Abstract
The utility model relates to a heat supply measuring meter, which comprises a flow meter which is connected with a water inlet pipe, and a detection and display device which is positioned above the flow meter and is composed of cells, a printed circuit board, a large scale integrated circuit microprocessor, a liquid crystal display and a signal power supply plug. A permanent magnet is arranged on an impeller of the flow meter; a partition board is positioned above the impeller; a magnetism-sensitive sensor corresponding to the permanent magnet is arranged on the partition board. A water inlet temperature sensor runs through the partition board and is inserted in the flow meter; a water return temperature sensor is connected to the printed circuit board by a cable. The utility model has the advantages of simple structure, accuracy measurement and reliable operation.
Description
The utility model belongs to instrument, more relates to a kind of measurement instrument that is used for the residence heating heat.
The modern management of residential housing heating system needs the actual heating heat of user is pressed the family meterage, and countries and regions such as Europe, Japan, Korea S are carried out already and used the calorimeter accounting management.This heat metering table (abbreviation hotlist), be with water ga(u)ge, hot and cold water pipe temperature probe, electric signal handle, display unit, be installed in respectively into, on the return pipe, be connected to become one with some cables again and overlap the heat metering device.The device that cables this dispersion, connect more, system is huge, and complexity is installed, and is unsuitable for promoting in China's domestic-heating system.
CN2282684Y has announced " integrated meter for heating radiators ", and it is with hot water gauge and testing circuit, and the inflow temperature sensor is loaded in the watchcase, makes integrated gauging table.Though reduced joint than prior art, totally two of cold junction cable for measuring temperature and city's electrical cables.The flowmeter of this " heating meter " still adopts common gear type water meter, mechanical speed change, complex structure, operational reliability is poor, and the electronic component power consumption in the testing circuit of this " heating meter " is big, therefore must adopt mains-supplied, easily artificially cut off the power supply, stopped metering, and easily got an electric shock.
The purpose of this utility model is intended to overcome the deficiency of prior art, and a kind of simple in structure, accurate measurement, true is provided, and reliable heat metering table is more suitable for installing and using in China's heating system.
The utility model is achieved through the following technical solutions its purpose.A kind of heat metering table, comprise: directly manage the flowmeter that is connected with water inlet (hot water), be positioned at detection, the display device of flowmeter top, on the impeller of flowmeter permanent magnet is housed, there is the nonmagnetic substance dividing plate that is connected on the flowmeter shell impeller top, corresponding permanent magnet is installed magneto-dependent sensor on the dividing plate, passes dividing plate the inflow temperature sensor is inserted in the hot water of flowmeter.Detect, display device by built-in battery, the printed circuit board (PCB) that is connected with battery lead, place the large scale integrated circuit microprocessor on the circuit board, LCD that is connected with circuit board and signal, attaching plug composition.Being provided with insulation material layer and plate washer above the dividing plate separates flowmeter and detection, display device.Large scale integrated circuit is selected LY11M15D for use.To place the return water temperature sensor in the backflow water pipe to be connected on the printed circuit board (PCB) with external cable.Detection, display device are installed on the plate washer, and seal with outer cover.
Compared with the prior art the utility model owing to adopted the large scale integrated circuit microprocessor, directly differentiates original flow signal, has replaced mechanic gear mechanism, therefore, not only simplify the structure, and also reliable; Owing to adopted accurate integrated temperature sensor and large scale integrated circuit, guaranteed the accurate of metering; Owing to taked thicker insulation material layer, avoided the influence of high temperature conduction to the circuit elements device, guaranteed the result of use that gauging table is good; Owing to adopted built-in battery, total power consumption is at the microampere order of magnitude, and a batteries can be used more than 3 years, was not subjected to extraneous man's activity, measured true, safe and reliable.In addition, the utility model has only been used a cold junction cable for measuring temperature, and structure is more reasonable.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is detection, display device schematic diagram.
As shown in Figure 1, 2, a kind of heat metering table, comprise the flowmeter 11 that directly is connected with water inlet (hot water) pipe, on the impeller 12 of flowmeter permanent magnet 13 is housed, there is the nonmagnetic substance dividing plate 7 that is connected on the flowmeter shell top of impeller, corresponding permanent magnet 13 is equipped with magneto-dependent sensor 14 on the dividing plate, passing dividing plate inserts inflow temperature sensor 16 in the hot water of flowmeter, sealing ring 9 also is housed between dividing plate 7 and the flowmeter shell, the top insulation material layer 5 and the plate washer 6 of also being provided with of dividing plate 7 is equipped with detection, display device on the plate washer 6.Detect, display device by built-in battery 4, the printed circuit board (PCB) 3 that is connected with battery lead, place the large scale integrated circuit microprocessor 2 on the circuit board, the LCD 1 that is connected with circuit board, and signal, attaching plug 18 compositions.Detection, display device are sealed and dress lead sealing 8 with outer cover 19.To place the return water temperature sensors 20 in the backflow water pipe 21 to be connected on the printed circuit board (PCB) 3 with external cable 15, sealing 17 will be set entering outer cover 19 places.Enter flowmeter in order to hinder the foreign material quarrel grain that may contain band in grade hot water, screen pack 10 is set in the porch.
Large scale integrated circuit is selected for use: LY11M15D LCD 1 is selected 8-10 bit digital display for use, return water temperature sensor 20, and inflow temperature sensor 16 is selected accurate integrated temperature sensor for use; Nonmagnetic substance dividing plate 7 is selected brass or heat resistant plastice for use, and insulation material layer 5 is selected glass fibre cotton for use.
