In hot water heating system, because of the influence of design, operation and management and other factors, often circulating flow, system differential pressure, system resistance and system balance etc, and the system imbalance, namely the system hydraulic imbalance is the primary problem of heating effect is poor.Effective means of regulating hydraulic imbalance conditioning equipment installed in the entrance of heat users, generally have a "self operated flow control valve", "self operated pressure control valve". In return the thermal entrance each user network monomer tube mounted on a "self operated flow control valve", of course, depending on site conditions can also be installed in the water supply pipeline, such as because water pressure is too high, not enough pressure radiator or backwater pipeline position tension. Its role is, that each heating monomers according to the amount of hot water heat supply heating area of need.In order to solve this problem, we choose Botou Tongli environmental protection equipment company operated flow control valve as the flow of the heating system regulation and control equipment.Self operated flow control valve is based on the principle of using the constant flow, differential pressure as the driving force, through the linkage of the diaphragm and automatic device of self adjusting function, to achieve the purpose of flow control and stability. In addition to the root system hydraulic disorder, make the heating tends to be more reasonable, the basic realization of the "hot as the use, distribution according to need". Due to the reduction of the proximal source user flow and resistance, so that remote users with differential pressure, circulation is improved, reducing power consumption, coal consumption."Self operated flow control valve" is the principle of orifice plate principle, structure is a combination of porous plate. By manual and automatic two parts, which rely on the pipe itself differential pressure as the driving force, the manual part of the setting flow value, with automatic change with the heat supply pipeline pressure automatic adjustment to do that to make the manual part setting flow value constant.Self operated flow control valve, compared with the manual control valve, balance valve, it has the advantage of a dynamic adjustment function; relative to the electric control valve, it has the advantages of no need of external power, only by the differential pressure of the controlled medium itself as the power, thus saving energy, so it is widely used in heating, refrigeration system.
