本阀门是一种橡胶（NBR）密封蝶阀，广泛应用于电力、水力、冶金、化工、城建等行业的给排水管路系统，作为控制介质流量的启闭或调节装置。沟槽式（卡箍）蝶阀是引进美国和德国同类*产品而设计制造的一种新型连接阀门。它具有一安装快速、简易、安全不受安装场地限制、便于管道与阀门的维修保养，有隔振隔音与一定的角度范围内克服管道连接同轴而产生的偏差。解决温差所产生的热胀冷缩等优点。

The valve is a rubber (NBR) sealed butterfly valve, which is widely used in water supply and drainage pipeline systems in electric power, hydraulic, metallurgy, chemical industry, urban construction and other industries as an opening and closing or regulating device for controlling medium flow. Grooved (clamp) butterfly valve is a new connecting valve designed and manufactured by introducing similar advanced products from the United States and Germany. The utility model has the advantages of fast, simple and safe installation, is not limited by the installation site, is convenient for the maintenance of pipelines and valves, has vibration isolation and sound insulation, and overcomes the deviation caused by the coaxial connection of pipelines within a certain angle range. Solve the advantages of thermal expansion and cold contraction caused by temperature difference.
