德國洛克進(jìn)口氣動(dòng)閘閥的工作原理與使用方法

一、進(jìn)口氣動(dòng)閘閥產(chǎn)品描述：

德國《LOCKE》洛克進(jìn)口氣動(dòng)閘閥(Pneumatic valve)（氣動(dòng)不銹鋼閘閥，氣動(dòng)法蘭閘閥，氣動(dòng)襯氟閘閥），借助壓縮空氣驅(qū)動(dòng)的閥門，閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來密封，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。

The pneumatic valve (pneumatic stainless steel gate valve, pneumatic flange gate valve, pneumatic lining fluorine gate valve) imported from Locke, Germany, is driven by compressed air. When the gate valve is closed, the sealing surface can only be sealed by the medium pressure, that is, the sealing surface of the gate valve is pressed to the seat on the other side by the medium pressure to ensure the sealing surface, which is self sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate shall be forced to the valve seat by external force to ensure the sealing of the sealing surface.

二、進(jìn)口氣動(dòng)閘閥結(jié)構(gòu)優(yōu)點(diǎn)：

1、選材考究，符合國內(nèi)外相關(guān)標(biāo)準(zhǔn)，材料的全面質(zhì)量高。

2、符合國內(nèi)外先進(jìn)標(biāo)準(zhǔn)的要求，密封可靠、性能優(yōu)良、造型美觀。

3、密封副配對(duì)先進(jìn)合理，閘板和閥座的密封面采用不同硬度的司太立（Stellite）鈷基硬質(zhì)合金堆焊而成，密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。

4、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理，有良好的抗腐蝕性、抗擦傷性和耐磨性。

5、采用楔式彈性閘板結(jié)構(gòu)，中大口徑設(shè)置推力軸承，磨擦力小，并配有撞擊手動(dòng)，啟閉輕松自如。

6、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面形式，滿足各種工程需要及用戶要求。

1. The material selection is exquisite, in line with the relevant standards at home and abroad, and the overall quality of the material is high.

2. It meets the requirements of advanced standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance.

3. The sealing pair is advanced and reasonable. The sealing surface of ram and valve seat is overlaid with Stellite cobalt based hard alloy with different hardness. It has reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long service life.

4. After tempering and surface nitriding treatment, the valve rod has good corrosion resistance, abrasion resistance and wear resistance.

5. Wedge type elastic ram structure is adopted, thrust bearing is set in medium and large diameter, with small friction force and manual impact, easy opening and closing.

6. It can adopt various piping flange standards and flange sealing surface forms to meet various engineering needs and user requirements.
