Heat supply system for adjustable jet pumps

Abstract

The invention discloses a heat supply system for adjustable jet pumps. A heat source plant or a boiler, an electric control valve and a primary network circulating pump are connected in series to oneside of a plate heat exchanger to form a primary circulating pipeline; the other side of the plate heat exchanger is connected in series with a secondary circulating pipeline comprising a secondary network circulating pump and heat users; the adjustable jet pumps are additionally arranged before the heat users; jet pump bodies of the adjustable jet pumps are connected in series onto a water supplypipeline; first ball valves and filters are connected onto pipelines at the front ends of the jet pump bodies; second ball valves are connected onto pipelines at the rear ends of the jet pump bodies;water mixing ends of the jet pump bodies are connected with water return pipelines by means of third ball valves; and series connection pipelines on which the first ball valves and the filters whichare connected onto the pipeline at the front ends of the jet pump bodies the jet pump bodies, and the second ball valves connected onto the pipeline at the rear ends of the jet pump bodies are arranged are connected in parallel with balance valves. The heat supply system can well solve the technical problem that a traditional heat supply system is subjected to hydraulic imbalance, and truly realizes heating according to need.

Description

technical field [0001] The invention relates to a regulating system for a heating system. Background technique [0002] At present, the hydraulic imbalance problem of the heating system is a long-standing problem that plagues the heating industry. In a conventional heating system, a balance valve is usually used to solve the hydraulic imbalance of the system, and the balance valve is used alone as the main adjustment means. Due to the coupling and complexity of the heating system itself, when adjusting the opening of the balance valve of individual heat users, other heat users will be affected. To achieve balance, it is necessary to repeatedly adjust the opening of all balance valves in the system, which is difficult to debug Very large, not ideal. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable jet pump heat supply system to better solve the technical problem of hydraulic imbalance in the traditional heat supply system...
