Embodiment
See also Fig. 1 to shown in Figure 4, the utility model relates to a kind of pneumatic valve joint, and it comprises:
See also shown in Fig. 4,5, when knob 2 when a direction is rotated, perforation 22 on its upper valve rod 21 just can be staggered with the main channel 14 of body 1 gradually, when the perforation 22 and the alternating quantity of main channel 14 heal when big (bore a hole 22 littler) with the involutory degree of main channel 14, then flow is just little, otherwise then flow is bigger, and when perforation 22 and main channel 14 are staggered fully, just forms the state of closing and not circulating; Otherwise, when the complete involutory state of perforation 22 and 14 one-tenth of main channel, then be peak rate of flow, can reach the purpose of control flow rate by this structure.
See also shown in Fig. 3,6, when pushing press button 5, but these press button 5 interlocks are controlled valve rod 4 and it are inwardly contracted and move a segment distance, thereby the last O type ring 42 that makes control valve rod 4 one ends moves apart the chute 34 of positioning block 3, simultaneously press button 5 is spring 6 compressive strains, causes the air-flow in the main channel 14 of body 1 to be blown out by secondary conduit 37 through chute 34 by second tank 16; And when decontroling press button 5, then control valve rod 4 just can be subjected to the elastic-restoring force effect of spring 6 and outwards withdraw from, make O type ring 42 return back to the opening of chute 34 once more, from face chute 34 is sealed, reach the function of use of air pressure gun with this.
See also shown in Figure 7, when press button 5 is pressed down, and by 53 screw locks of the internal thread on the press button 5 on the outside thread 32 of positioning block 3 time, the last O type ring 42 of then controlling valve rod 4 just forms the permanent state that breaks away from chute 34, at this moment, therefore secondary relatively conduit 37 also can present the state of normal open, and so it just can be used as the tee union use.
