As shown in fig. 1-5, oil gas flow monitor, including oil dispensing device 1, oil gas recovery device 2 and anti-overflow antistatic control ware 32, oil dispensing device's storage tank 11, delivery pump 12, valve 14 and end dress oil filling riser run through 13 and connect, oil gas recovery of oil gas recovery device 2 irritates, oil gas recovery oil filling riser 22, flow switch 23 and anti-overflow probe rod 24 through connection, its characterized in that: a cross arm of the oil gas recovery oil filling riser 22 is provided with a hole and is welded with a flow switch 23 and an anti-overflow probing rod 24 in sequence; still include main control unit 31, the inside main control board 310 that sets up of main control unit, main control board 310 one side sets up time delay relay 311, main control board 310 connects anti-overflow probe rod signal input terminal 312, flow switch signal input terminal 313, opens pump signal terminal 314 and time delay relay signal input terminal 315, anti-overflow probe rod signal input terminal 312, flow switch signal input terminal 313, opens pump signal terminal 314 and time delay relay signal input terminal 315 and stretch out main control unit 31's shell and fix, it is connected with output pump 12 electricity to open pump signal terminal 314, flow switch signal terminal 313 is connected with flow switch 14 electricity, anti-overflow probe rod signal input terminal 312 is connected with anti-overflow probe rod 24 electricity, the electricity is connected for wired connection. The inside anti-overflow probe circuit board 243 that sets up of anti-overflow probe 24, anti-overflow probe circuit board 243 through rubber seat 242 with prism 241 is connected, anti-overflow probe circuit board 243 and prism 241 overcoat connect cylindrical shell and use epoxy to glue and seal 244, epoxy 244 has explosion-proof effect, prism 241 has refraction effect for the glass material, rubber seat 242 is used for the emitting diode and the receiving diode of protection circuit board.
Further, the main controller 31, the flow switch 23 and the spill-proof probe 24 are designed to be explosion-proof. The anti-overflow feeler lever explosion-proof grade that this product adopted is Ex ia IIB T4 Ga, is the safe circuit of essence, and the safety is guaranteed. The device has the advantages that the signal is output in a delayed mode, the adjusting range of the delay relay is wide (0-10 min), the signal output time can be adjusted according to various factors such as the length and the diameter of a pipeline on site, the time of oil gas in a tank reaching a flow switch 23 is matched with the time of delayed output of the delay relay, and the delay relay is suitable for different site requirements. The type of the anti-overflow probe rod is ET-OP-B. The model of the main controller is ET-GLC. The flow switch 23 is an explosion-proof gas flow switch, and the model thereof is ET-FCS. Whether the oil gas recovery pipeline is unblocked or not is judged by monitoring whether the gas flow exists or not through the flow switch 23, real-time monitoring can be realized, and the accuracy is high; the device can monitor all tank cars by only installing one set on the oil distribution platform, and the tank cars do not need to be modified, so that the device is simple and convenient to install and low in installation cost.
The working process is as follows:
a driver swipes a card on a batch loading controller to carry out self-service loading operation, the loading operation is started, an output pump 12 is started and transmits a signal to a main controller 31 of an oil-gas flow monitor, and a time delay relay 311 in the main controller 31 of the oil-gas flow monitor starts timing (timing time is calculated according to the actual conditions of a field, such as the length of a pipeline, the diameter of the pipeline and the like, so that the time of oil gas passing through the installation position of a flow switch is just in the time range of the time relay);
because the bottom is loaded, the tank body of the tank car is completely sealed, the liquid level is lifted from the bottom of the tank to extrude oil gas in the tank, the oil gas in the pipe enters an oil gas recovery oil filling riser 22 through an oil gas recovery valve and an oil gas recovery joint on the tank car under the action of pressure, and finally enters an oil gas recovery tank 21 on site to be subjected to oil gas recovery;
if the oil gas recovery pipeline is unblocked, oil gas passes through a flow switch 23 arranged in an oil gas recovery oil filling riser within a preset time, the flow switch 23 monitors that the oil gas passes through, and normal loading operation is continued;
if the oil gas recovery pipeline is not smooth (the oil gas recovery valve of the tank car is not opened, the oil gas recovery joint is not opened, the oil gas recovery oil filling riser 2 is not inserted into the oil gas recovery joint on the tank car, the valve of the oil gas recovery pipeline on site is not opened and the like), during the time delay of the time delay relay 311, the flow switch 23 does not monitor that the gas flow passes through, the main controller 31 of the oil gas flow monitor considers that the oil gas recovery pipeline is not smooth, the time relay 311 outputs a signal to the anti-overflow and anti-static controller 32, the anti-overflow and anti-static controller 32 outputs a signal to close the valve 14 and close the output pump 12, the loading operation is suspended, the oil gas flow monitor alarms to prompt the site staff to check the reason that the oil gas recovery pipeline is not smooth, and the loading operation is continued.
In the loading operation process, if the inside medium of tank car excessively overflows if appearing, and the inside anti-overflow probe rod of tank car does not in time output overflow signal, then the medium can get into in the oil gas recovery oil filling riser 22 through the oil gas recovery pipeline, the anti-overflow probe rod 24 of adorning in advance on the oil gas recovery oil filling riser 22 at this moment can monitor that there is the medium to overflow, output signal immediately gives the main control unit 31 of oil gas flow monitor, the main control unit 31 of oil gas flow monitor gives the anti-overflow with signal transmission again and prevents electrostatic control unit 32, emergency shut-off valve 14 and close output pump 12, pause the loading operation. The secondary protection function is realized. If equipment trouble, the utility model relates to an oil gas flow monitor can cut off this equipment and on-the-spot signal of preventing overflow and preventing electrostatic controller, does not influence the on-the-spot normal oil of sending out.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and those skilled in the art can make many variations and modifications of the present invention without departing from the scope of the present invention by using the method and contents disclosed above.
