Abstract
The utility model relates to a low temperature carbon ring seal device. The device comprises a metal heating ring arranged inside or outside a device body, wherein an electric heating pipeline connected to the outside of the heating ring is embedded into the metal heating ring; and the electric heating pipeline is connected with a heating power supply. By arranging the metal heating ring, the environment temperature of a carbon ring seal is subjected to heating regulation, and conduction is performed by the heat conductivity of metal, so that the normal operation of the carbon ring seal in a low temperature environment is realized.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically is a kind of carbocyclic ring seal arrangement that can carry out work under low temperature environment.
Background technique
The carbocyclic ring sealing belongs to a kind of of floating seal, the structure of carbocyclic ring sealing comprises ring packing cavity and annular sleeve, circular groove is arranged in the seal chamber, the annular graphite-seal ring that two cross sections are rectangle is housed in the groove at least, have the gap between the internal diameter of graphite-seal ring and the annular sleeve, sleeve outer surface scribbles wearing layer.The carbocyclic ring sealing is simple owing to possessing operation and maintenance, and therefore the advantage of good airproof performance all is used widely in many fields such as oil, chemical industry, petrochemical industry, metallurgy, and the temperature range of its use is-120 ℃ to 500 ℃.
The carbocyclic ring sealing relatively is applicable to the elevated-temperature seal occasion, if use in subzero 120 ℃ low temperature seal occasion.The carbocyclic ring self-enrichment is reduced, and influence cooperates with axle, does not reach desirable sealing effect.
Therefore existing carbocyclic ring seal arrangement is not suitable for low temperature seal.
The model utility content
It is a kind of in subzero low temperature seal occasion below 120 ℃ that technical problem to be solved in the utility model is to provide, and still can realize the carbocyclic ring seal arrangement of good seal performance.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of low temperature carbocyclic ring seal arrangement comprises that one is arranged on the inner or outside METAL HEATING PROCESS ring of this device body, and described METAL HEATING PROCESS ring inside is embedded with the electric heating pipeline that causes the heating ring outside, and described electric heating pipeline connects heating power supply.
As one of preferred embodiment of the technical program, described METAL HEATING PROCESS ring is aluminum heating ring or copper heating ring.
As the further improvement of the technical program, described METAL HEATING PROCESS ring set hoop is on the exterior periphery of carbocyclic ring sealing seat.
Perhaps, described METAL HEATING PROCESS ring is placed between the inner adjacent carbocyclic ring of carbocyclic ring seat.
Also as the further improvement of the technical program, described electric heating pipeline is an electrical heating wire.
In addition, this device can also include temperature controlling instrument, and described temperature controlling instrument is used for controlling the target heating-up temperature of described METAL HEATING PROCESS ring.
Adopt the low temperature carbocyclic ring seal arrangement of technique scheme, by setting up the METAL HEATING PROCESS ring ambient temperature of carbocyclic ring sealing is carried out heat regulation, and utilize the thermal conductivity of metal to conduct, thereby realized the proper functioning of carbocyclic ring sealing under low temperature environment.

Embodiment
The utility model relates to a kind of low temperature seal structure, at the increase of subzero 120 ℃ of low temperature situations to seal request, on traditional carbocyclic ring sealing basis heating ring is set.
Embodiment 1:
Carbocyclic ring seal arrangement as depicted in figs. 1 and 2, adopt the form of external heating ring, on the exterior periphery of carbocyclic ring sealing seat 6, form with anchor ear disposes heating ring 1(aluminum annulus), and tighten up fixingly by bolt 12, heating ring 1 inside is furnished with electric heating pipeline (being heating wire 11), heating wire 11 causes the outside, connect and to add the heat control power supply, supporting terminal box is provided with temperature controlling instrument simultaneously, is used for showing temperature, control temperature, default heating-up temperature.
A carbocyclic ring 4 and axle 3 Spielpassung, the heating by heating ring 1 and through the transmission of heat of its metallic aluminium keeps the temperature requirement of sealing configuration.
Embodiment 2:
As shown in Figure 3 and Figure 4, be built-in heating ring, heating ring 2 is installed in the carbocyclic ring seat 5, and heating ring is placed between two adjacent carbocyclic rings 4, and heating wire 21 outer connected control systems are controlled data such as heating-up temperature or target temperatures.
The heating ring of the sealing device that the utility model provides can be made into the form of built-in heating ring or external heating ring according to heating area.And regulate the heating ring setting temperature according to the actual serviceability temperature in scene, to reach both balances, carbocyclic ring is worked under optimum working temperature, thereby reach the optimal seal effect.
In addition, this METAL HEATING PROCESS ring also can be made by the copper material that is beneficial to conduction, because aluminum material conductivity and cost all have advantage, and therefore preferred here aluminum heating ring.
