Abstract
The utility model discloses a rotary joint with the advantages of long service life and firm seal, which comprises a casing and a rotating shaft which is connected inside the casing and can rotate. A spring is arranged inside the casing and the spring is abutted against a clamping station of the end port of the rotating shaft; the other end of the spring is pressed against the inner wall of the casing by a driven ball seal; a sealing element is arranged between the rotating shaft and the inner wall of the casing; the sealing element is arranged on the sealing clamping station on the inner wall of the casing which is contacted with the rotating shaft; a nut gland is screwed at the port of the casing; the rotating shaft and the sealing element are relatively and rotationally sealed to form a seal friction pair and the spring is used for compensating at any time so as to play a mechanical sealing effect; and due to the addition of the driven ball seal device, the torque force of the rotating shaft is balanced and the rotating shaft is rotated more flexibly. The loss of a long-term continuous working heat source of enterprise mechanical equipment is avoided, the energy and the equipment maintenance funds are saved, and the benefits are very obvious.
Description
Technical field
The utility model relates to the swivel joint in rubber industry, the plastic industry rubber preparing device cooling procedure, and specifically a kind of life-span is long and seal firm swivel joint.
Background technique
In the present domestic vulcanization of rubber process; Former in the no longer suitable modern continuous work flow process of packing form sealing; The soft alloy flexible pipe has more short shortcoming in existing working life again, and for this reason, necessary moving law and medium situation according to vulcanizer developed a kind of brand-new swivel joint.
The model utility content
The purpose of the utility model is the defective that exists to existing technology, provides a kind of life-span long and seal firm swivel joint, has guaranteed not the losing of long-term continuous operation thermal source of enterprise's machinery, has practiced thrift the energy and plant maintenance fund.
The utility model solves the technological scheme that its technical problem adopted: a kind of life-span is long and seal firm swivel joint; Comprise housing and be connected enclosure interior and revolvable running shaft; Said enclosure interior also is provided with spring and this spring is connected on the running shaft port card platform, and the other end of spring then withstands on the inner walls through driven ball sealing.
Be provided with Sealing between said running shaft and the inner walls.
Said Sealing is arranged on the sealed card platform of the inner walls that contacts with running shaft.
The nut gland has been screwed in said housing port.
A kind of life-span of the utility model is grown and seals firm swivel joint and compares with existing technology, has following beneficial effect:
The utility model adopts novel seal that is fit to medium and the mechanical technology that compensates automatically, makes the sealing position be in the state of closely cooperating forever.The utility model is on former packing_seal form basis; According to the machine movement rule in the vulcanization of rubber process, the binding medium requirement has been adopted wear-resisting novel seal and has been cooperated technology; Design than former packing_seal life-span long more than 20 times product; Guaranteed not the losing of long-term continuous operation thermal source of enterprise's machinery, practiced thrift the energy and plant maintenance fund, benefit is fairly obvious.
Description of drawings
Accompanying drawing is a kind of life-span length of the utility model and the structural representation that seals firm swivel joint.
Among the figure: 1, sealed card platform; 2, Sealing; 3, nut gland; 4, spring; 5, driven ball sealing; 6, running shaft; 7, housing.
Embodiment
Next with reference to Figure of description to a kind of life-span of the utility model long and seal firm swivel joint do below explanation at length.
A kind of life-span is long and seal firm swivel joint; Comprise housing 7 and be connected enclosure interior and revolvable running shaft 6; Said enclosure interior also is provided with spring 4 and this spring is connected on the running shaft port card platform, and the other end of spring then withstands on the inner walls through driven ball sealing 5.Be provided with Sealing 2 between said running shaft and the inner walls.Said Sealing is arranged on the sealed card platform 1 of the inner walls that contacts with running shaft.Nut gland 3 has been screwed in said housing port.
The above embodiment is a kind of of the more preferably concrete mode of execution of the utility model, and common variation that those skilled in the art carries out in the utility model technological scheme scope and replacement all should be included in the protection domain of the utility model.
