As shown in fig. 7 or 8. The flexible shaft control handle 23 is operated to enable the flexible shaft 24 to stretch out or recover, the flexible shaft 24 drives the rocker arm 20 to rotate, the rocker arm 20 drives the crank 18 to rotate together through the crank shaft 8, the crank 18 drives the recovery valve rod 4 and the recovery valve clack 1 to move up and down together through the recovery valve connecting rod 6, and meanwhile the crank 18 drives the ventilation valve rod 12 and the ventilation valve clack 15 to move up and down together through the ventilation valve connecting rod 16.
The flexible shaft controller is installed at an easy-to-operate position, and the oil gas recovery side plate ventilation integrated valve is remotely controlled through the flexible shaft 24.
The flexible shaft control handle 23 is provided with three gears, which correspond to the three gears of the rocker arm 20, respectively, as shown in fig. 7. The three gears of the rocker arm 20 correspond to three specific working modes of the application respectively. The remote handle support 21 is movably connected with the flexible shaft control handle 23 and is also provided with a sliding groove for the flexible shaft control handle 23 to slide transversely, each gear can be set into a clamping groove, and the flexible shaft control handle 23 is pulled to slide into the clamping groove corresponding to the gear to be clamped, namely, the flexible shaft controller is fixed in the corresponding gear. The flexible shaft controller is the prior art, and does not belong to the protection scope of this application.

Adopt above-mentioned flexible axle controller as external control ware to cooperation crank 18 and last circular spout 25, the operator only needs place flexible axle brake valve lever 23 in corresponding gear, can be with the accurate corresponding concrete operating position of arranging in of vapor recovery valve and sideboard breather valve, perfect and vapor recovery sideboard integrative valve of ventilating is in coordination mutually, thereby realizes the conversion of the three concrete state of this application.
Meanwhile, the oil gas recovery side plate vent valve adopts a manual flexible shaft controller to realize remote interlocking control, and the control problem of an oil gas recovery system of the oil tank truck under the condition of no pressure gas source is solved. Even the oil-carrying and refueling shelter in the shelter without a pressurized air source can be used.
As shown in fig. 1, the exhaust port is provided with a vent valve support 11, and the vent valve stem 12 passes through the vent valve support 11; the oil tank opening is provided with a recovery valve support 3, and a recovery valve rod 4 penetrates through the recovery valve support 3. The vent valve support 11 and the recovery valve support 3 are respectively fixed at the corresponding exhaust port and the oil tank port, so that the vent valve stem 12 and the recovery valve stem 4 do not deviate from the vertical direction when moving up and down, and the straight-up and straight-down movement is realized.
As shown in fig. 1, the oil gas recovery valve further comprises a recovery valve buffer spring 2; the sideplate vent valve further includes a vent valve damper spring 13. The recovery valve buffer spring 2 is used for buffering the connection between the recovery valve clack 1 and the recovery valve rod 4 at a certain position after the recovery valve clack 1 is in a sealing position. The vent valve buffering spring 13 is used for buffering the connection between the vent valve clack 15 and the vent valve rod 12 after the vent valve clack 15 is in the sealing position.
When the rocker arm 20 rotates from the position I to the position II and the crank 18 rotates anticlockwise, the hinge four 17 should slide in the circular sliding groove 25 of the crank 18, the vent valve connecting rod 16 does not move, and the vent valve clack 15 is still in the opening position. If the friction force between the four hinges 17 and the circular sliding groove 25 of the crank 18 is too large at this time, the four hinges 17 can not slide smoothly in the circular sliding groove 25 of the crank 18, so as to drive the vent valve connecting rod 16 to move, so that the valve clack 15 of the vent valve is close to the closing position, even completely closed, the ventilation capacity of the vent valve is affected, and the side plate vent valve can not work normally. Accordingly, the edge panel vent valve further includes a vent valve return spring 10, as shown in FIG. 1. The vent valve return spring 10 is a large spring and is provided between the vent valve flap 15 and the vent valve support 11. When the friction force is large and the hinge four 17 does not slide from the first end to the second end of the circular sliding groove 25, namely the hinge four 17 drives the valve flap 15 of the vent valve to move upwards, the return spring 10 of the vent valve correspondingly generates a resistance force downwards, so that the friction force is overcome, the valve flap 15 of the vent valve is prevented from moving upwards, the adverse effect of the friction force between the hinge four 17 and the circular sliding groove 25 of the crank 18 is avoided, and the device can normally operate.
May be set to a state slightly larger than the frictional force. Because the manual control crank rotation is adopted, after the hinge four 17 slides to the second end of the circular sliding groove 25, the vent valve return spring 10 can not influence the rotation of the crank 18, so that the valve clack 15 of the vent valve can normally carry out the closing operation.
The working principle is as follows:
the manual oil gas recovery side plate vent valve for oil gas recovery of the oil tank truck can be set to be a manual control valve or an electric control valve. When the valve is a manual control valve, the oil gas recovery side plate vent valve is in three working states by operating the handle 23 of the flexible shaft controller. The handle 23 of the flexible shaft controller has three working positions which correspond to the three gears of the rocker arm 20 respectively. The first position is in a transportation state (oil gas recovery valve, side plate vent valve open), the second position is in an oil gas atmosphere state (oil gas recovery valve open, side plate vent valve open), and the third position is in an oil gas recovery state (oil gas recovery valve open, side plate vent valve closed), as shown in fig. 7.
When the handle 23 of the flexible shaft controller is rotated to the position I, the rocker arm 20 is driven to rotate to the position I. At this time, as shown in fig. 1 or 2, the oil gas recovery side plate ventilation integrated valve has the recovery valve clack 1 in the closed position and the ventilation valve clack 15 in the open position. At this time, the oil tank interior a and the valve cavity B are not communicated, and the valve cavity B and the atmospheric air position C are communicated, that is, the recovery valve is closed and the breather valve is opened, and this state is in the oil transportation state.
When the flexible shaft control handle 23 is rotated to the position II, the rocker arm 20 is rotated to the position II from the position I, and the crank rotates anticlockwise. The crank 18 drives the valve rod 4 of the recovery valve and the valve clack 1 of the recovery valve to move downwards through the connecting rod 6 of the recovery valve, and the recovery valve is opened. Since the crank 18 is connected to the vent valve connecting rod 16 through the four hinges 17, when the crank 18 rotates, the four hinges 17 slide in the circular sliding grooves 25 of the crank 18, the vent valve connecting rod 16 does not move, and the vent valve clack 15 is still in the opening position. At the moment, the inside A of the oil tank is communicated with the valve inner cavity B, the valve inner cavity B is communicated with the air through position C, namely the oil gas recovery valve is opened, the side plate vent valve is opened, and the state is in an oil gas emission operation state without an oil gas recovery condition.
When the flexible shaft control handle 23 is continuously rotated to the position III, the rocker arm 20 is rotated to the position III from the position II, the crank 18 drives the valve rod 4 of the recovery valve and the valve clack 1 of the recovery valve to continuously move downwards through the connecting rod 6 of the recovery valve, and the recovery valve is still in an opening state. At the same time, the crank 18 drives the vent valve stem 12 and the vent valve clack 15 to move upwards together through the vent valve connecting rod 16, and the vent valve is closed. At the moment, the inside A of the oil tank is communicated with the valve inner cavity B, the valve inner cavity B is not communicated with the atmosphere position C, and the inside A of the oil tank is communicated with the oil-gas system pipeline D through the valve inner cavity B. Namely, the recovery valve is opened, the vent valve is closed and opened, and the state is in an oil gas recovery operation state.
When light fuel oil is filled into the tank from the bottom of the tank, the oil-gas recovery side plate vent valve is manually controlled through the flexible shaft controller, so that the oil-gas recovery valve is opened, the side plate vent valve is closed, and oil gas in the tank can enter an oil-gas recovery system through a pipeline connected to the outlet end of the oil-gas recovery valve. Under the condition of no recovery, the oil gas recovery side plate vent valve can be manually controlled, so that the oil gas recovery valve and the side plate vent valve are both in an open state, and oil gas can be discharged to the atmosphere. At the usual state of not adorning oil, manual control oil gas recovery sideboard breather valve makes its oil gas recovery valve be in the closed condition, and sideboard breather valve is in the open mode, reduces the volatile emission of oil gas.
The fixed connection which is not specified can be a connection mode such as riveting, welding, bolt connection and the like, a movable connection can be a connection mode such as hinging and the like.
