Abstract

The invention belongs to a fixing valve, comprising a strip-shaped nut, a fixing valve shield and a U-shaped combined joint; a first round hole is formed in the top of the fixing valve shield; a second round hole is formed in the bottom of the fixing valve shield; the strip-shaped nut is arranged in the second round hole; the U-shaped joint is arranged in the first round hole; a scale settling device is arranged below the strip-shaped nut. The mode of jointing the U-shaped combined joint and the scale settling device is adopted by the fixing valve, the sundry, sand and scales are blocked in the annular space formed by the U-shaped combined joint and the fixing valve shield, sands and scales are prevented from being accumulated in the inner cavity of the scale settling device, and the fixing valve is prevented from being blocked, so the use period is prolonged and the production efficiency o f an oil field is improved.

Description

technical field [0001] The invention relates to a fixed valve. Background technique [0002] The fixed valve in the traditional oil production process is affected by factors such as the debris on the inner wall of the pumping string falling into the well and the formation of sand and scaling. Deposition seriously affects the normal opening and closing of the fixed valve, thus causing the fixed valve to be stuck. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixed valve that prevents sand and scale from depositing on the fixed valve cover. [0004] In order to solve the above problems, the present invention adopts the following technical solution: a fixed valve, including a bar nut, a fixed valve cover and a U-shaped combined joint, the top of the fixed valve cover is provided with a first round hole, and the bottom of the fixed valve cover A second round hole is provided, the bar nut is arranged in the seco...
