[0002] Flange gland, flange cover, some are also called blind flange or pipe plug. It is a flange without a hole in the middle, used to seal the pipe opening. The function is the same as that of the head and the pipe cap, except that the blind plate seal is a detachable sealing device, while the seal of the head is not intended to be opened again. There are many types of sealing surfaces, including flat surface, convex surface, concave-convex surface, tongue-and-groove surface and ring connection surface. The materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR, etc., and are often used in metallurgical production.

[0003] In metallurgical production, flange glands are usually used in conjunction with flanges to seal pipe ports. However, existing flange glands and flanges are generally connected and fixed with a large number of bolts, which makes the installation and removal of flange glands cumbersome, time-consuming and labor-intensive.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] See also Figure 1-4 The utility model provides a flange gland for metallurgical production, comprising a flange body 1, a flange cover 2 and a connecting assembly 3 for connecting the flange body 1 and the flange cover 2. A plurality of connecting holes 11 are provided at the edge of the flange body 1, a plurality of connecting columns 21 adapted to the connecting holes 11 are fixedly connected to the edge of the flange cover 2, a locking groove 12 is provided on the inner wall of the connecting hole 11, a groove 22 is provided inside the connecting column 21, and the connecting assembly 3 is arranged in the groove 22. When installing the flange cover 2, the connecting column 21 of the flange cover 2 needs to be aligned with the connecting hole 11 of the flange body 1 and inserted so that the flange body 1 and the flange cover 2 are butted together.

[0023] Specifically, the connecting assembly 3 includes a U-shaped block 31, a locking block 32, a support plate 33 and a spring 34. The U-shaped block 31 is slidably connected in the groove 22. The locking block 32 is slidably installed on both sides of the U-shaped block 31. The end of the locking block 32 away from the U-shaped block 31 is provided with an oblique angle. The support plate 33 is fixedly connected in the groove 22. The spring 34 abuts between the support plate 33 and the U-shaped block 31. Both sides of the U-shaped block 31 are provided with obliquely arranged guide holes 35. Both sides of the locking block 32 are fixedly connected with guide blocks 36. The guide blocks 36 slide in the guide holes 35. By setting the connecting assembly Part 3, during the process of inserting the connecting column 21 into the connecting hole 11, the locking block 32 will be forced to retract into the groove 22. After the connecting column 21 is fully inserted into the connecting hole 11, the locking block 32 can be reset by using the spring 34, so that the locking block 32 is inserted into the locking groove 12, and the flange cover 2 can be installed. When disassembling, just press the U-shaped block 31, squeeze the guide block 36 through the guide hole 35 on the U-shaped block 31, so that the guide block 36 drives the locking block 32 to retract into the groove 22, and the flange cover 2 can be opened, which is convenient for the installation and disassembly of the flange cover 2, without the need to use bolts, saving time and effort.

[0024] In order to ensure the stability of the U-shaped block 31, a limiting groove 23 is provided on the inner wall of the groove 22, and limiting blocks 37 are fixedly connected on both sides of the U-shaped block 31. The limiting blocks 37 slide in the limiting groove 23, which can limit the U-shaped block 31, so that the U-shaped block 31 can slide stably in the groove 22, and prevent the U-shaped block 31 from detaching from the groove 22.

[0025] In order to improve the sealing performance of the flange cover 2, a protrusion 24 is provided on the inner surface of the flange cover 2, and a first sealing ring 25 is abutted between the outer circumference of the protrusion 24 and the inner wall of the flange body 1. A convex ring 26 is provided on the inner surface of the flange cover 2. An annular groove 13 is opened on the end surface of the flange body 1. The convex ring 26 is inserted into the annular groove 13, and a second sealing ring 27 is abutted between the convex ring 26 and the inner wall of the annular groove 13. When installing the flange cover 2, the protrusion 24 is inserted into the center hole of the flange body 1, and the convex ring 26 is inserted into the annular groove 13. The flange body 1 is sealed by the first sealing ring 25 and the second sealing ring 27 to improve the sealing effect of the flange cover 2.

[0026] The working principle and use process of the utility model are as follows: first, when installing the flange cover 2, the connecting column 21 of the flange cover 2 needs to be aligned with the connecting hole 11 of the flange body 1 and inserted so that the flange body 1 and the flange cover 2 are butted together. In the process of inserting the connecting column 21 into the connecting hole 11, the locking block 32 will be forced to retract into the groove 22. After the connecting column 21 is fully inserted into the connecting hole 11, the locking block 32 can be reset by the spring 34 so that the locking block 32 is inserted into the locking groove 12, and the flange cover 2 can be installed. When disassembling, it is only necessary to press the U-shaped block 31 and squeeze the guide block 36 through the guide hole 35 on the U-shaped block 31 so that the guide block 36 drives the locking block 32 to retract into the groove 22, and the flange cover 2 can be opened, which is convenient for the installation and disassembly of the flange cover 2. There is no need to use bolts, which saves time and effort.
