Description of the drawings:
FIG. 1 is a schematic perspective view of the present utility model;
FIG. 2 is a schematic cross-sectional view of the present utility model;
fig. 3 is a state of use diagram of the present utility model.
In the figure: 1. an outer annular body; 2. an inner annular body; 3. a skeleton; 4. a V-shaped lip portion; 5. an annular convex ring; 6. annular convex ribs; 7. a pump head; 8. and a plunger hole.
The specific embodiment is as follows:
the utility model is further described below with reference to the specific examples, see fig. 1-3:
the utility model provides a plunger pump water seal which comprises an outer annular body 1, an inner annular body 2 and a framework 3 with an L-shaped section, wherein the outer annular body 1 and the inner annular body 2 are coaxially arranged, the outer annular body 1 and the inner annular body 2 are of an integrated structure made of rubber materials, the upper end of the inner annular body 2 is lower than the outer annular body 1, and the upper ends of the outer annular body 1 and the inner annular body 2 are both plane surfaces. The lower ends of the outer annular body 1 and the inner annular body 2 are connected into a whole, and a V-shaped lip part 4 is formed at the upper end. The framework 3 comprises a vertical part and a horizontal part, the horizontal part is positioned at the lower end of the vertical part, the vertical part is positioned in the outer annular body 1, and the horizontal part extends to the lower end of the inner annular body 2.
The utility model is arranged in the plunger hole 8 of the pump head 7 of the plunger pump and sleeved on the plunger, and the skeleton 3 is arranged in the outer ring body 1 and the inner ring body 2, so that the water seal can be prevented from deforming in the axial direction and the radial direction, the strength of the water seal is greatly increased, the water seal is not easy to deform, the plunger pump is not easy to leak water finally, and the overall performance and the service life of the plunger pump are improved.
