[0029] Hereinafter, the preferred embodiments of the present utility model will be described in detail with reference to the drawings, and the present utility model will be further elaborated.

[0030] First, in combination with Figures 1 - 3The automatic plugging tool for explosion-proof valves according to the embodiment of the utility model is described, which is used for automatic plugging of explosion-proof valves and has a wide range of application scenarios.

[0031] like Figures 1 - 3 As shown, the automatic plugging tool for explosion-proof valves of the embodiment of the utility model comprises: a base 1, a sleeve 2, a piston module and an inflation module.

[0032] Specifically, Figures 1 - 3 As shown, in this embodiment, the top of the base 1 is open and the interior is hollow; the sleeve 2 is fixed at the top opening of the base 1, and the inner wall of the sleeve 2 is provided with an annular rubber pad 3, which is used to block the explosion-proof valve 4, and the material of the annular rubber pad 3 is polyurethane; the piston module is slidably arranged in the base 1; the piston module slides along the top of the base 1, squeezes the annular rubber pad 3, and magnetically opens the valve cover of the explosion-proof valve 4; the inflation module is arranged on the piston module and the base 1, and the inflation module is filled with gas into the explosion-proof valve 4. Through the sliding of the piston module and the coordinated work of the inflation module, the automatic blocking and inflation process of the explosion-proof valve 4 is realized, which reduces manual intervention and improves work efficiency and safety; the annular rubber pad is deformed and hugs the outer circle of the explosion-proof valve 4 under the extrusion of the piston module, so as to block the explosion-proof valve 4; the entire tooling structure is compactly designed, and the various components are closely matched, which is convenient for installation and disassembly, and reduces maintenance costs and time. In this embodiment, a sealing ring 21 may be provided on the top surface of the sleeve 2 to play a buffering role between the tooling and the explosion-proof valve 4, thereby protecting the product installed by the explosion-proof valve 4 from being scratched.

[0033] Further, if Figures 1 - 3 As shown, in this embodiment, the piston module includes: a piston 51, a magnet 52 and a driving air port 53; the piston 51 is slidably arranged in the base 1, and the outer wall of the piston 51 is slidably connected with the inner wall of the sleeve 2 and the inner wall of the base 1 through an O-ring 57, and the O-ring 57 can provide a reliable sealing effect to prevent gas from leaking from the gap between the piston 51 and the base 1 or the sleeve 2 during the sliding process of the piston 51; the magnet 52 is fixed on the top of the piston 51, and directly acts on the valve cover of the explosion-proof valve 4 through magnetic attraction. This non-mechanical contact opening method is more accurate and reliable, and avoids the wear and failure that may be caused by the traditional mechanical structure; the driving air port 53 is arranged on the base 1 and is connected to the inside of the base 1; the driving air port 53 is connected to an external air source, and the external air source can quickly provide power to drive the piston 51 and the magnet 52 close to the explosion-proof valve 4.

[0034] Further, if Figures 1 - 3As shown, in this embodiment, the piston module further includes: a guide rod 54 and a return spring 55; one end of the guide rod 54 is fixed to the piston 51, and the other end of the guide rod 54 passes through the sleeve 2 and can slide along the sleeve 2;; The return spring 55 is sleeved on the guide rod 54, and both ends of the return spring 55 are respectively abutted against the bottom of the sleeve 2 and the top of the piston 51, and the return spring 55 drives the piston 51 to reset. The guide rod 54 provides stable guidance for the sliding of the piston 51, ensuring the linearity and stability of the piston 51 during the sliding process; when the driving air source is disconnected, the return spring 55 can use its own elastic force to drive the piston 51 to reset, so that the piston 51 returns to its initial state.

[0035] Further, as Figures 1 - 3 shown, in this embodiment, an annular protrusion 56 is provided on the outer wall of the piston 51, and the annular protrusion 56 defines the sliding distance of the piston 51, so that the piston 51 can accurately reach a predetermined position during the movement; during the sliding of the piston 51, the annular protrusion 56 functions as a "stopper" to prevent the piston 51 from moving excessively due to external force or internal failure, which helps to protect the explosion-proof valve 4 and related components from damage and ensure the safe operation of the equipment.

[0036] Further, as Figures 1 - 3 shown, in this embodiment, the inflation module includes: an inflation port 61, an inflation channel 62 and a plurality of inclined holes 63; the inflation port 61 is arranged on the outer surface of the base 1 for inputting external test gas; the inflation channel 62 is connected to the inflation port 61 and extends into the piston 51 inside the base 1; a plurality of inclined holes 63 are inclinedly arranged in the piston 51, the inclined holes 63 are communicated with the inflation channel 62 and penetrate through the top of the piston 51 to ensure that the test gas can smoothly and evenly enter the explosion-proof valve 4.

[0037] Further, as Figures 1 - 3 shown, in this embodiment, a plurality of inclined holes 63 are arranged around the piston 51, and the connecting ends of the plurality of inclined holes 63 with the inflation channel 62 are located in the same plane, ensuring that the gas entering from the inflation channel 62 can be evenly dispersed in all directions of the piston 51. The number of the inclined holes 63 can be three, four, five, etc.

[0038] Further, as Figures 1 - 3 shown, in this embodiment, a connecting plate 7 is fixed to the bottom end of the base 1, and the connecting plate 7 connects to an external actuator load.

[0039] Before testing: The actuator load pushes the whole tooling to the explosion-proof valve 4 through the connected connecting plate 7, the driving air port 53 supplies driving air pressure, squeezes the annular rubber pad 3 to deform and tightly hold the outer circle of the explosion-proof valve 4 to form a seal, stops within the stroke L2, and at the same time the piston 51 drives the magnet 52 to approach the valve cover and suck it open. The test gas enters from the inflation port 61 and enters the inner cavity of the explosion-proof valve 4 through the four-equal-part inclined holes 63 for inflation.

[0040] After the test; after the product exhausts, the air intake at the driving air port 53 stops. After the entire tooling and the actuator are connected, they are in a static state. Under the action of the elastic force of the return spring 55 and the reaction force of the rubber pad returning to its original state, the piston 51 is pushed open to separate the magnet 52 from the valve cover, completing the separation of the magnet 52 and the valve cover.

[0041] As above, with reference to Figures 1 - 3 The explosion-proof valve automatic plugging tooling according to the embodiment of the present invention is described. It can complete inflation while plugging, and the separation of the valve cover and the magnet can be completed without the need for the end of high-efficiency automatic actuators such as manipulators to move.
