Roman Seliger(罗曼塞立格)高流速致断螺栓式拉断阀ABVL型

The breakaway coupling series with high flow capacity and load-limited triggering via breaking pins

High-performance solution for short loading times and/or low pressure losses.

The ABVL series was particularly developed for loading processes, in which both an as high as possible flow capacity and low pressure loss are as important as the safety of a breakaway coupling.

ABVL series breakaway couplings provide the same functions as those of the ABV series, ABV series, but have a much higher flow capacity due to their flow-optimised design:

The ABVL series breakaway couplings separate the line at a defined tensile load. This should be selected with a sufficient safety margin below the load limit of the line, such as the maximum tensile load of a hose line. Both coupling halves are equipped with a non-return valve each that allows to close the line impermeably when it is separated and to exclude that the medium escapes into the environment.

The basic principle:

Along with the accustomed safe triggering as seen in the ABV series, this series minimises the pressure loss within the coupling. This saves energy and time during the loading process.

The ABVL series couplings consist of two almost identical coupling halves. These are connected via a pair of flanges by means of three breaking pins during normal operation. The flanged connection has no overlaps, so tensile forces acting on the line are directly transmitted to the breaking pins. The ABV function is available without limitation of the load angle. When pure axial load is applied, the tensile force is distributed evenly to all three pins so that the threshold for triggering is the highest here. However, when lateral tensile forces are applied, the load is distributed unevenly to the breaking pins; the load increases with the size of the angle to the coupling axis. The load then increasingly focuses on one or max. two pins, so that the planned separation takes place at a lower threshold value.

If their tensile strength is exceeded, the pins break and the flanged connection is loosened. In this case, the separated coupling halves must be closed immediately; for this purpose the two housing halves are equipped with spring-loaded non-return valves. In the operating state, they brace each other and keep the flow cross-section open. In the case of separation the mutual support effect of the valves no longer exists so that they abruptly close each cross section being released.

 

罗曼塞立格高流速拉断阀ABVL在业界同口径的拉断阀中实现最快的流通速度和最小的压力损失,该产品在欧洲和北美各大港口都有应用,特别适合对装卸料时间有严格要求的客户,在投入初期就能通过节省的港口停泊费和人力成本来收回产品的投资。

ABVL通过模拟海豚的流线型阀体设计,将阻尼降低到最低限度,同时采用耐腐蚀性极佳的不锈钢材质保证在港口使用的耐久性。
