Valve liner type adjustable dynamic balance valve

Abstract

The invention provides a valve liner type adjustable dynamic balance valve, wherein the valve liner type adjustable dynamic balance valve utilizes a valve liner type structure, and integrates flow adjusting functions with flow balancing functions so that the whole valve liner components can be assembled out of the valve body, the installation in the valve body can be greatly simplified, the size requirements to the valve body can be reduced, and the repairing of the valve and the replacement of the internal parts are easily performed; the internal structure of the valve is more compact, and the volume and the weight of the valve body can be reduced. The valve liner type adjustable dynamic balance valve further utilizes a helix transmission structure to adjust the flow so that the adjusting precision is high, the torque for adjusting the valve is reduced and the operation is convenient; a flow balancing unit can balance the pressure oscillation of the system so that the flow through the valve is not influenced by the system, and the flow value through the valve is ensured to be completely determined by the opening degree of the valve. According to valve of the invention, the total area of the through flow for the water to pass through is large; larger flow can be obtained; the through flow is even and symmetrical; the resistance coefficient is small and the noise generated by the valve is small.

Description

technical field [0001] The invention relates to a valve, in particular to a valve gall type adjustable dynamic balance valve. Background technique [0002] In the variable flow water system of fluid transmission and distribution, the actual design often only considers the resistance calculation of the most unfavorable loop. When the pressure of the most unfavorable node of the system is guaranteed, the pressure of other nodes may be huge The value is lower than the design value, resulting in hydraulic imbalance of the system. Excessive or improper selection of water pumps will also cause the operating flow to deviate from the design value. The result of hydraulic imbalance in the pipe network is a large waste of energy, increased operating noise and shortened service life of equipment. In order to reduce or eliminate this unbalanced pipe network, the system needs to be continuously debugged, but this adjustment is lagging behind, and the result is that the system is unbalan...
