Abstract
The utility model provides a pneumatic control device, which can automatically conduct power adjusting on a heating apparatus without power supply, and comprises a temperature controller, a mother fire protector, a standby valve, a starting valve, a trip valve, a flow valve and a compression gauge. The standby valve, the starting valve, the trip valve and the flow valve are in series connection through pipelines and form a closed loop. A connecting pipe of the standby valve and the starting valve is communicated with a connecting pipe of the trip valve and the flow valve, forming a Theta-shaped loop. A connecting pipe of the starting valve and the trip valve is provided with the compression gauge. Two ends of the flow valve are communicated through a pipeline. Two ends of the connecting pipe of the starting valve and the trip valve are in parallel connection with the temperature controller through a pipeline, and the parallel pipeline is provided with a dewatering plug. Two ends of the connecting pipe of the standby valve and the starting valve are in parallel connection with the mother fire protector through the pipeline, and the parallel pipeline is also provided with a dewatering plug. The pneumatic control device is advantageous in that automatic adjusting can be conducted on the power of the heating apparatus without electricity, and thereby the purpose of automatically adjusting combustion state can be realized.
Description
Technical field
The present invention is a kind of control gear that heating plant is carried out power adjustments, particularly a kind of air control unit that does not need power supply just can automatically carry out power adjustments to heating plant.
Background technique
In oilfield surface engineering, Oil/gas Well product storage and pipeline are carried or the needs of other mode of movements in order to satisfy, the oil field shaft mouth product must be heated, in heating process, must regulate the power of heating plant, the power adjustments of heating plant all must be controlled by special control gear.The control gear that uses on the oil field at present is necessary electricity consumption all, and under large-area desert, Gobi desert environment, can not satisfy the requirement that realizes energising at the well head of all needs heating fully, so in the situation that do not have electricity, the power adjustments of heating plant just is difficult to carry out.
Summary of the invention
The objective of the invention is in order to overcome existing control gear in the situation that the defective that does not have electricity just can not control the power adjustments of heating plant is invented a kind of air control unit that does not need power supply just can automatically carry out power adjustments to heating plant.
The objective of the invention is to realize by following technological scheme: described air control unit comprises temperature controller, female fiery protector, service valve, starter gate valve, cut-off valve, Flow valve and pressure gauge;
Service valve, starter gate valve, cut-off valve and Flow valve are connected into the closed-loop path by pipeline, and the connecting tube of service valve and starter gate valve is connected with the connecting tube of cut-off valve and Flow valve, its whole loop that consists of one " day " font;
The connecting tube of starter gate valve and cut-off valve is provided with pressure gauge;
Pipeline connection is passed through at the two ends of Flow valve;
The connecting tube two ends of starter gate valve and cut-off valve are in parallel with temperature controller by pipeline, and this parallel pipeline is provided with hydrophobic plug;
The connecting tube two ends of service valve and Flow valve are in parallel with female fiery protector by pipeline, also are provided with hydrophobic plug on this parallel pipeline.
Described service valve, starter gate valve, cut-off valve and Flow valve are located in the control box, and pressure gauge is located at the control box top, and the handle of service valve and starter gate valve is located at the control box top, and hydrophobic plug is located at the control box bottom.
Good effect of the present invention is as follows: the present invention is in the situation that just can automatically adjust to the power of heating plant the automatic purpose of regulating combustion regime of realization without electricity.
Description of drawings
Fig. 1 is structural drawing of the present invention
Among the figure: 1 temperature controller, 2 female fiery protector 3 service valves
4 starter gate valves, 5 cut-off valves, 6 Flow valves
7 pressure gauges, 8 hydrophobic plug 9 control boxs
Embodiment
As shown in Figure 1, described air control unit comprises temperature controller 1, female fiery protector 2, service valve 3, starter gate valve 4, cut-off valve 5, Flow valve 6 and pressure gauge 7;
The connecting tube of starter gate valve 4 and cut-off valve 5 is provided with pressure gauge 7;
Pipeline connection is passed through at the two ends of Flow valve 6;
The connecting tube two ends of starter gate valve 4 and cut-off valve 5 are in parallel with temperature controller 1 by pipeline, and this parallel pipeline is provided with hydrophobic plug 8;
The connecting tube two ends of service valve 3 and Flow valve 6 are in parallel with female fiery protector 4 by pipeline, also are provided with hydrophobic plug 8 on this parallel pipeline.
Described service valve 3, starter gate valve 4, cut-off valve 5 and Flow valve 6 are located in the control box 9, and pressure gauge 7 is located at control box 9 tops, and the handle of service valve 3 and starter gate valve 4 is located at control box 9 tops, and hydrophobic plug 8 is located at control box 9 bottoms.
During use, female fiery protector is opened starter gate valve automatically owing to being heated, and burner namely drops into normal operation; Temperature controller is carried out Temperature Setting; pressure that pressure gauge showing temperature controller feeds back size, the pressure signal of temperature controller feeds back to Flow valve, thus the open degree of control Flow valve or close; realize the conversion of large and small fire; when temperature reaches setting value when above, Flow valve turns down automatically, when the temperature temperature is reduced to setting value when following; Flow valve leaves greatly automatically; when the situation of abnormal, female fiery protector autoshutdown starter gate valve makes burner be in safely shut down condition.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
