Description

Technical Field

[0001] The utility model relates to the technical field of sealing gaskets, in particular to an assembled toothed sealing gasket. Background Art

[0002] Toothed gaskets are usually composed of a metal core (such as stainless steel) covered with high-temperature and corrosion-resistant materials such as flexible graphite and polytetrafluoroethylene. Their unique tooth-shaped structure allows the bolt load to be concentrated on a smaller sealing surface to achieve a tight seal. Toothed gaskets are widely used in high-temperature, high-pressure, and steam pipelines in oil refining, chemical, petrochemical plants, as well as power generation and nuclear power plants. They are ideal sealing materials for flange connections and valve cover connections.

[0003] A search revealed a Chinese patent with the patent publication number CN205207667U, which discloses a metal toothed gasket comprising an annular metal gasket body, wherein the upper and lower sealing surfaces of the metal gasket body are each provided with concentric toothed rings. The invention is characterized in that the upper and lower sealing surfaces of the metal gasket body are each configured to bulge outward in the middle and then gradually recede inward on both sides, thereby making the metal gasket body have a radial cross-section that is thick in the middle and gradually thinner on both sides. Compared with the prior art, the invention has the advantages of: by processing the upper and lower sealing surfaces of the metal gasket body into bulging outward in the middle and then gradually receding inward on both sides, when the metal toothed gasket is used, the concentric teeth located in the middle portion of the sealing surface can first perform a sealing function, and only a low preload pressure is required, which can effectively reduce the workload during gasket installation; in addition, when the medium erodes the gasket and leaks, the gasket can be re-pressed, allowing the concentric teeth that were originally unstressed (or less stressed) to also perform a sealing function.

[0004] However, the above design still has some shortcomings. The sealing gasket in the above design is not easy to assemble and is not convenient for users to use during installation, and it is difficult to meet the user's needs. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled toothed sealing gasket, which solves the problem that the through sealing gasket in the background art is inconvenient to assemble and use during installation, and is difficult to meet the needs of users.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A assembled toothed sealing gasket comprises a gasket body, a surface of which is provided with a plurality of mounting holes, an outer wall of which is fixedly connected with a plurality of connecting plates, both ends of which are fixedly connected with an L-shaped plate, a surface of which is provided with a screw hole, an inner wall of which is threadedly connected with a screw rod, and the screw rod is installed in one of the mounting holes, and a nut is threadedly provided on the outer wall of the screw rod.

[0008] Preferably, the front end surface of the gasket body is provided with a first toothed ring, and the rear end surface of the gasket body is provided with a second toothed ring.

[0009] Preferably, the first toothed ring and the second toothed ring are identical in size and shape.

[0010] Preferably, the number of the mounting holes is eight, and the inner walls of the mounting holes and the screw holes are both provided with internal threads that are compatible with the screw rods.

[0011] Preferably, the number of the screws is four, and the number of the L-shaped plates is eight.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. Through the structural design of the gasket body, L-shaped plate, mounting hole, screw, nut and screw hole, the sealing gasket and the flange can be easily installed through the mutual cooperation of multiple L-shaped plates. At the same time, after the gasket and the flange are connected, the screw is aligned with the screw hole and the mounting hole, and then the screw is screwed into the mounting hole and the screw hole respectively, and then the nut is screwed into the screw for reinforcement, thereby facilitating assembly and further facilitating use by users.

[0014] 2. Through the cooperation between the first toothed ring and the second toothed ring, it is convenient to seal the two flanges at the same time, avoiding the need for two sealing gaskets, thereby reducing losses and better meeting the use requirements of different scenarios.
