Abstract
The utility model relates to an oil-gas recovery self-sealing oil gun which comprises a gun body, an oil inlet channel, a main valve, a control valve, a gun barrel component, a gun holder component and a handle component, wherein an oil-gas recovery hole is disposed on the gun barrel component, an oil-gas recovery pipe is arranged in the oil inlet channel, an oil-gas recovery channel is arranged in the gun holder component, and the both ends of the oil-gas recovery channel are respectively communicated with the oil-gas recovery hole on the gun barrel component and the oil-gas recovery pipe in the oil inlet channel. The utility model has the advantages of simple manufacturing process, small volume, low cost, and the like, and is suitable for the oil gun in the oil filling station.
Description
Technical field
The utility model relates to a kind of bunkering facilities, specifically about a kind of self-sealing nozzle with recovery oil gas.
Background technology
Oil gas reclaims Oil gun with automatic cutoff device and is made up of parts such as rifle body, Handleset, main valve, control cock, draught damper, oil outlet pipe oil gas return flow lines, the last film chamber of control cock is communicated with the negative pressure chamber of draught damper and the pore of oil outlet pipe end respectively, in refueling process, gas flows out simultaneously in the air cavity that oil stream drives with draught damper negative pressure chamber links to each other, at this moment, the pore of oil outlet pipe end provides circulating air.When filling it up with oil, the pore of oil outlet pipe end is stopped up by oil, and the jet action of draught damper makes the last film chamber of control cock produce negative pressure, drives the control cock action, by the control handle assembly main valve is closed.The oil gas that produces in refueling process is recovered to petrol storage tank by the oil gas return flow line.As patent publication No. is that the oil gas of CN1569533 reclaims self-styled nozzle, its structure is by the rifle body, oil inlet passage, main valve, control cock, reflux valve, oil outlet pipe and Handleset are formed, 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 stifle is set in the oil outlet pipe rearward end, in refueling process, stifle is enclosed in reservoir port, gaseous state oil is recovered in the oil tank by oil gas recovery holes and oil gas recovery approach, has prevented that gaseous state oil is dispersed into atmosphere and causes environmental pollution, potential safety hazard and energy dissipation.Its weak point is that the oil gas recovery approach is manufactured on the rifle body, has increased rifle body volume and cost of product, and the manufacturing process complexity.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, provides that a kind of volume is little, cost is low, the simple oil gas of technology reclaims self-styled nozzle.
The technical scheme that realizes the utility model purpose comprises rifle body, oil inlet passage, main valve, control cock, barrel assembly, gun stock assembly and Handleset composition, on barrel assembly, be shaped on the oil gas recovery holes, be provided with the oil gas Through Flow Line (TFL) in the oil inlet passage, mainly be in the gun stock assembly, to make the oil gas recovery approach, these oil gas recovery approach two ends respectively with barrel assembly on the oil gas recovery holes and the oil gas Through Flow Line (TFL) in the oil inlet passage be connected.
In above technical scheme, be provided with boiler check valve between the oil gas Through Flow Line (TFL) in oil gas recovery approach and oil inlet passage.
The utility model beneficial effect compared with prior art is that the oil gas recovery approach is manufactured in the gun stock assembly, have manufacturing process simple, reduce small product size, reduce advantages such as cost of product.
