Description

Technical Field

[0001] This utility model belongs to the field of pressure vessel technology, specifically relating to a pressure vessel with adjustable pressure. Background Technology

[0002] A pressure vessel is a closed device that holds gas or liquid under pressure. It is generally composed of main components such as a cylinder, end caps, flanges, sealing elements, openings and pipes, and support base. Through changes in the pressure and temperature of the internal medium, it enables processes such as storage, transportation, reaction, and heat exchange of substances.

[0003] A search revealed Chinese patent application CN202420706034.1, which discloses a pressure-adjustable pressure vessel. The vessel includes a pressure tank body with a pressure relief pipe fixedly connected to its top. A sealing plug is slidably connected inside the pressure relief pipe, and a high-strength pressure-resistant spring is installed inside the pipe. In this prior art, the pressure inside the pressure tank body pushes the sealing plug to move within the pressure relief pipe. During this movement, the high-strength pressure-resistant spring contracts under pressure. When the sealing plug moves to the vent hole and connects with the inside of the pressure tank body, excess gas inside the pressure tank is discharged through the vent pipe. After the gas is discharged, the pressure inside the pressure tank body decreases, and the high-strength pressure-resistant spring returns to its elastic deformation, resetting the sealing plug for resealing. This achieves automatic adjustment of the internal pressure of the pressure vessel, effectively preventing damage caused by excessive pressure and improving safety and service life.

[0004] In the aforementioned prior art, a rotary valve is mainly used, which drives a threaded rod to move. The position of the lower sealing plug is adjusted by the cooperation between the threaded rod and the threaded plate. Then, the change in pressure inside the pressure vessel pushes the sealing plug to move, thereby controlling the pressure inside the pressure vessel. Although this control method is relatively convenient, the control index deviation is large due to the manual control method. Moreover, manually turning the valve requires the worker to use a lot of force due to the influence of factors such as the pressure inside the vessel and the elastic force of the spring. Therefore, the convenience of control is poor. Utility Model Content

[0023] Example

[0024] Please see Figure 1 - Figure 4As shown, a pressure vessel with adjustable pressure includes: a tank body 1, a connecting end 11 fixedly connected to the upper side of the tank body 1, and an air hole 12 opened inside one end of the connecting end 11; a feed inlet 13 fixedly connected to the end of the tank body 1 near the connecting end 11; and an adjustment component provided at the upper end of the connecting end 11. The adjustment component includes a cover plate 21 provided at the upper side of the connecting end 11, and a first sealing gasket 22 fixedly connected to the lower side of the cover plate 21, with the lower side of the first sealing gasket 22 fitting against the connecting end 11.

[0025] As can be seen from the above, during installation, the cover plate 21 drives the first sealing gasket 22 to fit with the connecting end 11, and the first sealing gasket 22 seals the fit between the cover plate 21 and the connecting end 11. At the same time, the cover plate 21 drives the sealing plate 215 and other components to be inserted into the connecting end 11 for installation.

[0026] Depend on Figure 4 It can be seen that the lower end of the cover plate 21 is fixedly connected to the connecting plate 23, and the internal thread of the connecting plate 23 is engaged with the fixing bolt 24, and the lower end thread of the fixing bolt 24 is engaged in the tank body 1.

[0027] As can be seen from the above, after the cover plate 21 drives the first sealing gasket 22 to fit with the connecting end 11, the fixing bolt 24 is screwed through and into the connecting plate 23 and the connecting end 11, thereby fixing the cover plate 21 and the like.

[0028] Specifically, regarding the above, please refer to... Figure 4 As shown, a motor 25 is fixedly connected to the inner side of the upper end of the cover plate 21, and a first gear 26 is fixedly connected to the output shaft of the motor 25. A second gear 27 is meshed at one end of the first gear 26, and the lower end of the second gear 27 is rotatably connected to the tank body 1.

[0029] As can be seen from the above, when it is necessary to adjust the height of the sealing plate 215, the motor 25 is started. After the motor 25 runs, the output shaft drives the first gear 26 to rotate. After the first gear 26 rotates, it drives the second gear 27 to rotate through gear meshing with the second gear 27.

[0030] Specifically, regarding the above, please refer to... Figure 3 and Figure 4 As shown, the lower end of the second gear 27 passes through the tank body 1 and is fixedly connected to the third gear 28, and the lower side of the third gear 28 is rotatably connected to the tank body 1. The outer end of the third gear 28 is meshed with the fourth gear 29, and the lower end of the fourth gear 29 is rotatably connected to the tank body 1.

[0031] As can be seen from the above, after the second gear 27 is turned, it synchronously drives the third gear 28 to rotate, and the third gear 28 drives the fourth gear 29 and the threaded cylinder 210 to rotate by meshing with multiple sets of fourth gears 29.

[0032] Specifically, regarding the above, please refer to... Figure 4 As shown, the lower middle end of the fourth gear 29 is fixedly connected to the threaded cylinder 210 through the tank body 1, and the threaded cylinder 210 has a threaded rod 211 engaged with the threaded rod 211 inside the lower end, and the lower end of the threaded rod 211 is fixedly connected to the bottom plate 212.

[0033] As can be seen from the above, after the threaded cylinder 210 rotates, it engages with the threaded rod 211, allowing the threaded rod 211 to be raised and lowered under the restriction of the base plate 212, thereby controlling the height of the base plate 212. After the base plate 212 is adjusted, it synchronously drives the second sealing washer 216 and the sealing plate 215 to move and adjust.

[0034] Specifically, regarding the above, please refer to... Figure 4 As shown, a sleeve 213 is fixedly connected to the lower middle of the cover plate 21, and a rod 214 is inserted into the lower end of the sleeve 213.

[0035] As can be seen from the above, when the height of the sealing plate 215 is adjusted, the insertion rod 214 moves under the restriction of the sleeve 213, and the movement of the sealing plate 215 is restricted by the sleeve 213 and the insertion rod 214.

[0036] Specifically, regarding the above, please refer to... Figure 4 As shown, a sealing plate 215 is fixedly connected to the lower end of the insertion rod 214, and a second sealing gasket 216 is fixedly connected to the lower side of the sealing plate 215. The lower side of the second sealing gasket 216 is in contact with the bottom plate 212, and a spring 217 is fixedly connected to the upper outer end of the second sealing gasket 216. The spring 217 is sleeved on the outside of the sleeve 213 and the insertion rod 214, and the upper end of the spring 217 is fixedly connected to the cover plate 21.

[0037] As can be seen from the above, when the internal pressure of the tank 1 increases, the air pressure pushes the sealing plate 215 upward. After the sealing plate 215 moves, it drives the second sealing gasket 216 to move. With the assistance of the sleeve 213 and the insert rod 214, the spring 217 is compressed. Then, when the height of the sealing plate 215 and the second sealing gasket 216 exceeds the air hole 12, the air pressure is discharged from the air hole 12 to relieve the pressure. After the pressure inside the tank 1 is released, the elastic potential energy of the spring 217 pushes the sealing plate 215 and the second sealing gasket 216 back to their original position to seal the upper end of the connection end 11.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
