Description
Technical field the utility model belongs to heat energy table technical field, relates to a kind of extensive logical circuit ultrasonic heat energy meter.
The present most heat energy tables of background technology adopt small-bore mechanical type brass hot water gauge as base table, be single channel or multithread bundle hot water gauge flow sensor, among the heat energy table industry standard CJ128-2007 of the Ministry of Construction requirement of flowmeter part also adopted and the identical requirement of existing hot water gauge properties of product basically as the heat energy table.But the practice of operation in recent years shows, directly adopt the flow sensor of small-bore mechanical type hot water gauge as the heat energy table, have that the narrow and initiating flow of range is too big, there are problems such as magnetic interference, high temperature step-out in hot and cold water coefficient of flow difference, magnetic biography mode, causes error in dipping big.Add that the radiator of using in domestic a lot of user family is that the cast iron founding is made, impurity is more, and the wearing and tearing of heat energy table base table are bigger, influence its serviceable life.Therefore, the intrinsic limitation of mechanical type heat energy list structure and principle aspect is difficult in 3 years calibration interval normally, operation accurately.
Utility model content the purpose of this utility model is to solve prior art to have the technical matters that error in dipping is big, serviceable life is short, provides a kind of extensive logical circuit ultrasonic heat energy meter, to overcome the deficiencies in the prior art.
To achieve these goals, the extensive logical circuit ultrasonic heat energy meter of the utility model, form by base table and ultrasonic heat energy meter integraph and temperature sensor, described base table comprises by the straight tube body of stainless steel casting and the entery and delivery port at two ends thereof, the two ends of straight tube body are provided with reflection support and stainless steel mirror reflecting plate, the stainless steel mirror reflecting plate is 45 ° of angle settings, is provided with the ultrasound piezoelectric transducer in the base table die cavity, the ultrasound piezoelectric transducer be installed in reflecting plate above; Described ultrasonic heat energy meter integraph is made up of liquid crystal and large-scale complex Programmable Logic Device plate, is provided with battery case and flow sensor and temperature sensor below the circuit board; Adorn rounded laminar piezoelectric element in the ultrasound piezoelectric transducer, the diameter of piezoelectric element thin slice is 12-13 a times of sheet thickness.
The utility model beneficial effect compared with prior art is:
1, the ultrasound piezoelectric transducer adopts the efficient transducer of low-power consumption, and the piezoelectric element of ultrasonic flow meter transducer is made thin rounded flakes, along thickness vibration.The thin slice diameter surpasses 12 times of thickness, has guaranteed the directivity of vibration, adopts precision die to make transducer enclosure, guarantees that measuring accuracy is not subjected to temperature and pressure variable effect.
2, adopt the large-scale complex Programmable Logic Device to make the ultrasonic heat energy meter integraph, use back the ring technology and strengthen sound path,, improved the survey reason precision of ultrasonic heat energy meter to increase the time difference.
3, because the ultrasound wave that the ultrasound piezoelectric transducer sends can directly reflex on the minute surface of reflecting plate, avoided the dirt deposition on the minute surface effectively, anti-scaling property is good, can guarantee 2 grades of high precision for a long time, be low to moderate most the initiating flow of 1.0L/h, reduced and leaked the generation of counting, counting phenomenon less, guaranteed the rationality of clearing.
4, the dirty degree of monitoring stream quantity sensor and the duty of temp probe automatically, and send early warning.Simultaneously, can adjust the intensity of ultrasonic signal according to monitoring result automatically, the deviation that causes with the influence of the variation that adapts to water quality and incrustation scale keeps the high reliability of operation.When the current bubble exceeds standard, also can give the alarm, and make corresponding adjustment, guarantee that state deteriorating still can reliably working.
5, adopt low power dissipation design, dynamically adjust the ultrasonic measurement frequency according to the flow rate of liquid situation, average current can be low to moderate 28 microamperes, and whole table can use powered battery.
6, base table adopts the straight length design, interior dress reflection support, highly versatile.
7, adopt stainless steel to make the flowmeter base table, with respect to the basis brass material, heavy metal free pollutes.
Appended drawings is the utility model structural representation.
1 is dial plate among the figure, the 2nd, and large-scale complex Programmable Logic Device plate, the 3rd, water inlet, the 4th, ultrasound piezoelectric transducer, the 5th, water delivering orifice, the 6th, flow sensor and temp probe, the 7th, battery case, the 8, the 9th, stainless steel mirror reflecting plate, the 10th, straight tube body.
Embodiment with reference to the accompanying drawings, it is made up of the utility model base table and ultrasonic heat energy meter integraph, base table comprises the entery and delivery port 3,5 by the straight tube body 10 of stainless steel casting and two ends thereof, the two ends of straight tube body 10 are provided with reflection support and stainless steel mirror reflecting plate 8,9, the stainless steel mirror reflecting plate is 45 ° of angle settings, be provided with ultrasound piezoelectric transducer 4 in the base table chamber, the ultrasound piezoelectric transducer be installed in reflecting plate above; The ultrasonic heat energy meter integraph is made up of dial plate 1 and large-scale complex Programmable Logic Device plate 2, is provided with battery case 7 and flow sensor and temp probe 6 below the circuit board 2; Adorn rounded laminar piezoelectric element in the ultrasound piezoelectric transducer, the diameter of piezoelectric element thin slice is 12-13 a times of sheet thickness.
Can be used for heating user's the metering of the utility model heat energy table.Be to launch ultrasound wave mutually by two transducers in the base table, sound wave can be accelerated to propagate when downbeam, and sound wave can delay transit when countercurrent direction.The user is consumed in the certain hour heat and the temperature difference and the flow that advance between the backwater in this section period are proportional, utilize the mistiming between the concurrent-countercurrent can converse the flow velocity of liquid, thereby calculate the flow of hot water.The utility model heat energy table is the precision height not only, and overload capacity is strong, and stability and enduring quality are good, and standard machinery formula heat energy table generally has only 3 class precisions, and precision is relatively poor lastingly.Large-scale complex Programmable Logic Device ultrasonic heat energy meter has minimum life-cycle costing, and maintenance cost is also lower.The utility model develops in a healthy way to promoting heat energy table manufacturing industry, for energy savings, builds a conservation-minded society, and has active operation significance.
