Description
Technical field
The utility model relates to heat energy meter checkout gear field, specifically a kind of Portable thermal energy table verifying attachment.
Background technology
Heat energy meter as a kind of with ammeter, measurement instrument that water meter is the same, the whether accurate of it is directly connected to economic interests.In calorimeter use procedure, often occur the situation but not having consumption after user uses, first heat energy meter maintainer generally checks from outward appearance, check whether heat energy meter damages, whether battery has electricity, then from heat energy meter parameter testing, whether numerical value has exception; But sometimes, cannot judge that from outward appearance and parameter whether heat energy meter is normal, heat energy meter can only be removed, send heat energy meter to examine and determine station calibrating, but the cycle be longer, cannot fix a breakdown in time, and easily produce metering dispute.
Utility model content
The purpose of this utility model is to provide a kind of Portable thermal energy table verifying attachment, to solve the problem that prior art heat energy meter detects inconvenience.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Portable thermal energy table verifying attachment, include thermal-insulating body, it is characterized in that: in thermal-insulating body, be provided with airtight water tank, water pump is provided with in water tank, electric heater, pump intake is communicated with in water tank, pump outlet is connected with circulating water pipe, circulating water pipe is communicated to water tank opposite side after passing from water tank side again, circulating water pipe has access to standard thermal table, on circulating water pipe, somewhere is broken as the fracture installed for heat energy meter to be measured, gap two ends are set to pipe joint respectively, also electronic temperature controller is provided with in thermal-insulating body, described electronic temperature controller is connected with heat sensor, and heat sensor is arranged in water tank.
Described Portable thermal energy table verifying attachment, it is characterized in that: in described thermal-insulating body, be also provided with main power source, main switch, pump switch, heater button, transformer, described main power source supplies power to water pump in water tank by pump switch, main power source supplies power to electric heater in water tank by heater button, main power source by transformer-supplied to standard thermal table, access fracture heat energy meter to be measured.
Described Portable thermal energy table verifying attachment, is characterized in that: be also provided with socket for subsequent use in described thermal-insulating body.
By heat energy meter access circulating water pipe incision position to be measured when the utility model uses, connected by circulating water pipe with standard thermal table, error between the calorific value that when flowing through standard thermal table, heat energy meter to be measured by calculating hot water, two heat energy meters record, judges that whether heat energy meter to be measured is normal.The utility model is easy to use, and can treating and survey heat energy meter and detect in scene, is that a kind of heat energy meter reliably detects judgment means.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Shown in Figure 1, Portable thermal energy table verifying attachment, include thermal-insulating body 1, airtight water tank 2 is provided with in thermal-insulating body 1, water pump 3 is provided with in water tank 2, electric heater 4, water pump 3 water inlet is communicated with in water tank, water pump 3 delivery port is connected with circulating water pipe 5, circulating water pipe 5 is communicated to water tank 2 opposite side after passing from water tank 2 side again, circulating water pipe 5 has access to standard thermal table 6, on circulating water pipe 5, somewhere is broken as the fracture for heat energy meter installation 7 to be measured, gap two ends are set to pipe joint respectively, electronic temperature controller 8 is also provided with in thermal-insulating body 1, electronic temperature controller 8 is connected with heat sensor 9, and heat sensor 9 is arranged in water tank 2.
Main power source 10, main switch 11, pump switch 12, heater button 13, transformer 14 is also provided with in thermal-insulating body 1, main power source 10 supplies power to water pump 3 in water tank 2 by pump switch 11, main power source 10 supplies power to electric heater 4 in water tank 2 by heater button 13, and main power source 10 supplies power to the heat energy meter to be measured 7 of standard thermal table 6, access fracture by transformer 14.
Socket 15 for subsequent use is also provided with in thermal-insulating body 1.
Operation principle is: the heat energy meter of an assay approval is as standard thermal table, and with heat energy meter to be measured under this device, the same temperature difference, flows through the water of same volume, obtains calorific value Q respectively
ciand Q
di, pass through
calculate relative error Ei.
When Ei≤± 8%, tentatively can judge user not in use, or seldom use, heat energy meter is normal; When Ei > ± 8%, tentatively can judge that heat energy meter error is comparatively large, need to send heat energy meter to examine and determine station calibrating, or heat energy meter is keeped in repair, change.
