Abstract
The utility model relates to a diesel oil tank suitable for an oil gun with large caliber, belongs to the technical field of a fuel tank, and aims to solve a problem that diesel oil is liable to gush backward when an oil gun with large caliber runs again. The diesel oil tank suitable for an oil gun with large caliber comprises a tank body, an oil filler pipe and a oil level control valve. The lower pipe port of the oil filler pipe is connected with the tank body. The oil level control valve is arranged on the top wall of the tank body. The outlet of the oil level control valve is communicated with the upper portion of the oil filler pipe. The diesel oil tank is characterized in that a rotary valve is disposed on the topmost of the top wall of the tank body for auxiliary exhausting. During the operation of fueling up of oil, the air above the diesel oil is discharged via the oil level control valve and the rotary valve. With the constant rising of diesel oil level, the float of the oil level control valve also rises slowly along with the oil level, and till the oil level control valve is completely closed by the float, then the oil level control valve stops discharging the air, and the oil gun automatically stops fueling. After the oil gun automatically stops fueling, an oil filling worker starts the oil gun again, and the air at the top of the diesel oil tank keeps being discharged via the rotary valve, thereby effectively solving the problem of backward gushing of the oil.
Description
Technical field
The utility model relates to a kind of diesel fuel tanks that is applicable to the heavy caliber oil gun, belongs to the fuel tank technical field.
Background technology
Existing diesel fuel tanks comprises casing, fuel filler pipe and level control valve (LCV), and the lower nozzle of fuel filler pipe is connected on the casing, and level control valve (LCV) is installed on the roof of casing, and the outlet of level control valve (LCV) is communicated with the top of fuel filler pipe.Level control valve (LCV) is used to control volume read-out, when oil gun insertion fuel filler pipe is annotated diesel oil, the air of diesel oil top discharges by level control valve (LCV), along with the diesel oil liquid level constantly rises, the float of level control valve (LCV) also along with liquid level rises at leisure, cuts out level control valve (LCV) up to float fully, this moment, level control valve (LCV) stopped exhaust, nozzle produces jumps rifle, and behind the jumping rifle, personnel mend rifle by oiling.
The bore of normal nozzle is about 24mm, and an additional amount when mending rifle is little, can not cause counter gushing when mending rifle.The bore of heavy caliber oil guns such as OPW7H type reaches about 30mm.When adopting the heavy caliber oil gun to refuel, because the muzzle footpath is thick, an additional amount when mending rifle is big, and it is fast to add speed oil, and it is very big to cause air pressure moment at fuel tank top when mending rifle to be increased, and causes diesel oil to gush to filler neck is counter easily.
Roll-over valve is usually used on the gasoline fuel tank, because the gasoline volatilization amount is big, need under the mode of operation by roll-over valve constantly to the canister exhaust, the free air capacity of roll-over valve is big less than level control valve (LCV), and roll-over valve also has when inclination of vehicle or upset and prevents that gasoline from leaking into the effect in the oil vapour pipeline.Because the volatility of diesel oil is little, does not need exhaust in normal operation, so does not see the use roll-over valve on the diesel fuel tanks.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of diesel fuel tanks that is applicable to the heavy caliber oil gun is provided, and counter the emerging in large numbers that can eliminate when mending rifle resembles.
For solving above technical matters, a kind of diesel fuel tanks that is applicable to the heavy caliber oil gun provided by the utility model, comprise casing, fuel filler pipe and level control valve (LCV), the lower nozzle of described fuel filler pipe is connected on the described casing, described level control valve (LCV) is installed on the roof of described casing, the outlet of level control valve (LCV) is communicated with the top of described fuel filler pipe, and the roof highest point of described casing is equipped with the roll-over valve of auxiliary exhaust, and atmosphere is led in the outlet of described roll-over valve.
With respect to prior art, the utility model has been obtained following beneficial effect: when oil gun insertion fuel filler pipe is annotated diesel oil in diesel fuel tanks, the air of diesel oil top is by level control valve (LCV) and roll-over valve discharging, and the common exhaust of level control valve (LCV) and roll-over valve is accelerated exhaust velocity.Along with the diesel oil liquid level constantly rises, the float of level control valve (LCV) also along with liquid level rises at leisure, cuts out level control valve (LCV) up to float fully, and this moment, level control valve (LCV) stopped exhaust, and nozzle produces jumps rifle; After jumping rifle, when the oiling personnel mended rifle, the air at diesel fuel tanks top continued to efficiently solve anti-problem of gushing by the roll-over valve discharging.
Description of drawings
Fig. 1 is applicable to the structural representation of the diesel fuel tanks of heavy caliber oil gun for the utility model.
Among the figure: 1 casing; 2 fuel chargers; 3 fuel filler pipes; 4 level control valve (LCV)s; 5 roll-over valve.
The specific embodiment
As shown in Figure 1, the utility model is applicable to that the diesel fuel tanks of heavy caliber oil gun comprises casing 1, fuel filler pipe 3 and level control valve (LCV) 4, fuel charger 2 is installed in the casing 1, the lower nozzle of fuel filler pipe 3 is connected on the casing 1, level control valve (LCV) 4 is installed on the roof of casing 1, the outlet of level control valve (LCV) 4 is communicated with the top of fuel filler pipe 3, and the roof highest point of casing 1 is equipped with the roll-over valve 5 of auxiliary exhaust, and atmosphere is led in the outlet of roll-over valve 5.
When oil gun insertion fuel filler pipe 3 was annotated diesel oil in casing 1, the air of diesel oil top was by level control valve (LCV) 4 and roll-over valve 5 dischargings, and level control valve (LCV) 4 and roll-over valve 5 common exhausts make the exhaust velocity quickening.Along with the diesel oil liquid level constantly rises, the float of level control valve (LCV) 4 cuts out level control valve (LCV) 4 up to float fully also along with liquid level rises at leisure, and this moment, level control valve (LCV) 4 stopped exhaust, and nozzle produces jumps rifle.After jumping rifle, when the oiling personnel mended rifle, the air at diesel fuel tanks top continued to efficiently solve anti-problem of gushing by roll-over valve 5 dischargings.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
