您知道陶瓷阀门怎么维护保养了嘛?
  Ceramic valve is often used in harsh conditions working conditions,the installation process in the heavy pipe,the working conditions are extremely complicated,if there is a problem,because of its bulky,hard to pinpoint the problem,often make people at a loss what to do but also put into operation system,system,integrity,regulating quality,environmental pollution and other issues,so the rational use of ceramic valves.The maximum of its maintenance,prolong the service life,is a primary issue in the use of ceramic valves.
 
  Ceramic valves first adopted the two piece structure,in the valve structure is more reasonable,into the three type structure is now commonly used,this structure as a two seat,it also has a double sealing.At the same time in the selection of ceramic ball with sloping design of the valve,this valve can reduce fluid the impact of share.Ceramic valve means of prolonging life for you.
 
  First,the cleaning pipe to extend the life
 
  The pipeline welding slag,rust,solidification of waste products,wire,cloth etc.in the throttle,the arc guiding polishing machine parts caused by blocked or stuck valve fragments,often occur in the new operation system and put into operation after the initial repair.This is the most common faults.In this case,the discharge opening must be clean,get rid of slag material,such as the sealing surface should be ground by the injury;at the same time,open the bottom plug,to flush slag material,and pipe for flushing.Before operation,to adjust valve fully open,and then let the media flow into the normal operation after a period of time.
 
  Two,increase the opening work to extend the life
 
  In the beginning to make use of ceramic valves on the maximum aperture,such as 80%.,initial impurity pipe erosion,abrasion and other damage occurred in the valve damaged part outside,remove the pipe in the impurities,then the valve opening is adjusted to the normal opening slightly larger place.With the destruction of fluid on the spool,flow,arc polishing machine reduced opening,so continue to disrupt the gradual closure of the entire spool fully used until the spool and the sealing surface of root damage,can not be used up.
 
  Three,change the structure of arc polishing machine to improve life
 
  Ceramic control valve first uses two chip structure to the valve structure is more reasonable,into the three type structure is now commonly used,this structure as a two seat,it also has a double sealing.At the same time in the selection of ceramic ball with inclined surface transition design of the valve,this valve can reduce the impact of fluid.
 
  Four,the transfer of damage position to improve the life of the destruction of the local transfer to a secondary position,to protect the valve seat sealing surface and the cutting surface of the ceramic ball.Usually the most severe erosion,where the fastest flow of fluid is the lower part of the import,the now three piece ceramic valve structure,the core can change the ball to use.So a ball can be used for four times at the entrance,extend the life of the valve 4 times.
 
  Five,increase the diameter of life
 
  We calculated CV values,calculated the CV to choose the correct valve suitable caliber.In the case of the same flow rate,the smaller the valve diameter,the faster the fluid flow rate,medium erosion on the spool and seal the more severe.The scope of the proposed user opening can freely adjust.Increase the valve diameter,which play a role in reducing wear and tear.
 
  陶瓷阀门常用于恶劣工况条件下,在重型管道安装过程中,工作条件极为复杂,如果有问题,由于其体积大,难以准确定位的问题,往往使人们失去了还要投入运行的系统,系统,完整性,调节质量,环境污染等问题,使陶瓷阀门合理使用。其维护的最大值,延长使用寿命是使用陶瓷阀的主要问题。
 
  陶瓷阀门首先采用了两片式结构,在阀门结构更为合理,现在常用的三种型式结构,这种结构作为一个双座,它也有双重密封。同时在选择陶瓷球时采用倾斜设计的阀门,这种阀门可以减少液体的共享冲击。陶瓷阀门为您延长使用寿命。
 
  首先,清洗管延长寿命
 
  管道焊渣,铁屑,铁屑,布料等在节流阀,导弧抛光机零件造成的堵塞或卡住阀门碎片,经常发生在新的操作系统中并在初始维修后投入运行。这是最常见的故障。在这种情况下,排出口必须清洁,除去炉渣材料,如密封面应受到受伤的地面;同时打开底塞,冲洗渣料,并冲洗管道。操作前,先调节阀门全开,然后让介质流入正常工作一段时间后。
 
  二,增加开放工作延长寿命
 
  在开始使用陶瓷阀门时最大孔径,如80%以上,初始杂质管道侵蚀,磨损等损坏发生在阀门外部损坏部位,去除管道中的杂质,然后调节阀门开度到正常开口稍大的地方。随着流体在阀芯上的破坏,流动,电弧抛光机减少开口,因此继续扰乱整个阀芯的完全使用,直到阀芯和密封面的根部损坏,不能用完。
 
  三,改变圆弧抛光机的结构,提高使用寿命
 
  陶瓷控制阀首先采用两个芯片结构,阀结构更为合理,进入三型结构现在普遍采用,这种结构作为一个双座,它也有双重密封。同时在选用具有斜面过渡设计的陶瓷球阀时,该阀可以减少液体的冲击。
 
  四,转移损伤位置,提高破坏寿命,局部转移到二级位置,保护阀座密封面和陶瓷球的切割面。通常最严重的侵蚀,其中流体的最快流量是进口的较低部分,现在的三片陶瓷阀门结构,核心可以改变球使用。所以一个球可以在入口处使用四次,延长阀门的使用寿命4次。
 
  五,增加生活的直径
 
  我们计算CV值,计算CV以选择正确的阀门合适的口径。在相同流量的情况下,阀直径越小,流体流速越快,阀芯上的介质侵蚀和密封越严重。所提出的用户打开的范围可以自由调整。增加阀门直径,起到减少磨损的作用。
