【進口法蘭鍛造閘閥】詳細說明：

閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直，作為截止介質(zhì)使用，在全開時整個流通直通，此時介質(zhì)運行的壓力損失小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開或全閉的工況，不適用于作為調(diào)節(jié)或節(jié)流使用。閘閥流體阻力小，適用的壓力、溫度范圍大，介質(zhì)流動方向不受限制，密封性能良好。廣泛適用于食品、醫(yī)藥、石油、化工、天然氣、鋼鐵、環(huán)保、造紙等輸送管路中做介質(zhì)切斷或流通

The opening and closing part of the gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. It is used as the cut-off medium. When the gate valve is fully opened, the whole flow is through, and the pressure loss of the medium is the smallest. Gate valves are generally suitable for conditions that do not require frequent opening and closing and keep the gate fully open or closed. They are not suitable for use as regulation or throttling. The gate valve has small fluid resistance, wide range of pressure and temperature, unlimited flow direction of medium and good sealing performance. Widely used in food, medicine, petroleum, chemical industry, natural gas, iron and steel, environmental protection, paper and other transportation pipelines as media cut off or circulation

【進口法蘭鍛造閘閥】優(yōu)點：

1、流體阻力小 , 密封面受介質(zhì)的忡刷和侵蝕小。
