[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate of the ambient air in a building or structure. During installation, it is necessary to lay pipes for return water, etc., and flanges are required when connecting the pipe interface. In order to ensure sealing, a flange gasket is provided for use on air conditioning water pipes.

[0003] Flange gaskets are used in pipe flange connections and are seals between two flanges. The medium, pressure and temperature directly affect the selection of flange gaskets. Air-conditioning water contains trace amounts of fluoride ions, which is because the refrigerant of the air conditioner is mainly Freon. In addition to fluoride ions, air-conditioning water may also contain chloride ions, sulfate ions, nitrate ions and other chemicals, which may corrode the gasket in some cases.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0017] The existing gaskets have a short service life, which affects the sealing effect of the air-conditioning duct and increases the labor cost of subsequent replacement.

[0018] In view of this, a flange gasket is provided for use on air-conditioning water pipes. Through the cooperation between corrosion-resistant sealing rings, corrosion-resistant sealing rings and annular protrusions, the gasket is designed with anti-corrosion on the inside and anti-aging on the outside. This extends the overall service life of the gasket and solves the problem that the existing gaskets have a short service life, which in turn affects the sealing effect of the air-conditioning pipe and increases the labor cost during subsequent replacement.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] Embodiment 1: By Figure 1-3 It can be seen that a flange gasket used for an air conditioning water pipe includes an anti-aging sealing ring 1, the inner side of the anti-aging sealing ring 1 is movably connected to a corrosion-resistant sealing ring 2 by gluing with sealant, the outer side of the corrosion-resistant sealing ring 2 is provided with a plurality of arc-shaped protrusions 3, the outer sides of the plurality of arc-shaped protrusions 3 are glued with the inner side of the anti-aging sealing ring 1 by sealant, and the upper and lower sides of the corrosion-resistant sealing ring 2 are provided with annular protrusions 5;

[0021] In the specific implementation process, it is worth pointing out that the main material of the anti-aging sealing ring 1 is butadiene rubber, which has the characteristics of anti-aging and low temperature resistance. The main material of the corrosion-resistant sealing ring 2 is fluororubber, which not only has good mechanical properties, but also has high resistance to high temperature, oil and corrosion of various chemicals, and has excellent comprehensive performance. The material of the arc-shaped protrusion 3 is the same as that of the corrosion-resistant sealing ring 2. The purpose of the arc-shaped protrusion 3 is to increase the contact area between the corrosion-resistant sealing ring 2 and the anti-aging sealing ring 1, thereby increasing the amount of glue and improving stability. The annular protrusion 5 will be squeezed after the gasket is installed, thereby improving the sealing effect of the interface position;

[0022] Furthermore, a circular hole 4 is formed on the inner side of the corrosion-resistant sealing ring 2, and four positioning holes 6 are formed on the outer side of the anti-aging sealing ring 1;

[0023] In the specific implementation process, it is worth pointing out that the circular hole 4 does not affect the water passing through the pipeline, and the positioning hole 6 does not affect the bolt passing;

[0024] Specifically, when using the flange gasket applied to the air-conditioning water pipe, the gasket is designed to be anti-corrosion on the inside and anti-aging on the outside through the cooperation between the anti-aging sealing ring 1, the corrosion-resistant sealing ring 2 and the annular protrusion 5. This extends the overall service life of the gasket and solves the problem of the short service life of existing gaskets, which in turn affects the sealing effect of the air-conditioning pipe and increases the labor cost during subsequent replacement.

[0025] Embodiment 2: By Figure 1and 4 It can be seen that the top of the anti-aging sealing ring 1 is equipped with a first annular side enclosure 7, and the bottom of the anti-aging sealing ring 1 is equipped with a second annular side enclosure 8. The material of the first annular side enclosure 7 and the second annular side enclosure 8 is the same as that of the anti-aging sealing ring 1.

[0026] In the specific implementation process, it is worth pointing out that the first annular side enclosure 7 and the second annular side enclosure 8 can be tightly attached to the outer side of the flange for sealing, so as to prevent external water from directly entering between the flange and the gasket;

[0027] Specifically, on the basis of the above-mentioned embodiment 1, the flange side is closed through the cooperation between the positioning hole 6, the first annular side enclosure 7 and the second annular side enclosure 8, thereby preventing external water from directly entering the gap between the flange and the gasket, thereby improving the sealing effect and extending the service life of the gasket to a certain extent.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0029] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
