Overview
斯派莎克破真空器用于在蒸汽系统及相关容器中打破真空状态，特别是在停机或冷却过程中蒸汽冷凝时。 它有助于防止蒸汽体积塌缩后形成负压，从而避免设备发生变形、损坏或运行异常。 因此，在停机行为、排液方式和容器完整性密切相关，而不能被分开看待的场合，破真空器尤为重要。 破真空器通常会与放气、排凝以及其它管道附件一起选型，以建立更稳定、更安全的蒸汽系统。 典型应用包括容器、换热器和其它蒸汽空间，在这些位置，如果发生塌陷或排液延迟，往往会带来本可避免的机械应力。
Continue your vessel protection selection
Vacuum protection is usually tied to the wider behaviour of the steam space during shutdown, cooling and condensate collapse.
See the wider vessel protection range
Return to the wider pipeline ancillaries range when vacuum protection is only one part of a broader venting, drainage or vessel protection arrangement.
Coordinate venting with vacuum protection
Use air vents and air eliminators when the duty also depends on removing non-condensable gases during start-up or normal operation rather than only breaking shutdown vacuum.
Support safer atmospheric discharge
Review diffusers when the protection arrangement also includes discharge to atmosphere and the outlet needs better noise and erosion control.
