Abstract
The invention relates to an oil and gas recovery oil filling gun with a non-pressure self-sealing function and an oil filling method thereof. The oil and gas recovery oil filling gun comprises a connecting thread, a gas path connector, a gun body, an oil and gas separator, a handle sleeve, a valve, a trigger, a roller pin, a diaphragm, a gas adjusting device, a non-pressure self-sealing device, a one-way valve and an oil outlet pipe. According to the technical scheme, the oil and gas recovery oil filling gun can be applied to the secondary oil and gas recovery stage, has the non-pressure self-sealing function and is suitable for a self-help oil filling machine; the oil filling gun can seal an oil path automatically after the oil filling machine is completely stopped, and therefore the situation that because the oil filling gun is not self-sealed after the last time of oil filling, fuel oil leaks in the process of secondary oil filling and danger is caused will not occur; the one-way valve arranged in the oil filling gun can be synchronously opened in the process of oil filling and can be completely closed after the oil filling gun is self-sealed, and therefore oil dripping occurring after the oil filling gun is self-sealed can be effectively prevented.
