BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 is a structural schematic view of the movable connecting device of the oil additive.

[0012] Figure 2 is a sectional view of the pipe fitting in the movable connecting device of the oil additive. DETAILED DESCRIPTION

[0013] The technical scheme in the embodiments of the present application will be described below with reference to the drawings.

[0014] As shown in Figure 1 and Figure 2 A movable connecting device of an oil additive includes a dry valve 10 and a filling machine 11 connected together through a pipe fitting, the pipe fitting includes a sleeve 1 and a joint pipe 2, one end of the joint pipe 2 is connected to the end of the dry valve 10 through a flange 3, the other end of the joint pipe 2 is connected to the open end of the sleeve 1, the center line of the joint pipe 2 and the center line of the sleeve 1 are not on the same straight line, one side of the sleeve 1 is provided with an air inlet valve 4 in communication therewith, the other side of the sleeve 1 is provided with an infusion valve 5 in communication therewith, and the output end of the filling machine 11 is connected to the infusion valve 5, and the bottom of the filling machine 11 is provided with a universal wheel 9.

[0015] In the embodiment, the dry valve 10 is used to connect the pipe with the oil inlet of the oil tank truck, to ensure the sealing of the connection, and the filling machine 11 is the existing liquid filling equipment, which can accurately measure the liquid flow and accurately fill it. The filling machine 11 moves to the oil depot equipment by using the universal wheel 9 to obtain and store the additive. According to the actual oil storage capacity of the oil tank truck, the additive filling amount is controlled by the filling machine 11, the additive is output according to the corresponding filling amount, and the additive is output to the oil tank of the oil tank truck through the liquid delivery valve 5, the sleeve 1, the joint pipe 2, the dry valve 10 and the oil inlet, to realize the rapid addition of the additive to the oil tank truck. The appropriate addition of the additive can ensure that the additive is uniformly mixed with the gasoline, and the excellent gasoline quality is obtained. The combination of the pipe and the dry valve 10 realizes the adaptive connection between the output end of the filling machine 11 and the oil inlet of the oil tank truck, and forms a closed conveying channel, which effectively avoids the leakage of gasoline or additive, and at the same time, the addition of the additive can be realized without approaching the oil depot.

[0016] It should be noted that since the oil inlet of the oil tank truck is horizontally oriented, the pipe is installed behind the oil inlet of the oil tank truck through the dry valve 10, and the sleeve 1 is in an inclined downward state. After the additive enters the sleeve 1, it can smoothly flow into the oil tank of the oil tank truck under the action of gravity, to ensure complete addition of the additive.

[0017] It should be understood that the liquid delivery valve 5 and the dry valve 10 can form a closed space inside the sleeve 1 and the joint pipe 2. After the additive injection is completed, the suction equipment is connected to the liquid delivery valve 5, then the internal space of the sleeve 1 and the joint pipe 2 is sucked to negative pressure, and then the inlet valve 4 is opened. The residual additive inside can be discharged outward through the liquid delivery valve 5, to realize complete recovery and avoid environmental pollution.

[0018] It can be understood that the flange 3 can be detachably connected with the dry valve 10, so as to clean and maintain the pipe as a whole.

[0019] The inner diameter of the joint pipe 2 is greater than that of the sleeve 1, a trumpet-shaped transition pipe 6 is arranged between the joint pipe 2 and the sleeve 1, the wide end of the transition pipe 6 is connected to the other end of the joint pipe 2, and the narrow end of the transition pipe 6 is connected to the open end of the sleeve 1. The trumpet-shaped transition pipe 6 can smoothly connect the sleeve 1 and the joint pipe 2, to ensure that the additive smoothly reaches the oil inlet of the oil tank truck, and to realize stable injection of the additive.

[0020] The outer side of the joint pipe 2 is provided with a transparent observation window 7. The transparent observation window 7 is made of tempered glass or organic glass. The transparent observation window 7 facilitates the oil station personnel to observe the injection condition of the additive and the filling amount of the additive in real time, to ensure that the additive operation is stably carried out, and to be handled in time in case of emergency.

[0021] The output of the filling machine 11 is connected to the delivery valve 5 by means of a hose 8. The auxiliary delivery of the hose 8 allows the operator of the filling machine 11 to be at a safe distance and to add the additive to the tank truck.
