[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] Given that the existing pipe sealing devices, i.e. the cover body, are relatively complex in structure during installation, requiring multiple sets of protrusions for docking and engagement during assembly, the operation is inconvenient, affecting assembly efficiency, and the structural stability is also poor.
[0020] like Figure 1-4 As shown, this utility model embodiment provides a sealing device for the nozzle of a pressure vessel storage tank, including a fixing component 1: the fixing component 1 includes: an annular body 12 disposed on the outer side of the pressure vessel storage tank body 11; a through groove 121 symmetrically opened on the top of the annular body 12; a sealing cover 13 disposed on the top of the pressure vessel storage tank body 11; an insert rod 14 symmetrically disposed on the bottom of the sealing cover 13 and passing through the through groove 121; a connecting block 15 disposed on the bottom of the insert rod 14; a threaded groove 151 opened on the connecting block 15; a movable rod 16 disposed on the bottom of the connecting block 15; a groove 161 opened on the top of the movable rod 16 and hinged to the connecting block 15; and a screw 17 disposed on the bottom of the movable rod 16 and threadedly connected to the movable rod 16.
[0021] When the sealing cover 13 needs to be installed to seal the pressure vessel tank body 11, first move the sealing cover 13 to the top of the pressure vessel tank body 11 so that the movable rod 16 and the insert rod 14 pass through the through groove 121. Since the connecting block 15 is hinged to the groove 161 opened on the top of the movable rod 16, the movable rod 16 can be rotated to abut against the ring body 12. Then rotate the screw 17 threadedly connected to the movable rod 16 so that the screw 17 aligns with the threaded groove 151 opened on one side of the connecting block 15, which can fix the movable rod 16, thereby achieving the effect of fixing the sealing cover 13. When the sealing cover 13 needs to be disassembled later, simply rotate the screw 17 in the opposite direction to pull it out from the inside of the threaded groove 151, release the fixation of the movable rod 16, then stand the movable rod 16 upright, and then lift the sealing cover 13. This device has a simple structure, is easy to operate, and facilitates the disassembly and assembly of the sealing cover 13, making it more convenient to use.
[0022] Furthermore, an auxiliary component 2 is provided on the movable rod 16, the auxiliary component 2 including: an inclined groove 21 formed at the bottom of the movable rod 16.
[0023] A slanted groove 21 is made at the bottom of the movable rod 16. When the movable rod 16 passes through the through groove 121, the curvature of the slanted groove 21 makes it easier for the movable rod 16 to connect with the through groove 121.
[0024] Furthermore, the auxiliary component 2 also includes a stop lever 22 symmetrically arranged inside the groove 161.
[0025] A stop bar 22 is symmetrically arranged on opposite sides of the inner side of the groove 161. This allows the movable rod 16 to be limited when it is raised, making it easier for the movable rod 16 to reset and making it more convenient to use.
[0026] Furthermore, the stop lever 22 is a screw.
[0027] The stop lever 22 is set as a screw and threadedly connected to the movable rod 16. This allows the damaged stop lever 22 to be disassembled and replaced by screwing.
[0028] Furthermore, the auxiliary component 2 also includes a rubber pad 23 disposed on the inner side of the groove 161.
[0029] A rubber pad 23 is provided at the bottom inner side of the groove 161. This increases the friction and limits the movement of the movable rod 16, preventing it from shaking when the insertion rod 14 aligns with the through groove 121, thus making it more convenient to use.
[0030] Furthermore, the auxiliary component 2 also includes an anti-slip ring 24 disposed on the inner side of the through groove 121.
[0031] An anti-slip ring 24 is provided on the inner side wall of the through groove 121. Since the anti-slip ring 24 is made of rubber, this makes the connection between the through groove 121 and the insertion rod 14 more stable.
[0032] Furthermore, the auxiliary component 2 also includes a sealing ring 25 disposed on the inner side of the sealing cover 13.
[0033] A sealing ring 25 is provided on the inner wall of the sealing cover 13 to reduce the gap between the sealing cover 13 and the pressure vessel tank body 11, thereby increasing the sealing performance of the pressure vessel tank body 11.
[0034] Furthermore, the sealing cap 13 and the insertion rod 14 are bolted together.
[0035] The sealing cap 13 and the insert rod 14 are bolted together. This makes it easy to remove and replace the insert rod 14 if it is damaged or deformed in the future, so as not to affect the installation of the sealing cap 13.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
