Description
Technical field
The utility model belongs to sewage-treatment plant, and particularly a kind of valve block formula becomes the aperture flow control valve.
Background technique
The technological method of Sewage Biological Treatment mainly contains aerobic and anaerobic bio-treated two big classes, general sewage disposal process all relates to the aerobe processing procedure, after utilizing blower fan with air compression (generally about 0.65Kpa), by air distributor even air is distributed to the aerobic zone of biological tank, to the biochemical reaction process oxygen supply, what of air demand will be adjusted according to the aperture that the testing result of dissolved oxygen concentration in the biological tank is controlled air flow rate adjustment valve, promptly guarantee to have enough oxygen supplies, be unlikely the excessive water surface that overflows of air mass flow again and cause waste, the aerobe processing procedure obtains the energy that pressurized air consumes and accounts for more than 50% of entire sewage processing procedure total energy consumption, therefore how the control effect of air mass flow is with energy-saving and cost-reducing in close relations, be the important step that reduces operating cost, select air flow rate adjustment valve for use and select for use a high performance blower fan of equal importance.At present, in the sewage treatment implementation process, often selecting for use of air flow rate adjustment valve ignored by everybody, relate to both air flow modulation in the aerobe processing procedure and belong to low differential pressure, big discharge pattern (several kilosteres of air mass flow/hour, before the valve, pressure reduction is less than 0.2KPa behind the valve), require the modulating valve pressure drop low, the flow adjustable extent is big, adjusting function will be got well, and generally adopts butterfly valve to make modulating valve at present, only can satisfy the low requirement of pressure drop, the flow adjustable extent is little, adjusting function is bad, and butterfly valve has fast katal, is the logarithmic curve type, only in the very little scope of aperture, could make modulating valve and use, make switch valve for industrial and use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of flow adjustment range big, and the valve block formula that adjusting function is good becomes the aperture flow control valve.
The technological scheme that the utility model technical solution problem adopts is: a kind of by stepper motor, the valve block formula that valve seat and valve gap are formed becomes the aperture flow control valve, be characterized between valve seat and valve gap, being equipped with versatilely the multi-disc valve block, the right side, valve block upper end is provided with the valve block locating stud, the valve block locating stud is placed in the positioning groove of establishing on the valve seat, the left side, valve block upper end is provided with the valve block drive pin, the valve block drive pin is through in the valve block drive pin slideway of establishing on the driving plate versatilely, valve block drive pin slideway is made arc, and be evenly distributed on the circumference of driving plate, the driving plate circumferential edges is fixed one and is driven bobbin, driving bobbin is contained in the shift fork versatilely, a shift fork nut is fixed in the shift fork upper end, the shift fork nut is threaded with drive screw, and drive screw is connected with the stepper motor shaft with shaft coupling; Shift fork is provided with the hole, is installed with a guide rod in the hole versatilely, and guide rod is fixed on the gearbox casing; Valve block is made boots shape.
The beneficial effects of the utility model are: this modulating valve forms the variable aperture medium channel by the valve block rotation, and pore size is corresponding mutually with rate-of flow, all can effectively control in 0～100 ℃ of aperture scope, and linear relationship is good, does not have to lag behind; Having center properties of flow, medium in the all-range scope, to scratch the noise that forms after by valve little; This modulating valve flowing medium droop loss is minimum, power consumption is low; Because becoming aperture change rate-of flow is that a kind of mechanical means is realized, does not need adjustment, calibration, reliable performance in the using process.
