Electric sleeve type adjustable throttling valve

Abstract

The invention relates to the technical field of flow valves, and discloses an electric sleeve type adjustable throttling valve. The electric sleeve type adjustable throttling valve comprises a valve body, an O-shaped ring is fixedly connected to the inner wall of the valve body, a valve seat body is movably connected to the inner wall of the O-shaped ring, a rolling wheel on the upper surface of the valve seat body is provided with a sleeve body, an inner lining body is fixedly connected to the surface of the sleeve body, a valve clack body is fixedly connected to the surface of the inner lining body, a valve rod is movably connected to the top of the valve clack body, and a lower anti-rotation gasket and an upper anti-rotation gasket are movably connected to the surface of the valve rod.The electric sleeve type adjustable throttling valve has the advantages that when the electric sleeve type adjustable throttling valve is opened, all the inner cavity surfaces which fluid passes through are provided with Inconel 625 nickel-based alloys in a surfacing mode, the hardness is high, the wear resistance is good, the corrosion resistance is excellent, scouring by the fluid at high pressure for a long time can be resisted, the valve can be prevented form being eroded and damaged, and therefore the service life of the valve can be prolonged, and accidents caused by the damage to the valve can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of flow valves, in particular to an electric sleeve-type adjustable flow valve. Background technique [0002] The western region of my country is rich in oil reserves, but the working conditions in the western region are complex, and some oil wells are drilled and produced with the characteristics of large oil (gas), high pressure, high hydrogen sulfide content in the fluid, and strong scour force. Conventionally designed valves are often unable to withstand the strong erosive force of the fluid, the inner cavity of the valve body and the sealing surface of the valve internal parts are quickly damaged, and cannot work normally. In severe cases, puncture leakage or even valve disintegration occurs. At the same time, the conventionally designed valve uses a handwheel to control the opening and closing of the valve, which takes a long time and has low transmission efficiency. In an emergency, it is prone to saf...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an electric sleeve-type adjustable throttle valve, which solves the problem that conventionally designed valves use a handwheel to control the opening and closing of the valve, which takes a long time and has low transmission efficiency, which is easy to occur in emergency situations. Unable to open and close and other safety hazards
