Description

Oil gun main valve

Technical Field

The utility model relates to an oil gun, in particular to oil gun main valve.

Background

The fuel gun is the terminal for the fuel dispenser output in the service station, i.e. the part that touches the vehicle's fuel tank. Commonly used are self-sealing fuel guns and compound fuel guns. The traditional product is provided with the rubber sleeve, but the rubber sleeve still has a gap during installation, which easily causes the subsequent use to open the rubber, and influences the use and the product service life. Besides, the main valve structure of the oil gun is too simple to arrange and is one of the factors of degumming.

SUMMERY OF THE UTILITY MODEL

Not enough to current technique, the utility model provides an oil gun main valve.

In order to realize the purpose, the utility model adopts the technical scheme that: the utility model provides an oil gun main valve, includes the valve body, the valve body includes disk seat and valve barrel, the complete cladding disk seat of valve barrel, the valve barrel is made by rubber materials, the disk seat has the front stall and the back seat that central authorities link up, be equipped with a plurality of trompils on the back seat, be equipped with the dog on the central side wall of back seat.

The front seat and the rear seat are of circular truncated cone-shaped structures, and the diameter of the rear seat is smaller than that of the front seat.

And the end surface of the front seat is provided with a slot.

The opening is formed in the inclined plane of the circular truncated cone of the rear seat.

The stop blocks are uniformly arranged at three positions along the circumference by taking the axis of the rear seat as the center.

The stop block is of a step-shaped structure.

The open slot is communicated with the open hole.

The utility model has the advantages that: the utility model provides a pair of oil gun main valve adopts full cladding structure, cooperates deep parcel and the cross of many places simultaneously and links to each other, improves the reliability and the stability of gum cover parcel greatly.

Detailed Description

As shown in fig. 1 to 3, the main valve of the oil gun comprises a valve body 1, wherein the valve body 1 comprises a valve seat 2 and a valve sleeve 3, the valve sleeve 3 completely covers the valve seat 2, the valve sleeve 3 is made of a rubber material, and is completely covered by the rubber material, so that the covering reliability is ensured, and the rubber material has good elasticity, strong skid resistance and a firm structure. The valve seat 2 is provided with a front seat 4 and a rear seat 5 which are communicated with each other in the center, the rear seat 5 is provided with a plurality of holes 6, and the central side wall of the rear seat 5 is provided with a stop dog 7. The valve sleeve 3 is inserted through the opening 6 into the valve seat 2, and the valve seat 2 is connected to the valve sleeve 3 more tightly. The design of dog 7 lies in that the antithetical couplet uses with other structures of valve body 1 cooperation, plays reinforced structure intensity and stability, also can play the effect of blockking great impurity.

The front seat 4 and the rear seat 5 are both in a circular truncated cone-shaped structure, and the diameter of the rear seat 5 is smaller than that of the front seat 4. The front seat 4 is impacted by oil liquid in a straight surface, so that the size of the front seat is wider, and meanwhile, the truncated cone-shaped structure is also beneficial to prolonging the service life.

The end face of the front seat 4 is provided with a slot 8, the front end of the front seat 4 is sunken in the center due to the design of the slot 8, the front end of the front seat and the valve sleeve 3 are higher in level, and the wrapping connectivity is improved.

The opening 6 is formed in the inclined plane of the circular truncated cone of the rear seat 5, and the direction of the opening 6 is inclined relative to the axis, so that the valve sleeve 3 is more suitable for the installation environment and is not easy to deform and separate.

The stop blocks 7 are uniformly arranged at three positions along the circumference by taking the axis of the rear seat 5 as the center, and the connecting line between every two stop blocks and the circle center forms an included angle of 120 degrees, so that the structure is simple, the processing is convenient, and the symmetry is uniform.

The stop 7 is of a stepped structure, and similarly, the matching level of the valve sleeve 3 and the valve seat 2 is enhanced, for example, the stability in the radial direction of the opposite inner side can be increased.

The open slot 8 is communicated with the open hole 6, so that the valve sleeve 3 is not only coated, but also directly bound on the valve seat 2 through insertion. Such a structure may be integrally formed by injection molding, or may be otherwise implemented, and will not be described or limited herein.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
