The working principle of the scheme is as follows:
the first branch pipe is used for communicating a liquid storage tank containing liquid injection materials, the second branch pipe is used for communicating a negative pressure suction device, a flushing suction head on the main pipe is used for injecting and sucking out the materials, a switching valve in the switching cavity is used for realizing the communication between the first branch pipe and the second branch pipe and the main pipe respectively, after the first branch pipe is communicated with the main pipe, the injection materials enter the switching cavity through the first branch pipe and then enter the main pipe, and the injection materials are injected into breasts through the flushing suction head at the free end of the main pipe. When the amount of the injection material discharged from the liquid storage tank meets the requirement, the first valve is closed, part of the injection material still remains in the first branch pipe, the part of the liquid continuously flows and then enters the switching cavity, the control valve rotates forwards under the action of the gravity and the impact force of the liquid in the switching cavity, when the liquid in the first branch pipe completely flows out, the force applied to the control valve by the liquid disappears, the control valve is in a vacant state, because the gravity moment from the first control part to the control shaft in the control valve is different from the gravity moment from the second control part to the control shaft, the control valve has reverse torque, the control valve rotates reversely, namely the control shaft, the first control part and the second control part rotate reversely, the control shaft drives the switching shaft to rotate through the transmission mechanism, the switching block fixed on the switching shaft rotates around the switching shaft, and the switching block blocks the first branch pipe, The second branch pipe is exposed, so that the first branch pipe and the second branch pipe are respectively communicated with the main pipe.
This scheme of adoption can reach following technological effect:
1. through first branch pipe and the intercommunication of being responsible for, can reach the effect of injection liquid, through second branch pipe and the intercommunication of being responsible for, can reach the effect of attracting liquid, have injection simultaneously and attract two kinds of functions, inject with attract with traditional and need two sets of equipment to compare, saved the trouble of changing equipment on the one hand, on the other hand can also reduce because frequently change the probability of cross infection that equipment brought.
2. The switching of the first branch pipe and the second branch pipe can be realized by rotating the switching valve, and the rotation of the switching valve is realized automatically by the control valve without manual switching.
3. After the injection liquid amount meets the requirement, the liquid remained in the first branch pipe continues flowing, and the liquid residue in the first branch pipe is avoided.
4. After all the liquid reserved in the first branch pipe flows out, namely the control valve is in an idle state, the control valve can automatically drive the control valve to rotate through the difference between the gravity moments from the first control part and the second control part to the control shaft, and an external power mechanism is not needed for driving.
Further, drive mechanism includes the belt, and the belt winding is on control shaft and switching shaft, the control shaft cover is equipped with rotates the cover, and is equipped with one-way bearing between control shaft and the rotation cover, first control division and second control division respectively with rotate cover outer fringe fixed connection. The transmission of the control shaft and the switching shaft can be simply and effectively realized through the belt.
Furthermore, a mounting seat is fixed in the switching cavity, the mounting seat is provided with a slope, and the control shaft is rotatably connected to the mounting seat. The liquid flowing down the first branch flows on a slope, giving a pressure to the first control part of the control valve, so that the control valve rotates forward.
Further, the outer edge of the switching block is in an arc shape matched with the inner wall of the switching cavity. By adopting the structure, the switching check block can always keep attached to the inner wall of the switching cavity when rotating, and the first branch pipe is prevented from being communicated with the second branch pipe.
Furthermore, a flow regulating valve is arranged on the first branch pipe. The flow regulating valve can regulate the flow rate of the injection liquid in the first branch pipe.
Furthermore, a chuck is arranged on the second branch pipe. The clamping head can realize the clamping of the second branch pipe.
