Description

Technical Field

[0001] This utility model relates to the field of ball valve core maintenance tooling technology, and in particular to a ball valve core grinding device. Background Technology

[0002] In chemical industrial production, ball valves are important components installed on pipelines to control the flow of chemical media. After long-term use, material media, especially viscous materials that are easy to settle, will adhere to the valve core. If used intermittently for a long time, rust will occur. The adhered material or rust will cause the valve core to not open or close properly, affecting normal production.

[0003] The current method involves disassembling the ball valve from the pipeline and removing the valve core from the ball valve. The valve core is then placed on a platform and manually rotated while being sanded with sandpaper. This process is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a ball valve core grinding device that is beneficial to improving grinding efficiency.

[0005] This utility model is implemented by the following technical solution: a ball valve core grinding device, which includes a motor, a grinding platform, a support leg, a turntable, and a pressure rod; the support leg is fixed to the bottom of the grinding platform, the motor is installed below the grinding platform, the output shaft of the motor passes through the grinding platform upward and is connected to the turntable, and the turntable is set to rotate horizontally; the pressure rod is provided above the turntable, and clamping screws are provided at both ends of the pressure rod, and the ends of the clamping screws are screwed to the turntable.

[0006] Furthermore, it also includes a washer ring fixed to the top surface of the turntable, the inner edge of which is chamfered.

[0007] Furthermore, the washer ring is made of plastic.

[0008] Furthermore, a rubber pad is fixed to the bottom surface of the pressure rod.

[0009] Furthermore, it also includes a grinding bracket, the bottom end of which is fixed to the grinding platform. A grinding connecting plate is connected to the grinding bracket above the turntable via a connecting assembly, and sandpaper is adhered to the bottom surface of the grinding connecting plate.

[0010] Furthermore, the bottom surface of the grinding connecting plate is spherical.

[0011] Furthermore, the connecting assembly includes a screw, a guide rod, a compression spring, and a limiting nut; the bottom end of the screw is fixed to the top surface of the grinding connecting plate, and the top end of the screw passes through the grinding bracket and is screwed with the limiting nut; the guide rods are symmetrically arranged on both sides of the screw, the bottom end of the guide rod is connected to the top surface of the grinding connecting plate, the top end of the guide rod slides through the grinding bracket, and the compression spring is sleeved on the guide rod between the grinding bracket and the grinding connecting plate.

[0012] Furthermore, the grinding support includes a vertical beam, a horizontal beam, and a connecting beam. The bottom end of the vertical beam is fixed to the grinding platform, one end of the horizontal beam is fixed to the vertical beam, and the other end of the horizontal beam is fixed to the connecting beam, which is placed above the pressure rod. The connecting beam is connected to the connecting assembly.

[0013] The advantages of this invention are as follows: When grinding the valve core, the valve core is fitted onto the pressure rod, and the clamping screws at both ends of the pressure rod are tightened onto the turntable. At the same time, the pressure rod presses the valve core firmly onto the turntable. While the motor drives the turntable to rotate, the pressure rod and the valve core rotate synchronously. During this process, sandpaper is used to grind the outer wall of the valve core to remove long-term accumulated materials or rust. This ensures that after the polished valve core is installed in the ball valve, it can continue to be effectively used in production, ensuring that the ball valve is closed properly and preventing leakage.

[0014] After the valve core is pressed onto the turntable by the pressure rod, the sandpaper on the sanding connecting plate contacts the top surface of the valve core under the action of the connecting component. While the motor drives the turntable 4 to rotate, the top of the valve core is sanded by the sandpaper. There is no need for manual holding of the sandpaper to sand it, which reduces labor intensity.

[0021] like Figure 1 and Figure 2 As shown, this embodiment provides a ball valve core grinding device, which includes a motor 3, a grinding platform 1, a support leg 2, a turntable 4 and a pressure rod 5; the support leg 2 is fixed at the bottom of the grinding platform 1, and the motor 3 is installed below the grinding platform 1. The output shaft of the motor 3 passes through the grinding platform 1 and is connected to the turntable 4. The turntable 4 is set to rotate horizontally, and the motor 3 can drive the turntable 4 to rotate.

[0022] A pressure rod 5 is provided above the turntable 4. The two ends of the pressure rod 5 are fitted with clamping screws 6, and the ends of the clamping screws 6 are screwed to the turntable 4. When grinding the valve core 9, the valve core 9 is fitted onto the pressure rod 5 and tightened onto the turntable 4 using the clamping screws 6 at both ends of the pressure rod 5. At the same time, the pressure rod 5 presses the valve core 9 onto the turntable 4. While the motor 3 drives the turntable 4 to rotate, the pressure rod 5 and the valve core 9 rotate synchronously. During this process, sandpaper is used to grind the outer wall of the valve core 9 to remove the long-term accumulated and adhered materials or rust marks, ensuring that the ground valve core 9 can continue to be effectively used in production after being installed in the ball valve, ensuring that the ball valve is closed in place and preventing leakage.

[0023] It also includes a washer 7 fixed at the center of the top surface of the turntable 4. The washer 7 is made of plastic. After the valve core 9 is fitted onto the pressure rod 5, the pressure rod 5 presses the valve core 9 onto the plastic washer 7 instead of pressing it directly onto the iron turntable 4, so as to avoid damage to the valve core 9. A rubber pad 8 is fixed on the bottom surface of the pressure rod 5. The pressure rod 5 contacts the inside of the valve core 9 through the rubber pad 8. The inner edge of the washer 7 is chamfered to avoid damage to the valve core 9.

[0024] It also includes a grinding support 10, which includes a vertical beam 10.1, a horizontal beam 10.2, and a connecting beam 10.3. The bottom end of the vertical beam 10.1 is fixed to the grinding platform 1.

A connecting assembly 11 is connected to the connecting beam 10.3. A grinding connecting plate 12 is connected to the grinding support 10 via the connecting assembly 11. The bottom surface is a concave spherical surface, and sandpaper 13 is adhered to the bottom surface of the grinding connecting plate 12. After the pressure rod 5 presses the valve core 9 onto the turntable 4, the sandpaper 13 on the grinding connecting plate 12 contacts the top surface of the valve core 9. While the motor 3 drives the turntable 4 to rotate, the sandpaper 13 grinds the top of the valve core 9. It does not require manual holding of the sandpaper 13 to grind it, reducing labor intensity. When grinding the bottom of the valve core 9, the clamping screw 6 is loosened and the position of the valve core 9 on the pressure rod 5 is adjusted.

[0025] The connecting assembly 11 includes a screw 11.1, a guide rod 11.2, a compression spring 11.3, and a limiting nut 11.4. The bottom end of the screw 11.1 is fixed to the top surface of the grinding connecting plate 12, and the top end of the screw 11.1 passes through the connecting beam 10.3 of the grinding bracket 10 and is screwed with the limiting nut 11.4. The limiting nut 11.4 abuts against the top surface of the connecting beam 10.3. Guide rods 11.2 are symmetrically arranged on both sides of the screw 11.1. The bottom end of the guide rod 11.2 is connected to the top surface of the grinding connecting plate 12, and the top end of the guide rod 11.2 slides through the connecting beam 10.3. A compression spring 11.3 is sleeved on the guide rod 11.2 between the connecting beam 10.3 and the grinding connecting plate 12. After the valve core 9 is inserted into the pressure rod 5 and placed on the washer 7, the sandpaper 13 on the grinding connecting plate 12 is tightly attached to the valve core 9 under the action of the compression spring 11.3.
