Description
Technical field
The utility model relates to Compressor Technology field, particularly relates to a kind of self-feed type and scrapes fuel tap.
Background technique
In the working procedure of upper oil lubrication reciprocating-piston compressor, the lubricant oil strictly forbidding in crankcase enters cylinder and is mixed into compressed medium, one is the turbidity test in order to ensure compressed medium, two is in order to safety, some special media becomes very inflammable and explosive after mixing with oil, or has chemical reaction to produce.
Piston rod in reciprocating-piston compressor runs through the crankcase of oil and the cylinder without oil, for avoiding piston rod lubricant oil brought into the splash lubrication oil that cylinder and crosshead high-speed motion produce and enter cylinder, arranging oil wiper in the middle extend neck between crankcase and cylinder becomes necessary.
Common oil wiper design, its attention focuses mostly on scraper ring, usual employing one group of metal scraper ring and a retable material scraper ring, or two groups of metal scraper rings add a retable material scraper ring, both added cost, also increased the friction of ring to piston rod, and piston rod was generated heat serious, scraper ring service life reduction, frictional work increases.And the scraper ring of monocycle pattern also cannot ensure that the lubricant oil on piston rod is thoroughly struck off.
Model utility content
Based on the technical problem that background technique exists, the utility model proposes a kind of self-feed type and scrape fuel tap.
Fuel tap scraped by a kind of self-feed type that the utility model proposes, and comprising: valve seat and be no less than a cambered surface; Valve seat is provided with the rod aperture can inserting piston rod, and rod aperture is by be interconnected and the first duct of dead in line and the second duct form; The downside inwall in the first duct is slope profile, and its one end away from the second duct is downward-sloping; Second duct is cylindrical bore, and its inwall is fitted with friction pad;
Cambered surface to be arranged on the inwall in the first duct by elastic component and to be positioned at above axis, and cambered surface is provided with multiple frizing thick stick be parallel to each other; Frizing thick stick is arcuate structure, and the center of circle corresponding to it is positioned on rod aperture axis, and its place plane is crossing perpendicular to the cross section of axis with rod aperture.
Preferably, valve seat is provided with scraper ring, and scraper ring is positioned at one end away from the second duct, the first duct, the annular distance of scraper ring and rod aperture dead in line.
Preferably, scraper ring is removably mounted on valve seat.
Preferably, frizing thick stick and cambered surface one-body molded.
Preferably, cambered surface is removably mounted on valve seat.
Preferably, friction pad is made up of rubber material.
Preferably, elastic component is spring or rubber.
The self-feed type that the utility model provides is scraped fuel tap and be may be used on carrying out frizing to piston rod in compressor.Particularly, drive in reciprocating motion of the pistons process at piston rod, rotate along axis by the driving mechanism piston rod in compressor, so, piston rod and the relative movement of frizing thick stick, frizing thick stick strikes off the lubricant oil on piston rod.The lubricant oil that frizing thick stick scrapes to drop in the profile of slope and discharges along slope profile, thus the lubricant oil scraped can be avoided to adhere on piston rod at this.
In the utility model, frizing thick stick is set to arcuate structure, and multiple frizing thick stick is parallel to each other, the effect of spiral relative movement of going forward one by one can be realized, so, by the laddering frizing of piston rod, be conducive to ensureing frizing effect, just the adhesion of lubricant oil stubbornness on the piston rod.In the utility model, corresponding to frizing thick stick, the center of circle is positioned on rod aperture axis, is conducive to frizing thick stick and fully fits on the piston rod.

Fig. 2 is that globoidal structure worm's eye view in fuel tap scraped by self-feed type;
Fig. 3 is that globoidal structure side view in fuel tap scraped by self-feed type.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, fuel tap scraped by a kind of self-feed type that the utility model proposes, and comprising: valve seat 1 and be no less than a cambered surface 2.Valve seat 1 is provided with the rod aperture 3 can inserting piston rod A, and rod aperture 3 is by be interconnected and the first duct 31 of dead in line and the second duct 32 form.
The downside inwall in the first duct 31 is slope profile, and its one end away from the second duct 32 is downward-sloping.Cambered surface 2 to be removably mounted on the inwall in the first duct 31 by elastic component 5 and to be positioned at above axis, cambered surface 2 is provided with one-body moldedly multiple frizing thick stick 6 be parallel to each other.Frizing thick stick 6 is arcuate structure, and the center of circle corresponding to it is positioned on rod aperture 3 axis, and its place plane is crossing perpendicular to the cross section of axis with rod aperture 3.
Second duct 32 is cylindrical bore, and its inwall is fitted with friction pad 4, and particularly, friction pad 4 is made up of rubber material.
The self-feed type that present embodiment provides is scraped fuel tap and be may be used on carrying out frizing to piston rod A in compressor.Particularly, drive in reciprocating motion of the pistons process at piston rod A, rotate along axis by the driving mechanism piston rod A in compressor, so, piston rod A and frizing thick stick 6 relative movement, the lubricant oil on frizing thick stick 6 pairs of piston rods strikes off.The lubricant oil that frizing thick stick 6 scrapes to drop in the profile of slope and discharges along slope profile, thus the lubricant oil scraped can be avoided to adhere on piston rod A at this.
In present embodiment, frizing thick stick 6 is set to arcuate structure, and multiple frizing thick stick 6 is parallel to each other, the effect of spiral relative movement of going forward one by one can be realized, so, by the laddering frizing of piston rod A, be conducive to ensureing frizing effect, just the sticking on piston rod A of lubricant oil stubbornness.In present embodiment, the center of circle corresponding to frizing thick stick 6 is positioned on rod aperture 3 axis, is conducive to frizing thick stick 6 and is fully fitted on piston rod A.
In present embodiment, the setting of elastic component 5, the relative distance flexibility and changeability of rod aperture 3 axis and cambered surface 2, thus the piston rod A user demand that can meet different model.Elastic component 5 specifically can be spring or rubber.
In present embodiment, the setting of friction pad 4, by the Relative friction between piston rod A, carries out further wiping to piston rod A.
In present embodiment, valve seat 1 is provided with scraper ring 7, and scraper ring 7 is positioned at one end away from the second duct 32, the first duct 31, the annular distance of scraper ring 7 and rod aperture 3 dead in line.Piston rod A inserts in rod aperture 3 through after scraper ring 7, and scraper ring 7 couples of piston rod A carry out frizing first, thus can reduce the working pressure of frizing thick stick 6.Particularly, scraper ring 7 is removably mounted on valve seat 1, to change scraper ring 7 according to the piston rod A of different-diameter.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
