進(jìn)口低溫法蘭截止閥品牌德國(guó)洛克

一、進(jìn)口低溫法蘭截止閥設(shè)計(jì)要求:

1、閥門在低溫介質(zhì)及周圍環(huán)境溫度下應(yīng)具有長(zhǎng)時(shí)間工作的能力。

2、低溫介質(zhì)不應(yīng)對(duì)手輪操作及填料密封性能產(chǎn)生有害的影響。

3、直接與低溫介質(zhì)接觸的閥門組合件應(yīng)具有防爆和防火結(jié)構(gòu)。

4、在低溫下工作的閥門組合件無(wú)法潤(rùn)滑，所以需要采取結(jié)構(gòu)措施，以防止摩擦件擦傷。

5、閥門不應(yīng)成為低溫系統(tǒng)的一個(gè)顯著熱源。這是因?yàn)闊崃康牧魅氤档蜔嵝释?，如流入過(guò)多，還會(huì)使內(nèi)部流體急速蒸發(fā)，產(chǎn)生異常升壓，造成危險(xiǎn)。

1. The valve shall be able to work for a long time under low temperature medium and ambient temperature.

2. Low temperature medium should not have harmful effect on handwheel operation and packing sealing performance.

3. The valve assembly directly contacting with low temperature medium shall have explosion-proof and fireproof structure.

4. The valve assembly working at low temperature cannot be lubricated, so structural measures should be taken to prevent abrasion of friction parts.

5. Valves should not be a significant source of heat for cryogenic systems. This is because the inflow of heat not only reduces the thermal efficiency, but also makes the internal fluid evaporate rapidly, resulting in abnormal pressure rise, causing danger.

2. The assembly directly contacting with low temperature medium has explosion-proof and fireproof structure;

3. The material working at low temperature should ensure its low temperature performance to prevent abrasion of friction parts;

4. It has good friction resistance at low temperature and without oil lubrication.

三、進(jìn)口低溫法蘭截止閥產(chǎn)品簡(jiǎn)介：

低溫閥門著名品牌德國(guó)LOCKE洛克生產(chǎn)的進(jìn)口低溫法蘭截止閥適用于低溫液體貯運(yùn)設(shè)備的管理系統(tǒng)，具有開關(guān)靈活、密封可靠的特點(diǎn)，也可用于其他低溫和深冷介質(zhì)的管理系統(tǒng)。

The imported low-temperature flange globe valve produced by German locklock, a famous brand of cryogenic valve, is suitable for the management system of cryogenic liquid storage and transportation equipment. It has the characteristics of flexible switch and reliable sealing, and can also be used in the management system of other cryogenic and cryogenic media.
