DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4 As shown, the utility model provides an anti-clogging stainless steel ball valve casting, including a body 1, both sides of the body 1 are fixedly connected with a first connecting flange 11, one side of the first connecting flange 11 is provided with a second connecting flange 12, the side of the second connecting flange 12 away from the first connecting flange 11 is provided with a third connecting flange 13, the second connecting flange 12 and the third connecting flange 13 are fixedly connected with a first connecting pipe 14 on the opposite inner sides, a connecting plate 15 is fixedly installed between the two first connecting pipes 14, one side of the connecting plate 15 is provided with a placement groove 10, the interior of the placement groove 10 is provided with a filter plate 16, and the third connecting flange 13 is provided with a filter plate 16. A fourth connecting flange 18 is provided on the side away from the connecting plate 15, and a second connecting pipe 19 is fixedly installed on the side of the fourth connecting flange 18 away from the third connecting flange 13. By setting the filter plate 16, impurities in the fluid entering from the second connecting pipe 19 are filtered, and the particle impurities are directly adsorbed on the filter plate 16, thereby preventing the impurities from blocking the stainless steel ball valve and affecting the use of the stainless steel ball valve. A second handle 5 is fixedly installed on one side of the filter plate 16. By setting the second handle 5, it is more convenient to take the filter plate 16 out of the placement groove 10, clean the impurities adsorbed on the filter plate 16, and replace or repair the filter plate 16;

[0018] Two symmetrically distributed fixing blocks 3 are fixedly installed on the top of the connecting plate 15, a circular groove 31 is provided at the bottom end of the fixing block 3, a spring 32 is fixedly installed on the lower surface of the inner wall of the circular groove 31, a fixing column 33 is fixedly installed at the bottom end of the spring 32, a connecting rod 34 is fixedly installed on the top of the fixing column 33, a first handle 35 is rotatably sleeved on the top of the connecting rod 34, a fixing groove 36 used in conjunction with the fixing column 33 is provided on the top of the filter plate 16, the connecting rod 34 is located inside the spring 32, and the connecting rod 34 is slidably stuck in the fixing block 3 and the connecting plate 15, by setting the fixing column 33 and the fixing groove 36, when the first handle 35 is rotated in the direction of the third connecting flange 13, the connecting rod 34 and the fixing column 33 are driven to move upward, the spring 32 contracts, and the fixing column 33 is separated from the corresponding fixing groove 36;

[0019] When the first handle 35 and the corresponding fixing block 3 are in a vertical straight shape, it means that the fixing column 33 is completely separated from the corresponding fixing groove 36, and the filter plate 16 can be taken out from the placement groove 10. When the first handle 35 is rotated in the opposite direction, the connecting rod 34 and the fixing column 33 are driven to move downward, and the spring 32 rebounds, so that the fixing column 33 is stuck in the corresponding fixing groove 36. When the first handle 35 and the fixing block 3 are in a seven-shaped shape, it means that the fixing column 33 is completely stuck in the fixing groove 36, and the filter plate 16 is fixed in the connecting plate 15, so as to facilitate the installation, disassembly, cleaning and replacement of the filter plate 16. The first handle 35 is made of plastic, which increases the comfort between the hand and the first handle 35 and makes it easier to rotate the first handle 35.

[0020] Positioning plates 2 are fixedly mounted on the opposite inner sides of the first connecting flange 11 and the fourth connecting flange 18 , and positioning grooves 21 for use with the positioning plates 2 are formed through the tops of the third connecting flange 13 and the second connecting flange 12 .

[0021] The second connecting flange 12 and the third connecting flange 13 are both fixedly installed with a fixing seat 4 on the opposite inner sides. The middle part of the fixing seat 4 is threadedly connected with a threaded rod 41. The bottom end of the threaded rod 41 is fixedly installed with a clamping column 42. The top of each positioning plate 2 is penetrated by a clamping groove 43 used in conjunction with the clamping column 42. By setting the threaded rod 41, when the threaded rod 41 rotates, the clamping column 42 is driven to rotate. The threaded connection between the threaded rod 41 and the fixing seat 4 causes the clamping column 42 to slowly move downward and be clamped into the corresponding clamping groove 43, so that the first connecting flange 11 and the second connecting flange 12 and the third connecting flange 13 are connected. The flange 13 and the fourth connecting flange 18 are fixed together, so as to facilitate the bolt connection between the first connecting flange 11 and the second connecting flange 12 and the third connecting flange 13 and the fourth connecting flange 18. A rotating wheel 44 is fixedly installed on the top of each threaded rod 41, and a plurality of annular and evenly distributed anti-slip strips are fixedly installed on the outside of the rotating wheel 44. By setting the rotating wheel 44, when the rotating wheel 44 is rotated, the threaded rod 41 is driven to rotate, thereby driving the clamping column 42 to rotate. At the same time, by setting the protective strip, the friction between the hand and the rotating wheel 44 is increased, so that it is more convenient to rotate the rotating wheel 44.

[0022] Working principle: When in actual use, insert the filter plate 16 into the placement groove 10, then turn the first handle 35 in the opposite direction of the third connecting flange 13, drive the connecting rod 34 and the fixing column 33 to move downward, and at the same time, the spring 32 rebounds, so that the fixing column 33 is stuck in the corresponding fixing groove 36. When the first handle 35 and the fixing block 3 are in a seven-character shape, it means that the fixing column 33 is completely stuck in the fixing groove 36, so that the filter plate 16 is fixed in the connecting plate 15. Then, during the use of the stainless steel ball valve, impurities are directly blocked by the filter plate 16 and adsorbed on the filter plate 16. Then, the filter plate 16 is taken out from the connecting plate 15 regularly for cleaning;

[0023] When the first connecting flange 11 and the second connecting flange 12 as well as the third connecting flange 13 and the fourth connecting flange 18 need to be fixed together, firstly insert the positioning plate 2 on the first connecting flange 11 and the positioning plate 2 on the fourth connecting flange 18 into the corresponding positioning grooves 21 on the second connecting flange 12 and the third connecting flange 13, then correspond the bolt holes on the first connecting flange 11 and the second connecting flange 12 as well as the third connecting flange 13 and the fourth connecting flange 18, and then use bolts to fix the first connecting flange 11 and the second connecting flange 12 together as well as the third connecting flange 13 and the fourth connecting flange 18 together.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
