Example Embodiment

[0042] Example

[0043] This embodiment provides two vacuum power and hydraulic power air tightness testing devices, such as figure 1 As shown, it is mainly divided into supercharging system ( figure 1 ) And pumping system ( Picture 10 ), the pressurization system and the air extraction system are connected and installed on the support seat; the pressurization system is divided into a vacuum power system and a water pressure system. The vacuum power system and the water pressure system are composed of their common components and their individual components, and complete the work separately , Its core component is the vacuum chamber subsystem.

[0044] Vacuum chamber subsystem (such as Figure 4 , Figure 5 (Shown) is composed of O-shaped rubber sealing ring 1, force transmitting member A2, O-shaped rubber sealing ring 3, O-shaped rubber sealing ring 4, force transmitting member B5, O-shaped rubber sealing ring 6 and supporting member 7. The O-shaped rubber sealing ring 1 and the O...

Abstract

The invention discloses a two-section vacuum power and water pressure power airtightness testing device, and relates to the technical field of airtightness detection. The device mainly comprises a pressurization system and an exhausting system. The pressurization system and the exhausting system are connected and are mounted on a supporting seat. The pressurization system is divided into a vacuumpower system and a water pressure system. The vacuum power system and the water pressure system are formed by common components and respective independent components, and independently complete work.The two-section vacuum power and water pressure power airtightness testing device can overcome the defects that traditional pipeline sealing performance testing equipment is complex in structure and poor in design flexibility, can expand or reduce the testing capacity according to the magnitude of testing pressure, and is good in design flexibility. The two-section vacuum power and water pressurepower airtightness testing device is simple in structure, convenient to maintain and low in manufacturing cost, and the defects that the traditional pipeline sealing performance testing equipment is not suitable for being repaired and high in manufacturing cost can be overcome.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a two-section vacuum power and hydraulic power airtight test device used in the pipeline systems of aircraft lavatories and kitchens. Background technique [0002] The lavatories and galleys on the aircraft have their own water intake system and drainage system. The water intake system and drainage system are composed of multiple pipelines. Affected by the working environment of the aircraft, the pipelines must meet certain sealing requirements. Withstand a certain design water pressure and not leak. If the pipeline fails, water leakage will affect flight safety. In order to ensure flight safety, after the pipeline components of the system and drainage system are installed, these pipelines must be tested for tightness to verify the pressure resistance of these pipelines and ensure that the tightness of the pipelines meets the requirements. At present, the pipeline ti...
