Problems solved by technology

[0002] In the prior art, manual control is generally used for the control of the heating network system in the factory. Due to the need to control the outlet temperature of the heater in the heating network system, the amount of control is relatively large. In the whole process, due to the untimely adjustment of personnel, the ambient temperature of the equipment on site Low, causing equipment abnormalities, and there is also a further increase in system energy consumption due to the temperature not being adjusted in time

Embodiment 1

[0033] like figure 1 As shown, a control method applied to the steam inlet valve of the heating network system described in the embodiment of the present invention includes the drain temperature, the ambient temperature and the set temperature value, the drain temperature is the outlet water temperature of the heater 3, The ambient temperature is the temperature at the inlet of the blower, and the set temperature value is the sum of the drain temperature and the ambient temperature after the heating network system runs stably; detect the drain temperature and the ambient temperature, and calculate the sum of the drain temperature and the ambient temperature And, adjust the deviation between the sum and the set temperature value to control the opening of the steam inlet valve 2, and adjust the amount of steam entering the heater 3 to change the outlet water temperature of the heater 3.

[0034] In this embodiment, it includes detecting the actual hydrophobic temperature t1 and ...

Embodiment 2

[0041] like figure 2 and image 3 As shown in the embodiment of the present invention, a steam inlet valve 2 applied to a heat network system, the heat network system includes a blower (not shown in the figure), a boiler (not shown in the figure), a steam turbine 1 , the steam inlet valve 2 and the heater 3, the blower sends the extracted air to the boiler, the boiler is connected to the steam turbine 1, the steam turbine 1 is connected to the steam inlet valve 2, and the steam outlet of the steam inlet valve 2 is connected to the heater The steam inlets of 3 are connected, and the control system sends instructions to the steam inlet valve 2 according to the obtained ambient temperature, and the steam inlet valve 2 adjusts the opening after receiving the instruction to control the amount of steam entering the heater.

[0042] In this embodiment, the steam enters into the heater 3 through the steam inlet valve 2, the ambient temperature is the temperature at the inlet of the ...

Abstract

The invention discloses a controlling method of a steam admission control valve applied to a heating network system. The heating network system comprises a heater and an air feeder. The controlling method involves a hydrophobic temperature, an environment temperature and a given temperature value; the hydrophobic temperature is a water outlet temperature of the heater; the environment temperatureis a temperature of an inlet of the air feeder; and the given temperature value is the sum of the hydrophobic temperature and the environment temperature after the heating network system operates steadily. The hydrophobic temperature and the environment temperature are detected, the sum of the hydrophobic temperature and the environment temperature is calculated, the deviation between the sum andthe given temperature value is adjusted to control the opening of the steam admission control valve, and steam admission amount entering the heater is adjusted to change the water outlet temperature of the heater. According to the steam admission control valve, automatic correction is conducted based on external disturbance of the environment temperature and internal disturbance caused by change of steam amount, and automatic control of heating temperature is realized.

Description

technical field [0001] The invention belongs to the field of heating networks, and in particular relates to a method for controlling an inlet steam regulating valve applied to a heating network system, and particularly relates to a steam inlet regulating valve applied to a heating network system. Background technique [0002] In the prior art, manual control is generally used for the control of the heating network system in the factory. Due to the need to control the outlet temperature of the heater in the heating network system, the amount of control is relatively large. In the whole process, due to the untimely adjustment of personnel, the ambient temperature of the on-site equipment will If the temperature is low, it will cause abnormality of the equipment, and there will also be a further increase in system energy consumption due to the temperature not being adjusted in time. [0003] In view of this, the present invention is proposed. Contents of the invention [000...
