Pressure sensor adopts the dibit electro connecting pressure gauge, and (normally closed contact is identical with the pressure that open contact is set, and promptly at same position, and can show the pressure signal of force value, sensing and be convenient to the pressure setting.
Be provided with pressure stabilizing cavity (omitting among the figure) in the gas pipe line between charge valve and the inflation object, the pressure responsive element of pressure sensor is communicated in this pressure stabilizing cavity, and promptly pressure sensor is directly responded to the pressure in the pressure stabilizing cavity.Know easily that by Hydrodynamics Theory (Bernou1li equation) at same ducted arbitrary section fluid, pressure P * flow velocity V=constant R that is to say that rate of flow of fluid high more its pressure in somewhere is just low more in the pipeline.Because the force value that device for pressure measurement detects is the fluid flow pressure value, so inevitable force value (force value of detection) and its deviation greater than actual set of the actual pressure behind its steady pressure (static pressure) increases with the increase of flow velocity.To this; Consider on the one hand the regularly relation that is directly proportional with exhaust source (being inflated object) pressure of (throttle valve adjustment) combustion gas flow speed of exhausr port size one, can slacken even eliminate the error that above-mentioned phenomenon produces through experimental adjusting setting equivalence value (pairing dynamic equivalent pressure set points when the static pressure that exhaust source is vented to certain a moment equals target pressure value); On the other hand; By fluid mass conservation theorem (continuity theorem): the quality that flows through arbitrary cross section in the same pipeline in the unit time equates; That is to say; Flow rate of fluid is just low more more greatly so here for the equivalent diameter in arbitrary cross section in the pipeline, and therefore setting up pressure stabilizing cavity at the pressure measurement point place slackens the error that actual measurement produces.
Because inflation all is step with venting in the design of batch (-type) self-filler; That is to say; Measured pressure all is the problem that there is not measured deviation in actual pressure (static pressure), but because its venting is step, therefore; Certainly existed the shortcoming of venting (actual pressure value is less than setting value), the frequent closed and disconnected in contact (vibration) that will inevitably the build-up of pressure measurement mechanism thus cause the too fast oxidation in contact and damage.On the one hand can be through reducing exhaust velocity and reducing the setting value of detection time and slacken; On the other hand, the pressure set points of heightening measurement mechanism (actual required force value is slightly smaller than the actual set force value) that also can be according to circumstances suitable is controlled.
Fig. 2 is the circuit arragement of the utility model batch (-type) self-filler; The KT of slug relay that wherein circulates has adopted has the JSS48A-S type circulation slug relay that (closure) function is broken off in time closing (disconnection) time-delay, and its circulation time-delay mode is: set time period and the time of the first setting-up time T1 and the second setting-up time T2 earlier, the energising back first setting-up time T1 trigger; The right double figures sign indicating number pipe showed for the first setting-up time T1 time; The KT of circulation slug relay is failure to actuate, when the first setting-up time T1 reaches settings, and the KT of circulation slug relay adhesive; The right double figures sign indicating number pipe blanking; The second setting-up time T2 trigger, left side double figures sign indicating number pipe show that the circulation KT of slug relay discharges charactron blanking simultaneously when the second setting-up time T2 reaches settings; The first setting-up time T1 is trigger again, and the circulation time-delay goes round and begins again.
Signal risk phenomenon that control device produces because of the mechanical action hysteresis quality can be eliminated (after once inflation finishes by circulation slug relay; Can air pressure generation fluctuation can not stablize immediately owing to being inflated object on the one hand; On the other hand; Again since inflation pressure much larger than setting pressure; Need deflection one segment distance so pointer reaches stable position, and other signals that should not move have moved in these processes, and then have caused the phenomenon of control system job insecurity) also promptly setting (the first setting-up time T1) the short wait time guarantees that mechanical action carries out smoothly.
Among Fig. 2, all consuming parts all are arranged between the two poles, promptly between the A among the figure, the B.

(2) first setting-up time timing finish; The KT of circulation slug relay contacts status switches, and relay K A1, latching circuit KA1 connect relay K A1 self-locking; Charge valve SV1 and inflation indicator lamp L1 connect; Begin inflation, and, therefore begin the timing of second setting-up time this moment because the first setting-up time timing finishes.
(3) second setting-up time timing finish, and the KT of circulation slug relay contacts status switches, and begins the timing of first setting-up time, in this process, detect the pressure of inflation object through pressure sensor KP.
(4) first setting-up time timing finish, and the KT of circulation slug relay contacts status switches, and after this is divided into two kinds of situation.
First kind of situation is for inflating pressure (the static pressure)＜setting pressure of object, and each contacts status of pressure sensor KP is constant, and relay K A1 connects once more; Charge valve SV1 and inflation indicator lamp L1 connect; Begin inflation, be equivalent to return step (2), until the pressure＞setting pressure of inflation object.
Second kind of situation is for inflating the pressure＞setting pressure of object, at this moment:
(5) each contacts status of pressure sensor KP switches, relay K A1 outage, charge valve SV1 and inflation indicator lamp L1 outage stopping inflation.
Relay K A3 connects, and venting indicator lamp L2 and aie escape valve SV2 connect and begin venting, relay K A2 and latching circuit KA2 outage (making the KT of circulation slug relay power-off restoration) simultaneously.
(6) when venting to the pressure of inflating object＜setting pressure, pressure sensor KP resets, relay K A3 outage; Aie escape valve SV2 stops venting; Because flow pressure is less than static pressure, although this moment, pressure sensor KP resetted, after the pressure stability of inflation object; Can rise slightly and surpass setting pressure, pressure sensor KP is triggered.
(7) relay K A3 connects and self-locking, the KT of circulation slug relay energising, and first setting-up time that picks up counting, aie escape valve SV2 are connected and are begun venting.
(8) first setting-up time timing finish, and the KT of circulation slug relay contacts status switches, and make relay K A3 outage, are equivalent to return step (6), and so the circulation venting is until pressure (the static pressure)＜setting pressure of inflation object.
Comprehensive step (4) two kinds of situation are afterwards finally inflated object by constantly inflation, venting, reach dynamic state of equilibrium, dynamically pressure are remained on setting pressure.
