[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-5 , a technical solution provided by the utility model:

[0021] In this embodiment, a rotary joint for preventing fluid leakage includes a joint 1, an inner tube 2 is fixedly provided inside one side of the joint 1, a rubber strip 3 is fixedly provided on the outer surface of the inner tube 2, and a through groove 4 is opened at one end of the inner tube 2 located in the joint 1, a rubber strip 2 7 is provided in the through groove 4, a joint 2 8 is rotatably provided on the outer surface of the inner tube 2 at one end of the joint 1, a flange 11 is fixedly provided on the outer surface of the joint 2 8, a slide rail 13 is fixedly provided on the outer surface of the joint 2 8, and a flange 2 14 is slidably provided on the outer surface of the slide rail 13.

[0022] In this embodiment, the length of the inner tube 2 is half of the connector 1, one end of the inner tube 2 inside the connector 1 is located in the middle of the connector 1, and a retaining bar 5 is fixedly provided on one side of the through groove 4 close to the center of the circle.

[0023] In this embodiment, the two ends of the baffle 5 are fixedly connected to the inner tube 2 and the joint 1 respectively, the rubber strip 2 7 is located on the outside of the baffle 5, and a limiting plate 6 is provided on the outside of the rubber strip 2 7, and the cross section of the limiting plate 6 is set to be arc-shaped.

[0024] In this embodiment, there are four limit plates 6, with gaps between each limit plate 6. A slot 9 is provided inside the joint 2 8, and the number of the slots 9 is the same as the number of the rubber strip 1 (3) and the size is consistent.

[0025] In this embodiment, one end of joint 2 8 is located inside joint 1, and joint 2 8 is rotatably connected to joint 1. A sealing gasket 10 is provided at one end of joint 2 8 located inside joint 1, and the other end of sealing gasket 10 is rotatably connected to the interior of joint 1. A sealing gasket 2 12 is fixedly provided at one end of flange 11 close to joint 2 8, and the other end of sealing gasket 2 12 is rotatably connected to joint 1.

[0026] Working principle: When installing the device, insert the sealing gasket 10 between the joint 1 and the inner tube 2, then insert the joint 1 and make it press against the sealing gasket 10, and finally insert the sealing gasket 2 12 into the groove under the flange 11, and connect the two flanges with bolts. Then it can be put into use.

[0027] During use, the internal fluid will be blocked by the rubber strip 1 3. At the same time, the internal pressure can also push the rubber strip 2 7 outward until it contacts the limit plate 6. When the rubber strip 2 7 contacts the limit plate 6, the gap between the limit plates 6 will be blocked. Only when the pressure in the device decreases will the rubber strip 2 7 break away from the range of the limit plate 6, and the gap around it allows the fluid to flow back into the pipe, thereby recovering a small amount of leaked fluid.

[0028] If the seals in the device are unable to block and recover the fluid, the second sealing gasket 12 can serve as the last line of defense to prevent the fluid from being directly sprayed out. The second sealing gasket 12 can be tightened by using the two flanges and bolts.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
