进口电动三片式球阀产品概述：

德国《LOCKE》洛克--进口电动三片式球阀采用智能电动执行器及二通球阀阀体组成，适用于两位切断、调节的场合，执行器采用一体化结构，电动执行机构内置伺服系统，输入控制信号(4～20mADC或1～5VDC)及单相电源即可控制运转，智能型电动球阀具有功能强、体积小、轻便宜人、性能可靠、配套简单、流通能力大、特别适合于介质是粘稠，含颗粒，纤维性质的场合。目前进口电动三片式球阀广泛应用于食品、环保、轻工、石油、造纸、化工、教学和科研设备、电力等行业的工业自动控制系统中。

进口电动三片式球阀产品特点：

1．流体阻力小，其阻力系数与同长度的管段相等。

2．结构简单、体积小、重量轻。

3．紧密可靠，球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。

4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。

5．维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。

6．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

7．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

进口电动三片式球阀工作原理：

内螺纹连接球阀及对焊连接球阀分为整体式（一片式）、两段式及三段式。阀座采用弹性密封结构，密封可靠，启闭轻松。阀杆采用有倒密封的下装式结构，阀腔异常升压时，阀杆不会被冲出。二片式、三片式球阀连接形式另有对焊（BW）承插焊（SW），并均可带国际标准ISO支架平台和锁定装置。可设置90°开关定位机构，根据需要加锁以防止误操。

Introduction of imported electric three piece ball valve products:

Locke imported electric three piece ball valve is composed of intelligent electric actuator and two-way ball valve body, which is suitable for two position cut-off and adjustment. The actuator adopts integrated structure, the electric actuator has built-in servo system, and the operation can be controlled by inputting control signal (4 ~ 20mADC or 1 ~ 5VDC) and single-phase power supply. The intelligent electric ball valve has strong function, small volume, high reliability and low cost Light and pleasant, reliable performance, simple matching, large circulation capacity, especially suitable for viscous media, containing particles, fiber properties of the occasion. At present, the imported electric three piece ball valve is widely used in the industrial automatic control system of food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power and other industries.

Features of imported electric three piece ball valve:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

2. Simple structure, small volume and light weight.

3. It is tight and reliable. The sealing surface material of ball valve is widely made of plastic and has good sealing performance. It has also been widely used in vacuum system.

4. Convenient operation, fast opening and closing, from full opening to full closing as long as 90 ° rotation, convenient for remote control.

5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement.

6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface.

7. Wide range of application, diameter from small to several millimeters, to several meters, from high vacuum to high pressure can be applied.

Working principle of imported electric three piece ball valve:

Internal thread connection ball valve and butt welding connection ball valve are divided into integral type (one piece), two-stage type and three-stage type. The valve seat adopts elastic sealing structure, reliable sealing and easy opening and closing. The valve stem adopts a bottom mounted structure with inverted seal, so the valve stem will not be flushed out when the valve chamber is abnormally pressurized. Two piece and three piece ball valves are connected by butt welding (BW) and socket welding (SW), and can be equipped with international standard ISO support platform and locking device. The 90 ° switch positioning mechanism can be set to lock as needed to prevent misoperation.
