| description | The utility model discloses a low-shear regulating valve, which is used for injecting polymer viscous mother liquor in an oil field and comprises an electric actuator and a valve body, the valve body comprises a valve cover, a valve seat and a valve rod with a valve core, an inner cavity of the valve seat is provided with a tapered hole, and the tapered valve core is oppositely arranged at the end part of the valve rod. The valve element is driven by the electric actuator to be movably arranged in the axial direction of the valve seat. According to the low-shear regulating valve, through the design of the flow channel valve cavity with the taper, when the low-shear regulating valve is used for mother liquor conveying operation of oil field engineering, flowing of viscous media and entrainment polymeric fiber media can be met, compared with the prior art, shear is not generated in the regulating process, influences on the media are avoided, and in addition, the low-shear regulating valve is suitable for being |
