Description

Technical Field

[0001] The utility model relates to the technical field of safety relief devices for pressure vessels, in particular to an integrated ultra-high pressure bursting disc relief device suitable for installation on an ultra-high pressure vessel. Background Art

[0002] With the continuous advancement of modern materials science and manufacturing technology, the design and manufacturing of pressure vessels have achieved rapid development. In recent years, pressure vessels have developed towards ultra-high pressure, extreme parameters, lightweight, and large capacity. The application of ultra-high pressure vessels above 100MPa is becoming increasingly widespread. They are indispensable key equipment in the modern manufacturing industry.

[0003] Due to the inherent characteristics of ultra-high-pressure vessels, their internal operating pressure is very high. When an emergency occurs in the equipment, the pressure and temperature inside the vessel change very quickly. To prevent overpressure explosions, a bursting disc safety relief device must be installed in the reactor. As the last safety barrier of ultra-high-pressure vessels, it plays a vital role. Existing bursting disc safety relief devices include a bursting disc and a clamp that clamps the edge of the bursting disc. This structure has the following problems: the sealing between the clamp and the bursting disc is difficult to control, which is not conducive to meeting the ultra-high-pressure pressure vessel operating requirements of small discharge diameter and fast discharge speed. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated ultra-high pressure bursting disc relief device with a reasonable structure and reliable use to solve the above-mentioned problems. Compared with existing bursting disc devices, the utility model can not only ensure ultra-high pressure but also break through the sealing limit. When the pressure difference on both sides of the bursting disc reaches a predetermined value at a set bursting temperature, the bursting disc will immediately operate, meeting the requirements of ultra-high pressure pressure vessel working conditions for a small relief diameter and a fast relief speed. At the same time, the utility model has a small size, is easy to install on the container, and ensures the container's service strength.

[0005] The technical solution of the utility model is:

[0006] An integrated ultra-high pressure bursting disc discharge device, the technical key points of which are: it consists of a tubular shell and a bursting disc located inside the tubular shell and integrally formed with the tubular shell. The bursting disc is a positive arch bursting disc, and the convex side of the bursting disc is provided with a cross groove.

[0007] In the above-mentioned integrated ultra-high pressure bursting disc relief device, the inner diameter of the tubular shell is 25mm to 32mm, and the wall thickness of the tubular shell is 4mm to 6mm.

[0008] In the above-mentioned integrated ultra-high pressure bursting disc relief device, the arch height of the bursting disc is 4mm to 7mm.

[0009] In the above-mentioned integrated ultra-high pressure bursting disc relief device, the depth of the cross-shaped groove is 1 mm to 2 mm.

[0010] In the above-mentioned integrated ultra-high pressure bursting disc relief device, the thickness of the bursting disc is 2mm to 3.5mm.

[0011] The beneficial effects of the utility model are:

[0012] 1. Compared with existing bursting disc devices, this device adopts an integrated structure and does not require a clamp to fix the bursting disc. It breaks through the sealing limitation and solves the sealing problem. It can be machined and formed from metal bars as raw materials. The external specifications and dimensions can be processed according to the actual needs of the pressure vessel. It has a simple structure and reliable strength. It does not require a forming process. The bursting disc that controls the internal pressure is directly processed and adjusted. The bursting pressure is adjusted by adjusting the arch height of the bursting disc and the depth of the cross groove to achieve the required bursting pressure. This device uses bursting discs to meet the requirements of ultra-high pressure vessel working conditions for small discharge diameter and fast discharge speed. It has good sealing performance, responds quickly under the set bursting pressure, and releases pressure quickly. It can effectively prevent the pressure-bearing equipment from being damaged by overpressure, ensuring the safe operation of ultra-high pressure vessels.

[0013] 2. Small size, easy to install on the pressure vessel, small opening, also ensures the use strength of the pressure vessel. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail according to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, the integrated ultra-high pressure bursting disc relief device comprises a tubular housing 1 and a bursting disc 2 integrally formed with the tubular housing 1 and located inside the tubular housing 1. The bursting disc 2 is a positive dome-shaped bursting disc with a cross-shaped groove 201 formed on the convex side of the bursting disc 2.

[0020] In this embodiment, the inner diameter of the tubular housing 1 is 25 mm to 32 mm, and the wall thickness of the tubular housing 1 is 4 mm to 6 mm. The arch height of the bursting disc 2 is 4 mm to 7 mm. The depth of the cross-shaped groove 201 is 1 mm to 2 mm. The thickness of the bursting disc 2 is 2 mm to 3.5 mm. The bursting disc 2 divides the tubular housing 1 into an outlet cavity and an inlet cavity.

[0021] During manufacture, the device is integrally formed from metal bar stock. The bar stock is machined using a lathe in the order of rough turning, semi-finishing, and finishing. The outlet and inlet cavities are machined according to the dimensions of the corresponding pressure vessel. The thickness and arch height of the bursting disc 2 are determined according to the bursting pressure, and the bursting disc 2 is machined. External surfaces requiring high precision are ground. Heat treatment is determined based on the actual bursting pressure. Parts requiring heat treatment should be completed before the cross groove 201 is machined. Finally, the cross groove 201 is machined using a milling machine or a metal engraving machine.

[0022] Working principle:

[0023] During use, this device is welded to a convenient opening in an ultra-high-pressure vessel, with the inlet cavity communicating with the interior of the pressure vessel. When the pressure differential across the bursting disc 2 reaches a predetermined value at the set bursting temperature of the ultra-high-pressure vessel, the disc 2 rapidly responds, rupturing along the weakened cross-shaped groove 201 to release pressure from the pressure vessel and prevent an explosion caused by overpressure.

[0024] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
