Problems solved by technology
[0004] The above patents add grid-like ribs to the expansion tank of the traditional structure. These ribs divide the interior of the expansion tank into multiple compartments connected by through holes, thus enhancing the overall strength of the expansion tank and overcoming the tank wall. Defects that are easily deformed, but the inventors have found that there are still certain problems in it. One is that the structure is too complicated, the manufacturing mold is difficult and the cost is high, and the other is that the expansion tank does not have a liquid replenishment port. Safety, so people are in urgent need of a simple structure, easy to manufacture, safe and reliable expansion tank

The invention discloses an automatic constant-pressure expansion tank for an automobile. The tank comprises a kettle body and a kettle cover, wherein the kettle body is formed by hermetically laminating upper and lower tank bodies and is in threaded connection with the kettle cover. The tank is characterized in that: the kettle body is provided with a liquid replenishing port capable of replenishing cooling liquid to a system at any time; and the kettle cover is provided with an adjusting device for keeping the constant pressure of the system. The tank has the characteristics of simple structure, high intensity, safety, reliability, wide applicability and the like.
Description
technical field [0001] The invention relates to an expansion water tank, in particular to an automatic constant-pressure expansion water tank for vehicles. Background technique [0002] The expansion tank is to contain and compensate the expansion and contraction of water in the system. When the engine is working, the temperature of the car's cooling system rises, and the coolant will expand. If the coolant vapor enters the expansion tank and flows back to the radiator after cooling, it can prevent a large amount of evaporation loss of the coolant and improve the cooling performance of the coolant. Boiling point temperature, at this time, the expansion water tank can eliminate the steam in the low-pressure part of the cooling system, so that it will not cause air resistance, and at the same time give the cooling water room for expansion due to changes in temperature, load, and speed to ensure the circulation capacity of the cooling water. If there is no expansion If the wat...
