Description

Technical Field

[0001] This utility model relates to the field of valve sealing technology, and in particular to a valve sealing replacement assembly. Background Technology

[0002] Valves are an important component of fluid control systems, used to regulate, control, or shut off fluids in pipelines. Butterfly valves, as common fluid control valves, are widely used in water supply, gas supply, petroleum, chemical and other fields. Butterfly valves have a simple structure, are lightweight, and open and close quickly, making them suitable for controlling a variety of fluids. However, with prolonged use, the internal seals of butterfly valves (sealing rings, gaskets, etc.) are prone to failure due to wear, aging or corrosion, leading to valve leakage and affecting the normal use of the valve and the sealing performance of the fluid system.

[0003] Existing butterfly valves require frequent opening and closing of the valve plate. During this process, the valve plate is in frequent contact with the sealing element, which can easily cause wear on the sealing element, reducing its sealing performance and resulting in poor sealing. The existing patent (publication number: CN211951469U) describes a butterfly valve with good sealing stability. This utility model effectively makes the sealing ring resistant to high and low temperatures, corrosion, and stability through a high-temperature resistant layer, a corrosion-resistant layer, a low-temperature resistant layer, a reinforcing layer, and an aging-resistant layer. It increases the adhesion between the elastic ring and the sealing ring, thereby improving the sealing performance. The use of two valve plates further improves the sealing performance of the butterfly valve, enhances its sealing performance and stability, and extends the service life of the butterfly valve sealing components.

[0004] To address the aforementioned issues, existing patents offer solutions, but these solutions present the problem of inconvenience in replacing the sealing rings. Traditional methods for replacing valve seals often require disassembling multiple valve components, a complex and time-consuming process that reduces the efficiency of valve seal replacement.

[0005] To address this, a valve seal replacement assembly is proposed. Utility Model Content

[0023] Specifically, such as Figure 4As shown, a plurality of insert rings 8 are provided on the side wall of the gasket 73. The insert rings 8 are movably connected to the mounting holes 72, and one end of the insert ring 8 is located in the middle of the mounting holes 72.

[0024] Specifically, such as Figure 3 As shown, a limiting groove 9 is provided on the side wall of the mounting groove 55, a limiting piece 10 that engages with the limiting groove 9 is fixedly connected to the side wall of the retaining ring 56, a plug 11 is fixedly connected to the side wall of the limiting piece 10, and slots 12 are provided on both sides of the sealing gasket 52, the slots 12 being compatible with the plug 11.

[0025] Specifically, such as Figure 3 As shown, both the connecting flange 61 and the mounting flange 62 have annular grooves 13 on their side walls, and a gasket 14 is provided inside the annular groove 13.

[0026] In use, the valve body 1 has two sealing grooves 51 on its inner wall.

Furthermore, retaining rings 56 are provided in the mounting grooves 55 on both sides of the valve body 1. The retaining rings 56 engage with the limiting grooves 9 via limiting plates 10. Simultaneously, the locking bolt 57 in the center of the retaining ring 56 further enhances the stability of the sealing gasket 52, making the replacement of the sealing gasket 52 simple and quick. Simply loosen the locking bolt 57 to easily remove and replace the sealing gasket 52. An arc-shaped gasket 73 is provided in the groove 71 on the side wall of the valve disc 2. The gasket 73 is fixed in the groove 71 by the positioning bolt 74. The side wall of the gasket 73 is provided with a retaining ring 8, which is movably connected to the mounting hole 72. One end is located in the middle of the mounting hole 72, which increases the contact area and stability between the gasket 73 and the valve disc 2. When the valve is closed, the gasket 73 fits tightly against the valve seat and the sealing gasket 52, which improves the sealing effect between the valve disc 2 and the valve body 1. Through the design of the sealing mechanism 5 and the sealing component 7, it can be ensured that the valve forms a tight seal when closed, effectively preventing media leakage and improving the sealing performance of the valve. The design of the sealing mechanism 5 makes the replacement of the sealing gasket 52 simple and quick, reducing maintenance costs and downtime.

The mounting sleeve 64 has a hexagonal groove 65 in the middle to facilitate connection with a hexagonal rod 66. Limiting components 67 are installed at both ends of the hexagonal rod 66. The limiting components 67 include limiting blocks 671. The limiting block 671 is connected to the locking screw 672 by a thread. The side wall of the locking screw 672 contacts the hexagonal rod 66 to lock it in place. The locking grooves 15 at both ends of the hexagonal rod 66 contact the side wall of the locking screw 672 to further ensure the stability of the position of the hexagonal rod 66, thereby preventing the connection mechanism from loosening or falling off. When replacing the sealing gasket 52, the mounting flange 62 and the connecting flange 61 are disassembled. At this time, the valve body 1 rotates around the hexagonal rod 66 and moves to the bottom of the connecting pipe 4. This process allows the sealing gasket 52 to be replaced. After the replacement is completed, rotating the valve body 1 allows the mounting flange 62 and the connecting flange 61 to quickly align.

[0031] By adopting the above technical solution, the problem of inconvenient replacement of sealing rings in existing butterfly valves has been solved. Traditional valve seal replacement methods often require disassembling multiple valve components, which is a complex, time-consuming, and labor-intensive process, resulting in reduced efficiency in valve seal replacement.

[0032] Working principle: When using this application, the sealing gasket 52 is first placed into the sealing groove 51. The sealing end is fixed by the retaining ring 56 and the locking bolt 57 to achieve quick installation of the sealing gasket 52. The cooperation between the gasket 73 and the positioning bolt 74 achieves quick installation between the gasket 73 and the valve disc 2. The cooperation between the sealing gasket 52 and the gasket 73 achieves efficient sealing of the valve body 1, and at the same time, it achieves efficient disassembly and replacement of the sealing gasket 52 and the gasket 73.
