Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing ring technology, and in particular to a corrosion-resistant sealing ring structure for hydrogen-oxygen generators. Background Technology
[0002] Hydrogen-oxygen generators are devices that decompose water molecules into hydrogen and oxygen based on the principle of water electrolysis. They are widely used in the energy, medical, and industrial processing fields. Their core working component is an electrolytic cell, which contains electrode plates and electrolyte. Under the action of direct current, water molecules decompose at the anode to produce oxygen and at the cathode to produce hydrogen. Since hydrogen is flammable and explosive, and oxygen supports combustion, leakage not only wastes energy but may also cause serious safety accidents. Moreover, the electrolyte is mostly a strongly alkaline solution, so the requirements for sealing are very strict.
[0003] However, hydrogen-oxygen generators mostly use ordinary rubber sealing rings and metal gaskets for sealing, which cannot maintain sufficient sealing pressure and are prone to gaps when pressure fluctuates, leading to gas leakage. Moreover, the sealing rings need to be replaced and maintained after long-term operation, but traditional equipment is cumbersome and time-consuming to disassemble. The nitrile rubber material nitrile rubber swells and ages rapidly in strongly alkaline electrolytes, resulting in a short service life. Ordinary metal gaskets are easily corroded by alkaline solutions, producing metal ions that contaminate the electrolyte and reduce electrolysis efficiency. However, the current market uses a composite design of nitrile rubber body and fluororubber sealing lip. Nitrile rubber provides elasticity and cost advantages, while the fluororubber sealing lip directly contacts the electrolyte, achieving a balance between corrosion resistance and economy. However, during operation, pressure fluctuations can cause it to slip and create gaps, wasting costs. At the same time, the disassembly process is too cumbersome and time-consuming for maintenance and inspection. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a corrosion-resistant sealing ring structure for hydrogen-oxygen generators, aiming to improve the problems in the prior art where pressure fluctuations cause slippage and gaps, and the disassembly process is too cumbersome and time-consuming.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a corrosion-resistant sealing ring structure for a hydrogen-oxygen generator, comprising a lower outer shell, an upper outer shell slidably connected to the top of the outer wall of the lower outer shell, friction rings fixedly connected to the inner walls of both the lower and upper outer shells, buffer springs fixedly connected between adjacent friction rings, fastening rings fixedly connected to the inner walls of each friction ring, connecting plates fixedly connected to the front and rear sides of the outer walls of the fastening rings, threaded rods threadedly connected to the outer walls of multiple connecting plates, nuts threadedly connected to the outer walls of multiple threaded rods, a fixing groove formed on the outer wall of the friction ring, a sealing ring fixedly connected to the inner wall of the fastening ring, and a fixing mechanism fixedly connected to the top of the outer wall of the lower outer shell, the fixing mechanism being used to protect and fix the friction rings.
[0006] As a further description of the above technical solution:
[0007] The fixing mechanism includes screws, the outer walls of which are threaded to the lower outer shell. A fixing post is fixedly connected to the top of each screw, and a rubber ball is fixedly connected to the top of each fixing post. A rubber sleeve is fixedly connected to the bottom of the outer wall of the upper outer shell. Grooves are formed on the inner walls of both the lower and upper outer shells. Connecting posts are slidably connected to the inner walls of multiple grooves. A helical spring is fixedly connected inside the multiple connecting posts, and a ball bearing is fixedly connected to the top of each connecting post.
[0008] As a further description of the above technical solution:
[0009] Both the lower and upper outer shells have circular holes on their outer walls, and the left and right sides of the outer wall of the lower outer shell are fixedly connected to fixing plates.
[0010] As a further description of the above technical solution:
[0011] Both of the fixed plates have threaded rods 2 threaded to their top outer walls, and the outer walls of the multiple threaded rods 2 are each threaded with nuts 2.
[0012] As a further description of the above technical solution:
[0013] Each of the threaded rods has a handle fixedly connected to its top end, and a buffer pad is fixedly connected to the bottom of the lower housing.
[0014] As a further description of the above technical solution:
[0015] Each of the buffer pads has a return spring fixedly connected to its bottom, and each of the return springs has a rubber pad fixedly connected to its end.

[0018] As a further description of the above technical solution:
[0019] The top of the upper outer shell is threaded with screws, and the inner walls of both lower outer shells and the upper outer shell are fixedly connected with protective rings.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the friction ring is first initially tightened by using a fastening ring. The threaded rod on the fastening ring is used to rotate the nut to tighten the fastening ring and prevent it from deforming during sealing. Then, the friction ring is connected to the sealing ring. The buffer spring between the two friction rings reduces the friction generated during operation and also provides buffering. Then, the lower outer shell and the upper outer shell are connected to the friction ring to form protection, making the sealing process smooth.
[0022] 2. In this utility model, firstly, the screw at the top of the lower outer shell is used to make the rubber ball at its top snap into the rubber sleeve at the bottom of the upper outer shell. Due to the material of the rubber ball, it can be squeezed and deformed to fix it in the rubber sleeve. Then, when the device is placed between the lower outer shell and the upper outer shell, the pushing force is used to make the balls on the lower outer shell and the upper outer shell retract into the groove, and then fix the friction ring.

[0036] Specifically, both the lower outer shell 1 and the upper outer shell 3 have round holes 12 on their outer walls. The left and right sides of the outer wall of the lower outer shell 1 are fixed with fixing plates 13 for support. The top of the fixing plate 13 is connected to a threaded rod 14 by a thread, and the outer wall is fitted with a nut 16 for easy adjustment and fixing. The top is connected to a handle 15 to improve convenience. The bottom of the lower outer shell 1 is fixed with a buffer pad 17 to effectively reduce the impact force.
[0037] Please see the appendix Figure 1 - Appendix Figure 3 The bottom of each of these buffer pads 17 is securely connected to a return spring 18 to ensure that it can quickly return to its original position after being subjected to external force. The ends of multiple return springs 18 are reliably connected to rubber pads 19 to provide additional cushioning and shock absorption. The top inner wall of the upper outer shell 3 is securely connected to a sound-absorbing ring 20, which can effectively absorb internal noise and reduce sound transmission. The top outer wall of the upper outer shell 3 is also securely connected to a ring cover 21, which protects the internal structure and prevents external impurities from entering. To ensure the stability of the upper outer shell 3, its top is also secured with screws 22 by threaded connection, which is convenient for disassembly and ensures tightness of connection. The inner walls of the two lower outer shells 1 and the upper outer shell 3 are all reliably connected to protective rings 23.
[0038] Specifically, the bottom of the buffer pad 17 is firmly connected to the return spring 18, which can quickly return to its original position. The end of the return spring 18 is connected to the rubber pad 19 to provide cushioning and shock absorption. The inner wall of the top of the upper housing 3 is fixed with a sound-absorbing ring 20 to absorb internal noise. The outer wall of the top is connected with a ring cover 21 to protect the internal structure and prevent impurities from entering. The top is also fixed with a threaded screw 22 to ensure stability and easy disassembly. Then, the inner walls of the lower housing 1 and the upper housing 3 are connected with a protective ring 23.
[0039] Working principle: First, the fastening ring 7 surrounds the sealing ring 8. Then, after alignment, the connecting plate 9 on the sealing ring 8 is rotated, and the nut 11 is rotated to rotate the threaded rod 10, thereby fastening the fastening ring 7 to the sealing ring 8 and preventing the sealing effect from being reduced. Then, friction rings 4 are fitted on the top and bottom of the sealing ring 8. The buffer spring 5 between the two friction rings 4 prevents the sealing ring 8 from falling off when subjected to force. Then, the top and bottom of the friction rings 4 are connected by the lower outer shell 1 and the upper outer shell 3 to form the final protection. When an external force is encountered, the force is applied to the lower outer shell 1 and the upper outer shell 3 and then transmitted to the friction rings 4. The friction rings 4 absorb the force using the buffer spring 5, achieving stable and highly sealing operation and preventing them from falling off due to external force, which would reduce the sealing effect.
[0040] Since multiple screws 201 are connected to the outer wall of the lower outer shell 1, the rubber ball 203 at the top of the screw 201 is connected to the rubber sleeve 204 at the bottom of the outer wall of the upper outer shell 3. Due to its material, the rubber ball 203 can be compressed and reduced in size, thus being stuck in the rubber sleeve 204. When the sealing structure is placed into the lower outer shell 1 and the upper outer shell 3, the force generated during placement causes the ball bearings 208 on the inner walls of the lower outer shell 1 and the upper outer shell 3 to be pressed downwards, causing the helical spring 207 to be compressed and driving the connecting post 206 to retract into the groove 205. When the entire device is placed in, the ball bearings 208 on the inner walls of the lower outer shell 1 and the upper outer shell 3 are used to hold the top and bottom of the outer wall of the friction ring 4, deepening the fixation. When replacement is required, the lower outer shell 1 and the upper outer shell 3 can be separated and removed. At the same time, the ball bearings 208 have no force and are reset with the help of the helical spring 207, achieving quick fixation and quick disassembly, which is convenient for maintenance and replacement.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
