Abstract
The utility model discloses a reverse direction valve, and a valve core of the reverse direction valve moves in same direction with water flow when seals the sealing steps, therefore requiring small force. At the same time, when the reverse direction valve is closed, the valve core is forced by the water flow so as to keep a tight sealing state. Also, the reverse direction valve can be opened or closed only by starting a servo motor, and the operation is quite simple.
Description
Technical field
The present invention relates to valve technology field, especially relate to a kind of reversing valve.
Background technique
Along with the increase of valve applications scope, the size of many valves increases increasingly, thereby the pressure that the spool of this valve is subject to is very big.Because the spool of most valves is in face of the direction of current and throttle down, thereby cause closing of many valves to need great strength, and be difficult for closing tight, meanwhile, operate also comparatively loaded down with trivial details.
Summary of the invention
The object of this invention is to provide a kind of reversing valve, it is comparatively simple that it has the operation of throttle down, and required strength is less, closes very tight feature.
The technical solution adopted in the present invention is: reversing valve, and described reversing valve comprises:
---be positioned at the intake pipe of right part, this intake pipe outer surface right-hand member is provided with right adpting flange, outer surface left end is provided with right step, meanwhile, in the inner chamber of this intake pipe, is provided with chute, the right-hand member of this chute connects the right side to this intake pipe, and the inner chamber left end of this intake pipe is provided with sealed step;
---spool, the left end axle center place of this spool is fixed with leading screw, and the left end outer rim of this spool is compatible with sealing step, meanwhile, the slide block that the outer rim of this spool is provided with and this chute matches;
---be positioned at the outlet pipe of left part, the outer surface left end of this outlet pipe is provided with left adpting flange, outer surface right-hand member is provided with left step;
---link, the right groove that the right-hand member of this link is provided with and this right step matches, and the right-hand member of this link is fixed with right cover plate by screw, this right cover plate is limited in this right step in this right groove, the left groove that the left end of this link is provided with and this left step matches, and the left end of this link is fixed with left cover by screw, this left cover is limited in this left step in this left groove, simultaneously, this link middle part is provided with permeable hole, and the axle center place of this link is provided with and the screw of this leading screw threaded; And
The outside interference fit of this link be arranged with gear ring, this gear ring is engaged in a gear, this gear is connected to one speed reducer, this retarder is connected with motor.
Described motor is actuating motor.
The advantage that the present invention has is: operate comparatively simply, and required strength is less, closes very tight.When the spool of reversing valve of the present invention seals sealing step, movement direction is same as the direction of current, thereby required strength is less.Meanwhile, at this reversing valve, during in closed condition, this spool continues to be subject to the pressure of current, and this pressure has also been eliminated the mismatch error between leading screw and screw, thereby can remain very tight sealing state.And, only need to start this actuating motor, can realize the unlatching of this reversing valve or close, operate very simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of the decomposing state of the reversing valve of embodiments of the invention looks sectional view;
Fig. 2 is the right elevation of intake pipe of the present invention;
Fig. 3 is the right elevation of spool of the present invention.
In figure: 10, intake pipe, 11, right step, 12, chute, 13, sealed step, 14, right adpting flange; 20, spool, 21, leading screw, 22, slide block; 30, link, 31, right groove, 32, right cover plate, 33, left groove, 34, left cover, 35, permeable hole, 36, screw, 37, gear ring; 40, outlet pipe, 41, left step, 42, left adpting flange; 50, gear; 60, retarder; 70, motor.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: reversing valve, comprising: be positioned at intake pipe 10, the spool 20 of right part, the outlet pipe 40 that is positioned at left part, link 30.Concretely:
These intake pipe 10 outer surface right-hand members are provided with right adpting flange 14, outer surface left end is provided with right step 11.Meanwhile, be provided with chute 12 in the inner chamber of this intake pipe 10, the right-hand member of this chute 12 connects the right side to this intake pipe 10, and the inner chamber left end of this intake pipe 10 is provided with sealed step 13.
The left end axle center place of this spool 20 is fixed with leading screw 21, and the left end outer rim of this spool 20 is compatible with sealing step 13.That is, the left side of this spool 20 can with sealing step 13 close contacts, thereby realize closing of this reversing valve.Meanwhile, the slide block 22 that the outer rim of this spool 20 is provided with and this chute 12 matches.That is, this slide block 22 slides along this chute 12, thereby this spool 20 only can move left and right and cannot rotate.
The outer surface left end of this outlet pipe 40 is provided with left adpting flange 42, outer surface right-hand member is provided with left step 41.
The right groove 31 that the right-hand member of this link 30 is provided with and this right step 11 matches, and the right-hand member of this link 30 is fixed with right cover plate 32 by screw, and this right cover plate 32 is limited in this right step 11 in this right groove 31.Certainly these right step 11 and these right groove 31 Spielpassung., this link 30 can rotate with respect to this intake pipe 10 but the two cannot separate.The left groove 33 that the left end of this link 30 is provided with and this left step 41 matches, and the left end of this link 30 is fixed with left cover 34 by screw, and this left cover 34 is limited in this left step 41 in this left groove 33.Certainly these left step 41 and these right left groove 33 Spielpassung., this link 30 can rotate with respect to this outlet pipe 40 but the two cannot separate.Meanwhile, these link 30 middle parts are provided with permeable hole 35, and the axle center place of this link 30 is provided with and the screw 36 of these leading screw 21 threaded.
And, the outside interference fit of this link 30 be arranged with gear ring 37, this gear ring 37 is engaged in a gear 50, this gear 50 is connected to one speed reducer 60, this retarder 60 is connected with motor 70.The preferred actuating motor of this motor 70.
Course of action of the present invention: after this electric motor starting, this speed reducer action drives this gear rotation, thereby drives this link to be rotated with respect to this intake pipe and outlet pipe by this gear ring.Meanwhile, because this spool cannot rotate, thereby this leading screw can not rotate, and then, after the rotation of this nut, drives this spool travel by this leading screw, finally this spool near or away from sealing step, realized closing or opening of this reversing valve.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
