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...

Abstract

The invention discloses a membrane auxiliary type compression bar destabilizing trigger type pressure relief device applied to the micro-pressure working condition. The membrane auxiliary type compression bar destabilizing trigger type pressure relief device mainly comprises a valve body, a valve clack, a valve deck, a lock arm, a lock catch, a membrane shell body, a membrane, a connecting rod, a hinge, a linkage tumbler, a slender bar, a nut, a bar cage and a pressure communicating pipe. The medium pressure is introduced to the shell body to be played on the membrane through the pressure communicating pipe, thrust load is produced, and the load is loaded on the slender bar through the connecting rod integrated with the membrane. Under the normal working condition, the load acting on the slender bar is less than the critical load of the slender bar, and the slender bar remains stable, the lock catch is locked in the lock arm at this moment, and the valve clack is fixed and can not take off, so that the device is in a closed state; under the abnormal working condition, the slender bar is destabilized and loses the bearing capacity, the membrane and the connecting rod are pushed by the medium pressure to move and drive the linkage tumbler to act, the lock arm is driven by the linkage tumbler to move, the lock catch is released from the lock catch, and the valve clack is disengaged from the sealing face of the valve body at this moment, so that the purpose of pressure relief is achieved.

Description

technical field [0001] The invention relates to a pressure relief device, more particularly to a pressure relief device that can be automatically opened when the pressure exceeds a set value. Background technique [0002] In order to protect oil storage tanks and other equipment from overpressure damage, it is necessary to set up a pressure relief device that automatically opens when the pressure in the storage tank exceeds the limit. The permissible overpressure of petroleum storage tanks is usually very low, which puts high demands on the pressure relief device. [0003] The invention is a membrane-assisted pressure-rod instability-triggered pressure relief device suitable for micro-pressure working conditions, and its design is based on the principles of pressure-rod stability and pressure-rod instability. The pressure of the medium acts on the diaphragm to generate a thrust load, which is loaded on the slender rod through the connecting rod integrated with the diaphragm...
