Abstract

The invention provides an oil well pump and a valve structure, and relates to the technical field of oil exploitation. The valve structure comprises a valve cover, a valve seat, a plugging piece, a guide column and a sealing piece. The valve cover is provided with a first end and a second end which are communicated, the first end is internally provided with a boss, the second end is internally provided with a fixing part, and the fixing part is provided with a guide hole and an oil through hole which are communicated in the axial direction of the valve cover; the valve seat is provided with athrough bottom end part and a through top end part, and the top end part abuts against one side, away from the second end, of the boss; the plugging piece is arranged in the valve cover and comprisesa bottom surface and a side surface surrounding the bottom surface, the side surface is movably abutted with the top end part of the valve seat, the bottom surface faces the second end, the radial size of the plugging piece is equal to the inner diameter of the boss, and the plugging piece is flush with one side, close to the second end, of the boss; one end of the guide column is connected with the bottom surface, and the other end of the guide column slidably penetrates through the guide hole; and the sealing piece is arranged outside the guide column in a sleeving mode, covers the bottom surface and one side, close to the second end, of the boss, and is made of an elastic material.

Description

technical field [0001] The present disclosure relates to the technical field of oil exploitation, in particular, to an oil well pump and a valve structure. Background technique [0002] In the field of oil extraction, the oil pump is an essential equipment, which can lift the crude oil in the well to the ground. Valves are generally used in existing oil well pumps to realize the one-way flow of oil, and Valves are valves. Existing valves are usually opened and closed by contacting or separating valve balls and valve seats. However, in actual use, foreign particles such as sand and stone often appear between the ball and the seat, resulting in a gap between the ball and the seat, so that the pumped oil may flow back, that is, leak, and affect the oil recovery efficiency . [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include in...
