Detailed Description
Fig. 1 schematically shows a tube pressure type flameproof valve according to an embodiment of the present invention. The tube pressure type explosion-proof valve comprises a tube pressure valve 2 and an air storage tank 1.
The pipe pressure valve 2 is communicated with the gas storage tank 1 through a pipeline, and a pulse solenoid valve 3 is arranged on the pipeline through which the pipe pressure valve 2 is communicated with the gas storage tank 1. The pulse solenoid valve 3 is used for communicating or cutting off the connection between the air storage tank 1 and the pipe pressure valve 2. The inlet pipeline of the gas storage tank 1 is provided with a first electromagnetic valve 4. Be equipped with check valve 5 on the pipeline of first solenoid valve 4 and gas holder 1 intercommunication, the entry and the 4 intercommunications of first solenoid valve 5, the export and the gas holder 1 intercommunication of check valve 5. The one-way valve 5 is arranged to prevent the gas in the gas storage tank 1 from flowing backwards due to overlarge pressure, so that the gas tightness of the gas storage tank 1 is ensured. The gas storage tank 1 is provided with a pressure sensor 6 for detecting the gas pressure in the gas storage tank 1. The pressure sensor 6 is connected to the first solenoid valve 4. The pressure sensor 6 controls the opening and closing of the first electromagnetic valve 4. When the pressure sensor 6 detects that the pressure in the gas storage tank 1 reaches the required range, a signal is sent to close the first electromagnetic valve 4, and the gas injection into the gas storage tank 1 is stopped. When the pressure sensor 6 detects that the pressure in the gas storage tank 1 does not reach the required range, a signal is sent out to open the first electromagnetic valve 4, and gas starts to be injected into the gas storage tank 1. The gas storage tank 1 is also provided with a pressure gauge 11. The operator can also judge whether the gas in the gas storage tank 1 reaches the specified numerical range according to the data on the pressure gauge 11. And a second electromagnetic valve 8 is arranged on an outlet pipeline of the pipe pressure valve 2. The pulse solenoid valve 3 is connected to a front-end sensor 7 for detecting an explosion signal. The front-end sensor 7 is connected with the second solenoid valve 8 and the pulse solenoid valve 3, respectively. The front-stage sensor 7 is a pressure detection sensor 71 or a spark detection sensor 72 for detecting an explosion signal by pressure, spark, or the like. The pressure detection sensors 71 are connected to the second solenoid valve 8 and the pulse solenoid valve 3, respectively. The spark detection sensor 72 is connected to the second solenoid valve 8 and the pulse solenoid valve 3, respectively. Facilitating the timely detection of an explosion or flame signal. In this embodiment, the pressure detection sensor 71 is selected as the anterior sensor 7.
The tube pressure type explosion-proof valve also comprises a PLC control system. The PLC control system is respectively connected with the first electromagnetic valve 4, the pressure sensor 6, the second electromagnetic valve 8, the pulse electromagnetic valve 3 and the front section sensor 7. The PLC control system controls the on-off of the first electromagnetic valve 4 according to the detection signal of the pressure sensor 6. The PLC control system controls the on and off of the pulse electromagnetic valve 3 and the second electromagnetic valve 8 according to the explosion signal detected by the front sensor 7.
As shown in fig. 2, in normal operation, the tube pressure type flameproof valve is in an open state.
As shown in fig. 3, when an explosion occurs, the front-end sensor 7 detects an explosion signal, and then sends a signal to control the pulse solenoid valve 3 to open and control the second solenoid valve 8 to close, so as to fill the gas in the gas storage tank 1 into the pipe pressure valve 2, and the pipe pressure valve 2 closes to isolate the explosion, prevent a secondary explosion, and protect downstream people and equipment.
In the process, when the pressure sensor 6 detects that the air pressure in the air storage tank 1 is relatively low, a signal is sent to open the first electromagnetic valve 4 to inject air into the air storage tank 1, and when the pressure sensor 6 detects that the air pressure in the air storage tank 1 reaches a required range, a signal is sent to close the first electromagnetic valve 4 to stop injecting air into the air storage tank 1. When the pressure sensor 6 detects that the air pressure in the air storage tank 1 does not reach the required range, a signal is sent out to open the first electromagnetic valve 4, and the air starts to be injected into the air storage tank 1.
In addition, when the system is powered off or restarted or the manual operation is lost, the PLC control system controls the pulse electromagnetic valve 3 to be opened, all gas in the gas storage tank 1 flows into the pipe pressure valve 2, and the pipe pressure valve 2 is closed. After the system recovers power supply, the PLC control system controls the pulse electromagnetic valve 3 to be closed, the second electromagnetic valve 8 is opened, and the pipe pressure valve 2 is opened again.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention.
