Abstract
(EN)
A method for designing end face structures of a stator and a rotor of an oscillating shear valve in a non-uniform velocity motion state and the oscillating shear valve, which relate to the technical field of measurement during drilling for petroleum and natural gas engineering. The oscillating shear valve comprises a rotor (2) and a stator (3); the rotor (2) comprises a plurality of blades (22), and a notch (21) between every two adjacent blades (22) is composed of a circular arc line and two linear segments; the two linear segments are both parallel to a polar radius which penetrates the circle center of the circular arc line; and the number of blades (31) comprised by the stator (3) is the same as that of the rotor (2); the end face structures of the blades (31) of the stator (3) are consistent with the stator (2). When the rotor (2) has accelerating velocity, uniform velocity or decelerating velocity motion characteristics and swings back and forth relative to the stator (3), a continuous wave mud pulse generator may output sinusoidal pressure wave signals of similar heights, and important application value is thus achieved.

L'invention concerne un procédé de conception de structures de face d'extrémité d'un stator et d'un rotor d'une vanne de cisaillement oscillant dans un état de mouvement de vitesse non uniforme et la vanne de cisaillement oscillant, qui se rapportent au domaine technique de la mesure pendant le forage pour l'ingénierie du pétrole et du gaz naturel. La vanne de cisaillement oscillant comprend un rotor (2) et un stator (3) ; le rotor (2) comprend une pluralité de pales (22) et une encoche (21) entre chaque paire de lames adjacentes (22) est composée d'une ligne d'arc circulaire et de deux segments linéaires ; les deux segments linéaires sont tous deux parallèles à un rayon polaire qui pénètre dans le centre de cercle de la ligne d'arc circulaire ; et le nombre de pales (31) compris dans le stator (3) est identique à celui du rotor (2) ; les structures de face d'extrémité des pales (31) du stator (3) sont cohérentes avec le stator (2). Lorsque le rotor (2) a des caractéristiques de mouvement de vitesse d'accélération, de vitesse uniforme ou de vitesse de décélération et oscille en va-et-vient par rapport au stator (3), un générateur d'impulsions de boue à onde continue peut délivrer des signaux d'onde de pression sinusoïdale de hauteurs similaires et une valeur d'application importante est ainsi obtenue.
