Abstract
The invention discloses a one-touch starting device of a chromatographic instrument, and belongs to the technical field of analytical testing instruments. A plurality of small direct-current duplex relays are connected in parallel, and the two normally-open ends of each relay are connected with a two-core rapid-insertion terminal for being connected with two starting wires with various functions; a diode is connected with coils of the small direct-current duplex relays in parallel and serves as a follow current tube protection relay, and the positive electrode of the diode is connected with the negative terminal of a power source; a two-core line bank is used for being connected with the direct-current power source; the devices are welded to a manufactured circuit board with four fixing holes; a one-touch starting button is connected to the positive terminal of the direct-current power source. Simultaneous starting of various required functions of the chromatographic instrument is achieved, the reproducibility of various kinds of analytic data is guaranteed, and the aim is achieved only by pressing one button, so that operation becomes easy, and the economical effect and the practical effect are achieved.
Description
Technical field
The invention belongs to analytical and testing instrument technical field, relate to chromatograph and start the one-key start dress of correlation function or equipment simultaneously
Install meter.
Background technology
When analyzing with chromatograph, in order to ensure the repeatability of various analytical data, it is desirable to various functions start simultaneously.Currently
Chromatograph, either gas chromatograph or chromatograph of liquid, be mostly when sample introduction, go quickly to be respectively started journey
Sequence intensification, external event 1, external event 2, external event 3, work station passage 1, work station passage 2, work station passage 3
Deng, owing to the action of people is unable to reach highly consistent every time, result in the poor reproducibility of analytical data.
Summary of the invention
The present invention provides a kind of chromatograph one-key start device, it is characterized in that: use several small-sized DC duplex relay in parallel,
The two ends of each relay normally open connect the two fast insertion terminals of core, for connecing two startup lines of various function；One diode is also
Being associated on the coil of small-sized DC duplex relay, as continued flow tube protective relay, the positive pole of diode connects power supply negative terminal；One
Only two core line banks, for connecing DC source；Above device is welded on the circuit board of four fixing holes of band made；Directly
Stream power positive end one one-key start button of series connection.
Beneficial effects of the present invention: needed for solving chromatograph, various functions start simultaneously, it is ensured that the reproduction of various analytical data
Property, it is only necessary to pressing a key, just reached above-mentioned purpose, make that operation becomes is very simple, economical and practical.

Detailed description of the invention
Detailed description of the invention is, uses some small-sized DC duplex relays: relay 1 (5), relay 2 (7) ... relay
Device n (8) and some two fast insertion terminals of core: two core fast insertion terminal AN (12), the two fast insertion terminals of core 11 (13), two cores are inserted soon
Terminal 12 (14), the two fast insertion terminal of core 21 (15), the two fast insertion terminal of core 22 (16) ... two core fast insertion terminal n1 (18), two
Core fast insertion terminal n2 (19) and two core line banks (3), be welded to four, the band according to line shown in accompanying drawing is made and fix
On the circuit board (17) in hole (9)；Receive on two core line banks (3) with an end of red-black two-conductor line, red line (2) connect "+"
Black line (1) connects "-", and the other end is received on the DC source that chromatographic and small-sized DC duplex relay nominal value is consistent,
Red line (2) connects positive pole, and black line (1) connects negative pole；It is coupled with one-key start button (10) with one end of two bursts of wires (11)
Two terminals on, the other end is inserted in two plug wire holes of two core fast insertion terminal AN (12) respectively.With a diode (4)
Being connected in parallel on the coil (6) of relay, as continued flow tube protective relay, the positive pole of diode (4) connects power supply negative terminal.Will
Need two terminals of the function key simultaneously started, be connected respectively to corresponding two cores and exempt to connect fast insertion terminal.Select according to needs
n.Its work process, presses one-key start button (10), all relay powers, and its normally opened end closes, two be attached thereto
Institute's connection function on the fast insertion terminal of core is just activated；Unclamping one-key start button (10), all relay power-off, its normally opened end breaks
Opening, the start end of the institute's connection function on the two fast insertion terminals of core being attached thereto also disconnects, and returns to wait starting state next time.
