Product name: -196 ℃ low temperature 316L pneumatic ball valve

Model: DQ621F

Caliber: DN6-DN50mm

Pressure: 1.6-42.0

Material: Stainless steel

Product introduction

DQ621F pneumatic low temperature ball valve undergoes special low temperature treatment. The rough parts are placed in the cooling medium for several hours (2-8 hours) to release the stress, ensure the low temperature performance of the material, and ensure the finished size to prevent the valve from working at low temperature. In some cases, leakage due to deformation due to temperature changes. For medium temperatures above -50 ° C, a long neck structure is generally not used. For ball valves with a medium temperature below -50 ° C, the neck length is generally 250mm, or determined according to our company's design and calculation. Pneumatic ultra-low temperature ball valve is mainly used to output liquid cryogenic medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc. It is one of the important equipment indispensable in petrochemical, air separation, natural gas and other industries. Determines whether it is safe, economical and sustainable

: -196 ℃ low temperature 316L pneumatic ball valve product features :

-100 ℃的所有阀门零件按照相关规定进行深冷处理,以防止材料产生低温脆性以及低温下因材料相变引起体积变化 . 1. Cryogenic treatment of all valve parts with a temperature lower than -100 ℃ in accordance with relevant regulations to prevent low-temperature brittleness of the material and volume change due to material phase change at low temperature .

0 ℃以上,有效防止填料因工作温度过低而造成密封性能降低甚至密封失效,同时方便对阀门包裹保温材料,防止冷能损失 . 2. The long neck structure is adopted to make the working temperature of the packing above 0 ℃, which can effectively prevent the packing from reducing the sealing performance or even the sealing failure due to the low working temperature. At the same time, it is convenient to wrap the insulation material for the valve to prevent the loss of cold energy .

. 3.The floating ball valve adopts an inlet pressure relief outlet seal design, which effectively prevents the abnormal pressure rise in the middle cavity due to temperature changes and ensures the safe operation of the valve and pipeline .

. 4.Double-layer valve stem packing and counter pressure disc type shrapnel device .
