Fig. 1 is a schematic structural view of the present invention.
FIG. 2 is a cross-sectional view of a siphon chamber of the present invention.
Fig. 3 is a partial cross-sectional view of the interior of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, an expansion tank for an automobile comprises a tank body welded by an upper tank body 1 and a lower tank body 2, wherein an upper liquid cavity and a lower siphon cavity are arranged in the tank body, a liquid filling opening is arranged on the side surface of the upper tank body 1 above the liquid cavity, a degassing opening 3 is arranged in a groove 8 on one side of the liquid filling opening, a clamping groove is arranged on one side of the degassing opening 3, a water level sensor 6 is arranged in the clamping groove, a pressure relief opening is arranged on the upper tank body 1 above the siphon cavity, a water replenishing opening 7 is arranged on the side surface of the upper tank body 1 above the siphon cavity, a siphon channel is arranged at the boundary of the liquid cavity and the siphon cavity, a water return opening 11 is arranged below the siphon channel, an air inlet 10 is arranged on the opposite side of the water return opening 11, a baffle 12 is arranged in the liquid cavity, and the baffle is arranged to ensure that a float 13 vertically, And the alarm is more accurate when the alarm is lowered.
And a liquid adding cover 4 is arranged on the liquid adding port.
And a pressure relief cover 5 is arranged on the pressure relief opening.
The water tank body below be equipped with mount pad 9 and supplementary mount pad, mount pad 9 and supplementary mount pad on all be equipped with the mounting hole.
The gas-liquid mixture in the engine cooling system enters the liquid cavity through the degassing port 3, when the pressure in the liquid cavity rises, gas in the liquid cavity enters the siphon cavity through the air inlet 10 above the siphon channel, and the pressure is relieved through the pressure relief port 5 when the positive pressure value is reached. After the engine stops working, negative pressure is generated in the cooling system, after the negative pressure value is reached, atmospheric pressure enters the siphon cavity, a small amount of liquid is replenished to the liquid cavity through the water return port 11 below the siphon channel, and the balance of the internal pressure and the external pressure of the whole cooling system is realized.
The lowest water level line of the water tank body is always higher than the radiator, and after the engine stops working, liquid in the liquid cavity can be smoothly supplemented back into the cooling system.
The water level sensor 6 is arranged in a clamping groove on the upper surface of the upper box body 1 and is in non-contact with the inner anti-freezing liquid, so that the risk of liquid leakage is avoided. Meanwhile, the dismounting is convenient, and the size is small.
