[0001] The utility model relates to the technical field of pipeline connectors, in particular to a clamp type jacket elbow. Background Technique

[0002] Pipe fittings joints generally refer to the connectors that connect two pipes together, and are mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, and mechanical instruments, as well as mechanical structure components, etc. There are various types of pipe fittings joints, including elbow joints, tee joints, etc.

[0003] For example, the clamp type jacket elbow disclosed in the authorized publication number CN 217762579 U, although it realizes a clamp type jacket elbow, which can achieve the rapid assembly between the elbow body and the jacket, so as to reduce the processing difficulty and improve the production efficiency and quality of the product. However, it does not solve the problem that in the past clamp type jacket elbows, the connection method generally used during use is welding. Such a connection method leads to the need to replace the entire elbow if the elbow is damaged, which may cause waste, and generally only one insulation cavity is provided, resulting in the problem that it is more easily affected by the temperature in the external environment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamp type jacket elbow to solve the problems put forward in the above background technique.

A first connection ring is fixedly arranged on one side of the elbow body. A second connection ring is fixedly arranged at the bottom end of the elbow body. The first connection ring includes an internal sealing groove.

[0008] Preferably, the first connecting fixing plate includes fixing screw holes. The advantage is that the elbow body can be effectively fixed inside the elbow fixing cavity within the first clamp sleeve and the second clamp sleeve through the fixing screw holes, which can effectively ensure the stability of the elbow body when it is inside the elbow fixing cavity.

[0009] Preferably, sealing clamping plates are fixedly arranged at both ends inside the elbow fixing cavity, and external sealing grooves are fixedly arranged inside the sealing clamping plates. The advantage is that when connecting to an external pipeline, the external pipeline can be effectively fixed through the sealing clamping plates and the external sealing grooves, and the sealing performance inside the elbow fixing cavity can be further ensured through the external sealing grooves during fixation.

[0010] Preferably, a heat insulation partition strip is fixedly arranged inside the elbow fixing cavity, and a first heat insulation cavity and a second heat insulation cavity are fixedly arranged on both sides of the heat insulation partition strip. The advantage is that the heat insulation partition strip can effectively divide the inside of the fixing cavity into multiple heat insulation cavities. The heat insulation partition strip can effectively fix the elbow body to ensure the stability of the elbow body when it is inside the elbow fixing cavity.

[0011] Preferably, a first elbow stabilizing strip is fixedly arranged inside the first heat insulation cavity, and a second elbow stabilizing strip is fixedly arranged inside the second heat insulation cavity. The advantage is that through the first elbow stabilizing strip and the second elbow stabilizing strip at both ends, the elbow body can be effectively fixed to ensure the stability of the elbow body when it is inside the elbow fixing cavity.

[0012] Preferably, sealing strips are fixedly arranged inside the internal sealing grooves at the connection parts of the first connecting ring and the second connecting ring with the external pipeline. The advantage is that by inserting the sealing strips into the internal sealing grooves at the connection parts of the first connecting ring and the second connecting ring with the external pipeline, it can effectively ensure that there is no liquid leakage problem during the infusion process, effectively improving the safety and stability of the elbow during use.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. For this kind of clamp - type jacket elbow, during use, first, the first connecting ring and the second connecting ring at both ends of the elbow body are respectively connected to the external pipeline through the internal sealing grooves and the internal sealing strips. After completion of the connection, the first clamp sleeve and the second clamp sleeve are used to fix it. The first clamp sleeve and the second clamp sleeve are combined together, and then the first connecting fixing plate and the second connecting fixing plate are used to fix the first clamp sleeve and the second clamp together. During the fixing process, the external pipeline can be effectively fixed through the sealing clamping plates and the external sealing grooves, and the sealing performance inside the elbow fixing cavity can be further ensured through the external sealing grooves during fixation.

[0015] 2. The beneficial aspect of this clamp - type jacket elbow is that in the previous clamp - type jacket elbows, the generally used connection method during use is welding. Such a connection method results in the need to replace the entire elbow if the elbow part is damaged, which may cause waste problems. And generally only one insulation cavity is provided, which makes it more likely to be affected by the temperature in the external environment. In summary, the previous clamp - type jacket elbows cannot effectively provide a safe and stable working method. Therefore, a clamp - type jacket elbow is proposed. When needed, the first clamp sleeve and the second clamp sleeve can be separated to quickly replace the elbow body inside, which can effectively save some costs. And through the first insulation cavity and the second insulation cavity, the stability inside the insulation cavity can be effectively guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, preferably, the first connection fixing plate 3 includes a fixing screw hole 10. Through the fixing screw hole 10, the elbow body 6 can be effectively fixed inside the elbow fixing cavity 5 inside the first clamp sleeve 1 and the second clamp sleeve 2, which can effectively ensure the stability of the elbow body 6 when it is inside the elbow fixing cavity 5.

[0026] In this embodiment, preferably, sealing clamping plates 11 are fixedly arranged at both ends inside the elbow fixing cavity 5. An external sealing groove 12 is fixedly arranged inside the sealing clamping plates 11. When connecting to an external pipeline, the external pipeline can be effectively fixed through the sealing clamping plates 11 and the external sealing groove 12, and the sealing performance inside the elbow fixing cavity 5 can be further ensured through the external sealing groove 12 during fixation.

[0027] In this embodiment, preferably, a heat insulation partition strip 13 is fixedly arranged inside the elbow fixing cavity 5. A first heat insulation cavity 14 and a second heat insulation cavity 15 are fixedly arranged on both sides of the heat insulation partition strip 13. The heat insulation partition strip 13 can effectively divide the inside of the fixing cavity into multiple heat insulation cavities. The heat insulation partition strip 13 can effectively fix the elbow body 6 to ensure the stability of the elbow body 6 when it is inside the elbow fixing cavity 5.

[0028] In this embodiment, preferably, a first elbow stabilizing strip 16 is fixedly arranged inside the first heat insulation cavity 14, and a second elbow stabilizing strip 17 is fixedly arranged inside the second heat insulation cavity 15. Through the first elbow stabilizing strip 16 and the second elbow stabilizing strip 17 at both ends, the elbow body 6 can be effectively fixed to ensure the stability of the elbow body 6 when it is inside the elbow fixing cavity 5.

[0029] In this embodiment, preferably, a sealing strip 18 is fixedly arranged inside the internal sealing groove 9 at the connection between the first connecting ring 7 and the second connecting ring 8 and the external pipeline.

After the connection is completed, it is fixed by the first clamp sleeve 1 and the second clamp sleeve 2. The first clamp sleeve 1 and the second clamp sleeve 2 are combined together, and then the first clamp sleeve 1 and the second clamp are fixed together through the first connecting fixing plate 3 and the second connecting fixing plate 4. During the fixing process, the external pipeline can be effectively fixed through the sealing card plate 11 and the external sealing groove 12, and the sealing performance inside the elbow fixing cavity 5 can be further ensured through the external sealing groove 12 during fixing. The beneficial point is that in the past clamp-type jacket elbows, the generally used connection method during use was welding. Such a connection method would result in the need to replace the entire elbow if the elbow was damaged, which might cause waste problems. And generally only one heat preservation cavity was provided, which made it more likely to be affected by the temperature in the external environment. To sum up, the past clamp-type jacket elbows could not effectively provide a safe and stable working method. Therefore, a clamp-type jacket elbow is proposed. When needed, the first clamp sleeve 1 and the second clamp sleeve 2 can be separated to quickly replace the internal elbow body 6, which can effectively save a part of the cost, and the stability inside the heat preservation cavity can be effectively ensured through the first heat preservation cavity 14 and the second heat preservation cavity 15.
