api600伞齿轮闸阀
api600闸阀特点
- 通过阀座气密性的短程或远程保护提供完全关闭。positive shutoff with visual or remote proof of seat tightness.
- 没有产品污染的绝对气密性。no product contamination absolute tightness.
- 双阀座：合成橡胶 -金属阀座加上金属-金属第二重密封。 dual seating.elastomer-to-metal seat plus metal-to-metal secondary seal.
- 防火：如果第二重合成橡胶阀座在火灾期间被损坏，则金属-金属阀座还可以保证气密性。fire safe.the metal-to-metal seat ensures tightness if the secondary elastomer seat is damaged during the fire.
- ptfe阀座镶嵌件：抗介质的腐蚀，在工作温度达到204°c时，具有很好的抗磨能力。 ptfe seat in-sertresists corrosive media, has high abrasion resistance and operates up to +400°f (204°c).
- 配置410不锈钢和密封焊接的阀座硬面。seat hardfaced with ss 410 and seal welded.
易于在线进行阀门阀座维修easy in-line valve reseating
阀座用410不锈钢进行硬面，通过焊接装配延长使用寿命。将楔板从阀体上拆卸后，磨损的软阀座镶嵌件就很容易更换了。在更换阀座镶嵌件之前，关闭流体，减轻压力。 seats are hardfaced with ss 410 and welded-in for lifetime service. a worn soft seat in-sert can easily be replaced after removal of wedge from the body. shut off flow and relieve pressure before replacing the seat in-sert.
