Abstract

The invention discloses a butt joint for an aircraft vacuum waste water system and a ground sewage discharge vehicle, which is characterized in that it comprises a sewage joint and a heating pad, and adopts a double sealing structure, which has both an outer cover and an inner cover to ensure that the Reliability of sealing; simple and convenient operation, and low operating force; with heating function, it can be used normally even in low temperature environment. Compared with the traditional technology, the present invention has the characteristics of convenient and fast operation, high reliability, small operating force, long life, etc., so it can be widely used in low-pressure and large-flow (diameter) conduits in aircraft fuel, environmental control and water / wastewater systems It can be further extended to industries and fields such as aerospace, combat vehicles, ships and chemicals.

Description

technical field [0001] The application of the present invention belongs to a new type of sealing and opening technology, relates to the improvement of pipeline sealing and opening methods, and belongs to the field of aviation technology. Background technique [0002] The water / waste water system of aircraft, especially transport aircraft, passenger aircraft, etc. is connected to the ground sewage vehicle, and plays an indispensable role in the sewage joint. Due to the large diameter of the pipeline, ordinary joints are relatively bulky, inconvenient to install, especially inconvenient to operate, poor in reliability, prone to leakage, and are greatly affected by the environment and cannot work at low temperatures. Contents of the invention [0003] The purpose of the present invention is to provide a sewage discharge joint with reliable sealing, easy operation, small operating force, heating function, ensuring that the sewage is always above 0°C, and can be discharged smoo...
