Problems solved by technology

[0004] Due to technical requirements, the closed container for storing materials needs to connect the closed space with the outside world as needed, but the efficiency of manual operation is low
[0005] The traditional pressure relief device installed on the closed container can only achieve one-way pressure relief, which cannot meet the various needs of the closed container, and it is only a mechanical structure and cannot be remotely controlled

Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] Such as Figure 1-3 As shown, an intelligent pressure relief device of the present invention includes a base 1, a positive pressure valve cover 2, a negative pressure valve cover 3, and a spring 4; the positive pressure valve cover 2 is rotatably connected to one side of the base 1, and the positive pressure valve When the cover 2 is closed, the positive pressure bonnet 2 forms a sealing fit with the base 1; the negative pressure bonnet 3 is located inside the positive pressure bonnet 2 and is smaller than the positive pressure bonnet 2, and the negative pressure bonnet 3 is connected to the positive pressure through the middle spring 4. The bonnet 3 is conne...

Abstract

The invention discloses an intelligent pressure relief device. The intelligent pressure relief device comprises a base, a positive-pressure valve cover, a negative-pressure valve cover and a spring, wherein the positive-pressure valve cover is rotationally connected with one side of the base; when the positive-pressure valve cover is closed, the positive-pressure valve cover and the base are in sealing fit; the negative-pressure valve cover is positioned at the inner side of the positive-pressure valve cover, and is smaller than the positive-pressure valve cover; the negative-pressure valve cover is connected with the positive-pressure valve cover through the spring; a hole is formed in the positive-pressure valve cover; and when the negative-pressure valve cover is closed under the effect of spring force, the hole is covered. The intelligent pressure relief device can realize two-way pressure relief thereof through the fit between the positive-pressure valve cover and the negative-pressure valve cover through the spring and the like, and further comprises a control system to realize such functions as remote control, ventilation and pressure re-relief.

Description

technical field [0001] The invention relates to the field of pressure relief devices, in particular to an intelligent pressure relief device. Background technique [0002] The closed container storing combustible materials sometimes causes the instantaneous pressure to rise rapidly due to the uncontrolled deflagration of the internal materials, which exceeds the capacity of the system. In order to protect the system from being damaged, it is necessary to quickly release the pressure from the designated position to the designated direction. [0003] In a closed container with negative pressure operation, sometimes due to system failure, the inlet end cannot be effectively fed in and the outlet end is always working, resulting in a gradual decrease in system pressure, which even exceeds the system’s capacity. Add gas inside, that is, release pressure inward to balance the internal and external pressure difference. [0004] Due to technological requirements, the closed contain...
