Deduces a resistance relation formula for branch constant flow adjusting. Tests the resistance features of existing three-way valves. Analyses their characteristic curves. Thinks that existing three-way adjusting valves can not realize constant flow. The maximum deviation is 27%. The characteristic curves obtained accords with actual conditions.
