Described spool is positioned at go back to glue position, and described second link slot is communicated with into Jiao Kou and the first communication port, the second communication port;
Described spool is positioned at and adds glue position, and described first link slot is communicated with into Jiao Kou and the first communication port, and described second link slot is communicated with gum outlet and the second communication port.
The beneficial effects of the utility model are, realize the flow driving to inertia glue self dexterously using inertia glue as pressure medium; Glue amount is accurately easy to adjust, and valve working is reliable.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is spool when being positioned at go back to glue position, the inner structure schematic diagram of device;
Fig. 2 is that spool is positioned at when adding glue position, the inner structure schematic diagram of device.
Detailed description of the invention
See accompanying drawing, reflect a kind of concrete structure of the present utility model, the described valve system for vacuum test tube inertia glue enhancing perfusion comprises dosing unit 1 and valve unit 2, described dosing unit 1 is divided into the adjustment chamber 102 of top and the closed chamber of below, closed chamber device piston 105, piston 105 upper surface device piston rod 103, piston rod 103 upper end extend out in described adjustment chamber 102, piston rod 103 is rectified the bottom to the adjusting screw(rod) 101 of top; Described closed chamber is divided into epicoele 104 and cavity of resorption 106 by piston 105, and epicoele 104 top end face is provided with upper shed 108, and cavity of resorption 106 bottom face is provided with under shed 107;
Described valve unit 2 comprises valve seat 211 and spool 202, the center of the affixed auxiliary piston 201 in spool 202 top, auxiliary piston 201 device is in secondary closed chamber, secondary closed chamber is divided into upper and lower two chambeies by auxiliary piston, and epicoele pore 203 is communicated with air compression plant (not shown in FIG.) control spool about 202 with cavity of resorption pore 204 respectively by air valve and moves linearly.
Spool 202 is provided with the first link slot 205 and the second link slot 208, on valve seat 211 correspondence be provided with gum outlet 207, first communication port 210, second communication port 209, Bonding pressure pump (not shown in FIG.) enter glue mouth 206, first communication port 210 is communicated with described upper shed 108, second communication port 209 and is communicated with described under shed 107.
When spool 202 is positioned at go back to glue position (as shown in Figure 1), the second link slot 208 is communicated with into glue mouth 206 and the first communication port 210, second communication port 209.The inertia glue with pressure enters epicoele 104 and the cavity of resorption 106 of closed chamber respectively by upper shed 108 and under shed 107, the piston rod 103 due to piston 105 upper surface device, its area of thrust surface are less than lower surface, piston 105 moves until piston rod 103 tip contact adjusting screw(rod) 101 lower end, make to be full of inertia glue in cavity of resorption 106.The upper-lower position of adjustment adjusting screw(rod) 101, can regulate glue amount.
Then in the epicoele of secondary closed chamber, pressurized air is passed into by epicoele pore 203, make auxiliary piston 201 be with movable valve plug 202 move down into described in add glue position (as shown in Figure 2): now the first link slot 205 is communicated with into glue mouth 206 and the first communication port 210, and described second link slot 208 is communicated with gum outlet 207 and the second communication port 209; Because the cavity of resorption 106 of now closed chamber is no longer communicated with into glue mouth 206, piston 105 lower surface loses pressure support ventilation, and upper surface with enter glue mouth 206 and be communicated with, piston 105 moves down under pressure, and the inertia glue in cavity of resorption 106 is sequentially delivered to gum outlet 207 by under shed 107, second communication port 209, second link slot 208.Gum outlet 207 is communicated with filling mechanism (not shown in FIG.), is sent in vacuum test tube by inertia glue.
The above-mentioned implementation that the utility model describes is only to clearly the technical solution of the utility model is described, and can not be interpreted as and make any restriction to the utility model.The utility model has known multiple alternative or distortion in the art, under the prerequisite not departing from the utility model essential meaning, all falls into protection domain of the present utility model.
