Description
Technical field
The present invention relates to a kind of flow regulator, particularly a kind of novel two-flow liquid discharge device for adjusting pipe end liquid outlet quantity.
Background technique
Pipe end is generally all equipped with tap, and this tap is for controlling water outlet or the shutoff of pipeline, and industry also carries out many improvement for spigot water outlet pipe end simultaneously.
As April 10 in 2013, the Chinese patent ZL201220476543.7 of bulletin disclosed a kind of bubbler, it sets up this device at the outlet pipe end of tap liquid is flowed out with the form of gas-vapor mix, this bubbler comprises a point water body, go out the network of rivers and shell, described casing circumference outer side wall is provided with air inlet duct, go out the network of rivers and be detachably located at shell inside bottom, dividing water body to be fitted together to is located in shell, cone structure is arranged to the tapping hole on time-division water body, to improve the flow velocity of water in point water body, improve inspiratory effects, thus also good foaming effect can be reached under low flow state.
The Chinese patent ZL201420303284.7 and for example announced on March 18th, 2015 discloses a kind of self-adjusting flow bubbler, and it comprises body portion, filter member, Flow-rate adjustment part and shunt; This filter member, Flow-rate adjustment part and shunt are located in body portion successively along water (flow) direction; This filter member and shunt are arranged with known form, this Flow-rate adjustment part comprises dunnage and flexible seal ring, this dunnage is provided with water flow hole, on the water flow hole that dunnage is located at by sealing circle and can resiliently deformable, when there is resiliently deformable under being located at the effect of the seal ring on this water flow hole in water flow pressure, the sectional area of flow channel changes, and corresponding flow changes.Specifically, when hydraulic pressure increases, when flow increases, seal ring is radially out of shape, and the sectional area of flow channel is reduced, thus flow reduces.When hydraulic pressure declines, when flow reduces, seal ring reduces by external force, and radial amount of deformation reduces, and the sectional area of flow channel is increased, thus increased flow capacity, this technological scheme adapts to the change of flow by the resiliently deformable of seal ring.
For another example the Chinese patent ZL201110023846.3 announced on July 25th, 2012 discloses a kind of rotary water-saving bubbler, and this bubbler has the shell of short tube shape, the water outlet being densely covered with numerous osculum and filter member; This shell has via hole; The flow rate adjusting mechanism that can carry out large and small Flow-rate adjustment is provided with in this shell; The gland that the boxed basement that this flow rate adjusting mechanism has water passage hole by bottom, spherical water part, swing arm and the top excessively that have water passage hole have water passage hole forms, this base and this gland cover mutually and be closely wrapped in this with closing crosses water part, and this swing arm stretches in this base through the via hole this shell from outside and crosses water part with this and be connected; This swing arm drives this to cross water part and rotates, and this water passage hole crossing water part is coordinated with the water passage hole of this base and the water passage hole of this gland and carries out large and small Flow-rate adjustment.The invention solves bubbler not tool water saving or the problem of flow regulating function.
Therefore, bubbler is as known flow cavitation result accessory, and have plenty of and can only carry out water outlet by the flow of setting, although the water-outlet quantity had can regulate, its complex structure, can not reset to the state of water saving after being used to complete.
