Technical Field

[0001] This utility model belongs to the field of refueling equipment, specifically relating to an oil and gas recovery refueling nozzle and its housing. Background Technology

[0002] With the development of technology and the improvement of living standards, more and more cars are entering households. The continuous increase in the number of cars has led to the continuous expansion of gas station construction. A typical gas station includes underground fuel storage tanks and multiple refueling devices connected to the tanks. Each refueling device dispenses fuel to vehicles via a nozzle.

[0003] Gas stations present a complex environment with high temperatures and dust levels. During refueling, the soft rubber sleeve is frequently exposed to external factors such as oil and chemicals. Furthermore, frequent use, improper operation, and friction between the nozzle and the fuel tank opening can lead to aging and wear of the soft rubber sleeve. To address these technical issues, it is necessary to provide an anti-aging fuel nozzle housing with vapor recovery technology.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an oil and gas recovery refueling nozzle and housing to solve the problems of inconvenient assembly and easy aging of soft rubber sleeves in the prior art.

[0006] To achieve the above objectives, this utility model provides an oil and gas recovery refueling nozzle housing. The refueling nozzle includes a nozzle body, which includes a main valve assembly and a self-locking valve assembly. The housing is characterized in that it includes a main valve outer shell and a self-locking valve outer shell covering the main valve assembly and the self-locking valve assembly, and the self-locking valve outer shell has a rubber-coated protrusion.

[0007] In one or more embodiments of this utility model, the housing is a conductive plastic housing, which includes a first housing and a second housing that are interlocked with each other.

[0008] In one or more embodiments of the present invention, the gun body further includes a drive assembly for opening or closing the main valve assembly, and the self-locking valve assembly is disposed above the drive assembly for locking or unlocking the drive assembly.

[0009] In one or more embodiments of the present invention, the refueling nozzle includes a barrel assembly connected to the nozzle body, and the housing further includes a barrel outer shell partially covering the barrel assembly.

[0010] In one or more embodiments of the present invention, the refueling nozzle includes an oil and gas shroud connected to the nozzle body, and the nozzle barrel housing is at least partially pressed against the outer periphery of the oil and gas shroud near one end of the nozzle body.

[0011] In one or more embodiments of the present invention, the refueling nozzle includes a bow guard assembly, and the housing further includes a bow guard outer shell that partially covers the bow guard assembly.

[0012] In one or more embodiments of the present invention, the refueling nozzle includes a trigger assembly, one end of which is connected to the nozzle body and the other end is attached to the bow guard assembly.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0031] Combination Figure 1 , Figure 2The illustrated oil and gas recovery refueling nozzle and housing include a nozzle body 1, a nozzle barrel assembly 2, and a housing 6 disposed outside the nozzle body 1 and the nozzle barrel assembly 2. The nozzle body 1 generally includes an inlet end 14, an outlet end 15, a main valve assembly 7 and a self-locking valve assembly 8 formed between the inlet end 14 and the outlet end 15, and a drive assembly 9 for driving the main valve assembly 7 to open or close. The housing 6 covers the outside of the nozzle body 1 and includes a self-locking valve assembly housing 63 and a main valve housing 64 covering the main valve assembly 7 and the self-locking valve assembly 8. A rubber-coated protrusion 631 is formed on the self-locking valve assembly housing 63.

[0032] For ease of description, this embodiment uses Figure 1 , 2 The orientation of the vapor recovery refueling nozzle is shown to illustrate its vertical position. The self-locking valve assembly 8 is positioned above the drive assembly 7 and the main valve assembly 8; therefore, the self-locking valve housing 63 is also formed above the main valve housing 64 of the vapor recovery refueling nozzle and protrudes outwards. The rubber-coated protrusion 631 preferably covers the outwardly protruding upper surface of the self-locking valve assembly housing 63, protecting the self-locking valve assembly 8 and the self-locking valve assembly housing 63 from damage in the event of an accidental drop of the refueling nozzle. Specifically, the rubber-coated protrusion 631 is formed by coating the self-locking valve assembly housing 63 with rubber or other elastomers through physical or chemical methods, improving the housing's anti-aging properties.

[0033] In some embodiments, the oil and gas recovery refueling nozzle housing 6 further includes a barrel outer shell 65 that partially covers the outside of the nozzle assembly 2. Specifically, the barrel outer shell 65 covers the outside of the oil pipe of the nozzle assembly 2. An oil and gas shroud 5 is fitted onto the nozzle assembly 2. The barrel outer shell 65 is at least partially fitted onto the outer peripheral surface of one end of the oil and gas shroud 5, pressing against the outer periphery of the port of the oil and gas shroud 5 near the nozzle body 1 to fix the oil and gas shroud 5 and ensure the sealing and stability of the refueling nozzle, as well as its reliable operation. Simultaneously, this barrel outer shell 65 replaces the fixing component of the oil and gas shroud 5 in existing oil and gas recovery refueling nozzles, making the refueling nozzle structure simpler and easier to operate.

[0034] In some embodiments, a grip portion 641 is formed on the main valve housing 64. This grip portion 641 facilitates the user's grip when handling the fuel nozzle and provides a grip for the operator during refueling. At least a portion of the grip portion 641 is provided with a grip rubber coating, which has raised and recessed surfaces to increase friction. This grip rubber coating improves the comfort and friction of holding the fuel nozzle. The grip rubber coating and the raised rubber coating portion 631 are formed on the main valve housing 64 in the same manner. In some embodiments, the grip rubber coating and the raised rubber coating portion 631 are integrally formed.

[0035] According to one embodiment of this application, the nozzle body 1 can be cast, and the material of the nozzle body 1 is a metal or alloy such as aluminum or stainless steel. In order to reduce the environmental pollution caused by fuel evaporation, the vapor recovery refueling nozzle will recover the vapors volatilized in the fuel tank back into the refueling machine through the gas channel in the nozzle body 1, thereby reducing the emission of vapors.

[0036] The oil and gas recovery refueling nozzle housing 6 is a static-dissipating plastic housing. The plastic housing is made of conductive plastic, which is easy to process and has good conductivity and corrosion resistance. In some embodiments, the conductive plastic can be polypropylene (PP), polyethylene (PE), polystyrene (PS), etc., and conductivity can be improved by adding conductive agents (such as carbon black, carbon nanotubes, metal powders, etc.).

[0037] Furthermore, in conjunction with see Figure 4 , Figure 5 The oil and gas recovery refueling nozzle housing 6 also includes a bow guard shell 67 that partially covers the bow guard assembly 4. The bow guard shell 67 partially covers the bow guard assembly 4, which can ensure the stable installation of the bow guard assembly 4.

[0038] Furthermore, the oil and gas recovery refueling nozzle housing 6 also includes a trigger housing 68 that partially covers the trigger assembly 3. The trigger housing 68 covers one side of the trigger assembly 3, one end of which is connected to the nozzle body 1, and the other end is attached to the bow guard assembly 4.

[0039] See also Figure 3 Furthermore, to facilitate the assembly of the vapor recovery refueling nozzle and the processing of its housing, the vapor recovery refueling nozzle housing 6 includes a first housing 61 and a second housing 62 that interlock with each other. The first housing 61 and the second housing 62 are arranged symmetrically around the vapor recovery refueling nozzle. The first housing 61 has several first fixing holes for fixing, and the second housing 62 has several second fixing holes for fixing. During assembly, after installing each part of the vapor recovery refueling nozzle body into the correct assembly position on the first housing 61 or the second housing 62, the other half of the housing is fastened on and secured with fasteners to complete the assembly of the vapor recovery refueling nozzle and its housing.

[0040] This utility model's oil and gas recovery refueling nozzle housing is applicable to various oil and gas recovery refueling nozzles, combined with... Figure 1 , Figure 5As shown, the oil and gas recovery refueling nozzle generally includes a main valve assembly 7, a self-locking valve assembly 8, and a drive assembly 9, all located between the inlet end 14 and the outlet end 15 of the nozzle body 1. The main valve assembly 7 allows or prevents oil from passing through the nozzle body 1, and allows or prevents oil and gas recovery from passing through the nozzle body 1. The drive assembly 9 is connected to the main valve assembly 7, which is installed in the middle of the refueling nozzle and controls the opening and closing of the main valve assembly 7, thereby controlling the flow of oil and / or oil and gas. The main valve assembly 7 can control the flow of oil during refueling, achieving automatic stopping during the refueling process and preventing oil leakage to ensure smooth refueling. The self-locking valve assembly 8 locks the drive assembly 9. When the drive assembly 9 is locked, it pushes the main valve assembly 7 to open, making refueling available. When the drive assembly 9 is unlocked, it cannot control the opening and closing of the main valve assembly 7.

[0041] The refueling nozzle also includes a trigger assembly 3 located outside the nozzle body, which is connected to the drive assembly 9 via a converter for controlling the drive assembly 9. In some embodiments, the converter may be located outside the nozzle body, with one end connected to the trigger assembly 3 and the other end connected to the drive assembly 9 through an opening. In the locked state, when the trigger assembly 3 is pulled, the drive assembly 9 can be pushed via the converter, thereby controlling the main valve assembly 7.

[0042] The refueling nozzle also includes a hand guard assembly 4, which is located outside the trigger assembly 3 and detachably connected to the nozzle body 1, for hand protection during refueling. In some embodiments, the hand guard assembly 4 includes one or more pins for engaging the trigger assembly 3, allowing the operator to secure the trigger assembly 3 during refueling. Correspondingly, the trigger assembly 3 also includes a locking structure located at its rear, which can be pushed and inserted into the pins of the hand guard assembly 4 to provide different oil flow rates.

[0043] The gun body 1 also includes multiple chambers for accommodating the various components of the refueling gun, including but not limited to: a main valve assembly chamber for accommodating the main valve assembly 7, a drive assembly chamber for accommodating the drive assembly 9, a self-locking valve assembly chamber for accommodating the self-locking valve assembly 8, and a barrel assembly chamber for accommodating at least a portion of the barrel assembly 2.

[0044] The gun body 1 also includes an oil passage 10 between the main valve assembly chamber and the self-locking valve assembly chamber, and an oil-gas passage 11 between the self-locking valve assembly chamber and the barrel assembly chamber. Oil enters the self-locking valve assembly 8 through the oil passage 10, and the oil pressure provided by the oil can push the self-locking valve assembly 8 to lock the drive assembly 9, making it usable.

[0045] The nozzle assembly 2 of the fuel dispenser includes an air pipe and a liquid pipe, as well as a vapor shield 5 fitted over the air pipe. The vapor shield 5 seals the vehicle's fuel filler neck during refueling, allowing fuel vapor to enter the gap between the fuel pipe and the air pipe through the vapor shield 5, and then into the fuel vapor passage of the nozzle body 1, thus preventing fuel vapor leakage outside the gas station. The vapor shield 5 may integrate a vapor recovery switch valve, which controls the entry of fuel vapor into the gap between the fuel pipe and the air pipe.
