Description

Technical Field

[0001] The utility model discloses a new type of Rock ring connection structure, belonging to the technical field of refrigeration pipeline connection, relating to a new type of Rock ring connection structure for cold connection of refrigeration pipelines, and specifically relating to a new type of Rock ring connection structure for cold connection of refrigeration pipelines. Background Technique

[0002] The traditional connection methods of refrigeration pipelines mainly use resistance welding and flame welding, which have high requirements for personnel operation. During this process, open fire and solder are required, and at the same time, high heat, toxic and harmful gases will be generated, and there may also be adverse effects such as high leakage.

[0003] Currently, the cold connection structures commonly used in the market are mainly pipe joint ring connections. However, due to the influence of pipelines and operations in the connection structure, there will be a certain probability of leakage. Once leakage occurs in refrigeration pipelines in the market, the maintenance and after-sales costs will be very high. Content of the Utility Model

[0004] Purpose of the utility model: To provide a new type of Rock ring connection structure for cold connection of refrigeration pipelines, and solve the problem of leakage caused by the influence of pipelines and operations in the current cold connection technology of refrigeration management as mentioned in the above background technique.

[0005] Technical solution: A new type of Rock ring connection structure for cold connection of refrigeration pipelines, including a connection and installation component. The connection and installation component includes a new type of Rock ring, an outer sleeve, an inner insertion tube, a sealing liquid, and a sealing glue. The inner ring part of the new type of Rock ring sequentially includes a guiding section, an anti-torsion section, a liquid storage section, a locking section, and an identification end. Among them, the radius of the guiding section gradually decreases from the inner ring end towards the inside. Both the anti-torsion section and the locking section are stepped tightening structures, and the radius of the anti-torsion section is greater than the radius of the locking section. The liquid storage section is used to store the sealing glue. The outer sleeve is sleeved on the port of the inner insertion tube and is located between the new type of Rock ring and the inner insertion tube. The new type of Rock ring is installed on the outside of the outer sleeve. A connection limit part is arranged at a certain distance from the pipe orifice end of the outer sleeve.

Its characteristic is that in an anaerobic environment, after contacting with metal, it initially cures within 2 - 5 minutes and has a certain strength. The cured layer of the sealing liquid is located between the overlapping surfaces of the outer sleeve and the inner insertion tube. If these two are different metals, this can maximize the prevention of galvanic corrosion and improve the overall anti-corrosion and sealing performance. The sealing glue is a highly permeable and fast-curing sealing glue, and its characteristic is that it cures within 2 minutes in an aerobic environment and has high strength. The sealing glue is coated inside the liquid storage section of the new type of Rock ring, on the pipe orifice of the outer sleeve, and on the outside of the inner insertion tube.

[0015] Preferably, the sealing liquid is a high-permeability anaerobic adhesive filler, which can fill the fine grooves between the outer tube and the inner tube to improve the sealing performance. Its characteristics are that it will initially solidify in 2 to 5 minutes after contacting with metal in an anaerobic environment and has a certain strength.

[0016] Preferably, the sealing glue is a high-permeability fast-setting sealing glue, which has the characteristics of being cured within 2 minutes in an aerobic environment and having high strength.

[0017] Preferably, the sealing glue is coated on the inside of the liquid storage section of the novel lock ring, the opening of the outer tube and the outside of the inner tube.

[0034] In this embodiment, the radius of the anti-torsion section 12 is greater than that of the locking section 11.

[0035] In this embodiment, the liquid storage section 13 is used to store the sealing glue 5.

[0036] In this embodiment, the identification end 15 is arranged on the outer surface of the new Roke ring 1 near the guiding section 14.

[0037] In this embodiment, the identification end 15 facilitates the direction identification during the installation of the new Roke ring.

[0038] In this embodiment, one end of the outer sleeve 2 penetrates through the inner locking section 11 of the new Roke ring 1 and extends at least 1 mm.

[0039] In this embodiment, the outer sleeve 2, the inner insert tube 3 and the new Rock ring 1 are connected to form a crimping and compressing section, that is, a sealed overlapping portion composed of the outer sleeve connection section 21, the inner insert tube connection section 31 and the solidified layer of the sealing liquid 4.

[0040] In this embodiment, inside the liquid storage section 13 of the new Rock ring 1 after the crimping of the new Rock ring 1, the outer sleeve 2 and the inner insert tube 3, there is a solidified layer of the sealing glue 5 at the nozzle of the outer sleeve 2 and outside the inner insert tube 3.

[0048] When the outer sleeve 2 and the inner insert tube 3 of the refrigeration device are connected, the inner insert tube 3 is connected to the outer sleeve 2 through the new Rock ring 1, and the steps are as follows;

[0050] Second, the sealing liquid 4 is dropped at the nozzle of the outer sleeve 2. Under the capillary effect and the high permeability of the sealing liquid 4, the space between the outer sleeve connection section 21 and the inner insert tube connection section 31 is filled with the sealing liquid 4, so that the sealing between the inner insert tube 3 and the outer sleeve 2 is stable.

[0051] Third, apply a certain force to slide and crimp the new Rock ring 1 towards the outer sleeve connection section 21. The sealing liquid is compressed, and an annular solidified layer of the sealing liquid 4 is formed between the outer sleeve connection section 21 and the inner insert tube connection section 31.

[0052] At this time, after the new Rock ring 1 tightly sleeves the inner insertion tube 3 and the outer sleeve tube 2, a circumferential overlapping compression seal is formed. The operation is simple. The sealing liquid 4 can fill the fine grooves on the outer sleeve tube 2 and the inner insertion tube 3 and form a solidified sealing layer between the tubes, improving the sealing performance;

[0053] Fourth, apply the sealing glue 5 inside the liquid storage section 13 of the new Rock ring 1, at the pipe orifices of the outer sleeve tube 2 and on the outer surface of the inner insertion tube 3, so as to add a sealing layer outside the connection point of the cold connection, eliminate the interference of external factors such as pipelines and personnel operations on the connection quality, and ensure zero leakage.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this utility model creation.
