進(jìn)口蝸輪蝶閥德國(guó)洛克各種參數(shù)以及說(shuō)明

一、進(jìn)口蝸輪蝶閥產(chǎn)品簡(jiǎn)介：

德國(guó)《LOCKE》洛克進(jìn)口蝸輪蝶閥采用精密的J形彈性密封圈和三偏心多層次金屬硬密封結(jié)構(gòu)，被廣泛用于介質(zhì)溫度≤955℃的治金、電力、石油化工、以及給排水和市政建設(shè)等工業(yè)管道上，作調(diào)節(jié)流量和載斷流體使用。該閥采用三偏心結(jié)構(gòu)，閥座與碟板密封面均采用不同硬度和不銹鋼制作，具有良好的耐腐蝕性，使用壽命長(zhǎng)，本閥軍郵雙向密封功能，產(chǎn)品符合國(guó)際閥門(mén)壓力試驗(yàn)標(biāo)準(zhǔn)。

Locke imported worm gear butterfly valve in Germany adopts precise J-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure, which is widely used in the industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction with medium temperature ≤ 955 ℃ for regulating flow capacity and breaking fluid. The valve adopts three eccentric structure, the sealing surfaces of valve seat and disc plate are made of different hardness and stainless steel, which has good corrosion resistance and long service life. The valve has two-way sealing function of military post, and the product conforms to the international valve pressure test standard.

四、進(jìn)口蝸輪蝶閥結(jié)構(gòu)特點(diǎn)：

1、啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。

2、結(jié)構(gòu)簡(jiǎn)單，外形尺寸小，結(jié)構(gòu)長(zhǎng)度短，體積小，重量輕，適用于大口徑的閥門(mén)。

3、可以運(yùn)送泥漿，在管道口積存液體最少。

4、低壓下，可以實(shí)現(xiàn)良好的密封。

5、調(diào)節(jié)性能好。

6、全開(kāi)時(shí)閥座通道有效流通面積較大，流體阻力較小。

7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。

8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。

9、操作靈活省力，安裝方便。

1. The opening and closing is convenient, quick, labor-saving, low fluid resistance, and can be operated frequently.

2. Simple structure, small size, short length, small volume, light weight, suitable for large caliber valves.

3. It can transport mud and store the least liquid at the pipe mouth.

4. Under low pressure, good sealing can be achieved.

5. Good regulation performance.

6. When the valve is fully opened, the effective flow area of the valve seat channel is larger and the fluid resistance is smaller.

7. The opening and closing torque is small, because the disc on both sides of the shaft is basically the same under the action of the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving.

8. The sealing surface material is generally rubber and plastic, so the low-pressure sealing performance is good.

9. Flexible and labor-saving operation, easy installation.

五、進(jìn)口蝸輪蝶閥適用范圍：

進(jìn)口蝸輪蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保、建筑給排水等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截?cái)嘟橘|(zhì)的流動(dòng)。

The imported worm gear butterfly valve is applicable to the pipelines conveying various corrosive and non corrosive fluid media in the engineering systems of generator, gas, natural gas, liquefied petroleum gas, urban gas, hot and cold air, chemical smelting, power generation and environmental protection, building water supply and drainage, etc., which is used to regulate and cut off the flow of media.
