Further, the link position of described valve rod assembly and cylinder executive module is provided with support ring.
Further, described support ring is water-swellable sealing rod.
Further, described welding wire head is welded to connect and is structure as a whole with front valve shell, rear valve body respectively, then front valve shell, rear valve body, valve rod assembly and support ring are coupled together, support ring supports valve rod assembly, after the ventilation of cylinder executive module, drive valve rod assembly fore and aft motion, when valve rod assembly stretches out, material feeding mouth is communicated with discharge port.
Adopt the pneumatic three-position valve device of technique scheme, because valve body comprises front valve shell and the rear valve body being flexibly connected with front valve shell, the top of valve body is provided with material feeding mouth, sidepiece and the bottom of valve body are provided with discharge port, material feeding mouth docks with discharge port, described valve body is connected with a cylinder executive module, and the end of cylinder executive module is connected with a set of valve rod assembly, and valve rod assembly can be done fore and aft motion under the drive of cylinder executive module, the front portion of cylinder executive module is connected with rear valve body, the front portion of rear valve body is connected with front valve shell, on rear valve body and front valve shell, be all welded with welding wire head, cylinder executive module is connected with cylinder column, cylinder column is connected with valve rod assembly, the end of valve rod assembly is " H " type shape, the end of valve rod assembly is arranged in the connecting tube of material feeding mouth and discharge port, so drive valve rod assembly to move by cylinder executive module, effectively guaranteed the commutation of liquid (as dye solution) between two discharge ports, distance between front valve shell and rear valve body is short, and front valve shell and rear valve body are precision casting, effectively reduced liquid (as dye solution) retaining at front valve shell and rear valve body part.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pneumatic three-position valve device of the present invention.
Fig. 2 is the structure sectional view of the pneumatic three-position valve device of the present invention.
Embodiment
For making that structure characteristic of the present invention and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figures 1 and 2, a kind of pneumatic three-position valve device, comprises valve body 11, and valve body 11 comprises
Front valve shell 1 and the rear valve body 5 being flexibly connected with front valve shell 1, the top of valve body 11 is provided with material feeding mouth 9, the sidepiece of valve body 11 and bottom are provided with discharge port 10, material feeding mouth 9 docks with discharge port 10, valve body 11 is connected with a cylinder executive module 8, the end of cylinder executive module 8 is connected with a set of valve rod assembly 6, and valve rod assembly 6 can be done fore and aft motion under the drive of cylinder executive module 8, the front portion of cylinder executive module 8 is connected with rear valve body 5, the front portion of rear valve body 5 is connected with front valve shell 1, on rear valve body 5 and front valve shell 1, be all welded with welding wire head 2, cylinder executive module 8 is connected with cylinder column 12, cylinder column 12 is connected with valve rod assembly 6, the end of valve rod assembly 6 is " H " type shape, the end of valve rod assembly 6 is arranged in the connecting tube of material feeding mouth 9 and discharge port 10, on welding wire head 2, be connected with welding conehead 3 and nut 4, nut 4 is sleeved on the head of welding conehead 3, valve rod assembly 6 is provided with support ring 7 with the link position of cylinder executive module 8, support ring 7 is water-swellable sealing rod, welding wire head 2 respectively with front valve shell 1, rear valve body 5 is welded to connect and is structure as a whole, then by front valve shell 1, rear valve body 5, valve rod assembly 6 and support ring 7 couple together, support ring 7 supports valve rod assembly 6, after 8 ventilations of cylinder executive module, drive valve rod assembly 6 fore and aft motion, when valve rod assembly 6 stretches out, material feeding mouth 9 is communicated with discharge port 10.
