Working principle:
a pneumatic quick-connection plug is arranged in each of the two first internal thread counter bores 103 and the second internal thread counter bores 104, then an air inlet pipe and an air outlet pipe are respectively connected into the two pneumatic quick-connection plugs, and then the opening of the through air flue 107 is closed; when the intake starts, the pressure gas enters the through air passage 107 through the first submerged air passage 105, then enters the corresponding one of the arc grooves 72 through one of the air vents 11, then enters the third counter bore 73 through each of the flow dividing holes 75 in the arc grooves 72, since the first stepped post 41 in the initial position is located in the third counter bore 73, an annular space is formed between the first stepped post 41 and the third counter bore 73, the pressure gas located in the third counter bore 73 reaches the other side through the annular space, then enters the other arc groove 72 through each of the flow dividing holes 75 in the other arc groove 72, thereafter, the pressure gas located in the other arc groove 72 enters the second submerged air passage 106 through the other air vent 11, and finally is discharged outwards, and thus the valve at this time is in a passage state.
The spanner 3 is shifted to rotate the root part of the spanner, so that the valve rod 4 is pressed downwards to move downwards along the guide sleeve 6 and compress the spring 5, the lower end of the valve rod 4 gradually stretches into the third counter bore 73, and as the outer wall of the valve rod 4 is mutually attached to the inner wall of the third counter bore 73, when the lower end of the valve rod 4 moves below each flow dividing hole 75, the opening of the inner end of each flow dividing hole 75 is sealed by the outer wall of the valve rod 4, so that pressure gas cannot enter into the third counter bore 73, and the gas path is cut off; the pressure gas that would otherwise remain in the third counterbore 73 is compressed into the bottom of the third counterbore 73 and the through hole 74, and then enters the exhaust counterbore 43, exits the exhaust hole 44, and is exhausted outward through the exhaust groove 65.
When the spanner 3 is reversely shifted to enable the root part of the spanner to leave the upper end of the valve rod 4, the valve rod 4 moves upwards under the action of the rebound force of the spring 5, and when the lower end of the valve rod 4 moves above each flow dividing hole 75, the pressure gas can smoothly enter the third counter bore 73, so that the passage of the gas flow is restored; if the air inlet pipe and the air outlet pipe are interchanged with the two connected pneumatic quick connectors, the same effect can be achieved according to the same principle, and the two pneumatic quick connectors are not separated.
The utility model can exchange the air inlet direction and the air outlet direction of the pressure air, so that the air inlet pipe and the air outlet pipe can be quickly and randomly connected when in use, the direction confirmation is not needed, and the use is convenient; while simplifying the internal structure of the valve block 1 to facilitate the processing of the valve block 1.
