進口蝶式止回閥品牌廠家-德國洛克LOCKE-ZH3

一、進口蝶式止回閥描述：

德國LOCKE洛克進口蝶式止回閥由閥體、閥瓣、閥桿及彈簧等零件組成，采用對夾連接。由于閥瓣的關(guān)閉行程短，并且有彈簧加載，可顯著減少水錘現(xiàn)象。該閥主要適用于城市、工業(yè)及高層建筑給水、排水管網(wǎng)上。由于其結(jié)構(gòu)長度比一般止回閥短，對有安裝空間限制的場所最為適用。

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、進口蝶式止回閥結(jié)構(gòu)優(yōu)點：

1.體積小、重量輕、結(jié)構(gòu)緊湊、便于維修。

2.閥板采用對偶板上加兩個扭力彈簧的設(shè)計,可使閥板自行速閉。

3.因速閉作用,可防止介質(zhì)倒流,消除水錘作用強。

4.閥體結(jié)構(gòu)長度尺寸小、剛性好。

5.安裝方便,可在水平、垂直兩個方向的管路上安裝。

6.達到完全密封,水壓試驗泄漏量為零。

7.使用性能安全可靠,抗干擾性好。

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.
