Description of the classification and functional characteristics of the three-way ball valve

The working principle of the ball valve: inside the ball valve is a steel ball with holes, the surface is very smooth, there are PTFE seals on both sides, the contact part with the ball is a circular arc surface, which is produced by the bolts or the pressing of the valve body. For sealing, a straight groove is formed at the top of the ball to transmit the torque of the handle. When the valve is opened, the hole on the ball is parallel to the axis line of the valve to form a passage; when the valve is closed, the ball is rotated by 90° through the handle to block the passage. The switch has two types: manual mode and pneumatic mode.
The three-way ball valve is divided into L-type and T-type, and the L-type three-way ball valve is suitable for the switching of the medium flow direction, and can connect two channels perpendicular to each other: the T-type three-way ball valve is suitable for the shunting, confluence or flow direction switching of the medium, T type The tunnel can connect three channels to each other or connect two of them. The three-way ball valve generally adopts two valve seat structures, and can also adopt a four-valve structure according to user requirements.
Electric three-way ball valve
Structural features:
1. Compact structure, rapid opening and closing, smooth flow path and low fluid resistance.
2, good sealing performance: the use of four-sided valve seat material PTFE elastic deformation to achieve a leak-free seal.
3, a multi-purpose valve: any port can be used as an inlet without leakage, the three-way can be made into an L-shaped port, or can be made into a T-shaped port.
4. Convenient maintenance: After the system is relieved of pressure, it can be inspected and repaired without removing the entire valve body.
5. It is generally applicable to the switching of medium flow direction and the diversion or mixing of medium in water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other pipeline systems.
Stainless steel three-way ball valve
Structural features:
1. The valve has simple structure, small volume, light weight, small flow resistance and good energy saving effect. When the medium flows through the valve, it is equivalent to flowing through a straight through pipe, and the fluid resistance is the smallest.
2. The direction of the fluid entering and leaving the valve can be arbitrarily selected and has a two-way effect.
3, valve pipe fittings are: internal thread, flange, butt welding, plug welding, quick loading, etc.! It is installed with horizontal pipes and vertical pipes.
4, easy to operate, the switch is fast, the handle operation only needs to turn 90 degrees to achieve the switch. Pneumatic, electric can be arbitrarily transferred.
5, anti-leakage effect is excellent, with a switch life can be 5-10 times higher than other equipment.
Main parts Material description: Valve body: Cast stainless steel casting; Handle: Stainless steel; Seal: Polytetrafluoroethylene and high temperature resistant seal.
Flange connection three-way ball valve
Structural features: three-way ball valve can be L-shaped and T-shaped, L-shaped (Q44F) three-way ball valve for medium flow direction switching, can connect two channels perpendicular to each other; T-shaped (Q45F) three-way ball valve for medium Split, merge, and flow direction switching. The T-shaped tee allows three channels to communicate with each other or two of them to communicate. The three-way ball valve generally adopts a two-valve structure, and can also adopt a four-valve structure according to user requirements.
Internal thread three-way ball valve
Application principle features:
The internal thread three-way ball valve is made of stainless steel as a whole, and the valve body is made of PTFE. The sealing performance is good. Suitable for mediums such as water, oil, gas and certain corrosive liquids with a pressure of 2.5 MPa. The internal thread three-way ball valve is divided into L type and T type. The L-type pneumatic three-way ball valve is suitable for switching the flow direction of the medium, and can connect two channels perpendicular to each other. The T-type pneumatic three-way ball valve is suitable for the diversion, confluence or flow direction switching of the medium. The T-shaped channel can make the three channels communicate with each other or connect two of them. The internal thread three-way ball valve generally adopts two valve seat structures. The four-valve structure is adopted according to user requirements.
