Wedge choke valve

Wedge type manual choke valve, one side of the valve core is close to the inner wall of the valve seat, so that the valve core will not vibrate after being impacted by the fluid. By setting a diversion surface, the lateral force of the fluid on the valve core is reduced, the possibility of valve core fracture is greatly reduced, the occurrence of oil well blowout is avoided, and the safety of oil well operation is improved; A concave arc surface is arranged between the inclined guide surface and the axial guide surface to improve the anti erosion ability of the valve core and the service life of the valve core.
