Special gases have high requirements for ease. Most special gases are flammable, explosive, highly toxic, and corrosive. In order to safely transport and use these dangerous gases, the container needs to have good pressure resistance or corrosion resistance. Therefore, these special gases need to be stored in gas cylinders.

[0019] (III) Beneficial effects

[0020] The utility model provides a gas cylinder valve switch device with adjustable torque, which has the following beneficial effects:

[0021] (1) The laser sensor of the utility model detects the position of the hand valve seat relative to the gas cylinder valve in real time, and realizes the alignment of the hand valve seat and the gas cylinder valve under the action of the control console. The first transmission member of the driving mechanism is connected to the second transmission member of the functional mechanism through a belt, and the driving member of the driving mechanism drives the first transmission member to rotate.

Therefore, if the hand valve seat is completely aligned with the notch of the gas cylinder valve, the flexible mechanism will not work; if the hand valve seat is not completely aligned with the notch of the gas cylinder valve, the rod will retract the spring of the flexible mechanism after receiving the extrusion force, thereby generating a downward force. Since the front end of the rod is arc-shaped, when the rod receives the downward force, it will rotate, so that the hand valve seat is completely aligned with the notch of the gas cylinder valve, thereby optimizing the alignment method of the hand valve seat and the gas cylinder valve, and ensuring that the hand valve seat can be accurately matched with the gas cylinder valve.

[0048] The working principle of the torque-adjustable gas cylinder valve switch device of the utility model is as follows:

[0049] The laser sensor 5 detects the position of the hand valve seat 33 relative to the cylinder valve in real time, and under the action of the console, the hand valve seat 33 is aligned with the cylinder valve. The first transmission member 24 of the driving mechanism 2 is connected to the second transmission member 34 of the functional mechanism 3 through a belt, and the driving member 21 of the driving mechanism 2 drives the first transmission member 24 to rotate. Therefore, the second transmission member 34 of the functional mechanism 3 rotates under the belt drive, and the second transmission shaft 32 also rotates.

Therefore, if the hand valve seat 33 is completely aligned with the notch of the gas cylinder valve, the flexible mechanism 4 will not work; if the hand valve seat 33 is not completely aligned with the notch of the gas cylinder valve, the rod 36 will retract the spring 41 of the flexible mechanism 4 after receiving the extrusion force, thereby generating a downward force. Since the front end of the rod 36 is arc-shaped, when the rod 36 receives the downward force, it will rotate, so that the hand valve seat 33 is completely aligned with the notch of the gas cylinder valve, and the alignment method of the hand valve seat 33 and the gas cylinder valve is optimized, ensuring that the hand valve seat 33 can be accurately matched with the gas cylinder valve.

[0051] A pressure sensor 6 is provided on the gas cylinder valve, and the pressure sensor 6 is connected to the control console. The control console can realize precise adjustment of the hand valve seat 33 and the gas cylinder valve according to the feedback value of the pressure sensor 6. At the same time, when the control console drives the driving member 21 to adjust the gas cylinder valve for many times, if the pipeline pressure of the gas cylinder is still lower than the set value, it is judged that the gas cylinder is faulty, and the driving member 21 rotates in the opposite direction to close the gas cylinder valve, thereby optimizing and improving the processing method of the hand valve seat 33 in the process of adjusting the gas cylinder valve, so that the gas cylinder valve can be better adjusted.
