Description

Technical Field

[0001] This utility model belongs to the field of condensers, specifically relating to an isolation gasket and a condenser. Background Technology

[0002] A condenser is a heat exchange device whose main function is to condense a liquid through heat exchange between media. There are many types of condensers, and the enamel-lined plate condenser is one of them. In an enamel-lined plate condenser, the insulating gasket is a crucial component. The insulating gasket is mainly placed between the enamel-lined plates, and its primary function is to prevent leakage and ensure the normal operation of the condenser.

[0003] Because the gasket prevents liquid leakage, its surface comes into contact with the liquid inside the condenser. Conventional gaskets are typically made of rubber. Therefore, in practice, it has been found that after prolonged use, the gaskets are prone to corrosion, leading to damage and significantly increasing the risk of liquid leakage. Utility Model Content

[0004] This utility model provides an isolation gasket, the purpose of which is to solve the problem that conventional isolation gaskets are prone to corrosion and damage.

[0005] To achieve the above objectives, this utility model provides an isolation gasket, comprising:

[0006] The skeleton, which is ring-shaped; and

[0007] A PTFE layer is disposed on the outer surface of the skeleton, and the PTFE layer protects the skeleton inside.

[0008] This solution places the PTFE layer on the outermost layer. Since the PTFE layer has strong corrosion resistance, it can have a longer service life compared to conventional isolation gaskets in the prior art, and also significantly reduces the risk of liquid leakage caused by corrosion of the isolation gasket.

[0009] Preferably, in order to install the PTFE layer on the outer surface of the skeleton, the PTFE layer in this solution is annular, and the PTFE layer is provided with a receiving cavity, and the skeleton is housed inside the receiving cavity.

[0010] This design constructs a cavity within the PTFE layer, and then houses the skeleton within this cavity, thus enabling the PTFE layer to be mounted on the skeleton surface. When the PTFE layer is mounted on the skeleton surface, it comes into contact with corrosive liquids, providing corrosion resistance.

[0011] Since the PTFE layer needs to be formed in a ring shape, and the connection of the PTFE layer needs to be avoided as much as possible to prevent a decrease in corrosion resistance, the PTFE layer in this solution is ring-shaped, and the PTFE layer is provided with a connection part, and the two ends of the PTFE layer are connected through the connection part.

[0012] This solution connects the PTFE layers end-to-end by incorporating a connecting section, forming a ring-shaped PTFE layer that fits into the ring-shaped skeleton. Furthermore, because only one connecting section is used, the number of connecting sections is reduced, significantly decreasing the likelihood of corrosion at the connecting section leading to PTFE layer damage.

[0013] Preferably, in order to facilitate the installation of the PTFE layer on the skeleton, the outer ring of the PTFE layer in this solution is set with an opening.

[0014] In this design, the outer ring of the PTFE layer is made open, allowing the skeleton to be installed inside the cavity from the outer ring of the PTFE layer during installation. Furthermore, since the outer ring of the skeleton will not come into contact with corrosive liquids, making the outer ring of the PTFE layer open also reduces the amount of PTFE layer used, thus lowering costs.

[0015] Preferably, in order to provide support and prevent the isolation gasket from making hard contact with the outside, the skeleton in this solution includes a support ring and a protective layer, and the protective layer is disposed on the outer surface of the support ring.

[0016] The support ring in this design provides support and increases the strength of the isolation gasket, while the protective layer provides protection to prevent damage from hard contact.

[0017] Preferably, in order to protect the support ring, the protective layer in this solution is configured in a ring shape, and the protective layer is disposed on the surface of the support ring.

[0018] In this design, both the protective layer and the support ring are made into rings. The protective layer is then placed on the surface of the support ring, so the entire support ring can be protected by the protective layer.

[0019] Alternatively, to protect the support ring, the protective layer can be wrapped around the surface of the support ring.

[0020] By wrapping a protective layer around the surface of the support ring, the protective layer is positioned on the surface of the support ring. The protective layer shields the support ring, thus providing protection.

[0021] Preferably, in order to protect both sides of the support ring, this solution sets at least two annular protective layers, with the support ring located between the two protective layers.

[0022] Preferably, in order to fix the protective layer and the support ring, the solution further includes a first fixing layer, which is disposed on the outer surface of the protective layer and encloses the protective layer and the support ring.

[0023] This solution uses a first fixing layer to secure the protective layer and the support ring, preventing them from separating and maintaining their stability.

[0024] Preferably, in order to fix the PTFE layer to the skeleton, the solution further includes a second fixing layer, which is disposed on the outer surface of the PTFE layer and encloses the PTFE layer and the skeleton.

[0025] This solution uses a second fixing layer to wrap the PTFE layer around the skeleton, thus placing the PTFE layer on the skeleton.

[0026] The second aspect of this utility model discloses a condenser, including the aforementioned isolation gasket and condenser plate, wherein multiple condenser plates are provided, and the isolation gasket is disposed between two of the condenser plates.

[0027] The condenser plates in this design are used for heat exchange with the liquid. A gasket is placed between the two condenser plates to provide a seal and prevent liquid leakage.

[0028] Preferably, in order to increase the capacity between the condenser plates, an annular protrusion is provided at the outer surface edge of the condenser plate in this solution, and the isolation gasket contacts the annular protrusion.

[0029] In this design, an annular protrusion is provided at the edge of the outer surface of the condenser plate, and a groove is formed inside the annular protrusion, which can hold liquid.

[0030] The beneficial effects of this utility model are as follows: This solution places the PTFE layer on the outermost layer, and the PTFE layer has strong corrosion resistance. Therefore, compared with conventional isolation gaskets in the prior art, it can have a longer service life and greatly reduce the risk of liquid leakage caused by corrosion of the isolation gasket.

[0041] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0043] Example 1

[0044] The basics are as follows: Figure 1 and Figure 2 As shown, an insulating gasket includes a skeleton 1 and a PTFE layer 2. Both the skeleton 1 and the PTFE layer 2 are made of PTFE material, and the PTFE layer 2 is arranged in a ring shape. The PTFE layer 2 is disposed on the outer surface of the skeleton 1. The PTFE layer 2 has strong corrosion resistance and can protect the skeleton 1 from corrosion damage.

[0045] In this embodiment, the two ends of the PTFE layer 2 are joined by heat fusion, forming a ring shape. Simultaneously, a ring-shaped receiving cavity is provided inside the PTFE layer 2. The outer ring of the PTFE layer 2 is open. Therefore, when the PTFE layer 2 is placed on the frame 1, it shields the inner ring and the top and bottom surfaces of the frame 1, allowing the PTFE layer 2 to directly contact the liquid inside the condenser, preventing corrosion damage. Furthermore, because the outer ring of the PTFE layer 2 is open, it can be fitted onto the frame 1 from the inner ring, facilitating installation.

[0046] After the PTFE layer 2 is placed on the skeleton 1, in order to make the PTFE layer 2 more stable, a second fixing layer 3 is provided on the outside of the PTFE layer 2 in this embodiment. The second fixing layer 3 is a raw material tape, which can be placed on the outer surface of the PTFE layer 2 by wrapping. The second fixing layer 3 wraps the PTFE layer 2 inside, thereby fixing the PTFE layer 2.

[0047] To prevent the PTFE layer 2 from sliding when using the second fixing layer 3 to fix it, this embodiment can provide an adhesive layer on the inner wall of the PTFE layer 2. The adhesive layer can be located at the outer edge of the PTFE layer 2. The adhesive layer can stick the two sides of the opening of the outer ring of the PTFE layer 2 together, thereby constraining the PTFE layer 2 and preventing it from moving or misaligning.

[0048] like Figure 4 As shown, the skeleton 1 in this embodiment includes a support ring 11, a protective layer 12, and a first fixing layer 13. The support ring 11 is preferably made of a metal material, such as iron or carbon steel. A protective layer 12, made of silicone, is provided on the surface of the support ring 11. In this embodiment, the protective layer 12 is preferably annular, and there are two protective layers 12. The two protective layers 12 clamp the support ring 11, thus protecting it. Simultaneously, the width of the protective ring is set greater than the width of the support ring 11, ensuring that the outer side of the support ring 11 is not exposed when the two protective rings clamp it. The first fixing layer 13 is also preferably PTFE tape, which can be applied to the outer surface of the protective layer 12 by wrapping. The first fixing layer 13 serves to fix the support ring 11 and the protective layer 12, keeping them stable and preventing separation.

[0049] It should be noted that: in this embodiment, the support ring 11 is preferably made of metal, but in some other embodiments, the support ring 11 can also be made of other materials in the prior art, such as hard plastic.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that in this embodiment, the PTFE layer 2 is set in a strip shape. The PTFE layer 2 can be applied to the surface of the skeleton 1 by winding. When the PTFE layer 2 is applied to the surface of the skeleton 1 by winding, the PTFE layer 2 can protect the skeleton 1 and prevent it from being corroded.

[0052] Example 3

[0053] The difference between this embodiment and Embodiment 1 is that the protective layer 12 in this embodiment is provided in the form of a strip. The protective layer 12 is a silicone strip. The protective layer 12 is disposed on the surface of the support ring 11 by a winding method. By winding, the protective layer 12 is disposed on the surface of the support ring 11.

[0054] Example 4

[0055] This embodiment is an improvement on embodiment 1, such as... Figure 5 As shown, in Embodiment 1, two protective rings are used, which enclose the support ring 11. Therefore, in Embodiment 1, the edge of the support ring 11 is not shielded; the protective rings need to deform to achieve the effect of shielding the edge of the support ring 11. If the protective rings shift during deformation, the edge of the support ring 11 is easily exposed.

[0056] To address the aforementioned issues, this embodiment preferably provides a protective protrusion on the surface of the protective ring, with the protrusion facing the support ring 11, and the shape of the protective protrusion matching the shape of the support ring 11. The protective protrusion is annular, and when the support ring 11 is sandwiched between two protective rings, the support ring 11 is accommodated inside the protective protrusion. The sidewalls of the protective protrusion effectively shield the side edges of the support ring 11.

[0057] Example 5

[0058] This embodiment provides a condenser, such as Figure 6 As shown, it includes the isolation gasket and condenser plate 4 of Example 1, Example 2, Example 3 or Example 4.

[0059] In this embodiment, multiple condenser plates 4 are arranged in a stacked manner. Each condenser plate 4 includes a top condenser plate 41, a middle condenser plate 42, and a bottom condenser plate 43. The top condenser plate 41 is located at the very top, and the middle condenser plates 42 are located below the top condenser plate 41. Multiple middle condenser plates 42 are arranged vertically. The bottom condenser plate 43 is located below the middle condenser plates 42. Receiving cavities are constructed between the top condenser plate 41 and the middle condenser plate 42, between different middle condenser plates 42, and between the middle condenser plate 42 and the bottom condenser plate 43. These cavities are used to contain liquid.

[0060] like Figure 7 As shown, in this embodiment, to achieve heat exchange, the top condenser 41 is provided with a vertically penetrating injection channel, which allows liquid to enter from the outside into the receiving cavity between the top condenser 41 and the middle condenser 42. Simultaneously, pipe interfaces are provided at both ends of the top condenser 41, communicating with the interior of the top condenser 41. External liquid can enter the interior of the top condenser 41 through the pipe interfaces, and liquid inside the top condenser 41 can also be discharged externally through the pipe interfaces.

[0061] like Figure 8 As shown, in this embodiment, to achieve heat exchange, the middle condenser 42 is provided with a vertically penetrating flow channel, allowing liquid to flow from the top to the bottom of the middle condenser 42. Simultaneously, pipe interfaces are provided at both ends of the middle condenser 42, communicating with the interior of the middle condenser 42. Liquid can enter the interior of the middle condenser 42 through the pipe interfaces, and liquid inside the middle condenser 42 can also be discharged outwards through the pipe interfaces.

[0062] like Figure 9 As shown, in this embodiment, to achieve heat exchange, the bottom condenser 43 is provided with a vertically penetrating discharge channel, allowing liquid to flow from the top to the bottom of the bottom condenser 43. Simultaneously, pipe interfaces are provided at both ends of the bottom condenser 43, communicating with the interior of the bottom condenser 43. External liquid can enter the interior of the bottom condenser 43 through the pipe interfaces, and liquid inside the bottom condenser 43 can also be discharged externally through the pipe interfaces.

[0063] like Figure 6 As shown, in this embodiment, the isolation gaskets are placed between the condenser plates 4, which can seal the edge of the receiving cavity. Specifically, the isolation gaskets are placed between the top condenser plate 41 and the middle condenser plate 42, between two middle condenser plates 42, and between the middle condenser plate 42 and the bottom condenser plate 43.

[0064] In this embodiment, to increase the volume of the receiving cavity, annular protrusions are provided on the opposing surfaces of the four adjacent condenser plates. Specifically, as shown... Figure 7 As shown, the bottom of the top condenser plate 41 has an annular protrusion; as Figure 8 As shown, the top and bottom of the middle condenser plate 42 are also provided with annular protrusions; as Figure 9As shown, an annular protrusion is provided on the top of the bottom condenser 43. The annular protrusion increases the volume of the cavity formed by the top condenser 41 and the middle condenser 42. Similarly, the annular protrusion increases the volume of the cavity formed by the middle condenser 42 and the bottom condenser 43.

[0065] To secure the condenser fins 4, this embodiment includes a fixing structure (not shown in the figure). The fixing structure comprises several connecting units arranged in a ring around the condenser fins 4. Each connecting unit includes a connecting hook and a locking rod. Two connecting hooks are provided, one hooking onto the bottom of the bottom condenser fin 43 and the other onto the top of the top condenser fin 41. The locking rod connects to the two connecting hooks, thereby tightening and securing the vertically arranged condenser fins 4.

[0066] The following detailed description illustrates the specific implementation method: When the condenser is operating, the liquid first enters the receiving cavity between the top condenser plate 41 and the middle condenser plate 42 through the injection channel. When the liquid is in the receiving cavity between the top condenser plate 41 and the middle condenser plate 42, the receiving cavity between the top condenser plate 41 and the middle condenser plate 42 can hold more liquid due to the annular protrusion. Then, the liquid in the receiving cavity between the top condenser plate 41 and the middle condenser plate 42 flows through the guide channel and reaches the receiving cavity between the middle condenser plate 42. After that, the liquid flows sequentially through the receiving cavities between the middle condenser plate 42 located at different heights. Finally, the liquid is released to the outside through the discharge channel on the bottom condenser plate 43.

[0067] Of course, as the liquid passes through different containment chambers, another liquid at a different temperature flows through the pipe interface inside different condenser plates 4, and the liquid completes heat exchange inside the condenser plate 4 and on the outer surface of the condenser plate 4.

[0068] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
