Abstract
The utility model relates to a leak-proof structure of a filling valve. The leak-proof structure of the filling valve comprises a hollow valve body, a valve rod is arranged inside the valve body and a sealing element is arranged at the bottom of the valve rod. A material discharging port is arranged at the bottom of the valve body, and the sealing element is matched with the material discharging port. The bottom of the sealing element is of a circular-arc-shaped structure. A ring-shaped plate is arranged at the bottom of the valve body. A hole is formed in the center of the ring-shaped plate and matched with the material discharging port. A gap exists between the upper end face of the ring-shaped plate and the bottom of the valve body. Due to the fact that the bottom of the sealing element is of the circular-arc-shaped structure, a little material residual at the bottom of the sealing element can not gather into drips under the surface tension of the sealing element, and leaking is not caused. In addition, the ring-shaped plate is installed on the lower portion of the valve body, the gap exist between the ring-shaped plate and the lower wall of the valve body, and thus, the little material residual at the bottom of the valve body can not cause the leaking due to the siphon principle. Therefore, a bottle mouth can not be polluted.
Description
Technical field
The utility model relates to the technical field of structures of filling valve, refers to a kind of leakage-proof structure of filling valve especially.
Background technique
The structure of filling valve generally includes a hollow valve body, and valve inner is provided with valve rod, and the bottom of valve rod is provided with Sealing, and the top of valve body is provided with supply pipe, and the bottom of valve body is discharge port, and Sealing matches with discharge port.During original state, Sealing and discharge port are inconsistent, realize the sealing of discharge port, and material enters valve inner through supply pipe, the valve that moves up out along with valve rod, Sealing and discharge port break away from, and final quantitative material flows out from discharge port, realizes can, after expendable is finished, valve rod moves down the pass valve, and Sealing and discharge port are fitted again, realizes sealing.The structure of present employed Sealing and valve body as shown in Figure 3, the tapered structure in the bottom of Sealing 1, after closing valve, also a small amount of material 3 can residually be arranged on Sealing 1 and the Sealing valve body 2 below 1, material 3 down accumulates along Sealing 1 and discharge port 4 and drips, cause water clock, may pollute bottleneck.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of and material can not accumulated drip, cause the leakage-proof structure of the filling valve of water clock.
For addressing the above problem, the technical solution adopted in the utility model is: the leakage-proof structure of filling valve, comprise a hollow valve body, valve inner is provided with valve rod, and the bottom of valve rod is provided with Sealing, the bottom of valve body is discharge port, Sealing matches with discharge port, and the bottom of described Sealing is arc-shaped structure, and the bottom of valve body is provided with annular slab, the center of annular slab is provided with the hole of matching with discharge port, has the gap between the upper-end surface of annular slab and the bottom of valve body.
Be tightly connected between the periphery of described annular slab and the valve body bottom.
Be embedded with seal ring in the periphery upper wall of described annular slab, the diapire of seal ring and valve body is inconsistent.
The diapire of described valve body is provided with the valve body step, is provided with the annular slab step that matches with valve body in the upper wall of described annular slab.
The bottom of described valve body is provided with connecting cover, and the center of connecting cover is provided with the lid hole of matching with discharge port, and connecting cover is threaded mutually with the outside of valve body, and described annular slab is arranged between connecting cover and the valve body bottom.
The beneficial effects of the utility model are: the leakage-proof structure of above-mentioned filling valve, be arc-shaped structure by the bottom with Sealing, thereby make the residual a small amount of material in Sealing bottom cause water clock after dripping can not accumulating under the effect of seal surface tension force, in addition, by the bottom at valve body annular slab is installed, and there is the gap between the low wall of annular slab and valve body, make a small amount of material that remains in the valve body bottom can not cause water clock owing to siphon principle, and then avoided bottleneck is polluted.

Embodiment
Be described in further detail below by the leakage-proof structure of specific embodiment to filling valve described in the utility model.
As shown in Figure 1, the leakage-proof structure of filling valve, comprise a hollow valve body 2, valve body 2 inside are provided with valve rod 5, and the bottom of valve rod 5 is provided with Sealing 1, the bottom of valve body 2 is discharge port 4, Sealing 1 matches with discharge port 4, and the bottom of described Sealing 1 is arc-shaped structure, and the bottom of valve body 2 is provided with annular slab 6, the center of annular slab 6 is provided with the hole of matching with discharge port 4, has gap 7 between the bottom of the upper-end surface of annular slab 6 and valve body 2.Be embedded with seal ring 8 in the periphery upper wall of described annular slab 6, seal ring 8 is inconsistent with the diapire of valve body 2, thereby is tightly connected between the periphery of realization annular slab 6 and valve body 2 bottoms.In the present embodiment; mode by seal ring 8 realizes being tightly connected between the periphery of annular slab 6 and valve body 2 bottoms; wherein the periphery of annular slab 6 can be multiple different scheme with the structure that is tightly connected of valve body 2 bottoms, all belongs to protection category of the present utility model.
As preferred version, the diapire of described valve body 2 is provided with valve body step 21, is provided with the annular slab step 61 that matches with valve body 2 in the upper wall of described annular slab 6.Cooperate by step is set, make that the periphery of annular slab 6 and the structure that is tightly connected between valve body 2 bottoms are more reliable.
As preferred version, the bottom of described valve body 2 is provided with connecting cover 9, and the center of connecting cover 9 is provided with the lid hole of matching with discharge port 4, and connecting cover 9 is threaded mutually with the outside of valve body 2, and described annular slab 6 is arranged between connecting cover 9 and valve body 2 bottoms.Mode by connecting cover 9 is arranged on valve body 2 bottoms with annular slab 6, makes annular slab 6 conveniently to install, and cleans after can be for convenience detach.
