Constant volume bomb window

Abstract

The invention aims to provide a constant volume bomb window with a glass window protection structure to solve the problems of uneven stress and bumping damage to a traditional volume bomb glass window. When the constant volume bomb window is impacted, impact force can be effectively buffered, and volume bomb sealing is ensured. The constant volume bomb window comprises a constant volume bomb body, a circular glass window, an O-shaped sealing ring, a first metal washer, a second metal washer, a pressing plate, bolts and nuts, the first metal washer and the second metal washer are the same in structure and positioned on two sides of the glass window respectively, annular bosses are arranged at the edges of the first metal washer and the second metal washer and face one side of the glass window, bolt holes are formed in the periphery of the pressing plate, one end of the bolt is fixed to the constant volume bomb body, and the other end of the bolt penetrates the bolt hole of the pressing plate and is connected with the nut, so that the O-shaped sealing ring, the first metal washer, the glass window, the second metal washer are fixedly compressed between the constant volume bomb body and the pressing plate.

Description

technical field [0001] The invention belongs to the technical field of engine design and testing, and in particular relates to a constant-volume bomb window in the field of engine fuel injector spray research. Background technique [0002] At present, most of the glass windows of constant-volume bombs do not have a glass window protection structure. During the installation and disassembly process, there will be uneven force and bumps on the glass, which will cause damage to the glass window, affect the mechanical properties of the glass window, and cause the glass window to break. Crack or constant volume bomb leakage. Constant-volume bombs need to be ventilated frequently during use, so that the constant-volume bombs will be impacted by internal and external pressure. However, most of the current constant-volume bombs use a first-level seal. It is difficult to ensure that the constant-volume bomb windows can buffer the impact of the volume bomb. While ensuring sealing. C...

Problems solved by technology

[0005] When the constant volume bomb is impacted by pressure, the O-ring can effectively buffer and solve the problem that the gasket seal cannot be used under high sealing pressure, but at the same time, a large stress concentration will be formed in the O-ring seal, directly It is not feasible to use it on the glass window. In the present invention, the use of two metal gaskets can effectively solve this problem. The stress formed by the O-shaped sealing ring can be evenly transmitted to the glass window through the metal gasket, which effectively protects the glass window safety
