Description

The invention relates to heat meters using a thermopile placed by their joints in the forward and reverse pipelines.

In the proposed heat meter, to include in the electrical measuring device circuit of a certain number of thermocouple thermopiles, the slider serves as a slider controlled by a device moving depending on the speed of the heat transfer medium and made in the form of a spring from a flat flat tape placed in the pipeline and connected to the slider or a conical shape with nozzles of the nozzle, also placed in the pipeline and connected by a rod with a slider located inside or outside the pipeline under the action of a spring on the other side.

In FIG. 1 depicts a heat meter circuit; FIG. 2 - the same, with the engine outside the pipeline; FIG. 3 - the same, with a conical nozzle; FIG. 4 is a perspective view of a spring of a moving device.

The heat carrier, for example, hot water, goes through the pipeline / in the direction indicated by the arrow, and cold water goes through the return pipe 2. A thermopile is placed between the pipelines from an electric meter 3 that is sufficient to activate the device.

the number of thermoelements 4, Koiz junctions slightly go into the hot and cold water of both pipelines 1 and 2 and tightly sealed, for which the entire battery, with upper and lower seals, is assembled separately and then inserted into the corresponding sockets of both pipe wires on the screws . A contact slider 5 is placed in the pipeline / moved along the guide b and sliding along the thermocouples 4. The slider 5 is controlled by a device moving depending on the speed of the coolant and made in the form of a spring 7 of a wide flat tape (Fig. 4) , one end fixed rigidly in the pipeline, and the other connected with the slider 5.

When the coolant moves, for example, hot water through pipelines, the spring 7 under pressure of water, depending on the flow rate of the coolant, expands and moves the slider 5, which slides up to the thermoscope thermopile number and includes a different number of thermoelements into the electric meter circuit 3 corresponding to the flow rate of the coolant and its temperature difference in the forward and reverse pipelines.

If the pipelines with great force coolant, for example

the hodoped water, the slider 5 at the same time includes the entire thermopile, but since the water is cold, the thermopile does not give current and - the apparatus 3 does not take into account any heat, but as soon as heat or hot water has gone, the thermopile immediately begins to produce current and the stronger than the water temperature ryshe. But it may be that hot water flows through both pipelines, direct and reverse; it will say that the heat does not evaporate and come back. Since the temperature difference in the pipeline in this case is absent, the thermopile does not give current, and the device, therefore, will not show the flow. At the same heat consumption, due to the temperature difference and the movement of water in the pipelines, the thermopile will react sensitively, transferring a current of greater or lesser force to the instrument for recording. At the same time, the battery discharge at each given moment will characterize the cross energy consumption of heat in aori x. In order to be able to place the valve 5 outside the pipeline (Fig. 2), the latter is supplied with a knee, and the spring 7 placed in the pipeline is connected by a rod 8 passing through the gland to the engine 5 moving along the guide 6, In this case 5 slides not along the thermocouple spacings, but over the contacts connected to the thermocouples located outside the pipeline.

The fixture controlling the slider 5 can be made in the form of a conical, provided with the holes of the nozzle 3 (Fig. 3), placed in the pipe 1 against the flow with a wide end occupying almost the entire diameter of the pipe. Nozzle P is connected by a rod o

with the engine 5, under the influence of the spring 70, the greater the flow rate of the heat transfer fluid, the greater its pressure on the nozzle and the greater its movement.

The subject invention.
