Description

Technical Field

[0001] The utility model relates to the technical field of safety pressure relief devices, in particular to a matrix-type monitoring gasket for a bursting disc device. Background Art

[0002] Bursting discs are a key safety feature of pressure vessels. When overpressure occurs in a pressure vessel, the disc rapidly ruptures to release the internal pressure, preventing further pressure buildup and potentially preventing explosion. However, in recent years, there have been instances of premature bursting of the disc even before the pressure vessel is overpressured, or failure to rupture and release the pressure due to overpressure. Subsequent technical analysis has shown that these are often due to improper installation of the disc, resulting in uneven or insufficient clamping force around the disc. Ultimately, this results in a failure to effectively restrain the disc, leading to its failure.

[0003] With the development of the national economy, the demand for bursting discs is increasing. However, it is difficult for bursting disc manufacturers to provide on-site installation instructions for every product. Although installation instructions are included with the product, operators often follow custom or experience during on-site installation. The wide variety of bursting discs, each with its own unique installation methods, can easily lead to installation problems and failures. Furthermore, some types of bursting discs maintain a good grip around the device when installed. However, over time, the gripping force around the disc becomes uneven or even insufficient, requiring the operator to continue pre-tightening the disc, otherwise the disc will not function properly.

[0004] Based on the above problems, it is urgent to design a monitoring device to monitor the real-time clamping status of the bursting disc. Utility Model Content

[0005] The purpose of the present invention is to provide a matrix monitoring gasket for a bursting disc device, so as to solve the problem in the prior art mentioned in the above background art that the real-time clamping state of the bursting disc cannot be monitored.

[0007] Preferably, two sealing gaskets are arranged in parallel above and below, an upper clamp and a lower clamp are arranged between the two sealing gaskets, and a bursting disc is clamped and fixed between the upper clamp and the lower clamp, an upper flange is arranged above the upper sealing gasket, and a lower flange is arranged below the lower sealing gasket, the upper flange and the lower flange are provided with aligned bolt holes on the same circumference, and the upper flange and the lower flange are connected into one by long bolts.

[0008] Preferably, a plurality of circular gasket through holes are evenly processed on the sealing gasket on the same circumference outside the circumference where the pressure sensor is located, and the long bolts can pass through the gasket through holes.

[0010] Preferably, the pressure sensor is a cylindrical structure and its height is the same as the thickness of the sealing gasket; the diameter of the pressure sensor shall not exceed one half of the width of the annular surface of the sealing gasket.

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to Figure 1-3 , Figure 1 This is a schematic diagram of the installation of the utility model; Figure 2 It is a top view of the sealing gasket; Figure 3 for Figure 2 Cross-sectional view of AA in the figure.

[0024] The utility model provides a matrix monitoring gasket for a bursting disc device, which is used to monitor the real-time clamping state of a clamped bursting disc; it comprises a sealing gasket 1 arranged in an annular shape, on which a plurality of pressure sensors 2 are uniformly embedded and arranged on the same circumference of the same axis, the pressure sensors 2 being cylindrical in structure and having a height the same as the thickness of the sealing gasket 1; a circular wire 3 is further embedded inside the sealing gasket 1, the circular wire 3 being surrounded by all the pressure sensors 2 and being connected to all the pressure sensors 2, the wire 3 An external wire 31 extends from the side of the sealing gasket 1, and the pressure sensor 2 is connected to the control room through the external wire 31; a plurality of circular gasket through holes 11 are evenly processed on the sealing gasket 1 on the same circumference outside the circumference where the pressure sensor 2 is located, and the number of the gasket through holes 11 is not greater than the number of the pressure sensors 2; the plurality of gasket through holes 11 can assist in positioning and installing the sealing gasket 1 to ensure the accuracy of the installation position of the pressure sensor 2, thereby ensuring that the data monitored by the pressure sensor 2 is more accurate.

[0025] The diameter of the pressure sensor 2 must not exceed half of the width of the annular surface of the sealing gasket 1 , otherwise the sealing performance of the sealing gasket 1 will be affected.

[0026] The wire 3 and the external wire 31 are both conductive copper wires with a wire diameter of no more than 1 mm. They are embedded in the interior of the sealing gasket 1, and the wire 3 is distributed in a ring shape; the external wire 31 is connected to the wire 3 and is led out in the middle position of the two gasket through holes 11 on the edge of the sealing gasket 1 and connected to the control room.

[0027] During clamping, two sealing gaskets 1 are arranged in parallel above and below, an upper clamper 4 and a lower clamper 5 are arranged between the two sealing gaskets 1, and a bursting disc 6 is clamped and fixed between the upper clamper 4 and the lower clamper 5, an upper flange 7 is arranged above the upper sealing gasket 1, and a lower flange 8 is arranged below the lower sealing gasket 1, and the upper flange 7 and the lower flange 8 are provided with bolt holes 71 aligned with the gasket through holes 11 on the same circumference, and long bolts 9 are used to connect the upper flange 7 and the lower flange 8 into one, and the bursting disc 6, the upper clamper 4, the lower clamper 5 and the two sealing gaskets 1 clamped and fixed between the upper flange 7 and the lower flange 8 are clamped and fixed.

[0028] The outer diameter of the sealing gasket 1 is equal to the outer diameters of the upper flange 7 and the lower flange 8 ; the inner diameter of the sealing gasket 1 is equal to the inner diameters of the upper clamp 4 , the lower clamp 5 , the upper flange 7 , and the lower flange 8 .

[0029] The pressure sensor 2 and the wire 3 are embedded in the interior of the sealing gasket 1 and bonded into a whole with silicone. They are placed between the upper flange 7 and the upper clamp 4, and between the lower flange 8 and the lower clamp 5. When the long bolt 9 is pre-tightened, the clamping force is transmitted to the inner side of the pressure sensor 2, thereby monitoring the status of the bursting disc 6 in real time.

[0030] The sealing gasket 1 is made of non-metallic flexible material and will deform to a certain extent after being subjected to the clamping force. Its thickness is 3mm to 5mm.

[0031] When the bursting disc 6 is monitored in real time, the size or uniformity of the clamping force of the upper flange 7 and the lower flange 8 is determined.

The circular ring wire surrounds all pressure sensors and connects them, realizing a compact layout and reducing space occupation. The pressure sensor and the wire are bonded into a whole by using silicone, which enhances the stability and durability of the structure. The external wire is led out through the through hole on the side of the sealing gasket, which is convenient for connecting to the control room and simplifies the installation and maintenance process. The inner and outer diameters of the sealing gasket match the corresponding dimensions of the flange and the clamp, ensuring the consistency and sealing of the overall structure. The through hole of the gasket allows long bolts to pass through, ensuring the fixation of the flange and the precise positioning of the pressure sensor. The sealing gasket is made of non-metallic flexible material with moderate thickness and can adapt to different working environments and pressure conditions.
