Description

Technical Field

[0001] This utility model relates to a type of end cap, specifically a lock-edge end cap, and belongs to the technical field of end caps. Background Technology

[0002] Locking end caps are a type of end cap used in pressure vessels. They are characterized by a locking structure at the edge of the end cap to improve its sealing performance and strength. They are usually hemispherical. Locking end caps are widely used in general pressure vessels in industries such as oil refining, chemical, transportation, food, environmental protection, home appliances, and general applications. They are especially used in various pipeline systems for sealing the ends of pipelines to prevent gas leakage and ensure the safe operation of the pipeline system.

[0003] Existing end caps typically use sealing sleeves at the contact points with external equipment to enhance sealing, and various external latches for securing them. However, this method is inconvenient for inspection. To prevent leaks, the sealing performance and structural integrity of the end caps must be checked regularly during use to promptly identify and address any issues. Current methods require specialized personnel to inspect the sealing performance, which involves visual inspection and touch, making the process cumbersome. Therefore, we offer a lock-edge type end cap to solve these problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a locking end cap, and the specific technical solution is as follows:

[0005] A locking end cap includes an end cap body and a pipe located on one side of the end cap body. The end cap body has a sealing mechanism inside to increase the sealing effect between the end cap body and the pipe. A fixing ring is fitted around the end cap body and the pipe, forming an annular cavity between the fixing ring and the pipe. A fixing cylinder is fixedly connected to the inner wall of the fixing ring. A piston is slidably connected to the inner wall of the fixing cylinder. A sliding rod is connected to one side of the piston. A reflective sticker is adhered to one end of the sliding rod. The outer surface of the reflective sticker is slidably connected to the fixing cylinder. A vent is provided at one end of the fixing cylinder.

[0006] Preferably, the sealing mechanism includes an inner ring, which is located inside the head body and integrally formed with the head body, and an annular groove is formed between the inner ring and the head body.

[0007] Preferably, a first sealing ring is installed on the inner side of the inner ring, and a second sealing ring is installed on the inner wall of the end cap body. The outer surfaces of both the first and second sealing rings are connected to the pipeline.

[0008] Preferably, each of the fixed rings has two third sealing rings connected to its outer surface, and the outer surfaces of the two third sealing rings are respectively connected to the head body and the pipe.

[0009] Preferably, the upper and lower parts of the fixing ring are both connected to fixing members, and two adjacent fixing members are detachably connected.

[0010] Preferably, an installation ring is fixedly connected to the outer surface of the pipe, and one side of the installation ring is detachably connected to the end cap body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This locking-edge type end cap, through the setting of components such as a fixing ring and a piston, allows gas inside the pipeline to leak through the sealing mechanism, first entering the interior of the annular chamber. This causes the pressure inside the piston to be greater than that outside, driving the sliding rod to slide outward and exposing the reflective sticker, thus alerting inspectors. Simply shine a flashlight on the end of the fixing ring and observe whether the reflective sticker is exposed to determine the pressure inside the annular chamber, thereby identifying whether a leak has occurred. Then, the leaking part can be repaired. This achieves a convenient inspection effect, solving the problem of existing systems requiring specialized personnel to inspect the seals, which is cumbersome and can only be done by observation and touch.

[0013] 2. This locking end cap, through the setting of sealing mechanism and other components, fits the end cap body onto the end of the pipe, allowing the pipe to enter between the inner ring and the end cap body to increase the contact area and thus enhance the sealing effect. The first and second sealing rings are both pressed against the end of the pipe to increase the resistance to gas movement to the outside, thereby further enhancing the sealing effect. By fixing the end cap body and the mounting ring together, the pipe and the end cap body are fixed so as to seal the end of the pipe, thereby achieving the effect of enhancing the sealing.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] Please see Figures 1-5 The device includes a head body 1 and a pipe 2 located on one side of the head body 1. A sealing mechanism 3 is provided inside the head body 1 to enhance the sealing effect between the head body 1 and the pipe 2. A fixing ring 4 is fitted around the head body 1 and the pipe 2, forming an annular chamber 5 between the fixing ring 4 and the pipe 2. A fixing cylinder 6 is fixedly connected to the inner wall of the fixing ring 4, and a piston 7 is slidably connected to the inner wall of the fixing cylinder 6. A sliding rod 8 is connected to one side of the piston 7, and a reflective sticker 9 is adhered to one end of the sliding rod 8. The outer surface of the reflective sticker 9 is slidably connected to the fixing cylinder 6. A vent 10 is provided at one end of the fixing cylinder 6. The head body 1 is installed on the pipe 2. The end is sealed, and the sealing mechanism 3 can increase its sealing effect. There are two fixing rings 4, each of which is semi-circular in shape. The two fixing rings 4 form a ring that covers the head body 1 and the pipe 2. When the gas inside the pipe 2 leaks through the sealing mechanism 3, it will first enter the interior of the annular chamber 5, which will increase the gas pressure inside the annular chamber 5. This will cause the pressure inside the piston 7 to be greater than that outside, thus causing the piston 7 to slide outward, thereby driving the sliding rod 8 to slide outward, exposing the position of the reflective sticker 9 so as to warn the inspectors and quickly determine the sealing condition of the head.

[0022] The sealing mechanism 3 includes an inner ring 301, which is located inside the head body 1 and integrally formed with the head body 1. An annular groove is formed between the inner ring 301 and the head body 1. During installation, the end of the pipe 2 is inserted into the annular groove to increase the contact area and thus increase the sealing effect.

[0023] A first sealing ring 302 is installed on the inner side of the inner ring 301, and a second sealing ring 303 is installed on the inner wall of the end cap body 1. The outer surfaces of the first sealing ring 302 and the second sealing ring 303 are both connected to the pipe 2. During installation, the first sealing ring 302 and the second sealing ring 303 are pressed against each other at the end of the pipe 2. The first sealing ring 302 is in contact with the inner wall of the pipe 2, and the second sealing ring 303 is in contact with the end of the pipe 2. Both are located at the necessary passage for gas leakage, so as to increase the resistance of gas to move to the outside, thereby further increasing the sealing effect.

[0024] Two third sealing rings 11 are connected to the outer surface of each fixed ring 4. The outer surfaces of the two third sealing rings 11 are connected to the head body 1 and the pipe 2 respectively. The two third sealing rings 11 can increase the sealing between the fixed ring 4 and the pipe 2, thereby sealing the connection between the head body 1 and the pipe 2. This allows the leaked gas to enter the annular chamber 5 first, so that components such as the piston 7 can detect the gas pressure.

[0025] The upper and lower parts of the fixing ring 4 are both connected to fixing members 12. The two adjacent fixing members 12 are detachably connected. The two adjacent fixing members 12 can be fixed by bolts. By fixing the upper and lower fixing members 12, the two fixing rings 4 can be fixed together to form a ring.

[0026] An installation ring 13 is fixedly connected to the outer surface of the pipe 2. One side of the installation ring 13 is detachably connected to the end cap body 1. The installation ring 13 and the end cap body 1 can be fixed together by bolts to prevent gaps from forming between the end cap body 1 and the installation ring 13. Depending on the actual needs, the end cap body 1 can also be directly welded together without having to be removed.

[0027] The first sealing ring 302, the second sealing ring 303, and the third sealing ring 11 in this application are all made of rubber material and have a certain deformation capacity. When squeezed, they can fill the gap between the two sides to increase the sealing performance. They are all common sealing structures in the present invention.

[0028] During installation, the following steps are taken: First, the end cap body 1 is fitted onto the end of the pipe 2, allowing the pipe 2 to enter between the inner ring 301 and the end cap body 1. By fixing the end cap body 1 and the mounting ring 13 together, the pipe 2 and the end cap body 1 are fixed, thus sealing the end of the pipe 2. A first seal is formed by the sealing mechanism 3. Then, two fixing rings 4 are fitted onto the interface and closed together, and fixed by the fixing member 12, thereby adding a second seal to the connection and achieving the effect of increasing the seal.

[0029] When gas leaks through the sealing mechanism 3 inside pipe 2, it first enters the annular chamber 5, increasing the gas pressure inside the annular chamber 5. This causes the pressure inside piston 7 to be greater than that outside, causing piston 7 to slide outward. This, in turn, causes sliding rod 8 to slide outward, exposing the reflective sticker 9 to alert inspectors. During routine inspections, the sealing condition of this end cap does not require close observation. Simply shine a flashlight on the end of the fixing ring 4 and observe whether the reflective sticker 9 leaks out to determine the pressure inside the annular chamber 5, thus identifying whether there is a leak. Then, select the leaking area for repair, achieving a convenient inspection effect.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
