Embodiment Construction

[0033] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0034] According to an embodiment of the present application, refer to figure 1 , the altitude switch used in the aircraft wastewater system of this program, including:

[0035] The bouncing diaphragm 5, when operating, the bouncing diaphragm 5 overcomes the elastic force of the spring 15 and rebounds. At this time, the state of the switch base assembly 10 is switched, and the signal of the state switching is output through...

Abstract

The invention discloses a height switch for an aircraft wastewater system. The height switch comprises a bouncing diaphragm; the sensor combination comprises a pressure cavity which is arranged in a sealed mode, an isolation diaphragm is arranged in the pressure cavity, and the isolation diaphragm is freely connected with a bouncing diaphragm through a cover plate; the isolation diaphragm is used for converting the pressure changing along with the height into concentrated force and transmitting the concentrated force to the bouncing diaphragm, and the bouncing diaphragm bounces to drive the center rod to move. And one end of the switch seat combination is in signal connection with the socket, and the other end is in threaded connection with the sensor combination. In the using process, the pressure cavity senses pressure, the isolation diaphragm in the pressure cavity senses different pressure values along with different heights, the pressure values are transmitted to the bouncing diaphragm, then the center rod is driven to move, a height signal is converted into a displacement signal, then the signal is transmitted to the socket, and the socket is connected with the socket. And the displacement signal is converted into a switching value electric signal and is transmitted to an external system.

Description

technical field [0001] The invention belongs to the technical field of altitude switches for aircraft, and in particular relates to an altitude switch for aircraft waste water systems. Background technique [0002] At present, the height switches widely used in aviation, aerospace and related fields are mainly of metal diaphragm box type and corrugated diaphragm type structure, which mainly have two shortcomings: [0003] Insufficient corrosion resistance, because the water vapor mixture in the aircraft wastewater system is corrosive, which will corrode the metal diaphragm and diaphragm box in the altitude switch, limiting the service life of the altitude switch. [0004] The phenomenon of contact ablation, the height switch of the existing structure can be made into a smaller volume, but the closing and opening of the contacts is relatively slow, and sparks and arcs are easily generated, resulting in ablation of the pressure switch contacts. It is more obvious in the vibra...
