Description
Technical field
The present invention relates to gauging device technical field, be specifically related to a kind of nozzle.
Background technology
As everyone knows, the nozzle that petrol service station uses generally is self-sealing oil pocket, and its principle is for when fuel oil fills fuel tank, and the ventilation mouth on oil gun blocked by fuel oil, thus vacuum valve cuts out, and jumps rifle.When but the fuel oil antifoam content due to unreasonable or a certain batch of the Oiltank structure design of a lot of vehicle is too low, because the generation of oil vacuole causes oil gun frequently to jump rifle in refueling process, impact oiling efficiency.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of oiling and produces the nozzle that oil vacuole frequently can not jump rifle.
The present invention overcomes the technical scheme that its technical matters adopts:
This nozzle, comprise body skin, be installed on the oil outlet pipe of body skin front end, be arranged at body skin inner and be connected to the valve housing of oil inlet, be movably set in the valve block in valve housing, to be installed in valve housing and the spring be positioned at above valve block, be installed on the pull bar bottom valve block, the handle and the automatically controlled flow regulating valve be installed in body skin and vacuum valve that are installed on bottom body skin is rotated by rotating shaft II, described automatically controlled flow regulating valve is connected to valve housing and vacuum valve by pipeline, the exit end of described vacuum valve is connected to oil outlet pipe, described oil outlet pipe lower end outer wall is provided with admission port, described admission port is connected to vacuum valve by the tracheae be arranged in oil outlet pipe, the bottom being fixed on pull bar is rotated in the front end of described handle by rotating shaft I, when spring in the raw time, oil inlet and the not conducting of automatically controlled flow regulating valve, in described vacuum valve, pressure sensor is installed, described pressure sensor and automatically controlled flow regulating valve are connected to controller.
In order to realize oil gun handle automatic locking in refueling process, the rear end of above-mentioned handle is provided with iron block, the side of described body skin is fixed with close to sensing, the top of described body skin and be positioned at directly over handle and be provided with proximity transducer, when handle is rocked to top, electromagnetic actuation after iron block is energized is fixed, and described electromagnet is connected to controller through relay, and described proximity transducer is connected to controller.
The invention has the beneficial effects as follows: oil outlet pipe is stretched in automotive oil tank pouring orifice during oiling, pull handle afterwards, handle rotates around rotating shaft II and moves valve block downwards to by pull bar, this Time Controller controls automatically controlled flow regulating valve and opens, can extension spring in the process that valve block moves down, now valve block can finally flow into through oil outlet pipe in the fuel tank of automobile through valve housing, automatically controlled flow regulating valve and vacuum valve successively due to the fuel oil moved down in oil inlet.When the foam produced due to refueling process admission port blocked vacuum valve be in negative pressure state close time, pressure sensor detects and is in negative pressure state, this Time Controller controls automatically controlled flow regulating valve throttling, but make oil outlet pipe continue fuel-displaced Extraction rate to reduce, the fuel-displaced oil vacuole that makes of high speed is avoided more easily to produce, in low speed refuels, oil vacuole slowly disappears, now vacuum valve recovers normal condition, controller can control automatically controlled flow regulating valve and tune up Extraction rate, therefore can solve the phenomenon generation that traditional self-sealing oil pocket frequently jumps rifle.After filling it up with oil, fuel oil is bending blocks admission port, and the pressure sensor now in throttle valve adjustment slow oiling final vacuum valve still detects negative pressure state, and this Time Controller controls automatically controlled flow regulating valve and bends locking, refuel and terminate, after loosing one's grip, handle resets under the action of the spring.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention will be further described.
This nozzle, comprise body skin 2, be installed on the oil outlet pipe 1 of body skin 2 front end, be arranged at body skin 2 inner and be connected to the valve housing 10 of oil inlet 11, be movably set in the valve block 8 in valve housing 10, to be installed in valve housing 10 and the spring 9 be positioned at above valve block 8, be installed on the pull bar 14 bottom valve block 8, the handle 17 and the automatically controlled flow regulating valve 7 be installed in body skin 2 and vacuum valve 5 that are installed on bottom body skin 2 is rotated by rotating shaft II 16, automatically controlled flow regulating valve 7 is connected to valve housing 10 and vacuum valve 5 by pipeline, the exit end of vacuum valve 5 is connected to oil outlet pipe 1, oil outlet pipe 1 lower end outer wall is provided with admission port 3, admission port 3 is connected to vacuum valve 5 by the tracheae 4 be arranged in oil outlet pipe 1, the bottom being fixed on pull bar 14 is rotated in the front end of handle 17 by rotating shaft I 15, when spring 9 in the raw time, oil inlet 11 and the not conducting of automatically controlled flow regulating valve, pressure sensor 6 is installed in vacuum valve 5, pressure sensor 6 and automatically controlled flow regulating valve 7 are connected to controller.During oiling, oil outlet pipe 1 is stretched in automotive oil tank pouring orifice, pull handle 17 afterwards, handle 17 rotates around rotating shaft II 16 and moves valve block 8 downwards to by pull bar 14, this Time Controller controls automatically controlled flow regulating valve 7 and opens, can extension spring 9 in the process that valve block 8 moves down, now valve block 8 can finally flow in the fuel tank of automobile through oil outlet pipe 1 through valve housing 10, automatically controlled flow regulating valve 7 and vacuum valve 5 successively due to the fuel oil moved down in oil inlet 11.When the foam produced due to refueling process admission port 3 blocked vacuum valve 5 be in negative pressure state close time, pressure sensor 6 detects and is in negative pressure state, this Time Controller controls the throttling of automatically controlled flow regulating valve 7, but make oil outlet pipe 1 continue fuel-displaced Extraction rate to reduce, the fuel-displaced oil vacuole that makes of high speed is avoided more easily to produce, in low speed refuels, oil vacuole slowly disappears, and now vacuum valve 5 recovers normal condition, and controller can control automatically controlled flow regulating valve 7 and tune up Extraction rate.After filling it up with oil, fuel oil is bending blocks admission port 3, and now flow regulating valve 7 regulates the pressure sensor 6 in slow oiling final vacuum valve 5 still negative pressure state to be detected, and this Time Controller controls automatically controlled flow regulating valve 7 and bends locking, refuel and terminate, after loosing one's grip, under the effect of spring 9, handle 17 resets.
The rear end of handle 17 is provided with iron block 18, the side of body skin 2 is fixed with proximity transducer 12, the top of body skin 2 and be positioned at directly over handle 17 and be provided with proximity transducer 12, electromagnet is connected to controller through relay, and proximity transducer 12 is connected to controller.When refueling, when upwards rotating with hand pinching handle 17, can trigger proximity transducer 12, controller now control relay adhesive, electromagnet 13 is energized and produces magnetic force, the iron block 18 at handle 17 rear is fixed, therefore now people need not pinching handle 17 again, improves the comfort level of oiling work, after oiling, controller control relay disconnects, and electromagnet 13 disconnects now handle 17 and can reset under the effect of spring 9 pulling force.
