(2) background technology:
At present, known about the thermal metering method, measure the instantaneous out temperature and the flow of heat supply heating agent, planimeter reaches pre-heat culvert value built in inside by the temperature difference, the flow that advances backwater and calculates instantaneous heat energy, by the continuous store recording energy consumption of the storage device of inside.Also to have at last and subtract each other and the additional device of the function that multiplies each other, so that can add up total at any time; Obtaining the heat of section sometime with integraph.It has solved the measurement problem of heat energy effectively, but it is still inadequate, the instantaneous out temperature of measuring the heat supply heating agent needs two temperature sensors, integraph, planimeter, integraph, planimeter technical sophistication, price is higher, need feed circuit, such heat measuring method, general cost is than higher, operation troubles is many, not too is fit to the existing heating system of China.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of thermal energy metering system, user's out temperature of heat supply heating agent is fixed in combination with constant temperature mixed valve and thermostatic control valve, substitute temperature sensor, integraph, planimeter and the feed circuit of existing power-supply metering system, use expensive with the meterage that solves present heat energy, operation troubles is many, problem difficult in maintenance.
We know that heating agent absorbs the heat Q of (or emitting) from physics, with self the specific heat capacity J of the volume V of heating agent, heating agent and the temperature variation (T of heating agent
2-T
1) be directly proportional, both:
Heat Q=V * J * (T
2-T
1)
We have known and will calculate the heat energy number that the user uses thus, must measure the temperature difference that enters the user and flow out user's heating agent, and it is that consumption owing to the user causes that this a part of temperature reduces (or rising).Under the general condition, the temperature that enters the user and flow out user's heating agent changes in time, as the temperature that enters the user and flow out user's heating agent immobilizes respectively, and it is just only relevant with the volume V of heating agent to select heat Q, know the volume V of heating agent, just know heat by converting.Constant temperature mixed valve and thermostatic control valve combination can be finished the work that heat medium temperature is constant.
Constant temperature mixed valve is two to advance a by-pass valve control that outes, valve built-in temperature sensor unit, and valve carries out work according to the design temperature of temperature sensor unit.Valve fluid infusion mouth is opened when actuating medium (heating agent) temperature is higher than (or being lower than) valve desired temperature, sneaks into low temperature (or high temperature) meson automatically, makes the valve export medium temperature be stabilized in setting value; And when the temperature of actuating medium was not more than (or being not less than) valve desired temperature, valve fluid infusion mouth was closed, and valve is straight-through duty.
The technical scheme that its technical matters that solves the utility model adopts is:
The thermal metering system of the heat supply of a kind of stationary heat medium, reflux temperature is characterized in that: comprise thermal source part and User Part; In the thermal source part: with thermal source, triplet constant temperature operation valve one, constant temperature mixed valve one serial connection, the fluid infusion mouth of constant temperature mixed valve one links to each other with return line by force (forcing) pump, and triplet constant temperature operation valve one links to each other with return line; At User Part: flowrate control valve, flowmeter, heating radiator, thermostatic control valve two and constant temperature mixed valve two serial connections, the fluid infusion mouth of constant temperature mixed valve two is connected between flowmeter and the heating radiator import.By being connected of thermostatic control valve, constant temperature mixed valve, substitute temperature sensor, integraph, planimeter and feed circuit in the existing power-supply metering system.The beneficial effects of the utility model are not have electronic component, do not need battery, strong interference immunity; The installation and maintenance expense is low, and operation troubles is few, is applicable to the heating system of using the inferior quality heating agent.
(4) description of drawings:
