Embodiment Construction

[0015] Combine below figure 1 The differential heat meter of the present invention is described in detail, figure 1 The double-dot dash line in the middle is the heat meter.

[0016] First of all, it should be noted that the medium in the differential heat meter of the present invention can be any suitable fluid or semi-fluid, but for ease of illustration, water is used as an example below, but the medium used in the present invention is not limited to water.

[0017] like figure 1 As shown in , the differential heat meter of the present invention (hereinafter referred to as the heat meter) includes the water inlet flow distributor 2, the heat counter 4, the return water flow distributor 9 and the connecting pipes between them, the water inlet flow distributor 2 and the The inlet 1 of the heat meter is connected, the outlet of the water inlet flow distributor 2 is connected with the pipeline 3 and the first bypass pipeline 6 respectively, the pipeline 3 is connected with th...

Abstract

The invention relates to a differential type heat meter which comprises an entering water flow divider (2), a heat counter (4), a backwater flow divider (9) and connecting pipelines among the devices, wherein, the entering water flow divider (2) and the backwater flow divider (9) can automatically distribute the flow rate flowing into the heat counter (4) according to medium temperature, and linear relationship is formed between the temperature of the medium and the flow rate flowing into the heat counter (4). The heat meter has the advantages that the structure is simple and heat computation can be realized by totally relying on the medium such as the power of water.

Description

technical field [0001] The present invention relates to a differential heat meter, more specifically to a differential heat meter that relies on the power of a medium (such as water) to measure heat. The invention also relates to a flow distributor, which can be used alone or for a differential heat meter. Background technique [0002] In today's energy-saving society, energy-saving civil heating metering has been raised to the status of national policy encouragement. Existing heat meters are generally completely driven by a power source for heat measurement, with complex structures and large power consumption. [0003] The Chinese patent application with the publication number CN1851425A discloses a passive differential heat meter, which includes an inlet water flow distributor, a heat counter, a return water flow distributor and connecting pipes between them, an inlet water flow distributor and a heat meter. The inlets are connected, and the two outlets of the inflow flo...
