Abstract
The invention discloses a method for measuring the volume of flammable liquid in a closed container filled with an explosion-proof material, wherein a pressure sensor is fixed at the bottom of the closed container and is connected with a digital conversion and display device through a lead; the oil filling amount and the reading of the pressure sensor are recorded in the oil filling process, the corresponding relation between the oil filling amount and the reading of the pressure sensor is programmed and input into the digital conversion and display device, and the digital conversion and display device can output the oil amount according to the reading of the pressure sensor. The method for separating the film is easy to operate, and can better eliminate the interference of the explosion-proof material on the measurement.
Description
Technical field
The invention belongs to machinery, transportation safety field, be specifically related to a kind of measuring method being filled with flammable liquid volume in the closed container of explosion-proof lamp.
Background technology
Oil ga(u)ge refers at the how many device of constant volume device acceptance of the bid stand oil amount (just).By oil ga(u)ge, we can know the number of oil mass in automobile.By oil ga(u)ge, we also can understand number of Fuel Oil Remaining in other closed containers etc.
Tradition oil ga(u)ge belongs to " liquid level display " by fuel contents gauge, leans against device floating drum in fuel tank, along with the minimizing of fuel oil, the floating drum floated on fuel level also and then can decline, the drive pointer of fuel contents gauge shows fuel oil storage.
Along with the progress of technology, at present in the world in order to ensure the safety of liquid oil plant, often in fuel tank or other airtight oil-receptacles, insert explosion-proof lamp.The material that this explosion-proof lamp right and wrong are closely knit, oil can in the space part bit flow of material.But this explosion-proof lamp is filled in after in the confined spaces such as fuel tank, the installation of original " floating drum " formula oil ga(u)ge of meeting obstacle and floating.Thus, after having laid explosion-proof lamp in fuel tank or other fuel container, original float-type oil ga(u)ge can not re-use.Therefore, need to find a kind of method can testing fuel tank (or other confined space) interior trapped fuel (or other flammable and combustible liquids) volume being placed with explosion-proof lamp newly, develop a kind of newly, be adapted to the oil ga(u)ge having laid explosion-proof lamp fuel tank (or depositing other closed container of flammable and combustible liquids).
Summary of the invention
The present invention is intended to overcome prior art defect, and object is to provide the oil that a kind of measurement is filled with explosion-proof lamp
The method and apparatus of oil mass and flammable liquid volume in case and other closed container.
The technical solution used in the present invention is: a kind of measuring method being filled with flammable liquid volume in the closed container of explosion-proof lamp, fixes a pressure transducer bottom closed container, and pressure transducer is connected with digital conversion and display device by a wire; In refueling process, record volume read-out and pressure sensor readings, and the corresponding relation compiled program of volume read-out and pressure sensor readings is inputted digital conversion and display device, digital conversion and display device can export oil mass according to pressure sensor readings.
Further improvement, the method be fixed on by pressure sensor bottom closed container is: first fixed by pressure sensor, then fill out explosion-proof lamp; Or be after populated explosion-proof lamp, push part explosion-proof lamp aside, fix pressure sensor, then fill remaining space with explosion-proof lamp.
Further improvement, described closed container is fuel tank.
Further improvement, described fuel tank is the fuel tank of all kinds of use gasoline, diesel oil and liquefied gas natural gas machine motor-car.
Further improvement, described flammable liquid is gasoline, diesel oil and liquefied natural gas (LNG).
Adopt separating film in this way, be easy to operation, better can get rid of explosion-proof lamp to the interference of measuring.
Accompanying drawing explanation
Fig. 1 is device schematic diagram of the present invention.
Embodiment
Below in conjunction with embodiment, the present invention will be further described, not limiting the scope of the invention.
embodiment 1
A kind of method and apparatus being applicable to measure oil mass and flammable liquid volume in the fuel tank and other closed container being filled with explosion-proof lamp.Gasoline car volume of fuel tank 80 liters, is fixed on sky tank bottoms by pressure transducer before explosion-proof lamp, and with wire by Signal transmissions out, then in fuel tank, add explosion-proof lamp, account for fuel tank volume about 1%.
Then in fuel tank, add gasoline in refuelling station gradually, until fill it up with, obtain different pressure datas.By not in the same time the corresponding relation of pressure data and oil mass be divided into form.Export in dial plate mode.As long as keep fuel tank size constancy, and the kind of oil is stablized, and the method is all effective.For different gasoline kinds, can be similar to and think that its density is basically identical.Obtain the fuel tank oil ga(u)ge being filled with explosion-proof lamp like this, can the situation of oil mass change in indicating mail box.
embodiment 2
A kind of measurement is filled with the method and apparatus of oil mass and flammable liquid volume in the fuel tank of explosion-proof lamp and other closed container.Gasoline car volume of fuel tank 80 liters, is fixed on sky tank bottoms by pressure transducer before explosion-proof lamp, and with wire by Signal transmissions out, then in fuel tank, add explosion-proof lamp, account for fuel tank volume about 1%.Then add hypothesis explosion-proof lamp Density Distribution in the whole space of fuel tank even, and keep stable when driving.Then in fuel tank, add gasoline in refuelling station gradually, until fill it up with, obtain different pressure datas.By not in the same time the corresponding relation of pressure data and oil mass be divided into form.Programming exports Fuel Oil Remaining situation of change in a digital manner.
As long as keep fuel tank size constancy, and the kind of oil is stablized, and the method is all effective.For different gasoline kinds, can be similar to and think that its density is basically identical.Obtain the fuel tank oil ga(u)ge being filled with explosion-proof lamp like this, can the situation of oil mass change in indicating mail box.
