Abstract
The utility model discloses a seal ring of a mortar pump. The seal ring of the mortar pump comprises an annular body (1). The upper edge of the outer ring surface of the body (1) is provided with a bulge (2) along the radial direction; an included angle alpha is formed between the outer surface of the bulge and the outer ring surface of the body; the included angle alpha is 120-178 degrees; and an annular groove (3) is arranged at the position of the included angle. The seal ring of the mortar pump is better in sealing property when pressure is higher.
Description
Technical field
The utility model belongs to the Sealing field, particularly relates to a kind of mortar pump seal ring that is used for the mortar pump sealing.
Background technique
The mortar pump seal ring of existing technology is not prone to leakage phenomenon for when wearing and tearing is arranged at outer ring surface; Top edge at the outer ring surface of mortar pump ring body is provided with convexity radially; The outer surface of described convexity and body outer ring surface shape in an angle, described angle is 120 ° ~ 178 °.The shortcoming that existing technology exists is: but the mortar pump pressure leakage of a little still can occur when higher, and sealability is good inadequately.
The model utility content
The utility model technical problem to be solved is, provide a kind of when pressure is higher the mortar pump seal ring of good seal performance.
The technological scheme of the utility model is; A kind of mortar pump seal ring with following structure is provided; It comprises the body of annular, and the top edge of described body outer ring surface is provided with convexity radially, and the outer surface of described convexity and body outer ring surface form an angle; Described angle is 120 ° ~ 178 °, and described angle is provided with annular groove.
After adopting said structure, the utility model mortar pump seal ring compared with prior art has the following advantages:
The utility model is because the outer surface middle and lower part of the convexity of the top edge of body outer ring surface is provided with groove; Liquid can get in the groove; When receiving elevated pressures; The mortar pump seal ring pressure of the utility model is also big, under pressure the mortar pump seal ring is close on the sealing surface, and sealability is better.
As a kind of improvement of the utility model, described groove cross section is triangle or circular arc, and the triangle or the circular groove of rule are made easily.
Description of drawings
Shown in Figure 1 is the structural representation of the utility model mortar pump seal ring.
Shown in Figure 2 for the groove cross section be the sectional structure schematic representation of leg-of-mutton embodiment along A-A among Fig. 1.
The sectional structure schematic representation that for the groove cross section is the embodiment of circular arc along A-A among Fig. 1 shown in Figure 3.
Shown in the figure: 1, body, 2, convexity, 3, groove.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Please with reference to Fig. 1, Fig. 2 and shown in Figure 3; It comprises the body 1 of annular the mortar pump seal ring of the utility model; The top edge of described body 1 outer ring surface is provided with convexity 2 radially; The outer surface of described convexity and body outer ring surface form an angle, and described angle is 120 ° ~ 178 °, it is characterized in that: described angle is provided with annular groove 3.
The cross section of described annular groove 3 is a triangle.
The cross section of described annular groove 3 is a circular arc.
Above embodiment is merely the preferred embodiment of the utility model; The utility model is not limited to above specific embodiment, also can do some and change, and changes the groove that is interrupted into like described annular groove 3; It is irregularly shaped etc. that described groove 3 is shaped as, all in the protection domain of the utility model.
