Abstract
The utility model relates to the technical field of calorimeter detecting systems, and particularly a detecting and weighing device of a calorimeter. The detecting and weighing device includes a work measuring cylinder, an electronic scale, a discharging pipe, a discharging valve, and a circulating water tank, the detecting and weighing device is characterized by further including an overflow pipe, the overflow mouth is arranged in the upper side surface of the work measuring cylinder, the upper port of the overflow pipe is connected with the overflow mouth, and the lower end is communicated with the circulating water tank. When a heat-transfer fluid rises to the upper part of the work measuring cylinder, the residual fluid flows into the circulating water tank via the overflow pipe to prevent the fluid loss due to the overflowing of the fluid., and the mass of the weighed fluid is consistent to that of the fluid of a meter to be detected, so that the meter to be detected meets the detection requirements. The detecting and weighing device provided is advantageous in being reasonable in structure and convenient for operation, and preventing the fluid loss due to the overflowing of the fluid.
Description
Technical field
The utility model relates to the calorimeter testing systems technical field, specifically a kind of heat meter calibration weighing device.
Background technology
At present, the accuracy of standard calorimeter has great impact to the calibration accuracy of system, in order to guarantee the precision of calorimeter testing systems, usually also in circulation line, be provided with the weighing device of tested table, this weighing device comprises the work graduated cylinder, electronic scale, vent pipe, exhaust valve and cyclic water tank, the entrance of work graduated cylinder is connected with circulation line, vent pipe returns to fluid in the cyclic water tank in circulation line by exhaust valve, electronic scale is arranged on the below of work graduated cylinder, in the time need to measuring calibrating to the precision of standard scale, in the heat transport fluid injection work graduated cylinder of certain flow, by electronic scale, it is weighed, and be scaled volume, the volume of resulting bulking value and flow number conversion is carried out to the integral and calculating of volume change, obtain the exchange heat numerical value converted, this exchange heat numerical value compares with the standard exchange heat numerical value that standard scale measurement numerical value calculates again, just can obtain the accuracy of standard scale reading, utilize this weight method, can carry out parameter adjustment to system, the measuring accuracy that keeps this verification system, its deficiency is: when in the work graduated cylinder, injecting heat transport fluid, the staff needs the water filling situation of Real Time Observation work graduated cylinder, slightly do not note, the heat transport fluid of injecting will flow out, cause fluid loss, the quality of fluid of making to weigh is inconsistent with the quality of the tested surface low body of flowing through, cause tested expression less than the calibrating requirement.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to operate, avoid fluid to overflow and cause the heat meter calibration weighing device of fluid loss.
The utility model solves the technical scheme that its technical matters adopts:
A kind of heat meter calibration weighing device, comprise work graduated cylinder, electronic scale, exhaust valve, vent pipe and cyclic water tank, it is characterized in that being provided with run-down pipe, work graduated cylinder upper side is provided with overflow vent, the run-down pipe upper port is connected with overflow vent, lower end is connected with cyclic water tank, when heat transport fluid rises to work graduated cylinder top, unnecessary fluid flows in cyclic water tank through run-down pipe, avoided fluid to overflow and caused fluid loss, the quality of fluid and the uniform quality of the tested surface low body of flowing through make to weigh.
The utility model is owing to adopting said structure, have rational in infrastructure, easy to operate, avoid fluid to overflow and cause the advantage such as fluid loss.
the accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Reference numeral: work graduated cylinder 1, vent pipe 2, cyclic water tank 3, run-down pipe 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of heat meter calibration weighing device, comprise work graduated cylinder 1, electronic scale, exhaust valve, vent pipe 2 and cyclic water tank 3, the entrance of work graduated cylinder 1 is connected with circulation line 3, vent pipe 2 returns to fluid in the cyclic water tank 3 in circulation line by exhaust valve, electronic scale is arranged on the below of work graduated cylinder 1, it is characterized in that being provided with run-down pipe 4, work graduated cylinder 1 upper side is provided with overflow vent, run-down pipe 4 upper port are connected with overflow vent, lower end is connected with cyclic water tank 3, when heat transport fluid rises to work graduated cylinder 1 top, unnecessary fluid flows in cyclic water tank 3 through run-down pipe 4, avoided fluid to overflow and caused fluid loss, the quality of fluid and the uniform quality of the tested surface low body of flowing through make to weigh.
In the time need to measuring calibrating to the precision of standard scale, in the heat transport fluid injection work graduated cylinder 1 of certain flow, unnecessary heat transport fluid flows in cyclic water tank 3 through run-down pipe 4, through cyclic water tank 3, flow in circulation line again, then by electronic scale, the fluid in work graduated cylinder 1 is weighed, and be scaled volume, the volume of resulting bulking value and flow number conversion is carried out to the integral and calculating of volume change, obtain the exchange heat numerical value converted, this exchange heat numerical value compares with the standard exchange heat numerical value that standard scale measurement numerical value calculates again, can obtain the accuracy of standard scale reading, avoided fluid to overflow and caused fluid loss, the quality of fluid of making to weigh reaches consistent with the quality of the tested surface low body of flowing through, be conducive to the calibrating of tested table.
The utility model is owing to adopting said structure, have rational in infrastructure, easy to operate, avoid fluid to overflow and cause the advantage such as fluid loss.
