Abstract
The utility model relates to a civil oil meter of a rotary wing type, belonging to a flow rate measuring instrument. The utility model comprises a casing (7), an impeller box (4), an impeller (5), an indicating mechanism (1) and a center gear (6). Two O-shaped sealing rings (3) are respectively arranged in an inlet and an outlet, and the O-shaped sealing rings (3) are tightly pressed on the outer wall of the impeller box (4) by two fastening screws (2) whose centers have holes in the inlet and the outlet, which causes measured liquid (light oil) to directly enter the impeller box (4) and not enter the inner cavity of the casing (7) so as to realize measuring tiny flow rate (0.2-1 L/h) of civil fuel.
Description
The utility model belongs to flow measurement instrument, is specifically related to the civilian oil meter of a kind of rotary wind type.
The employed fuel of a part of regional resident of China is a kind of accessory of oil--lightweight oil at present.Use this oil to act as a fuel, have economy, convenience, pollute advantages such as little, so usable range is in continuous expansion.But the flow during owing to use is less, is about 0.2～1L/h, do not have suitable measuring instrument, so measurement problem is not resolved.
The purpose of this utility model is to provide a kind of civilian oil meter of rotary wind type of measuring tiny flow quantity.
The utility model contains housing 7, impeller box 4, impeller 5, indicating mechanism 1, central gear 6, also contain two " O " RunddichtringOs 3, make fluid to be measured (lightweight oil) impeller box 4 of only flowing through, and do not enter housing 7 inner chambers, two " O " RunddichtringOs are fastening by two porose trip bolts 2 of the center in importing and exporting, the diameter of the oil supply hole of impeller box 4 is 0.4mm, with precision and the sensitivity that guarantees to measure.
Be described further below in conjunction with accompanying drawing:
Figure one is the structural representation of the civilian oil meter of rotary wind type.
In the drawings, (1) is indicating mechanism, and (2) are trip bolt, and (3) are " O " RunddichtringO, and (4) are impeller box, and (5) are impeller, and (6) are central gear, and (7) are housing." O " RunddichtringO 3 by screwing trip bolt 2, is pressed on impeller box 4 outer walls " O " RunddichtringO 3 between impeller box 4 and trip bolt 2.When lightweight oil flows into oil meter, diameter on center pit by trip bolt 2, " O " RunddichtringO 3, the impeller box 4 is that the micropore of 0.4mm enters in the impeller box 4, rely on the tangential force effect of fluid, impeller 5 is rotated, pass through magnetic coupling, drive central gear 6 and rotate, show reading by indicating mechanism 1.Because the sealing function of " O " RunddichtringO 3, make fuel oil can only flow through impeller 4 and do not enter housing 7 inner chambers, thereby guaranteed the precision and the sensitivity of small amount of flow measuring.
Advantage of the present utility model is:
1. simple in structure, volume is little, and cost is low.
2. realized civilian fuel oil small flow rate measurement.
Claims (3)
1. civilian oil meter of rotary wind type, contain housing (7), impeller box (4), impeller (5), indicating mechanism (1), central gear (6), it is characterized in that: also contain two " O " RunddichtringOs (3), make the fluid to be measured impeller box (4) of only flowing through, and do not enter housing (7) inner chamber.
2. the civilian oil meter of rotary wind type as claimed in claim 1 is characterized in that: described two " O " RunddichtringOs (3) are fastening by porose two trip bolts (2) in the center in importing and exporting.
3. the civilian oil meter of rotary wind type as claimed in claim 1 is characterized in that: the diameter of the oil supply hole of described impeller box (4) is 0.4mm.
