Another object of the present invention is also to provide utilizes said apparatus to carry out the method for gas automatic gauge, and the method principle is reliable, easy and simple to handle, has wide market outlook.
For reaching above technical purpose, the present invention by the following technical solutions.
A kind of gas self-measuring device, mainly by shell, guidance panel, view window, precision glass cylindrical shell, pressure transducer, upper and lower lead limit switch, sample intake passage and sample output passage composition, described case surface is embedded with guidance panel and view window, in shell, there are two glass cylindrical shells, pressure transducer is arranged at the top of each glass cylindrical shell, and be connected sample intake passage by gas admittance valve with air outlet valve, sample output passage, there are piston and piston rod in the inside of glass cylindrical shell, bottom is connected with ball screw, the right and left of described ball screw has support, up stroke limit switch is arranged at the top of support, down stroke limit switch is arranged at bottom, described ball screw bottom is connected with motor, driving ball screw to rotate by motor drives piston rod and piston to move up and down in glass cylindrical shell, described pressure transducer, gas admittance valve, air outlet valve, upper and lower lead limit switch, motor is controlled automatically by guidance panel.
This device, for the volume metering of gas test experience, is a rectangular parallelepiped, and shell surrounds the parts such as glass cylindrical shell, motor, and there are view window and control panel in the front of device, can see the metering process of gas in built-in glass cylindrical shell by view window.Piston rod in glass cylindrical shell is connected with precise ball screw, is rotated the stroke up and down of realizing piston by driven by motor precise ball screw.Pressure transducer, gas admittance valve and air outlet valve are arranged at the top of glass cylindrical shell, realize the cycle metering of origin-to-destination by limitation travel switch.
Utilize said apparatus to carry out the method for gas automatic gauge, comprise: the gained gas after gas-liquid separation experiment enters in the first glass cylindrical shell by sample intake passage, pressure transducer detects that pressure changes, driven by motor ball screw rotates, thereby drive piston rod to move down, gas starts to be full of the first glass cylindrical shell, in the time that the tolerance of the first glass cylindrical shell reaches the predefined volume of control panel, automatically close the gas admittance valve of the first glass cylindrical shell, now to move up and down the pressure setting in the first glass cylindrical shell be atmospheric pressure to Electric Machine Control piston rod and record gas volume, the simultaneously inlet open of the second glass cylindrical shell repeat the course of work (metering, storage gas) of the first glass cylindrical shell, then the air outlet valve of the first glass cylindrical shell is opened, gas flows out by sample output passage, pressure in the first glass cylindrical shell reduces, piston moves upward until the force value in the first glass cylindrical shell comes back to atmospheric pressure, so circulation can complete the gage work of continuous gas, upper and lower lead limit switch attended operation panel, completes the autostore of gas data.
Because pressure detection, piston move and upper and lower lead limit switch is all automatically to be controlled by guidance panel, so can realize the metering of high flow in the situation that of no worker monitor.
Compared with prior art, the present invention has following beneficial effect:
(1) adopt two glass cylindrical shells, make gas constantly in gas collection and exhaust process, thereby make gas dosing scope larger;
(2) guidance panel automatic gauge storage data, make gas dosing process more accurate, and the error of generation is less;
(3) the present invention can automatically move under no worker monitor, has reduced experimenter's workload, and simple to operate, and efficiency is high.
