The waterway of every water meter is respectively fixed with a temperature measurement sensor. The temperature measurement sensors are respectively an inlet hot water temperature measurement sensor (2) and a runback water temperature measurement sensor (6). An integral arithmetic unit circuit board (7) and an electronic display (10) are fixed in the heat meter. Every water meter is equipped with a hot water flow signal generation collector. The hot water flow signal generation collectors are respectively an inlet signal generation sampler (4) and a backwater signal generation sampler (6). And the signal generation collectors and the temperature measurement sensor are connected by connecting conductors in the casing (9). Calculated results of an integral arithmetic unit are displayed on the electronic display (10).
Description
Technical field:
The utility model belongs to the heat metering instrument, relates in particular to the two-way cummulative metering heat supply of a kind of energy hot water flow to determine whether to dam that hot water and having prevents that temperature probe is split and the bidirectional measuring that the metering that causes is forbidden and the calorimeter of built-in temperature probe with hot family.
Background technology:
At present, the calorimeter that is used for family and other place, great majority all are to adopt a flowmeter that the flow of heat supply hot water is carried out cummulative metering for basic, and the water temperature with import and export draws the heat that the user has used with the temperature probe sampling and after delivering to the enterprising row operation of integrator computing unit again; And temperature probe is often had the mode that exposes line to be connected the import and export of pipeline.This calorimeter will be because of only measuring the heat supply hot water in the inlet chamber, and can not measure the hot water of backflow, thereby can't know whether dammed the user or dammed in the heating process what also have the hot water of heat.The hot water if the user has been dammed in the heating process, one side will increase the amount of boiler end replenishment cycles soft water; On the other hand owing to also having heat to cause the leak of calorimeter metering in the trapped hot water.If the user is installed by-pass line additional between the induction pipe of indoor heating pipeline and recirculatory pipe, and allow a spot of heat supply hot water just flow directly into the backflow temperature probe place of recirculatory pipe without heat exchange, other hot water directly enters sewer after heat exchange, so the calorimeter true used heat of metering user heating at all just.On the other hand, because the line of temperature probe exposes, temperature probe or its line may be removed, thereby cause the measurement of importing and exporting water temperature untruely, also make the truly used heat of metering user heating of calorimeter at last.
The purpose of this utility model provides the calorimeter of a kind of bidirectional measuring and built-in temperature probe, it is the used heat of metering user heating accurately, and can metering heating the dam amount of heat supply hot water of the turnover semi-invariant of hot water and user, it also has the tamper temperature probe and connects the function of lead in addition.
Summary of the invention:
The utility model is achieved in that at one fixes two water meters that can measure hot water by water (flow) direction is minimum on the contrary, each fixing one or more temperature probe on the water route of each water meter in metal or nonmetallic shell.Also be fixed with an integrator computing unit wiring board and an electronic console within it, the signal generation collector that a discharge is all arranged on each water meter, and each signal generation collector all is to connect with being connected lead in the enclosure with the temperature probe and the wiring board of integrator computing unit.Integrator computing unit shows the result of computing on electronic console.
During use, outdoor hot water inlet of the present utility model is connected hermetically with the heat supply inlet pipeline, indoor hot water inlet is connected hermetically with the inlet channel of indoor heating equipment, indoor recirculation water outlet is connected hermetically with the reflux line of indoor heating equipment, and outdoor recirculation water outlet is connected hermetically with the heat supply outlet.When user heating, heat supply pipeline with hot water by outdoor hot water inlet of the present utility model enter the import water meter to its hot water that flows through measure measure with inflow temperature after heating equipment in the inlet chamber again; When through the recirculation water behind the indoor heating equipment, will enter the outlet water meter by indoor recirculation water outlet of the present utility model, and to the recirculation water that it flows through measure with the recirculation water temperature survey after enter the heat supply outlet conduit.After receiving respectively the signal of sending here from import water meter and outlet water meter when integrator computing unit of the present utility model, equate with the recirculation water flow of the present utility model that refluxes out that if enter hot water flow of the present utility model the utility model just carries out heating with the hot water temperature of the hot water flow that flows through the import water meter and import water meter with the difference of the recirculation water temperature of outlet water meter and calculates with heat; If it is unequal with the recirculation water flow of the present utility model that refluxes out to enter hot water flow of the present utility model, then the utility model is used when hot calculating user heating, carry out basic heating calculates with heat except that adopting with the hot water temperature of the hot water flow that flows through the import water meter and import water meter and the difference of the recirculation water temperature of outlet water meter, also to add dammed by the user or the indoor hot water of missing in the heat that comprised.So, even the user has been installed by-pass line additional between indoor induction pipe and recirculatory pipe, and use and make the import hot water temperature identical with the recirculation water temperature and make its no difference than low discharge and without the hot water of heat exchange directly enters the outlet water meter, thereby causing basic heating heat is zero, but at this moment the utility model can be used hot as user's heating the heat that is comprised in the hot water that is dammed by the user and drain.So just avoided present calorimeter because only carry out one-way flow metering, the loss that the heating that causes suffers heat supply unit with the untrue metering of heat.On the other hand, because the lead that is connected of all signal generation sampling thiefs and temperature probe all is in the shell and is sealed, just can't not remove any one temperature probe with signal generation sampling thief and be connected lead if do not destroy this shell, so can not influence measuring accuracy of the present utility model because of these parts partly are removed.
Owing to adopt such scheme, the utility model is the heat used of the heating of metering user accurately, can also cummulative metering enter user's heat supply hot water and leave user's recirculation water, and the dam amount of heat supply hot water of user.And, also have the tamper temperature probe with and be connected the function of lead.
