Description

Technical Field

[0001] The utility model relates to the field of float valves, in particular to a gear type high-precision float valve. Background Technique

[0002] A float valve is a device for automatically controlling the liquid level. It controls the opening and closing state of the valve by the up and down movement of the float ball with the change of the liquid level, so as to maintain the liquid within a set range and prevent overflow or dryness. When the existing mechanical float valve is in use, the relative precision of controlling the opening and closing of the valve is relatively low, which may lead to the inability to effectively and accurately control the amount of liquid. Although the electric float valve has higher precision, its relative cost is relatively expensive. Therefore, applying the electric float valve to some electronic devices may greatly increase the manufacturing cost of the electronic devices, resulting in a relatively low cost performance of the electronic devices. For this reason, a gear type high-precision float valve is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a gear type high-precision float valve is proposed. Through the cooperation of the bearing and the rotating shaft, the friction and wear of the float valve are reduced, and the operation stability and service life are improved.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A gear type high-precision float valve, including a valve seat frame. The edge of the lower surface of the valve seat frame is fixedly connected with a square valve seat. A flow groove is opened at the center of the upper surface of the valve seat frame. Both sides inside the valve seat frame are fixedly connected with bearings. The inner walls of the bearings are fixedly connected with first rotating shafts. A valve plate is fixedly connected to the middle of the shaft body of the first rotating shaft. One end of the first rotating shaft penetrates through the valve seat frame and is fixedly connected with a driven gear. A second rotating shaft is arranged inside the square valve seat. One end of the second rotating shaft penetrates through the square valve seat and is fixedly connected with a driving gear. A connecting rod is fixedly connected to the shaft body of the second rotating shaft. A float ball is fixedly connected to the lower surface of the connecting rod;

[0006] Through the above technical solution, the movement of the float ball can accurately control the gear transmission, so as to realize the accurate adjustment of the fluid flow rate.

[0007] Further, the end of the second rotating shaft far from the driving gear is rotatably connected with the inner wall of the square valve seat;

[0008] Through the above technical solution, the end of the second rotating shaft far from the driving gear is rotatably connected with the inner wall of the square valve seat, so as to better improve the rotation stability while the second rotating shaft is rotating.

[0009] Further, the floating ball is made of plastic;

[0010] Through the above technical solution, since the floating ball is made of plastic, the floating ball is light in weight and has better corrosion resistance, and is more suitable for liquids with strong corrosiveness.

[0011] Further, the driving gear meshes with the driven gear;

[0012] Through the above technical solution, by the driving gear meshing with the driven gear, the opening and closing of the valve plate can be controlled more precisely.

[0013] Further, the upper surface of the valve plate is closely attached to the inner wall of the flow channel;

[0014] Through the above technical solution, by the upper surface of the valve plate being closely attached to the inner wall of the flow channel, the throttling of the liquid can be effectively controlled.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1-5 , an embodiment provided by the present invention:

[0026] A gear-type high-precision floating ball valve includes a valve seat frame 1. A square valve seat 3 is fixedly connected to the edge of the lower surface of the valve seat frame 1. A flow-through groove 2 is provided at the center of the upper surface of the valve seat frame 1. Bearings 9 are fixedly connected to both sides inside the valve seat frame 1. The inner walls of the bearings 9 are fixedly connected with first rotating shafts 10. The middle of the shaft body of the first rotating shaft 10 is fixedly connected with a valve plate 4. One end of the first rotating shaft 10 penetrates through the valve seat frame 1 and is fixedly connected with a driven gear 5. A second rotating shaft 11 is arranged inside the square valve seat 3. One end of the second rotating shaft 11 penetrates through the square valve seat 3 and is fixedly connected with a driving gear 6. A connecting rod 7 is fixedly connected to the shaft body of the second rotating shaft 11. A floating ball 8 is fixedly connected to the lower surface of the connecting rod 7;

[0027] The movement of the floating ball can precisely control the gear transmission, thereby realizing the precise adjustment of the fluid flow rate.

[0028] The end of the second rotating shaft 11 away from the driving gear 6 is rotatably connected to the inner wall of the square valve seat 3. By rotatably connecting the end of the second rotating shaft 11 away from the driving gear 6 to the inner wall of the square valve seat 3, the rotational stability of the second rotating shaft 11 can be better improved while it rotates. The floating ball 8 is made of plastic. By making the floating ball 8 of plastic, the floating ball 8 has a light weight and better corrosion resistance, and is more suitable for liquids with strong corrosiveness. The driving gear 6 and the driven gear 5 are meshed with each other. By meshing the driving gear 6 and the driven gear 5 with each other, the opening and closing of the valve plate 4 can be controlled more precisely. The upper surface of the valve plate 4 is closely attached to the inner wall of the flow-through groove 2. By closely attaching the upper surface of the valve plate 4 to the inner wall of the flow-through groove 2, the liquid throttling can be effectively controlled.

[0029] Working principle: When in use, install this float valve in the specified area. When the liquid level rises, it drives the float 8 to rise. Then, when the float 8 rises, it drives the connecting rod 7 to move, so that the connecting rod 7 drives the second rotating shaft 11 to rotate. Thus, the second rotating shaft 11 drives the driving gear 6 to rotate. Then, through the meshing of the driving gear 6 and the driven gear 5, the first rotating shaft 10 rotates. Thus, the first rotating shaft 10 rotates inside the valve seat frame 1 through the bearing 9, so that the rotation of the first rotating shaft 10 drives the valve plate 4 to move, so that the valve plate 4 seals the flow channel 2.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
