Description

Technical Field

[0001] The utility model relates to the technical field of end caps, in particular to a high-strength end cap. Background Art

[0002] A head is a product used to seal pipe fittings. It is welded with round pipe fittings to form a container, which can be used for industrial production, chemical reactions, liquid storage, etc. Thinner and smaller heads can be formed by forging with dies, while larger and thicker heads require rotating plates and pressure forming at the same time to complete the forming of the curved part of the head. However, through the one-time forming of a steel plate, the strength of the head can only be enhanced by thickness, and it is difficult to improve the strength of the head. For heads with low strength requirements, it is difficult to reduce the weight and achieve good thermal insulation performance at the same time. After the head is connected to the pipe fitting, it is often necessary to connect it to an external support mechanism, and the connection method of the welded head is difficult to achieve a detachable connection, which makes it difficult for the head to achieve dual use. If there are fine cracks in the welding between the head and the pipe fitting, there is a risk of leakage, and it is difficult to improve safety. Utility Model Content

[0003] The disclosed embodiment relates to a high-strength head seal, wherein the strengthening layer can consolidate the gap between the inner layer component and the main component body, thereby improving the strength of the head seal.

[0004] In a first aspect of the present disclosure, a high-strength head is provided, specifically comprising: a head body; the head body is composed of a main body and an outer edge plate, the top outer edge of the main body is integrally stamped to form the outer edge plate, and a reinforcement layer is arranged inside the main body; an inner layer member is arranged inside the reinforcement layer, and a connecting ring is fixedly connected to the top surface of the reinforcement layer; a bayonet is provided on the inner top of the connecting ring, and the inner bayonet receives the bayonet ring.

[0005] In at least some embodiments, a notch is machined on the top surface of the inner layer component, a connecting ring is fixed inside the notch, and the joint between the inner layer component and the connecting ring is welded, a connecting pipe is welded on the top of the inner layer component, and the outer joint between the connecting pipe and the head body is welded. The inner layer component is used to withstand the wear resistance, high temperature resistance, corrosion resistance and other requirements of the head, but the thickness of the inner layer component can be reduced, and it can be processed and manufactured through relatively quick methods such as forging, thereby reducing production costs.

[0006] In at least some embodiments, the outer wall of the reinforcement layer is attached to the inner wall of the main body, and the top surface of the reinforcement layer is attached to the bottom surface of the connecting ring. The reinforcement layer can compact the gap between the inner layer and the main body, thereby improving the strength of the head.

[0007] In at least some embodiments, the joint between the closing ring and the connecting ring is welded. When the closing ring is welded to the connecting ring, the inner top edge of the connecting ring can be flushed to ensure a smooth connection between the round tube to be welded and the inner layer component.

[0008] In at least some embodiments, two annular grooves are provided on the top surface of the outer edge plate, connecting holes are provided inside the outer edge plate and outside the annular grooves, threads are provided on the inner walls of the connecting holes, and two sealing strips are clamped on the top of the head body. The sealing strips are complete circular structures and are clamped inside the annular grooves.

[0009] The utility model provides a high-strength head, which has the following beneficial effects:

[0010] In the utility model, the reinforcing layer can compact the gap between the inner layer and the main body, so that the head is strengthened. When a high-strength head is not needed, the reinforcing layer can be selectively not installed, which can reduce the weight of the head and reduce heat transfer. It is more applicable to devices that require heat insulation or cold insulation, and can also reduce the load weight of the supporting round pipe mechanism.

[0011] And when the reinforcement layer is chosen not to be installed, the gap between the main body and the inner layer can be filled to better achieve heat insulation or cold insulation effects, realize multiple usage methods, and improve the applicability of the head to multiple industries.

[0012] In addition, the connecting hole allows the outer edge plate to be directly flange-connected to the circular tube to be sealed, and the sealing strip is clamped inside the annular groove, so that the head body can achieve a detachable sealing connection. When the outer edge plate is welded to the circular tube to be sealed by a fixed welding method, the outer edge plate can provide a connection basis with the external support, thereby realizing a dual-purpose connection of the head.

[0013] In addition, the two welds can be sealed together by a sealing strip. If slight cracks appear on the inner weld during use, they can be sealed by the two sealing strips, thus reducing the probability of leakage during use and improving the safety of the head connection.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example: Please refer to Figures 1 to 6 :

[0031] The utility model proposes a high-strength head, comprising: a head body 1; the head body 1 is composed of a main body 11 and an outer edge plate 12, the top outer edge of the main body 11 is integrally stamped to form the outer edge plate 12, a reinforcement layer 2 is arranged inside the main body 11; an inner layer component 3 is arranged inside the reinforcement layer 2, and a connecting ring 5 is fixedly connected to the top surface of the reinforcement layer 2; a bayonet 501 is opened on the inner top of the connecting ring 5, and a bayonet receiving ring 4 is arranged inside the bayonet 501.

[0032] In the embodiments of the present disclosure, as shown in the attached Figure 3 As shown, the joint between the closing ring 4 and the connecting ring 5 is welded. When the closing ring 4 is welded to the connecting ring 5, the inner top edge of the connecting ring 5 can be flushed, so that the circular tube to be welded and the inner layer component 3 can be smoothly connected. When a height difference needs to be retained between the head and the circular tube to be welded, the closing ring 4 is not welded or assembled, and the head body 1 can be put into use. By turning the bayonet 501 into a bevel with different inclination angles, an inclined connection between the circular tube to be welded and the inner layer component 3 can be achieved, and an internal funnel-shaped smooth connection can be achieved, which is convenient for discharging.

[0033] In the embodiments of the present disclosure, as shown in the attached Figure 6 As shown, the outer wall of the reinforcing layer 2 is attached to the inner wall of the main body 11, and the top surface of the reinforcing layer 2 is attached to the bottom surface of the connecting ring 5. The reinforcing layer 2 can compact the gap between the inner layer 3 and the main body 11 to increase the strength of the head. When a high-strength head is not needed, the reinforcing layer 2 can be selectively not installed, which can reduce the weight of the head and reduce heat transfer. It is more suitable for devices that require heat insulation or cold insulation, and can also reduce the load weight of the supporting circular tube mechanism. When the reinforcing layer 2 is chosen not to be installed, the gap between the main body 11 and the inner layer 3 can be filled to better achieve heat insulation or cold insulation effects.

[0034] In the embodiments of the present disclosure, as shown in the attached Figure 3 As shown, a notch is machined on the top surface of the inner layer component 3, and a connecting ring 5 is fixedly clamped inside the notch, and the seam between the inner layer component 3 and the connecting ring 5 is welded, and a connecting pipe 301 is welded on the top of the inner layer component 3, and the outer seam between the connecting pipe 301 and the head body 1 is welded. The inner layer component 3 is used to withstand the wear resistance, high temperature resistance, corrosion resistance and other requirements of the head, but the thickness of the inner layer component 3 can be reduced, and it can be processed and manufactured by relatively quick methods such as forging, thereby reducing production costs. At the same time, for heads that require low strength, the inner layer component 3 can be used independently without machining a notch, thereby improving production efficiency. The connecting pipe 301 can facilitate the discharge of materials from the tank body, and at the same time, a fastening connection between the main body 11, the reinforcement layer 2 and the inner layer component 3 is added at the bottom to increase the strength of the head.

[0035] In the embodiments of the present disclosure, as shown in the attached Figure 4As shown, two annular grooves 1201 are provided on the top surface of the outer edge plate 12, and connecting holes 1202 are provided inside the outer edge plate 12 and outside the annular grooves 1201. The inner wall of the connecting hole 1202 is provided with a thread, and two sealing strips 1101 are clamped on the top of the head body 1. The sealing strips 1101 are of a complete circular structure and are clamped inside the annular grooves 1201. The outer edge plate 12 can be directly flange-connected to the round pipe to be blocked by using the connecting holes 1202. The sealing strips 1101 are clamped inside the annular grooves 1201, so that the sealing The head body 1 can achieve a detachable sealed connection, and when the outer edge plate 12 is welded to the circular tube to be sealed by a fixed welding method, the outer edge plate 12 can provide a connection basis with the external support. After the sealing strip 1101 is inserted into the annular groove 1201, the inner edge and outer edge of the outer edge plate 12 are respectively welded to the circular tube to be sealed, and the two welds can be sealed by the sealing strip 1101. If slight cracks appear in the inner weld during use, sealing can be achieved by two sealing strips 1101.

[0036] The working principle of this embodiment: Take the case where the reinforcing layer 2, the inner layer component 3 and the closing ring 4 are all connected to the inside of the main body 11 as an example: first place the reinforcing layer 2 inside the main body 11, then place the inner layer component 3 inside the reinforcing layer 2, the connecting ring 5 is clamped to the top of the reinforcing layer 2 and the inner layer component 3, the gaps between the connecting ring 5 and the main body 11 and between the connecting ring 5 and the inner layer component 3 are welded respectively, the closing ring 4 is clamped to the inside of the bayonet 501, the gap between the closing ring 4 and the connecting ring 5 is welded, and the outer seam between the connecting pipe 301 and the head body 1 is welded;
