Abstract
The utility model relates to a calibrating apparatus for an air-filling machine of liquefied petroleum gas, which is mainly composed of a liquid standard metering tank, a liquid-gas balanced tank, a safety valve, a pressure sensor, a secondary instrument, a temperature sensor, etc. The arrangement of the liquid-gas balanced tank increases the measuring accuracy and the usage safety of the apparatus; various defects generated by the direct connection of the calibrating apparatus and a gas storage tank can be avoided; the integral apparatus can realize the miniaturization; the usage is safer, and the measurement is more accurate. Thus, the calibrating apparatus for an air-filling machine of liquefied petroleum gas is an ideal instrument of detection and quality supervision for the gas filling station of the liquefied petroleum gas for technical supervision departments.
Description
The utility model relates to a kind of liquefied petroleum device filling machine useful test device.
The liquefied petroleum gas dispenser calibrating installation is to be specifically designed to the gauging instrument that the liquefied petroleum gas dispenser measuring accuracy detects usefulness.Liquefied petroleum gas dispenser standard volume mensuration is a kind of on-site measurement method that in the past adopts usually both at home and abroad, because this method must be just can carry out under the condition of known fluid to be measured density value, therefore it only is suitable for using in the laboratory, is not suitable for in-site measurement.When carrying out in-site measurement with this method in addition, need calibrating installation directly is connected with gas-holder.The drawback of doing like this is: measure operating mode (to the mensuration of gas-holder force value etc.) and do not conform to tested filling machine field working conditions, measured value can not accurately reflect filling machine real work value, so measuring accuracy is relatively poor.Moreover in detection,, will involve gas-holder if calibrating installation goes wrong, therefore be unfavorable for safety assurance.
The purpose of this utility model just provides a kind of novel liquefied petroleum gas dispenser calibrating installation, and its adopts standard volume metering and the method for weighing and combining, and the correction by temperature, force value detects the volume calculation precision of liquefied petroleum gas dispenser.
The utility model is achieved in that this calibrating installation mainly is made up of liquid standard test tank 1, liquid gas balance tank 3, safety valve 2, pressure transducer 4, secondary instrument 6, temperature sensor 7 etc., and liquid gas balance tank 3 is connected liquid standard test tank 1 by pressure transducer 4 with safety valve 2.Secondary instrument 6 two ends connect pressure transducer 4 and temperature sensor 7 respectively.Liquid standard test tank 1 is provided with standard inflation inlet 5, and connects temperature sensor 7, and is connected with gas station fluid reservoir 10 by fast joint 8 and pump 9.
This instrument joins by standard inflation inlet and filling machine, by the standard meter measuring tank liquefied petroleum gas (LPG) is carried out volume V metering, temperature T and pressure P data by temperature and pressure sensor acquisition liquefied petroleum gas (LPG), fill liquid weight W by the electronic scales measurement, density and bulking value V when calculating 15 ℃ of liquefied petroleum gas (LPG) by above data V, T, P, W again
15, at last by formula [(V
15-V
s)/V
15] * 100% is calculated the precision of liquefied petroleum gas dispenser.(V
sIndicating value for liquefied petroleum gas dispenser).
This utility model has added the liquid gas balance tank that is independent of outside the liquid standard test tank, calibrating installation directly is connected with filling machine, realized fluid to be measured is measured directly and accurately, thereby avoided original device because of can only be by density and gravimetric value indirect calculation fluid to be measured volume, and the generation of factor such as the measuring accuracy that causes is poor, trivial operations, safety are unfavorable.Simultaneously, it can play the stable equilibrium effect to the aeration quantity of liquid standard test tank, can regulate standard meter measuring tank charge pressure.
This calibrating installation can only carry out the test of a liquefied petroleum gas (LPG) weight when the different filling machines to same gas station detect, can alleviate testing staff's workload greatly, and pass through the comparison of the measured value of liquefied petroleum gas (LPG) Weight Calculation value and electronic balance, supervise the reliability of testing result at any time.This calibrating installation can also detect the density value of liquefied petroleum gas (LPG) when the filling machine measuring accuracy is examined and determine, can the quality of the liquefied petroleum gas (LPG) of gas station be exercised supervision, thereby embodied the multifunctionality of this instrument.This calibrating installation volume is little, uses flexibly, and is easy to operate, safe, reliable, is specially adapted to on-the-spot random measurement, is that technical supervision department carries out the desirable instrument that quality supervision detects to lpg service station.
