Abstract
A controllable measuring device used for a heat supply system includes a meter and a first temperature sensor which are arranged at the upstream direction of a heat exchange system as well as a second temperature sensor which is arranged at the downstream direction of the heat exchange system. The controllable measuring device is characterized in that a control device which performs control when the meter is in an abnormal state is arranged at the upstream direction of the meter. The utility model further relates to a heat supply system with the above controllable measuring device.
Description
Technical field
The utility model relates to a kind of measurement mechanism, specifically, relates to a kind of controlled measurement mechanism for heating system, also relates to a kind of heating system that contains described measurement mechanism.
Background technology
Known calorimeter is the instrument of measuring, calculate heat, can measure by hot water flow and water inlet pipe temperature, return pipe temperature.By specific formulation, calculate the heat that heat-exchange system obtains.
In file CN200510015757.9, disclosed a kind of civil heat meter, comprise meter body, be installed in the temperature sensor of heating radiator water supply line and water return pipeline and the flow sensor that constitutes at the signal pickup assembly that water meter arranges, temperature sensor is fixed on the inwall of pipe fitting, the electric wire that connects temperature sensor passes the outer wall of pipe fitting from inside to outside, the signal pickup assembly of flow sensor is installed in the watchcase of water meter sealing, pass watermeter shell from inside to outside with the signal pickup assembly wire connecting, binding post is arranged in the meter body, meter case near binding post is openable, leaves wire hole on the shell.This document quotes in full here as a reference.
The utility model content
Yet in actual use, following faults often appear:
1, the temperature sensor error of pairing use increases, and the illusion that inflow temperature is lower than return water temperature occurs, and last heat is zero or negative value.
2, one or two temperature sensors damage, and short circuit occurs or open circuit, and result of calculation is zero or maximum value.
3, owing to accumulate Shui Xiu incrustation scale in the pipeline, line clogging appears.
The problems referred to above occur, all may cause the rights and interests infringement to house owner, heating enterprise, cause both sides' dispute.If in time pinpoint the problems, take the necessary technology measure, prevent that the negative effect of fault behavior from continuing to enlarge, and show by necessary alarm signal, cause the attention of owner or heating enterprise.
Therefore, must take measures to address the above problem.In conventional calorimeter structural design, increase corresponding hardware and software feature.
1, calorimeter increases the by-pass valve control function, can control the switching of water inlet pipe according to control signal automatically.
2, in the software of calorimeter chip, increase following content:
As occur into coolant-temperature gage be lower than leaving water temperature, measuring circuit short circuit appears or open circuit, result of calculation is zero or maximum value
Discharge stops to count then output valve cut-off signals, stop supplies hot water, and startup sound, light are reported to the police simultaneously.
For the utility model people that deals with problems proposes following technical scheme,
A kind of controlled measurement mechanism for heating system, second temperature sensor that is included in the gauging table installed the heat-exchange system upstream and first temperature sensor and installs in the heat-exchange system downstream, it is characterized in that, be provided with the control device of when gauging table is unusual, controlling in described gauging table upstream.
Best, described control device is a kind of warning system.
Best, described control device is operation valve.
Best, described control device is a kind of sounding and/or luminous device.
Be better than most, described control device is activated by the actuating device that links to each other with gauging table.
A kind of heating system is characterized in that comprising described controlled measurement mechanism for heating system.
Description of drawings
Fig. 1 is device schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, controlled measurement mechanism for heating system of the present utility model comprises the operation valve 3 that links to each other with water inlet pipe 1, in operation valve 3 upstreams manually-operated gate is installed selectively, described operation valve 3 downstreams connect calorimeter or are called gauging table 4, this gauging table 4 is connected with first temperature sensor 5, hot water enters the heating radiator (not shown) via pipeline then, be also referred to as heat-exchanger rig, in described heating radiator downstream second temperature sensor 6 is set, the heat of hot water through behind the heating radiator by heat exchange, entered return pipe 2 by the water after the heat exchange, described second temperature sensor 6 just is installed on this return pipe 2.
As shown in Figure 1, this control device 3 is carried out the operation of setting according to the reading of gauging table 4, just as known to the skilled person, this control device 3 can sound the alarm and/or the alarm light signal, and this control device 3 can also be for cutting off hot water continue the to flow through operation valve of described gauging table 4.
The work of device of the present utility model is as follows:
Hot water is fed to the heating system of the present utility model from thermal source, through the water inlet pipe hand stop valve of flowing through, enters into operation valve, enter into gauging table 4 then, enter heating radiator through piping, hot water comes out to enter into return pipe from heating radiator, is provided with second temperature sensor in return pipe 2., the processor in the temperature difference that first temperature sensor 5 and second temperature sensor 6 are surveyed and other strat test metering devices obtains desired data thereby handling.Described data exception comprises following situation: inflow temperature is lower than return water temperature, and heat is zero or is negative; No flow etc.
Processor in described gauging table can be solidified with operational module, comprises the abnormal data storehouse, comparison module and execution module.
Foregoing description is only used for illustrating the utility model rather than is used for limiting protection domain of the present utility model.Those skilled in the art draw multiple improvement and distortion easily from above-mentioned instruction, only otherwise exceed the protection domain of claim.
