Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a large-diameter stainless steel flange. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as gearbox flanges. In many areas of modern industry, large-diameter reaction vessels, vacuum containers, etc., are required, and large-diameter flanges are necessary in all these applications.

[0003] A search revealed that patent application number 202022152173.9 discloses a large-diameter flange, comprising a flange body, two support modules, and a filter plate; annular connecting portions are provided on both end faces of the flange body; a plurality of first threaded through holes are provided at equal intervals on the end faces of the flange body, the plurality of first threaded through holes penetrating the flange body and the annular connecting portions on the end faces of the flange body; two annular support portions are provided on the outer side face of the flange body; a support ring is provided on the inner wall of the flange body; two support modules are respectively disposed on both sides of the flange body; the two support modules include two studs and support columns; nuts are provided at the ends of the two studs, and the two studs are horizontally fixed to the two annular support portions by the two nuts at the ends; the support columns are respectively sleeved on the two studs. This utility model discloses a large-diameter flange. Two support modules provide excellent support during installation, facilitating installation. An internal filter screen is detachably fixed within the flange body for filtration. While the aforementioned application achieves filtration, support, and ease of installation through the arrangement of various components, the assembly of the two flange sets still uses a contact-type assembly, resulting in a complex structure. This not only makes operation cumbersome but may also lead to leakage at the contact points, especially with some large-diameter flanges, where the probability of leakage is higher. The overall connection effect needs improvement.

[0004] Therefore, we propose a large-diameter stainless steel flange. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a large-diameter stainless steel flange, which solves the problem of fluid leakage caused by existing contact-type conductive flanges.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a large-diameter stainless steel flange, including a left flange and a right flange positioned opposite each other, and both the left flange and the right flange are provided with flow holes for fluid to pass through in the middle.

[0007] The left flange contact surface has a probe at its center, and the right flange contact surface has a probe groove at its center that matches the specifications of the probe. When the left flange and the right flange are assembled, the probe extends into the inside of the probe groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a large-diameter stainless steel flange, including a left flange 1 and a right flange 2 positioned opposite each other, and both the left flange 1 and the right flange 2 are provided with flow holes for fluid to pass through in the middle; a probe 14 is provided at the center of the contact surface of the left flange 1, and a probe groove 24 adapted to the specifications of the probe 14 is provided at the center of the contact surface of the right flange 2, and when the left flange 1 and the right flange 2 are assembled, the probe 14 probes into the inside of the probe groove 24;

[0027] The large-diameter stainless steel flange, through the protrusion 14 and protrusion groove 24 between the left flange 1 and the right flange 2, can increase the interlocking effect between them during assembly. The protrusion assembly method can minimize the risk of leakage and increase the fluid guiding effect. At the same time, it is simple to operate and suitable for efficient disassembly and assembly. Furthermore, the small gap of the contact surface further reduces the risk of leakage and solves the problem that the existing contact conduction method is prone to fluid leakage.

[0028] Example 2:

[0029] The probe 14 is a bucket-shaped end tube, and the probe groove 24 is a bucket-shaped cylindrical groove that matches the shape of the probe 14. When the probe 14 and the probe groove 24 are engaged, a sealing sleeve is pressed between them. The shape of the probe 14 and the probe groove 24 facilitates the engagement between them during assembly to achieve probe-type conduction. With the engagement of the sealing sleeve between them, the conduction effect between the fluid inside can be guaranteed, which can maximize the avoidance of leakage and achieve the effect of efficient connection.

[0030] The left flange 1 has a locking groove 13 located outside the probe 14 on the contact surface, and the right flange 2 has a locking part 23 located outside the probe 24 fixedly installed on the contact surface. When the left flange 1 and the right flange 2 are assembled, the locking part 23 is locked inside the locking groove 13. The locking groove 13 and the locking part 23 can increase the locking fit between the left flange 1 and the right flange 2, reduce the gap when they are in contact, and further increase the assembly sealing.

[0031] A liquid inlet clamp 12 is fixedly installed at the center of the outer end face of the left flange 1, and a liquid outlet clamp 22 is fixedly installed at the center of the outer end face of the right flange 2. The left flange 1 and the right flange 2 are respectively connected to the input pipe group and the output pipe group through the liquid inlet clamp 12 and the liquid outlet clamp 22. The setting of the liquid inlet clamp 12 and the liquid outlet clamp 22 facilitates the connection of the left and right input pipe groups and the output pipe groups, ensuring the connection effect.

[0032] The left flange 1 and the right flange 2 have eight sets of left threaded holes 11 and right threaded holes 21 with opposite positions on the inner side of their annular edges. The left threaded holes 11 and right threaded holes 21 are provided to assist the fastening bolts in pressing them together to ensure the immersion assembly effect.

[0033] The left threaded hole 11 and the right threaded hole 21 on the left flange 1 and the right flange 2 are assembled by fastening bolts. When the fastening bolts are screwed into the left threaded hole 11 on the left flange 1 and the right threaded hole 21 on the right flange 2, a sealing sleeve is pressed between them. The setting of the fastening bolts and the sealing sleeve makes it easy to use the fastening bolts to press and seal them, ensuring the assembly is airtight.

[0034] The working principle and usage process of this utility model are as follows: When the device is required to work, the contact surface of the left flange 1 is engaged with the contact surface of the right flange 2. At this time, the protrusion part 14 is inserted into the inner side of the protrusion groove 24, and a sealing sleeve is pressed between them. Then, according to the requirements, the left flange 1 and the right flange 2 are pressed together with each set of fastening bolts. The engagement between the engagement groove 13 and the engagement part 23 can achieve a seamless assembly effect, ensuring the assembly effect.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
