Abstract

The utility model discloses an air distribution instrument for an air control test box, which comprises a plurality of air delivery pipes disposed in parallel, a mixer and an exhaust pump. A mass flow controller and a filter are disposed sequentially on each air delivery pipe, an air inlet of the mixer is communicated with one end, with the filter mounted, of each of the air delivery pipes disposed in parallel, and an air inlet of the exhaust pump is connected with an air outlet of the mixer. The mass flow controller is used for measuring flow and mass of air, so that manual reading and conversion are not needed. Further, by the aid of the filter device and the exhaust device, cleanness of air sources is guaranteed, and mixed air sources can more smoothly enter the air control test box through long-distance pipes.

Description

A kind of controlled atmosphere chamber distributing instrument
Technical field
The utility model relates to a kind of distributing instrument, especially, relates to a kind of controlled atmosphere chamber distributing instrument.
Background technology
As everyone knows, if will guarantee the quality of preserving fruit and vegetable utilizing in the air-conditioned cold store, must do the air-conditioned cold store simulated experiment earlier to the fruits and vegetables of different cultivars.From experiment, draw controlled atmosphere parameter value accurately, thereby be that the preserving fruit and vegetable utilizing of storing in the air-conditioned cold store offers suitable parameters.
Yet, adopting glass rotameter in the air-conditioned cold store simulated experiment of the prior art, this is very inconvenient.Main cause is: the flowmeter that prior art is used is demarcated by the air value, also needs to convert when measuring other gases; Secondly, existing flowmeter mainly is applicable to measures big flow gas, then shows not obviously for the variation of minimum gas, is difficult to regulation and control; Once more, the flowmeter of prior art needs manual adjustments, and needs artificially to observe at any time and adjust, thereby cumbersome and inconvenient.
Simultaneously, though the service property (quality) flow controller is also arranged in the prior art, for whole distributing instrument, the technological deficiency that also has other, for example do not have filter, this makes the gas that enters the controlled atmosphere chamber pure clean inadequately, thereby the result of test is exerted an influence.Simultaneously, air extractor is not set between blender and chamber in some distributing instrument, thereby makes the gas in the blender not enter in the chamber glibly by the pipeline of long distance.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of distribution instrument that has filter and air extractor and have mass flow controller is provided.
The utility model discloses a kind of controlled atmosphere chamber distributing instrument, comprising: the gas pipeline that several be arranged in parallel wherein is disposed with mass flow controller and filter on each gas pipeline; Blender, the end that filter is installed of its air inlet and the described gas pipeline that several be arranged in parallel is connected; Aspiration pump, the gas outlet of its air inlet and described blender is connected.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model, described several mass flow controllers also are connected with several display floaters by corresponding signal lines.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model, described several filters are three, and are connected to nitrogen source of the gas, oxygen source and carbon dioxide air source respectively.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model, described several mass flow controllers are three.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model also is respectively arranged with control valve between described several mass flow controllers and described nitrogen source of the gas, oxygen origin and the carbon dioxide air source.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model, described several display floaters are three.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model, the gas outlet of described aspiration pump is connected to and makes the gas point.
Preferably, controlled atmosphere chamber distributing instrument of the present utility model also is provided with control valve between described blender and the described aspiration pump.
The beneficial effects of the utility model are: the utility model adopts mass flow controller to come the flow and the quality of measurement gas, thereby does not need manual read and conversion.Simultaneously, the utility model is provided with filter and air extractor, has guaranteed the cleaning of source of the gas on the one hand once more, on the other hand can be so that mixed source of the gas enters the controlled atmosphere chamber more glibly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, controlled atmosphere chamber distributing instrument of the present utility model comprises three gas pipelines that be arranged in parallel, is respectively oxygen gas pipeline, nitrogen gas pipeline and carbon dioxide gas pipeline.And be disposed with mass flow controller and filter on each gas pipeline.Like this, always have three mass flow controllers, they control the flow of oxygen source, nitrogen source of the gas and carbon dioxide air source in described three gas pipelines of flowing through respectively.Each mass flow controller is connected with display floater by holding wire, so always has the flow that three display floaters show oxygen, nitrogen and the carbon dioxide of each gas pipeline of flowing through respectively.
Distributing instrument of the present utility model also comprises the blender that the end that filter is installed of air inlet and three gas pipelines that be arranged in parallel is connected, and the gas outlet of blender is connected with aspiration pump.Like this, the flow through gas of three gas pipelines just can be pumped to making the gas point via aspiration pump through the effect of blender.
Flow for the ease of control gas also is provided with control valve respectively between oxygen source, nitrogen source of the gas and carbon dioxide air source and three mass flow controllers, just can control the break-make of each road gas like this by these three control valves.And the flow of the mist that comes out from blender for the ease of control also is provided with control valve between aspiration pump and blender.(control valve control break-make, mass flow controller control flow)
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
