Embodiment
Extremely shown in Figure 6 as Fig. 1, three-way valve of the present invention comprises valve body 1, valve pocket 3 and spool 2, valve body 1 has a cylindrical cavity 11, be respectively arranged with three port ones 2 that communicate with cavity 11 on three outer surfaces of valve body 1,13 and 14, each port is provided with pipe joint 19,110 and 111, pipe joint 19 is used to import cleaning solution, pipe joint 110 is used to import marking ink, pipe joint 111 is used to export cleaning solution or marking ink, port one 2 and port one 3 are positioned on the same straight line that passes cavity 11 centers, the center line of port one 4 pass equally cavity center line and with port one 2,13 center line is perpendicular.Port one 2 is connected with extraneous ink supply pipeline, port one 3 is connected with print head China ink road, port one 4 is connected with the cleaning solution supply line.Cylindric spool 2 comprises flange 21, core body 22 and handle 23, spool 2 is inserted in the cavity 11 on the valve body 1, and, utilize handle 23 operable valve cores 2 in valve body 1, to rotate by the flange 21 of one end setting and rotatable being installed on the valve body 1 of interface arrangment of the other end setting thereof.
Between valve body 1 and spool 2, be provided with position structure, this position structure comprises on the flange 21 blind hole 15 and the locating column 18 that is provided with on the recess 213 that is provided with on the breach that is provided with, flange 21 lower surfaces, the valve body 1, wherein be placed with spring 16 in the blind hole 15, spring 16 upper ends are provided with ball 17.Breach is the semi-circular breach with flange 21 concentrics, and itself and locating column 18 are used, spool 2 turns to after breach one end is pressed over locating column 18 contact, spool 2 just can not be rotated further, thereby can realize qualification to two circumferential limit circumferential positions of spool 2, one breach end 212 of breach be positioned at handle 23 under, play visually the effect of location like this.Recess 213 is used with hole 15 interior spring 16 and the balls 17 that are provided with, after spool 2 is inserted on the valve body 1 ball 17 elastic reaction by spring 16 all the time roof pressure on flange 21 lower surfaces, rotational valve core 2, after ball 17 enters recess 213, can realize qualification to a middle circumferential position of spool 2.
Between valve body 1 and spool 2, also be provided with valve pocket 3, valve pocket 3 is fixedly installed on the valve body 1, it is provided with three open-works 31 that communicate one by one with port one 2,13,14 respectively, the material of valve pocket 3 is a teflon, this material has certain elasticity, and friction factor is little, thereby after valve pocket 3 is set, both guaranteed good seal between valve pocket 3 and the spool 2, guaranteed again that spool 2 rotated flexibly in valve body 1.
During work, pulling handle 23, after breach end 212 is resisted against locating column 18, is that three ports all are in closed state on the valve body 1, this moment ink supply pipeline and the equal access failure print head of detergent line black road, print head is in the state of quitting work; Pull handle 23, after ball 17 entered recess 213, port one 2 and port one 3 on the valve body 1 were connected by the liquid chunnel on the spool 2, and at this moment the ink supply pipeline can carry out normal printing by the black road ink supply of three-way valve to print head; Pull handle 23, when breach end 214 behind locating column 18, port one 4 and port one 3 on the valve body 1 are connected by the liquid chunnel on the spool 2, the cleaning solution supply line is access in the black road of print head, at this moment can carry out cleaning operation to print head.
The above-mentioned position structure that constitutes by breach and locating column 18, because of two circumferential positions that utilize locating column 18 to match with the two ends of breach respectively to spool 2 limit, therefore can avoid occurring spool 2 and cross the situation that its circumferential limit position continues rotation, thereby can prevent that the ink supply pipeline is connected with the cleaning solution supply line, guarantee the safety of ink feeding system.
Valve body 1 also can be arranged to like this with the position structure between the spool 2: comprise three recesses that are provided with on hole that is provided with on the valve body 1 and flange 21 lower surfaces that match with this hole, three recesses are along circumferentially being provided with at interval, be provided with spring in the hole on the valve body and by the ball of this spring pretension, rotary spool 2, when ball respectively with flange 21 on different recess when matching, can realize qualification to three kinds of circumferential positions of spool.
