Abstract
The utility model belongs to the light industry field, which is used for the measurement of gas permeation rate of plastic film. A non-mercury liquid manometer is used to replace a low-pressure end mercury U shape gauge. The height difference of the liquid of the non-mercury liquid manometer is measured by a luminous source, a light sensitive element and a relevant circuit. The utility model has the advantages of no pollution, high precision.
Description
The utility model belongs to field of light industry.
As shown in Figure 1, there is a kind of gas permeation rate determinator (to do institute referring to the smart mechanism in day intrinsic safety field: gas permeation rate determinator instructions), it is used for the test of plastic sheeting permeability, is made up of mechanical pump 1, solenoid valve 2, rotation dream third constellations meter 3, reversal valve 4, source of the gas 5, micrometering valve 6, high-pressure side mercury U-shaped meter 7, high end valve 8, sample chamber 9, low pressure end mercury U-shaped meter 10 and low end valve 11.This device major defect is to have mercury pollution.
Fundamental purpose of the present utility model is to solve the mercury pollution problem.
This device as shown in Figure 2.Its principle of work is: the sample sample chamber 9 of packing into earlier, start mechanical pump 1 then, and open solenoid valve 2, reversal valve 4, high end valve 8, stop valve 17 and low end valve 11 successively, mechanical pump is simultaneously to height pressure side bleed (low vacuum meter 12 indication mechanical pump vacuum tightnesss).After a period of time, close low end valve 11, stop valve 17, reversal valve 4, regulate micrometering valve 6, make high-pressure side be charged to 1 atmospheric pressure (source of the gas 5 provides test gas, high-pressure side tensimeter 13 indication sample high-pressure side pressure).Like this, high-pressure side gas will be penetrated into low pressure end by sample.Low pressure end pressure will rise in time, and the non-mercury solution body of low pressure end pressure gauge 14 will reflect that pressure changes.Gas permeation rate is directly proportional with the pressure climbing speed, measures low pressure end pressure climbing speed and has also just tried to achieve the air penetrability of sample.
The utility model and existing apparatus difference are that this device replaces the rotation dream third constellations to count 3 in low vacuum 12, replaces high-pressure side mercury U-shaped 7 in high-pressure side tensimeter 13, replaces low pressure end mercury U-shaped 10 in the non-mercury solution body of low pressure end pressure gauge 14.
The non-mercury solution body of low pressure end pressure gauge 14 its structures are made up of non-mercury solution body 15, glass bulb 16, stop valve 17, light source 18, light activated element 19, electronic circuit 20 and printer 21 as shown in Figure 3.This pressure gauge is measured liquid height by light source 18 and light activated element 19.Light activated element or blocked light by liquid, or do not blocked light by liquid, light activated element promptly has different photocurrent output, and then realizes data presentation and printings by electronic circuit 20 and printer 21.As need not automatic record, the non-mercury solution body of low pressure end pressure gauge 14 can be reduced to by non-mercury solution body 15, glass bulb 16 and stop valve 17 to be formed.
Because liquid manometer is one of the highest device of pressure measurement accuracy, and opto-electronic conversion can directly be exported digitized signal, has avoided drift, so the utility model measurement stability and precision are all very high.This device is without mercury, and pollution problem has not just existed yet.
Description of drawings:
In the actual device for recording 3 groups of data simultaneously, so 3 groups of high-pressure side tensimeters are arranged, 3 groups of low pressure end non-mercury solution body pressure gauges and 3 groups of sample chambers, 3 groups of low end valves and high end valve.
Electronic circuit 20 can directly be used digital display circuit, also can pass through interface, inserts microcomputer.
The non-mercury solution body 15 general pumping fluids that use.
