Description
Technical field
The utility model belongs to electric power special-purpose gas chromatograph sample detection parts, is specifically related to electric power special-purpose gas chromatograph part field.
Background technology
In electric system special-purpose gas chromatograph, chromatographic workstation needs to know that the gas sampling moment could start correct sampling period, so just can judge type and the content of various gas.After operator uses syringe sampling, must by a device or the current sample introduction of parts prompting chromatograph, after sample introduction, gas is divided into two-way, and a road can detect CH4, C2H4, C2H6, C2H2 gas by FID1 detecting device; Another road detects through TCD detecting device and connects nickel reburner after H2, and in nickel reburner, CO and CO2 changes into CH4 by adding H2, and then is connected to FID2 detecting device, detects CO and CO2 gas.General electric power special-purpose gas chromatograph is all equipped with sample detection parts, what great majority adopted is Reed type structure, pressing spring leaf in syringe top during sample introduction, go to touch chromatographic microswitch with the top of spring leaf again, the actuating of relay is made after microswitch action, switch to TCD detection signal thus sample introduction detected, because chip architecture of the spring design is unreasonable, ambassador's spring leaf of exerting oneself when likely not reaching microswitch or sample introduction enters under the shell fragment of microswitch, cause detection part malfunctioning, thus have influence on chromatograph detect gas normally go out peak.In addition also have a kind of air pressure detection method, the exercise that operator has to pass through the long period could effectively detect.Visible these two kinds of detection method detecting reliabilities above-mentioned are all lower.
Summary of the invention
It is not in place or detect the problems such as insensitive that the purpose of this utility model is to overcome sample detection that existing electric power special-purpose gas chromatograph sample detection parts exist due to unreasonable structure, and the one provided is rational in infrastructure, easy for installation, cheap, the gas chromatograph sampling detection part can promoted the use of in electric system.
The technical solution of the utility model is as follows: gas chromatograph sampling detection part comprises sample detection top board, sample detection top board pillar and sample introduction nut, sample introduction nut, sample detection top board and sample detection top board pillar are connected to form an entirety, the power moved downward by sample detection top board and sample detection top board pillar is applied on sample detection lower platen uniformly, sample detection back-moving spring is placed into above the spring supporting block of injection port, sample detection lower platen is placed on sample detection back-moving spring, sample detection microswitch is fixed on above microswitch support, the spring leaf of sample detection microswitch contacts with below sample detection lower platen.By syringe needle tube pressing sample detection top board during chromatograph sample introduction, sample detection top board drives sample detection top board pillar sample detection lower platen below to be applied to the power moved downward, sample detection lower platen touches the spring leaf of sample detection microswitch when moving downward, the action of sample detection microswitch is connected to circuit and relay block thus obtains sample introduction signal.The area of sample detection top board thin plate is far longer than sample detection microswitch, there will not be due to the unreasonable phenomenon causing chromatograph sample detection component failure of existing sample detection chip architecture of the spring design.
Gas chromatograph sampling detection part as above, wherein, the stainless steel substrates that sample detection top board, sample detection lower platen are 0.5mm by thickness is made, and the riveted joint of sample detection top board has three sample detection top board pillars made of copper.
Gas chromatograph sampling detection part as above, wherein, sample introduction nut is made by aluminum material, has annular knurl technique, and circumferentially to have three angle intervals be the hole of 120 degree for center of circle diameter is 20mm with sample introduction nut center.
Gas chromatograph sampling detection part as above, wherein, the electric component of sample detection is sample detection microswitch.
The utility model tool compared with present technology has the following advantages: reasonable in design, easy for installation, fundamentally overcoming gas chromatograph, to detect sample introduction not in place and detect insensitive situation, substantially increase accuracy and the sensitivity of sample detection, enable gas chromatograph carry out gas detect more accurately and go out peak.

Embodiment
As shown in the figure, sample introduction nut 3 is made up of aluminum material and is had annular knurl technique, convenience hand is dismantled, the screw thread of bottom can be utilized to be installed on injection port, on sample introduction nut 3, there are three holes at upper 120 degree, the interval of same circle (diameter is 20mm), sample detection top board pillar 2 is riveted on sample detection top board 1 respectively by these three holes, the height of the aspect ratio sample introduction nut 3 of sample detection top board pillar 2 is high 5 to 6 millimeters, after placing the required object such as sample introduction pad, sample introduction nut 3 is installed on injection port together with sample detection top board pillar 2 and sample detection top board 1, such sample introduction nut 3, sample detection top board 1 and sample detection top board pillar 2 just form an entirety, because on sample introduction nut 3, the diameter in three holes is greater than the diameter of sample detection top board pillar 2, sample detection top board 1 and sample detection top board pillar 2 can unencumberedly be moved up and down, because these three pillars are equally distributed, can downward power be applied on sample detection lower platen 4 by three pillars uniformly, sample detection lower platen 4 is moved downward stably, and there will not be because power applies uneven, the phenomenon of sample detection lower platen 4 secundly, sample detection microswitch 5 is installed to above microswitch support 8, as sample detection back-moving spring 6 above the spring supporting block 7 spring suitable for height 20mm elastic force being placed into injection port, regulate the shell fragment of sample detection microswitch 5 that the top of this shell fragment is flushed with the height of sample detection back-moving spring 6 substantially, sample detection lower platen 4 is placed into above sample detection back-moving spring 6, sample detection back-moving spring 6 is utilized to support, now the shell fragment of sample detection microswitch 5 and sample detection back-moving spring 6 are all positioned at the below of sample detection lower platen 4, when sample detection lower platen 4 moves downward 5 to 6 millimeters, the good action of sample detection microswitch 5 can be guaranteed.
Gas chromatograph sampling detection part specific operation process is as follows: extract 1mL gas to be measured with syringe, during sample introduction, syringe penetrates in injection port, and take advantage of a situation and move downward, sample detection top board 1 is pressed downwards with syringe needle tube, then sample detection lower platen 4 is below driven to move downward equally by sample detection top board pillar 2, when after the shell fragment touching sample detection microswitch 5, chromatograph obtains sample introduction signal, TCD detecting device will be outputted to and notify chromatograph workstation sample introduction, a sense cycle can be started.After sample introduction terminates, owing to not having the pressing of syringe needle tube, sample detection back-moving spring 6 moves upward, and whole sample detection modular construction is returned to original state, waits for sample introduction cycleoperation next time.
The utility model greatly improve gas chromatograph sampling detect time accuracy and sensitivity, what solve that sample detection parts in prior art exist can't detect position, causes detection part malfunctioning and adopt the problems such as the complex operation that exists during pneumatic process sample detection, greatly improve work efficiency, and make simple, cheap, can generally promote the use of in electric system.
