FIELD: power engineering. ^ SUBSTANCE: invention may be used in controlling devices of gas supply to gas burners in outside boilers and inside boilers, when device is installed on external supply gas line in front of furnace or boiler house wall. Tank controller comprises body of valve with supply and drain nozzles of external gas line, manometric system with sensitive element, adapter, control spring, stem connected by stop orifice to one end of control spring, threaded bush. Controller is equipped with rotary valve with window of minimum gas supply with positive ambient air temperature, and manometric system with sensitive element via adapter is installed on threaded part of valve body, at the same time rotary valve is made with the possibility of interaction with control disk of manometric system, installed on the second end of stem and separated from threaded bush by means of spacer bush, which provides for automatically controlled supply of gas at low temperatures of ambient air and full supply of gas in case of manometric system failure. ^ EFFECT: simplified design, increased reliability and automatic control of burner devices capacity in case of negative temperatures. ^ 1 dwg |
