Abstract
The utility model discloses an expansion water tank cover for a vehicle, which belongs to vehicle parts. The utility model aims to provide the expansion water tank cover for the vehicle, which has stable property and a simple structure and is convenient to maintain. The expansion water tank cover comprises an outer cover, a valve cover and a breather valve, wherein a big breathing hole is formed at the top of the outer cover; the valve cover is fixed in the outer cover; the breather valve is arranged in the valve cover. The breather valve consists of a valve body (7), a valve core (6), a plug (5), a small spring (9) and a big spring (4), wherein the valve body (7) is arranged in the valve cover (2); the valve core (6) is arranged in the valve body (7); the plug (5) is arranged in the valve core (6); the small spring (9) is arranged in the valve body (7) and is tightly propped against the plug; the big spring (4) is arranged in the valve body (7) and tightly compresses the valve core (6); and a small breathing hole (10) is formed at the bottom of the valve body (7). The expansion water tank cover has the advantages of simple structure, small volume, light weight, convenience in maintenance, high reliability and the like, and is an ideal tank cover matched with the expansion water tank cover for the vehicle.
Description
Technical field: the utility model relates to a kind of water tank case lid, relates in particular to a kind of case lid that is used for the automobile swelling water tank.
Background technique: automobile-used swelling water tank case lid is a critical component of swelling water tank.When the cooling system lack of water, the pressure of system will reduce, and swelling water tank just can be by case lid to system water supplement; Otherwise when system pressure increased, system just can pass through the outside draining of case lid, thereby guaranteed the system pressure balance.At present, there are defectives such as poor reliability, maintenance difficult in the structure more complicated of automobile-used swelling water tank case lid.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of good reliability, simple in structure, the automobile-used swelling water tank case lid being convenient to keep in repair.
To achieve these goals, the utility model by the following technical solutions: it comprises that the top is provided with the enclosing cover of big spiracle, is fixed on valve gap in this enclosing cover, is located at the inhalation valve in this valve gap; Described inhalation valve is by being located at valve body in the valve gap, being located at spool in this valve body, being located at plug in this spool, being located at the little spring that in the valve body this plug held out against, being located at the big spring that in the valve body spool is compressed and constituting, and the bottom of valve body is provided with little spiracle.
Be provided with little sealing gasket between the bottom of spool and valve body, between the top of valve gap and valve body, be provided with big sealing gasket.
Compared with the prior art, the utility model has been owing to adopted technique scheme, therefore have simple in structure, volume is little, in light weight, easy to maintenance, reliable plurality of advantages such as good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: enclosing cover 1 valve gap 2 big sealing gasket 3 big springs 4 plugs 5 spools 6 valve bodies 7 little sealing gasket 8 little springs 9 little spiracle 10 big spiracles 11
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: the valve gap 2 that is provided with internal thread is fixed in the enclosing cover 1, is provided with inhalation valve in the valve gap 2; This inhalation valve is by being fixed on the valve body 7 that is tubbiness in the valve gap 2, being located at the spool 6 that is the convex sleeve-like structure in this valve body, being inserted in the plug 5 that is the convex structure in this spool, being located at the little spring 9 that in the valve body 7 this plug held out against, being located in the valve body 7 end and withstanding on the enclosing cover 1 the other end and withstand on the big spring 4 that on the spool 6 it is compressed and constitute.The top of enclosing cover 1 is provided with big spiracle 11, and the bottom of valve body 7 is provided with little spiracle 10.Tight in order to seal, between the bottom of spool 6 and valve body 7, be provided with little sealing gasket 8, between the top of valve gap 2 and valve body 7, be provided with big sealing gasket 3.
Working principle: when the cooling system lack of water, the pressure of system will reduce, and the water in the swelling water tank just can enter zone between valve body 7 and the spool 6 from little spiracle 10, back down then that spool 6 enters valve body 7 and by big spiracle 11 to system water supplement; Otherwise when system pressure was excessive, water in the system or gas just can enter valve body 7 by big spiracle 11, backed down plug 5 then and discharged from little spiracle 10, thereby guarantee the system pressure balance.
Claims (2)
1. automobile-used swelling water tank case lid comprises that the top is provided with the enclosing cover of big spiracle, is fixed on valve gap in this enclosing cover, is located at the inhalation valve in this valve gap; It is characterized in that: described inhalation valve is by being located at valve body (7) in the valve gap (2), being located at spool (6) in this valve body, being located at plug (5) in this spool, being located at the little spring (9) that in the valve body (7) this plug held out against, being located at the big spring (4) that in the valve body (7) spool (6) is compressed and constituting, and the bottom of valve body (7) is provided with little spiracle (10).
