Do you know the use of tungsten carbide flow control valves?


Tungsten carbide flow control valves can play a role in controlling the flow of fluid, generally speaking, when the pressure difference of the flow control valve is fixed, the size of the opening affects the change of liquid flow. In simple terms, the main role of the throttle valve is three points:

1. The role of interception and speed regulation

The flow control valve changes the flow rate by controlling the throttle section or length, which is the main role of the flow control valve and its main function.

2. Play the role of load resistance

The flow control valve can also play a certain degree of load, which is only part of the function of the flow control valve, and the main role of the flow control valve is still to regulate the speed of the throttle.

3. The role of pressure buffering

The flow control valve can act as a pressure buffer for the fluid, when the fluid flows through the throttle valve, the throttle valve can hinder the operation of the fluid to a certain extent and reduce the impact force.


Classification of flow control valves

The flow control valve can be divided into straight-through type and angle type according to the channel mode; According to the shape of the opening and closing parts, there are three kinds of needle shape, groove shape and window shape.

Adjustable valve: The valve pin and spool are made of cemented carbide, and the products are designed according to API6A standards, with wear and wash resistance. Mainly used for wellhead oil (gas) tree equipment,

Slip sleeve flow control valve: the valve core adopts low noise balance structure, open lightly,the spool surface is covered with tungsten carbide, suitable for flash, high pressure difference, high pressure, cavitation and other harsh occasions, long service life, flow adjustment accuracy greatly improved. Suitable for oil, natural gas, chemical, refining, hydropower and other industries.
