What is the purpose of the choke valve?
A choke valve is a mechanical device that induces restriction in a flow line, causing either a pressure drop or a reduction in the rate of flow. See Figure 1. In the context of the upstream oil and gas industry, choke valves are used wherever there is a requirement for wellhead flow and pressure control.
Where is the choke valve located?
Choke is a butterfly valve that mounted on the inlet of air passage of carburetor (upstream from carburetor venturi tube). Normally choke will be in open position, in which valve is parallel to the air flow, and has no effect on the air flow.
What is the difference between valve and choke?
Check valves are unidirectional valves. Choke is a type of valve which is used to control flow of fluid and reduce pressure. Chock is used in engines to control the amount of fuel provision to engines. Valve is used for inlet and exhaust of the fuel and combustible products.
What is choke manifold valve?
A choke manifold is an arrangement of piping and valves with adjustable choke valves. These valves are designed specifically to restrict flow when needed (hence the term choke). By adjusting these valves as needed, flows can be regulated as required.
What is the purpose of choke valve in oil and gas?
Choke valve, sometimes also known as ‘choker valve’ is a type of control valve, mostly used in oil and gas production wells to control the flow of well fluids being produced. Another purpose that the choke valves serve is to kill the pressure from reservoir and to regulate the downstream pressure in the flowlines.
What happens when choke is pulled?
By pulling the choke you increase the amount of fuel to the engine.. So.. while starting the vehicle on a cold day, the engine needs more amount of fuel to heat up the engine for normal performance of the vehicle… It is not recommended to put the choke on and drive the bike..
Is choke valve a control valve?
What is choke manifold in oil and gas?
A choke manifold is an assembly of piping and valves with adjustable choke valves. This arrangement is mainly responsible for controlling flows and pressures during the onshore and offshore well testing and production operations.
What is the purpose of a choke valve?
Choke valves are used to control flow rate and reduce pressure for processing of produced fluids farther downstream. Effective chokes reduce the likelihood of damage to downstream equipment, support longer lasting production timespans, and alleviate stress from field operators by keeping them away from the wellhead.
What are the applications of production choke?
production choke applications, including ■ wellhead—attaches to the wing valve on the production tree and provides great control for oil and gas production ■ manifold—maintains pressures and control flow rates in oil or gas production systems and enables pressure control in choke and kill manifolds
What is a drilling choke?
the drilling choke trim rotates through a control range from fully open to fully closed in 180°� This design delivers control so reliable that the drilling choke outperforms other designs for well killing and pressure control, especially in severe service involving H2S, abrasive fluids, and high pressures�
What is the best choke style for natural gas?
Standard service valves are the most cost- efficient choke styles� They generally are intended for sweet crude oil, deaerated water, sweet natural gas, and other noncorrosive fluids� 2. Style 8—Sour service In addition to the requirements of the standard valve type, the materials of the
