3 is the unlimited cylindrical drum cylinder in upper end, and downside has the air intake opening b6 being communicated with secondary cylinder 3.The gas outlet 5 of one-level cylinder 2 is connected by flange b8 with the air intake opening b6 of secondary cylinder 3 and one-level cylinder 2 and secondary cylinder 3 are all fixed on support 1.Gas is entered in one-level cylinder 2 and is cushioned by air intake opening a7 like this, then by gas outlet 5, from the air intake opening b6 of secondary cylinder 3, enter the blow-out disc that 3 couples of flange b8 of secondary cylinder clamp and carry out pressure testing, like this by the buffering of one-level cylinder 2 and secondary cylinder 3, avoid gas to cause extra pressure to the impact of blow-out disc, improved the accuracy of blow-out disc pressure testing.
Flange a4 is arranged on the upper end of secondary cylinder 3, and the internal diameter of flange a4 is greater than the circular internal diameter of rolling edge of blow-out disc, is less than the circular external diameter of rolling edge of blow-out disc.Rain glass 11 is arranged on secondary cylinder 3.Like this blow-out disc is clamped in flange a4, the size in flange a4 aperture is mated with the size of blow-out disc, and prevents blow-out disc to form support and cause pressure testing result inaccurate.Air pressure in rain glass 11 test secondary cylinders 3, draws the pressure bearing of blow-out disc with this.
Adopt such technical scheme, blow-out disc pressure testing device of the present utility model is by arranging two one-level cylinders 2 and secondary cylinder 3, during use, blow-out disc is clamped in flange a4, then the air intake opening a7 at one-level cylinder 2 passes into gases at high pressure, gases at high pressure enter in the air intake opening b6 of secondary cylinder 3 from gas outlet 5 after by the buffering of one-level cylinder 2, then in the interior continuous pressurization of secondary cylinder 3, blow-out disc are tested.By such design, by the design of one-level cylinder 2 and secondary cylinder 3, avoided gas directly blow-out disc to be impacted and produces extra pressure, improved like this accuracy of blow-out disc test.By such design, can also in pressure testing device, add the water of heating to replace air simultaneously, can simulate better the pressure condition in graphite desorption tower like this, further improve the accuracy of blow-out disc pressure testing.
