A sealed flange includes an upper flange and a lower flange. Four circumferentially distributed threaded holes are drilled on both the upper flange and the lower flange. Bolts are threadedly connected in the threaded holes, and nuts are threadedly connected to both the upper and lower ends of the bolts. The upper flange and the lower flange are both drilled with pipe connection holes located on the same axis. Four circumferentially distributed arc-shaped connecting rods are fixedly connected to the lower end of the upper flange, and the central axis of the arc-shaped connecting rod is located on the central connection line between the adjacent threaded holes and the pipe connection holes. An arc-shaped clamping block is fixedly connected between two adjacent arc-shaped connecting rods, and the arc-shaped clamping block is located exactly in the middle of two adjacent threaded holes. The lower flange is drilled with an installation arc-shaped groove matching the arc-shaped clamping block at the corresponding position, which can improve the sealing effect of flange connection and weaken the radial runout existing between the flange plates;

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7 , the present invention provides the following technical solutions.

[0032] Embodiment 1: To solve the problem that in the prior art, only a sealing ring is used to seal between the connected flanges, and the sealing effect will decline during long-term use. Therefore, in this embodiment, through the following technical solutions, a water and gas sealing type flange is provided with a flange body 1, a flange hole 2, a long air pipe interface 3 and a short interface 4. Sealing rings are arranged between the flange bodies 1 at the left and right ends in a fitting manner, and multiple groups of flange holes 2 are opened at the edge of the flange body 1. Two groups of long air pipe interfaces 3 are respectively arranged at the front and rear ends of the flange body 1, and two groups of short interfaces 4 are arranged at the lower end of the flange body 1. As Figure 1 and Figure 4 shown, through the settings of the long air pipe interface 3, the short interface 4 and the sealing ring, a good sealing effect can be achieved between the flange bodies 1 at the left and right ends.

[0033] Embodiment 2: In the existing water and gas sealing type flanges, when assembling and connecting the flanges, bolts are mostly used for connection and fixation. The bolts may become loose after long-term use, which will affect the stability of the assembly connection between the flanges. Therefore, by setting a fixed connection column 5, a fixed connection rod 6 and a fixed connection cap 7, a fixed connection rod 6 penetrates through the middle of the corresponding flange hole 2, and the fixed connection cap 7 is arranged in a fitting manner at the edge of the flange body 1. The fixed connection cap 7 is threadedly connected to the outer surface of the fixed connection rod 6 for connection. As Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, when the flange bodies 1 at the left and right ends are butted against each other, the fixed connection column 5 drives the fixed connection rod 6 to be inserted into the flange holes 2 at corresponding positions. Then, by rotating the fixed connection cap 7 threadedly connected to the outer surface of the fixed connection rod 6, the fixed connection cap 7 is closely attached to the flange body 1, thereby facilitating the positioning between the flange bodies 1 at the left and right ends.

[0034] Embodiment 3: For the existing water and gas sealed flange, it is not convenient to lock between the flanges. Therefore, by providing a limiting mechanism 8, the limiting mechanism 8 is symmetrically arranged on the left and right sides of the fixed connection column 5, and the fixed connection column 5 and the limiting mechanism 8 are equally angularly arranged at the edge of the flange body 1. The fixed connection block 9 is fixedly connected to the flange body 1, and the fixed connection block 9 is snap-fitted into the fixed connection groove 11. The diameter dimension of the fixed connection block 9 is smaller than the opening dimension of the fixed connection groove 11 on the side close to the fixed connection column 5. The fixed connection plate 10 is closely attached to the fixed connection cap 7, and the end of the fixed connection plate 10 far from the fixed connection column 5 is penetrated and connected to the fixed connection rod 6. The fixed connection plate 10 and the flange body 1 are limited by a fastening bolt 12. As Figure 1 、 Figure 5 、 Figure 6 and Figure 7 shown, after the fixed connection cap 7 is threadedly connected to the outer surface of the fixed connection rod 6, the fixed connection plate 10 is sleeved outside the fixed connection block 9. At the same time, the end of the fixed connection plate 10 far from the fixed connection column 5 is snap-fitted with the fixed connection rod 6. After the fixed connection block 9 is inserted into the fixed connection groove 11, the fixed connection plate 10 is pushed towards the side close to the fixed connection column 5. The fixed connection plate 10 and the fixed connection rod 6 slide relative to each other. At the same time, the fixed connection block 9 is snap-fitted into the fixed connection plate 10, so that the fixed connection plate 10 and the fixed connection cap 7 are in a fitting arrangement. Then, the fixed connection plate 10 and the flange body 1 are limited by the fastening bolt 12. Through the setting of the fixed connection plate 10, the fixed connection cap 7 can be locked to prevent the fixed connection cap 7 from loosening during long-term use, thereby improving the stability of the butt joint installation between the flange bodies 1.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
