Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0027] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] In a first aspect, the present application provides a sealing joint conversion part, which will be illustrated below using two embodiments.

[0030] Example 1, see Figure 1 The present embodiment provides a sealing joint conversion part, including a conversion body 1, the middle part of which has a through medium channel 2; the side of the conversion body 1 has a mounting portion 3 extending outward, and the mounting portion 3 has a first bolt hole 4; the first end face of the conversion body 1 has a convex surface 5; the second end face of the conversion body 1 has an annular groove 6; the second end face of the conversion body 1 protrudes from the mounting portion 3, and a shoulder 7 is formed between the second end face of the conversion body 1 and the mounting portion 3.

[0031] The convex surface 5 is used for sealing with the concave surface of the interface flange of the pipeline or pressure equipment. The convex surface 5 and the concave surface together form the FM concave-convex sealing surface after sealing.

[0032] The annular groove 6 is used for sealing cooperation with the annular connection surface of the interface flange of the pipeline or pressure equipment. The annular groove 6 and the annular connection surface together constitute the RJ ring connection sealing surface after sealing cooperation.

[0033] In combination with the above content, it can be seen that the two ends of the sealing joint conversion piece are used to connect to different types of sealing surfaces respectively, solving the connection problem between different types of sealing surfaces of different equipment in a convenient and economical way.

[0034] Example 2, see Figure 1~Figure 2This embodiment is a further improvement made on the basis of Embodiment 1, and is suitable for situations where the pressure is not high and the medium is non-toxic.

[0035] In this embodiment, the sealing joint conversion piece further includes a modification piece 8 detachably connected to the second end face of the adapter body 1, and the modification piece 8 is used to change the sealing surface type of the second end face of the adapter body 1;

[0036] The modified part 8 has a through hole 9 in the middle, and a connecting portion 10 extending outward is provided on the side of the modified part 8 . The connecting portion 10 has a second bolt hole 11 used in conjunction with the first bolt hole 4 .

[0037] In a specific implementation scenario, the second end surface of the modified part 8 has a positioning block 12 that can be engaged with the aforementioned shoulder 7, and the second bolt hole 11 is located on the positioning block 12. The positioning block 12 is engaged with the shoulder 7 to facilitate the positioning between the modified part 8 and the adapter body 1.

[0038] The first end face of the modified part 8 is a plane 13, and the second end face of the modified part 8 is detachably connected to the second end face of the adapter body 1. After the second end face of the modified part 8 is connected to the second end face of the adapter body 1, the modified part 8 and the adapter body 1 are used as a whole, and the second end face of the modified part 8 can be sealed with the plane 13 of the interface flange of the pipeline or pressure equipment, thereby forming a FF full-flat sealing surface together, solving the connection problem between different sealing surfaces of different equipment.

[0039] In a specific implementation scenario, the second end face of the modified part 8 has an annular protrusion 14 matching the annular groove 6 , which not only helps to position the modified part 8 and the adapter body 1 , but also improves the sealing between the modified part 8 and the adapter body 1 .

[0040] In combination with the above content, it can be seen that, compared with Example 1, this embodiment can adapt to the installation requirements of more types of sealing surfaces through the provision of the modified part 8.

[0041] Second, see Figure 1-2 The present application provides a pipeline connected with a sealing joint conversion piece as described in Example 1 or Example 2.

[0042] Thirdly, see Figure 1-2 The present application provides a pressure device connected to a sealing joint conversion piece as described in Example 1 or Example 2.
