Valves of the world

A ball valve, a type of one-quarter turn valves, is quite literally a ball placed in a passage through the fluid flow. The ball has a hole through it, which open and close the valve. When the ball's location, so that the hole running the same direction as a channel, just fluid flowing through holes in the valve is open. However, when the ball's location, so that the hole is vertical channels, fluid can not be passed, and valves closed. The ball is from external control valve, and treatment is often 90 degrees, or at the turn of the first quarter, back and open and close the valve.

Basic ball valve, as mentioned above, is a two-way valve. This ball valves have a single, direct access, drilling through the ball, so that the two openings: one, on each side, into a socket. A ball valve can also become a three-way valve, if the third hole was bored through part of the ball until it meets the main hole, the formation of a spoon, three-way valve can close one or all of the three channels, which connect .

As in nature, ball valve, this does not work and the circumstances under which the fine control valve is necessary, such as control of the throttle valve, in a car. However, the valve works very well in the circumstances under which the flow needs to completely shut down, such as shut-off valve on the main supply line, in your house. Valve did not tend to development issues, if they are not used for a very long time, they will still work again when absolutely necessary.

There are three different types of ball valve. A full port ball valve to provide any traffic restrictions, which means that when the valve is open, free flow of liquid through it. To achieve this goal, passed the ball more than size, so that the holes bored through it the same size can be passed. A standard port ball valve is not large, so the hole is a size smaller than channel. This small number of restrictions on the movement of fluid through the valve. Reduction of port ball valve, on the other hand, there is a smaller ball and a smaller hole, creating a huge traffic restrictions, fluid through the valve.
