一种脱落型安全泄压装置
摘要：
一种脱落型安全泄压装置，属于安全装备技术领域，涉及到流体压力的安全泄压装置。由夹持器上页、脱落片、O形圈、容器凸缘兼夹持器下页组成；依靠O形圈的弹性变形量控制夹持器与脱落片之间的夹持力，从而保证脱落片在设定的爆破压力脱落。夹持器上页内径介于O形圈内外径之间；爆破片与夹持器上页接触面的径向距离为2－10mm；正常工作状态下，夹持器上页与容器凸缘兼夹持器下页保持接触状态，以确保O形圈的弹性变形量。本发明可实现超低压、密封要求高的特殊用户要求。同时制造方法简单，成本低廉。特别适用于作为超低压设备的安全附件。
摘要（英）：

A device is composed of holder upper limb, knockout sheet O shaped ring, container flange and holder down limb. The holding force between holder and knockout sheet is controlled by elastic deformation size of O shaped ring to ensure knocked out to knockout sheet at the designed explosive pressure. The internal diameter of holder upper limb is in between internal and external diameters of O shaped ring, axial distance of explosive sheet and upper limb contact surface of holder is 2-10 mm, at normal operating state holder upper limb remains contact state with holder down limb and container flange to ensure elastic deformation size of O shaped ring.
