[0024] Embodiment

[0025] Please refer to Figures 1 - 3 , which shows the structural schematic diagram of the erosion - proof ball basket for repeatedly switching a bypass valve in the embodiment of the present utility model;

[0026] This embodiment provides an erosion - proof ball basket for repeatedly switching a bypass valve, including a sphere carrier tube 1, a goal end 2 and a fixed end 3 connected to both ends of the sphere carrier tube 1. The sphere carrier tube 1 is detachably connected to the goal end 2 and the fixed end 3 respectively;

[0027] Inside one end of the sphere carrier tube 1 close to the fixed end 3, there is a ball blocking ring 11. The center of the ball blocking ring 11 has a liquid channel 111. The ball blocking ring 11 is provided with an arc - shaped diversion hole 112 on the outside of the liquid channel 111. One side edge of the ball blocking ring 11 facing the goal end 2 is provided with an annular diversion plate 12; one end of the diversion plate 12 is attached to the inner wall of the sphere carrier tube 1, and the other end of the diversion plate 12 is attached to the ball blocking ring 11 and is connected to one end of the diversion hole 112.

[0028] Next, the erosion - proof ball basket for repeatedly switching a bypass valve in this exemplary embodiment will be further described.

[0029] In some embodiments of the present application, the above-mentioned ball basket is composed of three parts, namely a sphere carrier cylinder 1, a goal end 2, and a fixed end 3. The sphere carrier cylinder 1 is detachably connected to the goal end 2 and the fixed end 3 respectively, so that the three parts can be produced separately, produced independently in batches, improving production efficiency and reducing production costs. At the same time, it is divided into a three-section structure, and different materials can be used for production according to the different impact forces of the liquid on different parts of the ball basket, thereby improving the overall wear and erosion resistance of the ball basket.

[0030] As a preferred implementation manner, external threads 13 are respectively provided at both ends of the above-mentioned sphere carrier cylinder 1, and internal threads 21 adapted to the external threads 13 are respectively provided on the inner walls of the goal end 2 and the fixed end 3. That is, the sphere carrier cylinder 1 is threadedly connected to the goal end 2 and the fixed end 3, which is convenient for connection and disassembly.

[0031] In some embodiments of the present application, a ball blocking ring 11 is provided inside one end of the above-mentioned sphere carrier cylinder 1 close to the fixed end 3. A liquid passage 111 is provided at the center of the ball blocking ring 11 for the liquid to flow through. An arc-shaped diversion hole 112 is provided on the ball blocking ring 11 outside the liquid passage 111, and an annular diversion plate 12 is provided on the edge of the ball blocking ring 11 facing the goal end 2. One end of the diversion plate 12 is attached to the inner wall of the sphere carrier cylinder 1, and the other end of the diversion plate 12 is attached to the ball blocking ring 11 and connected to one end of the diversion hole 112. The above-mentioned ball blocking ring 11 is used to block the switch valve sphere and allow the liquid to pass through. By providing an annular diversion plate 12 on the side of the ball blocking ring 11 close to the switch valve sphere, on the one hand, the diversion plate 12 absorbs the fluid impact energy, and on the other hand, it disperses the fluid kinetic energy, thereby reducing the direct impact of the liquid on the ball blocking ring 11. By providing a diversion hole 112 on the ball blocking ring 11 and connecting it to the diversion plate 12, when the switch valve sphere comes to block the liquid passage 111, the liquid can still flow through the diversion hole 112. Through the mutual cooperation of the diversion plate 12 and the diversion hole 112, the fluid kinetic energy is further dispersed, and the erosion resistance is further improved.

[0032] As a preferred implementation manner, the outer wall of the above-mentioned diversion plate 12 is attached to the ball blocking ring 11 and the sphere carrier cylinder 1, and the inner wall of the diversion plate 12 is an arc-shaped concave towards the inner wall of the sphere carrier cylinder 1. The diversion plate 12 is designed as an inner concave arc. When the fluid impacts the diversion plate 12 along the curve, part of the impact energy is absorbed by the diversion plate 12, and then flows along the curve, reducing the fluid resistance and guiding the fluid to be evenly distributed to avoid local high-speed erosion.

[0033] As a preferred implementation manner, the above-mentioned diversion plate 12 is detachably connected to the sphere carrier cylinder 1 through a connector 14, and the connector 14 passes through the outer wall of the sphere carrier cylinder 1 and is connected to the outer wall of the diversion plate 12. The diversion plate 12 is set as a detachable connection structure, so that the diversion plate 12 can be replaced, improving the overall life of the ball basket.

[0034] Specifically, the connecting member 14 can be a connecting screw. Two connecting members 14 with different lengths are arranged along the length direction of the ball basket. In this way, the connection stability of the deflector 12 can be improved. Moreover, the connecting member 14 penetrates and connects from the outside of the ball basket and is inserted into the solid part of the deflector 12, making the connection firm and the disassembly convenient.

[0035] As a preferred implementation manner, a steel ring 15 is elastically connected to the inner wall of the above-mentioned spherical carrier cylinder 1. The steel ring 15 protrudes from the inner wall of the spherical carrier cylinder 1. The steel ring 15 is located in front of one end of the deflector 12 away from the ball blocking ring 11 and has a buffer gap with the deflector 12.

[0036] By arranging the elastically connected steel ring 15 at the front end of the deflector 12, on the one hand, since the deflector 12 is detachably connected, the protruding part of the steel ring 15 can effectively prevent the fluid medium from continuously impacting the deflector 12 and washing away the deflector 12. On the other hand, the elastically connected steel ring 15 can play a buffering role for the fluid. The steel ring 15 is made of a material with high wear resistance and erosion resistance. Through the buffer gap between the steel ring 15 and the deflector 12, the fluid is not easy to impact the deflector 12 and the ball blocking ring 11 at the rear end.

[0037] Furthermore, an annular groove 16 is formed in the inner wall of the above-mentioned spherical carrier cylinder 1. A part of the steel ring 15 is embedded in the annular groove 16 and is connected to the annular groove 16 through a spring 17.

[0038] As a preferred implementation manner, both ends of the above-mentioned diversion hole 112 are arc-shaped openings, and the inner wall of the diversion hole 112 is a bent arc. When the fluid flows through the diversion hole 112, the bent arc absorbs the kinetic energy of the fluid, playing a buffering role and avoiding large erosion of the fixed end 3 by the fluid.

[0039] As a preferred implementation manner, the connection between the above-mentioned diversion hole 112 and the deflector 12 is in arc transition, that is, it is designed to be streamlined to reduce fluid resistance.

[0040] As a preferred implementation manner, at least two of the above-mentioned diversion holes 112 are provided, and the two diversion holes 112 are opposite and adjacent to each other. The two diversion holes 112 can improve the dispersion effect of the fluid and thus improve the erosion resistance effect.

[0041] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
