[0015] Compared with the prior art, this utility model provides a quick-opening door sealing structure for pressure vessels, which has the following advantages:

[0016] 1. Through the arrangement of the inner ring, exhaust plate, air inlet, air guide groove, inner groove, and exhaust port, the air inlet and air guide groove are set in the annular array at the bottom of the inner ring, which can uniformly receive high-pressure gas inside the pressure vessel from multiple directions, improving depressurization efficiency and stability. The inner groove on the side of the exhaust plate corresponds to the air guide groove at the bottom of the inner ring, ensuring that the gas can be accurately guided from inside the pressure vessel to the exhaust plate. This corresponding design makes the depressurization operation more precise and reliable. The exhaust port at the top of the exhaust plate is connected to the inner groove, providing a clear discharge channel for the high-pressure gas inside the pressure vessel, making the depressurization process smoother. The exhaust plate is rotatably connected to the inner ring. This design makes the operation more flexible and convenient. By rotating the exhaust plate, the air guide groove and the inner groove can be easily aligned or staggered, thereby controlling the opening and closing of the depressurization operation, improving the safety and controllability of the operation. At the same time, this rotatable connection method also facilitates maintenance and repair. The gas pressure inside the container is reduced through the exhaust port, which can quickly and effectively reduce the pressure inside the pressure vessel and ensure safe use.

[0017] 2. By incorporating an exhaust handle, limiting block, positioning block, and sliding groove, an exhaust handle is installed at the top of the inner ring, facilitating operation and improving ease of use. The bottom of the exhaust handle is rotatably connected to the inner ring, making operation more flexible and allowing easy rotation of the inner ring to align or offset the air guide groove with the inner groove, thereby controlling the pressure reduction operation. The limiting block at the top of the sealing cap positions the exhaust handle, ensuring accuracy and stability during operation. During operation, the exhaust handle can accurately stop at the required position, avoiding safety issues caused by misoperation. The positioning block at the top edge of the inner ring corresponds to the sliding groove at the top of the sealing cap. This design ensures the stability of the inner ring during rotation. The positioning block slides within the sliding groove, limiting the range of movement of the inner ring and preventing it from shifting or shaking during rotation, thus ensuring the smooth operation of the pressure reduction.

[0024] This utility model provides, for example Figure 1-4 The quick-opening door sealing structure of a pressure vessel shown includes a pressure vessel body 1;

[0025] A sealing cover 2 is provided on the outer side of the pressure vessel body 1. A fixing frame 5 is provided on the outer side of the pressure vessel body 1. A support arm 3 is provided on the outer side of the sealing cover 2. The sealing cover 2 and the pressure vessel body 1 are supported by the support arm 3 and the fixing frame 5. The support arm 3 and the fixing frame 5 are rotatably connected by a rotating shaft 4. A pin 8 is provided at the middle position between the support arm 3 and the sealing cover 2. The sealing cover 2 and the support arm 3 are rotatably connected by the pin 8. A sealing groove 10 is provided inside the pressure vessel body 1. A retaining ring 9 is provided on the outer side of the sealing groove 10. A retaining plate 12 is provided on the inner side of the sealing cover 2. The retaining plate 12 is engaged with the retaining ring 9. A sealing ring 13 is provided inside the sealing cover 2.

[0026] An inner ring 11 is provided at the bottom center of the sealing cover 2, and an exhaust plate 6 is provided inside the inner ring 11.

[0027] An air inlet 14 is provided in a ring array at the bottom of the inner ring 11, and an air guide groove 15 is provided at the bottom of the air inlet 14.

[0028] An inner groove 16 is provided on the side of the exhaust disc 6, and the inner groove 16 corresponds to the air guide groove 15.

[0029] An exhaust hole 7 is provided at the top of the exhaust plate 6, and the exhaust hole 7 is connected to the inner groove 16.

[0030] The exhaust plate 6 is rotatably connected to the inner ring 11, and the internal air pressure of the container is reduced through the exhaust port 7.

[0031] An exhaust handle 18 is provided at the top of the inner ring 11, and a limit block 17 is provided at the top of the sealing cover 2. The bottom of the exhaust handle 18 is rotatably connected to the inner ring 11, and the exhaust handle 18 is positioned by the limit block 17.

[0032] A positioning block 20 is provided at the top edge of the inner ring 11, and a groove 21 corresponding to the positioning block 20 is provided at the top of the sealing cover 2.

[0033] A rubber sleeve 19 is provided at the bottom outer side of the exhaust handle 18. The device can release air when the inner ring 11 is rotated by the exhaust handle 18 and the inner air guide groove 15 is aligned with the inner groove 16.

[0034] In this embodiment, the specific implementation steps of a quick-opening sealing structure for a pressure vessel are as follows: First, confirm that the sealing cover 2 is installed on the container. At this time, the air inlet 14, air guide groove 15, and inner groove 16 on the side of the exhaust plate 6 at the bottom of the inner ring 11 are misaligned, and the container is in a sealed state. When it is necessary to depressurize the container, hold the rubber sleeve 19 on the outside of the exhaust handle 18 and rotate the exhaust handle 18. The exhaust handle 18 drives the inner ring 11 to rotate, so that the positioning block 20 at the top edge of the inner ring 11 slides in the sliding groove 21 at the top of the sealing cover 2. Continue to rotate the exhaust handle. Rotate the exhaust handle 18 until the air guide groove 15 at the bottom of the inner ring 11 is aligned with the inner groove 16 on the side of the exhaust plate 6. At this time, the air pressure inside the container can enter the exhaust plate 6 through the air inlet 14, air guide groove 15, and inner groove 16, and be discharged from the exhaust hole 7 at the top of the exhaust plate 6 to achieve the pressure reduction operation. After the pressure reduction operation is completed, rotate the exhaust handle 18 again to make the air guide groove 15 and the inner groove 16 misaligned, and restore the sealed state of the container. The limiting block 17 at the top of the sealing cover 2 can position the exhaust handle 18 to ensure that the exhaust handle 18 can accurately stay in the required position during the operation.

[0035] like Figure 1-3 As shown, an inner ring 11 is provided at the bottom center of the sealing cap 2, an exhaust plate 6 is provided inside the inner ring 11, an air inlet 14 is arranged in a ring array at the bottom of the inner ring 11, an air guide groove 15 is provided at the bottom of the air inlet 14, an inner groove 16 is provided on the side of the exhaust plate 6, the inner groove 16 corresponds to the air guide groove 15, an exhaust hole 7 is provided at the top of the exhaust plate 6, the exhaust hole 7 is connected to the inner groove 16, the exhaust plate 6 is rotatably connected to the inner ring 11, and the internal air pressure of the container is reduced through the exhaust hole 7.

[0036] Preferably, the inner ring 11 is provided with an air inlet 14 and a guide groove 15 in a ring array at the bottom, which can uniformly receive high-pressure gas from the inside of the pressure vessel from multiple directions, improving the depressurization efficiency and stability. The inner groove 16 on the side of the exhaust plate 6 corresponds to the guide groove 15 at the bottom of the inner ring 11, ensuring that the gas can be accurately guided from the inside of the pressure vessel to the exhaust plate 6. This corresponding design makes the depressurization operation more precise and reliable. The exhaust hole 7 at the top of the exhaust plate 6 is connected to the inner groove 16, providing a clear discharge channel for the high-pressure gas inside the pressure vessel, making the depressurization process smoother. The exhaust plate 6 is rotatably connected to the inner ring 11. This design makes the operation more flexible and convenient. By rotating the exhaust plate 6, the guide groove 15 and the inner groove 16 can be easily aligned or staggered, thereby controlling the opening and closing of the depressurization operation, improving the safety and controllability of the operation. At the same time, this rotatable connection method is also convenient for maintenance and repair. The gas pressure inside the container is depressurized through the exhaust hole 7, which can quickly and effectively reduce the pressure inside the pressure vessel and ensure safe use.

[0037] like Figure 1 and Figure 4 As shown, an exhaust handle 18 is provided at the top of the inner ring 11, a limiting block 17 is provided at the top of the sealing cover 2, the bottom of the exhaust handle 18 is rotatably connected to the inner ring 11, the exhaust handle 18 is positioned by the limiting block 17, a positioning block 20 is provided at the top edge of the inner ring 11, and a sliding groove 21 corresponding to the positioning block 20 is provided at the top of the sealing cover 2.

[0038] Preferably, an exhaust handle 18 is provided at the top of the inner ring 11 to facilitate operation and improve ease of use. The bottom of the exhaust handle 18 is rotatably connected to the inner ring 11, making operation more flexible and allowing the inner ring 11 to rotate easily, aligning or offsetting the air guide groove 15 with the inner groove 16, thereby controlling the pressure reduction operation. The limiting block 17 provided at the top of the sealing cover 2 can position the exhaust handle 18 to ensure the accuracy and stability of the operation. During operation, the exhaust handle 18 can accurately stop at the required position, avoiding safety issues caused by misoperation. The positioning block 20 at the top edge of the inner ring 11 corresponds to the sliding groove 21 at the top of the sealing cover 2. This design can ensure the stability of the inner ring 11 during rotation. The positioning block 20 slides in the sliding groove 21, limiting the range of movement of the inner ring 11 and preventing the inner ring 11 from shifting or shaking during rotation, thereby ensuring the smooth operation of the pressure reduction.

[0039] like Figure 1-4 As shown, a rubber sleeve 19 is wrapped around the bottom outer side of the exhaust handle 18. The device can release air when the inner ring 11 is rotated by the exhaust handle 18 and the inner air guide groove 15 is aligned with the inner groove 16.

[0040] Optionally, a rubber sleeve 19 is provided around the bottom outer side of the exhaust handle 18. The rubber sleeve 19 has anti-slip and protective functions. During operation, the rubber sleeve 19 can increase friction, making it easier for the operator to grip the exhaust handle 18 and avoiding operational errors caused by slipping. At the same time, the rubber sleeve 19 can also protect the bottom of the exhaust handle 18 from wear and corrosion, extending its service life. The operation is simple and convenient by rotating the inner ring 11 of the exhaust handle 18. The operator only needs to rotate the exhaust handle 18 slightly to align or offset the air guide groove 15 with the inner groove 16, thereby controlling the pressure reduction operation. This design makes the operation more intuitive and convenient, improving work efficiency. When the inner air guide groove 15 is aligned with the inner groove 16, gas can be released. This design makes the gas release operation more accurate and reliable. The operator can judge whether the air guide groove 15 and the inner groove 16 are aligned by observing the position of the exhaust handle 18, thereby ensuring the accuracy of the gas release operation. At the same time, this design can also avoid safety problems such as gas leakage caused by misoperation.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
