UL认证熔断阀

UL认证熔断阀设计是用于当环境温度达到设定值时自动切断液体，溶剂，酒精，有毒液体或任何其他潜在危险介质的管道系统。一旦火灾发生，这些阀门将自动终止液体，溶剂，酒精，有毒液体或任何其他潜在危险介质的供应，终止或者降低火灾事故所造成的危害。在发生火灾时， 熔断阀的熔断片在达到预设值的时候自动分离，进而驱动阀门顶端的执行器，阀门由常开变成常闭或由常闭变成常开。

熔断阀拥有不同的温度设置值，可根据项目实际情况，自由选择，通常，熔断阀的设定温度宜大于环境温度30℃。在易燃储罐进出口系统中，是一个非常理想的选择。另外熔断阀在使用过程中只需在线更换断掉的熔断器即可重复使用， 从而降低了使用成本。

UL认证熔断阀产品特点 ：
1，火灾时能够自动切断
2，熔断温度为165°F （74℃）- 360°F （182℃）可选
3，材质有碳钢，不锈钢，
4，阀体有球阀与蝶阀
5，连接方式：球阀/螺纹，焊接，法兰。蝶阀/对夹，法兰
6，应用介质：氨，燃气，液化气，甲醇，油品，可燃气体/液体
7，采用304不锈钢零部件，确保油料输送时的清洁，提高了防腐蚀性能。
熔断阀是一种防止火灾发生时能自行探测温度关闭的阀门。阀门保持常开状态，当环境温度超过一定范围值时，自动关闭，起到安全防火作用。

产品通过FM防火认证 UL安全认证

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.
