QT3M仪表三通球阀特点：

  (1）流体阻力小，全通径的球阀基本没有流阻。
 （2）结构简单、体积小、重量轻。
 （3）紧密稳定。它有两个密封面，而且目前球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。在真空系统中也已广泛使用。
  (4）操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
 （5）维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
 （6）在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
 （7）适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
 （8）由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。

 Product Overview of Instrument Three - way Ball Valve

 The instrument three - way ball valve is a kind of valve used to control the flow direction of fluid switch the flow channel, which is widely used in the industrial field. The product overview is as follows:

 The instrument three - Structural Features: It usually adopts an integrated structure with a four - faced seat sealing type. The valve body can be made by precision casting forging. The valve core is generally O - shaped, common materials include stainless steel, etc. The sealing materials of the valve seat include polytetrafluoroethylene (PTFE), polyphenylene (PPL), etc.

The instrument three - Working Principle: The opening closing of the valve the control of fluid flow direction are realized by rotating the ball. The ball rotates 90° around the center line of the valve body to complete full - open full - close. The L - type flow channel can connect two orthogonal pipelines to realize the flow direction switching of two - in - one - out. The T - type flow channel can make three orthogonal pipelines communicate with each other cut off the third channel, playing the role of shunting converging.

The instrument three - Performance Advantages: It has the characteristics of small fluid resistance, excellent sealing performance, convenient efficient operation. It can adapt to various working conditions such as high temperature, high pressure corrosive media, can achieve bidirectional sealing. Moreover, it is easy to maintain, the service life can be extended only by replacing the sealing parts.

The instrument three - Application Fields: It is widely used in petroleum, chemical, pharmaceutical, food, HVAC other industries. It can be used in scenarios such as switching the flow direction of media in oil gas transmission pipelines, multi - channel switching of reactor feed systems, raw material mixing control of blending tanks, balancing the flow of branch circuits in cold hot water systems.
