Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and in particular to a ball grinding machine. Background Technology

[0002] In industries such as petroleum, chemical, natural gas, and power, ball valves are crucial fluid control devices with extremely high requirements for sealing performance and reliability. To ensure the safe and stable operation of ball valves under harsh conditions such as high pressure, high temperature, and high corrosion, key components such as the ball and seat of the ball valve require high-precision grinding to guarantee the smoothness and roundness of their sealing surfaces, meeting the stringent requirements of industrial production and maintenance.

[0003] Manual grinding is inefficient and produces poor grinding quality. Currently, most ball valve grinding machines are bulky and can only grind half of the ball at a time. Once the upper half of the ball's sealing surface reaches the required roughness, the ball's position must be readjusted before the lower half can be ground. Furthermore, the grinding process cannot ensure consistency in the amount of grinding on both sides and the roughness of the sealing surface.

[0004] Based on the problems existing in the prior art, this application proposes a new ball grinding machine to solve the above problems. Utility Model Content

[0005] This utility model provides a ball grinding machine, which includes an adjustable support frame that can adapt to the grinding needs of balls of different sizes. It can achieve the grinding operation of the entire ball with only one installation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A ball grinding machine includes a ball, a ball valve bottom ring slidably connected above the ball, a bottom ring clamp above the ball valve bottom ring, and a universal joint above the bottom ring clamp; a support device is provided inside the ball, and the support device is connected to a motor via the universal joint.

[0008] Furthermore, the sphere is an open-ended, hollow sphere, and the supporting device passes through the two openings of the sphere.

[0009] Furthermore, the support device includes a central support column, on which two support frames are slidably connected, and one end of the central support column is connected to the output end of the motor via a universal joint.

[0010] Furthermore, the support frame includes two connecting discs, which are slidably connected to the intermediate support column. A plurality of connecting skeletons are connected between the two connecting discs, and the connecting skeletons are foldable along the middle.

[0011] Furthermore, the intermediate support column is a screw structure, and the connecting disc is threadedly connected to the screw structure; the connecting frame is bolted to the connecting disc.

[0012] Furthermore, the bottom ring clamp includes two vertically connected clamps, and the two ends of the clamps are fixed to the bottom ring of the ball valve by clamping devices.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention achieves cost reduction and efficiency improvement, demonstrating high working efficiency in ball valve grinding equipment. Compared to traditional manual grinding methods, this equipment can complete the grinding of ball valves in a shorter time, making it particularly suitable for grinding batches or large ball valves. This advantage significantly reduces time and labor costs during maintenance.

[0015] Using this invention, omnidirectional spherical grinding can achieve all-round fine grinding without mid-process adjustment; at the same time, the size of the grinding ball can also be adjusted by adjusting the support frame. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] This utility model provides a technical solution: a ball grinding machine, such as... Figure 1 As shown, the device includes a sphere 1, which is a sphere with open ends and a hollow interior. A ball valve bottom ring 2 is slidably connected above the sphere 1. A bottom ring clamp 3 is provided above the ball valve bottom ring 2, and a universal joint 4 is provided above the bottom ring clamp 3. A support device 5 is provided inside the sphere 1, and the support device 5 passes through the two openings of the sphere 1. The support device 5 is connected to the motor 6 through the universal joint 4.

[0024] The support device 5 includes a central support column 51, on which two support frames are slidably connected. One end of the central support column 51 is connected to the output end of the motor 6 via a universal joint 4. A set of universal joints 4 connects the motor 6 to the support device, enabling 360-degree rotation of the sphere 1. The grinding ring of the sphere utilizes the characteristics of the universal joints to automatically adapt to various angles of the sphere. Due to the uniformity and regularity of the rotation, the grinding quality is significantly improved.

[0025] The support frame includes two connecting plates 52, which are slidably connected to the middle support column 51. Several connecting skeletons 53 are connected between the two connecting plates 52, and the connecting skeletons 53 are foldable along the middle.

[0026] The intermediate support column 51 is a screw structure, and the connecting plate 52 is threadedly connected to the screw structure; the connecting frame 53 is bolted to the connecting plate 52.

[0027] The bottom ring clamp 3 includes two vertically connected clamps, and the bottom ring clamp 3 is fixed to the ball valve bottom ring 2 by clamping devices at both ends.

[0028] When grinding the ball valve seat ring, the ball valve seat ring 2 must first be precisely clamped and fixed using the seat ring clamp 3 to ensure that the ball valve seat ring remains stable during the subsequent grinding process.

[0029] Using a support device to support the inside of the ball can further ensure the stability of the ball during the grinding process;

[0030] After applying an appropriate amount of abrasive evenly to the surface of ball 1, start the ball valve grinding equipment to perform all-round grinding on the ball surface (no adjustment of the ball's orientation is required during the grinding process).

[0031] In addition, the bottom of the equipment is designed with a collection tray to recover excess abrasive generated during the grinding process, thereby effectively preventing the abrasive from causing unnecessary pollution to the equipment itself and the surrounding working environment, ensuring a clean and safe work site.

[0032] Thanks to the implementation of automation, work efficiency has been significantly improved. This improvement is not only reflected in faster maintenance speed, but also in a reduction in human error rate and an enhanced ability to handle high-intensity, long-duration tasks.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
