Abstract
The invention relates to an air-tightness detecting device of the body of an accordion. The air-tightness detecting device is characterized by comprising an air source, air supplied by the air source enters a pipeline after input pressure of the air is regulated through a manually-operated pressure change device, the other end of the pipeline is connected with a first flexible pipe, the tail end of the first flexible pipe is connected with the tested accordion through an air inlet hole joint, an air outlet hole joint of the tested accordion is connected with a second flexible pipe, an input air pressure gauge is connected with the position, close to an air inlet hole of the tested accordion, of the tail end of the first flexible pipe, and an output air pressure gauge is connected with the position, close to an air outlet hole of the tested accordion, of the front end of the second flexible pipe. According to the air-tightness detecting device of the body of the accordion, the air pressure displayed on the input air pressure gauge is regulated to 6000+/-20Pa through the manually-operated pressure change device, then whether the read value of the output air pressure gauge is greater than or equal to 580Pa is observed, and therefore whether the air-tightness of the tested accordion is qualified is determined. Besides, the air leakage value of the tested accordion can be measured accurately, and therefore the quality of the accordion can be judged.
Description
Technical field
The present invention relates to a kind of air-tightness detection device of accordion body, for accordion body impermeability is detected, belong to the musical instrument technical field.
Background technology
It is wide that accordion has tone, changes abundantly, can simulate various tone colors, easily-learned easily mastered, and the characteristics such as volume is little, easy to carry, therefore, accordion is well suited for player's self-recreation of all ages and classes, also can be carried to very easily school, the arenas participation is performed.Accordion pronunciation is the pressure that produces air pressure and air-flow during by player's push-and-pull bellows, makes reed vibrates send sound equipment.For improving the quality of accordion, need to when making, guarantee that the impermeability of accordion have relatively high expectations, thereby just can guarantee to send the tone color of accurate grace.
Therefore impermeability is the accordion key technical index, and Chinese accordion product was all with sense organ, to judge by rule of thumb to bubble-tight detection in the past, and for example the pull-up bellows are seen the sagging speed of closing up of bellows, can only qualitatively fail quantitatively to detect the accordion impermeability.A kind of simple to operate and method of accurately reading numerical value is not also arranged at present, therefore neither one criterion value when whether the whole impermeability of identifying an accordion is qualified, also to the consumer, when choosing qin, can't judge exactly that whether whole impermeability is qualified, and whether the impermeability of accordion meets the data value of player's gas consumption playing skill demand simultaneously.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of testing process convenient light and handy, function realizes simple and practical, and does not destroy the air-tightness detection device of the accordion body of product structure.
The object of the present invention is achieved like this:
The air-tightness detection device of accordion body of the present invention, comprise source of the gas, the gas that source of the gas provides passes into pipeline after regulating input pressure by the Manual voltage-transformation device, the other end of described pipeline is connected to the first flexible pipe, the end of the first flexible pipe joins by air admission hole joint and tested accordion, the venthole joint of described tested accordion is connected with the second flexible pipe, described the first flexible pipe rear end is connected to the input air pressure table near tested accordion air inlet position, and the second flexible pipe front end is connected to the output pressure table near tested accordion venthole place.
Described input air pressure table and output pressure table are numerical value formula tensimeter, and manometric precision is handkerchief.
The caliber of described pipeline is 6mm, and the first flexible pipe rear end is 2mm near the caliber of tested accordion air inlet position, and the second flexible pipe is 2mm near the caliber of tested accordion venthole joint.
Described source of the gas is vacuum air pump.
The air-tightness detection device of accordion body of the present invention has the following advantages:
The air-tightness detection device of accordion body of the present invention is transferred to 6000 ± 20Pa by adjusting the Manual voltage-transformation device by the air pressure shown on the input air pressure table, the reading of observing subsequently the output pressure table whether >=580Pa, thereby whether the impermeability that draws tested accordion is qualified, and can accurately measure its gas leakage value, and then can judge the quality of accordion.
The accompanying drawing explanation
The structural representation of the air-tightness detection device that Fig. 1 is accordion body of the present invention.
In figure: source of the gas 1, Manual voltage-transformation device 2, pipeline 3, the first flexible pipe 4, tested accordion 5, the second flexible pipe 6, input air pressure table 7, output pressure table 8.
Embodiment
Referring to Fig. 1, invention relates to a kind of air-tightness detection device of accordion body, comprise source of the gas 1, described source of the gas 1 provides the source of the gas with certain pressure to subsequent detection, normal is vacuum air pump, the gas that source of the gas 1 provides passes into pipeline 3 after regulating input pressure by Manual voltage-transformation device 2, the other end of described pipeline 3 is connected to the first flexible pipe 4, the end of the first flexible pipe 4 joins by air admission hole joint and tested accordion 5, due to caliber too conference cause air pressure too little, too little meeting causes flow inadequate, therefore the caliber of pipeline 3 is 6mm, the first flexible pipe 4 rear ends are 2mm near the caliber of air admission hole joint, the venthole joint of described tested accordion 5 is connected with the second flexible pipe 6, by second pipe 6, pick out, the second flexible pipe 6 is 2mm near the caliber of tested accordion 5 venthole joints, described the first flexible pipe 4 rear ends are connected to input air pressure table 7 near tested accordion 5 air inlet positions, the second flexible pipe 6 front ends are connected to output pressure table 8 near tested accordion 5 venthole places, described input air pressure table 7 and output pressure table 8 are numerical value formula tensimeter, while having avoided using pointer pressure, pointer rocks always in the past, problem that can't accurate reading, and manometric precision is handkerchief, can be measured exactly.
While measuring the impermeability of accordion, by adjusting Manual voltage-transformation device 2, the air pressure shown on input air pressure table 7 is transferred to 6000 ± 20Pa, the reading of observing subsequently output pressure table 8 whether >=580Pa, thereby whether the impermeability that draws tested accordion 5 is qualified, and can accurately measure its gas leakage value, and then can judge the quality of accordion.
