Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hydraulic balance adjustment, especially relates to a heat supply pipe network hydraulic balance adjustment device. BACKGROUND

[0002] In the heat supply pipe network, hydraulic balance refers to the actual flow of each user or each branch being equal or close to the design flow, so as to ensure that each user can obtain the heat required by the design. When the hydraulic balance, hot water can be reasonably distributed in the pipe network, avoiding the situation that some users are overheated and some users are overcooled. When the system hydraulic is unbalanced, in order to meet the heat supply demand of the most unfavorable loop (usually the loop farthest from the heat source and the loop with the largest resistance), the circulating water pump often needs to provide greater flow and lift. This will lead to an increase in pump energy consumption. After hydraulic balance adjustment, this energy waste can be avoided, and the operation cost of the heat supply system can be reduced.

[0003] In the utility model with application No. 202122415354.0, a heat supply pipe network water balance adjustment device is disclosed. Water flow is guided into the water storage tank through the water pipe. Due to the large water flow pressure, the movable valve plate moves right along the inner wall of the first adjusting mechanism. The movable valve plate drives the blocking block to move right, so that the flow dividing groove is exposed. The water flow in the first adjusting mechanism enters the flow dividing tank through the flow dividing groove. The water flow is adjusted by the flow dividing tank. When the water flow pressure is small, the electromagnetic valve is opened, so that the water in the water storage tank enters the first adjusting mechanism, which is convenient for dealing with the situation that the water flow pressure is small. The valve flap is driven by the oil cylinder to move downward, which is convenient for changing the water output of the water outlet pipe. The water inflow of the far area is large, while the water inflow of the near area is small, which is convenient for automatically adjusting the hydraulic balance.

[0004] However, the above-mentioned heat supply pipe network water balance adjustment device cannot automatically judge the water pressure and adjust it. When the electromagnetic valve is directly opened to release water, the water flow size will be affected by the water pressure in the water storage tank, and linear adjustment cannot be performed. In the above-mentioned heat supply pipe network water balance adjustment device, the size of the valve flap is fixed and interlocked, so that the water inflow of a specific pipe cannot be adjusted alone. Therefore, the utility model proposes a heat supply pipe network hydraulic balance adjustment device to solve the problems in the prior art. UTILITY MODEL CONTENTS
