Abstract
The utility model is that a kind of trackless equipment drainage type increases the anti-fuel lid that leaks, and comprise frosted upper cover (2), the upper port of described frosted upper cover (2) is connected with one-way breather valve (1), and frosted upper cover (2) below had been threaded connection scale (5); Cross scale (5) below and be welded with heightening frame (6); Heightening frame (6) is threaded with adopting between fuel tank; Heightening frame (6) inner side also arranges the filter core for being inserted in fuel tank; Cross scale (5) to be connected by seal ring (4) and tightening screw (3) with filter core.This fuel lid can effectively prevent underground trackless equipment in the course of the work oil plant from the appearance of fuel lid leak case, avoid the waste of oil seed production cost, reduce trackless equipment run potential safety hazard.
Description
Technical field
The utility model relates to a kind of trackless equipment drainage type and increases the anti-fuel lid that leaks.
Background technology
At current mining trackless equipment if the equipment such as scoper, truck is in real work, often there is a large amount of oil stain in reservoir port and tank surface, and along with period of service extend the leakage of oil frequency, quantity increases gradually, cause the waste of resource and the pollution to environment, and there is certain potential safety hazard.Mainly crude oil case lid sealing effectiveness is bad to analyze reason, and mine descending slope is relatively large, and in the process of inclination of vehicle, oil plant easily goes out to reveal from fuel lid.For this situation, rectification fuel lid Leakage, becomes problem in the urgent need to address.This research is intended to the fuel lid working out a kind of highly efficient durable, prevent fuel oil from leaking.
Crude oil case lid is designed to trim tank external and internal pressure two-way admittance, when fluid splashes, easily splashes away from fuel lid.In addition the working environment situation such as underground ramp is complicated, in the work area that the gradient is larger, driver refuel overfill when, fluid directly overflows from reservoir port.
When the engine operates, the consumption of system internal cause diesel oil, causes air pressure to reduce, and makes tank pressure be less than bar pressure outside fuel tank.For preventing tank pressure and bar pressure from having big difference, need the air pressure that a connection for bbreather pipe block comes inside and outside regulating oil tank.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of trackless equipment drainage type to increase the anti-fuel lid that leaks, solves fuel lid Leakage, overcome the defect of existing fuel lid.
The technical solution of the utility model is as follows:
Trackless equipment drainage type increases the anti-fuel lid that leaks, and comprises frosted upper cover, it is characterized in that the upper port of described frosted upper cover is connected with one-way breather valve, be threaded connection scale below frosted upper cover; Cross below scale and be welded with heightening frame; Adopt between heightening frame with fuel tank and be threaded; Filter core for being inserted in fuel tank is also set inside heightening frame; Cross scale and filter core is connected by seal ring and tightening screw.
Be provided with in filter core and be tiltedly installed with deflecting plate, below described deflecting plate, be also provided with the filter screen being arranged on filter core inner bottom part.
Good effect of the present utility model is:
One-way breather valve mainly plays trim tank inside and outside differential pressure, and valve block has the effect of one-way conduction, and namely when ambient pressure is less than tank pressure, the conducting of valve block, inside and outside differential pressure balances, and other situation valve blocks close.
Frosted upper cover outer rim adopts asperities process, and increasing friction force, facilitates fuel lid spinning in and out in refueling process.
The contact of seal ring principal security filter core interface is closely, oil tight.
Filter screen Main Function is the impurity in fluid, prevents impurity from entering fuel tank internal clogged oil line.Increase splashing oil liquid resistance simultaneously, reduce fluid splashing amplitude.
Deflecting plate is fixed in filter core, and in refueling process, fluid enters through deflecting plate after oil filling port, by filter screen after water conservancy diversion, enters fuel tank.In the course of the work, the fluid of splashing is after filter screen one-level stops, and deflecting plate plays secondary Intercepting effects, effectively reduces fluid splashing degree.
This oil tank cover sealing is effective, and oil plant leaks, flooded conditions seldom occurs, and while saving oil plant cost, reduces device security production hidden danger.Connection for bbreather pipe block one-way conduction, while preventing fuel oil from leaping up out, can effective regulating oil tank internal gas pressure.Application is threaded and welds, and reliability is strong, good sealing effect.The use of deflecting plate, prevents the generation adding oil whip, avoids the excessive oil plant that causes of injection flow to bloat situation generation, reduces oil plant splashing situation simultaneously and occur.Filter screen Main Function is the impurity in fluid, prevents impurity from entering fuel tank internal clogged oil line.Increase splashing oil liquid resistance simultaneously, reduce fluid splashing amplitude.6 case lid designs are ingenious, and structure is simple, and tooling cost is lower, long service life, and process easy for installation, popularizing application prospect is wide.
Through test, this fuel lid can effectively prevent underground trackless equipment in the course of the work oil plant from the appearance of fuel lid leak case, avoid the waste of oil seed production cost, reduce trackless equipment run potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
See Fig. 1, the utility model comprises frosted upper cover 2, and the upper port of described frosted upper cover 2 is connected with one-way breather valve 1, has been threaded connection scale 5 below frosted upper cover 2.Cross below scale 5 and be welded with heightening frame 6.Connection mode is solid and reliable, good airproof performance.Heightening frame 6 is threaded with adopting between fuel tank.Filter core for being inserted in fuel tank is also set inside heightening frame 6.Cross scale 5 to be connected with tightening screw 3 by seal ring 4 with filter core.
One-way breather valve 1 mainly plays trim tank inside and outside differential pressure, and valve block has the effect of one-way conduction, and namely when ambient pressure is less than tank pressure, the conducting of valve block, inside and outside differential pressure balances, and other situation valve blocks close.
In filter core, be provided with filter screen 7, be also provided with deflecting plate 8.
Frosted upper cover 2 outer rim adopts asperities process, and increasing friction force, facilitates fuel lid spinning in and out in refueling process.
The contact of seal ring 4 principal security filter core interface is closely, oil tight.
Filter screen 7 Main Function is the impurity in fluid, prevents impurity from entering fuel tank internal clogged oil line.Increase splashing oil liquid resistance simultaneously, reduce fluid splashing amplitude.
Deflecting plate 8 is fixed in filter core, and in refueling process, fluid enters through deflecting plate after oil filling port, by filter screen after water conservancy diversion, enters fuel tank.In the course of the work, the fluid of splashing is after filter screen one-level stops, and deflecting plate plays secondary Intercepting effects, effectively reduces fluid splashing degree.
