Abstract
The utility model relates to a kind of metering valve plate power-off protection apparatus; the device includes the first solenoid valve being connected and second solenoid valve; the air inlet P of first solenoid valve is connected with compressed air; the gas outlet A of first solenoid valve is connected with the exhaust outlet S of the second solenoid valve, and the gas outlet B of the second solenoid valve is connected with cylinder.Using the metering valve plate power-off protection apparatus of the utility model, the waste such as material caused by capable of saving because of power-off, artificial；Power-off protection can be carried out to the valve plate type dosing machine with large and small function of measuring.
Description
Technical field
The utility model relates to field of measuring techniques more particularly to valve plate dosing machine, in particular to a kind of metering valve plate are disconnected
Electrical protective device.
Background technique
The valve plate of valve plate type dosing machine, if powered off in certain component metering process, metering valve plate can be because lose
Control stops in situ, it is possible to lead to the large quantities of wastes of material in metering.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of can save because power-off causes
Material, the waste such as artificial；The metering valve plate that power-off protection can be carried out to the valve plate type dosing machine with large and small function of measuring is disconnected
Electrical protective device.
To achieve the goals above, the utility model provides a kind of metering valve plate power-off protection apparatus, main feature
It is that the device includes the first solenoid valve being connected and second solenoid valve, the air inlet P and pressure of first solenoid valve
Contracting air is connected, and the gas outlet A of first solenoid valve is connected with the exhaust outlet S of the second solenoid valve, described
The gas outlet B of second solenoid valve be connected with cylinder.
Preferably, first solenoid valve is 2/2-way normal-closed electromagnetic valve or two-bit triplet solenoid valve.
Preferably, the second solenoid valve is three center-leakage type solenoid valves.
Preferably, the first solenoid valve power loss is normally closed so that compressed air passes through when the described dosing machine accident power-off
The air inlet P of the solenoid valve enters gas outlet A, enters back into and the row of the gas outlet A second solenoid valve being connected
Port S drives cylinder to measure valve plate closing by the gas outlet B of the second solenoid valve.
Using the metering valve plate power-off protection apparatus of the utility model, material caused by capable of saving because of power-off, artificial etc.
Waste；Power-off protection can be carried out to the valve plate type dosing machine with large and small function of measuring.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the metering valve plate power-off protection apparatus of the utility model.
Appended drawing reference
1 first solenoid valve
2 second solenoid valves
Specific embodiment
In order to more clearly describe the technology contents of the utility model, carry out combined with specific embodiments below into one
The description of step.
As shown in Figure 1, the utility model provides a kind of metering valve plate power-off protection apparatus, it is mainly characterized by, it is described
Device include the first solenoid valve 1 being connected and second solenoid valve 2, the air inlet P of first solenoid valve and compression are empty
Gas phase connection, the gas outlet A of first solenoid valve is connected with the exhaust outlet S of the second solenoid valve, and described the
The gas outlet B of two solenoid valves is connected with cylinder.
In a kind of preferably embodiment, first solenoid valve is 2/2-way normal-closed electromagnetic valve or two three
Three-way electromagnetic valve, the utility model is without being limited thereto, and the solenoid valve of other forms also can be used.
In a kind of preferably embodiment, the second solenoid valve is 3 position-5 way solenoid valve or two five energization magnetic
Valve, the utility model is without being limited thereto, and the solenoid valve of other forms also can be used.Preferably, the second solenoid valve is three
Position center-leakage type solenoid valve.
In a kind of preferably embodiment, dosing machine be switched on it is electric after, the first solenoid valve excitation is normally opened；The metering
When machine accident power-off, the first solenoid valve power loss is normally closed to enter compressed air through the air inlet P of the solenoid valve
Gas outlet A, enter back into the exhaust outlet S of the gas outlet A second solenoid valve being connected, pass through the second solenoid valve
Gas outlet B driving cylinder make measure valve plate close.
Using the metering valve plate power-off protection apparatus of the utility model, material caused by capable of saving because of power-off, artificial etc.
Waste；Power-off protection can be carried out to the valve plate type dosing machine with large and small function of measuring.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still can be with
The spirit and scope that various modification can be adapted and converts without departing from the utility model.Therefore, the description and the appended drawings should be considered as
It is illustrative and not restrictive.
