  下面讲解了焊接截止阀的维护

  焊接截止阀应该如何维护?

  一、焊接截止阀注脂时,注脂量不能忽略,注脂加油后,运维管理人员需要选择一个阀门和注脂加入生活方式,然后进行注脂,有两种工况:一方面是注脂量少且注脂不足,密封面因缺少润滑剂而加速,另一方面,过多的脂肪注射导致资源浪费,企业没有根据国内阀门产品的主要类别计算不同截止阀密封系统的容量数据,可以根据截止阀的尺寸和类别计算密封环境容量,然后合理注入适量的润滑脂。

  二、气门上油时,压力问题往往被忽略,在注脂操作过程中,注脂压力会周期性变化,压力低、密封泄漏或失效、压力高、注脂口堵塞、密封内油脂硬化或密封环与阀球和阀板扣合,通常,当注射压力过低时,注射的润滑脂会流入阀腔底部,通常是在小型闸阀中,一方面检查吸 脂喷嘴;如果吸 脂嘴堵塞,查明情况,更换;另一方面,如果润滑脂变硬,则需要使用清洗液,反复软化失效的密封润滑脂,并注入新的润滑脂进行更换,此外,密封类型和密封材料也影响脂肪注射压力,不同的密封形式有不同的注脂压力,一般来说,硬密封的压力高于软密封,球阀一般处于开启状态,特殊情况下关闭维修,其他阀门不能被视为打开位置,维护期间,闸阀关闭,以确保润滑脂沿着密封圈填充密封槽,如果打开密封,密封脂会直接落入流道或阀腔,造成浪费。

  焊接切断阀运行时,各种阀门组件应处于良好状态,法兰和支架上的螺栓必不可少,螺纹应完好,无松动,手轮上的紧固螺母如有松动应及时拧紧,以免磨损接头或丢失手轮和铭牌,如果截止阀手轮丢失,不允许更换扳手,应及时补齐,填料压盖不允许偏斜或没有预紧间隙,在易受雨、雪、灰尘、沙子和其他污染的环境中,切断阀门和阀杆,并安装防护罩,截止阀上的压力表应齐全、准确、清晰,密封、盖和气动附件应完整,在阀门操作过程中,不要敲打、支撑或支撑重物,尤其是非金属和铸铁阀门,而且阀门维修时禁止焊接油脂,阀门投产后要进行专业维修,对于阀门的维护,在生产运行中起着至关重要的作用,正确有序的维护将保护阀门,使其正常运行,延长其使用寿命,阀门维护看似简单,实则不然,工作的某些方面经常被忽视。

  今天就讲解到这里了,感谢大家的收看,让我们下期再见。


 

What are the uses of pressure reducing valves?

The development prospect of the pressure reducing valve industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers, in order to let you know more, next we will tell about the use of the pressure reducing valve, and hope to help more people.
