Abstract

The utility model discloses a rotary joint in order to solve the problems of easy fracture and short service life of a bearing in the traditional rotary joint during the using process. The rotary joint comprises a flange tee, a spring seat, a spring, an end face sealing ring, a water inlet pipe, a static ring seat and a moving ring seat, wherein the flange tee is arranged at one end of the water inlet pipe; the outer surface of the water inlet pipe is provided with the spring seat; a concave platform is arranged on the spring seat; the spring is sleeved on the outer surface of the water inlet pipe, one end of the spring butts against the concave platform of the spring seat, and the other end butts against one end of the static ring seat which is sleeved on the water inlet pipe; the other end of the static ring seat is connected with the moving ring seat; and the outer surface of the spring seat is sleeved with a plurality of self-lubricating structure bearings in the radial direction. The rotary joint has the advantages of good sealing property, simple structure and long service life, and is easy to manufacture.

Description

A kind of swivel joint

Technical field

The utility model relates to the transmission pipeline of flowing medium and a kind of coupling arrangement between rotating equipment, particularly relates to a kind of swivel joint.

Background technique

At present, the swivel joint effect is in the revolving part of cooling liquid having been imported incessantly and having been discharged by roasting heat, thereby cooling revolving part, it comprises flanged tee, spring seat, end face sealing ring, intake pipe, pressure ring, flange is to make pipe and the interconnective part of pipe, be connected in pipe end, flanged tee is used in the branched pipe place of main pipe, integral body is T-shape, the middle perforation, and the port internal surface is provided with screw thread, flanged tee is used for liquid is shunted more, the bearing of the outer surface setting of the spring seat of existing swivel joint very easily weares and teares and breaks, thereby can destroy the original state of the end face seal of swivel joint inside, can cause like this leaking, reduced working life greatly, existing bearing does not have special structure to avoid this point above yet, if worked in one day 20 hours, use at most and will scrap in 1 year, the material of existing end face sealing ring is a carbon graphite, and quality is softer, and scurf resistance is poor.

The model utility content

Technical problem to be solved in the utility model provides a kind of its inner bearing and is difficult for the swivel joint that is worn and breaks.

In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of swivel joint, comprise flanged tee, spring seat, spring, end face sealing ring, intake pipe, stationary seat, rotating seat, flanged tee is arranged on an end of intake pipe, the outer surface of intake pipe is provided with spring seat, spring seat is provided with concave station, spring housing is contained in the intake pipe outer surface, the one end is against on the concave station of spring seat, the end that the other end is sleeved on the stationary seat on the intake pipe props up, the other end of stationary seat is connected with rotating seat, and the outer surface of described spring seat is set with and radially is being provided with several from moistening the radial bearing of structure.

The outer surface of described spring seat is set with and axially also is being provided with several from moistening the cod of structure.

Described is to be arranged on bearing week through hole on one's body from moistening structure, and fills up oiling agent in the through hole the inside, and this oiling agent is the mixture of graphite and grease.

Described end face sealing ring comprises rotary packing ring and stationary seal ring, and material is cemented carbide.

Radial bearing in the utility model is radially being provided with from moistening structure at bearing, this structure is in the bearing rotation, oiling agent can be along with the rising of temperature, thawing slowly flows out then, and bearing is played good lubrication, because moisten structural distribution certainly on one's body the week of radial bearing, therefore fine to the lubrication effect of whole bearing, bearing will be more durable like this, generally is used in the revolving part of low speed rotation.

Cod in the utility model is for all being provided with from moistening structure on radial and axial, this structure is in the bearing rotation, radial and axial oiling agent can be along with the rising of temperature, thawing slowly flows out then, and bearing is played good lubrication, because moisten structural distribution certainly on one's body the radial and axial week of bearing, therefore fine to the radial and axial lubrication effect of whole bearing, bearing will be more durable like this, is particularly suitable for being used in the revolving part of high speed rotating.

In sum, a kind of rotary joint structure of the utility model is reasonable, and is practical, and physical life is long.
