爆破片
Bursting discs are safety devices designed for installation between a 3-way valve and a safety valve. They are used when a greater tightness is required, by controlling the space between the bursting disc and the safety valve and to protect the safety valve against the damaging effects of the working medium e.g. soiling, sticking, corrosion.
爆破片是设计用于安装在三通阀和安全阀之间的安全装置。当需要更高的密封性时使用它们，通过控制爆破片和安全阀之间的空间并保护安全阀免受工作介质的破坏作用，例如污染、粘连、腐蚀。
技术特征
- 采用钢或不锈钢
- 工作介质：符合EN 378-1的乙二醇基冷盐水制冷剂, 例如NH3、R22、R134a 以及与冷冻机油的混合物；中性、气体和液体介质；乙二醇基冷盐水
- 它的使用不允许在最大工作压力高于低爆破公差 90% 的系统中使用爆破片。爆破片适用于气体，但不适用于液体。爆破公差为 +/- 10% 或可选的 +/-5%。

Innovating for impact: shaping better solutions for customers
Industrial production is being asked to use fewer resources, become smarter and keep equipment productive for longer. At GEA, that is changing how innovation happens: engineering, customer insight, digital expertise and service come together earlier – when a solution can still be shaped at its core.
