Abstract
The present invention relates to a two-way filtering cylinder filtering velocity ratio controlling method which provides a two-way filtering cylinder filtering velocity ratio controlling method with low cost and high stability of the filtering velocity ratio. The present invention has the technical scheme that a water inlet pipe is divided into two paths, an upper water inlet pipe and a lower water inlet pipe are respectively connected with a two-way filtering cylinder, and the upper water inlet pipe and the lower water inlet pipe are respectively connected with a flow meter. The present invention is characterized in that the flow meter adopts a volumetric flow meter with a rotor, rotors of two flow meters are connected with the same rotating shaft, and the ratio of the capacities of metering chambers of the two flow meters is the filtering velocity ratio. The present invention has low cost and high stability of the filtering velocity ratio.
Description
The present invention relates to a kind of method of controlling the two-way filtering cylinder filtering velocity ratio.
At present, the control two-way filtering cylinder filtering velocity than making filtering velocity ratio keep stable method to adopt the Single-chip Controlling electric control valve more.The shortcoming of the method is that structure is complicated, the interference of factor such as easily be stressed of filtering velocity ratio stability.
The object of the present invention is to provide that a kind of cost is low, the method for the control two-way filtering cylinder filtering velocity ratio of filtering velocity ratio good stability.
Technical scheme of the present invention: a kind of method of controlling the two-way filtering cylinder filtering velocity ratio, water inlet pipe is divided into two-way, one the tunnel is last water inlet pipe, one the tunnel is following water inlet pipe, last water inlet pipe connects two-way filter tank respectively with following water inlet pipe, and upper and lower water inlet pipe respectively is provided with flowmeter, it is characterized in that: flowmeter adopts the volumetric flowmeter of band rotor, the rotor of two flowmeters and same rotating shaft are conjuncted, make the ratio of volume of two flowmeter measuring rooms be filtering velocity ratio.
Advantage of the present invention: because the present invention adopts the volumetric flowmeter of two band rotors, the rotor of two flowmeters and same rotating shaft are conjuncted, make the rotor of two flowmeters to rotate, thereby make that the ratio of volume of two flowmeter measuring rooms promptly is the filtering velocity ratio of the just upper and lower filter bed water inlet of flow-rate ratio of upper and lower water inlet with same angular speed.Because this filtering velocity ratio is fixed, and can save control elements such as existing single-chip microcomputer, electric control valve, reduced cost, and the filtering velocity ratio good stability is in prior art.
Embodiments of the invention are described in detail in detail in conjunction with the accompanying drawings.
Fig. 1 is a fundamental diagram of the present invention.
As shown in Figure 1, water inlet pipe 1 is divided into two-way, and one the tunnel is last water inlet pipe Q
1, the one tunnel is following water inlet pipe Q
2Water inlet pipe meets two-way filter tank P respectively under the last water inlet pipe, upper and lower water inlet pipe respectively is provided with flowmeter d, x, wherein flowmeter d, flowmeter x adopt the flowmeter of band rotor, can adopt the scraper-type flowmeter during enforcement, the rotor of two flowmeters and same rotating shaft are conjuncted, and at this moment, the ratio of the volume of two flowmeter measuring rooms is filtering velocity ratio.After the ratio of the volume of two flowmeter measuring rooms was set according to needed filtering velocity ratio, when water was pushing away Flux meter rotation, the two-way flow can only be by this fixed ratio with rising or with falling, realizing the control of stablizing filtering velocity ratio.
Claims (1)
1, a kind of method of controlling the two-way filtering cylinder filtering velocity ratio, " filter before water " are divided into two-way and advance two-way filter tank: the one tunnel is advanced into the last filter bed of filter tank under the top of vertical type cylinder shape filter tank through last water inlet pipe, claims this road water inlet to be " go up and intake "; Water inlet pipe is advanced into the following filter bed of filter tank under another road warp from the bottom of filter tank, claim this road water inlet to be " water inlet down ", by last, the water of following filter bed i.e. " filter back water " mixes in the junction of two filter beds and discharges through screen casing, filtering velocity ratio is exactly by last, the ratio of the water velocity in following filter bed cross section, it equals, the ratio of the instant flow of following water inlet, the filtering technique of two-way filter tank requires filtering velocity ratio necessary constant, for this reason, on, following water inlet pipe is respectively established a flowmeter, measure on the filter tank respectively, the flow of following water inlet, deserve to be called, following flow of inlet water meter, it is kept the constant control of filtering velocity ratio and is characterised in that: two flowmeters adopt the volumetric flowmeter of band rotor, the rotor of two flowmeters and same rotating shaft are conjuncted, and rotor is all rotated with same angular speed; And the ratio of the measuring room volume of upper and lower flow of inlet water meter equals the desired filtering velocity ratio of two-way filter tank filtering technique.
