Technical Field
[0001] This application relates to the field of valve body sealing ring processing technology, and in particular to valve body sealing ring processing apparatus. Background Technology
[0002] A valve is defined as a device in a fluid system used to control the direction, pressure, and flow rate of a fluid. Valves are devices that allow the flow or stop of media (liquids, gases, powders) within piping and equipment, and can control their flow rate.
[0003] In the production process of valve body, in order to ensure better sealing inside the valve body in the closed state, sealing rings are required. In the processing of valve body sealing rings, the sealing rings need to be ground to obtain a smoother surface or to be ground into a shape with corresponding angles. However, due to the lightweight nature of rubber sealing ring materials, they are not easy to fix during grinding, and are prone to shaking, which can lead to grinding damage. Utility Model Content
[0004] To address the problem that existing valve body seals are difficult to fix during grinding, and are prone to shaking and damage during grinding, this application provides a valve body seal processing device.
[0005] The valve body sealing ring processing device provided in this application adopts the following technical solution:
[0006] A valve body sealing ring processing device includes a base and a support frame fixedly mounted on the base. A U-shaped box integrally formed with the support frame is provided on one side. A limiting cylinder for fixing the sealing ring is installed inside the U-shaped box, and an opening for placing the sealing ring is opened on the side away from the support frame. A turntable is installed outside the support frame through one end of the limiting cylinder. A housing is installed on the outside of the turntable, and an air pump is installed inside the housing. Multiple through holes are equally spaced on the outer circumference of the limiting cylinder. Positioning plates are slidably installed in the through holes. An extrusion mechanism for driving the multiple positioning plates to move synchronously is installed inside the limiting cylinder.
[0007] Preferably, a mounting groove is provided on the upper end of one side of the support frame, a motor is installed in the mounting groove, the output shaft end of the motor extends to the outside of the support frame and a sealing ring is fixed thereon, and a gear ring that meshes with the sealing ring is fixed on the outer side of the turntable.
[0008] Preferably, the extrusion mechanism includes a support shaft installed inside the limiting cylinder. Both ends of the support shaft are fixed to the inner wall of the limiting cylinder via connecting rods, and an annular airbag is sleeved on the outer side. The input end of the annular airbag is connected to the output end of the air pump via an air inlet pipe, and the output end of the annular airbag is connected to an exhaust pipe. A check valve is installed inside the air inlet pipe, and a solenoid valve is installed inside the exhaust pipe.
[0009] Preferably, a spring is connected between the lower end of the positioning plate and the inner wall of the limiting cylinder, and anti-slip protrusions are provided at equal intervals on the outer surface.
[0010] Preferably, a chip discharge port is provided at the bottommost end of the U-shaped box, and a matching stop can be detachably installed at the chip discharge port.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This valve body sealing ring processing device, during fixing, involves placing the sealing ring outside the limiting cylinder, starting the air pump to inject gas into the annular air bladder, causing it to push the positioning plate outward to support the sealing ring, thus fixing the sealing ring. After processing, when it is necessary to remove the sealing ring, the solenoid valve is opened to release the gas from the annular air bladder, ceasing the compression of the positioning plate. At this time, the spring returns to its elasticity, driving the positioning plate to reset and compressing the annular air bladder to expel the internal gas, thereby releasing the sealing ring from its fixation. This device achieves the effect of fixing sealing rings of different sizes during processing. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1 to 3 This utility model provides a technical solution:
[0019] A valve body sealing ring processing device includes a base 1 and a support frame 2 fixedly mounted on the base 1. A U-shaped box 3 integrally formed therewith is provided on one side of the support frame 2. A limiting cylinder 4 for fixing the sealing ring is installed inside the U-shaped box 3, and an opening for placing the sealing ring is opened on the side away from the support frame 2. One end of the limiting cylinder 4 extends through to the outside of the support frame 2 and a turntable 5 is installed. A housing 6 is installed on the outside of the turntable 5. An air pump is installed inside the housing 6. Multiple through holes are equally spaced on the outer circumference of the limiting cylinder 4. Positioning plates 7 are slidably installed in the through holes. An extrusion mechanism for driving the multiple positioning plates 7 to move synchronously is installed inside the limiting cylinder 4.
[0020] The extrusion mechanism includes a support shaft 11 installed inside the limiting cylinder 4. Both ends of the support shaft 11 are fixed to the inner wall of the limiting cylinder 4 via connecting rods 12. An annular airbag 13 is sleeved on the outside. The input end of the annular airbag 13 is connected to the output end of the air pump via an air inlet pipe 15. The output end of the annular airbag 13 is connected to an exhaust pipe 14. A check valve is installed inside the air inlet pipe 15, and a solenoid valve is installed inside the exhaust pipe 14.
[0021] During fixing, the sealing ring is placed on the outside of the limiting cylinder 4, the air pump is started, and gas is injected into the annular airbag 13, causing the annular airbag 13 to expand and push the positioning plate 7 outward, so that the positioning plate 7 extends outward from the limiting cylinder 4 and compresses the spring 16. The positioning plate 7 supports the sealing ring, thereby fixing the sealing ring. When the sealing ring needs to be removed after processing, the solenoid valve is opened to release the air from the annular airbag 13, and the positioning plate 7 is no longer compressed. At this time, the spring 14 returns to its elasticity, driving the positioning plate 7 to reset. At the same time, the annular airbag 13 is compressed to release the internal gas, thereby releasing the fixing of the sealing ring. This achieves the effect of fixing sealing rings of different sizes during processing.
[0022] A spring 16 is connected between the lower end of the positioning plate 7 and the inner wall of the limiting cylinder 4, and multiple anti-slip protrusions 17 are evenly spaced on the outer surface, thereby improving the anti-slip performance of the positioning plate 7.
[0023] At the bottom of the U-shaped box 3, there is a chip discharge port 18. A matching stop can be detached and installed at the chip discharge port 18. After processing, the stop can be removed, and the waste generated during the process can be discharged from the chip discharge port 18.
[0024] A mounting groove is provided on the upper end of one side of the support frame 2. A motor 8 is installed in the mounting groove. The output shaft of the motor 8 extends to the outside of the support frame 2 and a gear 9 is fixed thereon. A gear ring 10 that meshes with the gear 9 is fixed on the outside of the turntable 5. When it is necessary to change the processing position of the sealing ring, the motor 8 is started to drive the gear 9 to rotate. Through the meshing action of the gear ring 10 and the gear 9, the turntable 5 and the limiting cylinder 4 are driven to rotate, so that the sealing ring can be rotated and adjusted as needed during processing.
