[0010] Liquid cylinder 1, feed pipe 2, filling valve 3, air return pipe 4, control valve group 5, first branch 6, second branch 7, first air path 8, second air path 9, ring pipe 10, guide plate 11, filling nozzle 12. DETAILED DESCRIPTION

[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0012] See Figure 1 As shown, this specific embodiment adopts the following technical scheme: it comprises a liquid cylinder 1, a feed pipe 2, a filling valve 3, a return pipe 4 and a control valve group 5; the liquid cylinder 1 is connected to the filling valve 3 through the feed pipe 2, the return pipe 4 is inserted and fixed in the filling valve 3, the bottom of the return pipe 4 is located in the filling nozzle 12 of the filling valve 3, the upper end of the return pipe 4 is sealed, and the side wall of the return pipe 4 is provided with a first branch 6 and a second branch 7, the two branches are 180 degrees along the center line of the return pipe 4, the first branch 6 is connected to a passage of the control valve group 5, the passage is connected to the liquid cylinder 1 through the first air path 8, and the second branch 7 is connected to another passage of the control valve group 5. This passage is connected to the ring tube 10 through the second air path 9, and the ring tube 10 is connected to the negative pressure device. During filling, one side passage of the control valve group 5 is opened, and the gas in the filling valve 3 enters the side passage through the return air pipe 4, enters the first air path 8 from this passage, and finally returns to the liquid cylinder 1; after the filling is completed, one side passage of the control valve group 5 is closed, and the other side passage is switched to open, and the gas in the filling valve 3 enters the other side passage through the return air pipe 4, enters the second air path 9 from the other side passage, and is drawn away by the ring tube 10.

[0013] A guide plate 11 is provided at the lower part of the return air pipe 4, and the guide plate 11 is welded to the outer wall of the return air pipe 4. The material entering the inner cavity of the filling valve 3 is guided to the inner wall of the filling nozzle 12 through the guide plate 11, and flows out of the filling nozzle along the inner wall, which facilitates filling and prevents splashing.

[0014] The working principle of the utility model is as follows: the material enters the filling valve 3 from the liquid cylinder 1 through the feed pipe 2, and the gas to be returned to the liquid cylinder 1 and the gas to be drawn out are switched through the control valve group 5, which is very convenient to use.

[0015] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
