Abstract

Inventia se refera la o supapa pentru gazlift folosita pentru pornirea sondelor de petrol. Supapa pentru gaz lift este caracterizata prin a aceea ca în interiorul niplului este montat un manson din cauciuc introdus în interiorul unui silfon cilindric, confectionat din tabla, sudat longitudinal. Mansonul si silfonul sunt prinse etans de tija amintita cu ajutorul unei piulite si de o prelungire tubulara cu ajutorul altei piulite. Mansonul delimiteaza o camera încarcata cu un fluid sub presiune introdus prin supapa de încarcare al carui capat patrunde într-un guler inferior al piulitei fixate în capatul corpului tubular, ceea ce permite demontarea ei, iar un surub prevazut cu o garnitura închide corpul tubular.The invention relates to a gaslift valve used for starting the oil wells. The gas lift valve is characterized in that a rubber sleeve is inserted into the nipple inside a cylindrical silve made of sheet metal, longitudinally welded. The manhole and the silfon are tightly attached to the stem by means of a nut and a tubular extension by means of another nut. The sleeve delimits a chamber loaded with a pressurized fluid introduced through the charging valve, the end of which enters the lower nut of the nut fixed to the end of the tubular body, which allows its removal, and a screw provided with a gasket closes the tubular body.
