Abstract
The utility model relates to a vacuum extractor whose vacuum degree can be regulated. Three way connectors are arranged at the extract opening of an extraction pump, one connector is connected to a voltage-stabilizing storage tank, and the other connector is communicated with the outside atmosphere by four-way through a precise pressure regulator. The vacuum regulator is connected with an interface that is exserted from the voltage-stabilizing storage tank when pumping vacuum from a destination device. The vacuum degree of the destination device can be effectively and stably regulated through regulating the opening degree of the air valve of the precise pressure regulator. The utility model has a negative-pressure adjustable range from 0 to 95 KPa and a negative-pressure adjustable accuracy from 3 up to 5 KPa. The vacuum regulator can meet the requirement of definite destination devices to achieve a certain stable vacuum degree.
Description
The utility model belongs to a kind of vaccum-pumping equipment.
Generally vacuumizing is with vacuum pump certain device to be bled, and wishes that usually degree of vacuum is high more good more, promptly is evacuated to till the maximum vacuum that this vacuum pump can reach always, and does not require that vacuum pump can its extent of evacuation of regulating and controlling.But some destination apparatus operating mode does not also require that degree of vacuum (negative pressure) is high more good more, but requires to be stabilized in certain degree of vacuum, so present various conventional vacuum pump is difficult to finish this task.
The utility model purpose be to design a kind of degree of vacuum can freely regulated vacuum pumping device, by the rate of air sucked in required of a precision pressure regulator bleeding regulating pump, reach the required a certain stable degree of vacuum (negative pressure) of destination apparatus.
The utility model organization plan mainly is made of housing and extraction pump, precision pressure regulator and voltage stabilizing basin.By tee union above-mentioned extraction pump, pressure regulator and voltage stabilizing basin are fused, and be installed on the housing respectively.Because the extraction pump rate of air sucked in required is a rating value, the utility model is regulated rate of air sucked in required from ambient atmosphere by regulating the precision pressure regulator that communicates with ambient atmosphere, with the degree of vacuum of adjusting control target device, it is reached and is stabilized on a certain degree of vacuum.Adopt the voltage stabilizing basin to help degree of vacuum (negative pressure) value of stabilization on destination apparatus.
Description of drawings:
Fig. 1 is a reality air-conditioning regulating device organization plan schematic representation, the meaning of symbol among the figure:
The 1-extraction pump; 2-precision pressure regulator; The 3-tee union; The 4-air outlet; 5-highi degree of accuracy pressure vacuum gauge; 6-voltage stabilizing basin; The 7-working interface; The 8-bleeding point; The 9-housing.
Fig. 2 is the structural representation of precision pressure regulator, wherein symbolic significance:
10-air inflow adjusting screw rod; The 11-main spring; The 12-loam cake; The 13-stopper that reduces pressure; 14-elastic packing pad; The 15-thimble; The 16-relief cock; 17-pays spring; The 18-base; The 19-interface; The 20-suction port; The 21-valve; The 22-air cavity.
Specify organization plan of the present utility model and working procedure thereof with reference to accompanying drawing.It is ZX-0.5 type rotary-vane vaccum pump that extraction pump 1 adopts model, is fixed in the housing 9.Voltage stabilizing basin 6 adopts cylindrical tank, also is installed in the housing 9, has an interface to lead to the housing outside and is connected with destination apparatus.
The organization plan of precision pressure regulator 2 designs voluntarily, as shown in Figure 2.Loam cake 12 is coaxial with base 18, links mutually by screw thread.Flexible gasket seal 14 is equipped with main spring 11 between loam cake and the base above the pad central authorities, and the main spring upper-end surface contacts with air inflow adjusting screw rod 10.Thimble 15 is housed below the pad central authorities, thimble is coaxial with the aperture of decompression stopper 13, thimble passes aperture and contacts with the upper-end surface that the relief cock 16 of paying spring 17 is housed, pay the outside of spring housing in the relief cock lower cylindrical, and be contained in the endoporus of base 18 central projections, the lower end of paying spring rests on the middle terrace of endoporus.
This regulator has two interfaces, interface 20 logical ambient atmosphere; Interface 19 links tee union 3 and is communicated with extraction pump 1 and voltage stabilizing basin 6 respectively.During the work of this device, air inlet adjustment screw rod 10 is turned clockwise, compression main spring 11, elastic force promotes thimble 15 by elastic packing pad 14, thereby valve 21 is opened.Like this, ambient air is given extraction pump 1 air feed through suction port 20, valve 21, air cavity 22 and interface 19.If with the rotation of adjusting screw rod 10 inhour, then valve reduces, until the path of closing with atmosphere.Also be communicated with through pressure reservoir 6 and tee union 3 from destination apparatus with extraction pump 1.So one is the gas of taking out destination apparatus when extraction pump is bled, the 2nd, take out the atmosphere of coming in through precision pressure regulator 2.When reaching to greatest extent as the valve 2 with precision pressure regulator 2, then extraction pump is all bled from ambient atmosphere, does not take out the gas of destination apparatus, and making destination apparatus degree of vacuum (negative pressure) is zero; But valve 21 aperture free adjustment, as valve 21 is turned down gradually, can reduce rate of air sucked in required from ambient atmosphere, and increase rate of air sucked in required gradually from destination apparatus, make destination apparatus add negative pressure gradually, may ultimately reach the desired degree of vacuum of destination apparatus (negative pressure), this negative pressure value can be shown by the highi degree of accuracy pressure vacuum gauge 5 on the voltage stabilizing basin.
The utility model has the advantages that simple in structurely, easy to operate, can guarantee the negative pressure value that provides accurate, stable, to satisfy the destination apparatus operating mode to the requirement of vacuum.
