What is a lever valve?

The lever valve is a simple device installed in plumbing systems that ensure fast and easy interruption of the flow of liquid, gas or sludge via the water system. The lever is an outer part of the valve that moves to the position perpendicular to the pipe to completely close the valve. The valve itself is actually a ball valve; The term “lever valve” concerns the control mechanism. When the valve is fully open, the substance flows through the unlimited; When the valve is closed, the passage is completely blocked. Many valves are designed to allow the user to control the flow to a high degree of accuracy; For example, the valves with which most people are known, hot and cold water on the sinks generally allow users to open the valve into any desired degree. When controlling circular controls such as the wheels valve completely.

In addition to the control flow valves from the system contains most plumbingSystems of a number of valves that regulate the flow in the system. In the common household plumbing system, one of the main reasons for such valves is to facilitate maintenance and repair on the system. For example, if there is a leak in the system, it must be repaired, which requires the flow to the area where the leak has occurred. The lever valve is an excellent emergency shut -off valve, because it only requires a rapid turning of the lever by 90 degrees to turn the flow. When the lever valves were installed at strategic locations within the system, one part of the maintenance system and repairing without off the system can be insulated.

The

lever valve consists of a lever, an external control mechanism, a valve housing and a Kulgh that drilled a hole or a port. The valve case is wider than the pipe in which it is installed, and contains a cavity in which the ball fits comfortably. The alignment of the hole in the ball is controlled by the lever, and when the hole in the ball is connected to the holes at the end of the valve housing, the fabric in the pipe flows without obstacles. By turning the ballE of 90 degrees, so the hole in the ball is perpendicular to the valve holes, completely turns off the pipe flow.

Other valve types, such as gateway that usually run faucets and Cocks, are not sufficient for a rapid shutdown of flow through the system because they are designed to modulate the flow gradually, and require a lot of full turn to completely block the flow. In addition, the lever valves are built with a lever parallel to the flow when they are open, and after closing the flow perpendicular to the flow. The valve condition of the lever - open or closed - Jeznadno visible, which could be of fundamental importance in the emergency situation where the precious time could be lost when trying to determine the valve status with a circular steering mechanism.
