Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing ring technology, and in particular to a pressure warning cap sealing ring. Background Technology
[0002] As is well known, in fluid systems such as pipelines and containers, pressure warning caps are used to monitor internal pressure in real time and achieve sealing. The sealing ring used in the pressure warning cap is a key component, usually made of elastic material, and installed between the cap and the connection port. It fills the gap through elastic deformation, which can not only prevent liquid and gas leakage, but also link with the pressure warning structure inside the cap. For example, through the design of elastic expansion rings, it can assist in triggering the warning signal when the system pressure changes, ensuring the coordinated realization of system sealing and pressure monitoring functions. It is widely used in scenarios that require sealing and pressure warning, such as air conditioning and refrigeration, chemical industry, and pressure vessels.
[0003] Existing sealing rings are prone to liquid or gas leakage during the operation of various mechanical equipment due to gaps between components, thus affecting the normal operation of the mechanical equipment;
[0004] An existing patent (publication number: CN222746604U) discloses a convenient sealing ring, including a sealing ring body. The sealing ring body includes a base ring, a compensation ring, a first connecting pipe, and a second connecting pipe. The compensation ring is embedded in the base ring, and a cavity is provided in the compensation ring. One end of the first connecting pipe and the second connecting pipe are connected to the cavity. The compensation ring is provided on the inner side of the base ring. Initially, if the inner diameter of the base ring is suitable for the material, the cavity in the compensation ring is not filled with filler. If the inner diameter of the base ring is slightly larger than the material, the sealing cap is opened, liquid is introduced through the corresponding connecting pipe, and air is vented through the corresponding connecting pipe. Then, the sealing is performed to ensure that the cavity is filled and the inner wall of the compensation ring is in stable contact with the material, ensuring its stability in use. It can be connected to materials with a certain outer diameter, ensuring its stability in use, without the need to replace the sealing ring of the corresponding specification, making it convenient to use.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, due to the lack of a multi-stage sealing structure, when the sealing ring is subjected to different levels of pressure, it is impossible to progressively increase the sealing performance under different pressure conditions, thus reducing the flexibility of sealing the ring under varying pressure levels.
[0006] To address this, a pressure warning cap sealing ring is proposed. Utility Model Content
[0007] The purpose of this invention is to provide a pressure warning cap sealing ring that can solve the problem of the lack of a multi-stage sealing structure in the existing system, which makes it impossible to adaptively increase the sealing performance in stages under different pressures, thus reducing the flexibility of sealing the ring under different pressure levels.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a pressure warning cap sealing ring, comprising a sealing ring body and a buffer ring, wherein the buffer ring is disposed at the bottom of the sealing ring body;
[0009] The sealing ring body includes a grooved sealing ring, a conical guide ring, a connecting soft ring, and a series of graded rings. The conical guide ring is fixedly connected to the bottom of the grooved sealing ring. The two connecting soft rings are fixedly connected to the inner and outer sides of the bottom of the grooved sealing ring, respectively. The six graded rings are fixedly connected to the inner and outer sides of the conical guide ring, respectively.
[0010] Preferably, the buffer ring includes a buffer component and a pressure component, the buffer component being located at the bottom of the connecting soft ring, and the pressure component being located inside the buffer component.
[0011] Preferably, the cushioning assembly includes an inner airbag ring, an outer airbag ring, and a wave-shaped airbag ring. The inner airbag ring is fixedly connected to the bottom of the connecting soft ring, the outer airbag ring is fixedly connected to the bottom of the inner airbag ring, and the wave-shaped airbag ring is fixedly connected to the top of the outer side of the outer airbag ring. The inner side of the top of the wave-shaped airbag ring is fixedly connected to the outer side of the inner airbag ring.
[0012] Preferably, the pressure assembly includes a top short ring, a middle ring, and a bottom long ring. The two top short rings are fixedly connected to the top of the inner side of the airbag inner ring, the two middle rings are fixedly connected to the inner side of the airbag inner ring, and the two bottom long rings are fixedly connected to the bottom of the inner side of the airbag inner ring.
[0013] Preferably, auxiliary sealing rings are fixedly connected to both the outer and inner sides of the groove sealing ring, and the surface of the auxiliary sealing rings is provided with anti-slip texture.
[0014] Preferably, the inner side of the connecting soft ring is a hollow structure, and a buffer soft ring is fixedly connected to the inner side of the connecting soft ring.
[0015] Preferably, an auxiliary ring is fixedly connected to the inner side of the wave airbag ring, and the side of the auxiliary ring away from the wave airbag ring is fixedly connected to the side of the inner ring of the airbag that is close to the wave airbag ring.
[0016] Preferably, an auxiliary positioning ring is fixedly connected to the inner side of the airbag inner ring, and the inner side of the auxiliary positioning ring is fixedly connected to the surface of the top short ring, the surface of the middle ring and the surface of the bottom long ring respectively.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application, by setting a sealing ring body, allows the grooved sealing ring to cooperate with the conical guide ring, the connecting soft ring, and the graded ring. The grooved sealing ring seals the connection between the pressure warning cap and the equipment, thus sealing the connection between the cap and the equipment. When the grooved sealing ring is pushed by excess pressure, the conical guide ring can move downwards and move the graded ring into the buffer ring, thereby achieving the effect of changing the shape of the buffer ring as the conical guide ring and the graded ring move deeper. The connecting soft ring can connect the grooved sealing ring and the buffer ring, thereby preventing the buffer ring from accidentally falling off the conical guide ring.
[0019] 2. This application incorporates a buffer ring, allowing the buffer assembly to cooperate with the pressure assembly. The inner ring of the airbag connects to the outer ring and the corrugated airbag ring, forming a closed, ring-shaped structure that supports and limits the pressure assembly. The top short ring, middle ring, and bottom long ring change their limiting positions on the sealing ring body as the sealing ring body deepens. Since the bottom long ring is the longest, the middle ring is the second longest, and the top short ring is the shortest, the contact range between the sealing ring body and the top short ring, middle ring, and bottom long ring changes as the sealing ring body deepens. This pushes the buffer assembly away from the sealing ring body, causing it to change its shape under pressure, further pushing the corrugated airbag ring towards the sealing cap, thus increasing the sealing stability at the connection between the pressure warning cap and the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] A pressure warning cap sealing ring includes a sealing ring body 1 and a buffer ring 2, wherein the buffer ring 2 is located at the bottom of the sealing ring body 1;
[0029] The sealing ring body 1 includes a groove sealing ring 11, a conical guide ring 12, a connecting soft ring 13, and a graded ring 14. The conical guide ring 12 is fixedly connected to the bottom of the groove sealing ring 11. The two connecting soft rings 13 are fixedly connected to the inner side and the outer side of the bottom of the groove sealing ring 11, respectively. The six graded rings 14 are fixedly connected to the inner side and the outer side of the conical guide ring 12, respectively.
[0030] In this embodiment: by setting the sealing ring body 1, the groove sealing ring 11 can cooperate with the conical guide ring 12, the connecting soft ring 13 and the graded ring 14. The groove sealing ring 11 seals the connection between the pressure warning cap and the equipment. When the groove sealing ring 11 is pushed by excess pressure, the conical guide ring 12 can move the graded ring 14 downwards into the buffer ring 2. This achieves the effect of changing the shape of the buffer ring 2 as the conical guide ring 12 and the graded ring 14 go deeper. The connecting soft ring 13 can connect the groove sealing ring 11 and the buffer ring 2, thereby preventing the buffer ring 2 from accidentally falling off the conical guide ring 12.
[0031] Specifically, such as Figure 3 As shown, the buffer ring 2 includes a buffer component 21 and a pressure component 22. The buffer component 21 is located at the bottom of the connecting soft ring 13, and the pressure component 22 is located inside the buffer component 21.
[0032] Specifically, such as Figure 4 As shown, the cushioning assembly 21 includes an inner airbag ring 211, an outer airbag ring 212, and a wave-shaped airbag ring 213. The inner airbag ring 211 is fixedly connected to the bottom of the connecting soft ring 13, the outer airbag ring 212 is fixedly connected to the bottom of the inner airbag ring 211, and the wave-shaped airbag ring 213 is fixedly connected to the top of the outer side of the outer airbag ring 212. The inner side of the top of the wave-shaped airbag ring 213 is fixedly connected to the outer side of the inner airbag ring 211.
[0033] Specifically, such as Figure 5 As shown, the pressure assembly 22 includes a top short ring 221, a middle ring 222 and a bottom long ring 223. The two top short rings 221 are fixedly connected to the top of the inner side of the airbag inner ring 211, the two middle rings 222 are fixedly connected to the inner side of the airbag inner ring 211, and the two bottom long rings 223 are fixedly connected to the bottom of the inner side of the airbag inner ring 211.
[0034] In this embodiment: by setting a buffer ring 2, the buffer assembly 21 can cooperate with the pressure assembly 22. The inner ring 211 connects to the outer ring 212 and the wave-shaped airbag ring 213, allowing the buffer assembly 21 to form a ring-shaped closed structure, which can support and limit the pressure assembly 22. The top short ring 221, the middle ring 222, and the bottom long ring 223 can change their limiting positions on the sealing ring body 1 as the sealing ring body 1 is deepened. Since the bottom long ring 223 is the longest, the middle ring... The length of the top short ring 221 is the second longest after the bottom long ring 223, while the top short ring 221 is the shortest. Therefore, as the sealing ring body 1 goes deeper, the contact range between the sealing ring body 1 and the top short ring 221, the middle ring 222 and the bottom long ring 223 will change. This will push the buffer assembly 21 away from the sealing ring body 1, causing the buffer assembly 21 to change its shape due to pressure. This will further push the wave airbag ring 213 towards the cap, thereby further increasing the sealing stability of the pressure warning cap and the connection between the equipment.
[0035] Specifically, such as Figure 2 As shown, auxiliary sealing rings 15 are fixedly connected to both the outer and inner sides of the groove sealing ring 11, and the surface of the auxiliary sealing ring 15 is provided with anti-slip texture.
[0036] Specifically, such as Figure 2 As shown, the inner side of the connecting soft ring 13 is a hollow structure, and a buffer soft ring 16 is fixedly connected to the inner side of the connecting soft ring 13.
[0037] In this embodiment: by setting an auxiliary sealing ring 15 and a buffer soft ring 16, the auxiliary sealing ring 15 can cooperate with the groove sealing ring 11 to further increase the sealing stability of the sealing contact point between the groove sealing ring 11 and the pressure warning cap and the equipment connection. The buffer soft ring 16 can cooperate with the connecting soft ring 13. By setting the connecting soft ring 13 as a hollow structure, it can change the orientation of the groove sealing ring 11 and the inner ring 211 of the airbag, thereby improving the stability of the connecting soft ring 13 when deformed. In addition, the buffer soft ring 16 can provide auxiliary support to the inner side of the connecting soft ring 13, which can further increase the stability of the connecting soft ring 13 when reset.
[0038] Specifically, such as Figure 4As shown, an auxiliary ring 214 is fixedly connected to the inner side of the wave airbag ring 213. The side of the auxiliary ring 214 away from the wave airbag ring 213 is fixedly connected to the side of the inner airbag ring 211 close to the wave airbag ring 213.
[0039] Specifically, such as Figure 5 As shown, an auxiliary positioning ring 224 is fixedly connected to the inner side of the inner ring 211 of the airbag. The inner side of the auxiliary positioning ring 224 is fixedly connected to the surface of the top short ring 221, the surface of the middle ring 222, and the surface of the bottom long ring 223, respectively.
[0040] In this embodiment: by setting an auxiliary ring plate 214 and an auxiliary positioning ring 224, the auxiliary ring plate 214 can cooperate with the wave airbag ring 213 to provide auxiliary support for the inner side of the wave airbag ring 213. When the wave airbag ring 213 needs to be reset, it can be auxiliaryly limited, further increasing the stability of the wave airbag ring 213 after reset. The auxiliary positioning ring 224 can cooperate with the top short ring 221, the middle ring 222 and the bottom long ring 223 to provide auxiliary limitation at the connection between the top short ring 221 and the inner ring 211 of the airbag, the connection between the middle ring 222 and the inner ring 211 of the airbag, and the connection between the bottom long ring 223 and the inner ring 211 of the airbag, respectively. This can further increase the stability of the inner ring 211 of the airbag when connected with the top short ring 221, the middle ring 222 and the bottom long ring 223.
[0041] Working principle: First, the grooved sealing ring 11 and the buffer assembly 21 are installed between the pressure warning cap and the required connected equipment. When the pressure inside the pressure warning cap increases, the grooved sealing ring 11 moves outward along the space between the pressure warning cap and the equipment as the pressure increases. Simultaneously, it moves the conical guide ring 12. At this time, the conical guide ring 12 drives the grading ring 14 to move towards the inner side of the airbag inner ring 211. The grading ring 14 gradually contacts the top short ring 221, the middle ring 222, and the bottom long ring 223, and... When the graded ring 14 contacts the top short ring 221, the middle ring 222, and the bottom long ring 223 in sequence, the top short ring 221, the middle ring 222, and the bottom long ring 223 will push the inner ring 211 of the airbag away from the graded ring 14 in sequence. The inner ring 211 of the airbag will be deformed by the compression generated by the push. At the same time, the outer ring 212 of the airbag and the wave airbag ring 213 will further contact the pressure warning cap as they deform, until the inner ring 211 of the airbag, the outer ring 212 of the airbag, and the wave airbag ring 213 can no longer deform with the movement of the graded ring 14.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
