Internal Sleeve Choke Valve

It can be used to control fluid flow in various service conditions, including single-phase and poly-phase(oil, gas and water). With 64-case visual position indicator, the fluid flow is well controlled.This kind of choke valve can be operated manually, pneumatic or electric drives and many other kinds of forms, to facilitate customer choice.

Orifice type throttle valve includes a throttle body, an upper valve plate and a lower valve plate which are disposed inside the throttle body body and sealed together, a valve stem fixedly connected to the upper valve plate at the lower end, a transmission shaft and a transmission a hand wheel fixedly connected to the upper end of the shaft, the transmission shaft is a hollow structure, the valve rod is vertically movable and sealed inside the transmission shaft, the valve rod and the transmission shaft are provided with a flat key, and the top of the transmission shaft is screwed a pressing rod, the lower end surface of the pressing rod is in contact with the upper end surface of the valve stem. The invention sets the transmission shaft as a hollow structure, and further adds a pressing rod, and the gap between the upper valve plate and the lower valve plate is controlled by the pressing rod to ensure good sealing between the upper valve plate and the lower valve plate.
