Further, described soft sealing gland is ring-like, at the annular groove be provided with for installing ring-like soft sealing gland that quartz sleeve inwall is corresponding.
Further, described iris suitable for reading is dismountable is arranged on extension tube upper end.
Further, described annular sealing gland unit comprises the tracheae that pore and pore that extension tube is arranged are installed; Described tracheae is provided with under meter.
Further, described pore at least arranges two, and is separately positioned on the different positions of extension tube circumferential direction.
Further, described quartz sleeve and extension tube that it is arranged one-body molded.
Relative to prior art, a kind of major diameter fluctuation prefabricated stick drawn wire tightness system described in the utility model has following advantage:
1) in quartz sleeve, setting has good expansile soft sealing gland, plays first step seal protection; The iris suitable for reading arranged makes the gap between prefabricated rods and iris suitable for reading minimize, and plays second stage sealing function; Add a road shielding gas at iris and quartz sleeve junction, further enhance the stopping property of fiber drawing furnace, play third stage sealing function.When ensure that major diameter fluctuation prefabricated stick drawn wire by these three grades of tightness systems, gas stream in the stove and warm field is stable, avoids the oxidation of graphite piece in stove, substantially prolongs its work-ing life, improve fiber strength.
2) what soft seal was firm is arranged in the annular groove of quartz sleeve, easy for installation, and ensure that soft seal is installed accurately, sealing is reliable.
3) iris suitable for reading arranged can regulate internal diameter size according to preform diameter, can adapt to the prefabricated rods of different diameter.

Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of major diameter fluctuation prefabricated stick drawn wire tightness system, as shown in Figures 1 to 3, comprises the quartz sleeve 3 and the interior soft sealing gland 4 of installing of quartz sleeve 3 that are arranged on fiber drawing furnace 8 mouthfuls; Described quartz sleeve 3 top is provided with extension tube 6; Described extension tube 6 is provided with annular sealing gland unit and the adjustable iris suitable for reading 5 of internal diameter.
It should be noted that, quartz sleeve 3 is made by quartz-like material, has resistance to elevated temperatures.In addition, quartz sleeve 3 internal diameter is slightly larger than the maximum diameter of prefabricated rods 2.
Wherein, described soft sealing gland 4 is ring-like, at the annular groove be provided with for installing ring-like soft sealing gland 4 that quartz sleeve 3 inwall is corresponding.
Usual soft sealing gland 4 adopts high temperature resistant, expansive material, as high temperature resistant in used, and the Web materials of the rope of diameter less than 10 μm composition, there is good swelling property, to realize good sealing effectiveness after heating.
Wherein, described iris suitable for reading 5 is dismountable is arranged on extension tube 6 upper end.It should be noted that, as shown in Figure 4, iris 5 suitable for reading is just as camera aperture, and be made up of multiple overlapped arc slim vane, the clutch of blade can change the size in central circular aperture; During use, can regulate the size of internal diameter by rotating the handle that iris 5 suitable for reading is arranged, its adjustment process is similar to camera focus operation, because prior art is more common, just repeats no more here.The maximum diameter of iris 5 central round orifice suitable for reading is greater than the maximum diameter of prefabricated rods 2, and minimum diameter is for until can reach and close completely.Meanwhile, iris 5 suitable for reading selects resistant to elevated temperatures non-metallic material to be made usually.
Wherein, described annular sealing gland unit comprise on extension tube 6 arrange pore 7 and pore 7 on install tracheae; Described tracheae is provided with under meter.
Wherein, described pore 7 at least arranges two, and is arranged on the different positions of extension tube 6 circumferential direction, and in order to reach good sealing gland effect, hole diameter is preferably about 6mm.
Wherein, described quartz sleeve 3 with its on the extension tube 6 that arranges one-body molded.It should be noted that, the internal diameter of quartz sleeve 3 is determined by prefabricated rods 2 maximum diameter, and its annular groove degree of depth of installing soft sealing gland 4 is determined by soft sealing gland thickness and swelling property.
During assembling, soft sealing gland 4 is filled in equably in quartz sleeve 3, then iris 5 suitable for reading is arranged on above quartz sleeve 3 top extension tube 6, then iris 5 suitable for reading is adjusted to maximum diameter.
Before non-wire drawing, prefabricated rods 2 is inserted this tightness system by iris 5 suitable for reading, and outside stayed by prefabricated rods tail pipe 1, afterwards iris diameter suitable for reading adjusted to bigger prefabricated rods 1-2mm, opens annular sealing gland unit, prepares wire drawing.
During wire drawing, if find, naked fibre fluctuation becomes large, rule of thumb can adjust the diameter of iris 5 suitable for reading or adjust annular sealing gland unit of flow size.
It should be noted that, annular sealing gland unit can completely cut off entering of iris 5 extraneous air suitable for reading, slightly lowers the temperature can also to this tightness system simultaneously.
The tightness system simplicity of design that the utility model provides, whole plant cost is very low, but thoroughly solves a large size fluctuation prefabricated rods sealing difficult problem.After taking above scheme, increased substantially efficient attenuation, fiber strength when ensure that fluctuation prefabricated stick drawn wire, gas stream in the stove and warm field stable, and extend graphite piece work-ing life, reduce the production cost of optical fiber, there is larger application value.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
