Abstract
The utility model provides a simple structure is small and exquisite, sealed reliable, difficult jam, the installation is dismantled conveniently, the manufacturability is good, the easy location be used for little flow system's current limiting device, including can placing at the intraoral tubulose current-limiting ring of pipeline entry, set up the hoop recess at current-limiting ring lateral surface, inlay the rubber O shape circle that is used for sealed pipeline and current-limiting ring in the hoop recess, the welding is at the filter screen of tubulose current-limiting ring entry department, the current-limiting plate of setting between current-limiting ring entry and export, the current-limiting aperture of setting at the current-limiting plate center.
Description
Technical field
The utility model relates to a kind of current-limiting apparatus, relates in particular to the flow regulator of liquid Hydraulic Power System.
Background technique
The current-limiting apparatus of using at present is of a great variety, has current-limiting components that the current limliting joint is also arranged, referring to Fig. 1, have also the having of band filter screen not to be with filter screen, and what absolute construction was arranged also has an independent structure.But comprehensive contrast, above-mentioned various structures all have the some shortcomings part.For example part current-limiting apparatus volume is big, no filter screen, only is suitable for the big environment of flow and is inappropriate for the small flow environment; The current-limiting apparatus sealing effect that has is bad, causes inside and outside leakage easily; The current-limiting apparatus that has is simple in structure but be not easy to processing dismounting.The current-limiting apparatus location that has is unreliable, and current-limiting apparatus is prone to move axially.Need be for a kind of simple, reliable, easy installation and removal of small flow system applies design, be prone to the current-limiting apparatus of location.
The model utility content
In order to solve the above-mentioned technical problem that exists in the background technique, the utility model provide a kind of simple in structure small and exquisite, sealing is reliable, be difficult for obstruction, easy installation and removal, good manufacturability, be prone to the current-limiting apparatus that is used for the small flow system of location.
The technical solution of the utility model is: a kind of current-limiting apparatus that is used for the small flow system is characterized in that: comprise tubulose current limliting circle, the circumferential groove that is arranged on current limliting circle outer side surface that can be placed in the pipeline inlet, be embedded in the rubber o-ring, the filter screen that is welded on tubulose current limliting circle ingress that are used for sealing pipeline and current limliting circle in the circumferential groove, be arranged on flow-limiting plate between the current limliting circle entrance and exit, be arranged on the current limliting aperture at flow-limiting plate center.
Above-mentionedly comprise that also being arranged on current limliting irises out at least two removal holes on the oral-lateral wall.
The advantage of the utility model:
1, the utility model current-limiting apparatus is made up of current limliting circle, filter screen and the rubber o-ring of special construction, is installed in motor inlet or branch line inlet.The current-limiting apparatus of this structure is through the sealing of the rubber o-ring on current limliting ring outer wall upstream and downstream medium, and the fixed current limiting device can prevent that generally speaking current-limiting apparatus from moving axially in joint inside simultaneously; Prevent that through filter screen fifth wheel, greasy dirt etc. from stopping up, polluting metering hole; Aperture through the outlet wall is for convenience detach, and volume is little simultaneously, structural strength is high.
2, independent, the good manufacturability of the utility model structure, easy installation and removal, inside and outside sealing is reliable, effectively prevents to stop up and locate problems such as not firm.
3, the utility model overall volume is small and exquisite, can easily be placed on M14 even littler pipe nipple inside.
Description of drawings
Fig. 1 is the structural representation of existing current-limiting apparatus;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the scheme of installation of the utility model;
Wherein: 1-current limliting circle; The 2-filter screen; The 3-flow-limiting plate; The 4-circumferential groove; The 5-metering hole; The 6-removal hole; The 7-rubber o-ring.
Embodiment
Referring to Fig. 2 and Fig. 3, the utility model provides a kind of current-limiting apparatus, is made up of current limliting circle 1, filter screen 2 and rubber o-ring; Current limliting circle 1 includes notch portion and exit portion, and intake section and exit portion communicate through the metering hole 5 that is arranged on the current limliting circle 1 middle flow-limiting plate 3, and metering hole 5 is used to regulate flow; Exit portion outer wall be provided with two removal holes 6, make that dismounting is more convenient; Inlay in the circumferential groove 4 of current limliting circle 1 outer wall rubber o-ring 7 is installed, be used to prevent internal leakage, improve the Flow-rate adjustment precision, can also play the effect of location simultaneously; Filter screen 2 is welded on the entry end right side round platform of current limliting circle 1, can prevent effectively that fifth wheel and greasy dirt impurity from stopping up, polluting metering hole 5.
Claims (2)
1. current-limiting apparatus that is used for the small flow system is characterized in that: comprise tubulose current limliting circle, the circumferential groove that is arranged on current limliting circle outer side surface that can be placed in the pipeline inlet, be embedded in the rubber o-ring, the filter screen that is welded on tubulose current limliting circle ingress that are used for sealing pipeline and current limliting circle in the circumferential groove, be arranged on flow-limiting plate between the current limliting circle entrance and exit, be arranged on the current limliting aperture at flow-limiting plate center.
2. the current-limiting apparatus that is used for the small flow system according to claim 1 is characterized in that: comprise that also being arranged on current limliting irises out at least two removal holes on the oral-lateral wall.
