Description

Technical Field

[0001] The utility model relates to the relevant field of sealing rings, in particular to a valve core water leakage-proof sealing ring with uniform force. Background Art

[0002] In sanitary ware, the valve core is the core component of faucets, showers and other equipment. It plays a vital role. It has the functions of control, water saving and energy saving, and water temperature adjustment. A sealing ring is usually provided at the water inlet of the valve core. The valve core controls and adjusts the working state of the sanitary ware to ensure normal use. It is also related to the water-saving performance and service life of the product. It can block the flow of water when the sanitary ware is closed, prevent internal water leakage and external water entry, and ensure the sealing performance of the sanitary ware. It is an important component in the valve core.

[0003] The two ends of the sealing ring in the existing valve core usually adopt a flat design. When there is medium in the pipeline after the sanitary ware is closed, the medium will generate axial or radial thrust on the sealing ring. The force point of the flat-designed sealing ring that is subjected to the thrust is the contact point with the medium, which may easily cause uneven force on the sealing ring, easily affect the sealing performance of the sealing ring, cause medium leakage, and reduce the practicality of the sealing ring. Summary of the invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a valve core anti-leakage sealing ring with uniform force to solve the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a valve core anti-leakage sealing ring with uniform force, including a valve core body and a water inlet opened on the valve core body, the water inlet has a sealing ring body built in, and the sealing ring body is provided with arc surfaces at both ends.

[0006] Preferably, a receiving groove is provided along the circumferential side surface of the sealing ring body, and an arc-shaped top plate is arranged in the receiving groove.

[0007] Preferably, a notch is provided on the arc-shaped top sheet.

[0008] Preferably, the arc-shaped top sheet is an outwardly protruding structure, and the upper and lower ends of the outer side of the arc-shaped top sheet are connected to the side surface of the sealing ring body.

[0009] Preferably, two receiving grooves are arranged parallel to each other on the side surface of the sealing ring body, and an arc-shaped top sheet is arranged in each receiving groove.

[0010] Preferably, the sealing ring body protrudes outwardly in the circumferential direction at one end away from the water inlet to form a convex eave, and a buckle is provided at the edge of the convex eave facing one end of the valve core body.

[0011] Preferably, an arcuate surface is provided on the convex eave, and the arcuate surface on the convex eave is integrally formed with the arcuate surface on the sealing ring body.

[0012] Beneficial effects of the utility model:

[0013] The utility model arranges an arcuate surface on the sealing ring body and changes the plane of the sealing ring body into an arcuate surface. When the sanitary ware is closed, the force point of the sealing ring body on the medium is at the center of the arcuate surface, and the force is more uniform. The sealing performance of the valve core can be effectively improved, and leakage of the medium can be better prevented, thereby improving the practicability of the sealing ring.

[0020] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, the utility model provides a valve core water leakage prevention sealing ring with uniform force, comprising a valve core body 1 and a water inlet 2 provided on the valve core body 1, a sealing ring body 31 tightly extends into the water inlet 2, and arc surfaces 32 are provided at both ends of the sealing ring body 31;

[0023] In practice, the valve core body 1 is installed in a designated component in the sanitary ware, and the water inlet 2 is connected to the external high end. When the sanitary ware is closed, due to the provision of the arc surface 32, the force point of the sealing ring body 31 is at the center of the arc surface, and the force is more uniform, which can effectively improve the sealing of the valve core and better prevent medium leakage.

[0024] Example 2

[0025] like Figure 4 As shown, the utility model provides a valve core water leakage prevention sealing ring with uniform force. The sealing ring body 31 in this embodiment is provided with a receiving groove 33 along the circumferential side surface, and an arc-shaped top sheet 34 is provided in the receiving groove 33;

[0026] A notch is provided on the arc-shaped top sheet 34 to facilitate the elastic deformation of adjacent arc-shaped top sheets 34 simultaneously, so that the arc-shaped top sheets 34 can be stably received in the receiving groove 33;

[0027] The arc-shaped top sheet 34 is an outwardly protruding structure, and the upper and lower ends of the outer side of the arc-shaped top sheet 34 are connected to the side surface of the sealing ring body 31, so that the arc-shaped top sheet 34 can support the inner side wall of the water inlet 2, thereby improving the stability of the sealing ring body 31;

[0028] In this embodiment, two receiving grooves 33 are arranged parallel to each other on the side surface of the sealing ring body 31, and an arc-shaped top sheet 34 is arranged in each receiving groove 33, so that the stability of the sealing ring body 31 is improved by the two arc-shaped top sheets 34;

[0029] In this embodiment, the arc-shaped top sheet 34 is made of silicone material, so that the arc-shaped top sheet 34 can be contracted in the receiving groove 33 under pressure;

[0030] When the sealing ring body 31 in this embodiment is placed, the arc-shaped top sheet 34 is subjected to the pressure of the water inlet 2 and shrinks inward into the receiving groove 33. When the arc-shaped top sheet 34 enters the inner side of the water inlet 2, the arc-shaped top sheet 34 is tightly attached to the inner wall of the water inlet 2 due to its own elastic force, thereby providing auxiliary support for the sealing ring body 31, improving the stability of the sealing ring body 31, and providing a more stable seal for the valve core.

[0031] Example 3

[0032] like Figure 5 As shown, the utility model provides a valve core water leakage prevention sealing ring with uniform force. In this embodiment, the sealing ring body 31 is protruded outward along the circumferential direction at one end away from the water inlet 2 to form a convex eave 35. The edge of the convex eave 35 facing the end of the valve core body 1 is an integrated structure with a ring-shaped buckle ring 36;

[0033] The convex eave 35 is provided with an arc surface 32, and the arc surface 32 on the convex eave 35 is integrally formed with the arc surface 32 on the sealing ring body 31, so that the convex eave 35 and the arc surface 32 on the sealing ring body 31 are synchronously and evenly subjected to the force of the external medium;

[0034] In this embodiment, the convex eaves 35 provide positioning for the sealing ring body 31, so that the sealing ring body 31 can be installed stably, and can also provide auxiliary sealing for the sealing ring body 31 and the water inlet 1, thereby improving the sealing performance of the sealing ring body 31 connected to the water inlet 2 and reducing medium leakage. In addition, a convex body that cooperates with the buckle 36 can be provided on the valve core body 1, so that the buckle 36 cooperates with the convex body 36 to provide further positioning for the sealing ring body 31, reduce the deviation and sliding of the sealing ring body 31, and provide a good seal for the valve core.

[0035] The above description is only a preferred example of the present invention and is not intended to limit the present invention.
