Description

Technical Field

[0001] This invention relates to the field of storage tank technology, specifically a sealing joint for storage tanks. Background Technology

[0002] Storage tanks, as the name suggests, are sealed containers used to store gaseous or liquid substances. They are essential infrastructure in various industries such as petroleum, chemical, and food. Depending on different usage requirements, materials used, and structural shapes, they come in a wide variety of types. Storage tanks are usually equipped with joints, which are the most indispensable accessories. They serve as connectors to connect the storage tank to other pipelines or equipment, enabling the transmission and distribution of liquid or gaseous substances within the tank.

[0003] The tank fittings used under the current technological background still have certain drawbacks, such as: 1. Existing tank joints are usually composed of two joint ends, consisting of a main joint that is fixedly connected to the tank and a secondary joint for connecting pipelines. However, when disconnecting the pipeline connection and disassembling the secondary joint, a valve is usually installed on the main joint for sealing after disassembly. This cannot achieve automatic sealing of the main joint, affecting the convenience of operation and failing to meet the needs of quick assembly and disassembly of the joint and quick connection or disconnection. 2. In the existing tank joints, the main joint and the auxiliary joint are connected by threads. In terms of operation, this is not convenient enough and cannot achieve quick and easy disassembly and assembly of the joint. In addition, after the main joint and the auxiliary joint are connected, they cannot meet the purpose of multi-level sealing treatment, which affects the reliability of the seal. Therefore, we propose a sealed joint for storage tanks to solve the problems mentioned above. Summary of the Invention

The middle part of the limiting seat cover is connected to the linkage column in a sliding manner.

[0009] Preferably, a first sealing ring is fixedly snapped onto the right end of the narrow portion of the sealing member, and the first sealing ring presses against and seals the connection between the narrow portion cavity of the wide portion of the main pipe seat and the narrow portion cavity of the main pipe seat. A second sealing ring is fixedly snapped onto the connection between the narrow portion and the wide portion of the sealing member, and the second sealing ring presses against and seals the connection between the wide portion cavity of the wide portion of the main pipe seat and the narrow portion cavity. The gap between the first and second sealing rings corresponds to the opening at the right end of the flow channel groove.

[0010] Preferably, the auxiliary connector assembly includes an auxiliary tube seat, a pusher column, and an auxiliary tube sleeve. The left end of the auxiliary tube seat is sleeved on the outside of the narrow part of the main tube seat, and the left end of the auxiliary tube seat is inserted into the cavity of the main tube sleeve. An integrated pusher column is provided in the middle of the cavity of the auxiliary tube seat, and the pusher column is movably inserted into the cavity of the narrow part of the main tube seat. The cylindrical part of the pusher column is inserted into the cavity of the central tube of the sealing component. An integrated auxiliary tube sleeve is provided on the outside of the left section of the auxiliary tube seat, and the left end of the auxiliary tube sleeve is sleeved on the outside of the main tube sleeve. The outer side of the right section of the sub-tube seat is slidably connected to a locating ring, and a second spring is installed at the connection between the locating ring and the sub-tube seat.

[0012] Preferably, a fifth sealing ring is fixedly engaged on the left side wall of the push column, and the fifth sealing ring presses against and seals the right side wall of the sealing member. The upper and lower sides of the cylindrical part of the push column are provided with an integrated second pin part, and the second pin part forms a sliding structure in the spiral groove.

[0013] Preferably, the inner ring wall of the dial ring is recessed inward and an auxiliary groove is provided, and the left side wall of the auxiliary groove is inclined, and the inclined groove wall in the auxiliary groove is pressed and fitted against the pressure plate end of the locking component. In this locking component, the hook end is connected to the outer wall of the narrow part of the main seat by a snap-fit ​​mechanism.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the storage tank uses a sealed joint, which can achieve automated sealing after disassembly and separation, and can achieve automatic locking after automatic sealing, effectively preventing accidental opening and leakage of the storage tank. In addition, the staggered snap-fit ​​method can meet the use requirements of multi-level sealing treatment and effectively ensure the reliability of sealing. 1. The main pipe seat has a wide section and a sealing component. After the sealing component loses the push of the push column, it resets by the elastic deformation of the first spring. The sealing component and the connecting column slide back and forth in the cavity of the wide section of the main pipe seat. With the pressure of the tank body pushing the connecting column, the narrow section of the sealing component and the first sealing ring are inserted and stuck in the cavity of the narrow section of the wide section of the main pipe seat, and the wide section of the sealing component and the second sealing ring are inserted and stuck in the cavity of the wide section of the wide section of the main pipe seat. Through the sealing treatment of the flow channel groove opening by the first sealing ring and the second sealing ring, the auxiliary connector assembly can be disassembled and separated to realize the automatic sealing treatment of the main connector assembly. There is no need to cooperate with the valve for sealing treatment. The auxiliary connector can be quickly connected or disconnected, ensuring the ease of operation. Furthermore, by utilizing the compression elastic deformation reset and the twisting elastic deformation reset of the first spring, the sealing component is sequentially driven to reset and slide within the cavity of the main pipe seat and to reset and rotate on the linkage column. When the sealing component resets and slides, the first pin follows the transverse groove in the "L"-shaped groove. When the sealing component resets and rotates, the first pin follows the longitudinal groove in the "L"-shaped groove. By restricting the first pin through the longitudinal groove in the "L"-shaped groove, the sealing component achieves automatic locking operation after completing the sealing process. In actual use, this effectively prevents accidental opening that could lead to tank leakage and reduces safety hazards during tank use. Furthermore, through the sliding fit between the second pin and the spiral groove, when the auxiliary connector assembly is docked onto the main connector assembly, the pushing column pushes the sealing component, causing the sealing component to rotate on the connecting column, and causing the sealing component and the connecting column to slide in the cavity of the main pipe seat. Through the setting of the linkage structure, the automatic opening operation of the sealing component is realized during the docking process, which optimizes the operation steps of the connector docking and achieves the purpose of simple operation. 2. It is equipped with a narrow section of the main pipe seat and a secondary pipe seat. When the secondary connector assembly is connected to the main connector assembly, the secondary pipe seat with the fourth sealing ring is inserted into the cavity of the main pipe sleeve and presses against the cavity wall of the main pipe sleeve. The secondary pipe seat with the third sealing ring is fitted onto the narrow section of the main pipe seat and presses against the right side wall of the narrow section of the main pipe seat. The push column with the fifth sealing ring presses against the right side wall of the sealing component. The staggered snap-fit ​​method meets the application requirements of multi-layer sealing treatment, which is different from the existing single-layer sealing method and effectively ensures the reliability of sealing. Furthermore, after the auxiliary connector assembly is connected to the main connector assembly, the auxiliary pipe seat is fitted onto the narrow part of the main pipe seat. The elastic deformation and reset of the torsion spring causes the locking element to automatically flip on the pipe wall of the auxiliary pipe seat, and the hook end of the locking element engages with the outer wall of the narrow part of the main pipe seat, realizing the automatic locking operation after docking and installation, and assisting in the purpose of quick assembly and disassembly of the connector.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-13 The present invention provides a technical solution: a sealing joint for a storage tank, including a storage tank body 1, and also including a main joint assembly 2 and a secondary joint assembly 3.

[0019] The storage tank uses a sealed joint that needs to be installed before use, according to the attached... Figure 1 , Figure 2 and Figure 3 As shown, an integrated flange port is provided at the outlet of the storage tank body 1, wherein the cavity of the flange port is connected to the tank cavity. Since the outer wall of the main pipe seat 4 is provided with an integrated flange, the center of the flange coincides with the center of the main pipe seat 4. After the main connector assembly 2 is installed, it is inserted into the cavity of the flange port in the storage tank body 1 in a horizontal state. That is, after the main pipe seat 4 is installed, it is inserted into and locked in the cavity of the flange port in the storage tank body 1. The flange is attached and fixed to the flange body of the flange port in the storage tank body 1 by bolts. Since a rubber sealing gasket is snapped onto the flange of the flange port in the tank body 1, after the main pipe seat width 4 is installed, the flange and the flange port in the tank body 1 are sealed by the rubber sealing gasket, thus completing the fixed installation of the main connector assembly 2 on the tank body 1. Since the auxiliary pipe seat 9 has an integrated connecting pipe section horizontally to the right in the middle right side, the auxiliary connector assembly 3 is connected and fixed together with the external pipe at the end opposite to the main connector assembly 2. That is, the connecting pipe section in the auxiliary pipe seat 9 is used for the fixed connection of the external pipe, thus completing the fixed installation operation of the auxiliary connector assembly 3 on the external pipe. The storage tank uses a sealed connector for merging and docking operations during use. The auxiliary connector assembly 3 is connected to the main connector assembly 2 via a plug-in method, enabling convenient automatic locking after plug-in installation. It also features a multi-layered sealing system to ensure reliable sealing. Specifically, refer to the attached... Figure 2 , Figure 3 , Figure 6 and Figure 11As shown, the narrow section 5 of the main pipe seat is integrally structured and located in the middle right side of the wide section 4 of the main pipe seat. It is horizontally positioned to the right on the right side of the wide section 4 of the main pipe seat, with their centers overlapping. The narrow section 5 of the main pipe seat and the wide section 4 of the main pipe seat combine to form a complete main pipe seat for the main connector assembly 2. Since the cavity of the narrow section 5 of the main pipe seat is a conical structure with a larger left side and a smaller right side, and since the pusher 10 is integrally structured and located in the middle of the cavity of the secondary pipe seat 9, and is horizontally positioned to the left, it is co-centered with the secondary pipe seat 9. The pusher 10 is a conical structure with a larger left side and a smaller right side. The diameter of its left end is smaller than the diameter of the right end of the cavity in the narrow section 5 of the main pipe seat. When the secondary connector assembly 3 is initially joined and connected to the main connector assembly 2, the left end of the secondary pipe seat 9 is sleeved on the outside of the narrow section 5 of the main pipe seat, and the left end of the pusher 10 is movably inserted into the cavity of the narrow section 5 of the main pipe seat. Because an integrated main pipe sleeve 501 is provided on the outer side of the left end of the narrow section 5 of the main pipe seat, the main pipe sleeve 501 is positioned horizontally to the right and is fitted onto the outer side of the narrow section 5 of the main pipe seat. The two are co-centered, and its outer longitudinal section has a polyhedral prism structure. Similarly, because an integrated secondary pipe sleeve 11 is provided on the outer side of the left section of the secondary pipe seat 9, the secondary pipe sleeve 11 is positioned horizontally to the left and is fitted onto the outer side of the secondary pipe seat 9. The two are co-centered, and its longitudinal section has a polyhedral prism structure, which matches the main pipe sleeve 501. When the secondary connector assembly 3 continuously merges and connects to the main connector assembly 2... The auxiliary tube seat 9 is driven to move, causing it to slide and connect continuously on the narrow part 5 of the main tube seat, and the pusher 10 is continuously pushed and displaced within the cavity of the narrow part 5 of the main tube seat. After the auxiliary tube seat 9 is continuously driven, the left end of the auxiliary tube seat 9 is inserted into the cavity of the main tube sleeve 501, and the left end of the auxiliary tube sleeve 11 is sleeved on the outside of the main tube sleeve 501. The right end of the narrow part 5 of the main tube seat is inserted into the cavity of the auxiliary tube seat 9. That is, the left end of the auxiliary tube seat 9 is inserted into the reserved gap between the main tube sleeve 501 and the narrow part 5 of the main tube seat, and the right end of the main tube sleeve 501 is inserted into the reserved gap between the auxiliary tube sleeve 11 and the auxiliary tube seat 9. When the secondary tube sleeve 11 is sleeved and connected to the main tube sleeve 501, the secondary tube sleeve 11 is positioned in a movable position on the main tube sleeve 501 after docking due to the polyhedral prism structure. This limits the secondary tube seat 9 and prevents it from rotating and causing the push column 10 to deflect, so that the second pin 1002 corresponds to the opening of the straight groove in the spiral groove 602. According to the appendix Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the pusher 10 has an integrated cylindrical part horizontally to the left in the middle of its left side. The upper and lower sides of the cylindrical part are vertically provided with an integrated second pin part 1002. The sealing part 6 has an integrated shaft tube part horizontally to the left in the middle of its cavity. The shaft tube part is co-centered with the sealing part, and the right end of the shaft tube part is open. The upper and lower sides of the shaft tube part in the sealing part 6 are provided with spiral grooves 602. The right end of the spiral groove 602 extends to the right and is provided with an open straight groove. The straight groove is horizontal. When the auxiliary connector assembly 3 is continuously connected to the main connector assembly 2, the pusher 10 is continuously pushed into the cavity of the narrow part 5 of the main pipe seat, so that the cylindrical part of the pusher 10 is inserted into the cavity of the shaft tube part in the sealing part 6, and the second pin part 1002 is movably locked into the straight groove in the spiral groove 602. Since the spiral angle of the spiral groove 602 is ninety degrees, the upper and lower spiral grooves 602 are arranged in opposite directions. Since the spiral groove 602 is connected to the second pin 1002 by a movable locking method, after the push column 10 is continuously pushed into the cavity of the narrow part 5 of the main pipe seat, the second pin 1002 slides in the spiral groove 602. Through the sliding cooperation between the two, the sealing member 6 is driven to rotate. Because the sealing component 6 has a dome-shaped structure, a first bearing is fixedly sleeved on the outer side of the right end of the shaft tube, and a second bearing is also fixedly snapped onto the left side wall. Furthermore, an integrated shaft column is horizontally positioned to the right in the middle of the groove of the connecting column 7, with the shaft column being concentric with the sealing component. The end of the shaft column is snapped onto and fixedly connected to a limit plate with bolts. After the connecting column 7 is installed, its right section is movably inserted into the cavity of the sealing component 6, and the end of the right section is connected to the sealing component via the first bearing. The six-phase rotating connection, after the linkage column 7 is installed, its right column body is also movably sleeved on the central shaft tube of the sealing component 6, wherein the central shaft tube is movably inserted into the cavity of the central shaft tube of the sealing component 6, and the central shaft tube is rotatably connected to the central shaft tube of the sealing component 6 through the second bearing, and the central shaft tube, together with the limiting plate, is movably locked in the cavity of the central shaft tube of the sealing component 6, so that the sealing component 6 is positioned on the linkage column 7 in a movable state, and the sealing component 6 rotates at the right end of the linkage column 7 with the assistance of its central shaft tube after being driven; Because a rubber sealing ring is provided at the connection between the outer side of the right section of the linkage column 7 and the cavity wall of the sealing component 6, and a rubber sealing ring is also provided at the connection between the tube groove wall and the outer tube wall of the shaft tube in the sealing component 6, the connection between the two is sealed by the rubber sealing ring. Since the limiting seat cover 402 is installed and snapped into place and fixed to the left side of the main pipe seat width 4 by bolts, it blocks the left cavity opening of the wide section of the main pipe seat 4. Since the longitudinal section of the linkage column 7 is set in a "T" shape, and the longitudinal section of the left column is set in a polyhedral prism structure, the linkage column 7 is installed and moves through the middle of the limiting seat cover 402, so that the linkage column 7 is positioned on the limiting seat cover 402 in a movable state. That is, the linkage column 7 and the sealing member 6 form a synchronous sliding structure, but the linkage column 7 and the sealing member 6 do not form a synchronous rotation structure. Since a first spring 8 is installed at the connection between the sealing component 6 and the limiting seat cover 402, the first spring 8 is movably sleeved on the outside of the linkage column 7 after it is installed. One end of the first spring 8 is inserted into the spring chamber in the sealing component 6 and is fixedly connected to the chamber wall by bolts. The other end of the first spring 8 is inserted into the spring chamber in the limiting seat cover 402 and is fixedly connected to the chamber wall by bolts. When the sealing component 6 is driven to rotate, the first spring 8 undergoes elastic deformation due to the twisting force. Because "L"-shaped grooves 403 are provided on both the upper and lower walls of the wide section of the main pipe seat 4, the "L"-shaped grooves 403 are divided into longitudinal grooves and transverse grooves. The upper and lower "L"-shaped grooves 403 are arranged in opposite directions. The longitudinal groove in the "L"-shaped groove 403 is arranged in an arc shape, with an arc dimension of ninety degrees. The arc center of the longitudinal groove coincides with the pipe center of the wide section of the main pipe seat 4. Furthermore, because the upper and lower sides of the wide section of the sealing component 6 are provided with an integrated structure... The first pin portion 601 is vertically arranged and is movably inserted into the "L"-shaped groove 403. When the sealing member 6 is driven to rotate, the first pin portion 601 slides in the longitudinal groove of the "L"-shaped groove 403. After the sealing member 6 is driven to rotate, the first pin portion 601 slides to the connection between the longitudinal groove and the transverse groove in the "L"-shaped groove 403, so that the longitudinal groove in the "L"-shaped groove 403 loses its limiting effect on the first pin portion 601, and the unlocking process of the sealing member 6 is completed. Because the transverse channel in the "L"-shaped groove 403 is set horizontally to the left, and the left end of the transverse channel is set in an open state, and the length of the transverse channel is greater than the maximum sliding distance of the sealing member 6, the pushing column 10 continues to push into the cavity of the narrow part 5 of the main pipe seat. After the sealing member 6 is unlocked, the sealing member 6 moves synchronously under the push of the pushing column 10, so that the sealing member 6 slides in the cavity of the wide part 4 of the main pipe seat, and the first pin part 601 slides along the transverse channel in the "L"-shaped groove 403. When the sealing member 6 is pushed and slid, the connecting column 7 slides in the middle of the limiting seat cover 402, and the first spring 8 is further subjected to the squeezing force and undergoes elastic deformation. According to the appendix Figure 2 , Figure 3 , Figure 9 and Figure 13As shown, since a third sealing ring 901 is fixedly snapped onto the right side cavity wall of the secondary tube seat 9, and a fourth sealing ring 902 is fixedly snapped onto the left end of the secondary tube seat 9, after the secondary connector assembly 3 is joined and connected to the main connector assembly 2, the left end of the secondary tube seat 9 is completely inserted into the cavity of the main tube sleeve 501. The fourth sealing ring 902 is sleeved on the outside of the narrow part 5 of the main tube seat, and it presses against and seals the cavity wall of the main tube sleeve 501, performing a first layer of sealing treatment after docking. The right end of the narrow part 5 of the main tube seat is completely inserted into the cavity of the secondary tube seat 9, and the third sealing ring 901 is snapped onto the right side wall of the narrow part 5 of the main tube seat, and it presses against and seals the right side wall of the narrow part 5 of the main tube seat, performing a second layer of sealing treatment after docking. Since the fifth sealing ring 1001 is fixedly attached to the left side wall of the push column 10, after the auxiliary connector assembly 3 is joined and connected to the main connector assembly 2, the left side wall of the push column 10 is in contact with the right side wall of the sealing component 6. The fifth sealing ring 1001 is covered on the outside of the cavity opening of the central tube of the sealing component 6, and is engaged with the right side wall of the sealing component 6, in a pressure sealing state, and performs three-layer sealing treatment after docking. According to the appendix Figure 2 , Figure 3 , Figure 11 , Figure 12 and Figure 13 As shown, the left end of the locking component 14 is the hook end, and the right end is the pressure plate end. They are arranged in a circular array with the center of the secondary tube seat 9 as the center. Since the middle of the locking component 14 is rotatably connected to a shaft, it is movably locked within the groove of the tube wall of the secondary tube seat 9 after installation. The shaft is inserted into the groove wall, and the hook end extends into the tube cavity of the secondary tube seat 9, while the pressure plate end extends to the outside of the secondary tube seat 9. Furthermore, a torsion spring 15 is installed at the connection between the locking component 14 and the secondary tube seat 9. After installation, the torsion spring 15 is movably sleeved on the central shaft of the locking component 14. On the column, one end is snapped onto the locking member 14, and the other end is snapped onto the groove wall of the secondary tube seat 9. After the secondary connector assembly 3 merges and docks with the main connector assembly 2, the secondary tube seat 9 completes docking on the narrow part 5 of the main tube seat. The elastic deformation and reset of the torsion spring 15 causes the locking member 14 to reset and flip on the tube wall of the secondary tube seat 9, and the hook end of the locking member 14 engages with the outer seat wall of the narrow part 5 of the main tube seat, locking the secondary tube seat 9, thus completing the self-locking after docking between the secondary connector assembly 3 and the main connector assembly 2. The storage tank uses a sealed joint, and according to the attached... Figure 4 , Figure 5 , Figure 7 and Figure 12As shown, the longitudinal section of the main pipe seat width 4 is set in a "convex" shape, and is divided into two parts from left to right: a wide section and a narrow section. Since the longitudinal section of the sealing member 6 is set in a "convex" shape, it is adapted to the seat cavity of the main pipe seat width 4. After the sealing member 6 is installed, the narrow section is movably inserted into the narrow section cavity of the main pipe seat width 4, and the wide section is movably inserted into the wide section cavity of the main pipe seat width 4. The auxiliary connector assembly 3 is joined and connected to the main connector assembly 2. After the sealing member 6 is pushed and slid by the push column 10, the first sealing ring 603 loses its blocking effect on the right end opening of the flow channel groove 401. That is, the first sealing ring 603 is placed on the left side of the opening in the flow channel groove 401, and the left side is sealed to keep the opening in the flow channel groove 401 in an open state. Because the limiting seat cover 402 has flow ports at equal intervals, and the flow ports are arranged in a ring array with the center of the ring as the center, each flow port is arranged in a one-to-one correspondence with each flow channel 401. Also, because the main pipe seat width portion 4 has flow channel 401 in the seat wall, the flow channel 401 is arranged in a ring array with the center of the main pipe seat width portion 4 as the center, and both its left and right ends are open. Its right end extends to the cavity wall of the narrow part of the main pipe seat width portion 4 and is connected to the narrow part of the cavity. Its left end is connected to the flow port in the limiting seat cover 402. The material in the tank body 1 passes through the flow port in the limiting seat cover 402 and the flow channel 401 in sequence and enters the narrow part of the main pipe seat width portion 4. The seat cavity of the narrow part of the main pipe seat 5 is connected to the seat cavity of the main pipe seat width portion 4 and enters the seat cavity of the narrow part of the main pipe seat 5. Since the pusher 10 is adapted to the cavity of the main pipe seat 5, after the pusher 10 is connected, a gap is reserved between it and the cavity wall of the main pipe seat 5 to form a flow channel. After the material in the tank body 1 enters the cavity of the main pipe seat 5, it enters the flow channel between the main pipe seat 5 and the pusher 10. Since the auxiliary pipe seat 9 has flow ports at equal intervals on the right cavity wall, the flow ports are arranged in a ring array with its center as the center. The flow ports are used to connect the cavity in the auxiliary pipe seat 9 and the cavity in the connecting pipe section. The material enters the connecting pipe section through the flow port in the auxiliary pipe seat 9 and is then transported through the external pipeline. The storage tank uses a sealed connector for disassembly and separation after use. The main connector assembly 2 is fixedly installed at the flange connection port in the tank body 1. The auxiliary connector assembly 3 forms a disassembly structure on the main connector assembly 2, enabling automatic sealing after disassembly. Furthermore, it automatically locks after sealing to prevent accidental opening and tank leakage. Based on the above, and according to the appendix... Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 12 and Figure 13As shown, the right end of the sub-tube seat 9 is snapped and fixedly connected to the seat cover by bolts. After the detent ring 12 is installed, it is movably sleeved on the outside of the right section of the sub-tube seat 9. And because a second spring 13 is installed at the connection between the detent ring 12 and the sub-tube seat 9, the second spring 13 is movably sleeved on the outside of the sub-tube seat 9. One end of the second spring 13 is inserted into the spring chamber of the seat cover in the sub-tube seat 9 and presses against the chamber wall. The other end of the second spring 13 is inserted into the spring chamber of the detent ring 12 and presses against the chamber wall. When the detent ring 12 is moved to slide on the outside of the right section of the sub-tube seat 9, the second spring 13 is compressed and undergoes elastic deformation. Subsequently, the second spring 13 returns to its original position by elastic deformation, which assists the detent ring 12 in automatically returning to its original position. Because the inner ring wall of the detonator 12 is recessed inward with an auxiliary groove 1201, and the left side wall of the auxiliary groove 1201 is inclined, and because the auxiliary groove 1201 provides a space for the pressure plate end of the locking member 14 to flip, after the locking member 14 is installed, the pressure plate end is movably inserted into the auxiliary groove 1201. After the detonator 12 slides, the inclined side wall of the auxiliary groove 1201 and the pressure plate end of the locking member 14 are pressed together, causing the locking member 14 to flip on the tube wall of the secondary tube seat 9, so that the torsion spring 15 is compressed and undergoes elastic deformation, and the hook end of the locking member 14 loses its engagement with the outer wall of the narrow part of the main tube seat 5, thus unlocking the locking of the secondary tube seat 9. The secondary tube seat 9 is then separated from the narrow part of the main tube seat 5 by pulling, thus completing the disassembly and separation operation between the secondary connector assembly 3 and the main connector assembly 2. Because the right end of the narrow section of the sealing component 6 is fixedly engaged with the first sealing ring 603, and the connection between the narrow and wide sections of the sealing component 6 is fixedly engaged with the second sealing ring 604, after the sub-connector assembly 3 and the main connector assembly 2 are disassembled and separated, the pusher 10 loses its pushing force on the sealing component 6. The sealing component 6 is reset by the compression elastic deformation and rotation elastic deformation of the first spring 8, and through the sliding fit between the first pin 601 and the "L"-shaped groove 403, the sealing component 6 is reset by sliding and rotating in sequence. The first sealing ring 603 is stuck inside the narrow section cavity of the wide section 4 of the main pipe seat, pressing against it. The second sealing ring 604 is inserted into the wide part of the main pipe seat 4, and presses against the connection between the narrow part of the main pipe seat 4 and the narrow part of the main pipe seat 5. The gap between the first sealing ring 603 and the second sealing ring 604 corresponds to the right end opening of the flow channel groove 401, completing the sealing treatment of the opening of the flow channel groove 401. The first pin part 601 is limited by the longitudinal groove in the "L" shaped groove 403, and the self-locking treatment after the sealing part 6 is reset is completed. This is the entire working process of the sealed joint for the storage tank. Any content not described in detail in this specification is prior art known to those skilled in the art.
