Model utility content
Based on the problems referred to above, the utility model object is the extend neck parts providing compressor, can stop to reveal gas and enter fuselage by the first chamber through the second chamber, and can realize faster revealing gas purging.
For above problem, provide following technological scheme: the extend neck parts of compressor, comprise the cylindrical shell of tubular construction, cylindrical shell is provided with the first chamber and the second chamber that intermediate clapboard is isolated into two opposing seal, the top of the first chamber and the second chamber is provided with drain, bottom is provided with blowdown valve, intermediate clapboard is provided with intermediate seal filler, piston rod is reserved with nitrogen protection chamber through during intermediate seal filler in the middle part of it, second chamber is provided with the nitrogen gas tube leading to nitrogen protection chamber on intermediate seal filler, it is characterized in that: described nitrogen gas tube is also communicated in the first chamber and arranges, intermediate seal filler is respectively arranged with the breather line being communicated in nitrogen gas tube, this breather line is communicated in the first chamber respectively and nitrogen protection chamber is arranged, first chamber is provided with and is communicated in outside exhaust gas recycling tube.
The utility model is set to further, and the second described chamber is also provided with oil-scraping device, and the inner side of oil-scraping device is provided with stuffing box packing.
The utility model is set to further, the first described chamber is provided with filler and is connected to the oil filler pipe of this filler and rushes nitrogen pipe.
The beneficial effects of the utility model: due to the nonabsoluteness of sealing, reveal in gas the first chamber of being present in extend neck and the second chamber, and the density of leakage gas in the first chamber is greater than the second chamber, when leakage gas enters the first chamber by cylinder, nitrogen gas tube can stop leakage gas to enter the second chamber on the one hand as far as possible, the discharge of the gas of the first chamber can be accelerated on the other hand, reduce the leakage gas density of the first chamber, reveal gas at the second chamber amount to reduce further.
