[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a pressure regulating device for filling hydrogen chloride, including a device body 1. A sliding plate 2 and an adjusting plate 5 are slidably arranged inside the device body 1. A turntable 3 is rotatably connected to the opposite side of the sliding plate 2 and the adjusting plate 5. The device body 1 is provided with a rotating assembly 4 for simultaneously adjusting the rotation of the two turntables 3, and a sliding assembly 6 for adjusting the sliding of the adjusting plate 5. The turntable 3 has mounting openings 7 arranged in a circumferential array. Mounting plates 8 are adapted to the mounting openings 7. A spring 9 is arranged between the upper and lower mounting plates 8 of the same group. The adjusting plate 5 has a through opening 10 located on the circumferential trajectory of the mounting opening 7. The sliding plate 2 is located above the adjusting plate 5. A box opening is opened on one side of the device body 1, and a box door is rotatably connected to the device body 1 at the box opening. The box door is adapted to the box opening.

[0026] like Figure 5 and Figure 6 As shown, the rotating assembly 4 includes a fixed tube 401 fixedly connected to the bottom of the top turntable 3. A fixed rod 402 is slidably disposed in a fixed groove opened at the bottom end of the fixed tube 401. The bottom end of the fixed rod 402 rotates on the top wall inside the device body 1. The bottom turntable 3 is slidably sleeved on the outside of the fixed tube 401. A first groove with a circumferential array is opened on the outside of the fixed tube 401. A first wire block is slidably disposed in the cavity of the first groove. The first wire block is fixedly disposed on the inner wall of the bottom turntable 3. A second groove with a circumferential array is opened on the outside of the fixed rod 402. A second wire block is slidably disposed in the cavity of the second groove. The second wire block is fixed on the inner wall of the fixed tube 401.

[0027] like Figure 3 and Figure 6 As shown, a mounting bracket 11 is installed on the inner wall of the device body 1. The sliding component 6 includes a first toothed ring 601 that rotates on the mounting bracket 11 and second toothed rings 602 distributed in a circumferential array. Each second toothed ring 602 is engaged with the first toothed ring 601. A threaded tube is fixedly provided inside the second toothed ring 602. A first screw 603 is threaded inside the threaded tube. The first screw 603 is fixed to the bottom of the adjusting plate 5.

[0028] like Figure 6 As shown, a second screw 12 and a stabilizing rod 13 are rotatably mounted at the bottom of the adjusting plate 5 and at the opening 10. A lifting plate 14 is adapted inside the opening 10. The lifting plate 14 has threaded holes and stabilizing holes respectively at the corresponding positions of the second screw 12 and the stabilizing rod 13. The lifting plate 14 is threadedly sleeved on the outside of the second screw 12 through the threaded hole, and the lifting plate 14 is slidably sleeved on the outside of the stabilizing rod 13 through the stabilizing hole.

[0029] like Figure 1 - Figure 6 As shown, worm gears 15 are fixedly sleeved on the outer side of the fixed rod 402, the outer side of the threaded pipe, and the outer side of the second screw 12. A worm 16 is meshed with one side of the worm gear 15. Two sleeve blocks are rotatably sleeved on the outer side of the three worms 16. Each sleeve block is fixedly set on the bottom wall inside the device body 1 and the upper part of the mounting bracket 11.

[0030] like Figure 1 - Figure 6 As shown, three rocking disks 17 are rotatably arranged on the outer side of the device body 1, and one side of each rocking disk 17 is fixedly connected to one end of each worm gear 16.

[0031] When the gas pressure needs to be adjusted, the rocker plate 17 on the sliding assembly 6 is rotated. The rocker plate 17 then uses the worm gear 15 and worm 16 on the mounting bracket 11 to rotate one of the second gear rings 602. The second gear ring 602 then uses the first gear ring 601 to drive the other second gear rings 602 to rotate in the same direction. In this way, the first screw 603 drives the adjusting plate 5 to rise and fall, thereby adjusting the elastic force of the spring 9 and achieving the purpose of regulating the gas pressure.

[0032] When it is necessary to disassemble the spring 9, rotate the rocker plate 17 on the rotating assembly 4. The rocker plate 17 will drive the fixed tube 401 to rotate through the fixed rod 402. The fixed tube 401 will drive the two turntables 3 to rotate together, so that the mounting port 7 of the spring 9 to be disassembled on the turntable 3 is directly above the through port 10. At this time, the spring 9 and the mounting plate 8 can be taken out through the through port 10. Otherwise, the spring 9 and the mounting plate 8 can be installed through the through port 10.

[0033] Since the spring 9 may be in a compressed state during disassembly and assembly, in order to avoid the elastic force generated by the spring 9's reset from affecting the disassembly and assembly of the spring 9, the worm gear 15 and worm 16 on the second screw 12 can be rotated in advance, and the second screw 12 can be rotated. The second screw 12 will drive the lifting plate 14 to rise and fall, and the lifting plate 14 will be inserted into the through port 10. When taking out the spring 9, you only need to slowly lower the lifting plate 14, and vice versa.

[0034] like Figure 1 and Figure 2 As shown, a pressure relief pipe 18 is fixedly connected to the top of the device body 1, and an air inlet pipe and an air outlet pipe are fixedly connected to both sides of the device body 1 respectively. A support rod 19 is fixedly installed on the top of the sliding plate 2, and a baffle 20 is fixedly installed at the top of the support rod 19. A sealing gasket for sealing the opening of the pressure relief pipe 18 is installed on the upper part of the baffle 20.

[0035] In use, gas enters through the inlet pipe. When the gas pressure is higher than the set pressure, the gas pressure pushes the sliding plate 2 to slide downward. The sliding plate 2 drives the support rod 19 to move downward. The support rod 19 drives the baffle 20 to move downward, discharging the gas from the pressure relief pipe 18. When the gas pressure is normal, under the action of the spring 9, the baffle 20 squeezes the sealing gasket to block the pipe hole of the pressure relief pipe 18.

[0036] like Figure 2 and Figure 4 As shown, a thin rod 21 and a thick tube 22 are fixedly installed on opposite sides of two mounting plates 8 in the same group. The thick tube 22 is slidably sleeved on the outside of the thin rod 21, and the spring 9 is sleeved on the outside of the thick tube 22.

[0037] By utilizing the telescopic cooperation between the thin rod 21 and the thick tube 22, the stability of the spring 9 under compression can be improved.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
