The ten-way valve has higher cost, and is more beneficial to the development of enterprises if the ten-way valve can be replaced by a valve body with lower cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a non-A total hydrocarbon on-line chromatograph of one way carrier gas six-way valve to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a non-first total hydrocarbon on-line chromatograph of single channel carrier gas six-way valve, includes chromatographic column, the hydrogen flame detector of being connected with the chromatographic column and the air compressor machine of being connected with the upper tube of hydrogen flame detector, the chromatographic column is connected with the valve body through total hydrocarbon column, and the valve body is connected with sample gas import and sample gas export respectively, sample gas access connection needle type valve, and the other end and the valve body of needle type valve are connected.
The valve body is a six-way valve, the chromatographic column is connected with a methane column, the methane column is connected to the total hydrocarbon column, and the valve body is provided with a quantitative ring.
Preferably, the air outlet end of the needle valve is connected with the air outlet end of the air compressor.
Preferably, the methane column is connected to the total hydrocarbon column by a three-way valve.
Compared with the prior art, the beneficial effects of the utility model are that:
1. compared with the original ten-way valve, the six-way valve is adopted, so that the cost is greatly reduced, the development of enterprises is facilitated, the maintenance and the operation are convenient, the peak output is fast, and the reproducibility is good;
2. the prior art is that total hydrocarbon column flow and methane column flow are controlled with two valves respectively, increase material cost undoubtedly like this to must the flow control the same can go out the peak sharp-pointed (peak sharp-pointed in the chromatogram, reproducibility is good), and this design realizes that two tunnel flows are controlled simultaneously to a valve, uses independently.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2, the utility model provides a technical solution of a one-way carrier gas six-way valve on-line chromatograph for non-A total hydrocarbons: the utility model provides a non-first total hydrocarbon on-line chromatograph of single channel carrier gas six-way valve, includes chromatographic column 1, the hydrogen flame detector 11 of being connected with chromatographic column 1 and the air compressor machine of being connected with the upper tube of hydrogen flame detector 11, and chromatographic column 1 is connected with valve body 2 through total hydrocarbon post, and valve body 2 is connected with sample gas inlet and sample gas outlet respectively, and sample gas inlet connects needle type valve 12, and the other end and the valve body 2 of needle type valve 12 are connected.
The valve body 2 is a six-way valve, the chromatographic column 1 is connected with a methane column, the methane column is connected with a total hydrocarbon column, the methane column is connected with the total hydrocarbon column through a three-way valve and is convenient to connect, the valve body 2 is provided with a quantitative ring 21, compared with the original two, one quantitative ring 21 is less, because the innovative method uses a special chromatographic column and air resistance, the total hydrocarbon and the methane column use the same carrier gas, one double quantitative ring equally distributes air inflow, the total hydrocarbon and the methane are well separated, the test effect is not influenced, thus, one quantitative ring is effectively saved, two connecting ports are saved on the valve body 2, meanwhile, the methane column is connected with the total hydrocarbon column, one connecting port is saved, a pressure regulating valve connected with a needle valve 12 is also arranged, the pressure regulating valve is originally connected with the valve body 2 and is also saved at present, thus four connecting ports are saved, and the six-way valve can be satisfied, compared with a ten-way valve, the cost is reduced, and the air outlet end of the needle valve 12 is connected with the air outlet end of the air compressor.
The working principle is as follows: the chromatographic column 1 and the needle valve 12 are used, the same carrier gas is used for the total hydrocarbon column and the methane column, the double quantitative ring 21 is used, the gas resistance of the gas circuit of the methane column is the same as that of the gas circuit of the total hydrocarbon column, the gas inlet pressure is the same as that of the gas outlet pressure, the gas flow rate of the column is the same, and therefore the gas inlet amount is evenly distributed, the total hydrocarbon and the methane are well separated, the testing effect is not influenced, parts are saved, and the cost is reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
