Abstract
The utility model relates to a soap film gas flow measuring instrument for measuring the gas flow, which is composed of an air outlet, a soap film pipe, an air inlet B, an air inlet A, soap solution, a rubber ball, a soap film cutting and taking device and a soap solution pipe, wherein the lower end of the soap film pipe is provided with the soap film cutting and taking device which is extended in the soap solution pipe, and measured gas enters in the soap solution pipe by the air inlet A and the air inlet B. The utility model flows out by the soap film cutting and taking device, the soap film pipe and the air outlet, and deformed soap film can be prevented from generating by producing the soap film in the mode of rubber ball squeezing or other modes. After the soap film moves upwards by the soap film cutting and taking device and enters the soap film pipe, and the flow rate can be determined by measuring with a stop watch or monitoring in photoelectric the time of the soap film which passes through two marking lines or positions of the soap film pipe.
Description
Technical field
The utility model relates to the soap-film gas flow measurement device that a kind of gas flow measurement is used.
Background technology
In the prior art, there is following shortcoming in use in the soap-film gas flow measurement device that gas flow measurement is used: (1) is when the measurement gas flow, when gas stream is crossed the soap-film pipe, sometimes there is the deformity soap-film to produce, the soap-film of deformity is not easy oneself and disappears, and causes gas flow measurement inaccurate, and the soap-film that is generated is not as meeting the requirements, be a soap-film that meets the requirements to take place come metered flow generally speaking again, cause surveying work efficient low.(2) when the gas flow of measuring is big (generalized case greater than 6 liters/minute), it is to be difficult to realize that a desirable soap-film take place, and makes the measurement of gas flow use standard set-up to be subjected to limitation, can not satisfy request for utilization.
The utility model content
The purpose of this utility model is that a kind of soap-film gas flow measurement device will be provided, and to solve a difficult problem of measuring the gas flow more than 6 liters/minute with existing apparatus, the realization gas flow is accurately measured.
The purpose of this utility model is achieved in that soap-film gas flow measurement device of the present utility model comprises: gas outlet 1, soap-film pipe 2, air intake opening A4, soap lye 5, glueballs 6, soap lye pipe 8, it is characterized in that, comprise that also soap-film cutting gets film device 7, the below that film device 7 is positioned at soap-film pipe 2 is got in this soap-film cutting, and stretches in the soap lye pipe 8.
As a kind of improvement of the present utility model, on the sidewall of soap lye pipe 8, be provided with N air intake opening B3, (N=0,1,2,3......n), air intake opening B3 is positioned at the top of air intake opening A4.
The soap-film cutting is got film device and is positioned at soap-film pipe below, stretch in the soap lye pipe, air intake opening A and air intake opening B are arranged on the soap lye pipe, air intake opening B generally is positioned at air intake opening A top, the quantity that has contained air intake opening on the soap lye pipe that the soap-film cutting gets film device is N (N=0,1,2,3......n), how much deciding of its quantity according to the size of tested gas flow, generally, get N=0, when gas flow during greater than 6 liters/minute when gas flow during less than 6 liters/minute, for guaranteeing to produce the soap-film that conforms with measurement requirement, need and will enter the soap lye pipe by air intake opening B from the part of gas outlet effluent air, the air intake opening cross-sectional area that how much depends on air intake opening B of its quantity, tested in other words gas flow is greater than 6 liters/minute portion gas, through air intake opening B, film device is got in the soap-film cutting, enter the soap-film pipe, last, flow out by the gas outlet together with the gas that enters the soap-film pipe from air intake opening A.
The utlity model has following advantage: the cutting of (1) soap-film is got film device and nonstandard soap-film can be cut out a soap-film that conforms with measurement requirement.(2) when by gas flow during greater than 6 liters/minute, most of gas enters the soap-film cutting by air intake opening B and gets film device, and small part gas enters the soap-film cutting by air intake opening A and gets film device, can avoid the soap-film fragmentation, guarantees to generate the soap-film that meets the requirements.Gas enters the soap lye pipe by air intake opening A, air intake opening B, get film device, soap-film pipe, gas outlet outflow through the soap-film cutting, push glueballs (or using other method) then and produce soap-film, when soap-film goes upward to soap-film cutting and gets film device, the soap-film cutting is got film device and is cut out the soap-film that conforms with measurement requirement, up from the gas promotion soap-film that air intake opening A, air intake opening B enter, measure (or photoelectric monitor) soap-film by the time between soap-film pipe two grooves (position) with stopwatch, obtain flow.
The concrete structure of utility model is provided by following example and accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of the utility model soap-film gas flow measurement device.
Embodiment
As shown in Figure 1, in the present embodiment, soap-film gas flow measurement device comprises a gas outlet 1, soap-film pipe 2, air intake opening B3, film device 7 is got in air intake opening A4, soap lye 5, glueballs 6, soap-film cutting, soap lye pipe 8, wherein, gas outlet 1 is positioned at soap-film pipe 2 upper ends, and the soap-film cutting is got film device 7 and is positioned at soap-film pipe 2 lower ends.Gas enters soap lye pipe 8 by air intake opening A4, push glueballs 6 (or using other method) then and produce soap-film, when soap-film goes upward to soap-film cutting and gets film device 7, get film device 7 by the soap-film cutting and cut out the soap-film that conforms with measurement requirement, enter the gas of soap lye pipe 8 from air intake opening A4, air intake opening B3, promote soap-film, move up and measure (or photoelectric monitor) by the time between soap-film pipe 2 liang of groove C, D (position), obtain flow with stopwatch.
When by gas flow during greater than 6 liters/minute, measurement mechanism of the present utility model enters soap-film cutting with most of gas by air intake opening B3 by employing and gets film device, small part gas enters the mode that film device 7 is got in the soap-film cutting by air intake opening A4, avoid the soap-film fragmentation, guarantee to generate the soap-film that meets the requirements.
