Abstract
The utility model provides a quantitative supply device for an IC card water meter, which is characterized in that a valve is movably connected with a piston via a connecting rod; the piston is provided with a telescopic raised head, and an upper clamping hole and a lower clamping hole are matched with the raised head. The starting mode of the raised head is that the raised head is pushed aside via a raised head pushing device; when the raised head be clamped in the upper clamping hole, the valve is in a fully opened state, and water flow quantity at a water outlet part is large; when the raised head is clamped in the lower clamping hole, the valve is in a semi-opened state, the water flow quantity at the water outlet part is small, and at the time, a user is reminded to prepare to change an IC card. The utility model which has simple structure has a predicting function. The utility model relates to an intelligent water meter, which is composed of a meter body, a counting device, a driving device, and an electric control device.
Description
The utility model relates to a kind of water meter, especially a kind of quantitative supply device that is used for the IC-card water meter.
Adopt the purpose of IC-card water meter to realize the regulate charges simplification exactly, using water wisely, but, cause a lot of users owing to do not have good predictor in the IC-card water meter at present, after IC-card used up, tap water was closed suddenly, made troubles to the user.
The purpose of this utility model just provides a kind of water meter quantitative supply device with forecast function.
The utility model has designed a valve, and this valve flexibly connects by a connecting rod and piston; Moving up and down of piston respectively by motor and own wt control.Piston is provided with a telescopic prominent head, and what match with this prominent head is two hole clippings up and down.Should no matter put in that hole clipping by prominent head, piston all can not move.Have only the crown of ought dashing forward to hit device and back down prominent head, piston could move, and it also is two up and down that device is hit on this prominent crown; Corresponding with the position of hole clipping up and down respectively.Two prominent crowns are hit device and are fixed in the rotating shaft, in this rotating shaft with being provided with a gear, the gear coupling mutually in this gear and the water meter.In the time of in the hole clipping above prominent head is stuck in, it is big that valve is in full-gear water delivering orifice place discharge, and when in the hole clipping below prominent head is stuck in, valve is in half-open position, and water delivering orifice place discharge is little, reminds the user to carry out this moment and changes card preparation.Therefore the utlity model has the forecast function.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1, the utility model structural representation.
The structural representation of device is hit on Fig. 2, the prominent crown.
The utility model comprises valve 1, this valve 1 flexibly connects by connecting rod 2 and piston 3, piston 3 is provided with one telescopic prominent 4, for moving of control piston 3, with two hole clippings 5,6 about this prominent 4 having of matching, can hit device 7,8 by the prominent crown respectively and back down when being stuck in hole clipping 5 or hole clipping 6 for prominent 4, the prominent crown is hit device 7,8 and is contained in the rotating shaft 9, and hole clipping 5,6 is corresponding respectively with up and down in its position.Also be provided with a gear 10 in the rotating shaft 9, a gear 11 couplings in this gear 10 and the water meter 12.Moving down of piston is by himself weight realization, moves on it then and risen by motor drives.Device the 7, the 8th is hit on the described prominent crown, is provided with a protrusion on the edge of a round turntable, and described scalable prominent 4 is dops that have spring, and motor is with being connected by lead 13 with piston 3.The utility model principle of work is as follows: when being stuck in 5 li of hole clippings for prominent 4 on the piston 3, piston is in top position, and this moment, connecting rod 2 pind down valve 1, made it be in full-gear, the water delivering orifice aquifer yield is very big, belong to the normal water yield, because current are to flow to for 12 li through water meter, when current are flowed through from 12 li in water meter, its gear 11 must rotate, thereby driven gear 10 rotates, and gear 10 drives rotating shaft 9 rotations, and the rotation of rotating shaft 9 makes the prominent crown that is contained in the rotating shaft 9 hit device 7 and 8 again and rotates.When the prominent crown is hit device 7 and is just gone to the position of hole clipping 5, back down prominent 4, this moment, piston 3 moved down under the effect of own wt, in the time of inside when moving down into hole clipping 6 for prominent 4, because the position that device 8 does not also arrive hole clipping 6 is hit on the prominent crown of this moment, so be stuck in hole clipping 6 the insides again for prominent 4, the valve 1 of this moment is in half-open position, water delivering orifice place discharge is very little, reminds the user to carry out this moment and changes the card preparation.Because when the prominent crown is hit device 8 and forwarded the position of hole clipping 6 to, can back down prominent 4 again soon, piston 3 continues to move down and drives the valve closing current.Want to continue water this moment, must change IC-card and restart motor, by moving on the motor traction piston 3, because the position that device 8 is in hole clipping 6 is hit on the prominent crown, the position that device 7 then is not in hole clipping 5 is hit on the prominent crown of this moment, so piston moves past in the journey last, move past hole clipping 6 very smoothly for prominent 4, be stuck in hole clipping 5 the insides, and when it was stuck in hole clipping 5 the insides, motor stopped also moving.
