Description

Technical Field

[0001] This utility model relates to the field of breather valve technology, specifically a breather valve for oil tanks with an intelligent temperature control and de-icing structure. Background Technology

[0002] The breather valve of an oil tank is an important safety accessory. Its function is to regulate the pressure balance inside and outside the tank and prevent damage caused by overpressure or vacuum. In cold environments, ice can easily form inside the breather valve, causing blockage and preventing the tank from regulating pressure properly. In severe cases, this can lead to tank deformation or even explosion.

[0003] Currently, some oil tank breather valves are manually inspected and de-iced periodically, but this method suffers from poor timeliness and high labor intensity. Others use electric heating belts or other methods for heating and de-icing, but these methods are usually continuous heating, which not only wastes energy but may also damage the breather valve due to excessively high local temperatures. Furthermore, the entry of external humid gas into the breather valve is also a significant factor leading to increased internal humidity and easy icing. Existing breather valves lack structural designs that effectively address this problem. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an oil tank breather valve with an intelligent temperature control de-icing structure. The technical solution adopted is as follows: it includes a breather valve body, characterized in that an installation box is fixedly installed on the side of the breather valve body, a rubber plate is fixedly installed at the opening of the installation box by bolts, a storage battery and a control module are fixedly installed inside the installation box, the control module is electrically connected to the storage battery, a temperature control de-icing mechanism is installed inside the breather valve body, and a dehumidification mechanism for preventing external water vapor from entering the breather valve body is installed on the side of the breather valve body;

[0005] The temperature-controlled de-icing mechanism includes a heating element, a temperature sensor, and a humidity sensor. The temperature sensor and humidity sensor are fixedly installed on the inner wall of the breathing valve body. The heating element is annular and is fixedly installed in the cavity of the side wall of the breathing valve body. The heating element, temperature sensor, and humidity sensor are electrically connected to the control module.

[0006] The dehumidification mechanism includes a waterproof and breathable membrane, a mesh frame, activated alumina, and a frame. The frame is fixedly installed on the side of the breathing valve body. The waterproof and breathable membrane is fixedly installed inside the frame. The mesh frame is fixedly installed on the top of the frame. The mesh frame is honeycomb-shaped. Activated alumina particles are fixedly connected to the hollow parts of the mesh frame. The mesh frame is located inside the air inlet and outlet on the side of the breathing valve body.

[0007] As a preferred embodiment of this invention, the heating element is a flexible electrothermal film.

[0008] As a preferred embodiment of this utility model, a rubber ring is fixedly installed on the top of the frame, and the rubber ring cooperates with the air inlet and outlet on the side of the breathing valve body.

[0009] In a preferred embodiment of this invention, the side of the arc-shaped portion of the frame is fixedly connected to one end of the support plate, and the top of the other end of the support plate is fixedly connected to the bottom of the frame-shaped portion. In another preferred embodiment of this invention, a wireless communication module is fixedly installed inside the mounting box, and the wireless communication module is electrically connected to the control module.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model monitors the environmental data inside the breathing valve in real time through temperature and humidity sensors. Combined with the intelligent judgment of the control module, it can accurately control the operation of the heating element and realize on-demand de-icing. Compared with the traditional continuous heating method, it greatly reduces energy consumption. The use of a flexible heating film as the heating element can evenly heat the inside of the breathing valve, avoid damage to the breathing valve caused by excessive local temperature, and improve the service life and safety of the breathing valve.

[0011] 2. Through the waterproof and breathable membrane and activated alumina particles, normal gas flow can be ensured while effectively blocking liquid water and adsorbing water vapor. This prevents external humid gas from increasing the humidity inside the breathing valve, reducing the possibility of icing inside the breathing valve from the source, and further improving the reliability and stability of the breathing valve in complex environments.

[0012] 3. The tight fit between the rubber ring and the air inlet / outlet on the side of the breathing valve body enhances the sealing between the dehumidification mechanism and the breathing valve body, further preventing the entry of external humid air; the support plate makes the structure of the dehumidification mechanism more stable; the wireless communication module enables remote monitoring and management functions, allowing staff to understand the working status of the breathing valve in real time without going to the site, improving management efficiency and facilitating timely detection and handling of problems.

The technical solution adopted includes a breather valve body 1, an installation box 2 fixedly installed on the side of the breather valve body 1, a rubber plate 3 fixedly installed at the opening of the installation box 2 by bolts, a battery 4 and a control module 5 fixedly installed inside the installation box 2, the control module 5 being electrically connected to the battery 4, a wireless communication module 10 fixedly installed inside the installation box 2, the wireless communication module 10 being electrically connected to the control module 5, and remote monitoring and management functions are realized through the wireless communication module 10. The staff can understand the working status of the breather valve in real time without going to the site, which improves management efficiency and facilitates timely detection and handling of problems. A temperature-controlled de-icing mechanism 6 is installed inside the breather valve body 1, and a dehumidification mechanism 7 is installed on the side of the breather valve body 1 to prevent external water vapor from entering the breather valve body 1.

[0022] The temperature-controlled de-icing mechanism 6 includes a heating element 61, a temperature sensor 62, and a humidity sensor 63. The temperature sensor 62 and humidity sensor 63 are fixedly installed on the inner wall of the breathing valve body 1. The heating element 61 is annular and is fixedly installed in the cavity of the side wall of the breathing valve body 1. The heating element 61 is a flexible electric heating film. The heating element 61, the temperature sensor 62, and the humidity sensor 63 are electrically connected to the control module 5. This utility model monitors the environmental data inside the breathing valve body 1 in real time through the temperature sensor 62 and the humidity sensor 63. Combined with the intelligent judgment of the control module 5, it can accurately control the operation of the heating element 61 and realize de-icing on demand. Compared with the traditional continuous heating method, it greatly reduces energy consumption. Using a flexible heating film as the heating element 61 can evenly heat the inside of the breathing valve body 1, avoid local overheating and damage to the breathing valve, and improve the service life and safety of the breathing valve.

[0023] The dehumidification mechanism 7 includes a waterproof and breathable membrane 71, a mesh frame 72, activated alumina 73, and a frame 74. The frame 74 is fixedly installed on the side of the breathing valve body 1. The waterproof and breathable membrane 71 is fixedly installed inside the frame 74. A rubber ring 8 is fixedly installed on the top of the frame 74. The rubber ring 8 cooperates with the air inlet and outlet on the side of the breathing valve body 1. The tight cooperation between the rubber ring 8 and the air inlet and outlet on the side of the breathing valve body 1 enhances the sealing between the dehumidification mechanism 7 and the breathing valve body 1, further preventing the entry of external humid air. The side of the arc-shaped part of the frame 74 is fixedly connected to one end of the support plate 9, and the top of the other end of the support plate 9 is connected to the frame-shaped part of the frame 74. The bottom of the frame 74 is fixedly connected, and the support plate 9 makes the structure of the dehumidification mechanism 7 more stable. The top of the frame 74 is fixedly installed with a mesh frame 72, which is honeycomb-shaped. Activated alumina 73 particles are fixedly connected in the hollow of the mesh frame 72. The mesh frame 72 is located in the air inlet and outlet on the side of the breathing valve body 1. Through the waterproof and breathable membrane 71 and the activated alumina particles 73, it can not only ensure the normal flow of gas, but also effectively block liquid water and adsorb water vapor, prevent external humid gas from increasing the humidity inside the breathing valve body 1, reduce the possibility of ice formation inside the breathing valve from the source, and further improve the reliability and stability of the breathing valve in complex environments.

[0024] The working principle of this utility model is as follows: Inside the mounting box 2 installed on the side of the breathing valve body 1, the battery 4 powers the control module 5 and the wireless communication module 10. The temperature sensor 62 and humidity sensor 63 in the temperature-controlled de-icing mechanism 6 monitor the internal temperature and humidity of the breathing valve body in real time. When the temperature is below a set threshold (e.g., below 0 degrees Celsius) and the humidity is above a critical value (above 70% RH), the control module 5 controls the flexible electric heating film heater 61, which is annularly installed in the cavity of the side wall of the breathing valve body, to be energized and heated. Based on real-time data, the power is dynamically adjusted to achieve precise de-icing. When the temperature is above 10 degrees Celsius and the humidity is above 70% RH... Heating and de-icing automatically stop when the RH level drops below 20%. In the dehumidification mechanism 7, the waterproof and breathable membrane 71 inside the frame 74 blocks liquid water, and the activated alumina 73 particles inside the honeycomb mesh frame 72 at the top adsorb water vapor. The rubber ring 8 at the top of the frame 74 cooperates with the air inlet and outlet of the breathing valve to enhance the sealing. The support plate 9 stabilizes the structure. After dehumidification, the airflow enters the breathing valve 1, further preventing ice formation inside the breathing valve 1. At the same time, the wireless communication module 10 transmits data remotely, allowing staff to monitor and manage in real time. All components work together to achieve environmental monitoring, intelligent de-icing, and moisture protection.
