Description

Technical Field

[0001] This utility model relates to the field of oil valve technology, specifically to an oil valve with an easy-to-disassemble handwheel. Background Technology

[0002] Oil valves are key devices in the oil and gas industry used to control fluid flow. They control the direction, flow rate, and pressure of fluids to achieve the opening and closing, regulation, and safety protection of pipeline systems. Their core functions include connecting / cutting off media, preventing backflow, regulating pressure / flow, and ensuring the safe operation of pipelines or equipment under extreme conditions.

[0003] To prevent accidental opening, the handwheels of valves at the transition control points of oil pipelines are removed from the valve body after use by pipeline workers. The handwheels are only installed on the valve when it is to be operated. Existing handwheel connections are usually difficult to disassemble, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide an oil valve with a handwheel that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil valve with an easily detachable handwheel, comprising a valve body, a rotating column, and a handwheel assembly. Valve pipes are connected to both the left and right sides of the valve body, and a valve stem is rotatably mounted in the middle of the valve body. A rotating column is fixed to the top of the valve stem, and protrusions are integrally fixed to both the front and rear sides of the rotating column. A handwheel assembly is installed on the upper outer side of the rotating column, and the handwheel assembly includes an mounting cylinder, a docking groove, a handwheel body, and a positioning plate. A docking groove is provided on the inner side of the mounting cylinder, and the shape of the docking groove matches the shape of the rotating column and the protrusions. The handwheel body is fixed to the top of the mounting cylinder, and a positioning plate is fixed to the lower outer side of the mounting cylinder.

[0006] Furthermore, a rotating plate is fixed to the lower outer side of the rotating column, and positioning rods are fixed to the upper left and right sides of the rotating plate. The rotating plate and the top surface of the valve body are rotatably connected.

[0007] Furthermore, the vertical center line of the rotating plate coincides with the vertical center line of the positioning plate, and limit components are installed on the left and right sides of the rotating plate.

[0008] Furthermore, the limiting component includes an extension plate, a damping shaft, and a limiting baffle. The extension plate is fixedly connected to the rotating plate, and the limiting baffle is rotatably mounted on the upper side of the extension plate via the damping shaft.

[0009] Furthermore, the limiting baffle is located on the upper side of the positioning plate, and a rubber anti-slip layer is adhered to the lower side of the limiting baffle.

[0010] Furthermore, the handwheel assembly also includes positioning holes, with positioning holes provided on both the left and right sides of the positioning plate, and the positioning holes corresponding one-to-one with the positioning rods.

[0011] Furthermore, the handwheel assembly also includes a hinge and an extended lever arm, with extended lever arms rotatably connected to both lower sides of the handwheel body via hinges.

[0012] This utility model provides an oil valve with an easy-to-disassemble handwheel, which has the following advantages: This utility model is equipped with a rotating column and a limiting component. The two protrusions at the front and rear of the rotating column can engage with the docking groove of the mounting cylinder. During use, the rotating plate integrated with the rotating column can rotate synchronously. After the handwheel component is installed, the position of the limiting baffle can be adjusted by rotating the damping shaft, so that the rubber anti-slip layer on the lower side of the limiting baffle is in close contact with the upper side of the positioning plate, increasing the friction and keeping the positioning plate stable, thereby making it difficult for the handwheel component to move upward and fall off during rotation.

[0013] This utility model is equipped with a handwheel assembly. The mating groove of the mounting cylinder can be perfectly matched and installed on the outside of the rotating column and the protrusion. During installation, the circumferential angle can be quickly aligned. At the same time, the positioning hole of the positioning plate can be precisely engaged with the rotating plate and the positioning rod to achieve dual positioning. This enables convenient disassembly and assembly of the handwheel assembly, replacing the traditional threaded connection method. When disassembling, the limiting structure of the limiting component can be released and the handwheel can be pulled out axially. The rotation of the handwheel body can drive the rotation of the mounting cylinder, the rotating column and the valve stem, thereby facilitating the opening and closing of the internal flow channel of the valve body. The extended lever arm can be easily extended by rotating the hinge, making it easier to rotate the handwheel body more effortlessly when needed. Attached Figure Description

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figures 1-3 As shown, an oil valve with an easily detachable handwheel includes a valve body 1, a rotating column 6, and a handwheel assembly 9. Valve pipes 2 are connected to both the left and right sides of the valve body 1, and a valve stem 3 is rotatably mounted in the middle of the valve body 1. The rotating column 6 is fixed to the top of the valve stem 3, and protrusions 7 are integrally fixed to both the front and rear sides of the rotating column 6. A rotating plate 4 is fixed to the lower outer side of the rotating column 6, and positioning rods 5 are fixed to the upper left and right sides of the rotating plate 4. The rotating plate 4 is rotatably mounted to the top surface of the valve body 1. The vertical center line of the rotating plate 4 coincides with the vertical center line of the positioning plate 904. Limiting assemblies 8 are installed on the outer left and right sides of the rotating plate 4. The limiting assemblies 8 include an extension plate 801, a damping rotating shaft 802, and a limiting baffle 803. The extension plate 801 is connected to the rotating column 1. Plate 4 is fixedly connected, and a limiting baffle 803 is rotatably mounted on the upper side of the extension plate 801 via a damping shaft 802. The limiting baffle 803 is located on the upper side of the positioning plate 904, and a rubber anti-slip layer is bonded to the lower side of the limiting baffle 803. The front and rear protrusions 7 of the rotating column 6 can engage with the docking groove 902 of the mounting cylinder 901. During use, the rotating plate 4, which is integrated with the rotating column 6, can rotate synchronously. After the handwheel assembly 9 is installed, the position of the limiting baffle 803 can be adjusted by rotating the damping shaft 802, so that the rubber anti-slip layer on the lower side of the limiting baffle 803 is tightly attached to the upper side of the positioning plate 904, increasing the friction and keeping the positioning plate 904 stable, thereby making it difficult for the handwheel assembly 9 to move upward and fall off during rotation.

[0018] like Figures 2-4As shown, a handwheel assembly 9 is installed on the upper outer side of the rotating column 6. The handwheel assembly 9 includes a mounting cylinder 901, a docking groove 902, a handwheel body 903, and a positioning plate 904. The mounting cylinder 901 has a docking groove 902 on its inner side, and the shape of the docking groove 902 matches the shape of the rotating column 6 and the protrusion 7. The handwheel body 903 is fixed to the top of the mounting cylinder 901, and the positioning plate 904 is fixed to the lower outer side of the mounting cylinder 901. The handwheel assembly 9 also includes positioning holes 905. Positioning holes 905 are opened on both the left and right sides of the positioning plate 904, and the positioning holes 905 correspond one-to-one with the positioning rod 5. The handwheel assembly 9 also includes a hinge 906 and an extension arm 907. The lower sides of both sides of the handwheel body 903 are rotated by the hinge 906. The moving connection has an extended lever arm 907; the mating groove 902 of the mounting cylinder 901 can be perfectly matched and installed on the outside of the rotating column 6 and the protrusion 7, and the circumferential angle can be quickly aligned during installation. At the same time, the positioning hole 905 of the positioning plate 904 can be precisely engaged with the rotating plate 4 and the positioning rod 5 to achieve dual positioning, thereby enabling convenient disassembly and assembly of the handwheel assembly 9, replacing the traditional threaded connection method. When disassembling, the limiting structure of the limiting component 8 can be released and the handwheel can be pulled out axially. The rotation of the handwheel body 903 can drive the rotation of the mounting cylinder 901, the rotating column 6 and the valve stem 3, thereby facilitating the opening and closing of the internal flow channel of the valve body 1. The extended lever arm 907 can be easily unfolded by rotating the hinge 906, thus making it easier to rotate the handwheel body 903 when needed.

[0019] In summary, as Figures 1-4 As shown, this oil valve with an easy-to-disassemble handwheel can be used by first installing the handwheel assembly 9. During installation, the mating groove 902 of the mounting cylinder 901 can be perfectly matched and installed on the outside of the rotating column 6 and the protrusion 7. At the same time, the positioning hole 905 of the positioning plate 904 can be precisely engaged with the rotating plate 4 and the positioning rod 5 to achieve double positioning. This enables the convenient disassembly and assembly of the handwheel assembly 9, replacing the traditional threaded connection method. After the handwheel assembly 9 is installed, the position of the limit baffle 803 can be adjusted by rotating the damping shaft 802, so that the rubber anti-slip layer on the lower side of the limit baffle 803 is tightly attached to the upper side of the positioning plate 904, increasing the friction and keeping the positioning plate 904 stable. This makes it difficult for the handwheel assembly 9 to move upward and fall off during rotation. When in use, the rotation of the handwheel body 903 drives the rotation of the mounting cylinder 901, the rotating column 6, and the valve stem 3, thereby facilitating the opening and closing of the internal flow channel of the valve body 1. At this time, the rotating plate 4, which is integrated with the rotating column 6, can rotate synchronously, and the extended lever arm 907 can be extended through the rotating hinge 906, so that the handwheel body 903 can be rotated more easily when needed. Conversely, when disassembling, the limiting structure of the limiting component 8 can be released, and the mounting cylinder 901 can be directly pulled out along the axial direction. This completes the use process of the oil valve with a handwheel that is easy to disassemble.
