THE WORKING PRINCIPLE AND FUNCTION OF CHOKE VALVE

The Choke Valve Function

The choke valve can play a role in controlling the fluid flow. Generally speaking, when the pressure difference of the choke valve maintains a certain amount, the opening size of the choke valve will affect the change of liquid flow. In short, the choke valve plays three main roles:

Function 1: interception and speed regulation

The choke valve changes the flow rate by controlling the cross-section of the length of the choke. This is the main effect and the main function of the choke valve.

Function 2: play the role of loading resistance

The choke valve can also play a role in loading resistance to a certain extent. This is only a part of the function of the choke valve. The main function of the choke valve is still speeding regulation.

Function 3: play the role of pressure-buffering

The choke valve can buffer the pressure of the fluid. When the fluid flows in through the choke valve, the choke valve can hinder the flow of the fluid to a certain extent to reduce the impact force.

Choke Valve Working Principle

The choke valve is very similar to the cut-off valve in appearance and structure. The only difference between them is the shape of the disc and the working stroke. Therefore, the parts of the choke valve and the cut-off valve are highly interchangeable.

All kinds of shut-off valves can change the cross-sectional area of the medium channel, and thus can also play an adjustment role to a certain extent, but their adjustment performance is not that good. This is because their open-close parts and the valve stem are movably connected, and there is a gap at the joint, which leads to the inconvenience in adjustment; the lifting of the open-close parts is not proportional to the change of the channel area, so it is not easy to make accurate and continuous adjustments. When the channel area is small and the medium flow rate is high, it will cause severe erosion of the sealing surface and cause the vibration of the disc. Therefore, a choke valve with a special structure and an open-close shape is usually used for adjustment and to ensure smooth choke valve operation.

The choke valve is a valve that controls the flow of fluid by changing the cross-section of the length of the choke. Let us take a look at the working principle and function of the choke valve. >> sucker rod pump  tungsten carbide 18k gold ring allulose manufacturers
