Background technology
Along with China's rapid economy development, people's living standard is also constantly improving, and the comfortableness of current building and heating mode causes people's attention gradually, and people have recognized that the thermal comfort type is to people's psychology, the significant impact of physiological health simultaneously.Low-temperature radiant floor heating system is applied in the modern construction engineering as a kind of energy-efficient, easy to use, Heat stability is good, novel heating system that human sense of comfort is strong just increasingly extensively.The floor panel heating mode is different from traditional heating system, is to be hot face with whole floor because of it, and the floor is with the form release heat of radiation and convection current, and has enlarged indoor heating surface area, has increased efficiency of energy utilization.Particularly current China is promoting the use of household metering system, and low-temperature radiant floor heating system more is subjected to people's favor.But the thing followed is buried the behaviour in service that coil pipe safe operation problem in ground will directly affect the building user.Because installing when burying the ground coil pipe to make it produce defective, and along with burying the increase of working time of ground coil pipe, burying ground, coil pipe is more perishable leaks, this can bring potential safety hazard to the indoor heating operation, and the normal operation that defective is buried the ground coil pipe with influence destroys indoor environment and building user's normal life, work.Therefore, before central heating, detect the housing floor radiant heating apace and bury whether defectiveness of ground coil pipe, have crucial meaning.But in the prior art, also do not have a kind of device simple, easy to use to finish the device that the domain defective tube carries out fast detecting is buried in heating.
Summary of the invention
The technical matters that proposes in order to solve in the background technology, the utility model provides a kind of floor panel heating to bury domain defective tube sniffer, this device can be before central heating, detect apace the housing floor radiant heating bury ground coil pipe whether have defective, after detecting, can determine defective locations, can detect together in a plurality of rooms simultaneously with the infrared imaging instrument, improve operating efficiency, reduce maintenance cost.
The technical solution of the utility model is: this kind floor panel heating buries domain defective tube sniffer, comprises PC, attemperating unit, PLC module, air pump, air intake opening numeral pressure transducer, gas outlet numeral pressure transducer, air intake opening digital flow sensor, gas outlet digital flow sensor and some connection flexible pipes.Wherein, described connection flexible pipe as with the link of the water trap in house, described attemperating unit is provided with the heating chamber that is used to add hot fluid, the import of this heating chamber is connected to the connection flexible pipe of water trap endpiece, the outlet of this heating chamber is connected to the fluid intake of air pump, and the fluid egress point of described air pump is connected to the connection flexible pipe of water trap inlet end; Described water inlet numeral pressure transducer and water inlet digital flow sensor are installed on described defect detection device inlet end, described water delivering orifice numeral pressure transducer and water delivering orifice digital flow sensor are installed on described defect detection device endpiece, described PLC module is gathered the signal of sensor as aforementioned output under the control of plug-in, and via telecommunication cable digital signal is sent to described PC.
Adopt this scheme, described connection flexible pipe is connected with the water trap in house, makes to bury ground coil pipe and pick-up unit pipeline formation loop.By attemperating unit the air in the coil pipe is heated, and bury the ground coil pipe in the house by the air transfer of air pump after heating.Described digital pressure transducer and digital flow sensor respectively are installed in sniffer entrance and exit place respectively, to measure the air themperature and the pressure at entrance and exit place.Described PLC module is gathered the sensor as aforementioned signal under the control of plug-in, and digital signal is sent to PC, whether has defective through determining to bury the ground coil pipe after calculating.The sensor as aforementioned signal can be monitored, shows and be stored to described PC simultaneously.
The utlity model has following beneficial effect: the user uses floor panel heating to bury the ground coil pipe when defective occurring, leaks out hot water through regular meeting.There is the temperature difference in the utility model based on the hot water of these leakages and surrounding buildings material and influences the factor in temperature field, floor, by detected temperatures field local temperature this feature that obviously raises, can determine apace that the housing floor radiant heating buries the ground coil pipe and whether has defective, re-use the infrared imaging instrument afterwards and can determine its accurate position.After the application, can improve floor panel heating and bury ground coil pipe safe operation efficient, reduce maintenance cost, strengthen energy utilization rate.That summarizes says, adopt the device described in the utility model can be enough succinct method fast, before the house central heating, detect the housing floor radiant heating and bury the ground coil pipe and whether have defective, afterwards, determine the position of its defective with the infrared imaging instrument.Can in various building structures, detect by this device, for the safe operation of heat supply pipeline is given security, and can reduce the house maintenance cost, improve energy utilization rate, and be easy to fitting operation, have be easy to carry, characteristics that installation cost is low.
