24/7 anti-freezing breather valve for oil tanks
Thread Content
To avoid breathing losses in oil tanks, anti-freezing breath valves are now commonly used. In winter, when the oil breathes out, it can freeze on the breath valve, which may lead to poor breathing function. I would like to ask experienced sailors how to address this issue It would be better if there are maintenance procedures? My email address is lhyln78@126.com, thank you

http://www.shshunfa.com/vsites/es00020549/uploadfile/image001.jpg The casing is made of high-quality aluminum alloy, offering light weight and excellent corrosion resistance. http://www.shshunfa.com/vsites/es00020549/uploadfile/image002.jpg The breathing valve is constructed from high-quality aluminum alloy combined with engineering plastic (tetrafluoroethylene), providing corrosion resistance and good performance in varying temperature conditions, allowing it to function properly around the clock. http://www.shshunfa.com/vsites/es00020549/uploadfile/image004.jpg The ripple flame-retardant layer is made of stainless steel, offering excellent flame-retardant properties as well as good corrosion resistance. Application range: The all-weather explosion-proof flame arrestor breather valve is suitable for storage tanks containing Class A oils with a flash point below 28°C and Class B oils with a flash point below 60°C, such as gasoline, benzene, toluene, kerosene, light diesel, crude oil, and other similar oils. Features and performance: The casing is made of aluminum alloy, offering light weight and strong corrosion resistance. The flame arrestor layer is easy to install and inspect, ensuring safety. The flame-retardant performance fully meets the requirements of GB5908. The aeration performance fully meets the requirements of SY7511. Hydraulic test passed. Maintenance: To ensure safe use, the flame arrestor layer should be cleaned every 3 months to keep all holes in it unobstructed and prevent blockages. 2. Check every 3 months whether the positive and negative pressure valve discs move smoothly, and that there is no damage to the contact sealing surfaces of the guide rods and valve discs. 3. During reinstallation, it is necessary to ensure that all joint surfaces fit tightly together and that the valve disc moves up and down smoothly. 4. The shock-absorbing materials between the discs should be removed before the new valve is put into use. Selection of diameter for all-weather explosion-proof flame-arresting breather valves: The diameter of such valves is determined based on the maximum flow rate of oil in and out of the tank. According to the flow rate (in m³/h): <50, 51–100, 101–150, 151–250, 251–300, >300. The diameter and number of explosion-proof breather valves are as follows: DN×n = 50×1, 100×1, 1100×1, 1150×1, 1200×1, 1250×1, 1200×2.
