Abstract
The invention discloses an automobile expansion box, comprising a main expansion box and a secondary expansion box. A pressure box is arranged on the main expansion box; a pressure vacuum combined valve is arranged on a gas-liquid path formed between the main expansion box and the second expansion box, and a cover cavity of the pressure cover; and when a pressure valve opening of the pressure vacuum combined valve is opened, a cooling liquid flows to the secondary expansion box from the main expansion box, and when a vacuum valve opening of the pressure vacuum combined valve is opened, a cooling liquid flows from the secondary expansion box to the main expansion box. A pressure cover of a cooling system covers on the main expansion box; the secondary expansion box is used for recovering a cooling liquid-gas mixture overflowing when a pressure valve is opened; and the internal cooling liquid flows back to the main expansion box when a vacuum valve is opened under the atmospheric pressure. Accordingly, the automobile expansion box provided by the invention can effectively recover the overflowed cooling liquid-gas mixture, so that when the cooling system is short of the cooling liquid, the recovered cooling liquid can be conveniently re-injected to the main expansion box by opening the vacuum valve.
Description
Technical field
Patent of the present invention relates to a kind of automobile expansion tank.
Background technique
The pressure cover (comprising pressure valve and vacuum valve) of full cut-off formula cooling system all places on the expansion tank now.When pressure cover placed on the expansion tank, in order to be beneficial to system's degasification, the height of expansion tank should be designed to the highest point of system.Pressure valve cracking pressure operated by rotary motion gets higher (with respect to the pressure cover cracking pressure that is arranged on the radiator), can improve the radiating efficiency of cooling system like this.And pressure cover place and pump front position are nearer, and the pressure loss is less, and pressure is bigger before the pump, and anti-cavitation erosion ability is stronger.But the cooling liquid vapour mixture that when pressure valve is opened, overflows is scattering in the atmosphere environment mostly, has both caused the waste of cooling liquid, again environment has been caused pollution.When vacuum valve is opened, mend into system for atmosphere mostly, cooling liquid does not obtain in time replenishing.
In addition, add inject cooling liquid when backing out pressure cover, when pressure cover is placed on one side, be prone to roll fall to the ground or engine compartment in, damage (especially regional at microthermal climate) is fallen in easy generation, also can be infected with foreign material such as dust, greasy dirt.If fall into the slit of component in the engine compartment, be difficult to seek and take out.
Summary of the invention
The object of the invention just provides cooling liquid vapour mixture that a kind of recovery overflows, makes things convenient for the expansion tank of supply cooling liquid simultaneously again.
For realizing above-mentioned purpose; The present invention has adopted following technological scheme: the automobile expansion tank; It is characterized in that: expansion tank comprises main expansion tank, secondary expansion tank; On the main expansion tank pressure cover is set; Constitute the gas-liquid path between the lid chamber of main expansion tank, secondary expansion tank and pressure cover and be provided with the pressure vacuum combination brake switch and proporting, the autonomous mutually expansion tank of gas-liquid flowed to secondary expansion tank when the pressure valve port of pressure vacuum combination brake switch and proporting was opened, and cooling liquid flowed to main expansion tank from secondary expansion tank when the vacuum valve port of pressure vacuum combination brake switch and proporting was opened.
Can know by technique scheme, expansion tank assembly inside is separated, be divided into main expansion tank and secondary expansion tank.The pressure cover of cooling system places on the main expansion tank.The cooling liquid vapour mixture that secondary expansion tank overflows when being used for the pressure recovery opening of valves, and vacuum valve when opening with internal coolant counter refilling in the main expansion tank under atmospheric pressure.Therefore, the present invention can effectively reclaim the cooling liquid vapour mixture that overflows, and when cooling system lacks cooling liquid, can utilize vacuum valve to open the cooling liquid that will reclaim easily and be filled into again in the main expansion tank.
