一、进口不锈钢电动三通球阀概述

美国威盾VTON进口内螺纹电动三通球阀采用不锈钢的三通球阀，结合回转式角行程电动执行机构，以AC220V、380V、DC24V电源电压作动力，三通球阀接受工业自动化仪表控制系统输入（4-20mA）电流信号或电压信号，即可控制运转，实现对工艺介质的比例调节或二位切换控制。进口电动三通球阀依先进技术而开发的新型三通切换型调节阀。标准球芯有L型三通双口孔种，改变球芯与管道相对角度，可以对三支管道流体实现不同的组合控制；T型电动三通球阀孔道可起配比作用，适用于液体、气体、蒸汽等介质的配比调节与控制。  

The VTON internal threaded electric three-way ball valve adopts a stainless steel three-way ball valve, combined with a rotary angle stroke electric actuator, powered by AC220V, 380V, DC24V power supply voltage. The three-way ball valve receives an input (4-20mA) current signal or voltage signal from the industrial automation instrument control system to control operation and achieve proportional adjustment or two position switching control of the process medium. A new type of three-way switching control valve developed based on advanced technology for imported electric three-way ball valves. The standard ball core has L-shaped three-way double port holes, and changing the relative angle between the ball core and the pipeline can achieve different combinations of fluid control for the three pipelines; The T-shaped electric three-way ball valve orifice can play a proportioning role and is suitable for adjusting and controlling the proportioning of liquids, gases, steam and other media.

二、进口电动三通球阀产品特点

1.三通球阀有两阀座和四座密封结构，阀芯孔道有L型和T型两种结构形式，采用控制阀芯旋转角度，改变阀芯与管道口连接状态，可实现对三条支管不同的组合控制。三通球阀流通能力大，可控制气体、液体、蒸汽，更适用于控制高粘度，纤维颗粒状的流体。也适用于密封要求较严合的场合。

2.两阀座密封三通球阀具有造型美观、结构紧凑合理，它不仅可实现介质流向的切换，也可使相互垂直的两个通道连接或关闭。

3.四阀座密封三通球阀具有造型美观、结构紧凑合理，它不仅实现介质流向的切换，也要使三个通道相互联通，同时可关闭任意一个通道，使另个两个通道连接，灵活控制管路是介质的合流或分流

4.三通球阀T型阀芯孔道可使三条正交的管道互相连接或切换，起分流和合流作用；L型孔道连接相互正交的两管道。使另一条孔道切断，起改变介质流向作用。  

1.The three-way ball valve has two valve seats and four sealing structures. The valve core hole has two structural forms, L-shaped and T-shaped. By controlling the rotation angle of the valve core and changing the connection status between the valve core and the pipeline mouth, it can achieve different combination control of the three branch pipes. The three-way ball valve has a large flow capacity and can control gases, liquids, and vapors, making it more suitable for controlling high viscosity, fibrous and granular fluids. It is also suitable for occasions with strict sealing requirements.

2.The two seat sealed three-way ball valve has a beautiful appearance and a compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect or close two perpendicular channels.

3.The four seat sealed three-way ball valve has a beautiful appearance and a compact and reasonable structure. It not only switches the flow direction of the medium, but also connects the three channels. At the same time, any channel can be closed to connect the other two channels, and the pipeline can be flexibly controlled to merge or separate the medium

4.The T-shaped valve core hole of the three-way ball valve can connect or switch three orthogonal pipelines to each other, playing a role in diversion and convergence; L-shaped channels connect two pipes that are orthogonal to each other. Cut off another channel to change the flow direction of the medium.

三、进口不锈钢电动三通球阀流向原理

L型三通球阀采用两阀座密封结构，外形美观、密封性能好，它能实现对管道中介质流向的切换，也能使相互垂直的两个通道连通或关闭。

T型三通球阀适用于介质的分流、合流或流向切换，可以使三个通道互相连通或使其中两个通道连通。 

The L-shaped three-way ball valve adopts a two seat sealing structure, which has a beautiful appearance and good sealing performance. It can switch the flow direction of the medium in the pipeline and also connect or close two perpendicular channels.

The T-shaped three-way ball valve is suitable for the diversion, merging, or flow direction switching of media, which can connect three channels to each other or connect two of them.
