Problems solved by technology

At present, the rotary joint is widely used to connect the cooling water pipe and the continuous casting roll. Due to the thermal expansion of the continuous casting roll and the vibration during the casting process, the sealing surface of the ordinary rotary joint cannot be perfectly fitted, which leads to the leakage of cooling water.

Embodiment Construction

[0011] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0012] Such as figure 1 As shown, a rotary joint with a shock absorbing structure includes a housing 1, an outer tube 2 and a transition sleeve 3, one end of the outer tube 2 is set in the housing 1, and the other end of the outer tube 2 is sleeved in the transition sleeve 3 , there is a gap between the outer tube 2 and the transition sleeve 3. At the joint between the outer tube 2 and the transition sleeve 3, a step 21 is provided on the top of the outer ring of the outer tube, and two annular concave holes are provided on the outer surface of the outer tube 2. Grooves, O-rings 4 are arranged in each annular groove.

[0013] The gasket 5 between the outer tube and...

Abstract

The invention provides a rotating joint with a damping structure. The rotating joint with the damping structure comprises a shell, an outer tube and a transition sleeve. One end of the outer tube is mounted in the shell in a sleeved mode, the other end of the outer tube is mounted in the transition sleeve in a sleeved mode, a clearance is reserved between the outer tube and the transition sleeve, a step is arranged on the top of the outer circle of the outer tube and at the matching position of the outer tube and the transition sleeve, a plurality of annular grooves are formed in the outer surface of the outer tube, and an O-type ring is arranged in each annular groove. The rotating joint with the damping structure is good in sealing performance, capable of avoiding cooling water leakage, and stable and efficient in work.

Description

technical field [0001] The invention relates to a rotary joint with a damping structure, which belongs to the field of iron and steel casting. Background technique [0002] The steel billet of the steel continuous casting machine works continuously above 1000 degrees Celsius. Excessive temperature affects the service life of the continuous casting roll. There must be a rotating and hollow device to deliver cooling water to the continuous casting roll to ensure the normal operation of the equipment. . At present, the rotary joint is widely used to connect the cooling water pipe and the continuous casting roll. Due to the thermal expansion of the continuous casting roll and the vibration during the casting process, the sealing surface of the common rotary joint cannot be perfectly fitted, which leads to the leakage of cooling water. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide ...
