The specific embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of solar water heater tank seal foaming bung, there is cock body 6, described cock body 6 can play sealing function for filling in the round of water tank, in order to express easily, claim that the direction that cock body 6 is filled in round is the place ahead (front end or front side) in the application, the direction of extracting round is rear (rear end or rear side), the orientation statement of other parts is also identical, wherein:
Described cock body 6 outside, rear end covers have 7, one baffle plates 8 of body seal circle to be bolted on described cock body 6 rear ends, and the axial location of described body seal circle 7 is limited, and described baffle plate 8 rear sides are fixedly connected with jug 10;
In described cock body 6, be equipped with vertically drive rod 4, on described drive rod 4, be formed with convex shoulder 41, at described convex shoulder 41 place's covers, there is sealing ring 3, described cock body 6 is formed with limiting stand 61 corresponding to described convex shoulder 41, when described drive rod 4 moves toward rear end, described convex shoulder 41 and the described sealing ring 3 of described limiting stand 61 extruding, can make to form airtight effect between described cock body 6 inside and outside.On described drive rod 4, be also coated with spring 5, the two ends of described spring 5 are against between described drive rod 4 and described baffle plate 8.
