  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.
 
  法蘭固定式球閥產品介紹:
 
  Q347型固定式球閥是新一代高性能球閥,適用于長距離管道和一般工業管道,其強度,安全性,耐惡劣環境等特殊考慮的設計,適用于各種的腐蝕性和非腐蝕性介質。它與浮球工作力相比,閥門所產生的流體壓力全部傳遞到軸承,不會將球體移動到座位,座椅不會施加過大的壓力,因此固定閥門的扭矩小,閥門座密封變形小,性能穩定,使用壽命長,適用于高壓和大口徑場合。高級彈簧預座組件。自密特性,和上游密封。每個閥有兩個閥座,每個方向可以密封,因此安裝不受流量限制。
 
  法蘭固定球閥的工作原理:
 
  固定式球閥是固定的,由兩部分組成,球體與固定軸連接在一起。當關閉時,在介質中的壓力下,球體將不會產生位移,通常與下軸上的滾珠與滾動軸承或滑動軸承連接。為了減少摩擦軸提升機降低工作扭矩。固定球閥適用于大直徑球閥.Q47固定球閥密封。二,莖固定。當流體壓力不使球移動到座椅時,座椅不會施加過大的壓力和變形。軸桿部分設有自潤滑軸承,減少摩擦,小扭矩開關二,閥座為彈簧預緊。帶有PTFE插件的密封件放入實心鋼中,彈簧的后部設置鋼環,確保靠近球的座位。當閥門在腔體內壓力異常升高超過上緊力彈簧力時,座圈從球體抽出后,實現自動減壓效果,閥座后自動復位壓力。結構先進的固定球閥密封性能穩定,使用壽命長,非常適合長輸管道和一般管道。
 
  法蘭固定式球閥產品特點:
 
  1,采用固定球設計,部件的相對運動采用摩擦系數最小的自潤滑材料,因此操作小扭矩,除了密封長期密封潤滑脂,使操作更加靈活。
 
  2,閥門采用高平臺結構,ISO5211連接標準,可使電氣/氣動執行器的安裝更專業化。
 
  3,全尺寸或減小設計,流動阻力小。
 
  4,金屬硬密封O型固定球閥采用雙向金屬可移動密封結構,具有自動補償和自清潔功能,密封性能優越。
 
  5,采用固定球設計,增加預壓彈簧,使球閥具有自動卸壓功能。
 
  6,每個球閥有兩個可移動密封座,兩個方向可密封,因此安裝時不需要考慮介質的流動。
 
  7,具有防火防靜電結構,導電彈簧設置在閥桿與閥體和閥與球之間,避免靜電點火點燃易燃介質。以確保系統的安全。
 
  8,防火結構雙重保護,萬一發生火災,密封圈損壞,球閥可以形成各種密封件的硬金屬與金屬密封結構。
 
  9,自動卸壓結構,當液體介質卡在閥腔內,氣化溫度由于升高而上升時,腔內的異常壓力,介質中的腔可依靠自身的力量和自動泄壓閥座,從而確保安全閥。
 
  10,可選氣動,電動,液壓,氣動控制型,電控型。
