The invention is the zeroing counter for the volume type flow meter which has convenient, quick and accurate counting without calculation, can directly acquire online continuous metering values and single metering values.
Description
Technical field
The present invention relates to a kind of return-to-zero counter that is applied in the volumeter.
Background technology
Volumeter is made up of flow transmitter and counting mechanism.Wherein, the major part of flow transmitter is measuring room and the sealed coupler that a pair of symmetric rotor is housed; Counting mechanism then comprises reducing gear, precision governor motion, count display and electric pulse sender unit, and count display is called counter again.In some scenarios, not only need measure, also need each single variable, for this reason, single need be set return zero, and keep total accumulative total not return zero for total accumulation.For example, when lorry loading one tank car oil product, finish to can, need directly read this can amount, also will do the record of total integrated flow value simultaneously, to obtain the total oil product granting amount of oil depot accumulative total from the beginning charge of oil.At present, this single that has returns the total accumulative total of zero-sum and does not return zero counter two kinds of forms are roughly arranged, and a kind of is the electronic type return-to-zero counter, and another kind is big character code formula machinery return-to-zero counter.Wherein, the electronic type return-to-zero counter is outer power supply form, and this makes it be subjected to the restriction of on-the-spot power supply restriction and requirement of explosion proof; Big character code formula machinery return-to-zero counter is the double word wheels, promptly always accumulates character wheel group and single accumulation character wheel group and combines, and this makes that the character wheel group is less, is not easy to reading, and the situation that reading is obscured that takes place is often arranged.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of convenient reading, quick, accurate is provided, do not need to calculate, can directly obtaining the volumeter return-to-zero counter of on-line continuous metering numerical value and single metering numerical value.
Technical solution problem of the present invention adopts following technical scheme:

Fig. 1 is transmission principle figure of the present invention.
Fig. 2 is a counter final assembly synoptic diagram of the present invention.
Fig. 3 is a counter cassette mechanism structure synoptic diagram of the present invention.
Number in the figure: 1 counter cover cap, 2 counter housings, 3 minute hand shafts, 4 four paws gears, 5 times zero extension spring, 6 times zero ratchets, 7 minute hands, 8 o'clock needle assemblies, 9 total accumulation character wheel groups, 10 overrunning clutches, 11 connecting cams, 12 handles, 13 reset tension springs.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the total cummulative metering unit that two pointer single flow meterings unit of being made up of minute hand and hour hands is set respectively in the present embodiment, constitutes by the character wheel group, the four paws gear 4 that is connected with the transmission axle of flowmeter speed regulator, and go back to Z-operation mechanism; The drive path of four paws gear 4 is:
Drive path one: the rotation of four paws gear 4 is passed to minute gear Z9 through the minute gear group, and described minute gear Z9 drives minute hand shaft 3 by the overrunning clutch 10 that is in the state of closing and rotates, to minute hand 7 is rotated with minute hand shaft 3;
Drive path two: the rotation of four paws gear 4 is passed to hour hand gear Z13 through the hour hand gear group, needle assemblies 8 when hour hand gear Z13 drives by closing overrunning clutch 10 under the state, and needle assemblies 8 rotates when making;
Drive path three: the rotation of four paws gear 4 is passed to character wheel group 9 through the character wheel gear set;
Going back to Z-operation mechanism is to drive zero ratchet 6 that returns that can swing by handle 12 by returning zero extension spring 5, return zero ratchet 6 and promote the separation of overrunning clutches 10 by connecting cam 11, by connecting cam 11 drive respectively minute hand shaft 3 and the time needle assemblies 8 revolutions in zero-bit.
In concrete the enforcement, corresponding structure is set to:
Constituting of minute gear group: with four paws gear 4 meshed gears Z5, with gear Z5 meshed gears Z6, the gear Z7 coaxial with gear Z6; With gear Z7 meshed gears Z8, described minute gear Z9 and gear Z8 engagement;
Constituting of hour hand gear group: be combined into coaxial, gear Z10 and gear Z11 engagement with the overrunning clutch 10 of minute gear Z9 by being in the state of closing and gear Z10 and minute hand shaft 3 close-fittings; Gear Z11 is coaxial with gear Z12; Described hour hand gear Z13 and gear Z12 engagement;
Constituting of character wheel gear set: the axle head in character wheel group 9 is provided with tooth sector, and tooth sector is coaxial with gear Z7.
Minute hand is set in the present embodiment takes a round, hour hands are walked lattice, and hour hands and minute hand are 1:20; When minute hand moves lattice, numeral of individual position character wheel redirect, pointer and character wheel synchronous operation guarantee the indication of single integrated flux and always accumulate the in full accord, accurate of indicatrix.When the single fluid metering is finished, two pointers return zero simultaneously, and begin the zero point of preparing metering indication next time.When two pointers return zero, always accumulate the character wheel group and do not change, guarantee not changing of total accumulative total.
The course of work:
Overrunning clutch 10 is set under the state of " closing ", at this moment, minute gear Z9 and minute hand shaft 3 are wringing fit, hour hand gear Z13 and the time needle assemblies 8 be wringing fit, the equal clawback of hour hands and minute hand is on zero-bit, character wheel group 9 rests on last total accumulation of measuring when finishing, and waits for metering next time.
Beginning along with this metering of flowmeter: liquid drives the flowmeter internal rotor and rotates, and four paws gear 4 rotates thereupon, through the transmission of each gear set, is realized the metering of this fluid flow realizing cummulative metering once more by character wheel group 9 by minute hand and hour hands.
When flowmeter out of service: minute hand and hour hands all stop on the corresponding scale of counter, can directly read this fluid total volume thus; Total accumulation character wheel group 9 is showing total accumulation.
Return Z-operation: pass through back zero extension spring 5 by handle 12 and drive back zero ratchet 6, return of the separation of zero ratchet 6 by connecting cam 11 promotion overrunning clutches 10, minute hand shaft 3 and minute gear Z9 are broken away from, needle assemblies 8 breaks away from hour hand gear Z13 when also making, by connecting cam 11 drive respectively minute hand shaft 3 and the time needle assemblies 8 revolutions in zero-bit.
When returning zero finishing: the equal clawback of minute hand and hour hands unclamps back zero handle 12 to null position, and reset tension spring 13 will return zero ratchet 6 and retract original position, and overrunning clutch 10 comes back to the state of closing.Returning zero process, because the released state of overrunning clutch 10, all transmission gears are not all participated in rotation, have kept the counting of total accumulation character wheel group 9 constant with this yet.
