Technical field
The invention belongs to the survey of gas flow measurement application field, especially low discharge or the leakage rate of micrometeor gas
Amount, number is dripped by the water droplet of discharge, calculates micro leakage rate.
Background technology
In current gas flow measurement, there are vortex-shedding meter, V cone flow meters, Integrative orifice meter, heating type gas
Mass flowmenter, generally it is required for stabilization, continuous and more than certain flow rate and flow air-flow to detect, to low discharge or micro-
The difficulty that test is inaccurate and tests be present in the flow of flow gas.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of gas displacement measurement apparatus.It is right
The gas for needing to test flow accesses this displacement devices, and displacement devices be full of test water, to flowmeter after closing ball valve
Gas is inside filled with, gas flow is calculated according to the water capacity of discharge and drain time.
A kind of gas displacement measurement apparatus, it include container casing, drainpipe, airway tube, soon insert sub- joint, enter water polo
Valve, drainpipe are folding rule shape, including vertical section, horizontal segment and 45 degree of draining sections, the vertical section of drainpipe extend into vessel shell
Nearly bottom A on the left of body；Airway tube includes vertical section, horizontal segment, and the horizontal segment of airway tube is inlet end, with inserting sub- joint phase soon
Connection, the nearly bottom B that the vertical section of airway tube is extend on the right side of container casing, nearly bottom A, B be in same level, distance appearance
The bottom of device housing is 1 centimetre；The bottom at container casing center extends provided with isolation, is diffused into for obstructing gas from airway tube
To drainpipe；Water intake ball valve is located at the top of container casing, for input test water.
The horizontal segment of the drainpipe and the top of container casing are located in same level, basic water for realizing discharge etc.
Volume is in the gas of discharge.

Exactness；
3rd, there is convenience quick for installation, simple and practical, there is larger application value, be easy to marketing.
Brief description of the drawings
Fig. 1 is the structural representation of gas displacement measurement apparatus；
Wherein, 1. container casings, 2. drainpipes, 3. isolation extend, 4. airway tubes, 5. soon insert sub- joint, 6. water intake ball valves.
Embodiment
The utility model is described further below in conjunction with accompanying drawing.
As shown in figure 1, a kind of gas displacement measurement apparatus, it includes container casing 1, drainpipe 2, airway tube 4, fast slotting son
Joint 5, water intake ball valve 6, drainpipe 2 are folding rule shape, including vertical section, horizontal segment and 45 degree of draining sections, drainpipe 2 it is vertical
Section extend into the nearly bottom A in the left side of container casing 1；Airway tube 4 includes vertical section, horizontal segment, and the horizontal segment of airway tube is air inlet
End, it is connected with inserting sub- joint 5 soon, the vertical section of airway tube extend into the nearly bottom B on the right side of container casing 1, at nearly bottom A, B
It it is 1 centimetre apart from the bottom of container casing 1 in same level；The bottom at the center of container casing 1 extends 3 provided with isolation, for hindering
Trapping body diffuses into drainpipe 2 from airway tube 4；Water intake ball valve 6 is located at the top of container casing 1, is used for input test
Water.
The horizontal segment of the drainpipe 2 is located in same level with the top of container casing 1, the basic water for realizing discharge
In equal volume in the gas of discharge.
Described container casing 1 uses transparent material, and side wall is provided with graduation mark.Realization is accurately read in drainage procedure
The water of discharge.
Application Example
Air-flow to be measured is connected to and inserted soon on sub- joint 5, test water is injected into container casing 1 by water intake ball valve 6, directly
Water is discharged to drainpipe 2, when bubble discharge, beginning timing, the body for the test water discharged according to drainpipe 2 occurs in airway tube 4
Product and timing, calculate the throughput of air-flow to be measured.
Air inlet pressure-bearing and draining during discharge capacity are realized in same level in drainpipe 2 and the Xia Kou bottom surfaces of airway tube 4
The lower mouthpiece pressure of pipe is equal, and resistance is consistent, realizes accurate measurement.Isolation extends 3 barrier gases from 4 times mouth discharge diffusions of airway tube, enters
Enter the possibility of 2 times mouths of drainpipe, improve the degree of accuracy of measurement.
