Description

Technical Field

[0001] This utility model belongs to the field of pressure vessel technology, specifically relating to a quick-release protective cover for pressure vessels. Background Technology

[0002] In industrial production and scientific research, pressure vessels are a common type of equipment widely used in chemical, petroleum, energy, and pharmaceutical industries. During operation, these vessels often require pressure relief devices to ensure safe operation due to internal media reactions or temperature changes. Pressure relief holes and internal pressure relief valves are important components of pressure vessels. Their function is to release excess pressure through the pressure relief valve when the pressure inside the vessel exceeds a set value, preventing the vessel from exploding or being damaged due to overpressure. To ensure safety during the pressure relief process and prevent high-pressure media from splashing out and injuring operators, a protective cover is usually installed on top of the pressure relief hole of the pressure vessel. For example, the existing patent with publication number CN207122753U discloses "A high-pressure cover. It consists of three parts: a protective cover, a combined gasket, and a high-pressure vessel cover. The middle part of the protective cover is the protective cover body, and a stud is provided in the lower middle part of the protective cover body. A splash guard is detachably provided on the lower outer side of the protective cover body." It can be seen that the application describes a common type of pressure vessel protective cover.

[0003] Currently, there are various types of pressure vessel protective covers on the market, among which the threaded tightening type is the most common. This type of installation involves rotating the protective cover to engage with the threads around the pressure relief hole, thereby achieving a tight fit. However, in actual use, the threaded tightening type requires operators to use tools to rotate and tighten it, which is relatively cumbersome and time-consuming. This inconvenience is particularly prominent when inspecting large pressure vessels or pressure relief holes located at high altitudes or in confined spaces. Furthermore, the threads are prone to wear and stripping due to frequent disassembly and improper operation, affecting the installation stability of the protective cover. Therefore, this utility model proposes a quick-release protective cover for pressure vessels. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release protective cover for pressure vessels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release protective cover for pressure vessels, comprising...

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 3 This is the first embodiment of the present invention, which provides a technical solution: a quick-release protective cover for a pressure vessel, comprising...

[0023] A cylindrical support column 6 is welded and fixed to the top surface of the pressure vessel cover 9 and located on one side of the pressure relief seat 91; a support seat 7 is movably sleeved on the surface of the cylindrical support column 6; a vertical plate 5 is fixed to the left side surface of the support seat 7; a base plate 4 is fixed to the top side of the vertical plate 5; a top cover 1 is installed at the bottom of the base plate 4 and located directly above the pressure relief seat 91; and a splash shield 2 is fixed to the bottom surface of the top cover 1 and covers the outside of the pressure relief seat 91. In actual use, due to the protection and obstruction of the top cover 1 and the splash shield 2, when the pressure relief valve 93 of the pressure relief channel 92 in the subsequent pressure relief seat 91 starts to depressurize, the depressurized gas will also be blocked by the splash shield 2 and will eventually splash towards the bottom of the splash shield 2, preventing the depressurized gas from splashing directly upward and causing unnecessary damage.

[0024] The structure 8, which is a limiting structure between the support 7 and the cylindrical support 6, includes a side lever 81 on the right side surface of the support 7 and a limiting rod 82 welded and fixed to the left side surface of the side lever 81. A limiting hole 83 corresponding to the limiting rod 82 is provided through the bottom surface of the cylindrical support 6. The left end of the limiting rod 82 passes through the limiting hole 83, providing stable limiting for the support 7. If the top cover 1 and the splash guard 2 need to be removed from the pressure relief seat 91, simply pull the side lever 81 to the side, causing the left end of the limiting rod 82 to... Once the end is removed from the limiting hole 83, the limiting of the support 7 can be quickly released. At this time, the support 7 can be slid towards the top of the cylindrical support 6 until the splash shield 2 can be moved up to the top of the pressure relief seat 91. Then, the support 7 can be rotated on the surface of the cylindrical support 6, and the top cover 1 and the splash shield 2 can be rotated and removed directly from the pressure relief seat 91, which facilitates the inspection and maintenance of the pressure relief seat 91. Alternatively, the support 7 can be slid up and down from the top of the cylindrical support 6 to achieve direct and quick disassembly of the top cover 1 and the splash shield 2.

[0025] In this embodiment, preferably, the limiting structure 8 further includes an inner groove 84 opened inside the bottom end of the cylindrical support column 6 and located at the bottom of the limiting hole 83, a spring 85 installed in the inner groove 84, and a semi-circular telescopic block 86. The surface of the limiting rod 82 is provided with a limiting groove 87 corresponding to the semi-circular telescopic block 86. The semi-circular telescopic block 86 is movably installed in the inner groove 84 by the spring 85, and the top of the semi-circular telescopic block 86 pops out into the limiting groove 87, which can engage and limit the limiting rod 82, ensuring the limiting stability of the limiting rod 82 on the support 7. If the end of the limiting rod 82 needs to be pulled out from the limiting hole 83 later, the side lever 81 is pulled forcefully to the side, so that the top of the semi-circular telescopic block 86 is gradually squeezed into the inner groove 84, and the left end of the limiting rod 82 can be smoothly pulled out from the limiting hole 83.

[0026] In this embodiment, preferably, the bottom end of the spring 85 is fixed to the inner wall of the bottom end of the inner groove 84, and the top end of the spring 85 is fixed to the semi-circular telescopic block 86.

[0027] In this embodiment, preferably, the inner wall of the top end of the inner groove 84 is provided with a pop-out hole that communicates with the limiting hole 83, and the pop-out hole corresponds to the semi-circular telescopic block 86, so that the top end of the semi-circular telescopic block 86 can be popped out smoothly and then squeezed in.

[0028] In this embodiment, preferably, a side hole is provided on the right side surface of the support 7 for the limiting rod 82 to pass through.

[0029] In this embodiment, preferably, the top end of the vertical plate 5 is welded and fixed to the base plate 4, and the bottom end of the vertical plate 5 is welded and fixed to the support 7.

[0030] Example 2

[0031] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that a top seat 3 is welded and fixed to the bottom surface of the substrate 4, and a threaded groove 31 is opened at the bottom of the top seat 3. A threaded post 11 matching the threaded groove 31 is welded and fixed to the top surface of the top cover 1, and the threaded post 11 is screwed into the threaded groove 31, so that the top cover 1 can be stably installed at the bottom of the substrate 4.

[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
