Abstract
1. Промывочный клапан, содержащий соединенный с насосно-компрессорными трубами (НКТ) цилиндрический корпус с радиальными отверстиями, подвижную подпружиненную герметизирующую втулку, размещенную в корпусе с образованием поршневой пары, отличающийся тем, что он снабжен установленными с обеих сторон корпуса переводниками, первый из которых предназначен для соединения с НКТ, а второй - для соединения с подъемным патрубком не вставного штангового насоса, а также штоком с муфтой для соединения со штангами и возможностью свободного перемещения внутри клапана, при этом внутренняя поверхность втулки имеет участок конической формы, обеспечивающий опору муфты штока при освобождении штока от канатной подвески станка-качалки для перемещения герметизирующей втулки клапана до совмещения с отверстиями в корпусе клапана и открытия сообщения полости НКТ с затрубным пространством.2. Промывочный клапан по п.1, отличающийся тем, что на обращенных друг к другу поверхностях втулки и второго переводника выполнены опорные седла для размещения между ними пружины.1. A flushing valve comprising a cylindrical body with radial holes connected to tubing (tubing), a movable spring-loaded sealing sleeve, placed in the body with the formation of a piston pair, characterized in that it is equipped with sub-mounted on both sides of the body, the first of which it is designed to connect to the tubing, and the second - to connect to the lifting pipe of a non-plug-in sucker-rod pump, as well as a rod with a coupling for connecting to the rods and the possibility of free movement inside the valve, while the inner surface of the sleeve has a conical section that provides support for the stem coupling when the rod is released from the rope suspension of the rocking machine to move the valve sealing sleeve to align with the holes in the valve body and open the tubing cavity with the annulus. 2. The flushing valve according to claim 1, characterized in that on the facing surfaces of the sleeve and the second sub, support seats are made to accommodate springs between them.
