Problems solved by technology

Some shells may break into pieces or the pieces may fly around causing hazards
The shock wave is as harmful as the debris and can cause casualties to nearby personnel
3) Poisoning of toxic media
4) Combustion of combustible medium and hazards of secondary space explosion
Many of them are due to the fact that the working medium inside the pressure vessel is not clean, and a large amount of sediment or powdery adherents will be produced during operation, which will hinder the operation of the safety valve. Therefore, it is necessary to design a new type of pressure explosion-proof device.

Embodiment Construction

[0016] Such as figure 1 As shown, the main components of the present invention are arranged on the pressure vessel door panel 19, that is, the bolt on the hinge of the pressure vessel door is changed into an explosion bolt, and when the explosion bolt explodes, the pressure vessel door opens automatically to relieve pressure. The pressure vessel will not explode, which plays a role in protecting the pressure vessel. The present invention mainly consists of a pressure sensor and an explosion bolt, wherein the explosion bolt is composed of an explosive 2, a reserved groove 3, a pressure vessel hinge outer nut 4, an explosive replacement screw 5 and an electrified wire 6, wherein the explosion bolt on the outer side of the pressure vessel A ring-shaped reserved groove 3 is set to cause stress concentration, so that when the explosion is broken along the ring-shaped reserved groove 3, the reserved groove is arranged on the outside of the pressure vessel, so that when the explosion...

Abstract

The invention specifically relates to a sensor and an explosive bolt device on a pressure vessel gate. Main parts are arranged on a hinge of the pressure vessel gate. Major components are arranged on a hinge of the pressure vessel gate. A bolt on the hinge of the pressure vessel gate is changed into an explosive bolt. After the explosive bolt explodes, the pressure vessel gate opens automatically and plays the function of releasing pressure. The pressure vessel cannot explode. Therefore, the function of protecting the pressure vessel is realized. The invention mainly comprises the pressure sensor and the explosive bolt which comprises an explosive (2), a pre-reserved groove (3), a transposition explosive screw (5) and an electrifying conductor (6). A current-limiting resistance, a slide rheostat and a diaphragm (16) of the pressure sensor are arranged in the pressure sensor. The resistance valve can be regulated. Thus, different pressure values can be set to lead to the explosion of the explosive bolt. With the invention adopted, accidents due to the failure of a safety valve can be reduced. The explosive bolt is provided with the pre-reserved groove. Therefore, the volume of wreck is small when the explosive bolt is broken, and equipment around cannot be damaged.

Description

technical field [0001] The invention relates to a pressure vessel safety device, in particular to a sensor and an explosion bolt device on the pressure vessel door. Background technique [0002] Pressure vessels generally refer to containers used in industrial production to complete production processes such as reaction, heat transfer, mass transfer, separation, storage and transportation, and to withstand a certain pressure. Such as reaction vessels, heat exchange vessels, separation vessels and storage and transportation vessels. Due to the various needs of the production process, there are many types of pressure vessels, and the specific structures are also various. But their common feature is that they all have a shell of various shapes that can withstand a certain pressure. my country's "Interim Regulations on Boiler and Pressure Vessel Safety Supervision" defines pressure vessels as "various pressure vessels with a pressure above one gauge pressure". It is also clea...
