Description

Technical Field

[0001] This utility model relates to the field of end cap technology, specifically a double-layer spherical end cap. Background Technology

[0002] Spherical heads, also known as spherical crown heads, are heads formed by the spherical crown portion of a spherical shell. Due to their excellent performance and wide range of applications, spherical heads play an important role in industrial production.

[0003] Chinese patent (authorization announcement number: CN 202531829 U, authorization announcement date: 2012.11.14) proposes a spherical end cap, which includes an end cap body, the cross-section of which is a semi-annular structure. This utility model of a spherical end cap has a wide range of applications.

[0004] However, the aforementioned spherical head only has a single-layer sealing effect, resulting in poor thermal insulation performance. To improve the thermal insulation performance of the head, we propose a double-layer spherical head. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-layer spherical end cap. By employing an inner and outer end cap design, and fixing the inner and outer end caps together with a base, a cavity is formed between the inner and outer end caps. This effectively isolates the heat exchange between the inside and outside of the end cap, greatly improving its thermal insulation effect and solving the problems mentioned earlier.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-layer spherical end cap includes a mounting base on which an inner end cap and an outer end cap are fixedly mounted. The inner end cap is fitted inside the outer end cap. A first mating ring is integrally mounted on the bottom of the outer end cap, and a second mating ring is integrally mounted on the bottom of the inner end cap. The mounting base has a first annular groove and a second annular groove, wherein the first annular groove and the first mating ring are mutually engaged, and the second annular groove and the second mating ring are mutually engaged.

[0008] Preferably, a limiting block is fixedly installed inside the outer end cap, and a limiting groove is formed on the limiting block. A limiting protrusion is fixedly installed on the outer surface of the inner end cap, and the limiting protrusion and the limiting groove cooperate with each other.

[0009] Preferably, both the inner and outer end caps are provided with through holes, and a pressure gauge is installed in the through holes, with the probe of the pressure gauge extending into the inner end cap.

[0010] Preferably, a plurality of support strips are fixedly installed on the outer surface of the inner end cap, and the support strips are in close contact with the inner surface of the outer end cap.

[0011] Preferably, a sealing ring is fixedly embedded at the bottom of the mounting base.

[0012] Preferably, a cavity is formed between the inner and outer end caps, and the cavity is filled with insulating cotton. Beneficial effects

[0013] This invention provides a double-layer spherical head. Compared with the prior art, it has the following advantages:

[0014] 1. This double-layer spherical end cap, by adopting the design of an inner end cap and an outer end cap, uses a base to fix the inner end cap and the outer end cap together, thereby forming a cavity between the inner end cap and the outer end cap. This effectively isolates the heat exchange between the inside and outside of the end cap, greatly improving its heat insulation effect. Attached Figure Description

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.

[0022] Please see Figure 1-5This utility model provides a technical solution: a double-layer spherical end cap, including a mounting base 1, on which an inner end cap 5 and an outer end cap 2 are fixedly mounted. The inner end cap 5 is fitted inside the outer end cap 2. A first mating ring 6 is integrally mounted on the bottom of the outer end cap 2, and a second mating ring 7 is integrally mounted on the bottom of the inner end cap 5. A first annular groove 12 and a second annular groove 13 are formed on the mounting base 1. The first annular groove 12 and the first mating ring 6 cooperate with each other, and the second annular groove 13 and the second mating ring 7 cooperate with each other. A limiting block 9 is fixedly mounted inside the outer end cap 2. A limiting groove is formed on the limiting block 9. A limiting protrusion 10 is fixedly mounted on the outer surface of the inner end cap 5. The limiting protrusion 10 cooperates with the limiting groove. A cavity is formed between the inner end cap 5 and the outer end cap 2, and the cavity is filled with thermal insulation cotton.

[0023] In use, the inner end cap 5 is first installed onto the mounting base 1 through the mutual cooperation of the second annular groove 13 and the second mating ring 7. Then, the inner end cap 5 is fixed onto the mounting base 1 through welding. Next, metal adhesive is applied to the upper surfaces of the limiting protrusion 10 and the support strip 11. At the same time, thermal insulation cotton is installed on the outer surface of the inner end cap 5. Then, with the mutual cooperation of the limiting grooves opened on the limiting protrusion 10 and the limiting block 9, the outer end cap 2 is installed onto the inner end cap 5. At the same time, with the mutual cooperation of the first annular groove 12 and the first mating ring 6, the outer end cap 2 is also connected to the mounting base 1. Then, the outer end cap 2 is fixedly connected to the mounting base 1 through welding. The design of inner end cap 5, outer end cap 2 and mounting base 1 greatly improves the support strength of the end cap compared with a single-layer circular end cap. At the same time, the cavity formed between the inner end cap 5 and the outer end cap 2 can effectively isolate the heat exchange between the inside and outside of the end cap, while the thermal insulation cotton can effectively play a role in heat insulation.

[0024] Both the inner head 5 and the outer head 2 have through holes 8, and a pressure gauge 4 is installed in the through hole 8. The probe of the pressure gauge 4 extends into the inner head 5; the pressure gauge 4 can monitor the pressure inside the head.

[0025] Several support strips 11 are fixedly installed on the outer surface of the inner end cap 5. The support strips 11 are in close contact with the inner surface of the outer end cap 2. The support strips 11 can be used to enhance the support strength of the inner end cap 5 to the outer end cap 2 and improve stability.

[0026] The bottom of the mounting base 1 is fixedly fitted with a sealing ring 3, which improves the airtightness of the container after the end cap is installed on it.

[0027] Working principle: During the manufacturing process of this double-layer spherical head, the inner head 5 is first installed onto the mounting base 1 through the mutual cooperation of the second annular groove 13 and the second mating ring 7. Then, the inner head 5 is fixed onto the mounting base 1 through welding. Next, metal adhesive is applied to the upper surfaces of the limiting protrusion 10 and the support strip 11, while insulation cotton is installed on the outer surface of the inner head 5. Then, with the mutual cooperation of the limiting grooves opened on the limiting protrusion 10 and the limiting block 9, the outer head 2 is installed onto the inner head 5. At the same time, the first annular groove 12... With the cooperation of the first mating ring 6, the outer end cap 2 is also connected to the mounting base 1. Then, the outer end cap 2 and the mounting base 1 are fixedly connected by welding. Finally, the pressure gauge 4 is installed into the through hole 8. Thus, the double-layer spherical end cap is completed. The design of inner end cap 5, outer end cap 2 and mounting base 1 greatly improves the support strength of the end cap compared with the single-layer circular end cap. At the same time, the cavity formed between the inner end cap 5 and the outer end cap 2 can effectively isolate the heat exchange between the inside and outside of the end cap, while the insulation cotton can effectively play the role of heat insulation.

[0028] Among them, the support strip 11 can be used to enhance the support strength of the inner end cap 5 and the outer end cap 2, and improve the overall stability; after the end cap is installed on the container, the sealing ring 3 fixedly embedded at the bottom of the mounting base 1 can improve the airtightness of the container.
