Description

Technical Field

[0001] The utility model relates to the technical field of balls of ball valves, in particular to a Y-shaped ball used on a valve. Background Art

[0002] The V-type ball valve ball is a specially designed ball valve structure. The shape of its ball presents an outline similar to the letter "V". Unlike traditional ball valves, in the open state, the V-shaped hole of the V-type ball valve ball will match the fluid channel of the pipeline, allowing the fluid to pass smoothly. In the closed state, the ball will rotate so that the V-shaped hole does not match the fluid channel of the pipeline, thereby achieving fluid cutoff. When the V-type ball valve ball is in the channel of the closed valve body, it can cut off some crystalline particles through the V-shaped incision on one side to avoid channel blockage and wear of the sealing surface by approaching particles. As a result, the V-shaped cross-section of the V-type ball is greatly worn after long-term use, and the entire ball needs to be disassembled and replaced when replaced, resulting in high maintenance costs.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example: As attached Figure 1 ~Attached Figure 4The Y-shaped ball used in the valve shown in the figure comprises a ball 1, a V-shaped section 2 is provided on one side of the ball 1, a V-shaped cutter 3 is installed on the V-shaped section 2, both ends of the V-shaped cutter 3 are clamped and arranged on the V-shaped section 2, a plurality of mounting seats 4 are arranged on the inner circumference of the ball 1 and on one side close to the V-shaped cutter 3 (one to three can be installed according to the size of the ball valve), a clamping protrusion 5 (specifically an integrated structure) adapted to the mounting seat 4 is arranged on the V-shaped cutter 3, and a fastener 8 (specifically a bolt) for locking the clamping protrusion 5 is arranged on the mounting seat 4. The traditional one-piece V-shaped sphere 1 is divided into two parts, the sphere 1 and the V-shaped opening. During installation, the snap-fit ​​protrusion 5 is connected to the mounting seat 4, and a tight connection with the sphere 1 is achieved through a number of conical protrusions 12. When the fastener 8 tightens the sphere 1 and the V-shaped opening, the eccentric screw hole between the two components is used to clamp the sphere 1 and reduce the connection gap between the sphere 1 and the V-shaped opening. A number of reinforcing ribs 15 are arranged in an array on the scraping bevel 14, the purpose of which is to enhance the structural strength of the scraping bevel 14 and effectively reduce the problem of cracks on the scraping bevel 14 during the scraping operation.

[0017] As attached Figure 2 and attached Figure 3 As shown, the mounting seat 4 is provided with a mounting groove 9 which is compatible with the snap-on protrusion 5, the snap-on protrusion 5 is provided with a first screw hole 10, and the mounting groove 9 is provided with a second screw hole 11 which is eccentrically arranged with respect to the first screw hole 10. The fastener 8 passes through the first screw hole 10 in sequence and is tightened in the second screw hole 11. The eccentric tightening installation method can eliminate the gaps and errors generated during the processing, and can further improve the connection tightness between the two components.

[0018] As attached Figure 2 ~Attached Figure 4 As shown, the V-shaped cutter 3 is provided with a plurality of conical protrusions 12 (specifically an integrated structure, and two are provided) on the side facing the V-shaped section 2, and the conical protrusions 12 are provided in a gradually shrinking state toward the side of the V-shaped section 2, and a conical opening 13 adapted to the conical protrusions 12 is provided on one side of the V-shaped section 2. When the sphere 1 is in a rotating operation, the connection between the V-shaped cutter 3 and the V-shaped section 2 will be collided and squeezed by the pipeline, valve seat or seal, resulting in a gap between the V-shaped cutter 3 and the V-shaped section 2. However, after the conical protrusions 12 are provided, corresponding pulling force and resistance will be generated when collision and squeezing occur, thereby preventing the V-shaped cutter 3 from tilting to one side, thereby avoiding the generation of gaps and the penetration of crystal particles.

[0019] As attached Figure 1 ~Attached Figure 3As shown, the V-shaped cutter 3 is provided with a scraping bevel 14 on the side away from the V-shaped cut surface 2. The scraping bevel 14 is arranged at an angle with the V-shaped cut surface 2, which can improve the smoothness of the scraping operation and improve the scraping efficiency.

[0020] As attached Figure 4 As shown, a plurality of reinforcing ribs 15 (specifically an integrated structure) are arranged in an array on the scraping bevel 14. The reinforcing ribs 15 are arranged in an arc-shaped convex state, which can enhance the structural strength of the scraping bevel 14, greatly reduce the problem of cracks on the scraping bevel 14, and improve the service life of the V-shaped cutter 3.
