Embodiment
Referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5, the location resetting structure of hand-operated direction valve, hand-operated direction valve comprises manual reverse of direction mechanism 1, valve body 3, spool 4, rear end cover 17, bonnet 9 and location resetting-mechanism 7, the left part of spool 4 is connected with manual reverse of direction mechanism 1, it is characterized in that the right part of spool 4 is set to locate resetting-mechanism 7; Described location resetting-mechanism 7 is positioned at rear end cover 17 and the bonnet 9 formed cavitys that set gradually from left to right; Described location resetting-mechanism 7 comprises Returnning spring 10, spring seat, retaining spring 12, pressure pad 14, place kick group and setting sleeve 8; Spring seat comprises left spring seat 19 and right spring seat 20, and left spring seat 19 and right spring seat 20 all are sheathed on the spool 4 and can endwisely slip along spool 4 outer circumferential faces, and Returnning spring 10 is located between left spring seat 19 and the right spring seat 20; Be provided with retaining spring 12, place kick group in the cavity of establishing in spool 4 right parts from left to right successively; The setting sleeve 8 that is sheathed on spool 4 right parts is positioned at the cavity that bonnet forms and also can slides at this cavity, and the inner peripheral surface of setting sleeve 8 is provided with ring-shaped step 18.The cavity of establishing in described spool 4 right parts is step-like cavity, and the diameter of cavity increases from left to right successively, and retaining spring 12 is located in the cavity part of diameter minimum; The place kick group comprises a big place kick 15 and a plurality of little place kick 16, and the right-hand member of retaining spring 12 connects with big place kick 15; Big place kick 15 is positioned at the bigger cavity part of diameter, and also some extend out to the cavity part of diameter maximum to the right; Be provided with a plurality of circular holes on the wall of the cavity part of the diameter maximum of spool 4, be provided with a little place kick 16 in each circular hole, the sphere of little place kick 16 is tangent with the sphere of big place kick 15.Described pressure pad 14 is sheathed on the spool 4, and pressure pad 14 is clipped between rear end cover 17 and the bonnet 9.Described left spring seat 19 and right spring seat 20 are step-like, also are provided with the step that matches with spring seat on the periphery of spool 4 parts of sheathed spring seat.The inner peripheral surface of described setting sleeve 8 is provided with twice ring-shaped step 18.Described big place kick 15 and little place kick 16 are steel ball.
Among Fig. 2, spool 4 is in meta, promptly remains static, and this moment, Returnning spring and retaining spring all were in original state.
As shown in Figure 3, when manual reverse of direction mechanism 1 manipulation spool 4 was pulled out left, spool 4 drove right spring seats 20 and locating column 13 and big or small place kick and is moved to the left together.Setting sleeve 8 is slidably in bonnet 9 the insides, has only after setting sleeve 8 abuts to pressure pad 14 and just can not move again.After the little place kick 16 in the locating column 13 arrived to the ring-shaped step 18 in setting sleeve 8 left sides, drive setting sleeve 8 was moved to the left until setting sleeve and abuts to pressure pad 14.Because stopping of ring-shaped step 18, at this moment little place kick 16 can't drive setting sleeve 8 again and continue to slide, and manual reverse of direction mechanism is subjected to certain resistance, and at this moment manually commutation left puts in place.After this operation has two kinds of situations:
If 1 at this moment the staff unclamp manual reverse of direction mechanism 1, spool 4 can be got back to meta automatically under the active force of Returnning spring 10.
2, if at this moment the staff continues firmly to spur spool 4 left, spool 4 drives little place kick 16 and is moved to the left, after little place kick 16 is subjected to the extruding of ring-shaped step 18 in setting sleeve 8 left sides, little place kick 16 will be pushed big place kick 15, big place kick 15 compression set springs 12, at this moment little place kick 16 is with regard to the retraction circular hole, spool 4 drives little place kick 16 and crosses ring-shaped step 18, then little place kick 16 is under the effect of retaining spring 12, again eject circular hole and be connected on the left side one side of ring-shaped step 18, this moment is if continue to spur spool 4 left, then right spring seat 20 will connect with left spring seat 19, spool 4 can't continue to be moved to the left again, and promptly spool 4 is in the limit position (as shown in Figure 4) of high order end.If the staff unclamps manual reverse of direction mechanism 1 at this moment, right spring seat 20 is under the effect of Returnning spring 10, drive spool 4, place kick group and setting sleeve 8 and move right together, arrive on the bonnet 9 up to setting sleeve 8, little place kick 16 simultaneously is connected on the left side one side of ring-shaped step 18.Because the resistance of 18 pairs of little place kick 16 of ring-shaped step is greater than the thrust of Returnning spring 10, thereby little place kick 16 can't cross the ring-shaped step 18 of setting sleeve 8 automatically, and this moment, spool 4 was fixed on the position of commutation left (as shown in Figure 5).If make spool 4 return to meta, need the staff to apply external force in manual reverse of direction mechanism 1, make little place kick 16 cross ring-shaped step 18 to the right, spool 4 could return to meta shown in Figure 2 under the effect of Returnning spring 10 then.
When manual reverse of direction mechanism 1 manipulation spool 4 advances to the right, can realize the location that spool 4 commutates to the right, the course of action of each parts is similar to commutation left.
In the utility model, owing to adopt spring seat, Returnning spring as resetting means, adopt place kick group and inside to be provided with the setting sleeve of step as positioning device, make the spool of hand-operated direction valve in certain stroke, have auto-reset function, and has locating function at diverse location, and easy to operate, operating handle is good.Location of the present utility model resetting structure is parts such as spring seat, Returnning spring, place kick group and setting sleeve to be set by the spool end at existing hand-operated direction valve realize, and is little to the structural change of selector valve, the low and easy realization of reforming cost.The utility model adopts spring seat, Returnning spring, place kick group, component such as setting sleeve movably, makes selector valve have locating function and auto-reset function concurrently, and have easy to operate, operating handle good, reforming cost is low and advantage such as easy realization.
The utility model is particularly useful for hand-operated direction valve.
