Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Structure of the present utility model sees that above-mentioned Fig. 1 is to shown in Figure 3.Alarming Concentration adjuster of inflammable gas detector of the present utility model is a kind of device of complete environment-friendly type.This device is made up of three parts: one, air supply system; Two, gas concentration proportioner; Three, detection system.Above-mentioned air supply system is seen Fig. 1.
Air supply system by: two of inflammable gas air supply system and pure air air supply systems part is formed;
1, the inflammable gas air supply system is the cover air supply system of control automatically, it by: source of the gas 1 is bottled combustible gas, reduction valve 2, automatically the control inflammable gas is demarcated the gas concentration controller 3 of concentration and the gas valve opening/closing device 4 that matches with the gas concentration controller, gas cylinder operation valve 5 reaches the inflammable gas air supply system that gas detector 6 is formed; This system is connected by the gas admittance valve 7 of pipeline with gas concentration proportioner 12 bottoms; When the combustable gas concentration in the gas concentration proportioner 12 is lower than calibration value, the gas detector 6 that is contained in the gas concentration proportioner 11 can be transferred to the power supply that gas concentration controller 3 gas concentration controllers can be opened air valve opening/closing device 4 voluntarily with signal, and the air valve opening/closing device then can be opened gas cylinder operation valve 5 automatically; This moment source of the gas 1 through pipeline and gas admittance valve 7 to gas concentration proportioner 12 air feed, increase along with air demand, then the gas concentration in the gas concentration proportioner 12 also can increase, when combustable gas concentration rose to certain value, the gas detector 6 that is connected on the gas concentration controller 3 can give gas dense the information transmission that detects again
Degree controller 3 gas concentration controller this moment then can conducting air valve opening/closing device 4 powered-down, cut off source of the gas so the air valve opening/closing device has been closed gas cylinder operation valve 5, so periodic duty remains in the scope of calibration value gas concentration.
2, the air gas supply assembly by: the non-return valve 10 that has the wet compressor 8 of regulating filter cleaner of the air universe, pressure control table 9, the unidirectional air inlet of air is formed.When the combustable gas concentration in the gas concentration proportioner is higher than demarcation concentration, the dense controller 3 of gas can be opened the compressor 8 that has the wet adjusting of air universe filter cleaner voluntarily and charge into air in gas concentration proportioner 12, to reduce combustable gas concentration, only demarcate concentration until reaching.When the air pressure of gas concentration proportioner 12 was lower than nominal air pressure, pressure control table 9 can be opened air compressor 8 automatically and supply with pure airs to gas concentration proportioner 12 and decide air pressure until up to standard.Above-described air supply system is to realize gas concentration demarcation and the constant purpose of air pressure by the internal circuit of gas concentration controller 3 by the Push And Release of way of contrast control air valve opening/closing device 4 and compressor.
Above-mentioned gas concentration proportioner 12 is containers 11 of a sealing, it and lid 13 phase compositions; Several bolts 14 of lid 13 usefulness fix with the cylindrical shell of gas concentration proportioner, a round pipe mixed flow tube 15 shorter slightly than body seal container is housed in its centre, there are several rounds the pipe upper end, and it fixes with lid 13, and fundamental purpose plays water conservancy diversion and mixed flow effect; A motor 16 is equipped with in the outside of lid, and the shaft extension of motor enters the center of mixed flow tube 15, on the axle fan blade 17 is housed and mainly plays inflammable gas and air mixed flow diluting effect.An air outlet valve 18 is equipped with in the middle and upper part of container, on the lid 13 a pressure control table 9 and a non-return valve 10 is housed;
The effect of gas concentration proportioner 12 is to produce and store the inflammable gas of demarcating concentration, its principle of work is seen Fig. 2, wherein mixed flow tube 15 roles are that the high concentration inflammable gas that makes to be come in by gas admittance valve 7 from container 11 bottoms impacts mutually with the gas of mixed flow tube 15 outlets and forms mixing, then the gas that mixes of this stock-traders' know-how along chamber wall by severals rounds of mixed flow tube circumference with crossing from the air of compressor efferent duct after mix again, fully be mixed into the demarcation concentration gases of detection usefulness then once more through fan blade 17 twists.This mixed flow tube 15 in not too big container, can save need not because be enough to make inflammable gas and air mixed even by the twist of fan.
Above-mentioned detection system is seen Fig. 1.
It is by divider 19, the tester 20 of combustable gas concentration and 21 compositions of debugging pen; Divider 19 is hose couplings of a plurality of interfaces, is connecting the tester 20 and the debugging pen 21 of combustable gas concentration on it, can show the reading and the gas type of direct combustable gas concentration on the panel of tester.
Debugging pen 21 is specifically referring to Fig. 3, and this debugging pen is made up of penholder 22, pen point casing 24, piston 23, spring 25, adapter sleeve 26, hose adapter 27, clamping cap 28 and big small sealing ring 29,30 and 31,32,33 of gasket seals.
The principle of work of debugging pen: referring to the inflammable gas of Fig. 1 from the demarcation concentration of gas concentration proportioner 12, see Fig. 3 by divider 19, the afterbody hose adapter 27 that connects flexible pipe and debugging pen enters in the debugging pen, so the inflammable gas of the demarcation concentration of certain pressure has been arranged on the debugging pen.As long as the gas sensor 34 that will debug this moment on the tested combustible gas probe of a perpendicular alignmnet inserts, piston 23 on the debugging pen promptly is opened, promptly enter on the gas sensor 34 so demarcate the inflammable gas of concentration, this moment, the commissioning staff was that variable resistor on the scalable combustible gas probe makes it just on the value of alarm set point.Debugging pen is in working order the time, and the gas sensor because the O-ring seal 29 on the pen point casing 24 is linking closely is so inflammable gas is can be to external leakage.
Mention the debugging pen after debugging finishes, piston 23 is closed under the effect of spring compression and tension immediately, is close to flange in the pen point casing 24 because of a rubber seal 29 is arranged on the piston 23, so inflammable gas just can not be to external leakage.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
