進口微阻緩閉止回閥德國洛克供應(yīng)各種規(guī)格與型號 

一、進口微阻緩閉止回閥描述：

德國LOCKE洛克進口微阻緩閉止回閥由閥體、閥蓋、閥瓣、閥軸及調(diào)節(jié)閥等組成，安裝在水泵出口處用來防止介質(zhì)逆流和消除破壞性水錘，并能有效地減少閥門關(guān)閉的水錘壓力，可保障管網(wǎng)安全運行。它具有閥瓣輕、開度大、節(jié)電效果顯著，流體阻力小，水錘消除機構(gòu)設(shè)計新穎，密封性能穩(wěn)定可靠、耐磨損、使用壽命長、運行平穩(wěn)、無震動、無噪音等特點。

The micro resistance slow closing check valve imported from Locke lock, Germany, is composed of valve body, valve cover, valve disc, valve shaft and regulating valve. It is installed at the outlet of water pump to prevent backflow of medium and eliminate destructive water hammer. It can effectively reduce the water hammer pressure of valve closure and ensure the safe operation of pipe network. It has the characteristics of light disc, large opening, remarkable power saving effect, small fluid resistance, novel design of water hammer eliminating mechanism, stable and reliable sealing performance, wear resistance, long service life, stable operation, no vibration, no noise, etc.

二、進口微阻緩閉止回閥技術(shù)參數(shù)：

1、公稱壓力：1.0～2.5MPa

2、公稱通經(jīng)：40～1200mm

3、適用介質(zhì)：水、弱腐蝕性液體

4適用溫度：0～80℃（如需要，可達200℃）

5、緩閉性能：介質(zhì)壓力≥0.19Mpa具有緩閉性能

6、緩閉時間：1-60秒內(nèi)任意調(diào)節(jié)

1. Nominal pressure: 1.0 ～ 2.5MPa

2. Nominal diameter: 40-1200mm

3. Applicable medium: water, weak corrosive liquid

4 applicable temperature: 0-80 ℃ (up to 200 ℃ if necessary)

5. Slow closing performance: medium pressure ≥ 0.19mpa with slow closing performance

6. Slow closing time: any adjustment within 1-60 seconds

三、進口微阻緩閉止回閥結(jié)構(gòu)特點：

1、體形小、重量輕、結(jié)構(gòu)長度只有旋啟式止回閥的三分之一左右。

2、緩閉系統(tǒng)性能優(yōu)良，不受管道中介質(zhì)的影響，閥瓣先速關(guān)后緩閉，可防止破環(huán)性水錘。

3、橡膠軟密封，封閉性能好，耐磨損，使用壽命長。

4、橡膠緩沖，啟閉平穩(wěn)，無震動，無噪音。

5、比老式止回閥流阻小，有明顯的節(jié)能效果。

1. Small size, light weight, structure length is only about one third of the swing check valve.

2. The slow closing system has excellent performance and is not affected by the medium in the pipeline. The valve disc is closed quickly first and then closed slowly, which can prevent the water hammer.

3. Rubber soft seal, good sealing performance, wear resistance, long service life.

4. Rubber buffer, stable opening and closing, no vibration, no noise.

5. Compared with the old check valve, it has smaller flow resistance and obvious energy saving effect.
