What happens if you open the ball valve is not fully?

Water supply in modern homes, various kinds of pipes, for which she enters the apartment tenants. A special taps and valves are used to regulate the pressure. Currently, the commonly used models of ball valves. Keep in mind that it is best to use it only in the form of open or closed, but not half! Why? Let's face it.

Design and operation principle

To understand why this kind of special demands, we must remember its design and the basic working principle.

Device

In most cases, the construction cranes are installed rings of polytetrafluorethyleneIntended to seal the components. They are located between the gate in the form of a hollow sphere and the main body.

PTFE rings are mounted with a special element with a thread that connects the components of the crane.

Gate It has a small opening, which provides a loose fit design.

Principle of operation

On admission of water under high pressure ball valve can be moved to the PTFE ring and presses it. This operating principle provides structural integrity and did not allow water to freely go outside.

Ball valve intended for operation in two positions.

Reference. Changing the position of the crane is achieved by rotating by 90 °.

In this case the rim restrictive special mark, preventing further passage of the valve.

In the closed position element no water flows through the valve element. BUT in the open position creates a laminar flow of water without disturbing the operating conditions.

What happens with the mechanism open half

The only best one operation is the work of a crane in a closed or open position. When opening the shutter water passes without hindrance along the hollow tube and out. but when you open the faucet in the half gear changes occur.

additional pressure

With a partial closure of the water flows, not directly, but at an angle.

Important! fluid delivery angle creates additional pressure on the gate. As a result, it may cause deformation and breakage of the structure of the mechanism.

With prolonged use of the crane in a position PTFE rings can be damaged and the locking elements. This can cause leakage.

eddy

By turning the valve element is also not completely occurs turbulent water movement through the tube. Such flow creates excessive hydrodynamic pressure on all structural elements.

Median position the shutter does not allow to regulate the water pressure, since it does not form a laminar and turbulent flow. At the output of the mixed stream is formed, wherein a liquid dispersion of large radius.

Additional corrosion

With the passage of the water at an angle there are areas where you do not pass it. In these places, they accumulate deposits of heavy metals.

Important! Using a crane, half open, resulting in additional wear and corrosion material.

In the end, incorrect closing of the shutter causes damage to the structure.

Other methods of controlling water pressure

If you need to adjust the water pressure, you can use one of the following options.

The easiest way is complete change mechanism. Initially, the need to dismantle the ball valve. It is important to cut off the water! Followed by a set-date model mixer with the possibility of controlling water supply.

A more complex embodiment is the installation of an additional element, regulating pressure and the maximum pressure in the system. The complexity of the present embodiment lies in the fact that elements are installed in the pipe after the rotary valve.
