Description

Technical Field

[0001] This invention relates to the field of electric valve technology, specifically to a marine electric valve that can prevent electric actuator jamming. Background Technology

[0002] Marine valves are devices used to control the pressure, flow rate, and flow direction of fluids within ship pipelines, designed to meet the environmental conditions of ships. Valves are control devices for fluid pipelines; their basic functions are to connect or disconnect the flow of media, change the flow rate, change the flow direction, regulate the pressure and flow rate, and protect the normal operation of pipeline equipment. Electric valves have a greater operating torque than ordinary valves, and their opening and closing speeds are adjustable. They are simple in structure and easy to maintain. However, due to the long-term corrosive effects of substances within the pipeline, existing electric valves are prone to jamming during operation due to friction with the pipeline, leading to actuator seizure and affecting the service life of the electric valves.

[0003] Therefore, the present invention provides a marine electric valve that can prevent the electric actuator from jamming. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a marine electric valve that prevents the electric actuator from jamming, thereby solving the problems mentioned in the background art. The present invention can drive the slider to slide through the electric actuator, thereby causing the slider to be misaligned with the valve plate, which can assist in opening the valve and prevent the valve plate from jamming, thus preventing the electric actuator from jamming. Furthermore, if the electric actuator jams, the valve plate can be opened through the auxiliary anti-jamming structure, extending the service life of the valve.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a marine electric valve that can prevent electric actuator jamming, comprising a butterfly valve and an electric actuator, wherein the butterfly valve comprises a valve body, a valve stem is rotatably fitted inside the valve body, a valve plate is fixed on the valve stem, and sliders are slidably fitted on both sides of the valve body, the sliders corresponding to the valve plate, a transmission structure is installed between the electric actuator and one of the sliders, the electric actuator corresponding to the valve stem, and an auxiliary anti-jamming structure is installed on one side of the valve body, the auxiliary anti-jamming structure corresponding to the other slider.

[0006] Furthermore, the butterfly valve has a first sliding groove on both sides, which corresponds to the slider. The butterfly valve also has a through groove that is connected to the first sliding groove.

[0007] Furthermore, the width of the slider is twice the width of the through slot.

[0008] Furthermore, multiple springs are fixed between the first groove and the slider.

[0009] Furthermore, the electric actuator includes a motor and a rotating shaft, the rotating shaft being fixedly connected to the valve stem, and an output shaft being fixed to the output end of the motor.

[0010] Furthermore, a first gear is fixed on the output shaft, and a second gear is fixed on the rotating shaft, with the second gear meshing with the first gear.

[0011] Furthermore, the transmission structure includes a connecting rod, a slide bar is fixed on one of the sliders, the slide bar is fixedly connected to the connecting rod, and a connecting shaft is installed between the connecting rod and the output shaft.

[0012] Furthermore, a second slide groove is provided on the lower side of the electric actuator, the second slide groove corresponds to the connecting rod, a fixing plate is fixed to the end of the output shaft, and the connecting shaft is rotatably connected to the fixing plate and the connecting rod.

[0013] Furthermore, the auxiliary anti-jamming structure includes an electric cylinder, the output end of which is fixed with a fixing rod, which is fixedly connected to another slider.

[0014] Furthermore, the slider has a semi-circular structure and is made of rubber material.

[0015] The beneficial effects of the present invention: The present invention provides a marine electric valve that can prevent electric actuator jamming, comprising a valve body; a slider; an electric actuator; a transmission structure; a valve plate; and an auxiliary anti-jamming structure.

[0016] Sliders are installed on both sides of the valve body, and a transmission structure is installed between the electric actuator and one of the slides. The electric actuator can drive the slide to slide, thereby causing the slide to be misaligned with the valve plate, which can help open the valve and prevent the valve plate from jamming, thus preventing the electric actuator from jamming. An auxiliary anti-jamming structure is installed on one side of the valve body. If the electric actuator jams, the valve plate can be opened through the auxiliary anti-jamming structure, thus extending the service life of the valve. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a marine electric valve that can prevent electric actuator jamming, comprising a butterfly valve 1 and an electric actuator 5. The butterfly valve 1 includes a valve body 2, a valve stem 3 rotatably fitted inside the valve body 2, a valve plate 4 fixed on the valve stem 3, and sliders 18 slidably fitted on both sides inside the valve body 2, the sliders 18 corresponding to the valve plate 4. A transmission structure is installed between the electric actuator 5 and one of the sliders 18, the electric actuator 5 corresponding to the valve stem 3, and an auxiliary anti-jamming structure 20 is installed on one side of the valve body 2, the auxiliary anti-jamming structure 20 corresponding to the other slider 18.

[0026] In this embodiment, a first slide groove 14 is provided on both sides of the butterfly valve 1. The first slide groove 14 corresponds to the slider 18. A through groove 17 is provided in the butterfly valve 1. The through groove 17 is connected to the first slide groove 14. The width of the slider 18 is twice the width of the through groove 17. A plurality of springs 19 are fixed between the first slide groove 14 and the slider 18.

[0027] Specifically, when the valve is opened, the valve plate 4 rotates and the slider 18 slides, causing the slider 18 to be misaligned with the valve plate 4, thus opening the valve plate 4. When the valve plate 4 is stuck, the slider 18 slides, creating a gap between the slider 18 and the valve plate 4, which helps to open the valve plate 4.

[0028] The electric actuator 5 includes a motor 6 and a rotating shaft 10. The rotating shaft 10 is fixedly connected to the valve stem 3. An output shaft 7 is fixed to the output end of the motor 6. A first gear 8 is fixed on the output shaft 7. A second gear 9 is fixed on the rotating shaft 10. The second gear 9 meshes with the first gear 8. The transmission structure includes a connecting rod 13. A sliding rod 16 is fixed on one of the sliders 18. The sliding rod 16 is fixedly connected to the connecting rod 13. A connecting shaft 11 is installed between the connecting rod 13 and the output shaft 7. A second sliding groove 15 is opened on the lower side of the electric actuator 5. The second sliding groove 15 corresponds to the connecting rod 13. A fixing plate 12 is fixed to the end of the output shaft 7. The connecting shaft 11 is rotatably connected to the fixing plate 12 and the connecting rod 13.

[0029] Specifically, when it is necessary to open the valve plate 4, the motor 6 is started, so that the output end of the motor 6 drives the output shaft 7 to rotate, so that the first gear 8 and the second gear 9 mesh and rotate, thereby driving the rotating shaft 10 to rotate. The rotating shaft 10 drives the valve stem 3 to rotate, and at the same time the output shaft 7 drives the fixed plate 12 to rotate, so that the fixed plate 12 can push and pull the connecting rod 13 through the connecting shaft 11, thereby driving the slider 18 to slide back and forth.

[0030] The auxiliary anti-jamming structure 20 includes an electric cylinder 22. A fixing rod 21 is fixed to the output end of the electric cylinder 22. The fixing rod 21 is fixedly connected to another slider 18. The slider 18 has a semi-circular structure and is made of rubber material.

[0031] Specifically, when the electric actuator 5 is stuck, the electric cylinder 22 is activated, causing the electric cylinder 22 to drive another slider 18 to slide, thereby creating a gap between the slider 18 and the valve plate 4. This helps to open the valve plate 4 when the electric actuator 5 is stuck, thus extending the service life of the device.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
