Energy-saving flow automatic regulator and application method thereof in heat supply network flow regulation

Abstract

The invention relates to an energy-saving flow automatic regulator and an application method thereof in heat supply network flow regulation. The regulator is formed by threading a venturi tube having a flange to a shell, wherein the venturi tube is provided with a pressure meter, a flow meter and a fine tuning device; a rotating pipe is arranged in the venturi tube; a regulating cylinder is sleeved on the venturi tube in the shell; a spring is arranged between the regulating cylinder and the shell; a window is opened on the proper position on the side wall of the rotating pipe, the venturi tube and the regulating cylinder; and a regulating cylinder bottom hole is arranged on the bottom of the regulating cylinder. The energy-saving flow automatic regulator is arranged at an inlet of a heat supply network branch and two ends thereof are provided with a disconnecting valve so as to overhaul, exchange and regulate. When the regulator is used for regulating, the disconnecting valve can be regulated according to the indication of the flow meter in order to accord with the design, therefore simplifying the primary regulation of the system. Through making an industrial standard, the factory and the user can conveniently make and use the regulator. The flow is regulated by decreasing the system resistance, therefore saving energy consumption of a water pump. The quantity and quality are regulated for optimizing the heat flow regulation, therefore saving energy.

Description

Technical field [0001] The invention belongs to a heating network flow control facility and an application method thereof in the heating network. Background technique [0002] "Heating Ventilation and Air Conditioning" magazine 2009.1, page 2 wrote: "(my country) heating network lacks control facilities, heat distribution is uneven, and heat energy loss accounts for 10%-20% of the basic heating heat consumption, resulting in Energy waste". [0003] The root cause of the uneven heat distribution of the heating network is the uneven distribution of the heat medium flow of the heating network. Therefore, what the heating network lacks is the regulation and control facility that can maintain the flow distribution evenly during dynamic operation. [0004] There are two types of existing heating network flow regulating devices, namely manual regulating devices and automatic regulating devices. The former such as orifice plate, regulating valve, etc., the latter such as different...

Problems solved by technology

[0010] (1) The new device should meet the requirement that when the flow rate at the heat source outlet of the system changes, the flow rate at the inlet of each branch line should change at an equal percentage to solve the problems of hydraulic imbalance and uneven heating and cooling;
