Abstract

The utility model pertains to the mechanical valve technology field, in particular to a proportion valve that can control fluid flow, and consists of a valve body, a valve core, a handle, an input port and an output port. The utility model is characterized in that a gear is arranged on the rotating axis of the valve core, and a proportion-controlling mechanism is arranged on the valve body. The proportion-controlling mechanism comprises a wheel gearing and an impeller. The impeller is arranged inside the output port of the valve body and a gear is arranged on the rotating axis of the impeller. The gear matches the wheel gearing, and the wheel gearing matches the rotating axis of the valve core. Because the utility model adopts the structure of arranging a proportion-controlling mechanism on the valve body, when fluid flows out of the output port of the valve body, the impeller rotates under the action of fluid, and the gear arranged on the impeller drives the wheel gearing to work. When effluent fluid reaches a specified volume, the wheel gearing can drive the rotating axis of the valve core to rotate and close the valve automatically, thereby achieving the effect of controlling fluid output.

Description

Proportional valve

Technical field

The utility model belongs to the machinery valve technical field, particularly relates to a kind of proportional valve that can control fluid flow.

Background technique

In background technique, the traditional mechanical valve is mainly by valve body, handle, spool, the inlet opening, compositions such as delivery outlet, handle is connected the upper end of spool axle, 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 this valve is to adopt manual operations control from the amount of the fluid of outflow, 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 purpose of this utility model is to provide a kind of reasonable in design, compact structure, can controls the mechanical type proportional valve of fluid output quantity.

The technological scheme that the utility model adopted is achieved in that it comprises valve body, spool, handle, inlet opening and delivery outlet, it is characterized in that in the rotating shaft of described spool gear being housed, quantitative control mechanism is housed on described valve body, this quantitative control mechanism is made of gear drive and impeller, described impeller is arranged in the valve body delivery outlet, in the rotating shaft of impeller gear is housed, this gear matches with gear drive, and described gear drive matches with the rotating shaft of spool.

The utility model 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 utility model comprises valve body 5, spool 11, handle 1, inlet opening 9 and delivery outlet 7, in the rotating shaft 26 of described spool 11 gear 27 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, in the rotating shaft 3 of impeller 4 gear 24 is housed, this gear 24 matches with gear drive, and described gear drive matches with the rotating shaft 26 of spool 11; Described handle 1 rotating shaft 18 links with rotating shaft 26, gear 19 is housed in the rotating shaft 18, described gear drive is made of gear 19, gear 13, gear 28, gear 12, ratchet 30 and gear 27, gear 20, gear 21, gear 20, gear 14 and clockwork spring 29, described clockwork spring 29 is arranged on the gear 28, and described ratchet 30 can match with gear 13; Described gear 19 is meshed with gear 13, gear 13 is coaxial with gear 14 and gear 28, the gear 25 that gear 28 can drive when rotating in the rotating shaft 26 rotates, thereby make spool 11 be in opening state, when gear 28 rotates, rotate with its meshed gears 12, these gear 12 driven gears 32 rotate, then make the fastener 31 of ratchet 30 can be stuck in the bayonet socket 32 of gear 13, and clockwork spring 29 is tightened when 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 out delivery outlet 7 through output channel 6 again, impeller 4 can rotate under the effect of fluid, then rotating shaft 3 is rotated simultaneously, gear 14 in the rotating shaft 3 drives meshed gears 22 successively, gear 21, gear 20, gear 25, gear 14 rotates, then gear 13 driven gears 19 revolutions, during gear 19 revolutions, the rotary position of handle 1 can reflect the output quantity of fluid, when arriving the fluid output quantity of setting, fastener 31 on the ratchet 12 breaks away from bayonet socket 31, and then clockwork spring 29 releases energy, and gear 28 resets fast, then the gear 25 in these gear 28 drive spools 11 rotating shafts 26 resets, thereby spool 11 is closed.
