Embodiment
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, accompanying drawing will be compareed below
Illustrate specific embodiment of the present utility model.It should be evident that drawings in the following description are only of the present utility model one
A little embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these
Accompanying drawing obtains other accompanying drawings, and obtains other embodiments.To make simplified form, only schematically showing in each figure
The part related to the utility model, they do not represent its practical structures as product.
The applicant is in the production of product and it was found that, under haze weather, the fluorine type gas based on ionization principle
Quantitative leak detector in sensor radix decline quickly, and under the excellent environment of air quality, radix decline it is relatively slow, because
This, applicant is considered, because haze either micro- dust microparticle plugs valve inside, to cause the decline of charge flow rate, cause
The raising of vacuum, the decline of radix.
On this basis, the applicant for solve under without fluorine type gas environment in leak detector sensor radix decline compared with
The problem of fast, attempted following methods：
Method one：Forward direction is blown, and being directed at valve inside position using pressure-air carries out periodicity injection, discovery sensor
Radix rises at once, but the test benchmark flown up for radix of vacuum can not determine, particularly continuously detect
Under environment, can not determine fluorine type gas whether there is and the actual concentrations of fluorine type gas in the case of, the test number of fracture
According to be cannot be received；
Method two：Reversely blow, effect is identical with positive air blowing.
Method three：Control flow quantifies, and adjusts due to the decline of charge flow rate caused by haze or micro- dust, ensures stream
The stabilization of amount, but this method is feasible in theory, but the problem of due to price and size, can not be actually used.
Method four：Using the air of the filter element filtering entrance of PM1.0~2.5, this inspiration comes from a PM2.5 air-conditionings filter
The effect lecture experiment of core, in the cuboid chest that a lucite is made, top is a piece of PM2.5 filter cottons, and bottom is
One small-sized scavenger fan, outwards exhaust, when fan does not work, haze table test value reaches more than 120, after blower fan is opened, haze
Table show value rapid decrease.
In order to which whether verification method four is to solve the effective ways that radix declines, applicant is by a piece of PM2.5 filter cottons bag
Prick in fluorine type gas quantitative leak detector detector air inlet, tightened with rubber band, tested by lasting 3 hours, find this method
The decline of radix can effectively be controlled.And through haze sky and air quality it is excellent in the case of, multiple repetition test, verify this method energy
The effectively decline of control radix
