斯派莎克VB21破真空器
VB21斯派莎克不锈钢破真空器用于在蒸汽系统压力低于大气压力时,破除管道真空。保护设备不受真空损坏,同时,可有效排除管道和换热器中的冷凝水。
工作原理:
VB14、VB21真空破坏阀在形成真空的地方将大气压力引入蒸汽或者液体系统中,引入大气以后,系统内的冷凝水就可以从高往低处流,从蒸汽设备疏水阀排出,因此,VB14、VB21破真空器对于工艺系统的正常排液是十分必要的。

特点:
1、有效的保护设备免受真空的破坏。
2、吸进大气压力使管道内与设备的压力平衡并系统有效地排除管道内与设备真空现象。
3、结构小巧,可靠和耐腐蚀不锈钢材质的设计。
Spirax Sarco VB21 kinds of small general-breaking vacuum, mainly for condensing vapor (steam) and liquid systems. For, when the steam system pressure below atmospheric pressure, the vacuum pipe break. · Protect equipment from damage to the vacuum · At the same time, can effectively exclude pipes and heat exchanger condensate. Installation VB21 air valve must be installed in a vertical position, the system connector located on the bottom of the vacuum break valve. As for the steam system, emptying valve must be installed on the highest point of the system, and to prevent condensation of water valve is not invaded.
