Abstract

The invention discloses a hydraulic closed oil tank oil scale corresponding to the temperatures. The hydraulic closed oil tank oil scale comprises a graduation ruler (3), a top cover (1), a corrugated pipe (2), a pressing plate (4), an adjusting spring (7), a locking nut (8) and an indicating plate (9). The top cover (1) is in welding connection with the corrugated pipe (2) and an adjusting valve sleeve (5), the adjusting valve sleeve (5) is arranged in the middle of the corrugated pipe (2), the graduation ruler (3) and the pressing plate (4) are welded and then are in bolt connection with the corrugated pipe (2), the adjusting spring (7) and an adjusting valve element (6) are placed in the adjusting valve sleeve (5), the graduation ruler (3) lines out scales according to the volume changing amount of oil liquid under the different temperatures, and abuts against the top end of the adjusting valve element (6) so as to push the adjusting valve element into the oil tank, and air and part of oil liquid in the oil tank are discharged. The front end of the graduation ruler (3) is automatically limited, and redundant oil liquid is drained. According to the oil scale, the fuel-injection quantity of the closed oil tank is determined according to the environment temperatures, the structure is simple, and the reliability is good.

Description

A kind of hydraulic closed fuel tank oil scale corresponding with temperature
Technical field
The present invention relates to a kind of hydraulic closed fuel tank oil scale, particularly a kind of hydraulic closed fuel tank oil scale corresponding with temperature.
Background technology
General hydraulic system adopts open type oil tank, fuel tank top communicates with atmosphere, the oil scale adopting comprises rule, conduit, oil scale is arranged on fuel tank side by bolt, on fuel tank, there is the hole communicating with conduit, according to U-shaped pipe principle, can determine the fluid amount of injecting from the external world by observing conduit liquid level.And sealed reservoir does not communicate with atmosphere, cannot adopt the oil scale of open type oil tank, and the hydraulic oil injecting is because environment temperature is different, the fluid volume being enclosed in cavity volume changes variation with temperature, therefore inject fluid number also should be different with temperature, if but the fuel tank oil scale corresponding with temperature not cannot be determined injection flow, there will be injection flow to cause not hydraulic system to work, or injection flow too much make the abnormal fault raising of hydraulic system pressure.
Summary of the invention
The object of the invention is to provide a kind of hydraulic closed fuel tank oil scale corresponding with temperature, solves and under different temperatures, determines the oil mass problem of injecting.
A hydraulic closed fuel tank oil scale corresponding with temperature, comprising: rule, also comprises: top cover, corrugated tube, pressing plate, adjusting valve pocket, regulating spool, regulating spring, set nut and indicator board.Top cover is as enclosing cover and the bellows-welding of sealed reservoir, after rule and pressing plate welding and corrugated tube one end is bolted, variable valve is placed on corrugated tube middle part also and bellows-welding, regulating spring, regulating spool are placed in the center pit that regulates valve pocket successively, regulating spring is placed in the bottom that regulates valve pocket, regulating spool is pushed down regulating spring, indicator board is placed in set nut and regulates between valve pocket, regulating spool is pushed down in set nut lower end, set nut is threaded with variable valve cover top, and regulating spool and regulating spring move in regulating valve pocket; Regulate valve pocket to move with corrugated tube.
Rule high scale calculates at the volume change under different temperatures according to fluid, when fluid injects fuel tank, corrugated tube is compressed, top cover, pressing plate and rule are not subjected to displacement, regulate valve pocket, regulating spool, regulating spring, set nut and indicator board to move to compressed direction with corrugated tube, until indicator board stops oiling after pointing to environment temperature scale corresponding on rule, determined the injection fluid amount at varying environment temperature.With instrument, withstand regulating spool top, regulating spool advances to fuel tank internal, and regulating spring is compressed, emits the air containing in fuel tank, also at fluid, injects and emits part fluid when too much.Rule front end stops continuation motion when regulating spool moves to extreme position, plays automatic spacing effect, emits simultaneously and injects too much fluid.
This oil scale can be determined sealed reservoir injection flow according to environment temperature, has advantages of simple in structure, good reliability, easy to operate.

Embodiment
A hydraulic closed fuel tank oil scale corresponding with temperature, comprising: rule 3, also comprises: top cover 1, corrugated tube 2, pressing plate 4, adjusting valve pocket 5, regulating spool 6, regulating spring 7, set nut 8, indicator board 9.Top cover 1 is welded to connect as enclosing cover and the corrugated tube 2 of sealed reservoir, after rule 3 is welded to connect with pressing plate 4 and corrugated tube 2 one end are bolted, adjusting valve pocket 5 occupy corrugated tube 2 middle parts and corrugated tube 2 is welded to connect, regulating spring 7, regulating spool 6 are positioned in the center pit that regulates valve pocket 5, regulating spring 7 is placed in the bottom that regulates valve pocket 5, regulating spool 6 is pushed down regulating spring 7, indicator board 9 is placed in set nut 8 and regulates between valve pocket 5, regulating spool 6 is pushed down in set nut 8 lower ends, and set nut 8 is tightened in and regulates valve pocket 5 tops.Regulating spool 6 and regulating spring 7 can move in regulating valve pocket 5; Regulate valve pocket 5 with corrugated tube 2 motions.
Its principle of work is: rule 3 high scales are according to using fluid to calculate at the volume change under different temperatures, when fluid injects fuel tank, corrugated tube 2 is compressed, top cover 1, pressing plate 4, rule 3 are not subjected to displacement, regulate valve pocket 5, regulating spool 6, regulating spring 7, set nut 8, indicator board 9 to move to compressed direction with corrugated tube 2, until indicator board 9 stops oiling after pointing to environment temperature scale corresponding on rule 3, determined the injection fluid amount at varying environment temperature.With instrument, withstand regulating spool 6 tops and advance to fuel tank internal, regulating spring 7 is compressed, can emit the air containing in fuel tank, also can inject and emit part fluid when too much at fluid.Rule 3 front ends can stop continuation motion when regulating spool 6 moves to extreme position, play automatic spacing effect, emit simultaneously and inject too much fluid.
