What is a rotary valve?

The rotary valve is a mechanism that changes the path of liquids or gases by means of a circular rotating closure. It contrasts with a linear valve that moves up and down to control the flow. Rotary valves usually take less space than linear valves when performing the same basic function. Some swivel valves have a design of air air valves that allow them to use in pressure conditions.

Any valve that uses a circular movement to control flow is the type of rotary valve. The "rotary valve" is a wide term that covers a wide range of applications. Naturally, the valves are used in plumbing and production, but are also used in internal combustion engines, music instruments and human body. Even the rotating door is a type of rotary valve.

The ball valve is a common type of rotary valve. It is also called StopCock valve. The smoke valve is round with the hole through its center, which is rotated by the handle. Inserted into the pipe, can be closed, partially openor completely open, allowing a certain degree of flow control. This category also includes butterfly valve. It is a more efficient space than a spherical valve because the closing mechanism is a flat disk. The disk is connected to the pipe at the top and bottom and on the vertical axis using the hand wheel. A similar valve is a tilting disc, which is used in prosthetic hearts.

musical tools such as tube, French horn and trombone valve also use rotary valves. The levers - commonly called keys - operate the valves and allow air to flow into another hose line. This creates another set of notes. The valves serve for two purposes: open a new way for air and close an alternative path. If the alternative way is not completely sealed, then the musical sound is endangered.

Some combustion engines use a very sophisticated type of rotary valve. In this case, the valve closure is shaped as ZaoBleed triangle and mounted in elongated closure. The tips of the triangle form a seal with closing, creating air pockets. As the engine turns, all four combustion cycle punches - reception, compression, combustion and exhaust - are finished in one movement.

The rotary feeder is the type of air valve. The feeder transmits solids from one chamber to another without changing the pressure. Rotary feeders are often used in production devices that deal with granulated solids.
