Problems solved by technology

However, in some occasions, the performance of the medium will change greatly due to temperature changes, which will have a great impact on the safety of the equipment. At this time, the rupture disc will not burst because the equipment does not reach the predetermined burst pressure. Unsafe factors caused by changes cannot be ruled out

Embodiment

[0017] A temperature and pressure double-acting explosion-proof device, its structure is as follows figure 1 As shown, the device includes a bursting disc 1, a fuse pin 2, a connector 3, a sealing gasket 4, an adapter frame 5, a fixing frame 6 and a hinge 7. The device is installed in the equipment casing 8, and the adapter frame 5 is located The upper part of the fixed frame 6 is provided with a sealing gasket 4, which acts as a seal under the pre-tightening force of the fuse pin 2. The bursting disc 1 is arranged at the lower part of the fixed frame 6, and the bursting disc 1 is used to control the blasting at the set temperature. Pressure is the set pressure relief element. Different bursting disc structures can be selected according to different set relief pressures and relief diameters. Once the pressure in the equipment reaches the set burst pressure, bursting disc 1 will open and release pressure, the direction of pressure relief is vertically upward. The hinge 7 is lo...

Abstract

The invention relates to a temperature and pressure dual acting explosion-proof device, which comprises an adapting rack, a fixed bracket, a sealing gasket, a rupture disc, a hinge, a connecting member and a fused pin, wherein the adapting rack is arranged at the upper part of the fixed bracket; the sealing gasket is arranged between the adapting rack and the fixed bracket; the rupture disc is arranged at the lower part of the fixed bracket; the hinge is arranged at the right side of the temperature and pressure dual acting explosion-proof device; two ends of the hinge are respectively connected with the adapting rack and the fixed bracket; the connecting member is arranged at the left side of the temperature and pressure dual acting explosion-proof device; the upper end of the connecting member is connected with the adapting rack; and the lower end of the connecting member is connected with the fixed bracket through the fused pin. Compared with the prior art, the temperature and pressure dual acting explosion-proof device has a simple structure, convenience in use and a wider application range; in addition, the aim of release can be achieved under the condition of set temperature or set pressure; and more potential safety hazards caused by change of the performance of a medium due to temperature change are overcome.

Description

technical field [0001] The invention relates to the field of burst discs, in particular to a temperature-pressure dual-action explosion-proof device. Background technique [0002] The bursting disc device is an emergency overpressure relief device driven by differential pressure and non-automatically closed. It is mainly used to protect pressure vessels, pipelines or other closed systems from damage caused by excessive overpressure or vacuum. Bursting disc devices are now widely used in chemical, pharmaceutical, environmental protection, steel, electric power and other industries that need protection. [0003] Conventional rupture discs can only burst at a certain set pressure, and their burst pressure is determined by performing a burst pressure test at a specified temperature. However, in some occasions, the performance of the medium is greatly changed due to temperature changes, which will have a great impact on the safety of the equipment. At this time, the rupture disc...
