After adopting technique scheme, the utility model compared with prior art has following beneficial effect: this device does not use pressure transducer, avoid because pressure transducer damages and cause and cannot report to the police, more ensure that reliable warning in conjunction with two warning branch roads, ensure that the safety of surrounding enviroment and personnel.
Accompanying drawing explanation
Schematic diagram when Fig. 1 is gas holder non-superpressure.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, a kind of pressure gas tank superpressure self-alarming device, a pressure-measuring pipe 2 is connected with at gas holder 1, the mouth of pipe of described pressure-measuring pipe 2 is connected with the first pressure measurement air bag 3, also comprise a sealing liquid container 4, described sealing liquid container 4 is separated into the first liquid storage cylinder 41 and the second liquid storage cylinder 42 by a vertical demarcation strip 5, linked hole 6 is had bottom described demarcation strip 5, described first pressure measurement air bag 3 is arranged in described first liquid storage cylinder 41, second liquid storage cylinder 42 is connected with liquid level sensor, and described liquid level sensor connects the warning circuit of warning device; Described pressure-measuring pipe 2 is also connected with the second pressure measurement air bag 7, a mounting plate is provided with in described second pressure measurement air bag 7 side, towards the side of described second pressure measurement air bag 7, touch switch 9 is housed at described mounting plate, described touch switch 9 is connected in the warning circuit of described warning device.
The principle of this device is: in the first liquid storage cylinder 41 and the second liquid storage cylinder 42, liquid is all discontented, designing air bag before gas holder 1 reaches maximum capacity does not in advance enter in the liquid of the first liquid storage cylinder 41, when gas holder 1 superpressure, enter in the liquid of the first liquid storage cylinder 41 bottom air bag, along with the increase of air bag volume, first liquid storage cylinder 41 and the second liquid storage cylinder 42 liquid level all raise, and detect that the second liquid storage cylinder 42 liquid level raises rear warning circuit and reports to the police at liquid level sensor.In order to guarantee the reliable of warning further, this device also has the second pressure measurement air bag 7, its maximum capacity is also a bit larger tham gas holder 1, set when gas holder 1 does not reach maximum capacity in advance, second pressure measurement air bag 7 does not reach touch switch 9, when gas holder 1 superpressure, the second pressure measurement air bag 7 contacts touch switch 9, and trigger alarm circuit realiration is reported to the police.This device does not use pressure transducer, avoids because pressure transducer damages and causes and cannot report to the police, more ensure that reliable warning, ensure that the safety of surrounding enviroment and personnel in conjunction with two warning branch roads.Schematic diagram when Fig. 1 is gas holder 1 non-superpressure.
Warning circuit can adopt existing custom circuit, and as touch switch is connected in a warning power circuit, this power circuit comprises an alarm terminal, power supply and described touch switch, and after contact touch switch, power circuit is connected and realized reporting to the police by touch switch.Warning circuit also comprises a controller, one drive circuit and an alarm terminal, the input of the output connection control device of liquid level sensor, the output of controller connects alarm terminal by drive circuit, when liquid level sensor detects that liquid level rises to controller output signal, controller controls alarm terminal and reports to the police.
In order to be easier to make the liquid in the first liquid storage cylinder 41 enter in the second liquid storage cylinder 42, preferably offering at least three apertures at described second liquid storage cylinder 42 top, thus the superpressure of gas holder 1 can be detected fast.
Because present cable unit price is higher, therefore in order to save cable cost, preferably, described mounting plate is the casing 8 of described warning device, described touch switch 9 is in the outside of described warning device casing 8, leaded hole on the casing 8 of described warning device, the connecting line of described touch switch 9 puts in the casing 8 of described warning device from described fairlead and is connected with described warning circuit.Save touch switch 9 and the length of cable (if touch switch 9 and warning device are not together, then also needing the cable using certain length between both) of warning device, provide cost savings.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
