Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the presence of multiples. Unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple sets" means two or more (including two sets).

[0023] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

[0025] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a sealing structure for a housing end flange, including a first flange 1; a second flange 2 is provided on the right side of the first flange 1, and a liquid blocking ring 3 is fixedly connected to the right side of the first flange 1. An annular groove 4 is provided on the side wall of the liquid blocking ring 3, and a liquid retaining ring 5 is provided in the annular groove 4. The other end of the liquid retaining ring 5 is fixedly connected to the side wall of the second flange 2. A liquid sealing ring 6 is sleeved on the liquid blocking ring 3, and the other end of the liquid sealing ring 6 is fixedly connected to the side wall of the second flange 2. A connecting mechanism is provided on the first flange 1 and the second flange 2.

[0028] In the technical solution of this application embodiment, the sealing tube 7 and the conical groove are arranged so that the sealing tube 7 fits against the inner wall of the second flange 2, thereby improving the sealing performance of the connection between the first flange 1 and the second flange 2. The sealing tube 7 is fixedly connected to the inner wall of the first flange 1, and the conical groove is opened on the inner wall of the second flange 2. The right end of the sealing tube 7 matches the inner wall of the conical groove. The connection mechanism facilitates the connection between the first flange 1 and the second flange 2. The connection mechanism includes a number of bolts 8. Each bolt 8 passes through the round hole on the first flange 1 and the second flange 2, and a pair of transmission rings 9 are sleeved on each bolt 8. A spring 10 is fixedly connected between each pair of transmission rings 9. The spring 10 is sleeved on the bolt 8, and a nut 11 is threadedly connected to each bolt 8.

[0029] In the technical solution of this application embodiment, the first flange 1 and the second flange 2 are more easily disassembled by the rotating block 12 and the L-shaped block 13. Each bolt 8 is fixedly connected to the rotating block 12, and each nut 11 is fixedly connected to the L-shaped block 13. Each rotating block 12 is provided with anti-slip texture, and each L-shaped block 13 is provided with anti-slip texture on its outer wall. Several bolts 8 are arranged in a ring about the central axis of the first flange 1 and the second flange 2.

[0030] Working principle: In use, the first flange 1 and the second flange 2 are both welded to the end of the annular shell. When it is necessary to connect the first flange 1 and the second flange 2, simply insert the liquid-blocking ring 5 into the annular groove 4 and make the liquid-sealing ring 6 fit on the liquid-blocking ring 3. Thus, through the interlocking action of the liquid-blocking ring 3, the annular groove 4 and the liquid-sealing ring 6, the sealing performance between the first flange 1 and the second flange 2 is improved. At the same time, the sealing tube 7 is inserted into the second flange 2. Then, hold the rotating block 12 and tighten the nut 11 through the L-shaped block 13. The nut 11 pushes the transmission ring 9 to move, thereby squeezing the second flange 2 through the spring 10, so that the second flange 2 is sealed and fitted against one end of the sealing tube 7, thereby improving the sealing performance of the connection between the first flange 1 and the second flange 2. When it is necessary to disassemble the first flange 1 and the second flange 2, hold the rotating block 12 and unscrew the nut 11 through the L-shaped block 13 to disassemble the first flange 1 and the second flange 2.
