A kind of flow regulator
Technical field
The utility model relates to a kind of flow regulator.
Background technique
Existing flow regulator comprises in a valve body with feed-water end and waterexit end, the valve body being provided with the water port that the water port is provided with elastic ring.Its working principle is: when anhydrous or hydraulic pressure was little, elastic ring was indeformable or be out of shape for a short time, and the discharge area of crossing the water through hole is not had influence; When hydraulic pressure increased, the elastic ring compressive deformation was crushed, and made the discharge area of water passage hole diminish, thereby it regulates the effect of current.But existing valve body has following deficiency, referring to Fig. 6 to Fig. 9, existing two kinds of structure stoppers, wherein a kind of structure is seen Fig. 6, and this stopper 500 comprises a body, and the central osculum 510 of a diameter less than the body internal diameter established in the waterexit end of body, another kind of structure is seen Fig. 7, establishing a pedestal 610 in these stopper 600 bodies, be provided with spoke 620 between body and the pedestal, is osculum 630 between the spoke 620.Existing a kind of flow regulator 700, see DE20115440, the wall end of its valve body waterexit end is concordant with solid seat 710 bottoms, when this flow regulator and stopper 500 cooperations, because the diameter and water port 510 equal diameters of solid seat, should just hide this water port 510 by solid seat, current are obstructed.Disclose another kind of flow regulator 800 among the US3847178, it is located at central authorities with osculum 810, and when this flow regulator and stopper 600 cooperations, because pedestal 620 equal diameters of osculum 810 and stopper, current are obstructed.Therefore, when using different stoppers, must use the flow regulator of different structure, use inconvenience.
The model utility content

A kind of flow regulator, it comprises:
One valve body (100), it comprises that an overcoat (110), with feed-water end and waterexit end is located at solid (120) and the spoke (130) of some affixed overcoats (110) and solid seat (120) in the overcoat (110);
The buckle closure (200) of one band water port (210), it and overcoat (110) link together and it and overcoat (110) between be formed with assembly space; And
One flexible seal ring (300), it is positioned at assembly space, stuffing box gland, and to be connected on solid seat (120) outer and be supported by on spoke (130);
Wherein, the waterexit end of described overcoat (110) is provided with the projection (113) of the bottom (121) that protrudes in solid seat (120) on the axial direction, forms a space (400) between the bottom (121) of described projection (113) and solid seat (120).
Among one preferred embodiment: described buckle closure (200) comprises the solid bar (230) of the intersection in an outer ring (220) and the some affixed outer rings (220) at least, forms water port (210) between the described per two solid bars (230).
Among one preferred embodiment: described buckle closure (200) is connected with overcoat (110) by the buckle linkage structure, the interior turning surface of wherein said overcoat (110) is established a draw-in groove (111), the outer turning surface in outer ring (220) of described buckle closure (200) is established a snap ring (221), described snap ring (221) and adaptive connection of draw-in groove (111).
Among one preferred embodiment: described draw-in groove (111) is positioned on the solid seat (120).
Among one preferred embodiment: the spacing between described buckle closure (200) and the solid seat (120) is not more than seal ring (300) highly.
Among one preferred embodiment: the interior turning surface of described overcoat (110) evenly convexes with rib (112) at interval.
Among one preferred embodiment: described rib (112) is positioned between draw-in groove (111) and spoke (130).
Among one preferred embodiment: the described minimum diameter that is in seal ring (300) external diameter of free state less than a plurality of ribs (112) display, the described minimum diameter that is in seal ring (300) external diameter of deformation state greater than rib (112) display.
Among one preferred embodiment, described projection (113) is continuous projection or discontinuous projection.
The technical program is compared with background technique, and it has following advantage:
1, suitability of the present utility model is strong, and it can be applicable to two kinds of stoppers in the background technique simultaneously.Because the waterexit end of described overcoat is provided with the projection that is higher than solid seat bottom on the axial direction.When therefore being applied to stopper 500, water can be from the spatial flow between solid seat bottom and the projection to the osculum that is positioned at the middle part; When being applied to second kind of stopper 600, water directly enters the osculum of stopper the water port between spoke.
2, seal ring is enclosed within outside the solid seat, by the distortion of the seal ring hydraulic action under the gap between turning surface is changed and realizes the water saving effect, and then the seal ring distortion is sensitive, and water-saving result is good, and is easy to assembly, is convenient to realize that automation assembles; Seal ring is installed in the assembly space, cooperates by valve body and buckle closure to stop seal ring to break away from, and is convenient to seal ring and accurately locatees;
3, the spacing between buckle closure and the solid seat is not more than the seal ring height, can stop seal ring to break away from, and is convenient to accurately locate seal ring;
4, turning surface evenly convexes with rib at interval in the overcoat, and water-saving result is good, and the phenomenon of avoiding cutting off the water supply occurs.
