Use and characteristics of pneumatic three-way ball valve
1, compact structure, fast opening and closing, smooth flow path, low fluid resistance.
2, good sealing performance: the use of four-sided seat material polytetrafluoroethylene elastic deformation to achieve leak-free sealing.
3, a multi-purpose valve: any port can be used as an entrance without leakage, three can be made into L-shaped port, can also be made into T-shaped port.
4, easy maintenance: After the system pressure relief, without removing the entire valve body can be inspected and repaired.
5, widely used in water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other pipeline systems to switch the flow of the medium and the diversion of the medium or mixed fluid.
Two, pneumatic three-way ball valve medium flow principle
The pneumatic three-way ball valve is divided into L-type and T-type, and the flow direction of the medium is shown in the figure below. L-type three-way ball valve is suitable for switching the flow direction of the medium, which can make the two vertical channels connected: T-type three-way ball valve is suitable for the diversion, confluence or flow direction switch of the medium, T-type hole can make three channels connected or two of the channels connected, three-way ball valve generally uses two seat structure, can also use four seat structure according to user requirements.
Three, pneumatic three-way ball valve implementation standards
I Design and manufacture: GB/T12237-1989; APl608.
2. Inspection and test: GB/T13927-1992; APl 598.
3 flange connection: JB/T79] 1-2-1994; ASME/ANSI B165.
