A kind of passive oil injection double-screw air compressor temperature-adjusting device, it is provided with oil content oil filter block, be located at the temperature controlled valve core of oil content oil filter block internal cavities and be positioned at the cavity inside of oil content oil filter block and be located at the recovery spring of temperature controlled valve core one end, it also comprises the cavity inside and the temperature-sensitive telescopic element being located at the temperature-sensitive spool the other end that are positioned at described oil content oil filter block, and described temperature-sensitive telescopic element is the temperature sensing spring be made up of temperature sensing material.
As optimization, described temperature sensing spring two ends are flat contact position.
Further, described oil content oil filter block internal cavities is also provided with temperature control valve gap, and described temperature control valve gap coordinates with the internal cavities activity of oil content oil filter block, and is provided with seal ring between described temperature control valve gap and cavity.
Further, described thermostat valve is covered with the toroidal cavity that fitted seal circle is installed; Described seal ring is O-ring seals.
Further, the cavity of described oil content oil filter block is provided with the accent coordinating and load and recover spring, temperature controlled valve core and temperature sensing spring, and inside this accent, place is provided with snap ring groove, and described snap ring groove is provided with snap ring.
Described oil content oil filter block is provided with oil inlet hole and oil outlet, and described oil inlet hole and oil outlet are all communicated with the internal cavities of described oil content oil filter block.
Air compressor, its inside is provided with a kind of passive oil injection double-screw air compressor temperature-adjusting device; Described air compressor is provided with radiator, and described radiator is communicated with the passive oil injection double-screw air compressor temperature-adjusting device of described one.
When ambient temperature has changed, or time the temperature of air compressor itself changes, temperature sensing spring expanded by heating is out of shape, whole temperature sensing spring is made automatically to extend corresponding length according to the temperature of impression, in the process that the continuous expanded by heating of temperature sensing spring extends, suffered by temperature-sensitive spool, the thrust of temperature sensing spring is greater than the thrust recovering spring suffered by temperature-sensitive spool, therefore temperature-sensitive spool moves toward recovering spring direction, after temperature-sensitive spool moves, also the gap between spool bore set by temperature-sensitive spool and oil inlet hole is just changed, oil inlet hole flow is more strengthened, increase radiator to the thermostatic heat radiation of a kind of passive oil injection double-screw air compressor of the utility model, when temperature suffered by temperature sensing spring is when declining, temperature sensing spring expansivity reduces, relatively that temperature sensing spring shortens, in the process that temperature sensing spring constantly shortens, temperature sensing spring reduces the thrust of temperature-sensitive spool, the gap that the thrust recovering spring is greater than between the spool bore set by thrust temperature-sensitive spool of temperature sensing spring and oil inlet hole changes, make oil inlet hole flow less, reduce radiator to the thermostatic heat radiation of a kind of passive oil injection double-screw air compressor of model utility.
And the sealing between temperature control valve gap and cavity makes oil be merely able to flow toward oil outlet direction from oil inlet hole, the phenomenon avoiding leakage of oil occurs.
The beneficial effects of the utility model are: do not need to provide external power supply, have that structure is simple simultaneously, stable performance, temperature degree of regulation are high, long service life, easily to manufacture and advantage that cost is low.
Accompanying drawing explanation
Fig. 1 is the thermostatic structural representation of a kind of passive oil injection double-screw air compressor in the utility model.
Embodiment
As shown in Figure 1, a kind of passive oil injection double-screw air compressor temperature-adjusting device of the utility model, it is provided with oil content oil filter block 1, be located at the temperature controlled valve core 3 of oil content oil filter block 1 internal cavities and be positioned at the cavity inside of oil content oil filter block 1 and be located at the recovery spring 2 of temperature controlled valve core 3 one end, it also comprises the cavity inside and the temperature-sensitive telescopic element being located at temperature-sensitive spool 3 the other end that are positioned at described oil content oil filter block 1, and described temperature-sensitive telescopic element is the temperature sensing spring 4 be made up of temperature sensing material.
As optimization, described temperature sensing spring 4 two ends are flat contact position.
Further, described oil content oil filter block 1 internal cavities is also provided with temperature control valve gap 6, and described temperature control valve gap 6 coordinates with the internal cavities activity of oil content oil filter block 1, and is provided with seal ring 5 between described temperature control valve gap 6 and cavity.
