UL認證熔斷閥設計是用于當環(huán)境溫度達到設定值時自動切斷液體，溶劑，酒精，有毒液體或任何其他潛在危險介質(zhì)的管道系統(tǒng)。一旦火災發(fā)生，這些閥門將自動終止液體，溶劑，酒精，有毒液體或任何其他潛在危險介質(zhì)的供應，終止或者降低火災事故所造成的危害。在發(fā)生火災時， 熔斷閥的熔斷片在達到預設值的時候自動分離，進而驅(qū)動閥門頂端的執(zhí)行器，閥門由常開變成常閉或由常閉變成常開。

熔斷閥擁有不同的溫度設置值，可根據(jù)項目實際情況，自由選擇，通常，熔斷閥的設定溫度宜大于環(huán)境溫度30℃。在易燃儲罐進出口系統(tǒng)中，是一個非常理想的選擇。另外熔斷閥在使用過程中只需在線更換斷掉的熔斷器即可重復使用， 從而降低了使用成本。

UL認證熔斷閥產(chǎn)品特點 ：
1，火災時能夠自動切斷
2，熔斷溫度為165°F （74℃）- 360°F （182℃）可選
3，材質(zhì)有碳鋼，不銹鋼，
4，閥體有球閥與蝶閥
5，連接方式：球閥/螺紋，焊接，法蘭。蝶閥/對夾，法蘭
6，應用介質(zhì)：氨，燃氣，液化氣，甲醇，油品，可燃氣體/液體
7，采用304不銹鋼零部件，確保油料輸送時的清潔，提高了防腐蝕性能。
熔斷閥是一種防止火災發(fā)生時能自行探測溫度關(guān)閉的閥門。閥門保持常開狀態(tài)，當環(huán)境溫度超過一定范圍值時，自動關(guān)閉，起到安全防火作用。

產(chǎn)品通過FM防火認證 UL安全認證

The UL-certified fusible valve is designed to automatically cut off pipeline systems for liquids, solvents, alcohols, toxic liquids or any other potentially hazardous media when the ambient temperature reaches a set value. In the event of a fire, these valves will automatically terminate the supply of liquids, solvents, alcohols, toxic liquids or any other potentially hazardous media, and terminate or reduce the hazards caused by fire accidents. In case of fire, the fuse of the fusible valve automatically separates when reaching the preset value, and then drives the actuator at the top of the valve. The valve changes from normally open to normally closed or from normally closed to normally open. Fusible valves have different temperature setting values. According to the actual situation of the project, you can freely choose. Generally, the set temperature of the fusible valve should be greater than the ambient temperature by 30 °C. It is a very ideal choice in the inlet and outlet system of flammable storage tanks. In addition, during the use of the fusible valve, it can be reused only by replacing the broken fuse online, thereby reducing the use cost. Product features of

 UL-certified fusible valve: 

1. It can be automatically cut off in case of fire. 

2. The fusing temperature is optional from 165°F (74°C) to 360°F (182°C). 

3. Materials are carbon steel and stainless steel.

 4. The valve body has ball valves and butterfly valves. 

5. Connection methods: ball valve / thread, welding, flange. Butterfly valve / wafer, flange. 

6. Applied media: ammonia, gas, liquefied gas, methanol, oil products, combustible gas/liquid. 

7. Adopting 304 stainless steel parts and components ensures the cleanliness during oil transportation and improves the anti-corrosion performance. The fusible valve is a valve that can detect the temperature and close by itself when a fire occurs. The valve remains normally open. When the ambient temperature exceeds a certain range, it will automatically close and play a role in safety and fire prevention. The product has passed FM fire certification and UL safety certification.
