Description
Technical field
The present invention relates to a kind of temperature-control circuit for the production of line hot water cyclesystem.
Background technology
In the production technology of fiber secondary coating, PBT (polybutylene terephthalate) plastics of optical fiber loose tube material be a kind of can the thermoplastic of thermoforming, belong to semi-crystalline material, there is high-fire resistance, toughness, fatigability, at low temperatures can crystallization rapidly, crystallinity can reach 40%, and PBT plastic has shrinkability under the influence of the temperature, certain impact can be produced on optical fiber excess length, even cause the increase of optical fiber added losses; How obtaining high-crystallinity is the key that production process controls.
When entering hot water storgae after PBT material is extruded from head, viscous state during its melting changes elastomeric state into, and PBT plastic declines rapidly from molten condition temperature; PBT beam tube has enough crystallization process in the environment of the glass temperature (40 DEG C ~ 45 DEG C) higher than PBT, and the lattice trend formed between interior molecules in drawing process just can be compensated, thus eliminates contraction internal stress; Add PBT plastic self waste heat, this district's water temperature is between 45 DEG C ~ 65 DEG C, result proves: PBT pipe in secondary coating technique as far as possible crystallization obtain more fully, by stablizing high hydrothermal area's temperature, to reduce extrusion molding post shrinkage, in PBT beam tube forming process, crystallinity is higher, and in beam tube, excess fiber length is the most stable.
Existing boiler adopts ball-cock assembly liquid level (mechanical type) to control water inlet, and ball-cock assembly is the reduction and the rising that are subject to the ball float water surface, goes the unlatching or the closedown that control water intaking valve.When the water surface in water tank declines, the ball float water surface also declines, so ball float declines, relies on leverage that valve opening degree is increased, strengthens output.Otherwise ball float all will float on waterborne all the time, when the water surface goes up, cursory also and then rising, stops water when rising to certain position, and water tank frequently retaining makes movable connecting rod easily occur stuck and damage, and causes retaining out of control.And to be armrest the move type of heating operation of the water temperature of boiler, and in reality, adding PBT plastic self waste heat, hot water storgae water temperature is usually between 45 ~ 65 DEG C, higher than the glass temperature (between 40 ~ 45 DEG C) of PBT plastic, the water temperature in boiler is wayward.
Regrettably, in common secondary coating technique, the temperature residing for PBT beam tube and be all not enough to ensure sufficient crystallization process by the time.And after PBT beam tube enters cold rinse bank, Yin Wendu is far below the glass temperature of PBT, thus crystallization process almost stops.Therefore after secondary coating tube is made in a period of time, PBT beam tube also can continue crystallization lentamente, finally reaches its crystallization equilibrium degree, and this just causes the extrusion molding post shrinkage of PBT beam tube, thus beam tube is shortened further at length direction, optical fiber in beam tube more than long to increase.
