Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an electric valve with high safety. Background Art

[0002] As a key component in the fluid control system, the valve plays a crucial role in various industrial and civil fields. It ensures the normal operation of the system by regulating the flow rate, pressure, and direction of the fluid. To improve the operation convenience and automation level of the valve, modern valves generally adopt an electric controller to control the opening and closing. The electric controller can not only achieve remote control but also automatically execute the switch action according to the preset program, greatly improving the use efficiency and flexibility of the valve. In scenarios with high safety requirements, the application of electric valves is particularly extensive. As a core component, its reliability and stability have a decisive impact on the overall safety of the system. However, in the existing design of electric valves, the electric controller at the top is often directly exposed without effective protection. This design gradually exposes a series of obvious limitations and technical problems in actual use. Specifically, in the existing electric valves, the electric controller at the top is at risk of being damaged due to external force collision. Once the electric controller is damaged by an accidental impact, the entire valve will not be able to work properly, which will not only lead to the failure of the system fluid control but also may cause safety accidents. In addition, the exposed design of the electric controller also increases the possibility of being affected by the harsh environment, further reducing the reliability and service life of the valve. More seriously, these problems not only significantly increase the cost of maintaining and replacing the controller but also may pose a potential threat to the overall safety and stability of the system.

[0003] Therefore, in view of the many deficiencies in the prior art, we urgently need a highly secure electric valve to solve these problems. This new type of highly secure electric valve should be able to effectively protect the electric controller at the top, prevent it from being damaged due to external force collision, and at the same time improve the overall reliability and service life of the valve. In addition, the new electric valve should also have better environmental adaptability to meet the usage requirements under various complex working conditions and provide strong support for the safe and stable operation of the fluid control system.

Detailed Embodiment

[0022] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Referring to Figures 1-5 , a highly secure electric valve, comprising a valve 1 and a controller 4. The controller 4 is connected to the top of the valve 1 through a connecting pipe 3. Two protective covers 2 are symmetrically arranged outside the controller 4. Both protective covers 2 are semi-cylindrical. The two protective covers 2 form an entire cylinder. A plurality of ventilation slots 12 for ventilation are provided on the outer ring of the protective cover 2;

[0024] The bottom of the protective cover 2 is detachably connected with a semi-circular supporting plate 7. A semi-circular groove adapted to the outer ring of the connecting pipe 3 is provided at the center of one side of the supporting plate 7. The bottom of the supporting plate 7 is connected with a bottom ring plate 9 detachably connected to the outer ring of the connecting pipe 3.

[0025] The following is the working process of this solution:

[0026] This highly secure electric valve mainly consists of two major parts: a valve 1 and a controller 4. The controller 4 is tightly connected to the top of the valve 1 through a connecting pipe 3, ensuring the accurate transmission of control instructions. In order to protect the controller 4 from external forces, two semi-cylindrical protective covers 2 are specially designed. These two protective covers 2 are symmetrically arranged and can form a complete cylinder, tightly wrapping the controller 4 inside. A plurality of ventilation slots 12 are also provided on the outer ring of the protective cover 2. These ventilation slots 12 not only ensure good ventilation of the controller 4 during operation but also avoid heat dissipation problems caused by overly tight enclosure.

[0027] At the bottom of the protective cover 2, a detachable semi-circular supporting plate 7 is designed. A semi-circular groove adapted to the outer ring of the connecting pipe 3 is accurately provided at the center of one side of the supporting plate 7. This design not only facilitates installation but also enhances the stability between the connecting pipe 3 and the protective cover 2. The bottom of the supporting plate 7 is further connected with a bottom ring plate 9, and the bottom ring plate 9 is also detachably connected to the outer ring of the connecting pipe 3. Such a double fixation design greatly improves the stability and security of the entire structure of the electric valve.

[0028] When the electric valve is operating, the controller 4 receives instructions from a remote location or a preset program, and transmits control signals to the valve 1 through the connecting pipe 3 to achieve precise opening or closing of the valve. During the entire process, the protective cover 2 and the supporting plate 7 and the bottom ring plate 9 at its bottom together form a solid protective layer, effectively resisting external collisions and the influence of harsh environments, and ensuring the normal operation of the controller 4 and the entire electric valve.

[0029] Furthermore, a number of connecting holes are provided on the side wall of the bottom ring plate 9, and a number of positioning holes 5 are provided on the outer ring of the connecting pipe 3. A positioning screw 6 adapted to the connecting hole is threadedly connected inside each positioning hole 5. Through the connecting holes on the side wall of the bottom ring plate 9, the positioning holes 5 on the outer ring of the connecting pipe 3, and the positioning screws 6 threadedly connected inside each positioning hole 5, during the installation process, the positioning screw 6 can pass through the connecting hole and be screwed into the positioning hole 5, realizing a firm connection between the bottom ring plate 9 and the connecting pipe 3. This design not only enhances the stability of the entire electric valve structure but also ensures that the protective cover 2 and its bottom components will not loosen due to vibration or external forces during long-term use, thus effectively protecting the safety of the controller 4 and improving the reliability and service life of the electric valve.

[0030] Furthermore, an installation semi-circular plate 11 is fixedly connected to the bottom edge of the protective cover 2. The installation semi-circular plate 11 is bolted and fixed to the top of the supporting plate 7. Through the setting that the installation semi-circular plate 11 fixedly connected to the bottom edge of the protective cover 2 is bolted and fixed to the top of the supporting plate 7, when installing and disassembling the protective cover 2, only by tightening or loosening the bolts can the connection and separation between the protective cover 2 and the supporting plate 7 be easily realized. This design simplifies the installation process, improves the maintenance efficiency, and at the same time ensures the tightness and stability of the connection between the protective cover 2 and the supporting plate 7, providing reliable protection for the controller 4.

[0031] Furthermore, side plates 8 are fixedly connected to both sides of the adjacent sides of the two supporting plates 7. The two adjacent side plates 8 are connected by a connecting screw 10. Through the side plates 8 on the adjacent sides of the two supporting plates 7 and the setting that the two adjacent side plates 8 are connected by a connecting screw 10, during the assembly process, the connecting screw 10 can pass through the adjacent side plates 8 and tightly fix them together, thereby enhancing the connection strength between the supporting plates 7 and the stability of the entire electric valve structure. This design effectively prevents the supporting plates 7 from deforming or shifting due to uneven stress during use, ensuring the normal operation of the controller 4 and the entire electric valve.

[0032] Furthermore, an arc-shaped protective plate 13 is detachably connected to one side of the protective cover 2. The arc-shaped protective plate 13 is made of rubber material, and a number of heat dissipation grooves are provided on one side of the arc-shaped protective plate 13. Through the arc-shaped protective plate 13 detachably connected to one side of the protective cover 2, and the setting that the arc-shaped protective plate 13 is made of rubber material and provided with a number of heat dissipation grooves, while protecting the controller 4 from external forces, the rubber arc-shaped protective plate 13 also has a certain elasticity and buffering effect, which can further reduce the impact of external forces on the controller 4. At the same time, the design of the heat dissipation grooves ensures good ventilation and heat dissipation of the controller 4 during operation, avoiding performance degradation or damage caused by overheating, and improving the reliability and service life of the electric valve.

[0033] Furthermore, fixed blocks 15 are fixedly connected to both sides of the protective cover 2. A plugging groove 14 adapted to the side wall of the arc-shaped protection plate 13 is formed on one side of the fixed block 15. Through the fixed blocks 15 fixedly connected to both sides of the protective cover 2 and the plugging groove 14 formed on one side of the fixed block 15 and adapted to the side wall of the arc-shaped protection plate 13, when installing the arc-shaped protection plate 13, it only needs to insert its side wall into the plugging groove 14 to achieve firm connection. This design not only simplifies the installation process, but also improves the tightness and stability of the connection between the arc-shaped protection plate 13 and the protective cover 2, providing more comprehensive and reliable protection for the controller 4.

[0034] In summary: The design of this high-security electric valve completely integrates the two core components of the valve 1 and the controller 4, and realizes their close connection through the connecting pipe 3, ensuring the accurate transmission of control instructions. The working principle and beneficial effects of the entire valve system are as follows:

[0035] The valve 1, as an actuator for fluid control, receives signal instructions from the controller 4 to achieve precise opening or closing actions. The controller 4 is responsible for receiving instructions from remote or preset programs and transmitting control signals to the valve 1 through the connecting pipe 3. To protect this key component from external forces, two semi-cylindrical protective covers 2 are specially designed. They are symmetrically arranged and can form a complete cylinder, tightly wrapping the controller 4. This design significantly reduces the risk of damage caused by external impacts, thus ensuring the normal operation of the valve and avoiding system fluid control failure and safety accidents caused by controller damage. A number of through slots 12 are opened on the outer ring of the protective cover 2. These through slots 12 ensure good ventilation during the operation of the controller 4 while avoiding overheating problems caused by a closed environment, effectively improving the service life of the controller 4 and the entire electric valve. To further enhance the structural stability, a semi-circular supporting plate 7 is detachably connected to the bottom of the protective cover 2. A semi-circular groove adapted to the outer ring of the connecting pipe 3 is precisely opened at the center of one side of the supporting plate 7, facilitating installation and enhancing the stability between the connecting pipe 3 and the protective cover 2. The bottom of the supporting plate 7 is further connected to a bottom ring plate 9, and the bottom ring plate 9 is also detachably connected to the outer ring of the connecting pipe 3. A number of connecting holes are opened on the side wall of the bottom ring plate 9, which cooperate with the positioning holes 5 on the outer ring of the connecting pipe 3. A positioning screw 6 adapted to the connecting hole is threadedly connected inside each positioning hole 5. During installation, the positioning screw 6 can pass through the connecting hole and be screwed into the positioning hole 5, achieving a firm connection between the bottom ring plate 9 and the connecting pipe 3. This dual fixation design greatly improves the stability and safety of the entire electric valve structure. To simplify the installation process and improve the maintenance efficiency, an installation semi-circular plate 11 is fixedly connected to the bottom edge of the protective cover 2, and the installation semi-circular plate 11 is fixedly connected to the top of the supporting plate 7 through bolts. By simply tightening or loosening the bolts, the connection and separation between the protective cover 2 and the supporting plate 7 can be easily achieved. At the same time, side plates 8 are fixedly connected to both sides of the two supporting plates 7 close to each other, and the two adjacent side plates 8 are connected by a connecting screw 10, enhancing the connection strength between the supporting plates 7 and the stability of the entire electric valve structure, effectively preventing the supporting plates 7 from deforming or shifting due to uneven force during use. In addition, an arc-shaped protective plate 13 is detachably connected to one side of the protective cover 2. The arc-shaped protective plate 13 is made of rubber material and is provided with a number of heat dissipation slots. This design not only protects the controller 4 from external forces but also has a certain elastic and buffering effect, which can further reduce the impact of external forces on the controller 4. The design of the heat dissipation slots ensures good ventilation and heat dissipation of the controller 4 during operation, avoiding performance degradation or damage caused by overheating. To facilitate the installation of the arc-shaped protective plate 13, fixing blocks 15 are fixedly connected to both sides of the protective cover 2, and a plug-in slot 14 adapted to the side wall of the arc-shaped protective plate 13 is opened on one side of the fixing block 15.When installing the arc-shaped protection plate 13, simply insert its side wall into the insertion slot 14 to achieve a firm connection, which simplifies the installation process and improves the tightness and stability of the connection between the arc-shaped protection plate 13 and the protective cover 2.

[0036] This high-security electric valve design effectively solves many deficiencies in the prior art through a series of innovative structural designs and optimizations. It not only improves the overall performance and service life of the valve but also reduces the costs of maintaining and replacing the controller. At the same time, this design also enhances the environmental adaptability of the electric valve, enabling it to maintain stable working performance under various complex working conditions, providing strong support for the safe and stable operation of the fluid control system. During the operation of the entire valve system, each component works together to jointly form a solid protective layer, effectively resisting the impact of external forces and the influence of harsh environments, ensuring the normal operation of the controller 4 and the entire electric valve.
