For this reason, the utility model technical matters to be solved is to provide a kind of pick-up unit of lower-cost demarcation flowerpot permeability.
For solving the problems of the technologies described above; The utility model discloses a kind of device for checking air permeability of flowerpot, and it comprises, packoff; Said packoff has and is suitable for the cavity that basin body to be measured is put into; After said basin body to be measured is put into packoff, packoff is separated into the inner chamber that surrounds with said basin body inwall to be measured, and the exocoel that surrounds with said basin body outer wall to be measured; Gas supply device, said gas supply device is communicated with said inner chamber or exocoel; And being arranged at the detecting unit on the said gas flow that said gas supply device produces, said detecting unit changes in order to the gas that detects through the flowerpot wall.
Said packoff comprises, base, and said base is provided with cavity, and the basin of said basin body to be measured is along being arranged on the inside edge of said cavity; Form said exocoel between said basin body outer wall to be measured and the said cavity inner wall; End cap, said end cap are pressed and are located at said basin body to be measured upper end, and it offers through hole and is communicated with said inner chamber; Said end cap and said base are tightly connected through locking device.
Said gas supply device is communicated with said exocoel through the through hole that is opened on the said base side wall.
Said gas supply device is communicated with said inner chamber through the through hole that is opened in said end cap.
Said gas supply device comprises air compression plant, and the pressure-regulating valve of adjustments of gas pressure.
Said detecting unit comprises, the flowmeter and the tensimeter that are communicated with said gas supply device.
Said detecting unit comprises, the tensimeter that is communicated with said gas supply device, and the interior ball float of through hole that is arranged at said end cap.
Realize being tightly connected through O-ring seal between said base and the said basin body to be measured.
The technique scheme of the utility model is compared prior art and is had the following advantages:
The utility model is used air-locked packoff, behind the flowerpot chamber placed within, is separated into inner chamber and exocoel, and wherein a chamber is communicated with gas supply device, and the gas that gas supply device produces flow into exocoel or inner chamber through tub wall again through inner chamber or exocoel.The pick-up unit that detects basin body gas penetration potential quality is set in this gas flow channel, and it is lower than the prior art cost, and detection accuracy is high.
In order to find out the quality of this flowerpot gas penetration potential intuitively, the detecting unit of this pick-up unit is the ball float that is arranged in the said end cap through hole, and the gas that gets into inner chamber through tub wall can push this ball float when reaching a certain amount of.Therefore, this pick-up unit is directly perceived, simple.
In order to measure the quality of this flowerpot permeability exactly; The detecting unit of this pick-up unit is selected flowmeter and the tensimeter that is communicated with said gas supply device for use; After opening gas supply device; Under certain pressure, can measure the air penetrability of this flowerpot through the reading of flowmeter in the certain hour.
