二、進(jìn)口低溫球閥產(chǎn)品簡介：

德國洛克進(jìn)口低溫球閥經(jīng)特殊的低溫處理，將粗加工的零件置于冷卻介質(zhì)中數(shù)小時(shí)（2-6小時(shí)），以釋放應(yīng)力，確保材料的低溫性能，保證精加工尺寸，以防閥門在低溫工況時(shí)，因溫度變化造成變形而導(dǎo)致的泄漏。閥門的裝配與普通閥門也不同，零件需經(jīng)過嚴(yán)格的清洗，除去任何油污，以保證使用性能。

主要適用于乙烯、液化天然氣等化工裝置上，輸出的液態(tài)低溫介質(zhì)如乙烯、液氧、液氫等。這類介質(zhì)不但易燃易爆，而且在升溫時(shí)要?dú)饣?、氣化是體積膨脹數(shù)百倍。而且這些介質(zhì)滲透力強(qiáng)，易泄露，加工制造比較困難。

The low temperature ball valve imported from Germany is specially treated at low temperature. The rough machined parts are placed in the cooling medium for several hours (2-6 hours) to release the stress, ensure the low-temperature performance of the material and ensure the finishing size, so as to prevent the leakage caused by the deformation caused by the temperature change in the low-temperature working condition. Valve assembly and ordinary valve is also different, parts need to be strictly cleaned to remove any oil, in order to ensure the use of performance.

It is mainly used in ethylene, liquefied natural gas and other chemical plants for the output of liquid low-temperature medium such as ethylene, liquid oxygen, liquid hydrogen, etc. This kind of medium is not only inflammable and explosive, but also needs to be gasified and gasified when heating up, which is hundreds of times of volume expansion. Moreover, these media have strong permeability, easy to leak and difficult to manufacture.

三、進(jìn)口低溫球閥產(chǎn)品特點(diǎn)：

1、在低溫介質(zhì)下具有長時(shí)間工作的能力;

2、直接與低溫介質(zhì)接觸的組合件具有防爆和防火結(jié)構(gòu);

3、在低溫工作的材料要保證其低溫性能,以防止摩擦件擦傷;

4、在低溫及無油潤滑的情況下，具有良好的耐摩性。

1. It can work for a long time in low temperature medium;

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.
