Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring equipment, in particular to a metal sealing ring. Background Art

[0002] Metal sealing rings play a crucial role in turbochargers. They are precisely engineered to withstand high temperatures, high pressures, and rapidly changing operating conditions. These sealing rings typically have a notch design that allows them to deform and contract during installation to fit the sealing grooves of the turbocharger.

[0003] During installation, the metal sealing ring deforms and is placed in the sealing groove of the turbocharger. At this time, the cut end faces of the sealing ring tightly abut against each other, forming a fine gap.

[0004] However, during the operation of the turbocharger, due to the extreme nature of its working environment, this straight gap can become a potential weakness. Under the combined action of high temperature and high pressure, the turbocharger oil may leak slightly through this straight gap. Long-term accumulation will affect the performance and lifespan of the turbocharger, and may even lead to more serious failures. For this reason, we propose a metal sealing ring.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0024] Referring to the attached Figure 1-5, A metal sealing ring, comprising a solid circular metal body 1, and a cut is provided on the body 1. The body 1 itself has elasticity. During installation, the body 1 is squeezed so that the cut abuts, and it can be installed on the sealing pipe wall of the supercharger. The cut is divided into a first connection end and a second connection end. The first connection end is provided with a first step portion 2, and the second connection end is provided with a second step portion 21. The first step portion 2 and the second step portion 21 extend relatively. When the body 1 is squeezed, the first step portion 2 and the second step portion 21 can be detachably and staggeredly engaged, belonging to the way of heaven and earth offset; with this staggered arrangement, the first step portion 2 and the second step portion 21 form multiple contact surfaces, changing a straight gap path formed when the cut abuts into multiple tortuous folded surface paths. Under the combined action of high temperature and high pressure, when the oil fluid passes through the gap, it will be blocked multiple times by the multiple folded surfaces, which can form multi-stage leakage prevention, improve the sealing performance of the metal sealing ring, and also enhance the stability of the overall structure and the anti-deformation ability, so as to achieve the tight fit of the first connection end relative to the second connection end and ensure the tight fit between the connection ends.

[0025] In this embodiment, chamfers 3 are axially provided on both sides of the cut on the body 1. The chamfers 3 are staggeredly arranged and correspond to the first step portion 2 and the second step portion 21. The bottoms of the first step portion 2 and the second step portion 21 are provided with inclined surfaces, corresponding to the inclined end faces of the chamfers 3. After extrusion, abutment is formed, which can enhance the stability of the overall structure and make it more adaptable to the working environment of high temperature and high pressure. Moreover, the chamfers 3 are provided on the side walls of the first step portion 2 and the second step portion 21. When the first step portion 2 and the second step portion 21 abut against the chamfers 3, there will be a tiny gap between them, and the first step portion 2 and the second step portion 21 will block the tiny gap, which can further improve the sealing performance.

[0026] In this embodiment, when the first step portion 2 and the second step portion 21 are engaged with the chamfers 3, a complete circle is formed, which is convenient for installing the sealing ring.

[0027] Furthermore, concave surfaces 4 are staggeredly arranged on the first connection end and the second connection end, and the concave surfaces 4 correspond to the vertical end faces of the chamfers 3.
