Problems solved by technology
[0003] The purpose of the present invention is to provide a guide body to solve the problem of unstable flow field and liquid flow impact of liquid in the verification device
The guide body of the present invention is arranged at the liquid inlet of the weighing container 5 and the water container 6, the water flow is separated by the tip of the cone and guided into the container along the side wall, so the impact of the liquid flow is greatly weakened, Solved the problems of unstable flow field and liquid flow shock in the test device
[0004] The present invention also provides a calorimeter verification device using the above-mentioned guide body to solve the problems of unstable flow field and liquid flow impact in the verification device

specific Embodiment approach 1
[0007] Embodiment 1: The shape of the guide body in this embodiment is a cone.
specific Embodiment approach 2
[0008] Specific implementation mode two: the following combination Figure 4 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that the guide body is a cone, and the apex angle α of the cone is 10 degrees to 150 degrees. The optimum is 30 to 40 degrees.
specific Embodiment approach 3
[0009] Specific implementation mode three: the following combination Figure 5 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that the guide body is divided into multiple sections from the height direction, forming a stack of the top cone 10 and the multi-section frustum of cone 11, and the cone apex angle of the top cone 10 and the multi-section frustum of cone 11 is from the top It increases successively from bottom to bottom, and the cone apex angle α of the top cone 10 is 30° to 40°. With such arrangement, the profile of the side surface of the guide body forms an approximately concave curve shape, which is beneficial to the buffering of the liquid.

The invention provides a stream guider and a heat meter calibrating installation using the same and relates to a stream guider in the heat meter calibrating installation. The invention also relates to a heat meter calibrating installation using the stream guider. The stream guider is used for calibrating the heat meter and solves the problem of unstable flow field and liquid stream impact in the calibrating installation. One scheme of the calibrating installation is that an input end of a pump is communicated with the inner chamber of a water container, an output end of the pump is communicated with a liquid inlet of a standard heat meter, a liquid outlet of the standard heat meter is communicated with one end of a mounting gauge stand of the heat meter to be calibrated, the other end of the mounting gauge stand of the heat meter to be calibrated is connected with the inner chamber of the water container by a return water pipe, a number 1 stream guider is arranged in the inner chamber of the water container and the top end of the number 1 stream guider is arranged below the return water pipe. The other scheme is that a weighing device is used for calibrating accuracy of the heat meter. In the calibrating installation, the stream guider is used for buffering impact of liquid so as to stabilize the flow field in the calibrating device.
Description
technical field [0001] The invention relates to a guide body used in a heat meter verification device. It also relates to a heat meter verification device using the guide body. Background technique [0002] At present, many northern cities have realized heating network heating in winter. The heat supply of the heating network requires a large number of meters or other metering devices. These heat meters or heat metering devices need to be checked and calibrated frequently in order to achieve accurate metering. Existing heat meter verification and calibration devices such as figure 1 As shown, its working principle is as follows: through the pump 1, the same flow rate flows through the standard heat meter 2 and the detected heat meter 3 in sequence, and the detected heat meter is detected by comparing whether the indication values of the two heat meters are the same 3 is accurate. The weighing device 4 for measuring weight is also utilized to measure whether the value f...
