Abstract
The utility model provides a rotary seal device is used in conduction oil transmission, including move connect with quiet joint, move connect with quiet joint between be equipped with the expansion joint, move to connect and all be equipped with that the graphite winding is sealed fills up on the sealed face relative with quiet joint, the expansion joint connects fixed connection through sealed pad of graphite winding with moving, the joint was moved to the expansion joint orientation one end is equipped with ceramic wear -resisting terminal surface, the sealed pad of graphite winding on the quiet joint is equipped with the ceramic wearing layer of ceramic wear -resisting terminal surface rotation complex with the expansion joint. Adopt ceramic terminal surface rotary seal to being equipped with the expansion joint and providing wear compensation, realize long -term sealing, effectively preventing leakage is safe in utilization, eliminates the potential safety hazard. At textile machinery, especially in the use of scalding the smooth roll, it is very good to prevent revealing the effect.
Description
Technical field
The utility model relates to a kind of conduction oil transmission technology, particularly a kind of conduction oil transmission rotary sealing appts.
Background technology
Conduction oil, for the specialized oil product of a class better heat stability of indirect transfer heat. Because it has homogeneous heating, temperature adjustment precise control can produce high temperature under low-steam pressure, and heat-transfer effect is good, energy-conservation, carries and the feature such as easy to operate, is widely used in recent years various occasions, and its purposes and consumption get more and more. In recent years, in field of textile machinery, especially in the use of ironing roller, generally used heat-conducting oil heating, because being transmits under the condition of high temperature, very high to the seal request in its transmitting procedure, especially at swivel joint place, sealing ring is easily aging, just in case reveal, when conduction oil and naked light meet, likely burn, cause security incident.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, has proposed a kind of effectively preventing and has revealed, and uses safe conduction oil transmission rotary sealing appts.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of conduction oil transmission rotary sealing appts, comprise moving joint and quiet joint, be characterized in: between moving joint and quiet joint, be provided with expansion joint, on the moving joint sealing surface relative with quiet joint, be equipped with graphite and be wound around sealing gasket, expansion joint is wound around sealing gasket by graphite and is fixedly connected with moving joint, expansion joint is provided with ceramic wear-resisting end face towards one end of moving joint, graphite winding sealing gasket on quiet joint is provided with the ceramic wear-resisting end face of expansion joint and rotates the ceramic wearing coat coordinating.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described expansion joint is bellows.
The utility model compared with prior art, adopts ceramic end face rotatory sealing, and is equipped with expansion joint wear-compensating is provided, and realizes long-term seal, can effectively prevent from revealing, and uses safety, eliminates safe hidden trouble.
Brief description of the drawings
Fig. 1 is structure diagram of the present utility model.
Detailed description of the invention
A kind of conduction oil transmission rotary sealing appts, comprise moving joint 5 and quiet joint 1, between moving joint 5 and quiet joint 1, be provided with expansion joint 4, on the moving joint sealing surface relative with quiet joint, be equipped with graphite and be wound around sealing gasket 2, expansion joint 4 is wound around sealing gasket by graphite and is fixedly connected with moving joint 5, expansion joint 4 is provided with ceramic wear-resisting end face towards one end of moving joint, and the graphite winding sealing gasket on quiet joint 1 is provided with the ceramic wear-resisting end face of expansion joint and rotates the ceramic wearing coat 3 coordinating. Described expansion joint is bellows.
Adopt ceramic end face rotatory sealing, and be equipped with expansion joint wear-compensating is provided, can effectively prevent from revealing. In field of textile machinery, especially, in the use of ironing roller, leakage-preventing effect is very good.
