Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, specifically to a valve grinding device for valve manufacturing. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. During valve manufacturing, a grinding device is used to grind the valve body surface. For example, patent application number 202121790803.3, entitled "A Valve Grinding Device for Valve Manufacturing," includes a mounting plate. A support plate is fixedly connected to the upper surface of the mounting plate. A rotating rod is rotatably connected to the upper end of the mounting plate via a bearing. The rotating rod is slidably connected to a first sliding groove via a first sliding... The first sliding rod is engaged with the valve body via a limiting block. The mounting plate is equipped with a grinding head via a connecting rod. This valve grinding device is used for valve production. The limiting block, supported by a first spring, can engage valve bodies of different models. The rubber layer prevents the valve body from slipping and protects it. By engaging with the locking post and different locking slots, the position of the sliding plate is adjusted so that the grinding brush is aligned with the two side tubes of the valve body, allowing for the grinding of different models of valve bodies. Simultaneously, supported by a second spring, the grinding brush is kept in close contact with the two side tubes of the valve body. The V-shaped trajectory of the grinding brush at the right end increases the contact area with the two side tubes of the valve body, thus improving the grinding quality.

The drawer 13 is aligned with the discharge mesh plate 12. The front of the drawer 13 extends into the exterior of the outer casing 1. An auxiliary mechanism is provided on the back of the drawer 13.

[0030] As a technical optimization of this utility model, by setting up a discharge mesh plate 12, the waste chips enter the interior of the outer shell 1, and the drawer 13 is used to collect the chips together, making it convenient for workers to process the chips.

[0039] The working principle and usage process of this utility model are as follows: When in use, first put the valve body on the limiting block 8, then start the motor 4. The motor 4 drives the grinding wheel 5 to rotate through the output end. The grinding wheel 5 drives the auxiliary plate 7 and the limiting block 8 to rotate in the opposite direction through the transmission device 6. The limiting block 8 will drive the valve body to rotate in the opposite direction. The grinding wheel 5 grinds the valve body by rotating, which will generate a large amount of debris. At this time, start the air pump 11. The air pump 11 will deliver air into the annular air knife 10. The annular air knife 10 will spray out the air to form an air wall. The air wall is used to block the debris and prevent the debris from flying everywhere.

[0040] In summary, this valve grinding device for valve production, by setting up an air pump 11 and an annular air knife 10, blows out a high-speed airflow, thereby forming an air wall. The air wall is used to block the flying debris, preventing the debris from flying everywhere and causing injury to workers, thus improving the safety of the grinding device.
