Abstract
The utility model provides an improved rotary joint which has long service life, and comprises a housing, a rotary head, a tension spring, an end cover, a spring base and a sealing device; wherein, a liquid channel is arranged in the housing, the end cover can be detachably arranged on the housing, the rotary head can be rotatablely arranged on the end cover, a liquid flowing hole is arranged on the rotary head, the liquid flowing hole is communicated with the liquid channel, the spring base can be rotatablely arranged on the rotary head, the tension spring is arranged between the housing and the spring base, the sealing device is arranged between the end cover and the rotary head, a bearing ring is arranged on the housing, and the axial end of the rotary head can be rotatablely arranged on the radial inner lateral wall of the bearing ring. The improved rotary joint of the utility model is mainly used for the situation of transmitting such mediums as fluid, gas, etc., to a rotary device.
Description
Technical field
The utility model relates to a kind of improvement swivel joint, and it is used for fixing the conveying of medium between portion and the rotary part.
Background technique
Swivel joint has been known, and it is used for liquid or gas are transported to the device that a circumference rotates.With reference to figure 1, known swivel joint comprises housing 1 ', swivel head 2 ', tension spring 3 ', spring seat 4 ', seal arrangement 5 ' and end cap 6 ', be provided with the fluid passage of hollow in the described housing 1 ', described end cap 6 ' removably is located on the housing 1 ', described swivel head 2 ' is located on the end cap 6 ' rotationally, be provided with liquid-through hole in the described swivel head 2 ', described liquid-through hole is connected with fluid passage, described seal arrangement 5 ' is located at and is prevented between end cap 6 ' and the swivel head 2 ' that fed sheet of a media is from leaking between the two, described spring seat 4 ' is located on the swivel head 2 ', described tension spring 3 ' is located at and is made seal arrangement 5 ' continue to keep sealing between housing 1 ' and the spring seat 4 ' when swivel head 2 ' rotates, described seal arrangement 5 ' is generally a graphite ball with sphere, its deficiency of the swivel joint of this kind structure is: have only a supporting part between described swivel head 2 ' and the end cap 6 ', swing easily when being subjected to radial force in the swivel head 2 ' rotary course, this swing will play very big destruction to seal arrangement 5 ', simultaneously when having granule foreign in the fed sheet of a media, its surface of contact that enters seal arrangement 5 ' and end cap 6 ' or swivel head 2 ' will destroy the sealability of seal arrangement 5 ', and then greatly restricts the working life of swivel head.
The model utility content
The purpose of this utility model is to provide a kind of improvement swivel joint of long service life.
The technological scheme that the utility model adopted is such: a kind of improvement swivel joint, comprise housing, swivel head, tension spring, end cap, spring seat and seal arrangement, be provided with fluid passage in the described housing, end cap removably is located on the housing, swivel head is located on the end cap rotationally, swivel head is provided with liquid-through hole, described liquid-through hole is connected with fluid passage, described spring seat is located on the swivel head rotationally, tension spring is located between housing and the spring seat, described seal arrangement is located between end cap and the swivel head, and described housing is provided with bearing ring, and an axial end of described swivel head is located on the radially inner side wall of bearing ring rotationally.
Above-mentioned improvement swivel joint, described seal arrangement are the balls that a side has spherical concave surface.
Above-mentioned improvement swivel joint is provided with stuffing box packing between described end cap and the swivel head, and a gland removably is located at and is used to compress stuffing box packing on the end cap.
Above-mentioned improvement swivel joint, described gland are provided with regulating device and are used to adjust cohesive force between stuffing box packing and the swivel head.
Above-mentioned improvement swivel joint, the described tension spring the other end is located on the bearing ring.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: described swivel head has two radial support positions with respect to housing, when swivel head is subjected to radial force in rotary course like this, the obvious eccentric wear of the unlikely generation of swivel head, seal arrangement is stressed more even, therefore be able to obvious raising the service time of seal arrangement, and then prolong the working life of swivel joint.
