It features that an electric heater connected to kilowatt-hour meter is arranged in said heating and warming water tank, the thermometer is arranged at water inlet and outlet of said heating and warming water tank, and the water in water tank is circulating between the heating and warming water tank, the calorimeter and the heat radiator, so directly calculating the heat sum. Its advantages are object result, high efficiency, simple structure and low cost.

Description

A kind of integral calibrating table for calorimeter
The present invention relates to heat metering equipment, particularly relate to the used integral calibrating table for calorimeter of heat metering.
Meterage has become a hot issue in the heat supply, and its win or lose has become the root problem that is related to the heat supply undertaking survival and development.Just begin starting at China's heat metering, generally all adopted the heat metering instrument to calculate heat separately.And adopt the heat metering instrument to calculate heat, and then should the heat metering instrument be demarcated, just can obtain measuring more accurately effect.For one family consumption, the expense of consumption of calorie is also more than the summation of the electricity charge, water rate and gas charge in 1 year, and thus, relative more expensive heat with power and water, high-precision heat are demarcated and just seemed particularly important.Ready-made calorimeter caliberating device is not also arranged at home at present.The demarcation mode of calorimeter is all used the method for separately demarcating at present abroad.For example the international metering standard R75 and the European Economic Community formulate the method that all adopts split to demarcate in the standard of standard 1434.The thermometer, flowmeter and the integraph that are about to calorimeter are separately demarcated, and make various piece meet corresponding grade, table look-up by form and judge the grade of calorimeter.The shortcoming that this calorimeter is separately demarcated is that not only calibration result is not directly perceived, the demarcation cycle is long, and apparatus expensive.
In order to overcome shortcoming of the prior art, the purpose of this invention is to provide a kind of integral calibrating table for calorimeter cheaply, the visual result that it can make hotlist demarcate is credible, directly obtains the hotlist precision.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes in the following way: a kind of integral calibrating table for calorimeter, it comprises water storage box, water pump, heat abstractor, flowmeter, heat tracing water tank and calorimeter to be calibrated.Its design feature is: be equipped with electric heater and a plurality of thermometer of measuring distribution of water temperature in the water tank in the described heat tracing water tank.The heat tracing water tank is serially connected with electric energy meter outward.The water storage box water inlet is connected with tap water, and the water storage box water delivering orifice is connected with the water delivering orifice of water pump water inlet, heat abstractor, and pump outlet is connected with calorimeter to be calibrated water inlet inlet and is equipped with flowmeter between it.Calorimeter water inlet outlet to be calibrated is connected with heat tracing water tank water inlet, and calorimeter to be calibrated goes out water inlet and is connected with the heat tracing water outlet of water tank, and calorimeter to be calibrated goes out water out and is connected with the heating radiator water inlet.
According to above-mentioned technical scheme, described thermometer adopts platinum-resistance thermometer; Described flowmeter adopts suspended body flowmeter.
For the ease of various operations of regulating system and declared working condition, according to technique scheme, between described heating radiator water inlet and its water delivering orifice, between calorimeter to be calibrated water inlet inlet and the flowmeter water delivering orifice, pump outlet and flowmeter water inlet junction be equipped with stop valve.
Owing to the heat tracing water tank is set in the calibrating table of the present invention and a plurality of thermometers is set therein.Water at low temperature flows into the heat tracing water tank through calorimeter undetermined, flows out through calorimeter undetermined after electric heater is the water heating again.So the heat that obtains by the heat tracing water tank can converse the heat that calorimeter undetermined measures.Its expression formula is: Q=E-Q1-DE, the heat summation of Q-calorimeter metering in the formula; The recruitment of energy in the water in the DE-water tank; E-electric heater heating heat; Heat dissipation capacity between Q1-heat tracing water tank and the heat instrument.This shows by above-mentioned expression formula, can directly obtain the relatively accurate hotlist gauging calibration reading of calibration result and precision.The demarcation efficient of using this calibrating table to recognize to improve calorimeter greatly no longer needs to consume a large amount of time calorimeter is taken apart, identifies respectively.Compare with prior art, have the advantages that design concept is reasonable, simple in structure, cost is low, work efficiency is high.
The present invention will be further described below in conjunction with accompanying drawing and concrete embodiment.
Accompanying drawing is a structural principle connection layout of the present invention.
Referring to accompanying drawing, calibrating table of the present invention comprises water storage box 3, water pump 1, heating radiator 2, suspended body flowmeter 10, heat tracing water tank 6 and calorimeter to be calibrated 4.Be equipped with electric heater 8 and a plurality of platinum-resistance thermometer 5 of measuring distribution of water temperature in the water tank in the heat tracing water tank 6.Electric heater 8 can use ceramic electrical hot pin, electrothermal tube or resistance wire.The heat tracing water tank 6 outer electric energy meters 7 that are serially connected with.Water storage box 3 water inlets are connected with tap water, and water storage box 3 water delivering orifices are connected with water pump 1 water inlet, heat abstractor 2 water delivering orifices.Water pump 1 water delivering orifice is connected with calorimeter to be calibrated 4 water inlet inlets and is equipped with flowmeter 10 between it.Calorimeter 4 to be calibrated goes out water out and is connected with heat abstractor 2 water inlets.Between heat abstractor 2 water inlets and its water delivering orifice, between calorimeter to be calibrated 4 water inlet inlet and flowmeter 10 water delivering orifices, water pump 1 water delivering orifice and flowmeter 10 water inlet junctions are equipped with stop valve 9.Pipeline between heat tracing water tank 6 and the coupled calorimeter to be calibrated 4 is provided with strict heat-insulation layer, reduces leaking heat as far as possible.When using calibrating table of the present invention, each interface of calorimeter 4 to be calibrated is connected with above-mentioned the corresponding interface position.Make water cycle by water pump 1, by flowmeter 10 detect discharges and by the temperature difference before and after a plurality of thermometers 5 experiments get in the water tank in the water can recruitment, draw electric heater 8 heating heat by electric energy meter 7, leak hot experimental result according to water tank again and determine that leaks a hot coefficient, simultaneously with reference to environment temperature and water temperature as the heat dissipation capacity between heating water tank and the calorimeter to be calibrated.Can draw the heat summation of calorimeter metering.When in various operating modes, regulating, open each stop valve 9 or regulate water pump and blower fan in set frequency converter realize.
