Background technology
Calorimeter calculates the instrument of heat to be widely used in the measurement instrument that every field belongs to state compulsion calibrating.Flow sensor, pairing temperature sensor, the component detection of counter and the total amount calibrating of calorimeter can be carried out to various calorimeter for the coherent detection department of the calibrating testing of calorimeter and the heat meter calibrating apparatus that needs of manufacturing enterprise, its principle of work is: the rotating speed now passing through adjust flux variable valve and variable frequency pump, uninterrupted is adjusted on set flow point, standard thermometer is placed in together with the temperature sensor of tested table two constant temperature water tanks (simulation entrance and exit temperature) respectively, calibrating is started after system run all right, computing machine gathers associated flow in verification process, the signals such as temperature, calibrating is stopped after running a period of time, automatically the standard amount value during calculating calibrating according to associated hot force equation by computing machine, calculating is compared by the heat indicating value of standard amount value and tested table, realize the verification test to tested table.
Existing for heat meter calibrating apparatus constant temperature water tank, its structure generally comprises casing, this casing is by upper, under, left, right plate, the hollow containment housing that lower shoe and upper plate surround, the electrical heating elements being in this bottom half is provided with in this casing, and by electrical heating elements, cold water is heated, conducting water delivering orifice after design temperature is reached until the water temperature of water in casing, hot water now in casing can from water delivering orifice outflow and through conveyance conduit to tested calorimeter, backwater after calibrating again through return line flow in casing, again heated by heating element, flow out from water delivering orifice again after heating, circulation like this.Constant temperature water tank is the storage water of heat meter calibrating apparatus and the container that heats water.
But, the constant temperature water tank of this kind of structure, there is a fatal shortcoming, exactly electric heater break down need to carry out repair and replacement time, the hot water stored in water tank all must be released, because most of user can not have buffer tank, can only hot water be arranged into sewer, do not only wasting water resource like this, and waste electric energy, for 20 cubic metres of water tank room temperatures 20 DEG C, the electric energy often discharging a water waste is; 694 degree.And draining and add water and heat and approximately need the time, and the time changing electric heater only needs 30 minutes to one hour.
Summary of the invention
The object of the present invention is to provide a kind of heat meter calibrating apparatus heat exchange constant temperature water tank, this heat exchange constant temperature water tank is when breaking down at electric heater, can when main box need to discharge water, just electric heater can be changed with heat exchange valve as long as switch off the pump, time saving and energy saving, alleviate labour intensity, increase work efficiency, economize on resources.
The present invention solves the technical scheme that its technical matters takes: heat meter calibrating apparatus heat exchange constant temperature water tank, its structure comprises main water box and heat exchange box, be provided with electric heater in described heat exchange box, described main water box is connected with the second heat exchange pipeline by the first heat exchange pipeline with heat exchange box;
One end of the first described heat exchange pipeline is connected with the first water delivering orifice of main water box lower sides, the other end of the first described heat exchange pipeline is connected with the first water inlet of heat exchange box sidewall, and the first described heat exchange pipeline is provided with heat exchange water pump and the first heat exchange valve; One end of the second described heat exchange pipeline is connected with the second water delivering orifice of heat exchange box roof, the other end of the second described heat exchange pipeline extends to main water box box house through after the second water inlet of main water box sidewall, and the second described heat exchange pipeline is provided with the second heat exchange valve.
Further, described heat exchange water pump is the heat-resisting water pump of band lining, and the first described heat exchange valve and the second heat exchange valve are stainless steel ball valve.
Further, the first described heat exchange pipeline and the material of the second heat exchange pipeline are stainless steel, and in pipeline, flow velocity is no more than 3m/s, and the volume of heat exchange casing is approximately 1/30 ~ 1/50 of main water box.
The invention has the beneficial effects as follows: the electric heater of this heat exchange constant temperature water tank is not directly installed in main water box, and be mounted in heat exchange box body, when electric heater breaks down, can when main box need to discharge water, as long as closedown heat exchange water pump and heat exchange valve just can be changed or electric heater for maintaining, time saving and energy saving, can also electric resources of wasting water be avoided.
