Problems solved by technology
[0002] Ordinary water joints can connect two or more relatively stationary pipes, but cannot complete the interconnection between pipes that rotate relative to each other
Although the existing rotary water interface device can complete the mutual connection between the pipe fittings with relative rotary motion, it often has poor use effect. The service life of the pair is short and needs to be replaced frequently, which affects the normal use of the rotary water interface device

Embodiment Construction
[0009] The rotating water interface device of the present invention includes a fixed pipe joint 1 and a rotating pipe joint 2 that are connected to each other, and is characterized in that: the outer side of the rotating pipe joint is sleeved with a connecting sleeve 3, and the connecting sleeve is connected to the outer ring of the bearing 4 Fixed connection, the inner ring of the bearing is fixedly connected to the fixed pipe joint, and the butt ends of the fixed pipe joint 1 and the rotating pipe joint 2 are respectively fixedly connected with a static ceramic friction plate 5 and a dynamic ceramic friction disc 5 which are relatively rotating and contact and cooperate to form a sealing surface Friction plate 6.
[0010] In order to keep the contact surfaces of the dynamic and static ceramic friction plates in close fit, and to prevent the liquid from penetrating out and affecting the sealing effect, the fixed pipe joint 1 includes a plug-in tube 7, an elastic sealing sleeve...

The invention relates to a rotary water interface device, which comprises a fixed pipe joint and a rotary pipe joint mutually abutted, the outer side of the pipe joint A is sleeved with a connecting shaft sleeve, the connecting shaft sleeve is firmly connected with a bearing outer ring, a bearing inner ring is firmly connected with the pipe joint B, and the abutting end part between the fixed pipe joint and the rotary pipe joint is respectively firmly connected with a static ceramic friction piece and a dynamic ceramic friction piece with the relative rotary motion and the contact matching in order to form a sealing surface. The device not only improves the sealing effect of the rotary water interface, but also has simple structure and good use effect.
Description
technical field [0001] The invention relates to a rotary water interface device. Background technique [0002] Ordinary water joints can connect two or more relatively stationary pipes, but cannot complete the interconnection between pipes that rotate relative to each other. Although the existing rotary water interface device can complete the interconnection between the relative rotary motion pipe fittings, it is often not effective in use, not only the liquid is easy to seep out from the contact surface, the sealing effect is poor, and the relative rotary motion motion contact The pair has a short service life and needs to be replaced frequently, which affects the normal use of the rotary water interface device. Therefore, designing a rotary water interface device with good sealing effect and long service life has broad market demand and promotion prospects. Contents of the invention [0003] The object of the present invention is to provide a rotary water interface dev...
