进口对夹式止回阀品牌德国洛克

一、进口对夹式止回阀描述：

德国LOCKE洛克进口对夹式止回阀由阀体、阀瓣、阀杆及弹簧等零件组成,采用对夹连接。由于阀瓣的关闭行程短,并且有弹簧加载,可显著减少水锤现象。该阀主要适用于城市、工业及高层建筑给水、排水管网上。由于其结构长度比一般止回阀短,对有安装空间限制的场所最为适用。对夹式止回阀用于纯净管路及工业、环保、水处理、高层建筑给排水管路,阻止介质逆向流动之用。

The wafer check valve imported from Locke lock, Germany, is composed of valve body, disc, stem, spring and other parts, which are connected by wafer. Due to the short closing stroke of the disc and the spring loading, the water hammer phenomenon can be significantly reduced. The valve is mainly applicable to the water supply and drainage network of urban, industrial and high-rise buildings. Because its structure length is shorter than general check valve, it is most suitable for places with installation space limitation. The wafer check valve is used for pure pipeline and industrial, environmental protection, water treatment, high-rise building water supply and drainage pipeline to prevent the reverse flow of media.

二、进口对夹式止回阀结构优点：

1、结构长度短．其结构长度只有传统法兰止回阀的1/4～1/8;

2、体积小,、重量轻,其重量只有传统法兰止回目的1/4～1/20;

3、阀瓣尖闭快速．水锤压力小：

4、水平管道或垂直管道均可使月．安装方便；

5、流道通畅、流体阻力小．

6、动作i敏、密封性能好;

7、目瓣行程短、关阀冲击力小;

8、整体结构、简单紧凑、造型美观

9、使月寿命长、可靠性高。

1. Its structure length is only 1 / 4-1 / 8 of the traditional flange check valve;

2. Small volume, light weight, its weight is only 1 / 4-1 / 20 of the traditional flange check;

3. Quick closing of valve disc tip, small water hammer pressure:

4. The horizontal pipe or vertical pipe can make the month and installation convenient;

5. The flow passage is smooth and the fluid resistance is small

6. Action I sensitive, good sealing performance;

7. Short stroke of eye flap and small impact force of valve closing;

8. Overall structure, simple and compact, beautiful shape

9. Long monthly life and high reliability.
