Description

Technical Field

[0001] The invention relates to the technical field of breathing valves, in particular to a breathing valve inspection platform for a normal pressure tank truck. Background Art

[0002] Tank trucks are transport vehicles with tank-shaped bodies, used to transport various liquids, liquefied gases and powdered goods, including gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various acidic and alkaline liquids, cement lead oxide powder, etc. Tank trucks occupy a very important position in transportation, accounting for about 18% of the total number of trucks. A breathing valve refers to a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but also communicates with the atmosphere (breathes) when the pressure exceeds or falls below this pressure range. Its function is to prevent the storage tank from being damaged due to overpressure or vacuum, and at the same time reduce the evaporation loss of the stored liquid. The installation of a breathing valve can not only reduce the emission of gas in the tank, thereby reducing pollution to the atmosphere, but also prevent the storage tank from being damaged due to overpressure or instability due to ultra-vacuum, which plays a certain role in promoting safety and environmental protection. The breathing valve is mainly composed of a valve seat, a valve cover, a protective cover and two sets of opening and closing devices controlled by vacuum and pressure;
