真空蝶阀
真空蝶阀适用于无腐蚀的饱和水蒸气低真空管路上，作为闭路设备。DK941X真空蝶阀为密封型蝶阀，蝶阀两端轴封处用0.25MPa的压力水密封，确保轴封处不泄漏。上海埃非凯阀门有限公司生产的DK941X真空蝶阀结构为双阀座形势，两座之间以及轴端处均为橡胶密封与压力水（压值0.25MPa）相结合形式密封。如用户需要，可在阀体壁上加装电热装置。
Vacuum butterfly valves are suitable for corrosion-free saturated water vapor low vacuum pipelines as closed circuit equipment. DK941X vacuum butterfly valve is a sealed butterfly valve. The seal at both ends of the butterfly valve is sealed with 0.25MPa pressure water to ensure that the seal does not leak. The structure of DK941X vacuum butterfly valve manufactured by Shanghai Efikai Valve Co., Ltd. is double seats. The rubber seal and pressure water (pressure value 0.25MPa) are combined between the two seats and at the end of the shaft. Electric heating device can be installed on valve body wall if user needs.
