Zook ZVAC-ZPOS爆发盘 - 超低压

The Zook ZVac-ZPos Bursting Disc Series is a range of bi-directional rupture disc and holder assemblies designed to relieve between 1-30” WC in one direction and 2-150 psi in the other direction uniquely protecting processing, fermentation, storage tanks and low strength vessels from vacuum implosion or over-pressure failure in a single device. Both designs relieve ultra-low pressure settings. The Z-VAC allows ultra-low pressure relief in the vacuum direction starting at 1” (25 mm) of water column differential and features user-friendly replaceable knife blades to ensure optimum performance. The Z-POS allows ultra-low pressure relief in the positive direction starting at 1” (25mm) of water column differential. This range of composite reverse acting discs is ideal for the relief of vacuum and overpressure situations.

Both products offer non-fragmenting opening and as a result of their modular content can be offered to meet a broad range of non-standard specifications and applications.

Z-VAC的工作原理：
超低真空缓解由激光切割可折带控制。系统中的真空压力将特氟龙密封压在腰带上，将其偏向于持有人内置的剃须刀刀片。当真空压力接近浮雕时，腰带塌陷，使密封件可以被刀片切开。当破裂盘可缓解负（真空）方向时，激光切割正压控制帽或非开放压力支撑帽可提供最佳流动。正压释放由激光切割的顶部金属控制盖控制。在系统中发生加压时，在张力载荷下，突发帽会减轻正压。

Z-POS的工作原理：
正压释放由腰带控制。当系统中的压力接近正爆裂设置时，特氟龙密封板压在腰带上，将其偏向持有人出口中内置的刀叶片。当腰带通过刀叶片时，密封将减轻正压。激光在突发盖或非开放压力支撑帽上切开孔
当破裂盘可缓解正压方向时，提供最佳流量。真空缓解由金属顶部控制。在张力载荷下，爆破盖可缓解负（真空）压力。
