一、进口电动三通内螺纹球阀产品概述

美国威盾VTON的电动三通内螺纹球阀是指由不锈钢的三通内螺纹球阀和电动执行器组成，可以用来控制分流合流，或者改变介质流动方向的控制单元。

球芯有L型有三通双口孔种，改变球芯与管道的相对角度，可以对三支管道流体实现不同的组合控制；T型孔道可起配比作用，适用于液体、气体、蒸汽等介质的配比调节与控制。电动三通内螺纹球阀采用YH型、YHQ型角行程电动执行机构，以AC220V、AC380V或DC24V电源电压作动力，接受工业自动化仪表控制系统输入的（4-20mA、或1-5VDC）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。

VTON's electric three-way internal thread ball valve refers to a control unit composed of stainless steel three-way internal thread ball valve and electric actuator, which can be used to control flow diversion and convergence, or change the direction of medium flow.

The ball core has L-shaped and three-way double hole types, and changing the relative angle between the ball core and the pipeline can achieve different combination control of the fluid in the three pipelines; The T-shaped channel can serve as a proportioning function and is suitable for adjusting and controlling the proportioning of media such as liquids, gases, and vapors. The electric three-way internal threaded ball valve adopts YH and YHQ angle stroke electric actuators, powered by AC220V, AC380V or DC24V power supply voltage, and receives (4-20mA, or 1-5VDC) current or voltage signals input from the industrial automation instrument control system to control operation and achieve proportional adjustment or two position switching control of the process medium.

二、进口电动三通内螺纹球阀特点

（1）电动三通内螺纹球阀有两座和四座密封结构，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，改变阀芯孔道与管道口的连接状态，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格的场合。

（2）两阀座密封三通球阀具有结构紧凑、外形美观、密封性能好，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。

（3）四阀座密封三通球阀具有造型美观、结构紧凑合理，它不仅可实现介质流向的切换，也可使三个通道相互连通，同时可关闭任意一个通道，使另外两个通道连通，灵活控制管路是介质的合流或分流。

（4）T型阀芯孔道可使三条正交的管道互相连通或切换，起分流或合流作用；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 electric three-way internal threaded ball valve has two and four sealing structures, and 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 hole 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 compact structure, beautiful appearance, and good sealing performance, which can achieve the switching of medium flow direction in the pipeline. It can 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 can not only switch the flow direction of the medium, but also connect 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 can connect or switch three orthogonal pipelines to each other, playing a role in diversion or 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.
