生产厂家 产品结构特点 Construction features 伸缩阀适用于温度≤425℃,公称压力≤1.6MPa的食品、医药、化工、石油、电力、轻纺、造纸等给排水、气体管道上作调节流量和截流介质的作用,具有补偿管道热胀冷缩的功能。 其主要特点为: 1、设计新颖、合理,结构,重量轻,操作方便,启闭迅速; 2、伸缩蝶阀除了能作调节和截流作用,补偿管道温差所产生的热胀冷缩功能外,还能为安装更换、维修阀门提供方便; 3、密封部位可调节更换,密封性能可靠等特点。 Expansion valve is suitable for the temperature of 425℃ or less and nominal pressure of 1.6 MPa or less food, medicine, chemical, petroleum, electric power, textile,paper and other water supply and drainage, for adjusting flux on the gas pipeline and intercepting the role of the media, has the function of compensating pipe heat bilges cold shrink. Its main features are: 1. The design is novel and reasonable, the structure is unique, the weight is light, the operation is convenient, the opening and closing fast; 2. In addition to adjusting and intercepting the butterfly valve, it can also provide convenient installation and replacement and maintenance of valve. 3. The sealing parts can be adjusted and replaced, and the sealing performance is reliable. 产品特征 Spericfications 适用介质:食品、石油、化工、电力、造纸和 适用温度:-29~350℃ 驱动方式:手动、气动、电动、液动等 公称压力:0.6~1.6MPa 公称通径:DN100~2000mm Applicable media: Gas, dust and flue gas Applicable temperature: -29~350℃ Driver: manual, pneumatic, electric, hydraulic, etc Nominal pressure: 0.6~1.6MPa Nominal size: DN100~2000mm 技术规范 Technical specification 主要零件和材质 Main parts and materials 蝶阀结构长度和外接尺寸 Main connection dimensions 试验压力 Test prssure
