It rises, seals the protrusion of the rubber seal on slide plate 112 114 and be separated with channel end surface 113, valve fully opens.Middle valve rod at this time
23 top is contacted with drive pin 215, and the upper roller sliding slot 27 on upper valve rod 22 is just installed with the upper roller on middle valve rod 23
Hole 28 is aligned, and the rising of 215 centering valve rod 23 of drive pin is limited so that middle valve rod 23 is no longer along relative to upper valve rod 22
It is axial to rise, under the rotating tendency for driving upper valve rod 22 in driving motor, i.e., under the action of circumferential driving force, upper roller 213
It can be skidded off from the roller sliding slot 212 in roller sleeve 211 and be pressed into upper roller sliding slot 27 and upper roller mounting hole 28
In so that upper valve rod 22 and the connection locking of middle valve rod 23, at this point, upper valve rod 22, middle valve rod 23 and 24 three of lower valve rod are locked in
Together.
Driving motor drives upper valve rod 22 to continue to rotate, and drives upper valve rod 22, middle valve rod 23 and 24 three of lower valve rod together
Rotation, guide pin 217 in operator 2 move to the slot bottom that the other end enters the second vertical slot 2163 from one end of translot 2162,
Cock 16 in main valve 1 is rotated with dynamic sealing slide plate 112, and another on off state is switched to from a kind of on off state.Lower roller
214 with the lower alignment of the roller sliding slot 212 of roller sleeve 211, continue to move, the rotation of upper valve rod 22 driven in driving motor
Under trend, i.e., under the action of circumferential driving force, lower roller 214, which is understood in the therefrom lower roller sliding slot 29 of valve rod 23, to be skidded off and is squeezed
It is pressed into the lower part of lower roller mounting hole 210 and roller sliding slot 212 so that middle valve rod 23 and lower valve rod 24 are detached from, lower valve rod
24 lock together with roller sleeve 211, at this point, both upper valve rod 22 and middle valve rod 23 lock together.
Driving motor drives upper valve rod 22 to continue to rotate, and driving motor drives upper valve rod 22 and middle valve rod 23 to rotate together,
Be driven by the second motion thread 26, due to the thread rotary orientation of the second motion thread 26 and the first motion thread 25 on the contrary, so
Lower valve rod 24 moves downward decline relative to middle valve rod 23, and guide pin 217 also moves therewith relative to U-type groove 216, works as operator
The slot bottom of guide pin 217 from the second vertical slot 2163 in 2 moves to groove top, and the cock 16 in main valve 1 drops to lower limit position,
So that sealing slide plate 112 contacts sealing with channel end surface 113.Similarly, under the action end state of aforesaid operations device 2, driving
Motor drives upper valve rod 22 to rotate, and guide pin 217 reversely walks a same stroke in U-type groove 216, and middle valve rod 23 drops to
Initial position, entire two tubing type plug valves restore to original state.
Pass through aforesaid operations device operating principle, when driving motor inverts, the control operation main valve 1 of operator 2, you can realize
The promotion of the cock 16 of two tubing type plug valves, the valve event for being rotated by 90 ° and descending again means of press seals counterclockwise；Work as driving motor
During reversion, the promotion for realizing cock 16, the valve event for rotating clockwise 90 ° and descending means of press seals again.
