Description
Technical Field
[0001] This utility model relates to the technical field of fuel tank accessories, specifically to an external oil-gas separation and venting tipper valve. Background Technology
[0002] Traditional oil-gas separation venting tipple valves are mostly located inside the fuel tank, used for venting while preventing oil leakage when the vehicle is bumpy or tipped over.
[0003] However, because it is located inside the fuel tank, it not only occupies valuable fuel tank volume, reducing the amount of fuel stored in the tank, but also makes maintenance inconvenient.
[0004] Therefore, we propose an external oil-gas separation venting tipper valve that does not require occupying the storage volume of the fuel tank. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an external oil-gas separation and venting tipper valve that does not require the storage volume of an oil tank and is convenient for maintenance.
[0006] This utility model provides an external oil-gas separation venting tipper valve, comprising: a cavity, an anti-impact mesh plate, a spring, a sealing gasket, and a piston; the cavity includes a main cavity pipe, an exhaust pipe end cap, and an oil inlet dual pipe end cap; the exhaust pipe end cap is installed at one end of the main cavity pipe, and the oil inlet dual pipe end cap is installed at the other end of the main cavity pipe; the exhaust pipe end cap is provided with an exhaust pipe; the exhaust pipe communicates with an external carbon canister; the oil inlet dual pipe end cap is provided with an inlet pipe and an outlet pipe; the oil inlet dual pipe end cap communicates with an oil tank through the inlet pipe and the outlet pipe; the piston is installed on the... The main cavity tube is described above; the sealing gasket is installed at one end of the piston, and the sealing gasket is located near the outlet pipe end cap; the sealing gasket abuts against the opening of the outlet pipe end cap; the anti-impact mesh plate is installed in the main cavity tube, near the oil inlet double pipe end cap; the anti-impact mesh plate has at least one through hole; one end of the spring is installed at the piston, and the other end of the spring is located on the anti-impact mesh plate; wherein the oil passes through the through hole and submerges the bottom of the piston; and flows towards the outlet pipe along the inlet pipe direction of the oil inlet double pipe end cap.
[0007] Furthermore, the oil inlet dual-pipe end cap also includes a mounting block; the mounting block is located inside the main cavity pipe and fixedly installed inside the main cavity pipe; the mounting block is provided with a mounting ring groove; the anti-impact mesh plate is detachably installed on the mounting block through the mounting ring groove. In practical applications, the purpose of this design is to facilitate the installation of the spring and the anti-impact mesh plate, thus making it easy to install and fix the spring and the anti-impact mesh plate.
[0008] Furthermore, the mounting block is also provided with a fixing groove, and the piston is also provided with a fixing deep groove; one end of the spring is installed on the fixing groove, and the other end of the spring is installed in the fixing deep groove. In practical applications, the purpose of this design is to facilitate the fixing of the spring and achieve effective connection to the piston.
[0009] Furthermore, the piston has a conical cylindrical shape. In practical applications, the piston end face area near the spring is larger than the piston end face area near the sealing gasket. This results in greater buoyancy at the bottom when submerged in oil, leading to greater stability and more stable piston movement within the main chamber.
[0010] Furthermore, the piston is also equipped with guide supports, which are provided in multiple locations and evenly distributed along the axial direction of the piston. In practical applications, the purpose of this design is to prevent the piston from swaying under the buoyancy of the oil. By abutting against the inner wall of the mounting main chamber, the swaying distance is effectively reduced. At the same time, the evenly distributed guide supports further ensure overall stability.
[0011] Furthermore, the guide support has at least one flow groove. In practical applications, the purpose of this design is to reduce the impact of oil / gas flow or liquid flow on the guide support. The flow groove reduces the impact area between the guide support and the oil / gas flow or liquid flow, effectively avoiding piston swaying after impact and further improving stability.
[0012] Furthermore, the piston is also provided with a mounting post, which is located on the end face of the piston and in a direction away from the spring; the sealing gasket is detachably mounted on the mounting post; wherein the sealing gasket movably abuts against the inner wall of the exhaust pipe end cap. In practical applications, the purpose of this mounting post design is to facilitate the installation of the sealing gasket and to facilitate the achievement of a sealing effect.
[0013] Furthermore, the sealing gasket is bowl-shaped and adheres to the inner wall of the outlet pipe end cap after contact. In practical applications, the purpose of this design is to achieve adsorption and fixation, thereby facilitating the effective flow of oil through the oil inlet dual-pipe end cap.
[0014] As can be seen from the above technical solution, the beneficial effects of the external oil-gas separation and venting tipper valve provided by this utility model are as follows:
[0015] In practical applications, the outlet of the vent pipe end cap is connected to a carbon canister, which is a carbon canister that is designed to prevent direct contact with the atmosphere and is used to adsorb oil and gas. The inlet and outlet pipes are connected to and communicate with the oil tank.
[0016] In the venting state, the spring force is insufficient to support the piston's weight, and the piston is at the bottom. Oil vapor enters from the inlet and outlet pipes, passes through the chamber where the main chamber pipe is installed, and exits from the outlet pipe.
[0017] When a large amount of fuel is being introduced, the piston is at the top under the action of the spring force and the buoyancy of the gasoline, and the exhaust pipe is closed by the sealing gasket to prevent gasoline from overflowing from the exhaust pipe;
[0018] Furthermore, the piston's weight is slightly greater than the spring force, ensuring that it is at the bottom when there is no gasoline buoyancy, and at the top when there is both spring force and gasoline buoyancy.
[0019] At the same time, the anti-impact mesh plate prevents gasoline from entering the chamber too quickly, faster than the piston's response time to the top, which could cause gasoline to overflow.
[0020] Therefore, the design is reasonable overall and easy to operate, effectively reducing the volume occupied by the fuel tank. Due to its external design, it is convenient for installation and maintenance. Attached Figure Description

Detailed Implementation
[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0029] The basic implementation examples are as follows: Figures 1 to 4 As shown:
[0030] like Figure 1-4 As shown in the figure, this embodiment provides an external oil-gas separation venting tipper valve that does not occupy the storage volume of the oil tank and is convenient for maintenance.
[0031] This utility model provides an external oil-gas separation venting tipper valve, comprising: a cavity 1, an anti-impact mesh plate 2, a spring 3, a sealing gasket 4, and a piston 5; the cavity 1 includes a main cavity pipe 11, an exhaust pipe end cap 12, and an oil inlet dual pipe end cap 13; the exhaust pipe end cap 12 is installed at one end of the main cavity pipe 11, and the oil inlet dual pipe end cap 13 is installed at the other end of the main cavity pipe 11; the exhaust pipe end cap 12 is provided with an exhaust pipe 121; the exhaust pipe 121 communicates with an external carbon canister; the oil inlet dual pipe end cap 13 is provided with an inlet pipe 131 and an outlet pipe 132; the oil inlet dual pipe end cap 13 communicates with an oil tank through the inlet pipe 131 and the outlet pipe 132; Piston 5 is installed inside the main chamber tube; sealing gasket 4 is installed at one end of piston 5, and sealing gasket 4 is located near the outlet pipe end cap 12; sealing gasket 4 abuts against the opening of the outlet pipe end cap 12; anti-impact mesh plate 2 is installed in the main chamber tube, and is located near the oil inlet double pipe end cap 13; anti-impact mesh plate 2 is provided with at least one through hole 201; one end of spring 3 is installed at piston 5, and the other end of spring 3 is located on anti-impact mesh plate 2; wherein oil passes through the through hole 201 and immerses the bottom of piston 5; and flows along the inlet pipe 131 of oil inlet double pipe end cap 13 towards outlet pipe 132.
[0032] In this embodiment, the oil inlet dual-pipe end cap 13 further includes a mounting block 133; the mounting block 133 is located inside the main cavity pipe and is fixedly installed inside the main cavity pipe; the mounting block 133 is provided with a mounting ring groove 1331; the anti-impact mesh plate 2 is detachably installed on the mounting block 133 through the mounting ring groove 1331. In practical applications, the purpose of this design is to facilitate the installation of the spring 3 and the anti-impact mesh plate 2, thus making it easy to install and fix the spring 3 and the anti-impact mesh plate 2.
[0033] In this embodiment, the mounting block 133 is further provided with a fixing groove 1332, and the piston 5 is further provided with a fixing deep groove 51; one end of the spring 3 is installed on the fixing groove 1332, and the other end of the spring 3 is installed in the fixing deep groove 51. In practical applications, the purpose of this design is to facilitate the fixing of the spring 3 and achieve effective connection to the piston 5.
[0034] In this embodiment, the piston 5 is shaped like a conical cylinder. In practical applications, the end face area of the piston 5 near the spring 3 is larger than that of the piston 5 near the sealing gasket 4. This results in greater buoyancy at the bottom when submerged in oil, thus improving stability and making the movement of the piston 5 within the main cavity tube 11 more stable.
[0035] In this embodiment, the piston 5 is further provided with guide supports 52. Multiple guide supports 52 are provided and evenly distributed along the axial direction of the piston 5. In practical applications, the purpose of this design is to prevent the piston 5 from swaying under the buoyancy of the oil. The contact between the guide supports 52 and the inner wall of the mounting main cavity tube 11 effectively reduces the swaying distance. Furthermore, the evenly distributed guide supports 52 further ensure overall stability.
[0036] In this embodiment, the guide bracket 52 has at least one flow groove 521. In practical applications, the purpose of this design is to reduce the impact of oil flow or liquid flow on the guide bracket 52. The flow groove 521 reduces the impact area between the guide bracket 52 and the oil flow or liquid flow, effectively avoiding piston 5 shaking after impact and further improving stability.
[0037] In this embodiment, the piston 5 is further provided with a mounting post 53, which is located on the end face of the piston 5 and in a direction away from the spring 3; the sealing gasket 4 is detachably mounted on the mounting post 53; wherein the sealing gasket 4 is in movable contact with the inner wall of the exhaust pipe end cap 12. In practical applications, the purpose of the mounting post 53 is to facilitate the installation of the sealing gasket 4 and to facilitate the sealing effect.
[0038] In this embodiment, the sealing gasket 4 is bowl-shaped and adheres to the inner wall of the vent pipe end cap 12 after contact. In practical applications, the purpose of this design is to achieve adsorption and fixation, thereby facilitating the effective flow of oil through the oil inlet dual-pipe end cap 13.
[0039] In actual operation, the outlet pipe 121 of the outlet pipe end cap 12 is connected to the carbon canister, which is a carbon canister that avoids direct ventilation with the atmosphere and is used to adsorb oil and gas. The inlet pipe 131 and the outlet pipe 132 are connected to and communicate with the oil tank.
[0040] In the ventilated state, the spring force of spring 3 is insufficient to support the weight of piston 5, and piston 5 is at the bottom. Oil vapor enters from the inlet pipe 131 and outlet pipe 132, passes through the chamber where the main chamber pipe 11 is installed, and exits from the outlet pipe 121.
[0041] When a large amount of oil is being introduced, piston 5 is at the top under the action of spring 3 and gasoline buoyancy, and the gasket 4 closes the exhaust pipe 121 to prevent gasoline from overflowing from the exhaust pipe 121.
[0042] Furthermore, the weight of piston 5 is slightly greater than the elastic force of spring 3, ensuring that it is at the bottom when there is no gasoline buoyancy, and at the top when there is both the elastic force of spring 3 and the gasoline buoyancy. At the same time, the anti-impact mesh plate 2 prevents gasoline from entering the chamber too quickly, faster than the response time of piston 5 reaching the top, which would cause gasoline to overflow.
[0043] In summary, this external oil-gas separation and venting tipper valve has a reasonable overall design and is easy to operate, effectively reducing the volume occupied by the oil tank. Due to its external design, it is convenient to install and maintain. Therefore, this device is suitable for industry promotion.
