  Flange fixed ball valve product introduction:
 
  The Q347 type fixed ball valve is a new generation of high-performance ball valve,suitable for long-distance pipelines and general industrial pipeline,its strength,safety,resistance to harsh environments such as the special consideration in the design,suitable for all kinds of corrosive and non corrosive media.It compared with the floating ball work force,valve the fluid pressure generated in the ball all transferred to the bearing,not to move the ball to the seat,the seat would not put too much pressure,so fixed valve torque is small,the valve seat sealing small deformation,stable performance,long service life,suitable for high pressure and large caliber occasions.Advanced spring pre seat components.Self tight characteristic,and the upstream seal.Each valve has two valve seats,each direction can be sealed,so the installation does not flow restrictions.
 
  Working principle of flange fixed ball valve:
 
  Fixed ball valve is fixed,is composed of two sections and the sphere is connected to a fixed axis supporting together.When closed,under pressure in the medium,the sphere will not produce displacement,usually linked with the ball on the lower shaft with rolling bearing or sliding bearing.In order to reduce the friction shaft hoist when reduce operating torque.The fixed ball valve suitable for large-diameter ball valve.Q47 fixed ball valve seal.The two,stem fixed.When the fluid pressure not to move the ball to the seat,the seat would not put too much pressure and deformation.The stem part is provided with self lubricating bearings,reducing friction,small torque switch two,seats are spring set preload.Seal with PTFE inserts into the solid steel,steel ring is arranged at the rear part of the spring,ensure the seat close to the ball.When the valve in the cavity pressure abnormal increase over the top tight spring force,after the seat Withdrawal from the ball,to achieve automatic pressure relief effect,pressure after the valve seat automatic reset.The structure of the advanced nature of the fixed ball valve sealing performance and stable operation,long service life,very suitable for long transmission pipeline and general pipeline.
 
  Flange fixed ball valve product features:
 
  1,the use of fixed ball design,the relative movement of the parts are using friction coefficient of minimal self lubrication material,and thus the operation of small torque,in addition to seal the long-term sealing grease,making the operation more flexible.
 
  2,the valve using a high platform structure,ISO5211 connection standard,can make the installation of electrical/pneumatic actuator more specialized.
 
  3,the full size or reducing design,small flow resistance.
 
  4,metal hard seal O type fixed ball valve using two-way metal movable sealing structure,with automatic compensation and self cleaning function,sealing performance is superior.
 
  5,the use of fixed ball design,and increase the preload spring,so that the ball valve with automatic pressure relief function.
 
  6,each ball valve has two movable seal seat,two directions can be sealed,so the installation does not need to consider the flow of media.
 
  7,with fire anti-static structure,the conductive spring is arranged between the valve rod and the valve body and valve and ball,avoid electrostatic ignition ignite flammable media.To ensure the safety of the system.
 
  8,fireproof structure double protection,in case of a fire and the sealing ring is damaged,the ball valve can form various sealing parts of hard metal to metal seal structure.
 
  9,automatic pressure relief structure,when the liquid medium is stuck in the valve chamber and the gasification temperature rise due to increased,the abnormal pressure in the chamber,the cavity in the medium can rely on its own force and the automatic pressure relief valve seat,thus ensuring safety valve.
 
  10,optional pneumatic,electric,hydraulic,and pneumatic control type,electric control type.
 
  法兰固 定式球阀产品介绍:
 
  Q347型固定 式球阀是新一代高性能球阀,适用于 长距离管道和一般工业管道,其强度,安全性,耐恶劣 环境等特殊考虑的设计,适用于 各种的腐蚀性和非腐蚀性介质。它与浮球工作力相比,阀门所 产生的流体压力全部传递到轴承,不会将 球体移动到座位,座椅不 会施加过大的压力,因此固 定阀门的扭矩小,阀门座密封变形小,性能稳定,使用寿命长,适用于 高压和大口径场合。高级弹簧预座组件。自密特性,和上游密封。每个阀有两个阀座,每个方向可以密封,因此安 装不受流量限制。
 
  法兰固 定球阀的工作原理:
 
  固定式球阀是固定的,由两部分组成,球体与 固定轴连接在一起。当关闭时,在介质中的压力下,球体将不会产生位移,通常与 下轴上的滚珠与滚动轴承或滑动轴承连接。为了减 少摩擦轴提升机降低工作扭矩。固定球 阀适用于大直径球阀.Q47固定球阀密封。二,茎固定。当流体 压力不使球移动到座椅时,座椅不 会施加过大的压力和变形。轴杆部 分设有自润滑轴承,减少摩擦,小扭矩开关二,阀座为弹簧预紧。带有PTFE插件的 密封件放入实心钢中,弹簧的后部设置钢环,确保靠近球的座位。当阀门 在腔体内压力异常升高超过上紧力弹簧力时,座圈从球体抽出后,实现自动减压效果,阀座后自动复位压力。结构先 进的固定球阀密封性能稳定,使用寿命长,非常适 合长输管道和一般管道。
 
  法兰固 定式球阀产品特点:
 
  1,采用固定球设计,部件的 相对运动采用摩擦系数最小的自润滑材料,因此操作小扭矩,除了密 封长期密封润滑脂,使操作更加灵活。
 
  2,阀门采用高平台结构,ISO5211连接标准,可使电气/气动执 行器的安装更专业化。
 
  3,全尺寸或减小设计,流动阻力小。
 
  4,金属硬密封O型固定 球阀采用双向金属可移动密封结构,具有自 动补偿和自清洁功能,密封性能优越。
 
  5,采用固定球设计,增加预压弹簧,使球阀 具有自动卸压功能。
 
  6,每个球 阀有两个可移动密封座,两个方向可密封,因此安 装时不需要考虑介质的流动。
 
  7,具有防火防静电结构,导电弹 簧设置在阀杆与阀体和阀与球之间,避免静 电点火点燃易燃介质。以确保系统的安全。
 
  8,防火结构双重保护,万一发生火灾,密封圈损坏,球阀可 以形成各种密封件的硬金属与金属密封结构。
 
  9,自动卸压结构,当液体 介质卡在阀腔内,气化温 度由于升高而上升时,腔内的异常压力,介质中 的腔可依靠自身的力量和自动泄压阀座,从而确保安全阀。
 
  10,可选气动,电动,液压,气动控制型,电控型。
