Description
Technical field
The utility model relates to expansion tank technical field, in particular to a kind of expansion water tank for automobile.
Background technique
Existing expansion tank is primarily present following deficiency:
(1) water tank occupies larger space, and tank wall is thicker.
(2) filling lid, decompression cover are arranged in high-order above water tank, and occupied space is larger.
(3) copper formula sensor, built-in structure are directly contacted with anti-icing fluid, and there are the risks of leakage.
(4) thread seal mode is used, water tank leakage is easily led to.
Summary of the invention
In order to solve problems in the prior art, the utility model provides the vapour that a kind of structure is simple, avoids leakage risk
Vehicle expansion tank.
Technical solution described in the utility model is as follows:
A kind of expansion water tank for automobile, including the tank body being welded by upper box and lower box, the water tank sheet
It is equipped with fluid chamber and siphon chamber in vivo, is equipped in the first groove of the upper box side above the fluid chamber and removes port, institute
It is equipped with filling opening in the second groove of side except port stated, in the third groove on the opposite side upper box except port
Equipped with card slot, water level sensor is configured in the card slot, below the fluid chamber of the fluid chamber and siphon chamber intersection
Lower box is equipped with water supplement port, and the upper box side above the siphon chamber is equipped with pressure relief opening, the fluid chamber and siphon
Chamber boundary is equipped with siphon passage, air inlet in the siphon passage, and the air inlet opposite side is equipped with backwater hole.
The filling opening is equipped with liquid feeding lid.
The pressure relief opening is equipped with decompression cover.
The two sides of the lower box are equipped with mounting base, open up mounting hole in the mounting base.
Technical solution provided by the utility model has the benefit that
It is arranged in side by filling lid, decompression cover, same volume condition lower header, which integrally takes up space, to become smaller, filling
Lid, decompression cover are located in groove, are reserved and are screwed subspace of uncapping by hand.Water level sensor clamping assembly external, with water tank
It is internal non-contact, the risk of leakage is avoided from source, using clamping assembly method, repetition is facilitated to dismount.Fluid chamber and rainbow
The setting for inhaling chamber facilitates and realizes entire cooling system internal and external pressure balance.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model siphon chamber internal view.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figs. 1-2, a kind of expansion water tank for automobile, including the water tank sheet being welded by upper box 1 and lower box 2
Body, the tank body is interior to be equipped with fluid chamber and siphon chamber, the first groove of 1 side of upper box above the fluid chamber
It is equipped in 8 and removes port 3, equipped with filling opening in second groove of side 9 except port 3, the described opposite side except port 3
It is equipped with card slot in third groove 12 on upper box 1, configures water level sensor 7, the fluid chamber and rainbow in the card slot
It inhales the lower box 2 below the fluid chamber of chamber intersection and is equipped with water supplement port 6,1 side of upper box above the siphon chamber is set
There is pressure relief opening, the fluid chamber and siphon chamber boundary are equipped with siphon passage, and air inlet 10 in the siphon passage is described
Air inlet opposite side be equipped with backwater hole 11.
The filling opening is equipped with liquid feeding lid 4.
The pressure relief opening is equipped with decompression cover 5.
The two sides of the lower box 1 are equipped with mounting base 13, open up mounting hole in the mounting base 13.
Gas liquid mixture in engine-cooling system, by entering inside fluid chamber except port 3, with pressure in fluid chamber
When power increases, liquid intracavity gas enters siphon chamber by air inlet 10 in siphon passage, is let out when reaching positive pressure value by opening
5 pressure release of gland.After engine stop work, negative pressure is generated in cooling system, after reaching negative pressure value, atmospheric pressure enters siphon chamber,
A small amount of liquid refills fluid chamber by backwater hole 11 in siphon passage, realizes entire cooling system internal and external pressure balance.
Liquid feeding lid 4 is arranged in 1 upper side position of upper box, avoids the high-order inadequate problem in screw thread space, in upper position
Design itself has and prevents filling it up with function,
Water level sensor 7 is installed in the card slot on upper box 1, non-contact with internal anti-icing fluid, avoids leakage risk.Together
When convenient disassembly, compact.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
