Constant temperature water tank for calorimeter calibrating device

Abstract

The invention discloses a constant temperature water tank for a calorimeter calibrating device. The constant temperature water tank for the calorimeter calibrating device comprises a tank body and further comprises a first water blocking partition plate and a second water blocking partition plate, wherein a plurality of flushing openings are formed in the first water blocking partition plate and the second water blocking partition plate respectively in a dense distribution mode, the first water blocking partition plate is erected on the left side of a hollow chamber of the tank body, the second water blocking partition plate is erected on an electric heating element, the first water blocking partition plate and the second water blocking partition plate are oppositely arranged and mutually staggered, and a winding liquid advancing route is formed by the first water blocking partition plate and the second water blocking partition plate in the tank body. The constant temperature water tank for the calorimeter calibrating device has the advantages that the first water blocking partition plate and the second water blocking partition plate are used for blocking backwater which flows into the tank body so that the backwater can flow to a hot water outlet along the winding liquid advancing route instead of directly flowing to the hot water outlet, as a result, the situation that the backwater directly flows to the hot water outlet without being heated by the electric heating element after a calorimeter is calibrated is effectively prevented, the outlet water temperature at the hot water outlet is ensured, and the detection of the calorimeter can be accurate.

Description

technical field [0001] The invention relates to an accessory of a heat meter verification device, in particular to a constant temperature water tank of the heat meter verification device. Background technique [0002] The heat meter verification device can perform flow sensor, paired temperature sensor, calculator component verification and heat meter total verification for various heat meters; its working principle is: heating the constant temperature water tank to make the water temperature in it reach the set temperature value, start the frequency conversion water pump to send hot water into the test pipeline, flow through the standard flow meter and the heat meter to be tested, and return to the constant temperature water tank; at this time, adjust the flow rate to the set value by adjusting the flow regulating valve and the speed of the frequency conversion water pump At the flow point, put the standard thermometer and the temperature sensor of the tested meter in two c...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a constant temperature water tank for a heat meter verification device to solve the problem that in the prior art, when the return water flow rate of the back water after the heat meter verification is large, the water flow movement in the box will be disturbed, and the water outlet of the water outlet of the box body will be disturbed. The temperature is not constant, which makes the detection of the heat meter inaccurate
