Description

Technical Field

[0001] The utility model particularly relates to a high-performance elastic metal valve seat of a G-type butterfly valve. Background Art

[0002] Pipelines are crucial for conveying fluids and controlling hydraulic and pneumatic pressures. Valves are commonly used in various pipelines to connect, close, and regulate flow and pressure to meet production needs. Butterfly valves are widely used due to their simple structure, low cost, and fast opening and closing times. However, due to various operating conditions, some fluid may leak through gaps in the valve body during use. Therefore, a sealing seat is generally required within the valve body. The sealing performance of the seat can affect the life of the valve and hinder the proper operation of the pipeline. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a high-performance elastic metal valve seat for a G-type butterfly valve.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-performance G-type butterfly valve elastic metal valve seat, including a valve seat body, a supporting edge is provided at the outer edge end of the valve seat body, the supporting edge is annularly arranged, a retaining edge is provided on the inner side of the supporting edge, a downwardly recessed buffer groove is formed between the retaining edge and the supporting edge, and an annular convex portion is formed on the inner side of the retaining edge.

[0005] Preferably, an elastic ring with an opening is formed on the annular protrusion.

[0006] Preferably, the opening of the elastic ring is arranged downward.

[0007] Preferably, the cross section of the elastic ring is semicircular.

[0008] Preferably, the buffer tank body is formed with a plurality of corrugated grooves.

[0009] Compared with the prior art, the present invention has the following beneficial effects: the high-performance G-type butterfly valve elastic metal valve seat improves the sealing performance of the butterfly valve during use and effectively extends its service life by setting a buffer groove between the supporting edge and the retaining edge and setting an annular convex portion on the inner side of the retaining edge. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Markings in the figure: 1. Valve seat body; 2. Support edge; 3. Retaining edge; 4. Buffer groove; 5. Ring convex part; 6. Elastic ring; 7. Corrugated groove. DETAILED DESCRIPTION

[0012] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0013] like Figure 1 As shown, a high-performance G-type butterfly valve elastic metal valve seat includes a valve seat body 1, and a supporting edge 2 is provided at the outer edge end of the valve seat body 1. The supporting edge 2 is annularly arranged, and a retaining edge 3 is provided on the inner side of the supporting edge 2. A downwardly recessed buffer groove 4 is formed between the retaining edge 3 and the supporting edge 2, and an annular convex portion 5 is formed on the inner side of the retaining edge 3.

[0014] In this embodiment, an elastic ring 6 with an opening is formed on the annular protrusion 5, which effectively improves the elasticity of the valve seat body 1 and improves the sealing performance during installation.

[0015] In this embodiment, the opening of the elastic ring 6 is arranged downward.

[0016] In this embodiment, the cross section of the elastic ring 6 is semicircular.

[0017] In this embodiment, the buffer groove 4 is formed with a plurality of corrugated grooves 7 to improve the structural strength of the valve seat body 1 .

[0018] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field without departing from the content of the technical solution of the present invention based on the technical essence of the present invention shall fall within the scope of the present invention.
