First working state: closed condition
Spool was positioned between top exhalant canal B and second water channel (12) and was communicated with this moment, this is that handle position is made a detour on the off-position, fix with sealed screw (22) at second water channel (12) two ends and seal, be communicated with between intake tunnel A and second water channel (12), the F3=F2 total pressure head is F1-FK (valve core spring power)=F3 during beginning, being communicated with back F1=F2 total pressure head between intake tunnel A and second water channel (12) is that F1+F5-F3 pressure reduction is big, spool diminishes toward moving down F3, the pressure reduction of F3 and F2 increases gradually and closes, close back power W1=F1 (influent pressure) * 3.14R2 (water pipe radius)+F5, block current.
Second working state: opening state
This moment, the described intake tunnel first water channel A (18) closed, be communicated with between the first water channel B (18) and second water channel (12), this period, F3=F2 was near 0, spool up moves opens valve, at this moment fluid resistance W2=F1 (influent pressure) * 3.14R2 (water pipe radius)-F5, the big small valve core of water flow was also moving up and down during spool water flow through, prevent spool do not use for a long time form incrustation scale and, cause the inflexible problem of switch.
The 3rd working state, this moment, described second water channel all communicated with described first passage with described the 3rd water channel 10, and described intake tunnel first water channel A and the exhalant canal first water channel B are connected;
The 4th working state: the effect of safety check (unidirectional)
This moment, water intake hydraulic pressure was less than water outlet hydraulic pressure, F1＜F3, spool is positioned between described intake tunnel B and second water channel (12) and is communicated with, the F3=F2 total pressure is that the pressure reduction of F2+F5 (valve core spring power 4) this period is F3+F5-F1=F5 F3＞F1 at this moment during beginning, spool is toward moving down, the pressure reduction of F1 and F2 is closed after increasing, and power W=S6 after closing (S6: spool top area)+F5-F1 * S5 (S5: the spool lower curtate gross area) block current.
The 5th working state: the location opens or closes
Shown in figure two, this moment described rotary valve rod handle position figure two in the location supply water or locating closing, under closed condition, handle forwards that it is closed condition all the time on the water supply position, location to; Under opening state, handle forwards that it is opening state all the time on the water supply position, location to.
The 6th working state: weighing apparatus is pressed and is supplied water
This moment, the weighing apparatus of described figure three was pressed the water supply principle, and area S1, the S2 of water inlet exhalant canal (18) A, B are numerical invariants, but and Δ S1 and Δ S2 are parameters.Suppose that the constant Δ S1/ of pressure of supply water F1 Δ S2=K handle " opens " and pressure reduction K≤1 when turning the position down at figure two, handle is K 〉=1 when figure two " pass " and pressure reduction are turned the position down, the valve weighing apparatus is pressed water inlet A, water outlet B when supplying water, the second channel of valve rod (12) all-pass, F1 is by water inlet A channel supercharging F2, and F2 reduces pressure by water outlet B passage, produce F1, F2, F3 different pressures effect, form a pressure balance simultaneously, adjust K and can mix up the required discharge pressure F3 of client, adjusted F3 does not change pressure easily.
Weighing apparatus presses the water supply principle shown in figure three, F1; Intake pressure.F2; The spool pressurized.F3; Discharge pressure.S1, S2; Water inlet, the exhalant canal caliber.Δ S1, Δ S2; Water inlet goes out water regulating valve bore (variable).Supposing that intake pressure F1 is constant, utilize and regulate Δ S1 that Δ S2 ratio is regulated F3, is to reach the purpose of regulating F2.
When the A water consumption increases:
F3 diminished when water consumption increased, and it is big that the pressure reduction of F2 and F3 becomes, the power of former F1 overhead-valve core bottom; W6=F2 * R2 (spool top radius) * 3.14+F5 (valve core spring power 4)=F1 * R2 (spool bottom radius) * 3.14, the F2 decompression is that W6 〉=F2 * R2 (spool top radius) * 3.14+F5 (valve core spring power 4) causes pressure balance to destroy, spool up moves the increase flow, boost pressure, pressure forms a new pressure balance again when reaching required discharge pressure F3, though at this moment flow increases variation in pressure (when being no more than the flow of this pipeline).
When the B water consumption reduces:
F3 increased when water consumption reduced, and it is big that the pressure reduction of F2 and F3 becomes, former F1 overhead-valve core bottom power; W6=F2 * R2 (spool top radius) * 3.14+F5 (valve core spring power 4), it is that F2 * R2 (spool top radius) * 3.14+F5 (valve core spring power 4) 〉=F6 causes pressure balance to destroy that the F3 increase causes F2 also to increase, spool is toward moving down the minimizing flow, reduce pressure, pressure forms a new pressure balance again when reaching required discharge pressure F3, at this moment water flow reduces and variation in pressure, and characteristics are setting pressure-be not subjected to influences of flow.
The forbidden zone explanation
Handle is K 〉=8 when position, figure two forbidden zone, the water inlet A standard-sized sheet of valve, and water outlet B opens 1/8, and valve one is opened F3 and is increased, and the small increase of F3 causes spool top power F2 * R2 (spool top radius) * 3.14+F5 (valve core spring power 4) to increase, and causes closing; F3 begins to diminish, and spool rises again, opens valve, is the wild effect of 20-30 switch in the valve per second.
The working principle of novel valve is shown in figure four
Energy when utilizing fluid to flow closes and closes, and non-return is regulated the effect of pressure, and the control valve in-core is pressed the water inlet and outlet caliber Δ S1 of F2, and Δ S2 is the 1/15--1/20 of former valve
Described valve relies on fluid stream to press first stress surface in the active force district active force that makes progress to overcome the gravity of spool self to spool stream, and the pressure of water backs down in the valve pocket, spool between intake tunnel and exhalant canal comes Open valve, by second channel and the first passage water filling in valve pocket that is communicated with, rely on the pressure of water in the valve pocket to make spool block intake tunnel and the exhalant canal throttle down that communicates.This unlatching or the mode of closing do not need manpower to remove to overcome the pressure of fluid, as long as use the working state of very little power conversion valve rod just can open or throttle down.Also need just can open or close for large-scale valve, overcome the difficulty of artificial in the past unlatching or throttle down, the drawback that labor intensity is big by instruments such as spanners.Influent pressure F1, piston press F2, water outlet pressure F3, and changing F2, F3 easily under the stable situation of F1 is again a pressure regulator valve.Based on its structure characteristic, fluid can only a direction flow a suitable again safety check.
More than disclosed only be several specific embodiment of the present invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop in protection scope of the present invention.
