Description

Technical Field

[0001] This utility model belongs to the field of flange protection, specifically a protective structure for flange sealing surfaces. Background Technology

[0002] In the field of industrial pipeline connections, the protective structure of the flange sealing surface is a key component to ensure the sealing performance, durability and safety of the flange connection;

[0003] Traditional protective plates are mostly fastened with bolts, which requires tools to operate one by one, which is time-consuming and laborious, especially in confined spaces or high-frequency maintenance scenarios. Chinese invention patent with announcement number CN110539970B discloses an externally fastened threaded locking flange sealing surface protection device, which includes multiple screws, cylindrical pins, cotter pins, snap handles, nuts and flange protective covers.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can prevent external debris from entering the pipe connected to the flange and causing pollution, and at the same time protect the flange cover, the protective cover is mostly fastened with bolts, which requires tools to operate one by one, which is time-consuming and laborious.

[0005] To address this issue, those skilled in the art have proposed a protective structure for the flange sealing surface to solve the problems raised in the background art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a protective structure for the flange sealing surface, which solves the problem that the existing technology uses bolt fastening, which requires tools to operate one by one, and is time-consuming and labor-intensive.

[0007] A protective structure for a flange sealing surface includes a flange body, a first protective plate, and a second protective plate. The first and second protective plates are provided with two sets of easily detachable connecting components and disassembly components on their sides. The connecting components include a positioning pin, a first fixing body, and a second fixing body. The first fixing body is provided with a mounting groove on its side, and a connecting spring is provided between the mounting groove and the side of the second fixing body.

[0008] The second protective plate has a first fixing groove on its side that is adapted to the size of the first fixing body, and a second locking groove on its side that is engaged with the second fixing body.

[0009] Through the above technical solution, the protective plate can be quickly installed and removed without tools by the synergistic effect of the connecting and disassembling components. The locking and engaging of the second fixing body and the second slot, combined with the quick ejection function of the top rod, significantly shortens the installation and disassembly time, making it particularly suitable for high-altitude or confined space operation scenarios.

[0010] Preferably, the disassembly assembly includes a reset block and a reset spring, one end of the reset spring is connected to the reset block, the other end of the reset spring is connected to the second protective plate, and the side of the reset block is slidably engaged with the second protective plate;

[0011] The reset block has a top rod connected to its side, which is adapted to the position of the second slot.

[0012] Preferably, a sealing gasket is provided between the flange body and the second protective plate, and a moisture-proof pad is connected to the side of the sealing gasket.

[0013] The above technical solution, through modular design, allows vulnerable parts such as protective plates and sealing gaskets to be replaced individually without the need for overall replacement, thus reducing maintenance costs.

[0014] Preferably, a sealing groove is provided on the side of the flange body, and a sealing strip adapted to the size of the sealing groove is provided on the side of the sealing gasket.

[0015] The above technical solution, through the composite design of sealing gasket and moisture-proof pad, combined with the embedded cooperation of sealing strip and sealing groove, forms a dual protection of physical sealing and moisture barrier, effectively preventing the intrusion of water vapor, dust and corrosive media.

[0016] Preferably, the first guard plate has two sets of threaded grooves on its side.

[0017] Preferably, the side of the locating pin is provided with a fixing bolt that is threadedly engaged with the threaded groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model achieves tool-free quick installation and removal of the protective plate through the synergistic effect of the connecting component and the disassembly component. The locking and engaging of the second fixing body and the second slot, combined with the quick ejection function of the top rod, significantly shortens the installation and removal time.

[0020] 2. This utility model uses a positioning pin and a threaded groove to be locked together by a fixing bolt, which can be adapted to flanges of different specifications and is suitable for flange sealing and protection needs in multiple fields.

[0021] 3. This utility model, through the composite design of sealing gasket and moisture-proof gasket, combined with the embedded cooperation of sealing strip and sealing groove, forms a dual protection of physical sealing and moisture barrier, effectively preventing the intrusion of water vapor, dust and corrosive media.
