Abstract
The utility model discloses a multi-component automatic gas distributing instrument. The gas distributing instrument is an instrument for matching various gases as required. The gas distributing instrument is characterized by comprising an electronic flow control device, a gas flow controller, a gas mixing device, a gas way connecting device and a digital signal output device connected in sequence; the gas mixing device includes a five-way gas cavity; one way of the five-way gas cavity is an output channel, and the rest four ways of the five-way gas cavity are input channels. The gas way connecting device consists of stainless steel full-hard sealed clamping sleeves, pipes and stainless steel quick joints. The multi-component automatic gas distribution instrument can dilute high-concentration standard gas, has excellent gas tightness and a simple structure, requires no other external flow controllers, and is convenient to operate.
Description
Technical field
The utility model relates to a kind of distributing instrument, particularly discloses a kind of polycomponent automatic distributing instrument, is applicable to use the sample preparation of calibrating gas in the industries such as each detection, demarcation, analysis.The utility model mixes gas, and has solved the problem that low concentration oxygen and nitrogen are difficult to dilution.
Background technology
The distributing instrument of prior art generally in the time of gas analysis standard gas concentration can not proportioning below 1ppm, the impurity of ppb rank can not directly directly be measured in stratographic analysis on chromatograph; Using when general distributing instrument, because existing instrument gas path joint and gas circuit Guan Buquan are that stainless steel seals firmly, this has increased leakage point.At proportioning ppb level oxygen and nitrogen space-time air-capacitor easy to leak.In the time of distribution, mixing arrangement is easy inhomogeneous and have dead volume, has increased purging difficulty.
Summary of the invention
The purpose of this utility model is to address the deficiencies of the prior art, a kind of polycomponent automatic distributing instrument is provided, adopts computer operation, can diluting high-concentration calibrating gas, solve a difficult problem for ppb level Trace Components analysis Direct Analysis, and overall fully hard sealing and the link of stainless steel gas circuit, impermeability is better, and structure is simpler, reproducible, linear splendid, without other external flow controllers, easy to operate.
The utility model is achieved in that a kind of polycomponent automatic distributing instrument, described distributing instrument is that multiple gases is carried out to the instrument of proportioning as required, it is characterized in that: described distributing instrument comprises the electronic flow control device, gas flow controller, gas mixer, gas circuit connecting device and the digit signal output apparatus that are linked in sequence.Described gas mixer comprises a five-way air cavity, and wherein a road is output channel, and all the other four tunnels are input channel.Described gas circuit connecting device is the fully hard hermetic collar of stainless steel and pipeline and stainless steel rapid-acting coupling.
Described gas flow control device comprises four mass rate control meters.Described gas ratio part flow arrangement comprises flowmeter and needle valve.Described selection digit signal output apparatus comprises that 485 serial ports turn 232 serial converters, and described electronic flow control device comprises the control flow software of four mass flowmeters.
The beneficial effects of the utility model are: the utility model can diluting high-concentration calibrating gas, solve a difficult problem for ppb level Trace Components analysis Direct Analysis, also solve the problem that low concentration oxygen and nitrogen are difficult to dilution, solved mixed gas and mixed and dead volume problem.The utility model adopts fully hard sealing and the link of stainless steel gas circuit, and impermeability is better, and gas mixes more even, structure is simpler, reproducible, linear splendid, digital voltage signal directly output utilizes the each road of computer control flow, without other external flow controllers, easy to operate.
