Pneumatic Three-way Ball Valve
详情介绍
product description
One,use and characteristics of pneumatic tee ball valve
1. Compact structure, quick opening and closing, smooth flow path and small fluid resistance.
2, good sealing performance: the use of four side seat material ptfe elastic deformation to achieve leak-free sealing.
3, a multi-purpose valve: any port can be used as an entrance without leakage, tee can be made into an l-shaped port, also can be made into a t-shaped port.
4, easy maintenance: after the system pressure relief, without removing the whole valve body can be checked and maintained.
5, widely used in water supply, petrochemical, metallurgy, mining, light textile, energy, paper, food, steel and other pipeline systems to switch the flow direction of the medium and the medium of the diversion or mixed fluid.
Two, pneumatic tee ball valve medium flow principle
Three-way ball valve is divided into l-type and t-type, medium flow direction is shown in the following figure. L-type three-way ball valve is suitable for the medium flow switch, can make the two channels connected perpendicular: T tap, confluence of three-way ball valve is suitable for the medium or flow switch, T channel can make the three channels connected to each other or make two of them connected, the 3-way ball valve generally adopt two seat structure, can also according to user requirements adopted four seat structure.
