[0019] The present application will be further described in combination with the drawings and specific embodiments.
[0020] Referring toFigures 1-4 The technical scheme adopted in the specific embodiment is shown: a full-automatic pressure and weight control heptafluoropropane filling machine, comprising a base 1 and a lifting support 4 fixedly arranged on the base 1, a horizontal moving support 5 fixedly arranged on the lifting support 4, a horizontal moving block 6 slidingly arranged on the horizontal moving support 5, and a filling head 7 fixedly arranged on the horizontal moving block 6. The filling head 7 comprises a pump air machine 71 and a gas pipe interface 72 arranged at the top end of the pump air machine 71. The bottom end of the pump air machine 71 is provided with a closed filling pipe 73. The closed filling pipe 73 comprises a pipe body 731 and an opening and closing nozzle 732 arranged at the lower end of the pipe body 731. The opening and closing nozzle 732 is provided with a penetrating slot at the middle section. The top end of the opening and closing nozzle 732 is provided with a first torsional spring 733 which is movably clamped with the lower end of the pipe body 731 through the first torsional spring 733. The closed filling pipe 73 is automatically closed after filling heptafluoropropane. In use, the fire-fighting container is placed on the base 1, and the pipeline connected with the heptafluoropropane container is connected to the gas pipe structure 72 of the filling head 7. At this time, the position of the filling head 7 can be adjusted through the lifting support 4 and the horizontal moving block 6. After the closed filling pipe 73 is inserted into the fire-fighting container, the heptafluoropropane is pumped into the pipe body 731 of the closed filling pipe 73 through the pump air machine 71, and moves downward along the pipe body 731. The gas pressure pushes the opening and closing nozzle 732, and the first torsional spring 733 is twisted to generate elastic force. At this time, the slot at the bottom of the opening and closing nozzle 732 is opened, and the heptafluoropropane is filled into the fire-fighting container. After the filling is completed, the pump air machine 71 stops working. At this time, the opening and closing nozzle 732 is reversed by the elastic force of the first torsional spring 733, so as to close and seal the lower end of the pipe body 731. In this way, the residual heptafluoropropane in the pipe body 731 after the filling is completed is prevented from leaking out, thereby reducing the waste of heptafluoropropane and reducing the pollution of the surrounding air;
[0021] The base 1 is further provided with a weighing machine 2, and the weighing machine 2 is provided with a placing tray 3. The heptafluoropropane in the fire-fighting container can be weighed by the weighing machine 2, so as to facilitate the control of the filling amount.
[0022] The opening and closing nozzle 732 is provided with a silica gel block 734 at the middle slot, so as to make the sealing effect of the opening and closing nozzle 732 better after being closed.
[0023] The bottom of the inner cavity of the pipe body 731 is provided with an inner cavity closer 735, which comprises a middle shaft body 21 fixedly arranged at the bottom of the inner cavity of the pipe body 731 and a close plate 23 arranged at both sides of the middle shaft body 21 and extending downward while the end portion thereof abuts and closes the inner wall of the pipe body 731, and the end portion of the close plate 23 close to the middle shaft body 21 is provided with a second torsional spring 22, and the close plate 23 is movably clamped with the side wall of the middle shaft body 21 through the second torsional spring 22, and in the process of filling, the close plate 23 is impacted by the flow pressure of the heptafluoro-propane gas, so that the second torsional spring 22 is twisted and loses the abutment with the pipe body 731, at this time, the heptafluoro-propane gas can flow out, and after the filling is completed, the close plate 23 is reversed through the second torsional spring 22, and then the pipe body 731 is quickly closed again through the close plate 23, which is favorable for further improving the sealing performance and further reducing the heptafluoro-propane leakage after the filling is completed.
[0024] The top end of the middle shaft body 21 is provided with a semispherical guide block 25, which is favorable for enabling the flowing heptafluoro-propane to move to both sides better and reducing the resistance when the gas moves.
[0025] The upper surface of the close plate 23 is provided with a water-drop-shaped pressure groove 24, which is favorable for improving the extrusion force of the heptafluoro-propane after impacting the close plate 23, and then the close plate 23 can swing faster.
[0026] The working principle of the utility model is: when the utility model is used, the fire-fighting container is placed on the base 1, and the pipeline connected with the heptafluoro-propane container is connected to the air pipe structure 72 of the filling head 7, at this time, the position of the filling head 7 can be adjusted through the lifting support 4 in cooperation with the transverse moving block 6, and after the closed filling pipe 73 is inserted into the fire-fighting container, the heptafluoro-propane is pumped into the pipe body 731 of the closed filling pipe 73 through the air pump 71, and moves downward along the pipe body 731, pushes away the opening and closing nozzle 732 through the air pressure, and makes the first torsional spring 733 be twisted to generate elastic force, at this time, the slot at the bottom of the opening and closing nozzle 732 is opened, and then the heptafluoro-propane is filled into the fire-fighting container, after the filling is completed, the air pump 71 stops working, at this time, the opening and closing nozzle 732 is reversed through the elastic force of the first torsional spring 733, so that it is closed and closes the lower end of the pipe body 731, thereby avoiding the residual heptafluoro-propane in the pipe body 731 from leaking out after the filling is completed, reducing the waste of heptafluoro-propane and reducing the pollution of the surrounding air.
