Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a flared-mouth ferrule connector. Background Technology

[0002] Firefighting equipment pipelines need to meet requirements such as corrosion resistance and robustness, and copper pipe fittings are often used. When connecting firefighting equipment pipelines with shipyard pipelines, fittings are required to connect the two.

[0003] Currently, when connecting small- to medium-diameter fire-fighting equipment pipelines to shipyard pipelines, flared joints generally provide reliable sealing and pressure-bearing capacity for fire-fighting systems with moderate pressure.

[0004] However, if the shipyard pipeline is flared using a flared connector, a pipeline test is required after the fire equipment pipeline is connected to the shipyard pipeline. If a problem occurs, the connection needs to be disassembled. The flared connector needs to be flared again every time it is disassembled and reassembled, which causes significant damage to the shipyard pipeline and is inconvenient to use. Summary of the Invention

[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] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A flared-end to ferrule type connector includes a transfer component 1, one end of the transfer component 1 is threadedly connected to a ferrule end component 2, and the other end of the transfer component 1 is threadedly connected to a flared end component 3, and an auxiliary limiting component 4 is provided between the flared end component 3 and the ferrule end component 2.

[0029] The transfer component 1 includes a transfer connecting pipe 101, and the end of the transfer connecting pipe 101 near the flared end component 3 has a tapered structure;

[0030] The ferrule end assembly 2 includes a ferrule nut body 203 that is threaded to one end of the transfer connecting pipe 101. The ferrule nut body 203 has a ferrule connector body 201 inside, and a ferrule body 202 is provided on one side of the ferrule connector body 201.

[0031] The flared end assembly 3 includes a flared nut 302 threadedly connected to the other end of the transfer connecting pipe 101. The flared nut 302 has a flared connector body 301 inside. Two sets of fixing nuts 102 are fixed to the outside of the transfer connecting pipe 101. The ferrule end assembly 2 also includes a ferrule nut connecting ring 204 disposed at one end of the ferrule nut body 203. The inner diameter of the ferrule nut body 203 near the transfer connecting pipe 101 is larger than the inner diameter of the other end. The flared end assembly 3 also includes a flared nut connecting ring 303 fixed to one end of the flared nut 302. The inner diameter of the flared nut 302 near the transfer connecting pipe 101 is larger than the inner diameter of the other end. The flared connector body 301 has a T-shaped structure, and the ferrule connector body 201 has a conical structure.

[0032] By adopting the above technical solution, the shipyard pipeline interface is a common interface, while the fire-fighting interface is a copper pipe interface. The ferrule end assembly 2 is used to connect the shipyard pipeline interface, while the flared end assembly 3 is used to connect the fire-fighting interface. During connection, the ferrule connector body 201 and ferrule body 202 are fitted over the shipyard pipeline interface. Then, the ferrule connector body 201 and ferrule body 202 are inserted into the transfer connecting pipe 101. The ferrule nut body 203 is rotated to thread it onto the transfer connecting pipe 101. By using a tool to rotate the ferrule nut body 203 and the fixing nut 102, the shipyard pipeline interface and the transfer connecting pipe 101 are connected. On the other hand, the flared end assembly 301... The fire-fighting interface copper pipe is fitted onto the fire-fighting interface copper pipe. Then, using a tool, the fire-fighting interface copper pipe is shaped into a flared structure. The flared connector body 301 is inserted into the transfer connecting pipe 101. The flared connector body 301 is embedded in the flared nut 302, and the flared nut 302 is threadedly connected to the transfer connecting pipe 101. By rotating the flared nut 302 and the fixing nut 102 with a tool, the fire-fighting interface copper pipe and the transfer connecting pipe 101 are connected to each other. Through the set clamp end assembly 2 and flared end assembly 3, the shipyard pipeline interface and the copper pipe interface can be directly connected to each other, improving the connection efficiency. At the same time, the shipyard pipeline interface and the clamp end assembly 2 are easy to disassemble and reassemble, without affecting the repeated disassembly and assembly of the shipyard pipeline interface.

[0033] Specifically, such as Figure 4 As shown, the auxiliary limiting component 4 includes a collar 401 rotatably mounted on the flared nut connecting ring 303 and the ferrule nut connecting ring 204, respectively. An embedded groove 405 is provided at the connection between the collar 401 and the ferrule nut connecting ring 204 and the flared nut connecting ring 303, and an embedded block 406 is movably disposed inside the embedded groove 405. The auxiliary limiting component 4 also includes a limiting ear plate 402 fixed around the collar 401. A limiting screw 403 passes through the inside of the limiting ear plate 402, and a limiting nut 404 is threadedly connected to the surface of the limiting screw 403.

[0034] By adopting the above technical solution, after connecting the fire-fighting interface and the shipyard pipeline interface together through the ferrule nut body 203 and the flared nut 302, rotating the collar 401 causes the embedded locking block 406 on the collar 401 to rotate within the embedded locking groove 405, adjusting the position of the limiting ear plate 402 on the collar 401. This ensures that the positions of the limiting ear plates 402 around the collar 401 on the two sets of flared nut connecting rings 303 and ferrule nut connecting ring 204 are matched. The limiting screw 403 can be inserted into the limiting ear plate 402. By rotating the limiting nut 404, the limiting screw 403 is locked, limiting the ferrule nut body 203 and the flared nut 302. Through the auxiliary limiting component 4, the limiting ear plate 402 can be limited by the limiting screw 403, increasing the connection stability between the ferrule nut body 203 and the flared nut 302 and the fire-fighting interface and the shipyard pipeline interface.

[0035] Working principle: The ferrule end assembly 2 is used to connect to the shipyard pipeline interface, while the flared end assembly 3 is used to connect to the fire-fighting interface. During connection, the ferrule connector body 201 and ferrule body 202 are fitted onto the outside of the shipyard pipeline interface. Then, the ferrule connector body 201 and ferrule body 202 are inserted into the transfer connecting pipe 101. The ferrule nut body 203 is rotated to thread it onto the transfer connecting pipe 101. By rotating the ferrule nut body 203 and the fixing nut 102 with a tool, the shipyard pipeline interface and the transfer connecting pipe 101 are connected. On the other hand, the flared connector body 301 is fitted onto the fire-fighting interface copper pipe. Then, using a tool, the fire-fighting interface copper pipe is shaped into a flared structure, and the flared connector body 301 is inserted into the transfer connecting pipe 101. The body 301 is embedded in the flared nut 302, which is threadedly connected to the transfer connecting pipe 101. By rotating the flared nut 302 and the fixing nut 102 with a tool, the fire interface copper pipe and the transfer connecting pipe 101 are connected to each other. Then, the collar 401 is rotated, and the embedded locking block 406 on the collar 401 rotates in the embedded locking groove 405, adjusting the position of the limiting ear plate 402 on the collar 401 so that the positions of the limiting ear plates 402 around the collar 401 on the two sets of flared nut connecting rings 303 and the ferrule nut connecting ring 204 are matched. The limiting screw 403 can be inserted into the limiting ear plate 402. By rotating the limiting nut 404, the limiting screw 403 is locked, thus limiting the ferrule nut body 203 and the flared nut 302.
