Model: Q, Q, QH, Q, Q, Q, QH, Q The electric three-way ball valve adopts a rotary angle-stroke electric actuator, powered by or D power supply voltage, and accepts input from the industrial automation instrument control system (m) The current signal or voltage signal can be used to control the operation and realize proportional adjustment or two-position switching control of the process medium. The three-way ball valve is a new three-way switching control valve developed by integrating advanced domestic and foreign technologies.
Electric three-way ball valve standard ball core
Type three-way double-port hole type, changing the relative angle between the ball core and the pipe can achieve different combinations of control of the fluids in the three pipes
The type hole can be It plays a proportioning role and is suitable for proportioning adjustment and control of liquid, gas, steam and other media.
Technical parameters of electric three-way ball valve
Three-way ball valves have two-seat and four-seat sealing structures. The valve core hole has two structural forms: type and type. The rotation angle of the valve core is controlled to change the relationship between the valve core hole and the valve core. The connection status of the pipe mouth can realize different combination control of the three branch pipes. The three-way ball valve has a large flow capacity and can control gas, liquid, and steam. It is more suitable for controlling high-viscosity, fibrous and granular fluids. It is also suitable for occasions with strict sealing requirements.
.Two-seat sealed three-way ball valve has a compact structure, beautiful appearance and good sealing performance. It can switch the flow direction of the medium in the pipeline. It can also connect or close two channels that are perpendicular to each other.
.The four-seat sealed three-way ball valve has beautiful appearance, compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect the three channels to each other. At the same time, any one channel can be closed to make the other two channels Connected, flexible control pipelines are the confluence or divergence of media (such as flow direction diagram B).
The .-type valve core hole can connect or switch three orthogonal pipelines with each other, and the type-type pore channels that have the function of diverging or converging are connected to each other in a positive manner. Two channels of delivery. Cut off another hole to change the flow direction of the medium.
