INTERAPP BVO22-F不锈钢法兰球阀，INTERAPP气动球阀，INTERAPP电动球阀当操作阀门时，由于球体和聚四氟乙烯等非金属材料阀座之间摩擦，会产生静电电荷并聚积在球体行。为防止产生静电火花，特在阀门上设置防静电装置，把产生的静电导出。防火结构：采用独特结构，当发生火灾时，非金属密封面材料烧毁时，金属环利用弹簧的弹力推动阀座与球体吻合密封，从而阻止火势蔓延和介质外流。

INTERAPP BVO22-F stainless steel flange ball valve, INTERAPP pneumatic ball valve, INTERAPP electric ball valve When operating the valve, due to the ball and PTFE and other non-metallic materials between the valve seat friction, will produce electrostatic charge and accumulation in the ball line. In order to prevent the occurrence of static sparks, special anti-static device on the valve, the resulting static electricity derived. Fireproof structure: the use of a unique structure, when the fire, the non-metallic sealing surface material burned, the metal ring to use the spring to push the valve seat and the ball fit the seal, thus preventing the spread of fire and media outflow. The same time as the above-
