The utility model relates to a water meter with an IC card mode for a baffle plate opening and closing type valve. An electromagnet, an electromagnetic armature, and a baffle pin form an enclosed cavity in the water meter, and the enclosed cavity is isolated with fluid, and the locking of a valve is controlled by program. The opening and the closure the fluid valve composed of the baffle plate and a baffle ribbed plate do not need electric energy and are realized only by the function of the negative feedback of the fluid, so the energy consumption is little. The volume of the utility model is 1.5 to 2 times as large as the volume of the existing mechanical water meter. A control circuit is installed in the water meter; a water meter casing provided with a liquid crystal display is detachable; the side surface of the water meter is provided with an inserting hole for an IC card, and the side back part is provided with a battery box; if a battery is run out, a user can change the battery lone. The utility model is a novel, small-size, and integrated water meter with an IC card.

Description

The baffle open-close type valve water meter that is used for the IC-card pattern

The utility model belongs to the measuring apparatus of family or industrial enterprise's water rate.

In order to strengthen the management of water resource, it is convenient and reasonable that enterprise and domestic water are paid dues, and reaches effective using water wisely, and development will have wide practical use with the IC-card water meter of developing intellectual resource type, low-power consumption electromechanical integration.For this reason, we investigate and analyze the IC-card water meter product that uses on the market or try out.We have selected four representative tame products: the 1. combined IC card water meter produced of Tianjin Water Group Co., Ltd., 2. the LX1C-15A-25A type IC-card water meter produced of Fuzhou Water Meter Factory, 3. the combined type JB-BIC type IC-card water meter produced of Tianjin Instrument Group Co., Ltd, 4. the CS type IC-card water meter produced of Liangbiao Intelligent Terminal Co., Ltd., Shanghai.Take a broad view of four tame products, its maximum characteristics are to adopt outside fabricated structure, promptly increase control box on the basis of original water gauge.Control box is made up of several parts such as battery, flow sensor, counting circuit, control circuit and solenoid valves.Defective mainly shows: volume is excessive, and inconvenience is installed; Battery power consumption is big, and battery is used and finished, and needs to change by selling the special messenger of water department; The pilot valve bore is little, and is easily stifled during water quality inferiority, influences precision; Selling at exorbitant prices; Steering logic shortcoming etc.

For addressing the above problem the new water meter that the purpose of this utility model provides a kind of small-sized integration, intelligent low-function, environmental protection low price, promptly be used for the baffle open-close type valve water meter of IC-card pattern.

Structural principle of the present utility model as shown in the figure.The baffle open-close type valve water meter that is used for the IC-card pattern has turbo flow meter (1), inductance sensor (2), electromagnet (3) etc., forms an enclosed cavity (6) by electromagnet (3), electromagnet armature (4) and blocking pin (5).By baffle plate (7) with intercept the valve that gusset (8) is formed fluid, and with the inlet pipeline formation inner cavity chamber (9) of fluid.The inclination alpha that intercepts its end face of gusset (8) and inner chamber horizontal axis is 35 degree-50 degree.Baffle plate (7) is fixed on the axle of inner cavity chamber (9) bottom boss (10), and baffle plate can rotate around the axis.Armature (4) left end is fixed in the inwall of enclosed cavity (6), and can rotate around the axis, and right-hand member cantilever, blocking pin (5) and armature (4) axle are connected and are slidingly matched with the circular hole on inner chamber top.When no matter electromagnet armature (4) is picked up or put down by electromagnet (3), blocking pin (5) always keeps vertical movement.The iron core of electromagnet (3) is fixed in enclosed cavity, and turbo flow meter (1) and inductance sensor (2) are loaded in the outer horizontal channel of inner chamber (9) outlet.The proximity inductance sensor is adopted in the conversion of flow and electric weight, and the principle of work of this sensor and duty are similar to the inductive coil of quartz watch.Baffle plate (7) can be metal or the outer injection moulding of metal.Metal baffle (7) I in the closed position no matter, when still being in the open site II, blocking pin (5) has all limited the swing of baffle plate (7).The counterweight of baffle plate and blocking pin, electromagnet armature and the suction of electromagnet are all looked the size of fluid line and are designed.Water meter is whole with smart casting of copper metal or injection molding.Control circuit is loaded on the outer top of outer chamber (5) in the water meter, and LCDs is contained in water meter and covers, and the water meter lid can be for convenience detach, adjusts lead sealing before dispatching from the factory, and the IC socket is left in the side, and trailing flank leaves battery case.The core of control circuit has been selected low-power consumption for use, slept and has waken up formula CPU, and all the other segmentations, counting, storage, demonstration, warning, read-write device all adopt up-to-date little power consumption large scale integrated chip (LSI chip).Adopt No. 1 battery 1-2 joint to power as primary power.When the internal resistance of cell increases to certain numerical value, use 85% o'clock of gross energy as electric energy, user's water is alarm then, when use the battery gross energy 95% the time, then valve closing stops to supply water, flow out corrosive liquids to avoid the energy content of battery to use up, the replacing of battery is undertaken by user oneself.

After the user uses the IC-card payment in advance, insert the IC-card socket (this moment, water swivel was in close valve state) of water meter, under the control of program, electromagnet (3) picks up electromagnet armature (4), blocking pin (5) is upwards mentioned, and baffle plate (7) is fallen the open site II by deadweight by the off-position I, and at this moment blocking pin is fallen by programmed control again, defining baffle swing, the state that fluid line is in often open.When the water consumption of being bought is used up, give alarm during user's water.The leading right to use of arrearage of 5 tons of water of user is given in program design, and after the user purchased water, leading water consumption bales catch removed.5 tons have been reached as the leading amount of user's water, when program is judged the state that water swivel is in out, the control electromagnetic mechanism upwards lifts blocking pin (5), and at this moment baffle plate (7) is owing to can be moved from trend off-position I by the percussive action of current, and blocking pin (5) falls again seals into water.Therefore the open and close of baffle plate all need not electric energy, only depend on the fluid negative feedback, so saved power consumption.

The utility model is reasonable in design, has adopted whole integrated mentality of designing, and volume is 1.5-2 a times of existing machinery formula water meter volume.Become a kind of brand-new, small-sized integrated IC-card water meter, can directly substitute existing machinery formula water meter.Be applicable to enterprise, family, especially commercial residential quarters guarantee that simultaneously the cost cost is lower than present like product.
