Embodiment Construction

[0046] Reference attached figure 1 , the present invention will be described in detail below.

[0047] The figure shows an intelligent dynamic balance electric control valve with energy metering function, including the electric control valve assembly 2 and the angular stroke analog electric actuator 14 connected with the electric control valve assembly 2, which is used to implement the electric control valve (such as regulating butterfly valve, regulating ball valve) analog adjustment. The front valve body 6, the electric regulating valve assembly 2, and the rear valve body 1 are connected in sequence, and assembled into one body through the connecting bolts 3. The electric regulating valve assembly 2 is an electric regulating butterfly valve assembly, and an electric regulating ball valve assembly can also be selected. The valve body can be a cylindrical body with equal diameter or a variable diameter cylindrical body, and the valve body and the electric regulating valve as...

Abstract

This invention relates to a control method for dynamic balancing electric regulating valve with energy metering function and valve thereof. To This intelligent valve, opening the butterfly valve with an electric actuator to let water flow in from interval channel of front valve to cross the pore plate and butterfly valve and final flow out from the interval channel of the back valve; arranging meters on ends of the pore plate to measure dynamic pressure difference; arranging temperature sensors for valve body and water supply pipe to measure temperature difference and compute energy. This invention has ideal regulation characteristic with simple construction and low cost, and has obvious benefit to comprehensive energy conservation.

Description

technical field [0001] The present invention relates to a valve control method and valve. More specifically, the present invention relates to an intelligent dynamic balance electric regulating valve control method and valve with energy metering function. Background technique [0002] 50% to 65% of the annual energy consumption of high-end buildings is consumed in the central air conditioning system. Compared with the variable flow air conditioning system and the constant flow air conditioning system, the average energy saving of the water pump and cooling tower equipment can be 60% to 80%, and that of the refrigeration host can be saved by 10%. %~40%. However, there is a common phenomenon of hydraulic imbalance in the variable flow water system of air conditioners, and the hydraulic imbalance of the pipe network is likely to cause a lot of waste of system energy and increase of equipment operating noise. The use of intelligent dynamic balance electric regulating valve cont...
