  • 防火阀的材料要用镀锌板的原因
  • 本站编辑:杭州龙8登陆平台有限公司发布日期:2019-08-09 12:55 浏览次数:

防火阀是一种在发生火灾时作用非常大的消防设施,可以起到控制火势的作用,当火灾发生时,火焰入侵风道,高温使阀门上的易熔合金熔解,或使记忆合金产生形变使阀门自动关闭,在一定时间内能满足耐火稳定性和耐火完整性要求,起隔烟阻火作用。


Fire-proof valve is a very important fire-fighting facility in the event of fire, which can play a role in controlling the fire. When fire occurs, the flame invades the air duct, the high temperature melts the fusible alloy on the valve, or makes the memory alloy deform to make the valve shut down automatically, so as to meet the fire-resistant stability and fire-resistant finish in a certain period of time. Integrity requirements, play a smoke-proof and fire-retardant role.

很多防火阀会选用镀锌板作为材料,因为镀锌板就是表面镀锌的钢板,由于表面镀锌,所以有着非常好的防腐作用。其次镀锌钢板一般都会选用优质钢板作为材料,所以耐高温性能强,而且焊接性能也非常好,所以镀锌板防火阀也是非常优质的一种防火阀设备。


Many fire valves will choose galvanized sheet as the material, because galvanized sheet is the surface of galvanized steel plate, because the surface of galvanized, so it has a very good anti-corrosion effect. Secondly, galvanized steel plate will generally choose high-quality steel plate as the material, so the high-temperature resistance is strong, and the welding performance is very good, so galvanized plate fire valve is also a very high-quality fire valve equipment.
