Problems solved by technology
Through the analysis of the existing known technology and the actual application, it can be seen that due to the brittleness of the glass and the uncontrollable strength and depth accuracy of the scratched glass, the rate of breakage of the sealing components of the air bubble generator during the movement, transportation and installation process is quite high. High, reaching more than 30%
[0005] The explosion panel that uses glass as a sealed component is also strictly limited in terms of the temperature of the storage and use environment. Generally, it can only be used in the range of normal temperature 0°C to 50°C. If it exceeds this range, the sealing and reliability of the glass will be greatly reduced.
For some special occasions where the ambient temperature reaches or exceeds 100°C, it cannot be used at all
The above-mentioned defects in the prior art have seriously hindered the popularization and development of the air foam generator in the field of fire protection

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as Figure 1 to Figure 4 As shown, an air foam generator with a highly reliable sealing assembly has a body 1, a sealing assembly 2, a shroud 4 and a cover plate 5, and the generator body 1 and the sealing assembly 2 pass through the bolt assembly and the pressure plate sealing ring 8 Sealed connection, the shroud 4 is sealed connected with the body 1 through the connecting flange assembly 3, the cover plate 5 is sealed connected with the cover sealing ring 6 through the bolt assembly 7, and the sealing assembly 2 of the vertical foam generator Set with a bursting disc.
[0026] The burst disc is set as a metal diaphragm 11 . The thickness of the metal diaphragm 11 is 0.01mm-0.02mm. The burst value of the metal diaphragm 11 is between 0.1 MPa and 0.3 MPa.
[0027] The sealing assembly includes a lower pressing plate 9 , a sealing ring 10 , a metal diaph...

Abstract
The present invention discloses a vertical foam generator, which comprises a body, a sealing assembly, a diversion shield and a cover plate, wherein the body and the sealing assembly form a sealed connection through a bolt assembly and a plate pressing sealing ring, the diversion shield and the body form a sealed connection through a connection flange assembly, and the cover plate and a cover sealing ring form a sealed connection through a bolt assembly. The vertical foam generator is characterized in that the sealing assembly of the vertical foam generator is provided with a blasting sheet, the blasting sheet is arranged into the metal diaphragm, the thickness of the metal diaphragm is 0.01-0.02 mm, the blasting value of the metal diaphragm is 0.1-0.3 MPa, the materials of the plate pressing sealing ring and the cover sealing ring are the high temperature resistance rubber materials, and the suitable environment temperature of the high temperature resistance rubber material is 200 DEG C. According to the invention, with the optimized design on the blasting sheet and the sealing ring, the error blasting phenomenon of the air foam generator during the moving, transportation and installation processes can not occur, and the air foam generator can be stored and used under the environment with the temperature of 200 DEG C.
Description
technical field [0001] The invention relates to the technical field of fire protection, in particular to a vertical foam generator. Background technique [0002] The foam generator is a kind of fire extinguishing equipment fixedly installed on the oil tank to generate and spray air foam. When the foam fire truck is fixed on the foam mixed liquid flow given by the fire pump, when it passes through the generator through the delivery pipeline, air foam is formed to extinguish oil fires. The working principle of the vertical foam generator is to mix the foam mixture produced by the proportional mixing device with the inhaled air, foam to generate foam, and spray the foam to the surface of the burning liquid to form a foam layer to insulate air and absorb heat, and finally put Fire extinguishing device. [0003] The sealing assembly is a key component of the vertical foam generator. During normal operation, the sealing components need to maintain good sealing performance under...
