Abstract
The present invention relates to a kind of self-regulation reduced velocity flow device, this reduced velocity flow device comprise reducing gear and with the matching used housing of reducing gear and end cap, reducing gear is made up of fan-shaped link press span and sprue, fan-shaped link press span 3 blades are mutually 120 ° of angles, middle the heart channel of Hang-Shaoyin rolling bearing of link press span to be connected in housing and freely to rotate in housing, sprue is circular arc, is connected to the end of fan-shaped link press span, matches with the inner shape of housing.Compared with prior art, the present invention is under the effect of current, sprue is by rotating, often turn over 120 ° just by import shutoff once, when flow velocity increases, corresponding sprue 4 rotational angular velocity increases thereupon, and sprue also increases the frequency that import is blocked thereupon, and final flow rate and angular velocity reach a balance.
Description
Technical field
The present invention relates to a kind of flow rate adjustment device, especially relate to the self-regulation reduced velocity flow device of a kind of reduction and stable liquid flow velocity.
Background technique
Now a lot of local, particularly big city, in order to supply water to high-storey, often all add very high hydraulic pressure, and for low floor user, this is unwanted, also therefore causes the waste of water resources time most.Such as: often a dozen are turned on the tap to stay in the user of ground floor, toward dirty like water just sprays, can spatter simultaneously and to obtain water all over the body.According to the incomplete statistics of online friend, China's every day is because the excessive and wasting water resources of water flow velocity just reaches 144000 tons.
At present, have a lot of device reducing flow velocity on the market, conventional point just as towel parcel water tap, hygienic issues is very important; Advanced point by conputer controlled, technical merit is high, is difficult to popular, equally also wastes resource.Also has similar product on the market, but their working principle is the adjustment utilizing propeller cavitation to carry out rotating speed, the method is when water flow velocity is larger, the rotating speed of propeller cavitation will be larger, this regulative mode relatively can only reduce water flow velocity, can not fundamentally be controlled by water flow velocity in a certain stability range; Say still very limited from resources conservation aspect.
Summary of the invention
Object of the present invention be exactly provide to overcome defect that above-mentioned prior art exists a kind of easy to use, can reduce and the self-regulation reduced velocity flow device of stable liquid flow velocity.
Object of the present invention can be achieved through the following technical solutions:
A kind of self-regulation reduced velocity flow device, between the import being arranged on pipeline and outlet, this reduced velocity flow device comprise reducing gear and with the matching used housing of reducing gear and end cap.
Described reducing gear is made up of fan-shaped link press span and sprue, described fan-shaped link press span becomes a common practice flabellum shape structure, there are 3 blades being mutually 120 ° of angles, middle the heart channel of Hang-Shaoyin rolling bearing of link press span to be connected in housing and freely to rotate in housing, described sprue is circular arc, be connected to the blade end of fan-shaped link press span, match with the inner shape of housing.
Angle between described blade and fan-shaped link press span central axis is 45 °.
The end of described blade arranges the projection connecting sprue.
Described sprue is arranged the cascade groove matched with the projection of blade end.
The joint of described housing and conduit entrance one end is provided with circular groove, and the shape of this groove and the shape of described sprue match.
Compared with prior art, in use, fluid flows into from the inlet of pipeline in the present invention, under action of a fluid, fan-shaped link press span drives three sprues to rotate together, often turns over 120 degree and just blocks once by import, so just can play the effect slowing down water velocity.Flow velocity increases, corresponding sprue rotational angular velocity increases thereupon, sprue also increases the frequency that import is blocked thereupon, flow velocity is coordinated mutually with sprue rotational angular velocity, so just can water flow velocity be stabilized within the scope of certain, can reduce and stationary flow speed, and without any need for additional annex, can well economize on resources.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of self-regulation reduced velocity flow device, as shown in Figure 1-2, between the import being arranged on pipeline and outlet, this reduced velocity flow device comprises reducing gear 1, housing 2, end cap 8, two rolling bearings 9 to its structure; Reducing gear 1 comprises a fan-shaped link press span 3 and three sprues 4, and the projection 10 of fan-shaped link press span blade end coordinates with the step groove 11 of sprue, fixes with M3 bolt 5; 120 ° are mutually between fan-shaped link press span 3 three blades; The structure of sprue 4 as shown in Figure 3, in circular arc, is coincide with the circular groove 6 that housing is offered and is provided with the step groove 11 be connected that to match with the projection 10 of fan-shaped link press span 3.Housing 2 and end cap 8 respectively have the position of laying rolling bearing 9, and housing 2 and end cap 8 coordinate the cavity 7 formed that reducing gear 1 can be allowed freely to rotate.The structure of circular groove 6 as shown in Figure 4, is arranged on the joint of housing 2 and conduit entrance one end.
The present invention is arranged on pipeline, and pipe is connected on inlet and outlet respectively.During normal work, the liquid fluid of high-voltage high-speed flows into from import, and reducing gear 1 rotates under liquid fluid effect, and flow rate of liquid reduces; Meanwhile, sprue 4 just often turns over 120 ° to import shutoff once.If inlet velocity increases, reducing gear 1 rotational angular velocity ω increases thereupon, and the frequency of sprue 4 shutoff import also improves thereupon, and flow velocity and frequency finally can reach a balance, this makes it possible to make exit velocity keep stable.This can stop the unnecessary waste caused because flow velocity is excessive from source.The present invention can comprehensively install, and making material, can not only, with regulating water flow velocity in daily life, also may be used on engineering regulating various liquid fluid flow velocity depending on actual conditions change.
Although invention has been described by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only signal; instead of restriction; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the scope that present inventive concept and claim protect, can also make a lot of distortion, these all belong within protection of the present invention.
