Description

Technical Field

[0001] This utility model relates to the field of valve fittings technology, specifically to a float assembly that can improve smoothness inside the valve body. Background Technology

[0002] The fuel limit valve (FLVV) is an important component of a vehicle's fuel system, primarily used to control fuel flow and prevent fuel spillage. The float's role within the valve is mainly in fuel level control. During refueling, as the fuel level rises, the float rises due to buoyancy, triggering a closing mechanism when it reaches a specific position.

[0003] Most existing valves are connected to the float in a sliding manner. The valve contacts the entire outer surface of the float and other parts to achieve the up-and-down sliding effect. Therefore, during operation, the float will move up and down due to gravity or buoyancy, causing collisions and noise, which can lead to a poor subjective experience for drivers and passengers. At the same time, with a large face-to-face contact, if the product appearance is not well finished, there may be jamming or poor sliding, which can indirectly lead to product failure. Utility Model Content

[0004] The purpose of this utility model is to provide a float assembly that can improve the smoothness inside the valve body, so as to solve the problem mentioned in the background art that the floats currently on the market are fixed in the valve by a surface-to-surface sliding connection, which can cause jamming due to product manufacturing problems, and cause the float to shake and generate noise during vehicle operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a float assembly that improves smoothness within a valve body, comprising a float assembly body, a float cylinder on the float assembly body, and a positioning protrusion integrally provided at even intervals on the upper end of the float cylinder; a float upper seat on the float assembly body, and a snap-fit ​​connector integrally provided on the side of the float upper seat to engage and securely fasten with the positioning protrusion; an upper sealing gasket fitted on the float upper seat, and a lower sealing gasket engaging with the upper end of the float cylinder to seal against the float upper seat; slots evenly spaced on the bottom side of the float cylinder, and I-shaped shock-absorbing pads respectively engaging in the slots; and a first rib and a second rib integrally provided on the outer side of the float cylinder, with the first rib and the second rib being smoothed.

[0006] Preferably, the first and second ribs are located on the outermost ring of the float assembly body, and the first and second ribs have the same cross-sectional dimensions. The outer surfaces of the first and second ribs are arc-shaped, and the first and second ribs are located above and below the sides of the float, respectively.

[0007] Preferably, the card slots are provided in three places, and the shape of the card slots on the side of the float is T-shaped.

[0008] Preferably, the depth below the T-shaped structure of the card slot is less than the height of the middle part of the shock-absorbing pad, and the depth above the T-shaped structure of the card slot is greater than the height of the structure above the shock-absorbing pad.

[0009] Preferably, the width of the slot on the outer side of the groove on the bottom surface of the float is smaller than the diameter of the middle part of the shock-absorbing pad.

[0010] Preferably, the shock-absorbing pad has a circular structure and is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The float assembly, which improves smoothness within the valve body, has three additional slots at its bottom to secure the I-shaped shock-absorbing pads, reducing noise. Simultaneously, raised ribs on the outer surface of the float cylinder provide smoother float sliding, eliminating the risk of jamming and improving the subjective experience for drivers and passengers. The float assembly, which improves smoothness within the valve body, has raised ribs at the upper and lower ends of the float cylinder, which reduces sliding resistance while ensuring the stability of the float's vertical movement. The T-shaped slots provide a secure fixation for the shock-absorbing pads, and the reduced outer width of the slot bottom opening prevents the shock-absorbing pads from falling off.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a float assembly that can improve smoothness inside a valve body, including a float assembly body 1, a float cylinder 2 on the float assembly body 1, and a positioning protrusion 10 integrally provided at evenly spaced intervals on the upper end of the float cylinder 2. The float assembly body 1 also has a float upper seat 6, and a snap-fit ​​connector 11 integrally provided on the side of the float upper seat 6 to engage and securely fasten with the positioning protrusion 10. An upper sealing gasket 7 is fitted onto the float upper seat 6, and a lower sealing gasket 8 is snapped onto the upper end of the float cylinder 2 to seal against the float upper seat 6. The bottom side of the float cylinder 2 has evenly spaced slots 4. The structure has three slots, with the slot 4 located on the side of the float 2 in a T-shape. This structure allows for the separate fixing of three shock-absorbing pads 5, enabling the pads 5 to provide shock absorption support for the float assembly body 1. Each slot 4 contains an I-shaped shock-absorbing pad 5. The shock-absorbing pads 5 are circular and made of rubber. This structure utilizes the shape of the shock-absorbing pads 5 for easy installation and fixing. The rubber material also provides elasticity, thus enhancing shock absorption. The depth of the bottom of the T-shaped structure of the slot 4 is less than the height of the middle part of the shock-absorbing pad 5. The depth of the T-shaped structure is greater than the height of the structure above the shock-absorbing pad 5. This structure allows the shock-absorbing pad 5 to move up and down under the positioning of the slot 4, providing space for the shock absorption of the shock-absorbing pad 5, and facilitating the snap-fit ​​positioning of the shock-absorbing pad 5. The outer side of the float 2 is also integrally provided with a first protruding rib 3 and a second protruding rib 9. The width of the slot 4 located on the bottom surface of the float 2 is smaller than the diameter of the middle part of the shock-absorbing pad 5. This structure can utilize the elasticity of the shock-absorbing pad 5 to allow the shock-absorbing pad 5 to be smoothly snapped into the slot 4. After the shock-absorbing pad 5 is snapped into the slot 4, it can prevent the shock-absorbing pad 5 from falling off, and the first protruding rib 3... The first rib 3 and the second rib 9 are smoothed by grinding and polishing. The first rib 3 and the second rib 9 are located on the outermost ring of the float assembly body 1, and the cross-sectional dimensions of the first rib 3 and the second rib 9 are the same. The outer surfaces of the first rib 3 and the second rib 9 are arc-shaped, and the first rib 3 and the second rib 9 are located above and below the side of the float 2, respectively. This structure can reduce the contact area between the float assembly body 1 and the valve body by the first rib 3 and the second rib 9, which can effectively reduce the sliding resistance, avoid the problem of the float assembly body 1 getting stuck, and ensure the reliability of the valve body function.

[0018] Working principle: When using this float assembly that improves smoothness inside the valve body, the float assembly body 1 is first assembled by the float cylinder 2 and the float upper seat 6 through the snap-fit ​​connection of the positioning protrusion 10 and the snap-fit ​​connector 11. The upper sealing gasket 7 plays the role of upper sealing on the float upper seat 6, and the lower sealing gasket 8 is between the float cylinder 2 and the float upper seat 6. The float assembly body 1 slides within the valve body through the cooperation of the first rib 3 and the second rib 9. The first rib 3 and the second rib 9 are smoothed to reduce sliding resistance and make the movement smoother. The bottom of the float assembly body 1 is elastically damped by the shock-absorbing pad 5 set below the float cylinder 2, which plays the role of noise reduction. The slot 4 positions the shock-absorbing pad 5 to prevent the shock-absorbing pad 5 from falling off, thus completing a series of operations.

[0019] Although the present invention 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 invention should be included within the protection scope of the present invention.
