In addition, in order to ensure the sealing of this device, on the first groove 160 and the second groove 170, be separately installed with seal ring 180 and Sealing shield ring 190(referring to Fig. 1).
Sealing shield ring 190, adopts not cut forms, is not easy like this to drop and damage, thereby has ensured sealing.
Referring to Fig. 1, one end of spool 200 is removable connection of inner chamber 130 with valve pocket 100 through spring groove 110 and spring 110 successively.
Referring to Fig. 3, in addition, can, in the interior movement of the inner chamber of valve pocket 100 130, on the other end of spool 200, be provided with boss 210 for the ease of spool 200, boss 210 is connected with spring 110, like this, spool 200 just can be supported on valve pocket 100 by spring 110, in the time that spool 200 is received ambient pressure, spool 200 can promote spring 110 and move down, when the ambient pressure being subject to when spool 200 disappears, spring 110 can, for spool 200 provides rebounding force, move up thereby promote spool 200 again.
When spool 200 is assigned in valve pocket 100, control the connectedness between the first hydraulic fluid port 120, the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150 on valve pocket 100 for the ease of spool 200, be provided with symmetrical the first shoulder 220, the second shoulder 230 and the 3rd shoulder 240 in the both sides of spool.
The first shoulder 220, the second shoulder 230 and the 3rd shoulder 240 can also do leading role for the hydraulic fluid port in valve pocket 100.
The first shoulder 220, the second shoulder 230 and the 3rd shoulder 240 are connected with the chamber wall of valve pocket 100 inner chambers 130 respectively, like this when spool 200 is interior when mobile at valve pocket 100, when the first shoulder 220 is between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, at this moment the first shoulder 220 can cut off the connectedness between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, and at this moment the 3rd hydraulic fluid port 150 can only be communicated with the first hydraulic fluid port 120;
Spool 200 moves in the interior continuation of valve pocket 100, and in the time that the first shoulder 220 moves to the 3rd hydraulic fluid port 150 bottom, at this moment, the first shoulder 220 can cut off the connectedness between the 3rd hydraulic fluid port 150 and the first hydraulic fluid port 120, and at this moment, the 3rd hydraulic fluid port can only be communicated with the second hydraulic fluid port 140.
In spool 200, offer the first through hole 250, upwards be provided with the second through hole 260 and third through-hole 270 in the footpath of spool 200, third through-hole 270 is communicated with the first through hole 250 and the second through hole 260 respectively, the oil content that flows into the second through hole 260 can not guided to electromagnet place by the first through hole 250 and flow in spring groove 110 by third through-hole 270 like this, so not only can lower the temperature to electromagnet, but also can pass through spring groove 110 drainings, thereby can make spool 200 commutate smoothly.
In addition, more reliable in order to commutate, can play guide functions, on one end of spool 200, be provided with the conical surface 280.
Referring to Fig. 1, for the ease of controlling the movement of spool 200 in valve pocket 100, a kind of plug-in type electromagnetism selector valve that the utility model provides also comprises an electromagnet 300.
Electromagnet 300, its one end is connected with spring groove 110, and the end face that electromagnet 300 is connected with spring groove 110 is provided with resettlement groove 310, resettlement groove 310 can be connected with the other end of spool 200, and electromagnet 300 can promote spool 200 and moves down in valve pocket 100 like this.
Electromagnet 300 is as follows with coordinating of spool 200:
In the time that electromagnet 300 is switched on, electromagnet 300 can move down, and moves down in valve pocket 100 thereby promote spool 200, and in the time of electromagnet 300 no electric circuit, electromagnet 300 stops mobile, and spring 111 can go back spool 200 bounce-backs.
Between electromagnet 300 and spring groove 110, can be threaded connection, in order to strengthen the sealing between electromagnet 300 and spring groove 110, between electromagnet 300 and spring groove 110, be provided with seal ring 320.
Specific works process of the present utility model below:
Referring to Fig. 1, first one end of spool 200 is assigned in valve pocket 100 through spring groove 110 and spring 110 successively, at this moment because spool 200 is supporting, the first shoulder 220 on spool 200 is just between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, at this moment the first shoulder 220 can cut off the connectedness between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, and at this moment the 3rd hydraulic fluid port 150 can only be communicated with the first hydraulic fluid port 120;
Then electromagnet 300 is connected with spring groove 110, then electromagnet 300 is switched on, at this moment electromagnet 300 can move down by promotion spool 200 in valve pocket 100, at this moment the first shoulder 220 can move to the 3rd hydraulic fluid port 150 bottoms, at this moment, the first shoulder 220 can cut off the connectedness between the 3rd hydraulic fluid port 150 and the first hydraulic fluid port 120, and at this moment, the 3rd hydraulic fluid port can only be communicated with the second hydraulic fluid port 140.
When electromagnet 300 stops energising, at this moment spring 110 can head on spool 200 and moves up in valve pocket 100, at this moment the first shoulder 220 on spool 200 is got back to again between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, at this moment the first shoulder 220 can cut off the connectedness between the second hydraulic fluid port 140 and the 3rd hydraulic fluid port 150, and at this moment the 3rd hydraulic fluid port 150 can only be communicated with the first hydraulic fluid port 120.
