Overview

The BT-ZW-F double rated bursting disc with positive and negative arches prevents pressure and vacuum. The combination of the double rated bursting disc with positive and negative arches prevents pressure and vacuum, achieving two functions of bursting disc: on the one hand, it is a three-layer positive arch bursting disc ODV, and on the other hand, it is a reverse arch buckle type bursting disc KUB.

Product Details

Double rated bursting discs BT-ZW-F with positive and negative arches to prevent pressure and vacuum
The BT-ZW-F dual rated bursting disc with positive and negative arches prevents pressure and vacuum, and combines the functions of two bursting discs with bidirectional action: on the one hand, it is a three-layer positive arch bursting disc ODV, and on the other hand, it is a negative arch buckle type bursting disc KUB.

Double rated bursting discs prevent pressure and vacuum

Different reaction pressures can be achieved. It protects against positive pressure in one direction and negative vacuum pressure in the opposite direction. The function of two bursting discs in a single component. The BT-ZW-F bursting disc provides free maintenance benefits, reliability, and firmness, even at low reaction pressures. ZW opens without fragments and is suitable for both liquid and gas in both directions. Low strength tanks are a typical application of this type of explosive disc. The negative pressure response pressure in the direction of vacuum is fixed by the positive arch blasting layer and its fracture point. The protection in the positive pressure direction is based on the KUB pin principle. The sealing function is achieved by polytetrafluoroethylene or FEP film. Explosive discs are directly installed between flanges or corner rings. A separate gripper is not required. Simultaneously monitor the condition of bidirectional bursting discs by sensing the SNR of the signal unit.
