Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oil unloading anti-overflow valves, and in particular relates to a gasoline recovery device with an oil unloading anti-overflow valve. Background Art
[0002] When the tanker truck unloads oil into the underground tank at the gas station, the liquid level of the tank cannot be directly observed during unloading because the tank is below the ground. In order to prevent oil from overflowing when the ground tank is filled, the staff began to manufacture a valve that can automatically cut off the oil inlet passage (oil unloading anti-overflow valve). This valve mainly controls the opening and closing of the valve plate to control the on-off of the oil inlet. When the oil in the ground tank rises to the standard liquid level, the valve plate blocks the oil inlet passage, and the oil will not continue to be added to the tank, and the unloading work is completed. After that, as the ground tank refuels cars for a period of time, the oil drops below the standard liquid level, and the valve plate will automatically open. When the tanker truck needs to unload oil again, the oil inlet passage is not blocked, and the oil can be smoothly added to the underground tank.
[0003] In the existing gasoline recovery device of the oil unloading anti-overflow valve, the oil unloading anti-overflow valve for gasoline recovery mainly drives the valve plate to open and close through a float and a connecting rod mechanism. Since the float is installed on the outside of the valve body and the valve plate is installed on the inside of the valve body, it is necessary to drill a hole in the valve body wall to achieve the connection of its connecting rod mechanism. In order to prevent gasoline leakage, a mechanical seal is required, such as a sealing ring. If only a sealing ring is used to achieve sealing, the sealing ring is prone to aging over a long period of time, resulting in gasoline leakage.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0028] See also Figure 1-Figure 6As shown, the utility model is a gasoline recovery device with an oil unloading anti-overflow valve, comprising a valve body 1, a flange 2 is fixedly installed on the top of the valve body 1, a float 3 is slidably installed inside the valve body 1, the float 3 is slidably installed in the inner cavity of the valve body 1, a driving component 4 is fixedly installed on the top of the float 3, a sealing component 5 is arranged in the inner cavity of the driving component 4, and the sealing component 5 is fixedly installed in the inner cavity of the valve body 1.
[0029] The valve body 1 is vertically installed in the underground oil well. The tank truck is connected to the flange 2 fixedly installed on the valve body 1 through the oil unloading pipe to inject oil into the underground oil well. When the liquid level of the underground oil well rises to the height of the float 3, the float 3 moves upward due to the buoyancy. When the float 3 rises to one end of the valve body 1, the float 3 will fit with the valve body 1, thereby closing the oil unloading channel of the valve body 1. At the same time, during the rising process of the float 3, the float 3 will push the driving component 4 to move under the support of the valve body 1, and then the driving component 4 will contact the sealing component 5 and push the sealing component 5 to move. The sealing component 5 is a cavity on the central axis to the sealing component 5. The components inside the component 5 are evenly converged on the central axis of the sealing component 5, and the sealing component 5 is in a sealed state, and the oil unloading channel of the valve body 1 is closed again. When the oil unloading channel of the valve body 1 is closed, the oil unloading pipeline will shake violently due to the impact. The staff knows that the oil is full and closes the valve of the tanker truck. When the underground oil well refuels the vehicle, the oil level gradually decreases, and the float 3 moves downward under the elastic action of the driving component 4 itself. Then the sealing component 5 will return to its initial position under its own elastic action. At this time, the sealing component 5 forms a cavity on the central axis to facilitate the next injection of oil.
[0030] As a result, the float 3 moves upward due to the buoyancy, so that the float 3 fits against the valve body 1, and the drive assembly 4 contacts the sealing assembly 5. The sealing assembly 5 is a cavity on the central axis, and the components inside the sealing assembly 5 are evenly converged on the central axis of the sealing assembly 5, thereby closing the oil unloading channel of the valve body 1, thereby preventing gasoline leakage and avoiding the phenomenon of gasoline leakage caused by only using a sealing ring for sealing, which is prone to aging over a long period of time.
[0031] In one embodiment, for the valve body 1 , the valve body 1 includes a shell 101 , and a support frame 102 is fixedly installed inside the shell 101 .
[0032] The support frame 102 is used to support the float 3 .
[0033] In one embodiment, for the above-mentioned float 3, the float 3 includes a sliding rod 301, the sliding rod 301 is slidably installed on the support frame 102, a valve plate 302 is fixedly installed at the bottom of the sliding rod 301, and a sealing ring 303 is sleeved on the circumferential surface of the valve plate 302.
[0034] When the liquid level in the underground oil well rises to the height of the valve plate 302, the valve plate 302 moves upward due to the buoyancy, and then the valve plate 302 drives the sealing ring 303 on the circumferential surface to rise until the valve plate 302 contacts the outer shell 101. At this time, the sealing ring 303 will be embedded in the outer shell 101 to close the oil unloading channel of the valve body 1.
[0035] In one embodiment, for the above-mentioned driving component 4, the driving component 4 includes a sliding plate 401, the sliding plate 401 is fixedly installed on the sliding rod 301, the sliding plate 401 is slidably installed with the housing 101, and a plurality of first triangular blocks 402 are fixedly installed on the top of the sliding plate 401.
[0036] A moving rod 403 is fixedly installed on the top of the sliding plate 401, one end of the moving rod 403 is slidably installed on the support plate 404, and the support plate 404 is fixedly installed in the inner cavity of the shell 101. A spring 405 is sleeved on the circumferential surface of the moving rod 403, one end of the spring 405 stops on the sliding plate 401 and the other end stops on the support plate 404.
[0037] The sealing assembly 5 includes a driving disk 501, and a plurality of second triangular blocks 502 are fixedly installed below the driving disk 501. The bottoms of the plurality of second triangular blocks 502 are slidably matched with the tops of the plurality of first triangular blocks 402. A plurality of rotating rods 503 are slidably installed in the inner cavity of the driving disk 501, and a shielding plate 504 is fixedly installed at one end of the plurality of rotating rods 503. The support plate 404 is provided with a sliding groove 406 slidably installed with the plurality of rotating rods 503.
[0038] A tension spring 505 is fixedly mounted on the circumferential surface of the driving disk 501 , and the other end of the tension spring 505 is fixedly mounted on the supporting plate 404 .
[0039] The rise of the valve plate 302 will drive the fixedly installed sliding rod 301 to move, and then the sliding rod 301 will drive the fixedly installed sliding plate 401 to move. At the same time, the sliding plate 401 will push the first triangular blocks 402 to move, and the sliding plate 401 will drive the moving rod 403 to move and the spring 405 to compress, and then the first triangular blocks 402 will push the corresponding second triangular blocks 502 to move, and then the second triangular blocks 502 will drive the driving disk 501 to move. Since the support plate 404 is provided with a sliding groove 406 slidably installed with the rotating rods 503, the driving disk 501 will then drive the slidably installed rotating rods 503 to rotate inside the sliding groove 406, and then the rotating rods 503 will drive the baffle plates 504 fixedly installed thereon to rotate, and then the baffle plates 504 will evenly approach each other and converge, and make the oil unloading channel of the entire valve body 1 in a closed state, thereby closing the oil unloading channel of the valve body 1.
[0040] Therefore, the rising of the valve plate 302 will cause the sealing ring 303 to be embedded in the outer shell 101, and the rising of the valve plate 302 will cause the plurality of rotating rods 503 to drive the respective baffle plates 504 to rotate, and then the plurality of baffle plates 504 will evenly approach and converge with each other, and the plurality of baffle plates 504 will evenly approach and converge with each other, so that the oil unloading channel of the entire valve body 1 is in a closed state, and then the oil unloading channel of the valve body 1 is closed, thereby preventing the leakage of gasoline and avoiding the phenomenon of gasoline leakage caused by only using a sealing ring for sealing and the sealing ring being prone to aging for a long time.
