Technical Field

[0001] The utility model relates to the technical field of window flanges, in particular to a window flange. Background Art

[0002] Window flange generally refers to flange sight glass, and because it is two flanges clamped together, it is also called clamped sight glass. It is suitable for chemical, petroleum, cosmetics, medicine and other industrial equipment to observe the material operation status inside the equipment and prevent accidents.

[0003] In actual work, the structure and function of the window flange in the prior art are relatively complete and can basically meet the needs of daily use, but there are still the following problems:

[0004] In actual use, since the flange sight glass is directly connected to the reaction chamber inside the industrial equipment, the high temperature and corrosiveness of the internal reactants during the reaction process will corrode the glass, thereby reducing the service life of the glass. In addition, the installation and connection structure of the window flange uses a large number of bolts. In order to ensure the sealing, the glass of the flange sight glass will be bonded to a flange, and then holes will be punched on it for auxiliary fixation. The entire installation process is very cumbersome.

[0005] Therefore, the utility model provides a window flange. Utility Model Content

[0024] 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.

[0025] like Figure 1-Figure 4As shown, this embodiment provides a technical solution: a window flange, including an upper flange 1 and a lower flange 2, the inner wall of the upper flange 1 is fixedly connected with a first annular block 3, one side of the first annular block 3 is provided with a first sealing ring groove 4, and the inner wall of the first sealing ring groove 4 is clamped with a first sealing ring 5; the inner wall of the lower flange 2 is fixedly connected with a second annular block 8, one side of the second annular block 8 is provided with a second sealing ring groove 10, and the inner wall of the second sealing ring groove 10 is clamped with a second sealing ring 7; a window glass 6 is clamped between the upper flange 1 and the lower flange 2, the inner wall of the lower flange 2 is provided with a first threaded hole 11, the inner wall of the first threaded hole 11 is threadedly connected with a hexagon socket head screw 12, and the inner wall of the upper flange 1 is provided with a first threaded hole 11. A second threaded hole 13 is opened on the wall, and the hexagon socket cylindrical head screw 12 is detachably threadedly connected to the second threaded hole 13; a protective limiting structure 9 is arranged on one side of the lower flange 2, and by arranging the first sealing ring 5, the second sealing ring 7 and the window glass 6, the hexagon socket cylindrical head screw 12 allows the window glass 6 to be directly installed between the upper flange 1 and the lower flange 2 during the fixing process, without the need to separately arrange a mounting structure to install and seal the window glass 6, thereby saving installation time and improving installation efficiency. At the same time, under the action of quartz glass and fluororubber materials, the sealing performance of the window glass 6 and the first sealing ring 5 and the second sealing ring 7 can be improved, which is very practical.

[0026] Further, such as Figure 1-Figure 3 As shown: the diameter of the window glass 6 is larger than the diameter of the first annular block 3 and smaller than the diameters of the upper flange 1 and the lower flange 2, the window glass 6 is quartz glass, the first sealing ring 5 and the second sealing ring 7 are fluororubber sealing rings, the number of the first threaded hole 11, the second threaded hole 13 and the hexagon socket head screw 12 are the same, and the outer surfaces of the upper flange 1 and the lower flange 2 are both provided with reserved circular holes. Under the action of the upper flange 1 and the lower flange 2, the first sealing ring 5 and the second sealing ring 7 can be cooperated to make the upper flange 1 and the lower flange 2 and the window glass 6 be auxiliary fixed, and then the upper flange 1 and the lower flange 2 can be fixed by the hexagon socket head screw 12, so that the overall installation steps are simplified, and at the same time, the materials of quartz glass and fluororubber can improve the overall corrosion resistance and high temperature resistance.

[0027] The above solution also has the problem that after the window glass 6 explodes, splashing will cause safety hazards, such as Figure 3 and Figure 4As shown: in the present scheme, the protective limiting structure 9 includes an annular frame 91, one side of the outer surface of the annular frame 91 is fixedly connected to one side of the lower flange 2, the inner wall of the annular frame 91 is clamped with an annular clamping block 92, one side of the outer surface of the annular clamping block 92 is fixedly connected to an auxiliary ring block 93, the inner wall of the auxiliary ring block 93 is fixedly connected to a circular glass block 94, the inner wall of the circular glass block 94 is rotatably connected to a rotating round rod 95, one end of the rotating round rod 95 is fixedly connected to an operating round block 96, and the outer surface of the operating round block 96 is rotatably connected to a perforated circular plate 97. By arranging the annular clamping block 92 and the annular frame 91, the annular clamping block 92 and the circular glass block 94 can be auxiliary installed, and then the perforated circular plate 97 can be auxiliary installed. When the internal quartz glass bursts, the entire device can prevent it from splashing to the surrounding area and injuring people under the action of structures such as the perforated circular plate 97, and at the same time, the internal situation can be observed through the circular glass block 94.

[0028] The above solution still has the problem that the friction fixation between the annular frame 91 and the annular clamping block 92 is not stable and is easy to be separated. Figure 3 and Figure 4 As shown, four circular clamping rods 98 are fixedly connected to one side of the outer surface of the perforated circular plate 97 at equal intervals, a circular clamping hole 99 is opened on one side of the outer surface of the second annular block 8, and the circular clamping rods 98 can be clamped into the inner wall of the circular clamping hole 99, one end of the rotating circular rod 95 is fixedly connected to a rotating plate 910, the outer surface of the rotating plate 910 is fixedly connected to an arc block 911, and the inner arc surface of the second annular block 8 is fixedly connected to an arc stopper 912. By setting the rotating plate 910 and the arc block 911, the arc stopper 912 can be cooperated to make the circular glass block 94 and the perforated circular plate 97 and other components auxiliary fixed to the lower flange 2 to avoid separation due to a large impact.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use: fix the first sealing ring 5 to the first sealing ring groove 4, fix the second sealing ring 7 to the second sealing ring groove 10, place the window glass 6 between the upper flange 1 and the lower flange 2, fit the upper flange 1 and the lower flange 2 together, and fix the hexagon socket head cap screw 12 to the first threaded hole 11 and the second threaded hole 13 for auxiliary fixing;

[0032] At this time, the annular clamping block 92 is fixed to the annular frame 91, and the circular clamping rod 98 can be fixed to the circular clamping hole 99, so that when the window glass 6 explodes, the fragments can be prevented from flying;

[0033] The rotating rod 95 is operated so that the rotating rod 95 can drive the rotating plate 910 to rotate, and then drive the arc block 911 to rotate, so that the arc block 911 can fit with the arc stopper 912, thereby preventing the auxiliary ring block 93 and other components from being separated from the annular frame 91.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
