Abstract
Plastic cement float bowl-type spirometer of the invention is a kind of instrument of positive displacement static measurement gas volume.The instrument air inlet and exhaust share a pipe, eliminate the air vent valve being arranged on former spirometer keg float top.Not only resource, but also the hidden danger without keg float gas leakage have been saved.The outer barrel of former float bowl-type spirometer is made of metal, and by more than ten of components through multi-step process such as aperture, welding, riveting, fastenings, just outer barrel and air inlet pipe and stabilizer blade are combined into one.It expends a large amount of manpower, material resources and financial resources and just completes the production process.Outer barrel bucket bottom of the invention raises upward to form the rotary table (body) of hollow no bottom surface, disengaging tracheae and stabilizer blade is easily combined together with outer barrel, by being molded one-pass molding.A large amount of manpower and material resources are saved, corrosion is avoided, convenient for keeping, service life is extended, reduces water injection rate when use.Spirometer of the invention can also be used for the biogas metering of anaerobic digestion test.
Description
Technical field
The present invention relates to a kind of instruments of positive displacement static measurement gas volume.
Background technique
Before last century the nineties, float bowl-type spirometer is also commonly used, its outer barrel and air inlet pipe and stabilizer blade is all
It is made of metal, production is relatively complicated, and price is higher, and easy the disadvantages of getting rusty, gradually replaced electronic meter for vital capacity.But electricity
Sub- spirometer there are the problem of it is quite a few, for example price is higher, and metering is inaccurate, unstable, can not visually judge the accurate of metering
The problems such as property.So that nowadays many physical examination mechanisms are all not provided with the measurement of lung capacity.Or float bowl-type spirometer is more intuitive more
Reliable measurement lung capacity.It is high that the present invention specifically addresses spirometer prices, and unstable etc. ask is measured in inconvenient keeping of easily getting rusty
Topic.
Summary of the invention
The present invention replaces the manufacture of all metal parts on float bowl-type spirometer with plastics, and removes keg float top vent from
The setting of valve.Reach simplified production process, cost is reduced, and avoid corroding, convenient for the purpose of preservation.
Spirometer of the invention is made of keg float, outer barrel, emulsion tube, blow gun, and air vent valve is not set on keg float top, exhaust
A pipe is shared with air inlet.Outer barrel bucket bottom raises upward to form the rotary table of hollow no bottom surface, and disengaging tracheae passes perpendicularly through circle
Platform upper bottom surface, outer barrel and disengaging tracheae and stabilizer blade integrated injection molding.
It is an advantage of the invention that metal is replaced with plastics, and by the deformation of outer barrel, disengaging tracheae and stabilizer blade and outside
Bucket is combined into one, and realizes single injection-molded, considerably reduces cost, also reduce water injection rate when use.
Detailed description of the invention
Fig. 1 is the sectional view of plastic cement float bowl-type spirometer.
Specific embodiment
The embodiment of plastic cement float bowl-type spirometer is described in detail below with reference to Fig. 1.
The first step, it is first determined the range of spirometer is 10 liters.
Second step determines the size of keg float [1]: internal diameter 210mm according to its range；The bucket high 356mm of cylinder, bucket wall thickness 2mm, no
If air vent valve.The size of outer barrel [2]: internal diameter 218mm, the high 360mm of bucket cylinder, the circle of the hollow no bottom surface of bucket bottom protrusion are determined again
Platform [3], the bottom surface diameter 198mm of rotary table, upper bottom surface [5] diameter 138mm, rotary table [3] high 312mm；In enterprising escape pipe [4]
Diameter 9mm, high 44mm, thickness of pipe wall 5mm；Lower disengaging tracheae [6] internal diameter 9mm, long 40mm, thickness of pipe wall 2mm；Stabilizer blade [7] diameter 16mm,
High 33mm, totally 3.
Third step, the size according to keg float [1], outer barrel [2] separately design production injection mold.Then with the mold made
Injection molding production keg float [1] and outer barrel [2] respectively.And metering scale is marked on keg float [1].
4th step mixes a root long 60cm, 9 × 12 emulsion tubes [9] and several blow guns [8], the plastic cement of complete set
Float bowl-type spirometer completes.
The application method of plastic cement float bowl-type spirometer
1. keg float and outer barrel are separated, one end of emulsion tube is set on lower disengaging tracheae, the other end puts on blow gun, will be outer
Bucket is by keeping steady on table top.
2. in the clear water injection outer barrel being close with room temperature by preprepared, make the water surface flood rotary table upper bottom surface 1~
2cm, or away from edge about 2cm in outer barrel.
3. adjusting the verticality of (with the padded partially short stabilizer blade such as thick paper) exterior bowl and horizontal plane.
4. keg float is pressed into water slowly, it is pressed onto outer barrel bottom always.
5. subject holds blowing nozzle, for deep air-breathing of standing to greatest extent, mouth is close to blowing nozzle, blows slowly into bucket
Gas until cut-off cannot blow again, by emulsion tube doubling or blocks, and reads the number for carving table in outer barrel along the keg float of horizontal position
Word, the as lung capacity value of subject.
6. resetting: unclamping emulsion tube, keg float is pressed into water slowly, until outer barrel bottom.
This instrument can also be used for the biogas metering of anaerobic digestion test.
Claims (4)
