Abstract
The present invention relates to the technical field of a mechanical valve, particularly to a quantitative valve which can control the flow of fluids. The present invention comprises a valve body, a valve core, a handle, an inlet and an outlet. The present invention is characterized in that a gear is arranged on a rotary shaft of the valve core; a quantitative control mechanism is arranged on the valve body; the quantitative control mechanism is composed of a gear drive device and an impeller; the impeller is arranged on the outlet of the valve body; a gear is arranged on the rotary shaft of the impeller; the gear is matched with the gear drive device which is matched with the rotary shaft of the valve core. The present invention adopts the structure of the quantitative control mechanism arranged on the valve body; when the fluids flow out of the outlet of the valve body, the impeller rotates under the action of the fluids; the gear on the impeller pushes the gear drive device to work; when the fluids flowing out reach a certain quantity, the gear drive device can drive the rotary shaft of the valve core to rotate and the valve is automatically closed; thus, the present invention has the effect on preventing the fluids from flowing out.
Description
Technical field
The invention belongs to the machinery valve technical field, particularly relate to a kind of proportional valve that can control fluid flow.
Background technique
In background technique, the traditional mechanical valve mainly is by valve body, handle, spool, the inlet opening, compositions such as delivery outlet, handle is connected the upper end of spool mandrel, handle with sleeve can be realized the unlatching of valve body or close, thereby make the effect of a certain amount of fluid by valve, because the amount of the fluid that this valve flows out is to adopt manual operations control, behind the valve opening, must it could be closed by manual operations, in case forget throttle down, will cause the output of a large amount of fluids, not only wasted resource, but also can cause unnecessary property loss or security incident, therefore, developing a kind of valve that can quantitatively export fluid, is an approach that solves the conventional valves defective.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in design, compact structure, can control the mechanical type proportional valve of fluid output quantity.
The technical solution adopted in the present invention is achieved in that it comprises valve body, spool, handle, inlet opening and delivery outlet, it is characterized in that being equipped with on the described valve body quantitative control mechanism, this quantitative control mechanism is made of gear drive and impeller, described impeller is arranged in the valve body delivery outlet, the impeller gear is housed in the rotating shaft of impeller, this impeller gear matches with gear drive, described gear drive matches with the rotating shaft of spool, and described gear drive is by last bar gear, reply gear, the clockwork spring shaft gear, the ratchet actuation gear, ratchet, and valve core gear, spool driving gear, second transition gear, first transition gear, driven gear and clockwork spring constitute.
The present invention is owing to adopt the structure that quantitative control mechanism is installed on valve body, when fluid flows out the valve body delivery outlet, impeller rotates under the effect of fluid, then the gear on the impeller promotes gear drive work, when the fluid that flows out arrives when a certain amount of, gear drive can drive valve core shaft and rotate, and valve is closed automatically, reaches control fluid output effect.

Embodiment
The present invention includes valve body 5, spool 11, handle 1, inlet opening 9 and delivery outlet 7, in described spool 11 rotating shafts 26 valve core gear 25 is housed, on described valve body 5, quantitative control mechanism is housed, this quantitative control mechanism is made of gear drive and impeller 4, described impeller 4 is arranged in valve body 5 output channels 6, on the impeller shaft 3 of impeller 4 impeller gear 24 is housed, this impeller gear 24 matches with gear drive, and described gear drive matches with the valve core shaft 26 of spool 11; Described handle 1 rotating shaft 18 links with valve core shaft 26, bar gear 19 is housed on the arm pivot post 18, described gear drive by last bar gear 19, reply gear 13, clockwork spring shaft gear 28, ratchet actuation gear 12, ratchet 30 and valve core gear 25, spool driving gear 20, second transition gear 21, first transition gear 22, driven gear 14 and clockwork spring 29 and constitute, described clockwork spring 29 is arranged in the rotating shaft of clockwork spring shaft gear 28, and described ratchet 30 can match with answer gear 13; The described bar gear 19 of going up is meshed with answer gear 13, it is coaxial with driven gear 14 and clockwork spring shaft gear 28 to reply gear 13, when clockwork spring shaft gear 28 rotates, the valve core gear 25 that can drive on the valve core shaft 26 rotates, thereby make spool 11 be in opening state, when clockwork spring shaft gear 28 rotates, rotate with the ratchet actuation gear 12 of its engagement, this ratchet actuation gear 12 drives ratchet 30 and rotates, then make the fastener of ratchet 30 can be stuck in the bayonet socket 32 of answer 13, and clockwork spring 29 is tightened when clockwork spring shaft gear 28 rotates, when spool 11 is in opening state, fluid can be from the inlet opening 9 enters spool 11 through input channel 10, flow to impeller 4 from passage 8 then, flow into delivery outlet 7 through output road 6 again, impeller 4 can rotate under the effect of fluid, then impeller shaft 3 rotates simultaneously, impeller gear 24 on the impeller shaft 3 drives first transition gear 22 of engagement successively, second transition gear 21, spool driving gear 20, valve core gear 25, driven gear 14 rotates, then reply gear 13 and drive upward bar gear 19 revolutions, when last bar gear 19 turns round, the rotary position of handle 1 can reflect the output quantity of fluid, when reaching the fluid output quantity of setting, ratchet 30 breaks away from bayonet socket 32, then clockwork spring 29 releases energy, clockwork spring shaft gear 28 resets fast, then the valve core gear 25 on these clockwork spring shaft gear 28 drive valve core shafts 26 resets, thereby spool 11 is closed.
