进口电动蝶阀安装维护：

1、在安装时，阀瓣要停在关闭的位置上。

2、开启位置应按蝶板的旋转角度来确定。

3、带有旁通阀的蝶阀，开启前应先打开旁通阀。

4、应按制造厂的安装说明书进行安装，重量大的蝶阀，应设置牢固的基础。

5、蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为 0°~90° 之间，旋转到 90° 时，阀门则牌全开状态。

6、如果要求蝶阀作为流量控制使用，主要的是正确选择阀门的尺寸和类型。蝶阀的结构原理尤其适合制作大口径阀门。蝶阀不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用，而且还应用于热电站的冷却水系统。

7、常用的蝶阀有对夹式蝶阀和法兰式蝶阀两种。对夹式蝶阀是用双头螺栓将阀门连接在两管道法兰之间，法兰式蝶阀是阀门上带有法兰，用螺栓将阀门上两端法兰连接在管道法兰上。

8、蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为 0°~90° 之间，旋转到 90° 时，阀门则牌全开状态。

Introduction of imported electric butterfly valve products:

German "lock" - imported electric butterfly valve adopts an integrated structure, which can be controlled by connecting to the 220 VAC power supply, or by adding a control module to input the control signal (4-20 ADC or 1-5 VDC) for regulation and control. It has strong function, small volume, light and pleasant, reliable performance, simple matching and large circulation capacity. For normal temperature and clean media, the valve plate with soft seal (rubber ring and PTFE ring) can be selected to reduce leakage (up to), and the three eccentric hard seal valve body can be selected for high temperature and high pressure conditions. When ordering, please indicate. It can be widely used in food, environmental protection, light industry and petroleum.

Features of imported electric butterfly valve:

1. The design is novel, reasonable, special structure, light weight and quick opening and closing.

2. Small operating torque, convenient operation, labor saving and dexterity.

3. It can be installed in any position, easy to maintain.

4. The sealing parts can be replaced, the sealing performance is reliable, and the bidirectional sealing has zero leakage.

5. The sealing material has the characteristics of aging resistance, weak corrosion resistance and long service life.

Installation and maintenance of imported electric butterfly valve:

1. During installation, the disc should stop at the closed position.

2. The opening position should be determined according to the rotation angle of the butterfly plate.

3. For butterfly valve with bypass valve, the bypass valve should be opened before opening.

4. The installation shall be carried out according to the installation instructions of the manufacturer, and the heavy butterfly valve shall be provided with a firm foundation.

5. The butterfly plate of butterfly valve is installed in the diameter direction of pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with the rotation angle between 0 ° and 90 ° and when it rotates to 90 ° the valve is fully open.

6. If the butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of butterfly valve is especially suitable for making large diameter valve. Butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power station.

7. There are two kinds of butterfly valves in common use, namely, clamp type butterfly valve and flange type butterfly valve. Clip on butterfly valve is to connect the valve between two pipe flanges with stud bolts. Flange butterfly valve has flange on the valve, and both ends of the valve are connected to the pipe flange with bolts.

8. The butterfly plate of butterfly valve is installed in the diameter direction of pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with the rotation angle between 0 ° and 90 ° and when it rotates to 90 ° the valve is fully open.
