Description
[technical field]
The utility model relates to field of automobile, particularly a kind of expansion tank used for automobile.
[background technique]
Expansion tank used for automobile mainly is contained in the refrigeration system, is used for regulating the interior water yield of engine water tank, prevents that refrigeration system from entering air and improving engine water pump water inlet static pressure to avoid producing cavitation erosion.Existing expansion tank used for automobile material category is a lot, but its complex structure, manufacture cost are higher, installs inconveniently, uses also inconvenient.
[summary of the invention]
In order to solve existing expansion tank complex structure, manufacture cost height and to install, use all technical problems of inconvenience, the utility model provides a kind of expansion tank used for automobile simple in structure, easy to loading and unloading.
The technological scheme that the existing technical problem that solves the utility model adopts is: a kind of expansion tank used for automobile, it comprises the drain connecting tube 5 that is used to hold the casing 1 of cooling liquid and is used for water conservancy diversion, but described drain connecting tube 5 bidirectional guide; Described expansion tank 100 also comprises an air guide connecting tube 6.
The utility model further improves, and comprises a dismountable case lid 3.
The utility model further improves, and described drain connecting tube 5 or described air guide connecting tube 6 are installed on the described case lid 3.
The utility model further improves, comprise that one is arranged on the conduit 4 of described casing 1 inside, this conduit 4 was communicated with described drain connecting tube 5, was used for cooling liquid is flowed in the described casing 1 through described drain connecting tube 5 from described 1 interior introducing described drain connecting tube 5 of casing or with cooling liquid.
The utility model further improves, and comprises a pipeline 2, and this pipeline 2 was communicated with described drain connecting tube 5, is used for described expansion tank 100 and engine-cooling system conducting.
The utility model further improves, and described pipeline 2 is a sebific duct.
The utility model further improves, and described casing 1 comprises inserting groove 7, is used to install described expansion tank 100.
Compared to prior art, usefulness of the present utility model is: simple in structure, easily manufactured, simultaneously, drain connecting tube is a bidirectional guide, cooling liquid in the expansion tank does not participate in the circulation of engine-cooling system substantially like this, improves the working life of expansion tank and cooling liquid thereof; In addition, air guide connecting tube is used to regulate the air pressure of expansion tank, indirect adjusting the pressure of engine-cooling system, reduced the sealing requirements of whole system like this; The fault freedom of system is good, when expansion tank breaks down, can not influence the normal operation of engine-cooling system in the short time; Expansion tank is provided with inserting groove, and spile type is installed expansion tank, and structure is simpler, and dismounting is very convenient.

[embodiment]
Below in conjunction with description of drawings and embodiment the utility model is further specified.
As shown in Figures 1 to 4.A kind of expansion tank used for automobile 100, it comprises the drain connecting tube 5 that is used to hold the casing 1 of cooling liquid and is used for water conservancy diversion, but described drain connecting tube 5 bidirectional guide; Described expansion tank 100 also comprises an air guide connecting tube 6.
The utility model one preferred embodiment is, comprises a dismountable case lid 3, and drain connecting tube 5 or air guide connecting tube 6 are installed on this case lid 3.Expansion tank 100 comprises that also one is arranged on the conduit 4 of casing 1 inside, and this conduit 4 was communicated with drain connecting tube 5, is used for cooling liquid is flowed in the casing 1 through drain connecting tube 5 from 1 interior introducing drain connecting tube 5 of casing or with cooling liquid; One pipeline 2, this pipeline can be sebific duct, is communicated with drain connecting tube 5, is used for expansion tank 100 and engine-cooling system mutual conduction.
The utility model one preferred embodiment is, casing 1 comprises inserting groove 7, and the plate of relevant position matches on this inserting groove and the automobile, is used to install expansion tank 100.Easy accessibility, installation are stablized.
The working principle of described expansion tank is, a certain amount of cooling liquid of deposit in the expansion tank, when the temperature decline of engine-cooling system, when internal system pressure reduces, cooling liquid is by conduit 4 upwards, drain connecting tube 5 and pipeline 2 through on the case lid 3 flow in the engine-cooling system.When the pressure that produces owing to being heated when engine-cooling system was excessive, steam or cooling liquid can be got back to expansion tank by opposite path, reach the effect of balance sysmte pressure.Be communicated with simultaneously air and extraneous atmosphere in the expansion tank air guide connecting tube 6, be used to regulate the pressure that changes owing to the engine-cooling system effect in the expansion tank.
Expansion tank of the present utility model is simple in structure, easily manufactured, and simultaneously, drain connecting tube is a bidirectional guide, and the cooling liquid in the expansion tank does not participate in the circulation of engine-cooling system substantially like this, improves the working life of expansion tank and cooling liquid thereof; In addition, air guide connecting tube is used to regulate the air pressure of expansion tank, indirect adjusting the pressure of engine-cooling system, reduced the sealing requirements of whole system like this; The fault freedom of system is good, when expansion tank breaks down, can not influence the normal operation of engine-cooling system in the short time; Expansion tank is provided with inserting groove, and spile type is installed expansion tank, and structure is simpler, and dismounting is very convenient.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
