Dynamic balance regulating valve

Abstract

The invention discloses a dynamic balance regulating valve, which comprises an upper valve cover, a lower valve body, an upper valve body, a valve driver, a flow regulating unit and a flow balancing unit, wherein the upper valve cover is positioned above the valve; the lower valve body is positioned below the valve; the upper valve body is positioned between the upper valve cover and the lower valve body and is fastened with the upper valve cover and the lower valve body; the flow regulating unit and the flow balancing unit are positioned inside the valve body and are vertically concentric with upper and lower covers; and the flow balancing unit is positioned on the lower part of the flow regulating unit. The dynamic balance regulating valve is characterized in that: the flow regulating unit is close to the fluid inlet of the valve body and is integrated with the upper valve body through a straight-travel regulating structure. Due to the adoption of a unique integrated design, dynamicflow balancing of the valve is integrated with flow regulating and the dynamic balance regulating valve has the characteristics of compact structure, high flow capacity, high control accuracy, wide working pressure difference range, convenience in assembly and maintenance, long service life and low manufacturing cost and can be applied to industries such as central air-conditioning water systems,urban pipe network water systems, petroleum, chemical industry and the like.

Description

technical field [0001] The invention relates to a valve for controlling flow, more specifically, relates to a dynamic balance regulating valve. Background technique [0002] In the variable flow water system of fluid transmission and distribution different-path pipe network, the actual design often only considers the resistance calculation of the most unfavorable loop. The head may be much larger 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. The regulating valves used at the end of the existing fluid transmission and distribution pipeline network generally do not have the function of dynamically balancing the fluid flow through the valve. Once the system pressure fluctuates, the water flow...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic dynamic balance regulating valve has the disadvantages of high price, small working pressure range, low flow control accuracy, and serious vibration and noise, which cannot meet the needs of actual projects.

From the perspective of product structure, these products simply combine the flow balance valve and the regulating valve together. The resistance coefficient of the valve is large, and the structure is also large. The force value required for closing and the electric power of the actuator are both large. Not conducive to practical engineering application
