Ball float valve structure used for gas-liquid separation device in ozone field

Abstract

The invention discloses a ball float valve structure used for a gas-liquid separation device in the ozone field. The ball float valve structure is characterized by comprising a bracket (4), a sealing head (1) is arranged on the bracket (4), an exhaust passage (1-3) and an air hole (1-4) are arranged in the sealing head (1), a guide post (1-1) is arranged at the lower end of the sealing head (1), a boss (1-2) is arranged at the lower end of the guide post (1-1), a sealing guide rod (3) is arranged in the bracket (4), an inner hole (3-1) is arranged at the upper end the sealing guide rod (3), an elastic sealing pad (2) is arranged in the inner hole (3-1), an outer diameter step (3-2) is arranged on the sealing guide rod (3), a spring (5) is sleeved below the outer diameter step (3-2) on thesealing guide rod (3), the lower end of the bracket (4) is connected with one end of a float connecting rod (7), and the other end of the float connecting rod (7) is connected with a float (9) through a float rotating shaft (8). The invention has simple and practical structure, favorable sealing effect, stability and reliability.

Description

Technical field: [0001] The invention relates to a float valve structure used in a gas-liquid separation device in the ozone field, and belongs to the technical field of ozone generation. Background technique: [0002] As a highly effective antibacterial agent, ozone has been used more and more widely in various fields. At present, the most important application method is to dissolve ozone in water, and use ozone water for sterilization and disinfection. However, due to the low solubility of ozone gas in water, part of the ozone gas is not dissolved in the water during the mixing process, and if the remaining ozone gas flows out together with the ozone water, it will affect the health of the user. Therefore, a gas-liquid separator that separates the remaining ozone gas from water is necessary. [0003] At present, the key components of the float valve in the gas-liquid separation device in the ozone field basically follow the float valve in the tap water field or adopt a simple f...

AI Technical Summary

Problems solved by technology

[0005] 1. There is no positioning structure between the thimble and the vent hole in this structure, so when the position of the buoy is shifted, it is easy to dislocate and the vent hole cannot be completely closed, resulting in the flow of ozone water from the vent hole

[0006] 2. There is no positioning structure between the thimble and the vent hole, but it still needs to achieve the function of complete sealing, that is, the processing accuracy of each part is very high. Whether it is a machined part or a molded part, it is very difficult, which means that the cost will increase. Substantial increase, difficult to control quality

[0007] 3. The float valves currently used are made of conventional plastic materials, which have poor ozone resistance. Therefore, after a long period of use, due to the strong oxidation ability of ozone on conventional plastic materials, they are prone to damage and lose their functions.

[0008] 4. The float valves currently used all use conventional rubber materials to seal the vent holes, and their ozone resistance is poor. Therefore, after a long period of use, due to the strong oxidation ability of ozone on conventional rubber materials, they are prone to damage and seal failure

[0009] To sum up, the existing floating ball valve structure applied in the field of ozone is prone to the problem of seal failure and leakage of ozone water from the vent hole, which in turn makes the gas-liquid separation function invalid.
