Disclosure of Invention
The utility model aims at providing a convenient to use, and detect the higher non-repeated dress container detection device that fills of precision.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a non-repeated dress container detection device that fills, includes air supply and first gas-supply pipe, the inlet end and the air supply intercommunication of first gas-supply pipe, the end of giving vent to anger of first gas-supply pipe is used for filling the valve with the non-repetition of waiting to detect the container and is connected, be equipped with first control valve, first manometer on the first gas-supply pipe, and the inlet end and the first gas-supply pipe intercommunication of disappointing the pipe, first manometer is located between the inlet end of first control valve and disappointing pipe, the inlet end of disappointing the pipe is more close to the end of giving vent to anger of first gas-supply pipe than first manometer, be equipped with the second control valve on the disappointing pipe.
When the device is used, the valve rod of the non-repeated filling valve of the non-repeated filling container is firstly screwed to the bottom to realize the damage of the valve rod, then the valve nozzle of the non-repeated filling valve is connected with the air outlet end of the first air delivery pipe, then the first control valve is opened and the non-repeated filling valve is opened, so that the second control valve is closed, and the opening of an air source is kept for a period of time; subsequently closing the first control valve and the non-refillable valve and opening the second control valve to bring the value on the first pressure gauge to 0; and finally, closing the second control valve and opening the non-repeated filling valve, if the first pressure gauge shows that the pressure is increased, judging that the non-repeated filling valve of the non-repeated filling container for sampling inspection is unqualified, and otherwise, judging that the non-repeated filling valve is qualified. The utility model can detect the non-repeated filling containers, does not need to carry and weigh the non-repeated filling containers, does not need to record the front and back weighing of the non-repeated filling containers, and is very convenient to use; as long as compressed air is filled in the non-repeated filling container, the numerical value on the first control valve can be changed, so that the utility model discloses it is higher to detect the precision.
Preferably, the air inlet end of the first air conveying pipe is connected with the pressure stabilizing tank, a second air conveying pipe is connected between the pressure stabilizing tank and the air source, the air inlet end of the second air conveying pipe is connected with the air source, the air outlet end of the second air conveying pipe is connected with the pressure stabilizing tank, a third control valve and a second pressure gauge are arranged on the second air conveying pipe, and the second pressure gauge is closer to the air outlet end of the second air conveying pipe than the third control valve.
By providing a surge tank, the pressure of the compressed air moving to the non-refillable side of the container is made more stable to ensure that non-refillable containers that are not valve-fail (the valve stem will not break after being screwed to the bottom to close the non-refillable container) can be filled with compressed air.
Preferably, the second gas transmission pipe is provided with a pressure reducing valve, and the third control valve is positioned between the pressure reducing valve and the second pressure gauge. By arranging the pressure reducing valve, the pressure of the detected compressed air is smaller, and the detection safety is improved.
The utility model has the advantages of convenient to use, and detect the precision higher.
