Abstract
The utility model relates to an oil-gas recovery self-sealing refueling gun, which comprises a gun body, an oil inlet passage, a main valve, a control valve, a reflux valve, an oil outlet pipe and a handle component. The oil-gas recovery self-sealing refueling gun is characterized in that an oil-gas recovery hole and an oil-gas recovery passage communicated with the same are arranged on the oil outlet pipe, the oil-gas recovery passage is communicated with an oil-gas recovery pipe via an oil-gas recovery passage fabricated on the gun body, a blank cap is arranged at the rear end of the oil outlet pipe, and during refueling process, an oil tank opening is sealed by the blank cap, gas-state oil is recovered to an oil tank via the oil-gas recovery hole and the oil-gas recovery passage, thereby preventing gas-state oil scattering to the atmosphere to cause environmental pollution, potential safety hazards and energy waste. The oil-gas recovery self-sealing refueling gun is safe, environment-friendly and energy-saving, and is a novel refueling device of automobile filling stations.
Description
Technical field
The utility model relates to a kind of petrol service station bunkering facilities, specifically about a kind of nozzle.
Background technology
At present, when each petrol service station is to automobile fuel filler, all adopt the self-sealing nozzle both at home and abroad, this nozzle has the function of energy SELF CL when the fuel tank of automobile is filled it up with oil.Its structure mainly is made up of rifle body, oil inlet passage, main valve, control cock, reflux valve, oil outlet pipe and Handleset, and main valve is installed in the oil inlet passage, and its on off state is by the location status control of Handleset.The end of the valve rod of control cock is connected with an end of handle, the up-and-down movement of valve rod is controlled by control diaphragm, diaphragm chamber above the control diaphragm is communicated with to pore by through hole on the rifle body and on the gun barrel and oil outlet pipe front end, and be communicated with the oil outlet pipe internal channel by the rifle body, in refueling process, the negative pressure that oil stream produces diaphragm chamber is given the air pressure balance of pore inspiration, when fuel tank is filled it up with oil, the pore of giving of oil outlet pipe front end is stopped up by oil, the negative pressure that oily stream produces diaphragm chamber is inhaled moving control diaphragm, and moves on the drive control cock valve rod, changes the location status of Handleset, main valve is closed, realize self-styled function.But, domestic and international existing self-sealing nozzle, in refueling process, along with gas and oil enters fuel tank, the gaseous state oil in the fuel tank can be dispersed in the atmosphere and go, and forms environmental pollution and potential safety hazard, also causes the waste of the energy, and this is the subject matter that existing product exists.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, provides a kind of safety, environmental protection, energy-conservation oil gas to reclaim self-styled nozzle.
The technical scheme that realizes the utility model purpose comprises the rifle body, oil inlet passage, main valve, control cock, reflux valve, oil outlet pipe and Handleset are formed, main valve is installed in the oil inlet passage, main valve valve rod end withstands on the handle, one end of handle is connected with the end of the valve rod of control cock, diaphragm chamber above the control diaphragm of control cock is communicated with to pore by through hole on the rifle body and on the oil outlet pipe and oil outlet pipe front end, and be communicated with the oil outlet pipe internal channel by the rifle body, it mainly is the oil gas recovery approach that on oil outlet pipe, is shaped on the oil gas recovery holes and communicates with it, this oil gas recovery approach is communicated with the oil gas Through Flow Line (TFL) by made oil gas recovery approach on the rifle body, and in the oil outlet pipe rearward end stifle is set.
The utility model beneficial effect compared with prior art is that the oil gas recovery holes is set on oil outlet pipe, this oil gas recovery holes is communicated with the oil gas Through Flow Line (TFL) by the oil gas recovery approach on oil outlet pipe and the rifle body, simultaneously stifle is set in the oil outlet pipe rearward end, in refueling process, stifle has been sealed reservoir port, gaseous state oil can only be recovered in the oil tank by oil gas recovery holes and oil gas recovery approach, prevented that gaseous state oil is dispersed into atmosphere and causes environmental pollution, potential safety hazard and energy dissipation, had safety, environmental protection and advantage such as energy-conservation.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model.
The specific embodiment
Oil gas as shown in Figure 1 reclaims self-styled nozzle, comprise rifle body 1, oil inlet passage 2, main valve 3, control cock 4, reflux valve 5, oil outlet pipe 6 and Handleset 7 compositions, main valve 3 is installed in the oil inlet passage 2, valve rod 8 ends of main valve 3 withstand on the handle, one end of handle is connected with the end of control cock 4 pull bars 9, diaphragm chamber 11 above the control diaphragm 10 of control cock 4, by on the rifle body 1 and the pore 14 of giving of through hole 12,13 and oil outlet pipe 6 front ends on the oil outlet pipe 6 be communicated with, and pass through rifle body 1 and be communicated with oil outlet pipe 6 internal channels.The oil gas recovery approach 16 that is shaped on oil gas recovery holes 15 and communicates with it on oil outlet pipe 6, this oil gas recovery approach 16 is communicated with the oil gas Through Flow Line (TFL) by made oil gas recovery approach 17 on the rifle body 1, and in oil outlet pipe 6 rearward end stifle 20 is set.Stifle 20 is made by elastomeric material, is bowl shaped structure, can inhale to be enclosed on the automobile fuel tank port when refueling.Valve seat 18 fixed seal connections of reflux valve 5 are in the exit end of oil inlet passage 2, and make through hole 19 on valve seat 18, these through hole 19 two ends respectively with rifle body 1 on through hole 12 and the through hole 13 on the oil outlet pipe 6 be connected.Oil gas recovery holes 15 is positioned to pore 14 rear sides, is made up of several same circular hole.Its principle of work is: when refueling, oil outlet pipe 6 inserts fuel tank, the stifle 20 of its rear end covers reservoir port, manually pull on handle, the valve rod 8 of handle hand jack-up main valve 3 is opened main valve 3, oil stream enters fuel tank from oil inlet passage 2, main valve 3, reflux valve 5, oil outlet pipe 6, the position of handle hand assembly meeting self-locking handle.Simultaneously, along with entering of oily medium, oil gas in the fuel tank will be got back to the oil gas Through Flow Line (TFL) from the oil gas recovery approach 17 on the oil gas recovery holes 15 on the oil outlet pipe 6 and oil gas recovery approach 16 and the rifle body 1, and by the vacuum pump that is installed on the oil gas reclaim line oil gas will be recovered to the oil tank system.When fuel tank was filled it up with oil, the pore 14 given of oil outlet pipe 6 front ends was lived by oil sealing, along with flowing of oil stream, the negative pressure that produce in the diaphragm chamber 11 are upwards inhaled control diaphragm 10, make by the control cock assembly on the pull bar 9 of control cock 4 to draw, and the pulling handle restore handle, main valve 3 is closed, and realizes self-styled function.
