The invention relates to the technical field of flow control valves, and discloses a dynamic flow balancing valve which comprises a valve body and a valve element assembly. The valve element assemblycomprises a guide sleeve, a limiting sleeve and a valve element which are coaxially arranged. The end of one side of the guide sleeve is provided with a water inlet communicating with the a water inlet end, an adjustable flow hole and a fixed flow hole are sequentially formed in the outer wall of the guide sleeve in the water flowing direction, the end of one side of the limiting sleeve is provided with a water outlet communicating with a water outlet end, the end of the other end of the guide sleeve is fixedly sleeved with the limiting sleeve fixedly connected with the inner wall of the valvebody, the fixed flow hole communicates with the water outlet, the guide sleeve is sleeved with the valve element capable of sliding in a reciprocating mode, the flow area of the adjustable flow holeis changed through sliding of the valve element, and therefore the adjustable flow hole communicates with or is separated from the water outlet. According to the dynamic flow balancing valve, the valve element, the guide sleeve and the limiting sleeve are not likely to be clamped, stability is high, and the adjustable flow hole and the fixed flow hole are small in resistance coefficient and low innoise.
Description
technical field [0001] The invention relates to the technical field of flow control valves, in particular to a dynamic flow balancing valve. Background technique [0002] With the rapid development and progress of valve technology, in order to ensure the stability of the pipeline system, the application of dynamic flow balance valves in ship valve pipeline systems has gradually increased. Dynamic flow balance valves are mainly used to solve the problem of dynamic hydraulic imbalance. [0003] At present, foreign dynamic flow balance valves are generally assembled in an integrated way. This kind of dynamic flow balance valve is not convenient for later inspection, maintenance, and cleaning. After long-term operation, the control accuracy will decrease and energy consumption will increase; The initial working pressure of the valve is generally high, and the flow accuracy is low. The same problem exists in the later inspection, maintenance and cleaning, and the reliability is p...
