Embodiment Construction
[0011] A diaphragm-assisted pressure rod instability trigger type pressure relief device suitable for micro-pressure conditions, the main components include valve body 1, valve disc 2, valve cover 3, lock arm 4, lock buckle 5, and diaphragm housing 6. Diaphragm 7, connecting rod 8, hinge 9, linkage rotating arm 10, slender rod 11, nut 12, rod cage 13 and pressure communication pipe 14. See figure 1 .
[0012] Wherein, the locking arm 4, the locking buckle 5, the diaphragm 7, the connecting rod 8, the hinge 9, the linkage rotating arm 10, and the slender rod 11 jointly constitute the trigger mechanism of the device. The elongated rod 11 is the trigger part of the device, and one end thereof is connected with the connecting rod 8 , and the other end is connected with the nut 12 installed on the rod cage 13 .
[0013] The medium pressure enters the diaphragm housing 6 through the pressure communication pipe 14 and acts on the diaphragm 7 to generate a thrust load. The thrust lo...
