Abstract
Description
Technical Field

[0002] The current GB / T 23137-2020 provides a schematic diagram of the mixing system. When building the mixing system, there are several defects in the process of using it in the laboratory. Figure 1 It can be seen that the existing mixing device lacks a pressure relief valve. When the water pressure is too high at the beginning of mixing, it will damage the pump body, pipeline, etc. of the water pump; it lacks a water replenishing device, making it inconvenient to replenish water before testing; the flowmeter is not actually required for testing and will cause the pipeline to be too long and the cost to be too high; the lower pipeline of the mixing device is too short, and when facing the water inlet of the high-position water tank, the mixing device cannot be installed smoothly; it lacks a drainage device, and the low-temperature water in the initial mixing will accumulate in the pipeline, and it is too time-consuming and laborious to disassemble the device for drainage.
