Abstract
The utility model discloses a kind of continuous flow three-way switch valve, comprise valve body and be arranged at upper cover and the lower cover at the upper and lower two ends of described valve body, in valve body, be provided with rotating shaft, shaft bearing is connected between described upper cover and lower cover, in rotating shaft, be fixed with cam by key, also comprise the He You fluid passage, left fluid passage that is symmetricly set in valve body both sides, be arranged at total fluid passage of described valve body front side, the double pilot hole that does respectively in He You fluid passage, left fluid passage, in pilot hole, be provided with spool, spool outer side surface is provided with seal ring.Solve in prior art and become afterwards because liquid communication aperture in valve commutation process first diminishes the large problem of pressure difference causing greatly, in addition, this continuous flow three-way switch valve structure is ingenious, having changed existing three-way switch valve can not be in the situation of working site maintenance, and accessory is also easy to buy, simple in structure, easy to operate, be easy to promote.
Description
Technical field
The utility model belongs to mechanical-hydraulic technical field, is specifically related to a kind of continuous flow three-way switch valve.
Background technique
Three-way switch valve turns to switching for two elements that use in parallel, as the duplex filter in lubrication system, and duplex cooler.Three-way switch valve turns to switching for two elements that use in parallel, as the duplex filter in lubrication system, and duplex cooler.On market, existing three-way switch valve is due to the reason of spool self structure, in the time of valve core rotation, can produce very large resistance, add in spool handoff procedure, the bore of circulation is first to diminish becoming large, valve inside and outside differential pressure is changed also greatly, the resistance that has increased equally valve commutation, when this just makes valve commutation, valve inside and outside differential pressure is that great changes have taken place, this pressure surge meeting has a huge impact equipment.
Model utility content
The purpose of this utility model is to provide a kind of continuous flow three-way switch valve, has solved the excessive and hydrodynamic pressure of existing continuous flow three-way switch valve resistance in the commutation process large problem that fluctuates.
The technological scheme that the utility model adopts is: a kind of continuous flow three-way switch valve, comprise valve body and be arranged at upper cover and the lower cover at the upper and lower two ends of described valve body, in valve body, be provided with rotating shaft, shaft bearing is connected between described upper cover and lower cover, in rotating shaft, be fixed with cam by key, also comprise the He You fluid passage, left fluid passage that is symmetricly set in valve body both sides, be arranged at total fluid passage of described valve body front side, the double pilot hole that does respectively in He You fluid passage, left fluid passage, in pilot hole, be provided with spool, spool outer side surface is provided with seal ring.
Feature of the present utility model is also,
The top that described upper cover is extended in rotating shaft is provided with turning handle.
Left and right fluid passage, pilot hole and spool are coaxial setting.
Seal ring is U-shaped.
The beneficial effects of the utility model are: continuous flow three-way switch valve, spool is in rotation process, when a side liquid passage is closed gradually, open gradually opposite side fluid passage, level and smooth continuous switching like this, reduce the variation of spool inside and outside differential pressure, can not have a huge impact equipment, in addition due to the mild like this transport pipe that opens or closes, in the time switching, too large pressure does not go prevention to open or close valve, the surface of contact of spool and valve body is taked gap-contact, thereby minimizing frictional force, be easy to flow switch, this continuous flow three-way switch valve spool adopts U-shaped seal ring, good sealing effect, can leakage of oil in the time that pressure difference is larger yet.
Brief description of the drawings
Fig. 1 is the plan view of the utility model continuous flow three-way switch valve;
Fig. 2 is the sectional view of the utility model continuous flow three-way switch valve.
In figure, 1. valve body, 2. upper cover, 3. lower cover, 4. rotating shaft, 5. turning handle, 6. key, 7. cam, 8. left fluid passage, 9. right fluid passage, 10. total fluid passage, 11. pilot holes, 12. spools, 13. seal rings.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of the utility model continuous flow three-way switch valve as depicted in figs. 1 and 2, comprise valve body 1 and be arranged at upper cover 2 and the lower cover 3 at described valve body two ends Shang Xia 1, in valve body 1, be provided with rotating shaft 4, rotating shaft 4 bearings are connected between upper cover 2 and lower cover 3, in rotating shaft 4, be fixed with cam 7 by key 6, also comprise the left fluid passage 8 and the right fluid passage 9 that are symmetricly set in valve body 1 both sides, be arranged at total fluid passage 10 of valve body 1 front side, the interior double pilot hole 11 that does respectively in left fluid passage 8 and right fluid passage 9, in pilot hole 11, be provided with spool 12, spool 12 outer side surfaces are provided with seal ring 13.
When use, in the time that continuous flow three-way switch valve flows to switching, turning handle 5 drives rotating shaft 4 to rotate, rotating shaft 4 is connected cam 7 and is with moving cam 7 to rotate by key 6, the final spool 12 that promotes carries out linear reciprocating motion, to rotatablely move and convert linear reciprocating motion to by cam mechanism, open or close left and right fluid passage 8,9 with this.
A kind of continuous flow three-way switch valve of the utility model, solve in prior art and become afterwards because liquid communication aperture in valve commutation process first diminishes the large problem of pressure difference causing greatly, reduce the impact that the fluctuation of pressure causes equipment, in addition, this continuous flow three-way switch valve structure is ingenious, and having changed existing three-way switch valve can not be in the situation of working site maintenance, and accessory is also easy to buy, simple in structure, easy to operate, be easy to promote.
