Abstract

The utility model discloses a self-adjusting type machine end face sealed water hinge which comprises a water inlet pipe component, a water return pipe component and a rotating shaft. The water inlet pipe component and the water return pipe component are arranged on the rotating shaft through a sealing mechanism in a rotatable mode. The sealing mechanism further comprises a rotating ring, a stationary ring and a spring seat. The rotating ring is arranged on the rotating shaft through a bearing in a rotatable mode. The stationary ring is movably arranged on the rotating shaft in a sleeved mode along the axial direction of the rotating shaft. The spring seat is fixedly arranged on the rotating shaft and is provided with a spring which enables the stationary ring to be elastically pressed against the rotating ring. A face, adjacent to the rotating ring, of the stationary ring is provided a friction convex face which is contacted with the rotating ring and a concave face which is not contacted with the rotating ring. The concave face is roughly equal to the end face, installed by the stationary ring, of the spring. The self-adjusting type machine end face sealed water hinge is capable of preventing a friction face and an end face of a sealing structure from being influenced by intensity of pressure of inner media.

Description

A kind of water hinge of self-align type mechanical end face seal
Technical field
The utility model relates to a kind of water hinge.
Background technique
The water hinge is the significant components of radar, the rotary joint such as peculiar to vessel, and the pressure that it has the sealing cooling liquid is low, the hinge rotational speed slow, require the characteristics such as good airproof performance, long service life.The cooling medium of water hinge sealing generally is ethylene glycol.
The seal form of existing water hinge mainly contains two kinds: a kind of is flexible sealing, and a kind of is mechanical dynamic seal.Flexible sealing mainly is to seal by rubber ring, and it is simple in structure, and cost is low, but easily wearing and tearing and aging of rubber ring produce and leak, and need often to change seal ring.Mechanical dynamic seal has that sealing is reliable, and leakage rate is little, and long working life, end face can auto-compensations, need not the advantages such as often maintenance, and shortcoming is high to the processing of Sealing and assembly precision, and the manufacture cost height is difficult for when breaking down taking emergency measures.
What the mechanical seal of existing water hinge was generally adopted is the structural type of dynamic and static ring end face seal, nonparallelism when this structure adopts stationary ring that the rotating ring abrasive end face is rotated compensates, with the assurance sealing effect, but can not in compensation, eliminate interior media pressure to the impact of surface of friction pair pressure.When interior media pressure increases, aggravated the loss of rubbing surface, reduced working life.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of water hinge of self-align type mechanical end face seal, can eliminate the pressure of interior media to the impact of surface of friction pair pressure, prolongs the operating life of water hinge.
The water hinge of a kind of self-align type mechanical end face seal of the present utility model comprises: water inlet pipe component, return pipe assembly and rotating shaft, and described water inlet pipe component and return pipe assembly rotatably are installed in the described rotating shaft by sealing mechanism; Described sealing mechanism further comprises: rotating ring, stationary ring and spring seat, rotating ring rotatably is installed in the described rotating shaft by bearing, stationary ring axially movably is sleeved in the described rotating shaft along described rotating shaft, spring seat is fixedly mounted in the described rotating shaft, is equipped with on the described spring seat described stationary ring elasticity is pressed against spring on the described rotating ring; The one side adjacent with described rotating ring of described stationary ring has with the contacted friction convex surface of described rotating ring and the concave surface that do not contact with described rotating ring, and the end face that this concave surface and described stationary ring are installed described spring about equally.
Preferably, the end extension adjacent with described spring seat of described stationary ring is provided with the prolonged section that is embedded in the described spring seat, is provided with seal ring between this prolonged section and the described spring seat.
The nonparallelism when but the utility model stationary ring and spring seat adopt the self-align type structure to rotate rotating ring compensates, therefore the end face of concave surface and stationary ring mounting spring can not guarantee simultaneously that sealing configuration rubbing surface end force is not affected by interior media pressure about equally owing to do not contact with rotating ring.Such mechanism has reduced difficulty of processing, has reduced cost, and is low to working condition requirement, thereby prolonged the operating life of water hinge.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A section structure for amplifying schematic representation of Fig. 1.
Embodiment
As shown in Figure 1, the utility model comprises: water inlet pipe component 3, return pipe assembly 4 and rotating shaft 1, water inlet pipe component 3 and return pipe assembly 4 rotatably are installed in the rotating shaft 1 by sealing mechanism.
As shown in Figure 1, 2, sealing mechanism of the present utility model further comprises: rotating ring 6, stationary ring 7 and spring seat 11, rotating ring 6 rotatably is installed in the rotating shaft 1 by bearing 2, stationary ring 7 axially movably is sleeved in the rotating shaft 1 along rotating shaft, spring seat 11 is fixedly mounted in the rotating shaft 1, is equipped with on the spring seat 11 stationary ring 7 elasticity are pressed against spring 8 on the rotating ring 6.The one side adjacent with rotating ring 6 of stationary ring 7 has and rotating ring 6 contacted friction convex surfaces 12 and the concave surface 13 that do not contact with rotating ring 6, and the end face 14 of this concave surface 13 and stationary ring 7 mounting spring 8 about equally.
In the utility model embodiment, rotating ring 6 forms by being used for contacting the ceramic fitting of sealing and being used for hard-wired stainless steel part with stationary ring 7.
Like this, on the one hand, the nonparallelism when but stationary ring 7 adopts the self-align type structure to rotate rotating ring 6 with spring seat 11 compensates, on the other hand, the end face of concave surface 13 and stationary ring 7 mounting spring 8 is not about equally owing to do not contact with rotating ring 6, even therefore the sealing cooling medium pressure of water inlet component or backwater assembly is very large, the pressure that two faces are subject to can be offset, so that stationary ring 7 just is subject to the elastic force of spring 8 and is pressed against on the rotating ring 6, therefore can guarantee simultaneously that sealing configuration rubbing surface end force is not affected by interior media pressure.
In addition, such mechanism has also reduced difficulty of processing, has reduced cost, and is low to working condition requirement, thereby prolonged the operating life of water hinge.
In addition, an end adjacent with spring seat 11 of stationary ring 7 extends and is provided with the prolonged section 10 that is embedded in the spring seat 11, is provided with seal ring 9 between prolonged section 10 and the spring seat 11.Like this, can eliminate the sealing cooling liquid to the impact between spring seat 11 and the stationary ring 7, guarantee that the power that stationary ring 7 is subject to is the elastic force of spring 8.
By above-mentioned sealing configuration, after advancing the return pipe assembly and relatively rotating, realize cooling liquid the sealing of advancing the backwater assembly and with the sealing of ambient atmosphere.
