德國(guó)洛克進(jìn)口對(duì)夾式止回閥品牌

一、進(jìn)口對(duì)夾式止回閥描述：

德國(guó)LOCKE洛克進(jìn)口對(duì)夾式止回閥由閥體、閥瓣、閥桿及彈簧等零件組成,采用對(duì)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(zhǎng)度比一般止回閥短,對(duì)有安裝空間限制的場(chǎng)所最為適用。對(duì)夾式止回閥用于純凈管路及工業(yè)、環(huán)保、水處理、高層建筑給排水管路,阻止介質(zhì)逆向流動(dòng)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.
