Description

Technical Field

[0001] The present application relates to the technical field of pressure vessels, and in particular to a high-sealing pressure vessel. Background Art

[0002] A high-sealing pressure vessel is a container that can withstand internal pressure and has a very high sealing performance. It is designed to store or process various substances, such as gases and liquids, to prevent the internal medium from leaking into the surrounding environment, while also preventing external substances from entering the container.

[0003] Chinese patent publication number CN214171310U discloses a highly sealed pressure vessel that uses an intelligent control valve for emergency pressure relief and an annular heating plate to regulate the temperature inside the shell.

[0004] However, this pressure vessel needs to be used in various environments for a long time. In high-temperature environments, the metal parts of the valve may expand thermally, affecting the valve's sealing and movement accuracy. In corrosive environments, the valve components may corrode, reducing the valve's reliability and requiring frequent maintenance of the intelligent control valve, which can make it impossible to guarantee the sealing reliability of the pressure vessel. Utility Model Content

[0005] In order to improve the sealing reliability, the present application provides a high-sealing pressure container.

[0006] The application provides a high-sealing pressure vessel adopting the following technical solution:

[0007] A high-sealing pressure vessel comprises a tank body, a top cover for sealing the tank body is arranged above the tank body, a fastener for enhancing the sealing performance of the top cover is provided on the tank body, a pressure relief port is opened on the side wall of the tank body, and the pressure relief port is connected to a pressure relief box through a pressure relief assembly.

[0008] By adopting the above technical solution, the tank body is sealed and fasteners are used to strengthen the sealing effect and improve the sealing stability. In addition, the provision of pressure relief ports and pressure relief components prevents excessive pressure inside the tank body, thus preventing the tank body from being subjected to excessive pressure and causing structural damage such as rupture and deformation.

[0009] Optionally, a flange ring is provided on the top of the tank body, and a T-shaped slide is fixedly provided along the circumferential direction of the flange ring. The edge of the top cover is provided with a T-shaped slide opposite to the T-shaped slide. A card slot for connecting with the T-shaped slide is opened on the top cover, and the T-shaped slide is inserted into the card slot and slides with the T-shaped slide. An O-shaped rubber sleeve is provided between the flange ring and the top cover.

[0010] By adopting the above technical solution, when sealing, the card slot on the top cover is aligned with the T-shaped slide bar and inserted, and then the top cover is rotated along the direction of the T-shaped slide groove. At this time, the T-shaped slide groove restricts the movement of the top cover, thereby achieving reliable positioning and quick installation between the top cover and the tank body; at the same time, under the action of the O-shaped rubber sleeve, the gap between the top cover and the tank body is sealed, and the pressure inside the tank body forces the O-shaped rubber pad to deform and fit tightly against the gap between the top cover and the tank body, thereby enhancing the sealing between the top cover and the tank body.

[0011] Optionally, the pressure relief assembly includes a shell, a pressure relief rod, a spring and a baffle. The pressure relief rod is arranged in a horizontal direction and passes through the shell. The top of the pressure relief rod is fixedly connected to the shell. The spring is sleeved on the pressure relief rod. The top of the spring is fixedly connected to the shell. The baffle is fixedly set at the bottom of the spring. The pressure relief rod is slidably fitted with the baffle. The baffle is located on the side of the shell outlet close to the tank body.

[0012] By adopting the above technical solution, when the pressure in the tank is too high, the gas in the tube body produces an extrusion force on the baffle. When the extrusion force is greater than the elastic force of the spring, the gas will cause the spring to compress, pushing the baffle to move along the shell. When the baffle passes the shell outlet, the gas in the tank body flows into the pressure relief box along the shell outlet, thereby achieving pressure relief.

[0013] Optionally, a sealing ring is provided on the side wall of the baffle.

[0014] By adopting the above technical solution, the sealing ring seals the gap between the baffle and the shell, preventing the pressurized gas in the tank from flowing out on its own, thereby improving the sealing stability.

[0015] Optionally, the fastener includes a bracket and a movable plate, the bracket is a door-type frame, the bracket is hinged to the flange ring, the top of the bracket is arranged above the top cover, the movable plate is vertically mounted on the bracket and slidingly cooperates with the bracket, the movable plate is located below the flange ring, and the movable plate, flange ring and top cover are fixed together by bolts.

[0016] By adopting the above technical solution, after the top cover is sealed, the bracket is pulled and the top of the bracket is erected above the top cover. At the same time, the movable plate is moved along the direction of the bracket to the bottom of the flange ring, and then the movable plate, flange ring and top cover are fixed by bolts, thereby enhancing the sealing stability of the container.

[0017] Optionally, a groove is provided on the flange ring, the top cover is provided with a same groove relative to the flange ring, and the bracket is provided on the top cover.

[0018] By adopting the above technical solution, the bracket is fixed in the groove. On the one hand, the fixing effect of the bracket prevents the top cover from rotating, thereby improving the sealing stability; on the other hand, the design of the groove can inform the operator whether the top cover is installed in place. When the grooves on the top cover and the flange ring are aligned with each other, the top cover is rotated into place and the sealing effect can be achieved.

[0019] Optionally, a pressure gauge is provided on the top cover.

[0020] By adopting the above technical solution, the pressure gauge installed on the top cover can monitor the pressure changes inside the tank in real time, making it convenient for operators to understand the working status inside the container in a timely manner and ensure safe operation.

[0021] Optionally, the sealing ring is made of nitrile rubber.

[0022] By adopting the above technical solution, the sealing ring is made of nitrile rubber, which enhances the sealing between the baffle and the shell outlet, further improves the reliability of the pressure relief assembly, and ensures the safety performance of the pressure vessel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging the flange ring, top cover, T-shaped slide, T-shaped slide, card slot and O-shaped rubber pad, when installing the top cover, align the card slot on the top cover with the T-shaped slide and insert it, then rotate the top cover along the direction of the T-shaped slide. At this time, the T-shaped slide restricts the movement of the top cover, achieving reliable positioning between the top cover and the tank body and quick installation. At the same time, the gap between the top cover and the tank body is sealed by the action of the O-shaped rubber sleeve. The pressure inside the tank forces the O-shaped rubber pad to deform and fit tightly against the gap between the top cover and the tank body, thereby enhancing the sealing between the top cover and the tank body.

[0025] 2. By setting up the bracket, movable plate and fixed plate, after the top cover is sealed, pull the bracket to set the fixed plate above the top cover, and at the same time move the movable plate along the direction of the bracket to the bottom of the flange ring, and then fix the movable plate, flange ring, top cover and fixed plate with bolts to enhance the sealing stability of the container.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a high-sealing pressure container. Figure 1 A highly sealed pressure vessel comprises a tank body 1 with a pressure relief vent 2 formed on the side wall thereof. When the internal pressure of the tank body 1 is too high, the pressure can be released through the pressure relief vent 2. The pressure relief vent 2 is connected to a pressure relief box 3 through a pressure relief assembly. The pressure relief box 3 is provided on one side of the tank body 1.

[0034] refer to Figure 1 and Figure 2 The pressure relief assembly includes a housing 4, a pressure relief rod 5, a spring 6, and a baffle 7. The housing 4 is connected to the pressure relief port 2 in the horizontal direction. The pressure relief rod 5 is inserted into the housing 4 and is arranged parallel to the housing 4. The end of the pressure relief rod 5 is fixedly connected to the end of the housing 4. The spring 6 is sleeved on the pressure relief rod 5, and one end of the spring 6 is fixedly connected to the housing 4. The other end of the spring 6 is fixedly connected to the baffle 7. The end of the pressure relief rod 5 is slidably matched with the baffle 7. In order to seal the housing 4, the baffle 7 is located at the outlet of the housing 4 and close to the side of the tank body 1. At the same time, a sealing ring 8 is provided on the edge of the baffle 7 that contacts the housing 4. The material of the sealing ring 8 is nitrile rubber.

[0035] Reference Figure 1 、 Figure 3 and Figure 4The tank body 1 is cylindrical, with a flange ring 9 fixedly installed at the top opening of the tank body 1. The flange ring 9 is provided with four grooves 10, which are arranged in pairs opposite to each other. A top cover 11 is detachably provided on the flange ring 9. The top cover 11 is used to seal the tank body 1. The top cover 11 is provided with four grooves 10 arranged opposite to the flange ring 9. Two T-shaped slides 12 are fixedly installed along the circumferential direction on the upper edge of the flange ring 9. The two T-shaped slides 12 are arranged opposite to each other. The side of the top cover 11 that contacts the flange ring 9 is provided with two T-shaped grooves 13 arranged opposite to the two T-shaped slides 12. The top cover 11 is provided with a slot 14 for connecting with the two T-shaped slides 12. The T-shaped slides 12 are inserted into the slot 14 and slide in conjunction with the T-shaped grooves 13. In order to ensure the sealing of the tank body 1. An O-shaped rubber sleeve 15 is provided between the gap between the flange ring 9 and the top cover 11.

[0036] Reference Figure 1 、 Figure 3 and Figure 5 The tank body 1 is provided with fasteners for strengthening the sealing performance of the top cover 11. The fasteners include a bracket 16 and a movable plate 17. The bracket 16 is hinged on both sides of the flange ring 9. The bracket 16 is a door-type frame. The top of the bracket 16 covers the top of the top cover 11. The movable plate 17 is vertically mounted on the bracket 16 and slides with the bracket 16. The movable plate 17 is located below the flange ring 9 and contacts the flange ring 9. The movable plate 17, the flange ring 9 and the top cover 11 are fixed together by bolts. Both sides of the bracket 16 are embedded in the groove 10, and the bracket 16 is mounted on the top cover 11. A pressure gauge 18 is provided on the top cover 11. The added pressure gauge 18 can not only monitor the pressure status in the container in real time and detect abnormal conditions in time, but also provide more accurate data to support decision-making.

[0037] The implementation principle of the highly sealed pressure vessel of the present embodiment is as follows: through the special structural design between the tank body 1 and the top cover 11, the cooperation of the T-shaped slide 12 and the T-shaped groove 13, and the sealing effect of the O-shaped rubber sleeve 15, a tight seal is achieved between the top cover 11 and the tank body 1. The pressure within the tank body 1 forces the O-shaped rubber sleeve to deform and fit tightly against the gap between the top cover 11 and the tank body 1, further enhancing the sealing between the top cover 11 and the tank body 1.

[0038] The fastener design also simplifies the installation and removal of the top cover 11, enhancing the sealing performance of the entire system. After the top cover 11 is sealed, the bracket 16 is moved and the top of the bracket 16 is placed above the top cover 11. At the same time, the movable plate 17 is moved along the bracket 16 to below the flange ring 9. The movable plate 17, flange ring 9, and top cover 11 are then fixed with bolts, thereby enhancing the sealing stability of the container.

[0039] The design of the pressure relief assembly ensures that the overpressure in the container is effectively released. When the pressure in the tank body 1 is too high, the gas in the tube body produces an extrusion force on the baffle 7. When the extrusion force is greater than the elastic force of the spring 6, the gas will cause the spring 6 to compress, pushing the baffle 7 to move along the shell 4. When the baffle 7 passes over the outlet of the shell 4, the gas in the tank body 1 flows into the pressure relief box 3 along the outlet of the shell 4, thereby achieving pressure relief and improving safety performance.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
