[0021] Reference Figure 1-3 A quick-connect and disassemble marine valve filter device includes a valve body 1, flanges 2 on both sides of the valve body 1, a valve stem 3 extending through the upper end of the valve body 1, an installation groove 8 on the side wall of the right flange 2, an installation ring 4 on the right side of the right flange 2, the installation ring 4 cooperating with the installation groove 8, a filter screen 7 inside the installation ring 4, a positioning mechanism for positioning the installation ring 4 inside the installation groove 8, the positioning mechanism including multiple circumferentially arranged fixing posts 10 arranged in the installation groove 8, and multiple circumferentially arranged waist grooves 5 that cooperate with the fixing posts 10 on the installation ring 4, the waist grooves 5 being arc-shaped.

[0022] A sealing mechanism is provided between the mounting groove 8 and the mounting ring 4 to seal both. The sealing mechanism includes a sealing groove 9 opened in the mounting groove 8 and a sealing ring 6 on the side wall of the mounting ring 4 that cooperates with the sealing groove 9. By placing the mounting ring 4 in the mounting groove 8, the sealing ring 6 on the side wall of the mounting ring 4 is located in the sealing groove 9, thereby achieving a seal between the mounting ring 4 and the mounting groove 8 and improving the sealing performance of the installation.

[0023] Multiple fixed columns 10 have through grooves 11 on their outer walls, and multiple through grooves 11 and the outer walls of fixed columns 10 have mating grooves 12.

[0024] Multiple waist grooves 5 are rotatably connected to rotating columns 13 on their inner walls. The rotating columns 13 cooperate with the through grooves 11. By causing the rotating columns 13 to drive the clamping plate 14 to rotate, the clamping plate 14 and the mating groove 12 are in an interlaced state, thereby limiting the position of the fixed column 10 and the rotating column 13, achieving a stable connection between the mounting ring 4 and the mounting groove 8, and enabling the quick installation and removal of the filter screen 7, bringing certain convenience to people.

[0025] Each of the multiple rotating columns 13 has a retaining plate 14 at its end. The retaining plate 14 cooperates with the mating groove 12. Both the retaining plate 14 and the mating groove 12 are elliptical in shape.

[0026] When using this invention, during the installation of the filter screen 7, the mounting ring 4 is placed in the mounting groove 8, so that the sealing ring 6 on the side wall of the mounting ring 4 is located in the sealing groove 9, thereby achieving a seal between the mounting ring 4 and the mounting groove 8 and improving the sealing performance of the installation. At this time, multiple fixing posts 10 are located in multiple waist grooves 5 respectively. Rotating the mounting ring 4 causes the fixing posts 10 to move within the waist grooves 5, thus allowing multiple rotating posts 13 to pass through the through groove 11. When the fixing posts 10 contact the other end of the waist groove 5, the rotating posts 13 are in place. At this time, rotating the multiple rotating posts 13 causes the rotating posts 13 to drive the clamping plate 14 to rotate, so that the clamping plate 14 and the mating groove 12 are in an interlaced state, thereby limiting the fixing posts 10 and the rotating posts 13, achieving a stable connection between the mounting ring 4 and the mounting groove 8, and achieving quick installation and disassembly of the filter screen 7, bringing certain convenience to people.
