进口偏心蝶阀产品信息：

美国《LAINE》莱恩--进口偏心蝶阀（简称gao性能蝶阀）阀板与密封圈采用偏心结构，具有结构紧凑、切断性能好、使用寿命长等特点，兼备调节和切断两种功能。应用于化工、电力、轻纺、食品、医药、造纸等工业部门及市政工程、水厂等管道对自来水、污水、油类液体或空气、煤气、天然气、水蒸气等介质进行截止或调节流量控制。

Laine imported eccentric butterfly valve (referred to as Gao performance butterfly valve) of the United States adopts eccentric structure for valve plate and sealing ring, which has the characteristics of compact structure, good cutting performance and long service life. It also has two functions of regulation and cutting. It is used in chemical industry, electric power, light textile, food, medicine, papermaking and other industrial departments, municipal engineering, water plant and other pipelines to cut off or regulate the flow control of tap water, sewage, oil liquid or air, gas, natural gas, steam and other media.

进口偏心蝶阀特点：

1、蝶板密封圈为软硬层叠式金属片,具有金属密封和弹性密封的双重优点,无论在低温和高温情况下,均具有优良的密封性能。

2、采用偏心结构,阀座与蝶板无乎无磨擦,具有越关越紧的密封功能。

3、阀体密封面,采用堆焊钴基硬质合金,密封面抗磨损,使用帮命长。

4、结构合理,操作灵活、省力、方便,不受力介质压力的高、底影响,密封性能ke靠,使用寿命长. 多功能性 抗高温,抗腐蚀,广范用于石油化工,食品、医药、造纸、水电、船舶、给排水、冶金、能源等系统的管路上,适用于多种腐蚀性的气体,液体,半液体以及固体粉末介质。

1. The butterfly plate seal ring is a soft and hard laminated metal sheet, which has the dual advantages of metal seal and elastic seal. It has excellent sealing performance both at low temperature and high temperature.

2. The eccentric structure is adopted, and there is almost no friction between the valve seat and the butterfly plate. It has the sealing function of closing and tightening.

3. The sealing surface of the valve body is overlaid with cobalt based cemented carbide. The sealing surface is wear-resistant and has a long service life.

4. The utility model has the advantages of reasonable structure, flexible operation, labor saving and convenience, is not affected by the high and bottom pressure of the stress medium, reliable sealing performance, long service life, multi-function, high temperature resistance and corrosion resistance. It is widely used in the pipelines of petrochemical, food, medicine, papermaking, hydropower, shipbuilding, water supply and drainage, metallurgy, energy and other systems, and is suitable for a variety of corrosive gases and liquids, Semi liquid and solid powder media.

进口偏心蝶阀安装维护：

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。

1. During installation, the valve disc shall stop at the closed position.

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

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

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