Abstract

Вентиль, как правило, используемый в нефтяной или газовой скважине и содержащий подвижный элемент, такой как шар, выполненный с возможностью перемещения между открытым и закрытым положениями, содержащий режущий узел, предназначенный для выполнения резания совместно с опорным элементом, когда шар перемещается между открытым и закрытым положениями; и содержащий уплотнительный элемент, имеющий седло для прижимания к подвижному элементу, когда этот подвижный элемент находится в закрытом положении. Опорный элемент и уплотнительный элемент выполнены с возможностью перемещения один относительно другого, когда подвижный элемент перемещается из открытого положения в закрытое положение, так что во время открывания и закрывания вентиля уплотнительный элемент перемещается от режущего узла (как правило, внутренней поверхности отверстия), когда режущий узел взаимодействует с опорным элементом. Уплотнительный элемент отталкивается от подвижного элемента и опорного элемента на максимальное расстояние от подвижного элемента в той точке хода подвижного элемента, в которой режущая поверхность подвижного элемента проходит опорный элемент, так что уплотнительный элемент перемещается из зоны соприкосновения с шаром, когда режущая поверхность взаимодействует с опорным элементом, и опять вводится в соприкосновение с шаром, когда режущая поверхность выходит за пределы опорного элемента и уплотняемая поверхность шара выравнивается с уплотнительным элементом.
