Description
Technical Field
The utility model belongs to the technical field of the rubber tube joint, concretely relates to secondary vapor recovery system of filling station is with joint for rubber tube that has vapor recovery system function.
Background
Because of the evaporability of gasoline, each liter of gasoline naturally volatilizes oil gas with the volume of 600 to 800 times in the air. These hydrocarbons can create problems of unsafe conditions, environmental damage, and energy waste.
The oil gas recovery hose is a coaxial rubber hose consisting of a fuel hose for conveying fuel oil and an oil gas hose for recovering oil gas, the oil gas hose is arranged in the fuel hose, and the fuel oil is conveyed between the two hoses through an annular space.
In the production and manufacturing process, two ends of the oil gas hose and two ends of the fuel oil outer pipe are fixed together through special joints.
At present, the joint of the existing oil gas recovery hose assembly generally adopts a dynamic seal form, so that the rotation flexibility and the reliability of the joint part are required to be ensured when oil is filled.
The existing oil gas recovery joint adopts a clamp spring type or a ball type structure.
Jump ring formula structure is as shown in fig. 2, in the use, because the oil gun is rotatory and draw, produce frictional force and outside tensile force between the top of rotatory nut 2 and jump ring 1, because of both materials are different (rotatory nut 2 generally is the copper product, jump ring 1 is the manganese steel material) can cause the top of rotatory nut 2 to damage because of wearing and tearing, the whole life has been influenced greatly, the risk that also has 1 atress of jump ring to damage simultaneously, cause rotatory nut 2 to pull out the oil spout.
The ball formula structure is as shown in fig. 3, in the use, because of the rotation of oil gun, draw equally, uses the inside ball groove of certain time back joint to be scratched by ball 8, and ball 8 is obstructed in the ball inslot rotation of unevenness to cause rotatory nut 2 jamming or card to die, the ball 8 that more can appear when wearing and tearing are serious drops, and rotatory nut 2 pulls out the oil spout phenomenon.
Disclosure of Invention
The utility model discloses to above-mentioned problem, provide a safe and reliable's oil gas recovery is joint for rubber tube.
In order to realize the above object of the utility model, the utility model discloses a following technical scheme, the utility model discloses a fuel core bar, rotatory nut and sleeve, rotatory nut cup joints in fuel core bar front end, and the sleeve sets up in fuel core bar rear end, its characterized in that: the outer surface of the fuel core rod is provided with an annular groove corresponding to the position of the end face of the rear end of the rotating nut, a check ring is arranged in the annular groove, and the check ring is fixedly connected with the end face of the rear end of the rotating nut through a screw.
As a preferred scheme of the utility model, the inner surface of the rear part of the rotating nut is provided with a limit groove; and the fuel core bar is provided with a limiting platform matched with the limiting groove.
As another preferred scheme of the utility model, be provided with the sealing washer between fuel core bar surface and the rotatory nut internal surface.
Further, a sealing groove is formed in the outer surface of the fuel core rod; the sealing ring is arranged in the sealing groove.
Furthermore, the sealing ring is made of nitrile rubber.
The utility model has the advantages that: the utility model discloses a retaining ring is fixed rotatory nut on the fuel core bar, has replaced the jump ring, has avoided the potential safety hazard that brings because of the nut wearing and tearing that long-time the use caused and the jump ring rupture.
The utility model discloses a fixed knot constructs, can replace the fixed rotatory nut method of ball formula completely, has avoided because of the ball groove wearing and tearing that long-time use caused, makes the joint jamming or card die.
The utility model discloses fuel core bar and swivel nut's installation is convenient reliable more, when having avoided wearing and tearing, the jamming scheduling problem that causes because of long-time the use, has more improved its life greatly.
The utility model is used for the sealing washer of movive seal uses the nitrile rubber material, has improved sealing performance.
The utility model discloses can be applied to: the joint of the oiling machine oiling hose of the secondary oil gas recovery system of the gas station.
