[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] Because positive pressure is applied inside the chamber of the pressure equipment, squeezing the sealing ring outwards, there is a risk that the sealing ring may detach from the groove. This invention addresses this by applying negative pressure to the back of the sealing ring before the sliding door opens, completely pulling the sealing ring back into the sealing groove and preventing it from detaching. The following describes how... Figures 1 to 5 This embodiment provides a detailed description of the sliding sealing door and automated pressure equipment.

[0040] Figure 1 A schematic diagram of the sliding sealing door provided in this embodiment is shown. Figure 2 An exploded view of the sliding sealing door provided in this embodiment is shown. Figure 3 A cross-sectional schematic diagram of the sliding sealing door provided in this embodiment is shown. Figure 4 It shows Figure 3 A magnified view of a portion of point A. (See diagram below.) Figures 1 to 4 As shown, the sliding sealing door provided in this embodiment is used to seal the sealing port 100 of an automated pressure equipment. The sealing door includes a sealing seat 1, a sealing ring 2, and a sealing door body 3. The sealing seat 1 is sleeved on the outer wall of the sealing port 100. A sealing groove 111 is formed on the side wall of the sealing seat 1 away from the sealing port 100 along the axial direction of the sealing port 100. An air hole 112 is formed on the bottom wall of the sealing groove 111. The sealing ring 2 is embedded in the sealing groove 111. The sealing door body 3 has a sealing wall 311 on the side close to the sealing port 100 along the axial direction of the sealing port 100. The sealing door body 3 can be connected to the sealing groove 111. The sealing position of the sealing wall 311 is switched between the sealing position and the open position of the sealing groove 111 away from the sealing wall 311. When the sealing door 3 is in the sealing position, the sealing seat 3 covers the sealing opening 100. The plug-in assembly 4 includes a first plug-in member 41 and a second plug-in member 42. The first plug-in member 41 has a plug-in hole 411 with the hole axis perpendicular to the axial direction of the sealing opening 100. The first plug-in member 41 is fixedly connected to the sealing door 3, and the second plug-in member 42 is fixedly connected to the sealing opening 100. When the sealing door 3 is in the sealing position, the second plug-in member 42 is inserted into the plug-in hole 411. It should be noted that the type of automated pressure equipment is not limited here. It can be a pressure oven or a degassing machine, or any equipment to be sealed with a sealing port 100, such as a sealing tank or a reaction vessel, as long as the equipment to be sealed has a sealing port 100 that needs to be sealed. The connection method between the sealing seat 1 and the sealing port 100 is not limited here. It can be a welded connection, or the sealing port 100 and the sealing seat 1 can be integrally formed, as long as the sealing seat 1 is fitted onto the outer wall of the sealing port 100.

[0041] The sealing door provided in this embodiment is fitted onto the outer wall of the sealing opening 100 via a sealing seat 1. A sealing groove 111 is formed on the side wall of the sealing seat 1 facing away from the sealing opening 100 along the axial direction of the sealing opening 100. An air hole 112 is formed on the bottom wall of the sealing groove 111. A sealing ring 2 is embedded in the sealing groove 111. The sealing door body 3 has a sealing wall 311 on the side of the sealing opening 100 along the axial direction of the sealing opening 100. When the sealing door body 3 is in the sealed position, the sealing groove 111 faces the sealing wall 311 and covers the sealing opening 100. Positive pressure is provided by inflating the sealing groove 111 through the air hole 112, causing the sealing ring 2 to compress the sealing wall 311, thereby sealing the sealing opening 100. When the sealing door 3 needs to be opened, the gas in the sealing groove 111 can be drawn out through the air hole 112 to provide negative pressure, so that the sealing ring 2 is adsorbed onto the bottom wall of the sealing groove 111, preventing the sealing ring 2 from detaching from the sealing groove 111, and then the sealing door 3 can be opened; the first plug-in 41 has a plug hole 411 with the hole axis perpendicular to the axial direction of the sealing port 100 and is fixedly connected to the sealing door 3, and the second plug-in 42 is fixedly connected to the sealing port 100. When the sealing door 3 is in the sealed position, the second plug-in 42 is inserted into the plug hole 411, thereby preventing the sealing door 3 from sliding relative to the sealing seat 1 when the sealing door 3 is in the sealed position, which would cause the sliding sealing door to fail.

[0042] In this embodiment, the second connector 42 is a spring positioning pin, which is fixedly connected to the sealing port 100. When the sealing door 3 is in the sealed position, the pin of the spring positioning pin is inserted into the insertion hole 411, thereby preventing the sealing door 3 from sliding relative to the sealing seat 1. When it is necessary to open the sliding sealing door to switch the sealing door 3 from the sealed position to the open position, the pin can be pushed out of the insertion hole 411 by pressing the pin of the spring positioning pin, so that the sealing door 3 and the sealing seat 1 can slide relative to each other.

[0043] Figure 5 It shows Figure 3 A magnified view of a portion at point B. (See diagram below.) Figures 2 to 5As shown, the sealing seat 1 includes a fixing ring 11 and a first connecting member 12. The inner sidewall of the fixing ring 11 is sleeved on the outer sidewall of the sealing opening 100. The sealing groove 111 is formed on the end face of the fixing ring 11 away from the sealing opening 100 along the axial direction of the sealing opening 100. The fixing ring 11 is detachably connected to the first connecting member 12. The sealing door body 3 includes a sealing cover 31 and a second connecting member 32. The sealing wall 311 is disposed on the end face of the sealing cover 31 close to the sealing opening 100 along the axial direction of the sealing opening 100. The sealing cover 31 is detachably connected to the second connecting member 32. 2. The first connector 41 is fixedly connected to the second connector 32 to cover the sealing opening 100. Thus, when the sealing door body 3 is in the sealing position, the sealing cover 31 is detachably connected to the second connector 32. This allows for the appropriate selection of the size of the sealing cover 31 and the fixing ring 11 based on the outer diameter of the sealing opening 100 for different outer diameters of the pressure equipment to be automated. This improves the adaptability of the sliding sealing door to the sealing opening 100 of the automated pressure equipment, making it suitable for sealing openings 100 with different outer diameters. It should be noted that the connection method between the first connector 12 and the fixing ring 11 is not limited here; it can be a threaded connection or a snap-fit ​​connection, as long as the first connector 12 and the fixing ring 11 can be detachably connected. Similarly, the connection method between the second connector 32 and the sealing cover 31 is not limited here; it can be a threaded connection or a snap-fit ​​connection, as long as the second connector 32 and the sealing cover 31 can be detachably connected.

[0044] Continue as Figures 2 to 5As shown, the first connector 12 has a first insertion groove 121 on the side wall of the outer side wall of the sealing port 100. The outer side wall of the fixing ring 11 is fixedly connected to the bottom wall of the first insertion groove 121. The second connector 32 has a second insertion groove 321 on the side wall of the outer side wall of the sealing port 100. The outer side wall of the sealing cover 31 is fixedly connected to the bottom wall of the second insertion groove 321. When the sealing door 3 is in the sealing position, the fixing ring 11 is inserted into the second insertion groove 321 and the sealing cover 31 is inserted into the first insertion groove 121. Thus, when the sealing cover 31 is in the sealing position and the sealing door is moved to seal the sealing port 100, it prevents the sealing door 3 and the sealing seat 1 from sliding relative to each other and moving along the axial direction of the sealing port 100, thereby causing sealing failure and improving the reliability of the sealing door sealing the sealing port 100. Specifically, the second insertion groove 321 includes a first receiving groove 3211 and a second receiving groove 3212. The groove depths of the first receiving groove 3211 and the second receiving groove 3212 are different. The outer wall of the sealing cover 31 is fixedly connected to the second receiving groove 3212. When the sealing door 3 is in the sealing position, the fixing ring 11 is inserted into the first receiving groove 3211, thereby distinguishing the installation positions of the fixing ring 11 and the first insertion groove 121 and the sealing cover 31 and the first insertion groove 121. This prevents the installation positions of the fixing ring 11 and the first insertion groove 121 and the sealing cover 31 and the second insertion groove 321 from being reversed, which would prevent the sealing cover 31 from being properly inserted into the first insertion groove 121 and reduce the assembly difficulty of the sealing seat 1.

[0045] Preferably, the outer wall of the sealing cover 31 extends with a first flange 312. When the sealing door 3 is in the sealed position, the first flange 312 is fixedly connected to the second receiving groove 3212, thereby improving the stability of the fixed connection between the sealing cover 31 and the second receiving groove 3212. Similarly, the outer wall of the fixing ring 11 extends with a second flange 113. When the sealing door 3 is in the sealed position, the second flange 113 is inserted into the first receiving groove 3211, thereby improving the insertion stability between the fixing ring 11 and the first receiving groove 3211.

[0046] like Figures 4 to 5As shown, at least two air holes 112 are spaced apart on the bottom wall of the sealing groove 111. This allows the sealing ring 2 to be evenly stressed when positive pressure is provided by filling the sealing groove 111 with air through the air holes 112, causing the sealing ring 2 to press against the sealing wall 311 and seal the sealing opening 100; or when negative pressure is provided by extracting gas from the sealing groove 111 through the air holes 112, causing the sealing ring 2 to adhere to the bottom wall of the sealing groove 111, and the sealing door 3 is opened. This prevents the sealing ring 2 from deforming and causing a decrease in sealing performance. It should be noted that the number of air holes 112 is not limited here; it can be two, three, four, five, or even more. Those skilled in the art can reasonably set the number according to actual needs, as long as the sealing ring 2 is evenly stressed and does not deform.

[0047] Preferably, a quick-connect fitting for the air tube is fixedly connected to the air hole 112, so that the air tube can be quickly inserted and removed, so that the air tube is connected to the air hole 112, thereby providing positive pressure for filling the sealing groove 111 or providing negative pressure for drawing air from the sealing groove 111, improving the ease of operation of the sliding sealing door.

[0048] like Figure 4 As shown, a sealing lip 21 is provided on the side of the sealing ring 2 facing the bottom wall of the sealing groove 111. When positive pressure is provided by filling the sealing groove 111 with air through the air hole 112, the sealing lip 21 can deform and squeeze the side wall of the sealing groove 111. This prevents the gas in the equipment to be sealed from leaking out of the equipment from the contact position between the sealing ring 2 and the side wall of the sealing groove 111, and increases the friction between the sealing ring 2 and the sealing groove 111, thereby improving the sealing effect of the sealing ring 2.

[0049] Preferably, the two sealing lips 21 are arranged radially spaced along the sealing ring 2, so that when air is injected into the sealing groove 111 through the air hole 112 to provide positive pressure, the two sealing lips 21 can deform simultaneously and squeeze the two sidewalls of the sealing groove 111 respectively, thereby further improving the sealing effect of the sealing ring 2.

[0050] This embodiment also provides an automated pressure device, including the above-mentioned sliding sealing door and sealing port 100, wherein the sealing door seals the sealing port 100.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
