The electric vacuum ball valve is a moderate total flow suitable for opening or closing the pipeline in the ultrafiltration device. The valve adopts rotating electric and electronic devices to regulate the valve driving equipment. The electric high vacuum ball valve can be opened, closed or operated in the middle according to the external switching power conversion (controlled by manual marking power switch or computer system) or the external input data signal.. Electric high vacuum ball valve is welded and sealed by curved surface, so it can be used in vacuum pump and low voltage. And it can be assembled anywhere.

一，電動(dòng)高真空球閥的特性：

1、 Characteristics of electric high vacuum ball valve:

（1）液體阻礙小，全徑球閥大部分沒有流動(dòng)性摩擦阻力。

(1) The liquid resistance is small, and most of the full diameter ball valves have no fluidity friction resistance.

（2）電動(dòng)高真空球閥構(gòu)造簡易，體型小，重量較輕。

(2) The electric high vacuum ball valve has simple structure, small size and light weight.

（3）緊密靠譜。它有兩個(gè)密封面，現(xiàn)階段電動(dòng)高真空球閥的密封面原材料普遍適用于各種各樣塑膠，密封特性好，可以完成密封。電動(dòng)高真空球閥也已普遍用以超濾裝置。

(3) Close and reliable. It has two sealing surfaces. At present, the raw materials of the sealing surface of the electric high vacuum ball valve are generally suitable for all kinds of plastics. It has good sealing characteristics and can complete the sealing. Electric high vacuum ball valves have also been widely used in ultrafiltration devices.

（4）使用方便，開閉便捷。電動(dòng)高真空球閥從開啟到關(guān)完轉(zhuǎn)動(dòng)90°。電動(dòng)高真空球閥有利于遠(yuǎn)程操作。

(4) Easy to use, convenient to open and close. The electric high vacuum ball valve rotates 90 ° from opening to closing. Electric high vacuum ball valve is conducive to remote operation.

（5）維護(hù)保養(yǎng)便捷，球閥構(gòu)造簡易，密封圈一般合理。拆裝和拆換便捷。

(5) The maintenance is convenient, the ball valve structure is simple, and the sealing ring is generally reasonable. Convenient disassembly and replacement.

（6）當(dāng)開全或關(guān)完時(shí)，電動(dòng)高真空球閥和閥球的密封面與介質(zhì)防護(hù)。當(dāng)介質(zhì)根據(jù)時(shí)，它不容易造成閘閥密封表面的浸蝕。

(6) When fully opened or closed, the sealing surface and medium protection of electric high vacuum ball valve and valve ball. When the medium is in accordance with the requirements, it is not easy to cause the erosion of the sealing surface of the gate valve.

（7）電動(dòng)高真空球閥適用自小到幾毫米到多少米，從高真空泵到髙壓的廣泛運(yùn)用。

(7) Electric high vacuum ball valve is applicable to a wide range of applications from small to several millimeters to meters, from high vacuum pump to high pressure.

（8）因?yàn)榍蜷y在開啟和退出期內(nèi)具備擦洗特性，因而電動(dòng)高真空球閥可用以具備溶解性總固體顆粒物的介質(zhì)中。

(8) Because the ball valve has scrubbing characteristics during the opening and exit periods, the electric high vacuum ball valve can be used in the medium with soluble total solid particles.

二，電動(dòng)高真空球閥的原理：

2、 Principle of electric high vacuum ball valve:

電動(dòng)高真空球閥具備轉(zhuǎn)動(dòng)90度的功效，塞體為圓球，而且具備環(huán)形埋孔或越過其線的安全通道。球閥適用于管路中激光切割，分派和更改介質(zhì)的流動(dòng)性方位。電動(dòng)高真空球閥只需轉(zhuǎn)動(dòng)90度就可以密切關(guān)掉扭距。球閥合適作為轉(zhuǎn)換閥和截止閥門，但近期的發(fā)展趨勢設(shè)計(jì)方案了球閥以給予節(jié)流閥和操縱總流量，比如V型球閥。

The electric high vacuum ball valve has the effect of rotating 90 degrees. The plug body is a round ball, and it has a ring-shaped buried hole or a safe passage across the center line. The ball valve is suitable for laser cutting, distributing and changing the flow direction of the medium in the pipeline. The electric high vacuum ball valve only needs to rotate 90 degrees to close the torque. Ball valve is suitable as change-over valve and stop valve, but recent development trend designs ball valve to give throttle valve and control total flow, such as V-shaped ball valve.

電動(dòng)高真空球閥的主要特點(diǎn)是結(jié)構(gòu)緊湊，密封靠譜，構(gòu)造簡易，維護(hù)保養(yǎng)便捷。密封表面和球型表面通常是封閉式的，不容易被介質(zhì)腐蝕，便于使用和維修，可用強(qiáng)電解質(zhì)，有機(jī)溶劑，酸和燃?xì)?。如一般工作中介質(zhì)，電動(dòng)高真空球閥，也適用工作中情況下的介質(zhì)，如o2，雙氧水，甲烷氣體和丁二烯等，廣泛運(yùn)用于各個(gè)領(lǐng)域。球閥體可以是一體的或組成的。

The main characteristics of electric high vacuum ball valve are compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are usually closed, which are not easy to be corroded by the medium and easy to use and maintain. Strong electrolytes, organic solvents, acids and gas can be used. Such as ordinary working medium, electric high vacuum ball valve, and also suitable for working medium, such as O2, hydrogen peroxide, methane gas and butadiene, which are widely used in various fields. The ball valve body can be integrated or composed.
