Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a valve opening positioner. Background Art

[0002] In large-scale paper production lines, due to the high degree of automation, a large number of valves are required to achieve automatic control. However, in large-scale paper production lines, the equipment needs to run 24 hours a day, and due to the influence of the on-site environment, the equipment will always fail. The valve is required to restore the normal opening in a short time, and the required opening can be given during maintenance. The existing valves are equipped with mechanical Metso positioners, but when the valve positioner signal disappears, the opening can only be maintained for a short time during the signal generation period, and the opening cannot be maintained for the required time; at the same time, the humid and high temperature environment in large-scale paper production lines affects the life of the equipment, and signal loss and valve cross-gas will also affect the use. When the equipment fails, it is necessary to manually fix the opening with gas, and then disassemble the positioner and find equipment for replacement, which affects the normal use of the valve for a long time; at the same time, when the equipment fails, steam valves and high-altitude valves require maintenance personnel to wait for the valve positioner spare parts for a long time, and frequently manually fix the opening with gas, which cannot control the opening well, and staying in a humid and high-temperature environment for a long time is easy to cause discomfort to maintenance personnel. When the butterfly valve positioner fails, the opening cannot be fixed manually and the valve can only be shut down for maintenance, which affects production use. Utility Model Content

[0067] See also Figure 1-2 This embodiment provides a valve opening positioner, comprising:

[0068] A three-position five-way medium-pressure valve 110, wherein the air inlet 113 of the three-position five-way medium-pressure valve is connected to the valve main air source through an air pipe, the first air outlet 111 of the three-position five-way medium-pressure valve 110 is connected to the valve air inlet source through an air pipe, and the second air outlet 112 of the three-position five-way medium-pressure valve 110 is connected to the valve closing air source;

[0069] A first manual switch valve 120, one end of which is connected to a valve main air source through an air pipe, and the other end of which is connected to a first air control end 114 of the three-position five-way medium-pressure valve 110 through an air pipe;

[0070] The second manual switch valve 130 , one end of the second manual switch valve 130 is connected to the valve main air source through an air pipe, and the other end of the second manual switch valve 130 is connected to the second air control end 115 of the three-position five-way medium-pressure valve 110 through an air pipe.

[0071] When the valve positioner fails and the valve opening cannot be given, it is only necessary to connect the valve opening air source and the valve closing air source to the first air outlet 111 and the second air outlet 112 of the three-position five-way medium-pressure valve 110 of the valve opening positioner through the air pipe, and then connect the air inlet 113 of the three-position five-way medium-pressure valve 110 to the main air source. The three-position five-way medium-pressure valve 110 adopts an air control method, and the first air control end 114 of the three-position five-way medium-pressure valve 110 is connected to the main air source through the first manual switch valve 120, and the second air control end 115 of the three-position five-way medium-pressure valve 110 is connected to the main air source through the second manual switch valve 130. The closing valve 130 controls the main air source to be connected to the first air control end 114 or the second air control end 115 of the three-position five-way medium-pressure valve 110, thereby controlling the required opening of the valve. For example, when the valve scale needs to be increased, the main air source is made to flow to the first air control end 114 of the three-position five-way medium-pressure valve 110 through the first manual switch valve 120, so that the opening air source of the valve is connected to the main air source, and the closing air source is connected to the outside world, so that the valve scale becomes larger. When the valve scale needs to be reduced, the main air source is made to flow to the second air control end 115 of the three-position five-way medium-pressure valve 110 through the second manual switch valve, so that the closing air source of the valve is connected to the main air source, and the opening air source is connected to the outside world, so that the valve scale becomes smaller. When the valve positioner fails, the required valve opening can be guaranteed during the maintenance process. At the same time, when the butterfly valve fails, the valve opening positioner can be used to keep the valve in normal opening until the new positioner is replaced. At the same time, the valve opening positioner is small, compact and light, easy to move and easy to operate.

[0079] A remote controller is communicatively connected with the wireless signal transceiver module of the controller.

[0080] When it is necessary to remotely control the valve to maintain its opening, the first air control end 114 of the three-position five-way medium-pressure valve 110 and the main air source are connected through the first solenoid valve 140, and the second air control end 115 of the three-position five-way medium-pressure valve 110 and the main air source are connected through the second solenoid valve 150. A control signal is sent to the controller through the remote controller to control the operation of the first solenoid valve 140 or the second solenoid valve 150, thereby controlling the valve opening scale. When the valve opening needs to be increased, the first air control end 114 of the three-position five-way medium-pressure valve 110 and the main air source are connected through the first solenoid valve 140, and when the valve opening needs to be reduced, the second air control end 115 of the three-position five-way medium-pressure valve 110 and the main air source are connected through the second solenoid valve 150, so that the valve opening can be remotely controlled. When encountering a high temperature and high altitude environment or needing to deal with other things, maintenance personnel can remotely control the valve opening through the remote controller to maintain production needs.

[0086] Among them, in order to facilitate maintenance personnel to know whether the first solenoid valve 140 or the second solenoid valve 150 is working normally during remote control, a first pressure switch 161 is set on the air pipe between the first solenoid valve 140 and the first air control end 114 of the three-position five-way medium-pressure valve 110, and a second pressure switch 162 is set on the air pipe between the second solenoid valve 150 and the second air control end 115 of the three-position five-way medium-pressure valve 110. When the first solenoid valve 140 is working normally, the controller detects the pressure change through the first pressure switch 161, and controls the first indicator light 171 to light up. When the second solenoid valve 150 is working normally, the controller detects the pressure change through the second pressure switch 162, and controls the second indicator light 172 to light up. When the maintenance personnel are remotely controlling, they can judge whether the first solenoid valve 140 and the second solenoid valve 150 are working normally according to the working conditions of the first indicator light 171 and the second indicator light 172, and further determine whether the valve opening positioner normally maintains the required valve opening.
