[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] See also Figure 1-2The utility model provides a technical solution of a multifunctional gas combined pressure reducing device: a multifunctional gas combined pressure reducing device, comprising a pressure reducing valve 1 and a selector 5, a first pressure gauge 2 and a second pressure gauge 3 are fixedly mounted on the top and bottom of the pressure reducing valve 1, the air inlet and air outlet of the pressure reducing valve 1 are respectively connected to a connecting pipe 9 and an air outlet connecting port 4, the connecting pipe 9 is connected to the selector 5, a first air inlet connecting port 7 and a second air inlet connecting port 8 are respectively provided on the upper and lower sides of the selector 5, a column core 10 is movably mounted in the selector 5, one end of the column core 10 passes through the selector 5 and is connected to a knob 6, a connecting pipe 11 is provided in the column core 10, a spring 12 is fixedly mounted in the right side wall of the pressure reducing valve 1, the end of the spring 12 is connected to a column head 13, and a pair of card slots 14 are provided in the selector 5 at the right side wall position of the column core 10.
[0018] Furthermore, the first pressure gauge 2 displays the outlet pressure value of the pressure reducing valve 1 , and the second pressure gauge 3 tests the inlet pressure value of the pressure reducing valve 1 .
[0019] Furthermore, the connecting pipe 11 is a vertical structure, connecting the first air inlet connection port 7 or the second air inlet connection port 8 and the connecting pipe 9 .
[0020] Furthermore, the column head 13 and the card slot 14 cooperate with each other. When the connecting pipe 11 is connected to the first air inlet connecting port 7 and the connecting pipe 9, the column head 13 is clamped in the top card slot 14. When the connecting pipe 11 is connected to the second air inlet connecting port 8 and the connecting pipe 9, the column head 13 is clamped in the bottom card slot 14.
[0021] Furthermore, the outer wall of the column core 10 is a smooth structure, and the outer wall of the column core 10 is tightly fitted and sealed with the inside of the gas outlet connection port 4 .
[0022] Furthermore, an arrow indicating the same connection direction as that of the connecting pipe 11 is engraved on the knob 6 .
[0023] Embodiment: When the device is in use, the first air inlet connection port 7 and the second air inlet connection port 8 are connected to two air supply tanks respectively, and the air outlet connection port 4 is connected to the air pipeline.
[0024] When the knob 6 is rotated, the column core 10 will be driven to rotate in the selector 5. When the column core 10 rotates to the connecting pipe 11 to fully connect the first air inlet connection port 7 or the second air inlet connection port 8 with the connecting pipe 9, the elastic force of the spring 12 pushes the column head 13 to snap into the slot 14. At this time, a sound of complete snapping can be heard, and a certain resistance will be given to prevent the rotation of the knob 6, so as to prompt the operator that the passage is fully open.
[0025] When it is necessary to switch the gas supply tank, turn the knob 6 forcefully. Since the connection between the slot 14 and the column head 13 is a hemispherical structure, the column head 13 will retract inward along the arc surface of the slot 14 under a certain force. Continue to turn the knob 6 until you hear the "click" sound of the column head 13 and the slot 14 being fully engaged again, or the knob 6 feels rotational resistance, or the shear head on the knob 6 points completely upward or downward, and the switching of the gas supply tank is completed.
[0026] The device can switch between two gas supply tanks, solving the problem that the gas supply system cannot be used during the time when one gas supply tank is dismantled and then installed after the gas is used up, thereby increasing efficiency and reducing downtime costs.
[0027] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.
