What is a orifice valve?

1. n. [Well Completions] A type of valve, typically found on small-diameter pipework, that incorporates an orifice or flow-restriction device to control fluid flow.

What is in an orifice?

English Language Learners Definition of orifice : a hole or opening and especially one in your body (such as your mouth, ear, nostril, etc.)

What is the purpose of the orifice?

An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).

What is heart orifice?

The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle. Situated at the base of the atrium, it measures about 3.8 to 4 cm.

What are the types of orifice?

Types of orifice plates

• Concentric orifice plate.
• Eccentric orifice plate.
• Segmental orifice plate.
• Quadrant edge orifice plate.

Is a valve an orifice?

An orifice valve is a flow control valve that is used to restrict or control the fluid flow. An orifice is a small opening or hole in a plate or pipe or body. When the fluid passes through the orifice, the fluid flow gets restricted.

What are some examples of orifice?

The definition of an orifice is an opening, especially an opening to the body or the opening of a tube or pipe. The mouth is an example of an orifice. An opening, especially to a cavity or passage of the body; a mouth or vent. A mouth or aperture of a tube, cavity, etc.; opening.

What is orifice and its types?

Orifice plates are one of the most popular devices for the measurement and control of fluid flow. It is frequently used more than any other flow meter. The orifice consists of a thin metal plate with a straight hole drilled in it.

How do I know my orifice size?

Divide the flow of the liquid by the velocity of the liquid to determine the area of the orifice in square feet. In the above example, you would divide 8 by 2. The total area of the orifice would be 4 square feet.

On which side of the heart is low in oxygen?

right side
The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen.

What is double orifice?

Double orifice mitral valve (DOMV) is a rare congenital anomaly of the subvalvar mitral valve apparatus (chordae tendinae and papillary muscles) consisting of an accessory bridge of fibrous tissue, which partially or completely divides the mitral valve into two orifices.

What type of orifice tapping is commonly used?

Flange taps and radius taps are the most commonly used. Flange taps are located 1 inch upstream and 1 inch downstream of orifice plates for pipe sizes greater than 2″, and cannot be used for pipes smaller than 1.5″ diameter, but not recommended below 2″.

What is the difference between orifice and expansion valve?

Expansion valves are an active device, they regulate the flow of refrigerant to the evaporator depending on evaporator temperature. An orifice tube is just a fixed nozzle that pisses refrigerant into the evaporator without any sort of feedback.

How far should the valve and orifice go into the venturi tube?

Insert the valve and orifice into the venturi tube until the orifice is visible in the air intake hole. This may be as little as 1/8″ in some newer stainless steel tube burners with the air baffle near the end of the tube.

What is orifice in refrigeration system?

An orifice tube has no moving parts and contains a permanent restriction within the system. The orifice tube systems control the refrigerant flow through other means, such as cycling the compressor on and off, or the use of a refrigerant regulating valve within the compressor itself.

What is an orifice pipe?

orifice [tube pipe] definition, orifice [tube pipe] meaning | English dictionary. orifice. n (Engineering) a plate having a central hole that is placed across the flow of a liquid, usually between flanges in a pipeline.
