锻钢低温阀门不可替代的特点
  One,forged steel low temperature valve containing spare parts material:
 
  Valve body,valve seat,gate,gasket,valve cover,valve cover bolt,stem,packing,cylinder pin,bolt,packing press cover,packing press plate,nut,stem nut,lubricating pad,lock nut,hand wheel.
 
  Two,the structural characteristics of forged steel low temperature valve:
 
  Bolt wound gasket and thread welded seal type,full diameter or diameter shrinkage,seal with stable pressure hole(for gate valve,ball valve),integral seat seal,rod bracket,anti-static,self centering sleeve type pressure plate is summarized as above.
 
  Three,six requirements for the design of low temperature valve:
 
  1,the valve should be in the low temperature medium and ambient temperature should have the ability to work for a long time.
 
  2,in order to be able to use at low temperature-196,the valve is generally designed to be extended valve cover.
 
  3,the work of the valve assembly can not be lubricated at low temperature,it is necessary to take structural measures to prevent the friction parts.
 
  4,the low temperature medium does not deal with the hand wheel operation and the packing seal performance has the harmful influence.
 
  5,direct contact with the low temperature medium valve assembly should have the structure of explosion proof and fire protection.
 
  6,the valve should not be a significant source of low temperature system,this is because the inflow of heat in addition to reducing the efficiency of low heat efficiency,such as excessive inflow,but also the internal fluid rapid evaporation,resulting in abnormal boost,resulting in danger.
 
  Conclude:
 
  Forged steel valve is very suitable for low temperature pipeline in thermal power plants of various systems,control of pipe breaking medium.Applicable medium:water,steam and other non corrosive medium.Forged steel valves and other valve products than is characterized by high temperature and high pressure,the unique self seal design,the higher the pressure,the more reliable seal.Due to technical performance the product characteristics,special conditions also formed the characteristics of other products can not be replaced.
 
  一,锻钢低温阀包含备件材料:
 
  阀体,阀座,闸板,垫片,阀盖,阀盖螺栓,阀杆,填料,缸销,螺栓,填料压盖,填料压板,螺母,阀杆螺母,润滑垫,锁紧螺母,手轮。
 
  二,锻钢低温阀的结构特点:
 
  螺栓垫圈和螺纹焊接密封类型,全直径或直径收缩,具有稳定压力孔的密封(用于闸阀,球阀),整体座密封,杆支架,防静电,自定心套筒式压板。
 
  三,低温阀设计要求:
 
  1,阀门应在低温介质和环境温度下应具有长时间工作的能力。
 
  2,为了能在低温下使用-196,阀门一般设计成延伸阀盖。
 
  3,阀组件的工作不能在低温下润滑,必须采取结构措施以防止摩擦部件。
 
  4,低温介质不处理手轮操作,填料密封性能有不良影响。
 
  5,直接接触低温介质阀组件应具有防爆和防火结构。
 
  6,阀门不应该是低温系统的重要来源,这是因为流入的热量除了降低了低热效率的效率,如过量流入,而且内部流体快速蒸发,导致异常升压,导致危险。
 
  得出结论:
 
  锻造钢阀非常适合各种系统火力发电厂的低温管道,管道破碎介质的控制。适用介质:水,蒸汽等非腐蚀性介质。锻造钢阀等阀门产品比以高温高压为特点,独特的自密封设计,压力越高,密封越可靠。由于技术性能的特点,产品特性,特殊条件也形成了其他产品的特点,不能替代。
