High-pressure sensitive pressure relief disconnector

The invention discloses a high-pressure sensitive pressure relief disconnector comprising a three-way pressure relief component. One side of the three-way pressure relief component is provided with an upper one-way valve component. One side of the upper one-way valve component is provided with a lower one-way valve component. The three-way pressure relief component comprises a third shell. One side of the third shell is provided with the upper one-way valve component, and the other side of the third shell is provided with an inlet A. According to the arrangement, a combined design is adopted, and the high-pressure sensitive pressure relief disconnector is composed of the lower one-way valve component, the upper one-way valve component and the three-way pressure relief component which can be independently assembled and detected, in this way, production efficiency is improved, and maintenance and changing convenience is achieved. 本发明公开了种高压灵敏泄压断接器，包括三通泄压组件，三通泄压组件的侧安装上单向阀组件，上单向阀组件的侧安装下单向阀组件，三通泄压组件包括第三壳体，第三壳体的侧安装上
