进口蝶式止回阀品牌厂家-德国洛克LOCKE-ZH3

一、进口蝶式止回阀描述：

德国LOCKE洛克进口蝶式止回阀由阀体、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。

The butterfly check valve imported from Locke lock, Germany, is composed of valve body, disc, stem, spring and other parts, which are connected by clamp. 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.

三、进口蝶式止回阀结构优点：

1.体积小、重量轻、结构紧凑、便于维修。

2.阀板采用对偶板上加两个扭力弹簧的设计,可使阀板自行速闭。

3.因速闭作用,可防止介质倒流,消除水锤作用强。

4.阀体结构长度尺寸小、刚性好。

5.安装方便,可在水平、垂直两个方向的管路上安装。

6.达到完全密封,水压试验泄漏量为零。

7.使用性能安全可靠,抗干扰性好。

1. Small size, light weight, compact structure, easy to maintain.

2. The valve plate adopts the design of dual plate plus two torsion springs, which can make the valve plate close automatically.

3. Due to the quick closing function, it can prevent the backflow of medium and eliminate the strong effect of water hammer.

4. The length and size of valve body structure are small and the rigidity is good.

5. It is easy to install, and can be installed on horizontal and vertical pipelines.

6. Achieve complete sealing, and the leakage of hydrostatic test is zero.

7. Safe and reliable performance, good anti-interference.
