[0002] like Figure 1 As shown, the existing union ball valve includes a valve body 100', a union 200', and a double-threaded connector 300'. Both the valve body 100' and the union 200' are provided with internal thread interfaces. The valve body 100' and the union 200' cannot be directly connected. They need to be connected through the double-threaded connector 300' with external threaded connectors at both ends. This will affect the installation and disassembly efficiency of the union ball valve, and the replacement of the ball valve is more troublesome and inconvenient for maintenance.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] Example 1

[0027] like Figures 2-5 As shown, this utility model embodiment provides a swivel ball valve, including a valve body 100, at least one end of the valve body 100 is a swivel end, and the swivel end of the valve body 100 is provided with a swivel joint 200.

[0028] It is understood that the ball valve in this embodiment can be a single-joint ball valve, that is, one end of the valve body 100 is a joint end for connecting one joint 200, or it can be a double-joint ball valve, that is, both ends of the valve body 100 are joint ends for connecting two joints 200.

[0029] The valve body 100 has a first external threaded connector 110 at the union end, and the union 200 has a first internal threaded interface 211 that is adapted to the first external threaded connector 110. The first external threaded connector 110 on the valve body 100 is threadedly connected to the first internal threaded interface 211 on the union 200.

[0030] Optionally, refer to Figure 2 and Figure 3 The valve body 100 is provided with a first external turning part 120 near the first external threaded joint 110. This makes it easy to use the external wrench and the first external turning part 120 to turn the valve body 100 during the installation and disassembly of the valve body 100.

[0031] Optionally, refer to Figure 4 and Figure 5The valve body 100 has an internal turning part 130 inside the first external threaded joint 110. This allows the valve body 100 to be turned by combining an internal wrench with the internal turning part 130 during installation and disassembly. At the same time, the turning part is located inside the first external threaded joint 110, and there is no need to set a turning part outside the first external threaded joint 110, which helps to shorten the length of the union ball valve.

[0032] In some embodiments, refer to Figure 3 and Figure 5 The union 200 includes a valve body connector 210, a pipe connector 220, and a locking nut 230. A first internal thread interface 211 is located inside one end of the valve body connector 210, and an external protruding ring 212 is located outside the other end of the valve body connector 210. A second internal thread interface 221 is located inside one end of the pipe connector 220, and a second external thread interface 222 is located outside the other end of the pipe connector 220. The end of the external protruding ring 212 of the valve body connector 210 is connected to the end of the second external thread interface 222 of the pipe connector 220. An internal protruding ring 231 is located inside one end of the locking nut 230, and a third internal thread interface 232 is located inside the other end of the locking nut 230. The internal protruding ring 231 is sleeved on the outside of the valve body connector 210 and abuts against the side of the external protruding ring 212 away from the pipe connector 220. The third internal thread interface 232 is threadedly connected to the outside of the second external thread interface 222.

[0033] When installing the union 200, first put the locking nut 230 on the outside of the first external threaded joint 110 on the valve body 100, then tighten the first internal threaded interface 211 of the valve body joint 210 onto the first external threaded joint 110 of the valve body 100, and at the same time tighten the second internal threaded interface 221 of the pipe joint 220 onto the pipe, and finally tighten the third internal threaded interface 232 of the locking nut 230 onto the second external threaded joint 222 of the pipe joint 220.

[0034] Optionally, to improve sealing, a sealing ring is provided between the mating ends of the valve body connector 210 and the pipe connector 220, and water-based adhesive tape is wrapped between each external threaded connector and the internal threaded interface.

[0035] To facilitate the tightening of the valve body connector 210, pipe connector 220 and locking nut 230 using a wrench, the valve body connector 210 is provided with a second external tightening part 213, the pipe connector 220 is provided with a third external tightening part 223, and the locking nut 230 is provided with a fourth external tightening part 233.

[0036] This application provides an external threaded connector 110 at the union end of the valve body 100, allowing the valve body 100 to be directly connected to the internal threaded interface of the union 200 via the external threaded connector 110. This eliminates the need for a double-threaded connector in the middle, simplifies the structure of the union ball valve, improves installation efficiency, facilitates ball valve replacement, and saves maintenance time.

[0037] Example 2

[0038] like Figures 6-7 As shown, this utility model embodiment provides a union ball valve. The difference between embodiment 2 and embodiment 1 lies in the structure of the union 200.

[0039] In this embodiment, the union 200 includes a pipe joint 220 and a locking nut 230. One end of the pipe joint 220 has a second internal thread interface 221 inside, and the other end of the pipe joint 220 has an external protruding ring 212 outside. The external protruding ring 212 of the pipe joint 220 abuts against the union end of the valve body 100. The first internal thread interface 211 is located inside one end of the locking nut 230, and the other end of the locking nut 230 has an internal protruding ring 231 inside. The internal protruding ring 231 of the locking nut 230 is sleeved on the outside of the pipe joint 220 and abuts against the side of the external protruding ring 212 away from the valve body 100. The first internal thread interface 211 of the locking nut 230 is threadedly connected to the outside of the first external thread joint 110 of the valve body 100.

[0040] When installing the union 200, first put the lock nut 230 on the pipe, then tighten the second internal thread interface 221 of the pipe joint 220 onto the pipe, and finally tighten the first internal thread interface 211 of the lock nut 230 onto the first external thread interface 110 of the valve body 100.

[0041] Compared to the union structure in Embodiment 1, this embodiment requires increasing the outer diameter of the first external threaded joint 110, which eliminates the need for the valve body joint 210, further simplifying the structure and improving installation efficiency.

[0042] Optionally, to improve sealing, a sealing ring is provided between the mating ends of the valve body 100 and the pipe joint 220, and water-based adhesive tape is wrapped between each external threaded joint and the internal threaded interface.

[0043] Similarly, in order to facilitate the tightening of the pipe joint 220 and the locking nut 230 by means of a wrench, the pipe joint 220 is provided with a third external tightening part 223, and the locking nut 230 is provided with a fourth external tightening part 233.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
