Abstract
The utility model discloses a full-mechanical preset quantity water meter. A metering mechanism, a quantitative mechanism, an automatic valve closing mechanism and a manual reset mechanism are arranged in a water meter casing, wherein the metering mechanism comprises a fluid driving wheel, a metering wheel system, a metering pointer and a total metering digital wheel group, the quantitative mechanism comprises a directional rotating shaft, a quantitative turntable, a remaining water quantity reading dial and a quantitative spring, the quantitative turntable is provided with a notch, the automatic valve closing mechanism comprises a stop valve core, a reset spring and a guide groove, a guide section and a section of metering lug boss are arranged on the valve core, the manual reset mechanism comprises a reset pull rod group, and the quantitative mechanism is connected with the metering mechanism through a transition gear. When the full-mechanical preset quantity water meter is adopted, the on-demand quantitative water supply and prepayment functions can be realized.
Description
Technical field
The utility model is a kind of measuring fixed amount table, is specifically related to a kind of fully mechanical scheduled volume water meter.
Background technology
Present stage, the water consumption measuring instrument commonly used of China's family expenses mainly is mechanical, needs the manual read to fetch data, and can't realize quantitative water supply.Existing IC-card water meter can realize pre-payment control, but it need rely on power supply, and price is high, has some technical matterss simultaneously.
The utility model content
In view of the problem that above-mentioned technology exists, the purpose of this utility model is: provide a kind of rational in infrastructure, the fully mechanical water meter of quantitative water supply is realized pre paid functionality as required.
The technical scheme that the utility model adopted is: a kind of fully mechanical forward purchasing fixed quantity water meter, comprise water meter case, metering mechanism, quantitative mechanism, valve-closing mechanism and hand-reset mechanism are housed in water meter case, it is characterized in that: metering mechanism comprises that fluid drives wheel, metering train, metering pointer reach metering digital wheel group always; Quantitative mechanism comprises a directed rotating shaft, has quantitative rotating disk, surplus water reading dial and the quantitative spring of breach; Valve-closing mechanism comprises stop valve spool, back-moving spring and gathering sill, and guide section and one section metering boss are arranged on the spool; Hand-reset mechanism comprises the reset lever group, and quantitatively mechanism is connected with metering mechanism by transition gear.
Described quantitative mechanism comprises a directed rotating shaft, has the quantitative rotating disk of breach, surplus water reading dial and quantitative spring.Connect train and metering mechanism by transition gear, train drives by quantitative spring, when the metering train is rotated, quantitatively train drives the quantitative dial rotation in the rotating shaft simultaneously, back-moving spring is with on the boss compression set amount rotating disk on the spool, and after reaching said preset amount of water, boss falls into the recessed breach of taking turns, valve glides, valve-off.The surplus water reading dial both can be used as the demonstration of purchasing the water yield in advance, can inform that again how many water yields the user also has to use.Along with the rotation of rotating shaft, drive the bevel gear rotation, drive the surplus water reading dial then and rotate.
Described valve-closing mechanism comprises stop valve spool, back-moving spring and gathering sill, and guide section and one section metering boss are arranged on the spool.When valve port is operated in full-gear, under the effect of back-moving spring, boss on the spool is crushed on quantitative rotating disk upper surface, when also remaining 11 tons of left and right sides water yields, spool glides along gathering sill, and the boss on the spool is on the breach step that is crushed on quantitative rotating disk under the effect of back-moving spring, turn down valve port, thereby reach forewarning function.When reaching predetermined amount of water, spool under the effect of back-moving spring along the gathering sill close port.
Described hand-reset mechanism is that rod assembly connects with pin with the pull bar group, in the time need resetting behind the valve closing, pull bar packs into the tapered end of spool upper end, and the rotation back moves up along gathering sill, make the valve port standard-sized sheet after, set the forward purchasing water yield, put down pull bar afterwards to desired location.
Described fully mechanical scheduled volume water meter when setting the forward purchasing water yield, drives the rotating shaft rotation with specific purpose tool, makes the surplus water reading dial rotate to the forward purchasing tonnage.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of quantitative rotating disk 12;
Fig. 3 is the sectional view by spool 9.
Wherein 1 is water meter case, and 2 are the fluid drives wheel, and 3 are the metering train, and 4 is transition gear, and 5 is the water meter cap, 6 is directed rotating shaft, and 7 is screw plug, and 8 is quantitative train, and 9 for ending spool, and 10 is case joint, 11 is quantitative spring, and 12 is quantitative rotating disk, and 13 is the spool packing ring, and 14 is back-moving spring.
Embodiment
Embodiment one
As Fig. 1 is structural representation of the present utility model, after the utility model is installed in water system, when working, behind spool 9, special-purpose rod assembly is fixing on water meter cap 5 with special-purpose rod assembly pull-up in elder generation, with specific purpose tool rotating shaft 6, thereby drive the reading dial transition gear, make reading dial rotate to the water yield that the user purchases in advance, put down rod assembly subsequently, boss on spool 9 is pressed in the upper surface of quantitative rotating disk 12 under the acting force of back-moving spring 14; When user's water, current drive 2 rotations of fluid drives wheel, 3 runnings of fluid drives wheel drive metering train also begin metering, by transition gear 4 quantitative train 8 is turned round under the effect of quantitative spring 11, the quantitatively rotation of train 8, drive rotating shaft 6 counter-rotatings, thereby make the counter-rotating of reading dial transition gear, reading dial just can show surplus water; When surplus water reaches 11 tons of left and right sides, glide by spool 9 gathering sill in water meter case 1, the boss on spool 9 on the breach step that is crushed on quantitative rotating disk 12 under the effect of back-moving spring 14, turns down valve port, thereby reaches forewarning function.When reaching predetermined amount of water, spool under the effect of back-moving spring 14 in water meter case 1 gathering sill glide, close port, the utility model quits work.
After a working cycle finishes, the user is if need to continue water, must make house calls by the staff of water-supplying unit, the staff of water-supplying unit purchases the water yield in advance according to the user, opens screw plug 7, with special-purpose rod assembly pull-up behind the spool 9, special-purpose rod assembly is fixing on water meter cap 5, with specific purpose tool rotating shaft 6, makes reading dial rotate to the water yield that the user purchases in advance.
Embodiment two
When metering train 3 was rotated, quantitatively train 3 drove quantitative rotating disk 12 rotations in the rotating shaft simultaneously, as figure
2 and shown in Figure 3, back-moving spring 14 will be pressed in quantitative rotating disk 12 upper surfaces by the boss on the spool 9, when quantitative rotating disk 12 forwards the one-level indentation, there to, valve glides, back-moving spring 14 will be pressed on the breach step of quantitative rotating disk 12 by the boss on the spool 9, when quantitative rotating disk 12 forwarded the secondary breach to, valve glided, automatic-closing valve.
