Flow control device and coke-oven dust removing system that the controlling method of the flow of flowable substance provided due to the embodiment of the present invention provides with the invention described above embodiment have identical and/or corresponding technical characteristics, so also can produce identical technique effect, solve identical technical problem, so no longer repeat to set forth herein.
As shown in Figure 7, as further improvement of this embodiment, the controlling method of the flow of flowable substance that the present embodiment provides, further comprising the steps of:
S4, add mass 4 on valve 1 as shown in Figure 3;
The method of S5, the weight by changing mass 4 as shown in Figure 3 and/or position is regulated the size of the active force that 4 pairs of valves 1 of mass apply.
By adding mass 4 on valve 1 as shown in Figure 3, can reduce the gap between valve 1 and fluid input 3 in the situation that flow through the constant flow rate of the fluidity substance 10 of fluid input 3, so can pass through the size in gap between the more accurate control valve 1 of size of weight of added mass 4 and fluid input 3, and then control more accurately the flow of fluidity substance 10;
After mass 4 makes an addition on valve 1, the method for weight that can be by changing mass 4 and/or the position of mass 4 is regulated the size of the active force that 4 pairs of valves 1 of mass apply.If mass 4 is while being formed by stacking by a plurality of independently little mass, can reduce or increase by the method for taking away or add the little mass of part the weight of mass 4.If mass 4 be one complete when whole, the method for position that can be by regulating mass 4 is regulated the size of the active force that 4 pairs of valves 1 of mass apply.The said method that the present embodiment provides can utilize valve 1 gravity own to be controlled the size in gap between valve 1 and fluid input 3 fully, overcomes the gravity of valve 1 own without applying external force, so also have advantages of the energy of saving.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
