Description
Technical Field
The invention relates to the structural design of a ventilation device, in particular to a multifunctional ventilation device for a liquid storage container.
Background
For containers for storing oil or other liquids, it is necessary to install a ventilation device in order to reduce the influence of air pressure changes caused by temperature or height changes; however, current ventilators suffer from a number of drawbacks.
Taking a helicopter as an example, a fuel tank stores a proper amount of fuel, and supplies oil to an engine through a fuel pump and a pipeline; in order to adapt to the air pressure change caused by temperature and height change, the fuel tank is provided with a corresponding ventilation device so as to ensure that the air pressure in the fuel tank is equivalent to the external environment, and simultaneously, under the conditions of oiling, discharging oil and continuously supplying oil to an engine, the increase and decrease of the oil quantity is ensured not to form unfavorable pressure difference in the fuel tank.
In addition, since the oil tank is directly communicated with the outside through the ventilation device, certain protection measures are required to prevent the pollution of the fuel oil in the ventilation process. In general, the ventilation device of the helicopter fuel tank is arranged on the side wall of the helicopter body, and the ventilation port adopts metal plate drilling holes for ventilation and is overlapped with the helicopter body, so that ventilation and lightning protection functions are realized; and moreover, the top of the ventilation pipeline, which is communicated with the oil tank, of the ventilation device adopts an inverted U-shaped structure, and a cap-shaped water retaining cover is additionally arranged outside the ventilation port, so that a waterproof function is realized. However, in the practical application process, it is found that such a structure often cannot effectively prevent foreign matters such as water, dust and the like from entering, and under some conditions, icing and blocking are easy to occur.
In summary, most current venting devices similar to those used in helicopter fuel tanks suffer from at least one of the following disadvantages:
1) The simple inverted U-shaped structure can not completely prevent the entry of rainwater impact, and a cap-shaped cover is additionally arranged outside the machine body, so that the appearance is influenced, and the aerodynamic resistance is increased;
2) When flying in a dust area, the negative pressure formed by continuous oil supply can suck dust into the oil tank and continuously gather to pollute the fuel;
3) Living foreign matters such as small insects and ants can enter the oil tank through the small hole of the vent hole to pollute the fuel;
4) When the ice environment works, the exposed air ports are easily blocked by ice.
