DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-5 A double filter valve comprises a pipe 1, the outer sides of both ends of the pipe 1 are rotatably connected with handles 6, ball valve cores 5 are provided in both ends of the pipe 1, and each ball valve core 5 is connected to the handle 6 corresponding in position, a connecting seat 2 is fixed and connected in the pipe 1, a slide seat 3 is slidably connected in the connecting seat 2, handles 4 are fixedly installed on both outer sides of the slide seat 3, a plurality of filtering mechanisms are installed in the slide seat 3, and one of the filtering mechanisms is connected to the pipe 1, a sealing mechanism is provided in the connecting seat 2, and the filtering mechanisms at the corresponding positions are sealed and connected to the pipe 1 through the sealing mechanism, a plurality of card grooves 24 are symmetrically opened on the top surface of the slide seat 3, a limiting mechanism is provided on the top surface of the connecting seat 2, and the output end of the limiting mechanism is carded in the corresponding card groove 24.

[0027] like Figure 1-5 As shown, the specific implementation method is: by setting a handle 6 and a ball valve core 5, the fluid can be closed or released from both ends of the pipeline 1. At the same time, through the connecting seat 2 and the slide seat 3, the slide seat 3 can be slid to make the connecting seat 2 correspond to different filtering mechanisms, thereby conveniently replacing the filtering mechanism. At the same time, the old filtering mechanism is located outside and can be conveniently cleaned or replaced using tools.

[0028] The sealing mechanism includes a drive box 13, and the drive box 13 is fixedly mounted on the top surface of the connecting seat 2. Inflatable sealing rings 12 are embedded on both side walls of the connecting seat 2, and each inflatable sealing ring 12 is against the outer side of the sliding seat 3. A pressure plate 22 is slidably connected inside the drive box 13. The drive box 13 drives the pressure plate 22 to slide through the lifting mechanism. An airbag 21 is fixedly mounted on the bottom wall of the drive box 13. Both outer sides of the airbag 21 are symmetrically fixed and connected with multiple connecting pipes 14, and the multiple connecting pipes 14 located on the same side are all connected to the inflatable sealing rings 12 with corresponding positions.

[0029] The lifting mechanism drives the pressure plate 22 to squeeze the airbag 21, thereby discharging the air in the airbag 21 into the connecting pipe 14, and injecting the gas into the inflatable sealing ring 12 through the connecting pipe 14, causing the inflatable sealing ring 12 to collide, and then filling the gap between the filter mechanism on the sliding seat 3 and the connecting seat 2, thereby achieving sealing.

[0030] The limiting mechanism includes multiple fixed cylinders 15, and the multiple fixed cylinders 15 are symmetrically installed on the top surface of the connecting seat 2. Each fixed cylinder 15 is elastically and slidably connected with a pin 18, and the bottom end of each pin 18 passes through the connecting seat 2 and is locked in the corresponding slot 24.

[0031] A baffle 16 is fixedly mounted on the outside of each fixed cylinder 15 , a spring 17 is fixedly connected to the top surface of each baffle 16 , and the other end of each spring 17 is fixedly connected to the bottom surface of a corresponding bayonet 18 .

[0032] The spring 17 can securely hold the latch 18 in the latch slot 24 , thereby limiting the position of the slide 3 .

[0033] Each filter mechanism includes a connecting tube 9, and each connecting tube 9 is slidably connected to the slide 3. Filter plates 7 are installed at both ends of each connecting tube 9. Each filter plate 7 is fixedly connected to the slide 3 by bolts. A filter element 10 is installed in each connecting tube 9. The filter mechanism can be separated from the slide 3 by tightening the bolts, which is convenient for quick processing.

[0034] The lifting mechanism includes a threaded rod 19 , and the threaded rod 19 is threadedly connected to the top surface of the driving box 13 , and the bottom end of the threaded rod 19 is rotatably connected to the pressure plate 22 , and a knob 20 is installed on the top surface of the threaded rod 19 .

[0035] It is worth noting that the thread is self-locking, and thus when the threaded rod 19 stops rotating, the position of the pressure plate 22 is fixed.

[0036] The top and bottom walls of the connecting seat 2 are both provided with a plurality of slide grooves 11 , and the top surface and the ground of the slide seat 3 are both fixedly mounted with sliders 23 , and each slider 23 is slidably connected in the corresponding slide groove 11 to enhance the sliding stability of the slide seat 3 .

[0037] When the present invention is in use, when the filter mechanism connected to the connecting seat 2 needs to be replaced, the handles 6 on both sides can be turned to rotate the ball valve core 5 to close the two ends of the pipe 1, and then the knob 20 is turned in the opposite direction to drive the threaded rod 19 to rotate, thereby driving the pressure plate 22 to slide upward, and then the air bag 21 itself deforms and expands, and the air in the inflatable sealing ring 12 is extracted, and then the limit of the slide seat 3 is released by pulling the latch 18 upward, and then the slide seat 3 can be pulled by the handle 4 to replace the filter mechanism connected to the connecting seat 2 and replace it with the filter mechanism on the left or right side, and then the mounting plate 8 is loosened to limit the slide seat 3, and the knob 20 is turned forward to expand the inflatable sealing ring 12 again, so that the connecting seat 2 and the slide seat 3 are sealed;

[0038] At the same time, the pulled-out filter mechanism is now exposed to the outside world, making it convenient to take the filter plate 7 and the connecting tube 9 out of the slide seat 3 by means of tools. At the same time, the filter plate 7 and the filter element 10 facilitate coarse and fine filtration of the fluid medium, thereby increasing the filtration effect, and then replacing it with a new filter mechanism.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
