Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the electrical schematic diagram of the utility model gas control time controlling a kind of specific embodiment of gas circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of gas control time to control gas circuit, it comprises: one carries out gas circuit 10 (representing with straight line in figure) and controls gas circuit 20 (being represented by dotted lines in figure), described execution gas circuit 10 one end are connected with a source of the gas (not shown), and the other end is connected with a pneumatic ball valve 40 by a two-position five-way Pneumatic valve 30; In described control gas circuit 20, include and connect successively reduction valve 22, throttle valve 24 and the air-capacitor 26 arranging, these reduction valve 22 one end are connected in source of the gas and carry out position between gas circuit 10, air-capacitor 26 one end are connected with two-position five-way Pneumatic valve 30, this air-capacitor 26 is also connected with a machine control valve 50, and these machine control valve 50 one end are connected with atmosphere.The gas control time of the present utility model is controlled gas circuit at work, when manually booting machine control valve 50, air enters air-capacitor 26, pressurized air in air-capacitor 26 is emptying, thereby make the valve core spring return of two-position five-way Pneumatic valve 30, and then two passages connections of two-position five-way Pneumatic valve 30, realize the control to pneumatic ball valve 40; When machine control valve 50 cuts out, source of the gas by reduction valve 22 and throttle valve 24 to the interior inflation of air-capacitor 26, when air-capacitor 26 internal air pressures reach the pressure that overcomes two-position five-way Pneumatic valve 30 spool return springs, the 30 spool commutations of two-position five-way Pneumatic valve, its two other passage is connected, thereby realize, the commutation of pneumatic ball valve 40 is controlled.
In the utility model, described two-position five-way Pneumatic valve 30 preferably adopts two-position five-way list Pneumatic valve, carries out gas circuit 10 and is connected with pneumatic ball valve 40 by this two-position five-way list Pneumatic valve.As a kind of selectivity embodiment of the present utility model, this two-position five-way Pneumatic valve 30 can adopt the two-position five-way list Pneumatic valve that the model of SMC company is SYA5120-02.Described two-position five-way list Pneumatic valve includes 1,2,3,4,5 these five passage ventilations as shown in Figure 1, when manually booting machine control valve 50, pressurized air in emptying air-capacitor 26, two-position five-way list Pneumatic valve valve core spring return, thus 1,2 passages of this two-position five-way list Pneumatic valve are connected; And when machine control valve 50 cuts out, when reaching the spool return spring pressure of two-position five-way list Pneumatic valve, the commutation of two-position five-way list Pneumatic valve spool, 1,4 passages are connected, thereby realize, the commutation of pneumatic ball valve 40 are controlled.
Further, also include an air filter 21 in described control gas circuit 20, reduction valve 22 one end are connected in source of the gas and are carried out position between gas circuit 10 by this air filter 21.This air filter 21 filters for the gas that source of the gas is provided, and reduction valve 22 is by regulating, and can control the required level of gas circuit 20 by controlling before valve after gas pressure that gas circuit 20 is higher is reduced to valve.As a kind of alternative embodiment of the present utility model, described air filter 21 can adopt the air-source treater that the model of SMC company is AF20-01BC.It is the reduction valve of AR20-02H or AR20P-580AS that described reduction valve 22 can adopt the model of SMC company equally.
Further, in the control gas circuit 20 between described reduction valve 22 and throttle valve 24, be also provided with a pressure gauge 23.Because two-position five-way Pneumatic valve 30 is Pneumatic valves of a kind of spring reset, realize the commutation of this two-position five-way Pneumatic valve 30, control gas circuit 20 and just must reach certain pressure, therefore, one pressure gauge 23 is set between reduction valve 22 and throttle valve 24, by adjusting, control supply pressure and the flow of gas circuit 20, controlled thereby realization control gas circuit 20 reaches the time that forces two-position five-way Pneumatic valve 30 to commutate.Described reduction valve 22 can interact with throttle valve 24, also constant pressure or flow can be set respectively, realizes the aeration speed of controlling gas circuit 20 by adjust flux or pressure.In the utility model, described pressure gauge 23 can be selected the pressure gauge that the model of SMC company is G46-10-01LN-C.Described throttle valve 24 can be selected the throttle valve that the model of SMC company is AS1000-M3, for carrying out air inlet restriction.Described air-capacitor 26 is for zooming in or out control time section district, and not isometric air-capacitor can realize the setting in multiple different time sections district.
In sum, the gas control time of the present utility model is controlled gas circuit, it is by the circuit design of advantages of simple, can substitute the automatically controlled application in explosion-proof high prestige environmental area of tradition, eliminate traditional because making electricity consumption may cause installing at explosion-proof area the potential safety hazard of this kind equipment completely, not only can be significantly cost-saving, and facilitate large-scale industry to promote the use of.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
