Summary of the invention
In order to solve above technical barrier, the purpose of this utility model has provided the rotary joint device of a kind of function admirable, good sealing effect, structure advanced person, double mechanical seal reasonable in design.
In order to realize above-mentioned technical purpose, the utility model has adopted following technological scheme:
The rotary joint device of double mechanical seal, comprise end cap, cylindrical shell, intake pipe and return pipe, end cap is arranged on an end of cylindrical shell, which is provided with water intake, described return pipe rotary sleeve is located in the cylindrical shell, the radial direction through hole that the tube wall of return pipe is provided with, be provided with axial backwater cavity in the pipe of return pipe, described cylindrical shell is provided with backwater mouth, radial direction through hole and backwater mouth are conducted, described intake pipe is set in the backwater cavity of return pipe, and an end of intake pipe connects water intake, and the other end and backwater cavity are conducted.And be respectively equipped with seal ring, wherein left seal ring closed end cap and return pipe, right seal ring closed cylinder and return pipe in the both sides of backwater mouth.
As preferably, be provided with pressure spring between two above-mentioned seal rings.Pressure spring cooperates end cap that two seal rings are compressed, and whole device loading and unloading are easy, increase flexibility.
As preferably, two above-mentioned seal rings are made up of planar seal ring and step seal ring respectively, and planar seal ring is arranged on the inboard of step seal ring, and described pressure spring is against on two planar seal rings.Seal ring is divided into planar seal ring and step seal ring, has characteristics easy for installation.
As preferably, be provided with O-ring seal between above-mentioned planar seal ring and the return pipe, be provided with O-ring seal between step seal ring and cylindrical shell and the end cap.O-ring seal can further seal above-mentioned structure.
End cap of the present utility model links to each other with cylindrical shell, and as the body apparatus of swivel joint, backwater mouth is used to discharge circulating water.Intake pipe is installed in the return pipe and return pipe rotates with crimping wheel under the drive of bearing together, and the processing of lowering the temperature of crimping wheel cooling water is provided.The effect of critical piece is as described below: provide the crimping wheel cooling water by intake pipe, reach cool effect.By return pipe the post-job cooling water of cooling is refluxed, and discharge by backwater mouth.Reach best sealing effect by double mechanical seal, can't make cooling water enter seal arrangement inside and damage swivel joint, durable in use.
The utility model has solved well that old-fashioned in the past rotary joint structure is simple, and sealability is relatively poor, can infilter mechanical seal device and bearing to water in device work, damages the problem of swivel joint.Structure advanced person, reasonable in design, durable in use in the working life of improving swivel joint, has guaranteed the normal operation of producing.
