Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to a ball valve, in particular to a new type of high-efficiency sealing ball valve. Background Art

[0002] Ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. The end of the ball valve body is usually connected to a pipeline, and then connected to the corresponding water pipe fittings through the pipeline. During the production process, sealing glue is applied between the valve body and the pipeline to improve the sealing performance. However, in actual production, it is found that the glue application will produce uneven glue application, resulting in poor sealing effect of the ball valve in later use and water leakage. Summary of the invention

[0003] The utility model aims to solve the above problems existing in the prior art and provides a new ball valve which can improve the sealing performance and prevent water leakage.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A new type of ball valve with high efficiency sealing, including a valve body, the port of the valve body is internally threadedly connected to a pipeline, characterized in that a sealing groove is opened on the pipeline, the end of the valve body extends to have an extended flange that abuts against the pipeline and hides the sealing groove inside, a sealing ring is sealed in the sealing groove, the sealing ring is surrounded by the valve body, the extended flange and the pipeline, and a sealing device is also installed at the outer end of the pipeline;

[0005] The sealing device comprises a sealing body, a sealing outer lip extending outward from the outer ring of the sealing body, and a sealing inner lip extending outward from the inner ring of the sealing body. The outer end of the sealing body is integrally formed with a plurality of sealing protrusions protruding outward and spaced apart inside and outside.

[0006] In the above-mentioned novel ball valve with high efficiency sealing, a locking nut is connected to the external thread on the pipeline.

[0007] In the above-mentioned novel ball valve with high efficiency sealing, a ball is arranged in the valve body.

[0008] Compared with the prior art, the new ball valve with high efficiency sealing has the advantages of improving sealing performance, reducing the complicated process of gluing and sealing, and preventing water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In the figure, 1. valve body; 2. pipe; 3. extension flange; 4. sealing ring; 5. sealing body; 6. sealing outer lip; 7. sealing inner lip; 8. sealing protrusion; 9. locking nut; 10. ball; 11. pipe fitting. DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the new type of high-efficiency sealed ball valve comprises a valve body 1, a pipe 2 is connected to the internal thread of the port of the valve body 1, a sealing groove is opened on the pipe 2, an extended flange 3 is extended from the end of the valve body 1 to abut against the pipe 2 and hide the sealing groove inside, a sealing ring 4 is sealed and installed in the sealing groove, and the sealing ring 4 is surrounded by the valve body 1, the extended flange 3 and the pipe 2, and a sealing device is also installed at the outer end of the pipe 2.

[0014] Preferably, the sealing device includes a sealing body 5, a sealing outer lip 6 extending outward from the outer circle of the sealing body 5, and a sealing inner lip 7 extending outward from the inner circle of the sealing body 5. The outer end of the sealing body 5 is integrally formed with a plurality of sealing protrusions 8 that protrude outward and are spaced apart inside and outside.

[0015] To elaborate further, a locking nut 9 is connected to the external thread of the pipe 2, and a corresponding water pipe fitting 11 can be installed at the outer end of the pipe 2 and locked with the locking nut 9. Therefore, the sealing device formed between the pipe fitting 11 and the pipe 2 can effectively seal, wherein the sealing outer ring and the sealing inner ring have an extended sealing surface to achieve a long-term sealing effect, and the sealing protrusion 8 increases the contact pressure between the pipe fitting 11 as the locking nut 9 is locked, thereby achieving an efficient sealing effect.

[0016] Preferably, a ball 10 is disposed in the valve body 1 .

[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0018] Although the terms valve body 1, pipe 2, extended flange 3, sealing ring 4, sealing body 5, sealing outer lip 6, sealing inner lip 7, sealing protrusion 8, locking nut 9, ball 10, pipe fitting 11 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
