Abstract
The utility model discloses a sealing element for a water pump. The sealing element for the water pump comprises a body (1) which is provided with a center hole. One end of the body (1) is provided with a ringlike boss (2). The other end of the body (1) is provided with a radial bulge loop (3) which stretches towards an axis. The cross section of the radial bulge loop (3) is in a semicircular shape. A ringlike groove (4) is formed in the inner side of the top surface of the radial bulge loop (3). The sealing element for the water pump has the advantages of being capable of improving sealing effect.
Description
Technical field
The utility model relates to a kind of sealing element for water pump.
Background technique
Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.A kind of sealing element for water pump is arranged at present, comprise the body that is provided with center hole, be provided with annular boss at an end of body, be provided with radial convex loop to Axis Extension at the other end of body.This radial convex loop can be embedded into after assembling in the groove on the axle, can increase sealing like this, also can increase axial limiting.But the Sealing of above this structure has the following disadvantages: because the end face of annular boss and the junction of body are the right angle, when the opening that is like this pump housing offseted, there was certain interval in the reason that can process, has reduced like this sealing effect.
The model utility content
The technical problems to be solved in the utility model is that a kind of sealing element for water pump that can improve sealing effect is provided.
The technical solution of the utility model is, a kind of sealing element for water pump with following structure is provided, comprises the body that is provided with center hole, an end of described body is provided with annular boss, the other end of described body is provided with the radial convex loop to Axis Extension, the cross section semicircular in shape of described radial convex loop; The inboard of the end face of described radial convex loop is provided with annular groove.
The cross section of the outer side wall of described annular groove is curved.
The degree of depth of described annular groove is 0.5mm.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the inboard of the end face of described radial convex loop is provided with annular groove, Sealing is encased in the opening of pump body end surface and when offseting like this, make radial convex loop and the direct junction of body avoid directly contacting with the end face of opening, make Sealing more can with the opening close-fitting of the pump housing, can improve sealing effect.
Description of drawings
Accompanying drawing is the structural representation of a kind of sealing element for water pump of the present utility model.
As shown in the figure: 1, body, 2, annular boss, 3, radial convex loop, 4, annular groove.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, a kind of sealing element for water pump of the present utility model comprises the body 1 that is provided with center hole, and an end of described body 1 is provided with annular boss 2, the other end of described body 1 is provided with the radial convex loop 3 to Axis Extension, the cross section semicircular in shape of described radial convex loop 3; The inboard of the end face of described radial convex loop 3 is provided with annular groove 4.
The cross section of the outer side wall of described annular groove 4 is curved.
The degree of depth of described annular groove 4 is 0.5mm.
Described radial convex loop 3 is made of one piece with body 1.
Claims (3)
