Description

Technical Field

[0001] This utility model relates to the field of end cap technology, and in particular to a corrosion-resistant conical end cap. Background Technology

[0002] In many industrial sectors, such as petrochemicals, food processing, and pharmaceuticals, conical heads serve as key components of pressure vessels or piping systems, playing a vital role in sealing the ends, bearing internal pressure, and guiding the flow of media. In petrochemicals, conical heads are often installed at the bottom of reaction vessels and distillation towers to facilitate the collection and discharge of reaction products or residual materials.

[0003] The existing end caps are extremely cumbersome to install and position. During installation, bolts must be manually inserted into the corresponding bolt holes one by one. During this process, the tightness and evenness of the bolts must be constantly monitored, which consumes a lot of manpower and time. In addition, the fastening structure is prone to loosening due to vibration. Furthermore, the sealing structure of the end caps needs to be installed separately and cannot automatically adapt to seal.

[0004] Therefore, it is necessary to provide a corrosion-resistant conical head to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a corrosion-resistant conical end cap, which solves the problems of cumbersome installation and sealing structure in existing end caps.

[0006] To solve the above-mentioned technical problems, the present invention provides a corrosion-resistant conical head comprising: a head workpiece, a positioning limiting component installed at the bottom of the head workpiece for positioning the head workpiece, a protective sealing component sliding on the top of the positioning limiting component, an elastic sealing component installed on the inner wall of the protective sealing component, the protective sealing component cooperating with the elastic sealing component for structural sealing of the head workpiece, and adaptive locking components installed at both ends of the protective sealing component, the inner wall of the adaptive locking component being equipped with a dynamic limiting component.

[0007] Preferably, the positioning limiting component includes a limiting structure and a clamping block. The inner wall of the limiting structure has a slot structure for clamping the clamping block. The inner wall of the clamping block is equipped with a positioning rod.

[0008] Preferably, the protective sealing assembly includes a protective structure, a sealing structure installed on the inner wall of the protective structure, the sealing structure being used for sealing between the inner walls of the end cap workpiece, and a fixing block structure installed at the bottom of the protective structure, the fixing block structure being used for positioning and limiting the structural positioning of the assembly.

[0009] Preferably, the elastic sealing assembly includes a positioning seal, and each positioning seal has an elastic support installed on its inner wall, the elastic support being used for elastic support of the positioning seal.

[0010] Preferably, the adaptive locking assembly includes a locking block and a support frame. The locking block is installed on the inner walls of both ends of the protective sealing assembly. The inner wall of the support frame is equipped with a reverse-grooved structure. A fastening structure is provided in the middle of the support frame. A bevel gear structure is installed on the inner wall of the reverse-grooved structure and the fastening structure. The bevel gear structure is used for meshing transmission of the reverse-grooved structure. A driven member is threadedly connected to the inner wall of the reverse-grooved structure. The driven member is used for positional fastening of the locking block.

[0011] Preferably, the dynamic limiting component includes a limiting groove structure and a limiting baffle. The limiting groove structure is formed on the inner wall of the side end of the adaptive locking component. Limiting rod structures are installed at both ends of the limiting baffle. The limiting rod structures are used for the structural positioning of the adaptive locking component.

[0012] Compared with related technologies, the corrosion-resistant conical head provided by this utility model has the following beneficial effects: This invention provides a corrosion-resistant conical head. To improve installation convenience and sealing performance during use, the conical head utilizes a combination of an adaptive locking component and a dynamic limiting component. This allows for automatic adjustment based on the actual assembly position of the head and the cylinder, significantly simplifying the installation process and reducing reliance on operator skills. The dynamic limiting component restricts the head's displacement in real-time, preventing uneven stress caused by assembly deviations in traditional fastening structures. Furthermore, while the adaptive locking component is engaged, it simultaneously drives the protective sealing component to precisely engage with the inner wall of the positioning limiting component, eliminating the need for a separate sealing installation step. This ensures the sealing component remains aligned and fitted with the inner wall of the positioning limiting component throughout the installation process, preventing misalignment and tilting that can occur during manual installation.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of a corrosion-resistant conical head provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the positioning restriction component. Figure 3 for Figure 1 The diagram shows the structure of the positioning rod. Figure 4 for Figure 1 The diagram shows the structure of the positioning seal. Figure 5 for Figure 1 The diagram shows the structure of the protective sealing assembly. A corrosion-resistant conical head includes: a head workpiece 1, a positioning limiting component 2 installed at the bottom of the head workpiece 1 for positioning the head workpiece 1, a protective sealing component 3 slidingly mounted on the top of the positioning limiting component 2, an elastic sealing component 4 installed on the inner wall of the protective sealing component 3, the protective sealing component 3 cooperating with the elastic sealing component 4 for structural sealing of the head workpiece 1, and adaptive locking components 5 installed at both ends of the protective sealing component 3, with a dynamic limiting component 6 installed on the inner wall of the adaptive locking component 5.

[0017] The positioning and limiting component 2 includes a limiting structure 21 and a clamping block 22. The inner wall of the limiting structure 21 is provided with a slot structure 23, which is used to clamp the clamping block 22. A positioning rod 24 is installed on the inner wall of the clamping block 22.

[0018] When the end cap workpiece 1 is installed in position, the clamping blocks 22 on the inner walls at both ends can slide along the inner wall of the limiting structure 21. With continuous position sliding, the positioning rod 24 on the inner wall will automatically be restricted to the inner wall of the limiting structure 21 to ensure the pre-positioning of the end cap workpiece 1.

[0019] The positioning limiting component 2 includes, but is not limited to, annular slot type and guide rail slider type; in this embodiment, the positioning limiting component 2 is preferably annular slot type.

[0020] The protective sealing assembly 3 includes a protective structure 31, and a sealing structure 32 is installed on the inner wall of the protective structure 31. The sealing structure 32 is used for sealing between the inner walls of the end cap workpiece 1. A fixing block structure 33 is installed at the bottom of the protective structure 31. The fixing block structure 33 is used for positioning and limiting the structural positioning of the assembly 2.

[0021] When installing the structural seal on the end cap 1, the protective structures 31 at both ends can be slid directly onto the inner wall of the positioning and limiting component 2. When the protective structure 31 slides, the bottom fixed block structure 33 will automatically restrict the positioning and limiting component 2, reducing the loosening of the end cap 1. At the same time, the sealing structure 32 on the inner wall can seal the inner wall of the end cap 1.

[0022] The protective sealing component 3 includes, but is not limited to, lip seal type and combined gasket type; in this embodiment, the protective sealing component 3 is preferably a combined gasket type.

[0023] The elastic sealing assembly 4 includes a positioning seal 41, and each positioning seal 41 has an elastic support 42 installed on its inner wall. The elastic support 42 is used to provide elastic support for the positioning seal 41.

[0024] After the protective sealing assembly 3 is installed in position, the positioning seal 41 on the inner wall will be subjected to the elastic deformation of the elastic support 42. Under the elastic deformation of the structure, the positioning seal 41 can be tightly fitted to the inner wall of the end cap workpiece 1 to form a structural seal.

[0025] Among them, the elastic sealing component 4 includes, but is not limited to, rubber diaphragm type and spring-loaded type; in this embodiment, the elastic sealing component 4 is preferably spring-loaded type.

[0026] The adaptive locking assembly 5 includes a locking block 51 and a support frame 52. The locking block 51 is installed on the inner walls of both ends of the protective sealing assembly 3. The inner wall of the support frame 52 is equipped with a reverse-grooved structure 53. A fastening structure 54 is provided in the middle of the support frame 52. A bevel gear structure 55 is installed on the inner wall of the reverse-grooved structure 53 and the fastening structure 54. The bevel gear structure 55 is used for meshing transmission of the reverse-grooved structure 53. A driven member 56 is threadedly connected to the inner wall of the reverse-grooved structure 53. The driven member 56 is used for positional fastening of the locking block 51.

[0027] When the inner wall structure is locked and installed, the middle fastening structure 54 can be rotated first. Under the meshing connection of the end bevel gear structure 55, it can be transmitted to the inside of the reverse groove structure 53. When the reverse groove structure 53 rotates, the driven parts 56 at both ends will automatically lock onto the inner wall of the locking block 51 to ensure the locking and fixing of the structure.

[0028] The adaptive locking component 5 includes, but is not limited to, wedge block adaptive locking and mechanical limit adaptive locking; in this embodiment, the adaptive locking component 5 preferably uses mechanical limit adaptive locking.

[0029] The dynamic limiting component 6 includes a limiting groove structure 61 and a limiting baffle 62. The limiting groove structure 61 is formed on the inner wall of the side end of the adaptive locking component 5. The limiting baffle 62 is equipped with limiting rod structures 63 at both ends. The limiting rod structures 63 are used for the structural positioning of the adaptive locking component 5.

[0030] After the adaptive locking assembly 5 is installed and tightened, the limiting rod structure 63 on the inner wall of the limiting baffle 62 will automatically be positioned on the inner wall of the limiting groove structure 61 to form a positioning and locking of the structure, thereby reducing the loosening deviation of the structure.

[0031] The dynamic limiting component 6 includes, but is not limited to, a telescopic limiting mechanism and a limiting groove limiting mechanism; in this embodiment, the dynamic limiting component 6 is preferably a limiting groove limiting mechanism.

[0032] The working principle of the corrosion-resistant conical head provided by this utility model is as follows: During the installation and use of the conical head, firstly, the head workpiece 1 is slidably positioned inside the positioning and limiting component 2 for pre-positioning of the structure. Then, the protective sealing components 3 at both ends are slid onto the inner wall of the positioning and limiting component 2. When the protective sealing components 3 slide, the elastic sealing component 4 on the inner wall will cooperate with the protective sealing components 3 to form a position seal for the head workpiece 1, thereby reducing the corrosion caused by rainwater ingress. In addition, when the protective sealing components 3 slide, they will simultaneously limit the structure of the positioning and limiting component 2 for convenient installation. Subsequently, the structure of the protective sealing components 3 is locked by the adaptive locking components 5 on the inner walls at both ends. When the components are locked, the dynamic limiting component 6 on the inner wall will automatically position the structure to lock it in place, reducing installation deviation.

[0033] Compared with related technologies, the corrosion-resistant conical head provided by this utility model has the following beneficial effects: To improve installation convenience and sealing effect during the installation and use of the conical head, the adaptive locking component 5 and dynamic limiting component 6 work together to automatically adapt and adjust according to the actual assembly position of the head and the cylinder, greatly simplifying the installation process and reducing reliance on operator skills. The dynamic limiting component 6 can limit the displacement of the head in working conditions in real time, avoiding uneven local stress caused by assembly deviations in traditional fastening structures. In addition, while the adaptive locking component 5 is locking, it simultaneously drives the protective sealing component 3 to precisely engage with the inner wall of the positioning limiting component 2, eliminating the need for a separate sealing installation step. This ensures that the sealing component remains in close alignment with the inner wall of the positioning limiting component 2 throughout the installation process, avoiding the offset and skewing that easily occurs when manually installing seals.
