Abstract

The invention discloses an air pressure stable flow self-balancing device, which comprises a casing, an inlet guide assembly, a pressure balance assembly, a support ring and an outlet guide assembly, the inlet guide assembly, the pressure balance assembly, the support ring and the outlet guide assembly The flow components are connected in sequence and installed in the housing. The two ends of the housing are inlet and outlet, which are used to realize docking with the system. The utility model has the advantages of simple structure, low cost, strong stability, convenient operation, no external power source, and can realize automatic balance of system pipeline flow when the system load changes.

Description

technical field [0001] The invention belongs to the field of flow regulating devices, in particular to an air pressure stable flow self-balancing device. Background technique [0002] Changing the resistance of the pipeline system by means of throttling is a common method to control the flow of the pipeline system, and it is also an important means to ensure the stable operation of the pump unit in the pipeline system. When the user or load of the pipeline system changes, there is a certain degree of deviation in the system flow and the flow of each branch. At this time, in order to prevent large flow fluctuations in each branch, it is usually necessary to adjust the system resistance on the branch to control the flow of the system separately to ensure that users The flow is stable. The commonly used method is to automatically control through the automatic flow regulating valve and the flow meter, but there are many components, complex structure and poor reliability. Cont...
