Embodiment Construction

[0017] The ball valve of the present invention will be further described below with reference to the accompanying drawings.

[0018] Such as figure 1 The ball valve shown is a ball valve with a spiral noise reduction function, which is used in the field of water supply and drainage in buildings. Fixed, a ball valve 3 is fixed between the ball valve body 1 and the ball valve cap 2, clamped by the sealing ring 4 on both sides, and three spiral guide ribs 30 are formed on the inner wall of the valve ball 3, and the cross section of the guide rib 30 It is a triangular protrusion, and the top of the triangular protrusion is arc-shaped. The diversion rib 30 is used to divert the flow of water in the pipeline, reduce the impact of the water flow, and reduce the noise. The angle between the diversion rib 30 and the center line of the valve ball is 8°; The included angle between the center line of the valve ball is 3° to 50°, and the number of diversion ribs 30 can be two, three, or ...

Abstract

The invention relates to a ball valve in the building water supply and drainage pipeline field. The ball valve comprises a ball valve body, a ball valve cap matched with the ball valve body and a valve ball arranged between the ball valve body and the ball valve cap, wherein the valve ball is clamped by sealing rings 4 at the two sides, more than one diversion rib is arranged on the inner wall of the valve ball, and an included angle between the diversion rib and the center line of the valve ball is in the range of 3-50 degrees. In the ball valve with the valve ball having a spiral silencing function, a fluid medium is guided via the spiral diversion rib on the valve ball, fluid impact is reduced, so that noise is reduced; and compared with the prior art, the ball valve has the advantages of simple structure, low processing difficulty and high practicability, can be applicable to normal and required building occasions, and has high product additional value and good market demand.

Description

technical field [0001] The invention relates to a ball valve in the field of building water supply and drainage pipelines. Background technique [0002] Valves, especially ball valves, are commonly used hardware for building water supply and drainage pipes. During the operation of the pipeline, due to changes in water pressure and velocity, it is easy to generate continuous noise when it hits the pipeline wall and valves, especially when there is air in the shaft or pipeline, the noise is more obvious. In some occasions with special noise control, such as laboratories, high-end buildings, libraries, etc., ordinary ball valves cannot achieve the function of noise reduction. [0003] The existing technology with similar functions is described in the patent "Low Noise Ball Valve" with the notification number CN202545873U. There are several labyrinth small holes on the side wall of the valve ball part of the ball valve, and another enough groove is opened that is the same as th...
