Abstract
The utility model discloses an oil-gas recovering joint, which comprises a triangular support, a rotating joint, a cone and a sleeve, and is characterized in that: a sealing section with a sealing groove is formed at the front end of the triangular support; three support arms are arranged at the back end of the triangular support, and are fixed on the inner wall of the front end of the rotating joint; and the core is fixedly assembled or rotationally assembled in the rotating joint. The oil-gas recovering joint has the advantages that: the flexibility ratio of the rotating joint can be enhanced; dynamic sealing between a gas return position inside an oil gun and the triangular support of the oil-gas recovering joint is replaced by static sealing, so that sealing property is enhanced, and the probability of pumping of gasoline into a pump by a gas return pipe is remarkably lowered; and meanwhile, the service life of an oil gas recovering hose is prolonged, air quality is improved, energy is saved, and the potential safety hazard is reduced.
Description
Technical field
The utility model belongs to the connecting device of a kind of nozzle and fuel filler pipe, and particularly a kind of oil gas reclaims joint.
Background technology
When automobile refuels at petrol service station, utilize the special device on the oil gun, will can overflow to loose by automotive oil tank originally imports in the oil tank via nozzle, the electrical motor of bleeding in airborne oil gas.The inner return-air of oil gas recovery rubber tube joint and oil gun position seal form is dynamic seal both at home and abroad at present; When refueling oil gun often rotation cause gasoline to prolong muffler to be gone in the fuel charger by pumpback; The direct result of bringing is that the circulating vacuum pump is scrapped, the petrol service station cisco unity malfunction.According to incompletely statistics the whole nation 1 year thus reason cause ultra over thousands of of fuel charger cisco unity malfunction.Press every vacuum pump price of conservative estimate about in the of 7000 yuan, the direct loss that cause are near ten million more than.Loss is existing makes improvement to remedy existing design-calculated weak point to oil gas recovery joint in order to practice thrift.
Summary of the invention
The purpose of the utility model provides a kind of oil gas and reclaims joint, can improve the flexibility ratio of SAH, changes inner return-air position of oil gun and oil gas recovery joint spider seal form into static sealing by dynamic seal (packing); Make its sealing property better; Significantly reduce gasoline and drawn back the probability in the pump, increase the service life of oil gas recovery rubber tube simultaneously, improve air quality by muffler; Reduce potential safety hazard, energy savings.
The purpose of the utility model realizes through following technical scheme: it comprises spider, SAH, fuse and sleeve; It is characterized in that: the spider front end is the seal section of band seal groove; The rear end is three support arms, and three support arms are fixed on the SAH front inner wall; At SAH internal fixation assembling fuse or rotating group cored.
Three keyways are set on the above-mentioned SAH front inner wall, and three support arm plug-in mountings are fixed in three keyways of SAH.
Three support arms of above-mentioned spider are adhesively fixed on the SAH front inner wall.
Three support arms of above-mentioned spider are fixed on the SAH front inner wall through being threaded.
Three support arms of above-mentioned spider are fastened on the SAH front inner wall through jump ring.
Rotating group cored is provided with the rubber sealing groove in the above-mentioned SAH on the fuse, seals through seal ring between fuse and the SAH.
The whole fuse that connects in the above-mentioned SAH.
The utility model has the advantages that: can improve the flexibility ratio of SAH, change inner return-air position of oil gun and oil gas recovery joint spider seal form into static sealing by dynamic seal (packing), make its sealing property better; Significantly reduce gasoline and drawn back the probability in the pump by muffler; Increase the service life of oil gas recovery rubber tube simultaneously, improve air quality, energy savings; Reduce potential safety hazard, energy savings.
