Description

Technical Field

[0001] This application relates to the field of explosion-proof solenoid valves, and more particularly to a corrosion-resistant explosion-proof solenoid valve device. Background Technology

[0002] An explosion-proof solenoid valve encloses all components of an equipment that could ignite an explosive gas mixture within a sealed enclosure. This enclosure is designed to withstand the internal explosion of flammable mixtures that may penetrate through any joints or structural gaps without causing damage, and it will not ignite an external explosive atmosphere composed of one or more gases or vapors. Components that could generate sparks, arcs, or dangerous temperatures are placed within the explosion-proof enclosure, which isolates the internal space of the equipment from the surrounding environment. However, gaps exist within the explosion-proof enclosure, and due to the breathing effect of electrical equipment and gas permeation, an explosive gas mixture may remain inside. In conventional explosion-proof solenoid valves, after connecting the connecting pipe to a water source, the solenoid valve body is mounted on the top of the connecting pipe. The valve body controls the valve core within the solenoid valve body to control the opening and closing of the gas flow through the connecting pipe.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional explosion-proof solenoid valves are installed in various environments. In relatively humid environments, external moisture can easily enter improperly installed solenoid valves. Prolonged exposure to humid environments can cause corrosion of the internal components of the solenoid valve, thereby affecting its service life.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] A corrosion-resistant and explosion-proof solenoid valve device includes a solenoid valve body and a connecting box. A connecting pipe is fixedly connected to the bottom end of the solenoid valve body, and the connecting pipe is perpendicular to the solenoid valve body.

[0008] Preferably, two rotating shafts are rotatably mounted on the inner wall of the connecting plate. One end of each rotating shaft is fixedly connected to one end of the rotating blade and the dehumidifying fan blade, respectively.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a connecting box inside a connecting pipe, a rotating blade is rotatably connected to the inner wall of the connecting box. A dehumidifying fan blade is mounted on one end of the rotating blade via a connecting plate. A dehumidifying chamber is rotatably mounted on the surface of the dehumidifying fan blade, allowing the airflow within the connecting pipe to control the rotation of the rotating blade. The rotating blade, driven by the connecting plate, rotates the dehumidifying fan blade, creating airflow within the dehumidifying chamber, thereby dehumidifying the surface of the solenoid valve body. Two rotating shafts are rotatably connected to the inner wall of the connecting plate, and synchronous belts are mounted on the surfaces of the two shafts to improve the conversion efficiency of the rotating blade to the dehumidifying fan blade.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a corrosion-resistant and explosion-proof solenoid valve device, referring to... Figure 1 - Figure 2The system includes a solenoid valve body 1. In use, after connecting the connecting pipe 2 to the water source, the solenoid valve body 1 is installed on the top of the connecting pipe 2. The valve core inside the solenoid valve body 1 controls the opening and closing of the gas in the connecting pipe 2. The connecting box 3 is installed inside the connecting pipe 2. The inner wall of the connecting box 3 is rotatably connected to a rotating blade 4. One end of the rotating blade 4 is equipped with a dehumidifying fan blade 6 via a connecting plate 5. A dehumidifying box 7 is rotatably installed on the surface of the dehumidifying fan blade 6. The interior of the dehumidifying box 7 is installed on the surface of the solenoid valve body 1 so that the rotating blade 4 can be controlled to rotate by the airflow in the connecting pipe 2. The rotating blade 4 drives the dehumidifying fan blade 6 to rotate via the connecting plate 5, so that the dehumidifying fan blade 6 forms an airflow in the dehumidifying box 7. Thus, when the external humidity decreases, the airflow dehumidifies the surface of the solenoid valve body 1, effectively reducing power consumption and preventing moisture from corroding the components inside the solenoid valve body 1.

[0024] Reference Figure 2 Two rotating shafts 8 are rotatably connected to the inner wall of the connecting plate 5. One end of each rotating shaft 8 is connected to one end of the rotating blade 4 and the other end of the dehumidifying fan blade 6. A synchronous belt 9 is installed on the surface of each rotating shaft 8 to improve the conversion efficiency of the rotating blade 4 to the dehumidifying fan blade 6, thereby increasing the air volume generated by the dehumidifying fan blade 6. Several limiting grooves 10 are opened on the surface of the rotating shaft 8 to increase the friction between the rotating shaft 8 and the synchronous belt 9, avoiding slippage between the rotating shaft 8 and the synchronous belt 9. A bearing 11 is installed at one end of the dehumidifying fan blade 6, and one end of the bearing 11 is connected to the inside of the dehumidifying box 7 to reduce the friction between the dehumidifying fan blade 6 and the dehumidifying box 7, thereby ensuring the rotational stability of the dehumidifying fan blade 6.

[0025] Reference Figure 2 - Figure 4 Several mounting brackets 12 are installed at the bottom of the dehumidification box 7. The inner wall of the mounting bracket 12 is equipped with a shielding net 13 to shield the air outlet of the dehumidification box 7, preventing external impurities from entering the dehumidification box 7 and causing poor airflow. A rubber limiting block 14 is snapped onto the surface of the mounting bracket 12, and the surface of the limiting block 14 is fixedly connected to the surface of the dehumidification box 7. A control frame 15 is installed on the surface of the mounting bracket 12. Due to the relatively soft properties of the rubber material of the limiting block 14, the mounting bracket 12 can be easily removed from the limiting block 14 with the help of the control frame 15. This makes it easier to clean the shielding net 13. A rubber fixing ring 16 is installed on the top of the dehumidification box 7. The inner wall of the fixing ring 16 contacts the surface of the solenoid valve body 1, so as to increase the friction between the dehumidification box 7 and the solenoid valve body 1, thereby making the dehumidification box 7 more stable after installation and preventing the dehumidification box 7 from vibrating and generating noise.

[0026] The implementation principle of the corrosion-resistant and explosion-proof solenoid valve device in this application embodiment is as follows: A connecting box 3 is installed inside a connecting pipe 2. A rotating blade 4 is rotatably connected to the inner wall of the connecting box 3. A dehumidifying fan blade 6 is mounted on one end of the rotating blade 4 via a connecting plate 5. A dehumidifying box 7 is rotatably mounted on the surface of the dehumidifying fan blade 6. The interior of the dehumidifying box 7 is installed on the surface of the solenoid valve body 1, so that the rotation of the rotating blade 4 can be controlled by the airflow in the connecting pipe 2. The rotating blade 4 drives the dehumidifying fan blade 6 to rotate via the connecting plate 5, causing the dehumidifying fan blade 6 to form an airflow within the dehumidifying box 7, thereby dehumidifying the surface of the solenoid valve body 1, effectively reducing power consumption, and preventing moisture from corroding the components inside the solenoid valve body 1. The inner wall of the connecting plate 5 is rotatably connected to... Two rotating shafts 8 are provided, one end of which is connected to one end of the rotating blade 4 and the other end of the dehumidifying fan blade 6. Synchronous belts 9 are installed on the surface of the two rotating shafts 8 to improve the conversion efficiency of the rotating blade 4 to the dehumidifying fan blade 6, thereby increasing the air volume generated by the dehumidifying fan blade 6. Several limiting grooves 10 are opened on the surface of the rotating shafts 8 to increase the friction between the rotating shafts 8 and the synchronous belts 9, avoiding the problem of slippage between the rotating shafts 8 and the synchronous belts 9. A bearing 11 is installed at one end of the dehumidifying fan blade 6, and one end of the bearing 11 is connected to the inside of the dehumidifying box 7 to reduce the friction between the dehumidifying fan blade 6 and the dehumidifying box 7, thereby ensuring the rotational stability of the dehumidifying fan blade 6.

[0027] Several mounting brackets 12 can also be installed at the bottom of the dehumidification box 7. The inner wall of the mounting bracket 12 is equipped with a shielding net 13 to shield the air outlet of the dehumidification box 7, preventing external impurities from entering the dehumidification box 7 and causing poor airflow. A rubber limiting block 14 is snapped onto the surface of the mounting bracket 12, and the surface of the limiting block 14 is fixedly connected to the surface of the dehumidification box 7. A control frame 15 is installed on the surface of the mounting bracket 12. Due to the relatively soft properties of the rubber material of the limiting block 14, it is easy to remove the mounting bracket 12 from the limiting block 14 with the help of the control frame 15. It is also more convenient to clean the shielding net 13. A rubber fixing ring 16 is installed on the top of the dehumidification box 7. The inner wall of the fixing ring 16 contacts the surface of the solenoid valve body 1, so as to increase the friction between the dehumidification box 7 and the solenoid valve body 1, thereby making the dehumidification box 7 more stable after installation and preventing the dehumidification box 7 from vibrating and generating noise.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
